la tion, operation and maintenance to avoid dam age to
the pressure system. No attempt should be made to gain
ac cess to the component parts of the pressure sys tem other
than by suitably trained and quali ed per son nel.
Electrical
The unit must be grounded. No in stal la tion or main-
te nance work should be attempted on the electrical
equip ment without rst switching OFF, isolating and
lock ing-off the power supply. Work on live equipment
must only be carried out by suitably trained and quali ed

per son nel. No attempt should be made to gain access to
the con trol panel or electrical enclosures during nor mal
op er a tion of the unit.
Rotating Parts
Fan guards must be tted at all times and not removed
unless the power supply has been isolated. If ductwork is
to be tted, requiring the wire fan guards to be re moved,
alternative safety measures must be taken to protect
against the risk of injury from rotating fans.
Sharp Edges
The nning on the air cooled con dens er coils has sharp
metal edges. Reasonable care should be taken when
working in contact with the coils to avoid the risk of
mi nor abra sions and lac er a tions. The use of gloves is
recommended.
Refrigerants and Oils
Refrigerants and oils used in the unit are generally non-
toxic, non- ammable and non-corrosive, and pose no
spe cial safety hazards. Use of gloves and safety glass es
are, however, recommended when working on the unit.
The build up of refrigerant vapor, from a leak for ex-
am ple, does pose a risk of asphyxiation in con ned or
enclosed spac es and attention should be given to good
ven ti la tion.
High Temperature and Pressure Cleaning
High temperature and pressure cleaning methods (e.g.
steam cleaning) should not be used on any part of the
pressure system as this may cause operation of the pres-
sure relief device(s). Detergents and solvents which may
cause corrosion should also be avoided.
EMERGENCY SHUTDOWN
In case of emergency the electrical option panel is t ted
with an emergency stop switch CB3 (Circuit Break er
3). Separate Circuit Break ers, CB1 (Sys tem 1) and CB2
(Sys tem 2), can also be used to stop the re spec tive sys-
tem in an emer gen cy. When op er at ed, CB3 re moves the
elec tri cal supply from the con trol sys tem, thus shut ting
down the unit.

INTRODUCTION
YORK YCAS chillers are designed for water or wa-
ter-glycol cooling. All units are designed to be lo cat ed
outside on the roof of a building or at ground level.
The units are completely assembled with all in ter con -
nect ing refrigerant piping and internal wiring, ready for
eld installation.
Prior to delivery, the unit is pressure tested, evacuated,
and fully charged with refrigerant and oil in each of the
two independent refrigerant circuits. After assembly,
an operational test is performed with water owing
through the evaporator to ensure that each refrigerant
cir cuit operates correctly.
The unit structure is manufactured from heavy gauge,
galvanized steel. All external structural parts are coat ed
with “Desert Sand” baked-on enamel powder paint. This
provides a nish which, when subjected to ASTM B117,
500 hour, 5% salt spray conditions, shows breakdown
of less than 1/8" either side of a scribed line (equiv a lent
to ASTM D1654 rating of “6”).
All exposed power wiring is be routed through liquid-
tight, non-metallic conduit.
General Description
The Air Cooled Screw Chiller utilizes many com po nents
which are the same or nearly the same as a stan dard
reciprocating chiller of a similar size. This in cludes
mod u lar frame rails, condenser, fans and evap o ra tor.
The chiller consists of 2 screw compressors in a cor re -
spond ing number of separate refrigerant circuits, a sin gle
shell and tube DX counter ow evaporator, econ o miz ers,
an air cooled condenser, and expansion valves.
Compressor
The semi-hermetic rotary twin-screw compressor is
designed for industrial refrigeration applications and
ensures high operational ef ciencies and reliable per-
for mance. Capacity control is achieved through a sin gle
slide valve. The compressor is a positive dis place ment
type characterized by two helically grooved rotors which
are manufactured from forged steel. The 60 Hz motor op-
erates at 3550 RPM to direct drive the male rotor which
in turn drives the female rotor on a light lm of oil.

Refrigerant gas is drawn into the void created by the
unmeshing of the ve lobed male and seven lobed
fe male rotor. Further meshing of the rotors closes
the ro tor threads to the suction port and progressively
com press es the gas in an axial direction to the discharge
port. The gas is compressed in volume and increased
in pressure before exiting at a designed volume at the
dis charge end of the rotor casing. Since the intake and
dis charge cy cles overlap, a resulting smooth ow of gas
is maintained.
The rotors are housed in a cast iron compressor hous ing
precision machined to provide optimal clearances for
the rotors. Contact between the male and female rotor
is pri ma ri ly rolling on a contact band on each of the
rotors pitch circle. This results in virtually no rotor
wear and in creased reliability, a trademark of the screw
com pres sor.
The compressor incorporates a complete anti-friction
bearing design for reduced power input and increased
reliability. Four separated, cylindrical, roller bearings
handle radial loads. Angular-contact ball bearings
han dle axial loads. Together they maintain accurate rotor
po si tion ing at all pressure ratios, thereby min i miz ing
leak age and maintaining ef ciency. A springless check
valve is installed in the compressor discharge housing
to pre vent compressor rotor backspin due to system
re frig er ant pressure gradients during shut down.
Motor cooling is provided by suction gas from the
evap o ra tor flowing across the motor. Redundant
over load pro tec tion is provided using both thermistor
and cur rent over load protection.
The compressor is lubricated by removing oil from
the refrigerant using an external oil separator. The
pres sur ized oil from the oil separator is then cooled in
the condenser coils and piped back to the compressor for
lubrication. The com pres sor design working pressure is
450 PSIG (31 bar). Each chill er receives a 300 PSIG (21
bar) low side and a 450 PSIG (31 bar) high side factory
test. A 350 watt (115-1-60) cartridge heat er is located
in the com pres sor. The heat er is tem per a ture activated
to prevent re frig er ant condensation.
The following items are also included:
An acoustically tuned, internal discharge muf er to
min i mize noise, while maintaining max i mum ow
and performance.
Discharge shutoff valve.
A rain-tight terminal box.
A suction gas screen and serviceable, 0.5 - 3.0
micron full ow oil lter within the compressor
housing.
Evaporator
The system uses a high ef ciency Shell and Tube type
Di rect Ex pan sion Evaporator. Each of the 2 re frig er ant
circuits consists of 4 passes with the chilled liq uid
cir cu lat ing back and forth across the tubes from one
end to the other.
The design working pressure of the standard evaporator
on the shell side is 150 PSIG (10 bar), and 350 PSIG (24
bar) for the tube (refrigerant side). The water baf es
are fab ri cat ed from galvanized steel to resist corrosion.
Re mov able heads are provided for access to internally
en hanced, seamless, copper tubes. Water vent and drain
con nec tions are included.
The evaporator is equipped with a heater for protection
to -20°F (-29°C) ambient and in su lat ed with 3/4" (19
mm) exible closed-cell foam.
The water nozzles are provided with grooves for
me chan i cal couplings and should be insulated by the
con trac tor after pipe installation.
Condenser
The n and tube condenser coils are manufactured
from seamless, internally enhanced, high condensing
co ef cient, corrosion resistant copper tubes arranged in

stag gered rows and mechanically expanded into cor ro sion
resistant aluminum alloy ns with full height n col lars.
They have a design working pressure of 450 PSIG
(31 bar). Each coil is rested to 495 PSIG (34 bar).
Multiple fans move air through the coils. They are
dy nam i cal ly and statically balanced, direct drive with
cor ro sion re sis tant glass ber reinforced composite
blades mold ed into low noise, full airfoil cross section,
pro vid ing vertical air discharge from extended ori ces
for ef cien cy and low sound. Each fan is located in a
sep a rate com part ment to prevent cross ow during fan
cy cling. Guards of heavy gauge, PVC coated galvanized
steel are pro vid ed.
The fan motors are high ef ciency, direct drive, 6-pole,
3-phase, Class- “F,” current overload protected, totally
en closed (TEAO) type with double sealed, per ma nent ly
lubricated ball bearings.
Economizer
Economizer is a refrigerant to refrigerant, compact plate-
type heat exchanger to maximize chiller capacity and
ef ciency by subcooling liquid refrigerant delivered to
the cooler expansion valve. Constructed of corrosion
resistant stainless steel plates formed to induce turbulent
ow and enhance heat transfer, then oven brazed and
pressure tested for reliability. Designed and constructed
with ASME and TÜV certi cation for 31 bar (450 psig).
UL/CSA listed.
Oil Separator/System
The external oil separator, with no moving parts and
de signed for minimum oil carry-over, is mounted in
the dis charge line of the compressor. The high pressure
dis charge gas is forced around a 90 degree bend. Oil is
forced to the outside of the separator through cen trif u gal
action and captured on wire mesh where it drains to the
bottom of the oil separator and ows to the condenser
for cooling before returning to the compressor.
The oil (YORK “L” oil – a POE oil used for all re frig -
er ant applications), which ows back into the com-
pres sor through a replaceable 0.5 - 3.0 micron oil lter,
is at high pressure. This high pres sure “oil injection”
forces the oil into the com pres sor where it is fed to the
bearings for lubrication. After lubricating the bearings,
it is injected through ori ces on a closed thread near
the suction end of the rotors. The oil is automatically
in ject ed because of the pressure difference between the
discharge pres sure and the reduced pressure at the suc-
tion end of the rotors. This lubricates the rotors as well as
provides an oil seal against leakage around the ro tors to
assure re frig er ant compression (volumetric ef cien cy).
The oil also provides cooling by transferring much of
the heat of com pres sion from the gas to the oil keeping
dis charge tem per a tures down and reducing the chance
for oil breakdown. Oil injected into the rotor cage ows
into the ro tors at a point about 1.2x suction. This assures
that a required minimum differential of at least 30 PSID
(2.1 bar) exists between discharge and 1.2x suc tion, to
force oil into the rotor case. A minimum of 10 PSID
(0.6 bar) is all that is re quired to assure pro tec tion of
the compressor. Oil pressure safety is mon i tored as the
dif fer ence between suction and the pres sure of the oil
en ter ing the ro tor case.
Maximum working pressure of the oil separator is 450
PSIG (31 bar). Oil level should be above the midpoint
of the “low er” oil sight glass when the compressor is
run ning. Oil level should not be above the top of the
“up per” sight glass.
Oil Cooling
Oil cooling is provided by routing oil from the oil sep a -
ra tor through several of the top rows of the con dens er
coils and back to the compressor.
Capacity Control
The compressors will start at the minimum load po si tion
and provide a capacity control range from 10% - 100%
of the full unit load using a continuous function slide
valve. The microprocessor modulates a voltage signal to
a 3-way pres sure reg u lat ing capacity control valve which
controls com pres sor capacity, in de pen dent of system
pressures, and balances the com pres sor ca pac i ty with
the cool ing load. Loading is ac com plished by varying
pressure through the pressure regulating ca pac i ty control
valve to move the slide valve against the spring pressure
to promote stable smooth loading.
Automatic spring return of the slide valve to the min-
i mum load position will ensure compressor start ing at
min i mum motor load.
Power and Control Panel
All controls and motor starting equipment are factory
wired and function tested. The panel enclosures are
de signed to IP55 and are manufactured from powder
paint ed galvanized steel.
The Power and Control Panel are divided into power
sec tions for each compressor and associated fans, a con-
trol section and an electrical options section. The pow er
and control sections have separate hinged, latched, and
gasket sealed doors equipped with wind struts.

Each power compartment contains:
Compressor and fan starting contactors, fan motor
ex ter nal overloads, control circuit serving compressor
ca pac i ty control, compressor and fan contactor coils and
compressor motor overloads. (Fig #1, page 12)
Current transformers in the 2ACE module provide
compressor motor over load protection and sense each
phase. This protects the compressor motors from
dam age due to: low current input, high input current,
un bal anced current, single phasing, phase reversal, and
com pres sor locked rotor.
The control section contains:
ON/OFF switch, microcomputer keypad and display,
mi cro pro ces sor board, I/O expansion board, relay boards
and power supply board.
The options sections contain:
A control circuit transformer complete with service
switch providing 115/1/60 Hz power to the unit con trol
system.
Electrical options as described in “Accessories and
Options.”
Microprocessor Controls
The microprocessor has the following functions and
displays:
A liquid crystal 40 character display with text pro-
vid ed on two lines and light emitting diode back-
light ing out door viewing.
A color coded, 35 button, sealed keypad with sec-
tions for Display, Entry, Setpoints, Clock, Print,
Pro gram and Unit ON/OFF.
The standard controls shall include: brine chilling,
ther mal storage, automatic pump down, run signal
con tacts, demand load limit from external building
automation sys tem input, remote reset liquid temperature
reset in put, unit alarm contacts, chilled liquid pump
control, au to mat ic reset after power failure, automatic
system op ti mi za tion to match operating conditions.
The software is stored in non-volatile memory (EPROM)
to eliminate chiller failure due to AC power failure. The
Programmed Setpoints are stored in lithium battery
backed memory.
Motor Current Protection
The microprocessor motor protection provides high
cur rent protection to assure that the motor is not
damaged due to voltage, excess refrigerant, or other
problems that could cause excessive motor current. This
is ac com plished by sending a current signal pro por tion al
to motor current from the Motor Protector mod ule to the
I/O Expansion board to be multiplexed and sent to the
Microprocessor Board. If the motor cur rent exceeds
the 115% FLA trip point after 3 seconds of op er a tion
on either Wye-Delta or ACL starters, the mi cro will
shut the system down and lock it out after one fault.
A manual reset of the re spec tive system switch is
re quired to clear the fault and restart the system. A
thor ough check of the mo tor, wiring, and refrigerant
system should be done be fore restarting a system that
has fault ed on high motor current.
The micro also provides low motor current protection
when it senses a motor current less than 10% FLA.
The micro will shut the system down whenever low
motor current is sensed and will lock out a system if
three faults occur in 90 minutes. Low motor current
pro tec tion is activated 4 seconds after start on both
Wye-Delta and ACL starters to assure the motor starts,
the sys tem doesn’t run with out refrigerant, the motor
protector is not tripped, and the mechanical high pres sure
cut-out is not tripped. Once the system is locked out
on Low Motor Current, it must be manually reset with
the sys tem switch. See also Motor Protection Module
section below.
The micro senses low motor current whenever a HPCO
or Motor Protector contact opens. This occurs because
the MP and HPCO contacts are in series with the mo tor
contactor. Whenever either of these devices are open,
the contactor de-energizes and the motor shuts down.
Since the micro is sending a run signal to the contactor,
it senses the low motor current below 10% FLA and
shuts the system down.

Motor Protection Modules (2ACE)
The mechanical motor protector is a Texas In stru ments
2ACE Three Phase Protection Module (Fig. 45, page
127), provides thermal and cur rent motor overload pro-
tec tion. This mod ule also pro tects against phase to phase
cur rent im bal ance, over cur rent, under current, and phase
ro ta tion. The mod ules, mount ed in the power pan els,
uti liz es a 7 seg ment display which provides op er at ing
sta tus and fault di ag nos tic in for ma tion. The 7 segment
dis play will dis play ei ther a sta tion ary or a ash ing al-
pha nu mer ic value which can be de cod ed by the op er a tor.
A list of the codes follows:
HAXXX Normal motor OFF display. Sequentially
sweeps through the motor protection dip
switch setting.
0 Normal - no fault detected (Running)

4 Improper in com ing phase ro ta tion.
5 High motor tem per a ture. Trip point =

6 Communication error.
7 Unload imbalance ( > 50%)
8 Phase Loss (> 60%)
E Out of range of RLA cal i bra tion.
Other symbols Defective module or supply volt age.
Working voltage 18 - 30 VAC, 24 VAC nominal.
Low volt age trip = 15 VAC.
Whenever a motor protector trips, the motor pro tec tor
contacts wired in series with the motor contacts opens
and the motor contactor de-energizes causing the mo tor
to stop. The micro senses the low motor current and
shuts the system down. The micro will try two more
starts be fore locking the system out. The system locks
out be cause the motor protector is a man u al re set
de vice. Af ter the rst start, the modules’ contacts
will be open pre vent ing the motor contactors from
en er giz ing. Power must be removed and re applied to
re set the mod ule. Use CB3 in the Micro Panel to cycle
power.
Current Overload
The 2ACE module design uses one integral current
trans form er per phase to provide protection against
rap id current over load conditions. The module re sponds
to changes in current and must be cal i brat ed using DIP
switches lo cat ed on the module. Integral trip curves al-
low for in-rush cur rents dur ing Wye-Delta, part wind,
or ACL starts with out nuisance tripping.
To check the factory setting of the 2ACE module cur rent
overload trip value. See Table 1 (pages 18 and 21).
For the location of the dip switches and determining the
ON side of the switches, refer to Fig ure 45, page 127. As
in di cat ed, to place a switch in the ON po si tion re quires
push ing the switch to the left.
A switch must be pushed to the left to
place the switch in the ON position.
The numerical value for the combi-
nation of "ON" switches equals the
overload setting.
It is recommended that a YORK Ser-
vice Tech ni cian or the YORK fac to ry
be con sult ed before chang ing these
settings for any rea son, since dam-
age to the com pres sor could re sult.
Chang es should nev er be made un-
less it is ver i ed that the set tings are
in cor rect.
Anytime a dip switch change is made,
pow er must be cycled off and on to the
module to re pro gram the mod ule to the
new value.

Thermal Overload
Three PTC (positive temperature co ef cient) ther mistors
in the motor windings provides thermal pro tec tion. The
sensor re sis tance stays rel a tive ly con stant at 1k until
a tem per a ture of 266°F (130°C) is sensed. The sensor
ex pe ri enc es a rapid rise in re sis tance be yond this tem-
per a ture. When ev er the re sis tance of one of the sen sors
reach es 13kΩ, +/− 3k, the 2ACE module trips, which
ul ti mate ly de-energizes the mo tors pi lot cir cuit. Re set
is manual after the mo tor cools and the sen sor re sis tance
drops to 3.25kΩ, +/− 0.5k.
Current Imbalance (Loaded & Unloaded)/
Loss of Phase
A 2 second delay at start-up allows for any imbalances
resulting during normal starting conditions. After this
ini tial delay, the 2ACE module compares the “Op er -
at ing Current” to the measured half line current. The
“Op er at ing Current” is given by 0.65 X factory overload
cur rent setting.
An unloaded compressor condition occurs when any
measured half line current is less than the “Operating
Current.” A current imbalance exceeding an unloaded
level of 25% will result in the motor pilot circuit being
de-energized.
A loaded compressor condition occurs when any mea-
sured half line current is great er than or equal to the
“Operating Current.” A cur rent imbalance exceeding a
loaded level of 17% will result in the motor pilot cir cuit
being de-energized.
Imbalance is de ned as
(High Phase - Low Phase)/High Phase
Improper Phase Sequence
The 2ACE module calculates the phase sequence at
start-up using the three cur rent transformers to de-
ter mine wheth er the three phase sequence on the load
side of the main contactor is miswired. Upon de tec tion
of a miswired motor load, the mod ule will de-energize
the main contactor pi lot circuit within 50 millisecond
re sponse time.

MOTOR STARTING
Two types of compressor motor starting are available:
Across-the-Line and optional Wye-Delta Open Tran-
si tion Start er.
Across-the-Line starters will utilize one contactor and
one start relay per compressor. The optional Wye-Delta
start er utilizes 4 motor contactors, a transition delay
re lay, a start relay, and a start-wye relay.
The Wye-Delta start allows inrush current to be limited
to approximately 33% LRA for the rst 4 to 7 sec onds,
with current increasing to normal running cur rent when
the Delta connection is completed.
When the micro initiates a start signal at Relay Output
Board #1 (SYS 1) Terminal 20 or Relay Output Board
#2 (SYS 2) Ter mi nal 20 to run a com pres sor, the 1CR
(SYS 1) or 2CR (SYS 2) relay is en er gized. The tran-
si tion of the 1CR (SYS 1) or 2CR (SYS 2) relay contacts
en er giz es the 1S (SYS 1) or 2S (SYS 2) relay approx.
16ms later. The 1S/2S con tacts in turn en er gize the 1M
(SYS 1) or 3M (SYS 2) mo tor con tacts 16ms later. This
com pletes the “WYE” con nec tion of the motor start.
At the same time, the normally closed 1S/2S auxiliary
in ter lock con tact opens pre vent ing the 2M and 1 TRX
(SYS 1) or 4M and 2 TRX (SYS 2) mo tor contactors
from en er giz ing. 2 sets of aux il ia ry con tacts from 1M
(SYS 1) or 3M (SYS 2) close, in ter lock ing the 1M (SYS
1) or 3M (SYS 2) contactors, keep ing them en er gized
in par al lel with 1S (SYS 1) or 2S (SYS 2).
The “WYE” connection of the motor start is enabled
for 4 to 7 seconds depending upon motor current as
sensed by the microprocessor. The tran si tion to Delta
takes 7 seconds if current is below 110% FLA. If mo-
tor current exceeds 110% FLA, the transition is made
to Delta as long as the WYE has been enabled for at
least 4 seconds.
After the “WYE” connection is enabled for 4 to 7
sec onds, the 1TR (SYS 1) or 2TR (SYS 2) transition
delay relay is enabled by the microprocessor from Relay
Out put Board #1 Terminal 8 (SYS 1) or Relay Out put
Board #2 Terminal 6 (SYS 2). The 1TR (SYS 1) or 2TR
(SYS 2) contacts open, de-energizing 1S (SYS 1) or 2S
(SYS 2). 1M (SYS 1) or 3M (SYS 2) remain energizes
through 2 sets of interlocking con tacts 1M (SYS 1) or
3M (SYS 2). Open ing of the 1TR (SYS 1) or 2TR (SYS
2) con tacts deenergizes 1S/2S and clos es the nor mal ly
closed 1S (SYS 1) or 2S (SYS 2) con tacts, en er giz ing
1 TR, 1 TRX, 2 TR, and 2 TRX are
NOT “tim ing” re lays. These devices
are sim ply pilot relays iden ti cal to
1CR and 2CR.

HANDLING AND STORAGE
DELIVERY AND STORAGE
To ensure consistent quality and maximum reliability, all
units are tested and inspected before leaving the fac to ry.
Standard units are shipped completely assembled and
con tain ing refrigerant under pressure. Units are shipped
with out export crating unless this has been speci ed on
the Sales Order.
Units with remote evaporators will have the chiller and
remote evaporator charged with nitrogen.
If the unit is to be put into storage, prior to installation,
the following precautions should be observed:
Unit must be “blocked” so that the base is not
per mit ted to sag or bow.
Ensure that all openings, such as water con nec tions,
are securely capped.
Do not store where exposed to ambient air tem per a-
tures exceeding 110°F (43°C).
The condensers should be covered to protect the ns
from potential damage and corrosion, par tic u lar ly
where building work is in progress.
The unit should be stored in a location where there
is minimal activity in order to limit the risk of ac-
ci den tal physical damage.
To prevent inadvertent operation of the pressure
relief devices the unit must not be steam cleaned.
It is recommended that the unit is periodically in-
spect ed during storage.
INSPECTION
Remove any transit packing and inspect the unit to en-
sure that all components have been delivered and that
no damage has occurred during transit. If any dam age
is evident, it should be noted on the carrier's freight bill
and a claim entered in accordance with the in struc tions
giv en on the advice note.
Major damage must be reported immediately to your
lo cal YORK representative.
MOVING THE CHILLER
Prior to moving the unit, ensure that the installation
site is suitable for installing the unit and is capable of
sup port ing the weight of the unit and all associated
ser vic es.
The units are designed to be lifted using ca bles. A
spread er bar or frame 88" (2250 mm) wide should be
used in order to prevent damage to the unit from the
lifting chains (See Figures 3 and 4).
Units are provided with lifting eyes extending from the
sides of the base frame which can be attached to di rect ly
using shackles or safety hooks (See Figure 4).
The unit must only be lift ed by the base frame at the
points provided. Nev er move the unit on roll ers, or
lift the unit using a forklift truck.
Care should be taken to avoid damaging the con dens er
cooling ns when moving the unit.
Lifting Weights

INSTALLATION
LOCATION REQUIREMENTS
To achieve optimum performance and trouble-free
ser vice, it is essential that the proposed installation
site meets with the location and space requirements
for the model being installed. For dimensions, weight
and space requirements, including service access, refer
to the Technical Data Section.
It is important to ensure that the minimum service ac-
cess space is maintained for cleaning and main te nance
purposes.
OUTDOOR INSTALLATIONS
The units can be installed at ground level, or on a
suitable rooftop location. In both cases an adequate
sup ply of air is required. Avoid locations where the
sound out put and air discharge from the unit may be
ob jec tion able.
The location should be selected for minimum sun ex-
po sure and away from boiler ues and other sources of
airborne chemicals that could attack the condenser coils
and steel parts of the unit.
If located in an area which is accessible to un au tho rized
persons, steps must be taken to prevent access to the
unit by means of a protective fence. This will help to
prevent the possibility of vandalism, accidental dam age,
or possible harm caused by unauthorized re mov al of
pro tec tive guards or opening panels to expose ro tat ing
or high voltage components.
For ground level locations, the unit must be installed
on a suitable at and level concrete base that extends
to fully support the two side channels of the unit base
frame. A one-piece concrete slab, with footings ex-
tend ing be low the frost line is recommended. To avoid
noise and vibration transmission the unit should not be
se cured to the building foundation.
On rooftop locations, choose a place with adequate
struc tur al strength to safely support the entire op er at ing
weight of the unit and service personnel. The unit can
be mount ed on a concrete slab, similar to ground oor
locations, or on steel channels of suitable strength. The
channels should be spaced at the same centres as the
vibration mounting holes in the unit base frame and
must be at least 4-3/4" (120 mm) wide at the con tact
points. This will allow vibration isolators to be tted
if required.
Any ductwork or attenuators tted to the unit must
not have a total static pressure resistance, at full unit
air ow, exceeding the capability of the fans installed
in the unit.
INDOOR INSTALLATIONS
The unit can be installed in an enclosed plant room
pro vid ing the oor is level and of suitable strength
to sup port the full operating weight of the unit. It is
es sen tial that there is adequate clearance for air ow
to the unit. The discharge air from the top of the unit
must be duct ed away to prevent recirculation of air
within the plant room. If common ducts are used for
fans, non-return damp ers must be tted to the outlet
from each fan.
The discharge ducting must be properly sized with a
total static pressure loss, together with any intake stat ic
pressure loss, less than the available static pressure
ca pa bil i ty for the type of fan tted.
The discharge air duct usually rejects outside the build-
ing through a louver. The outlet must be positioned to
pre vent the air being drawn directly back into the air
in take for the condenser coils, as such recirculation
will affect unit performance.
LOCATION CLEARANCES
Adequate clearances around the unit(s) are required for
the unrestricted air ow for the air-cooled con dens er
coils and to prevent recirculation of warm discharge
air back onto the coils. If clearances given are not
main tained, air ow restriction or recirculation will
cause a loss of unit performance, an increase in power
con sump tion and may cause the unit to malfunction.
Con sid er ation should also be given to the possibility of
down drafts, caused by ad ja cent buildings, which may
cause recirculation or un even unit air ow.
For locations where signi cant cross winds are ex-
pect ed, such as exposed roof tops, an enclosure of
sol id or lou ver type is recommended to prevent wind
tur bu lence in ter fer ing with the unit air ow.
When units are installed in an enclosure, the en clo sure
height should not exceed the height of the unit on more
than one side. If the enclosure is of louvered con struc -
tion the same requirement of static pres sure loss ap plies
as for ducts and at ten u a tors stated above.

COMPRESSOR FEET BOLT REMOVAL
After the chiller is placed in the nal location, remove
the four bolts, 1 , attaching the compressor feet to the
frame rails. These bolts are only used for shipping
purposes. The bolts are screwed into the compressor
feet from the bottom side of the frame rail. Refer to
Figure 5.
After the four shipping bolts are removed from the
compressor feet, the compressor will be held in place
by the four corner brackets, 2.
This assembly reduces compressor noise by isolating
the compressor from the base rails.
DO NOT remove the four 3/8" bolts, 3, mounting the
corner brackets, 2, to the frame rails.

VIBRATION ISOLATORS
Optional sets of vibration isolators can be supplied loose
with each unit.
Using the Isolator tables, refer to the Technical Data
Section, identify each mount and its cor rect lo ca tion
on the unit.
Installation
Place each mount in its correct position and lower the
unit carefully onto the mounts ensuring the mount en-
gag es in the mounting holes in the unit base frame.
On adjustable mounts, transfer the unit weight evenly to
the springs by turn ing the mount adjusting nuts (lo cat ed
just be low the top plate of the mount) counter-clock wise
to raise and clock wise to low er. This should be done
two turns at a time until the top plates of all mounts are
between 1/4" and 1/2" (6 and 12 mm) clear of top of
their hous ing and the unit base is level.
A more detailed installation in struc tion
is pro vid ed in the Installation Instruc-
tions for VMC Series AWR/AWMR and
CP Restrained Mountings Section of
this manual, (page 107).
SHIPPING BRACES
The chillers modular design does not require shipping
braces.
PIPEWORK CONNECTION
General Requirements
The following piping recommendations are intended
to ensure satisfactory operation of the unit(s). Failure
to follow these rec om men da tions could cause damage
to the unit, or loss of per for mance, and may in val i date
the warranty.
The maximum ow rate and pressure
drop for the evaporator must not be
ex ceed ed at any time. Re fer to the
Tech ni cal Data Sec tion for de tails.
The liquid must enter the evaporator
at the in let con nec tion. The inlet con-
nec tion for the evaporator is at the far
end of the unit when viewed from the
pow er and con trol pan els.
Water inlet is always nearest the suc-
tion gas outlet on the DX evaporators.
(chiller barrel)
A ow switch must be installed in the customer
pipework at the outlet of the evaporator and wired
back to the control panel using shielded ca ble. There
should be a straight run of piping of at least 5 pipe di-
am e ters on either side. The ow switch should be wired
to Ter mi nals 13 and 14 (see Figs. 13 and 14, pages 40
and 41). A ow switch is re quired pre vent dam age to
the evaporator caused by the unit op er at ing with out
ad e quate liquid ow.
The ow switch used must have gold plated contacts
for low voltage/current operation. Paddle type ow
switch es suitable for 150 PSIG (10 bar) (optional 300
PSIG) working pres sure and hav ing a 1" N.P.T. con-
nection can be obtained from YORK as an ac ces so ry
for the unit. Al ter na tive ly a dif fer en tial pres sure switch
sited across an ori ce plate may be used, pref er a bly of
the high/low limit type.
The chilled liquid pump(s) installed in the pipework
system(s) should discharge directly into the unit evapora-
tor section of the system. The pump(s) may be controlled
external to the unit - but an override must be wired to the
control panel so that the unit can start the pump in the
event that the liquid temperature falls below the min i mum
setting. For details refer to “Electrical Con nec tion.”
4
32 YORK INTERNATIONAL
FORM 201.19-NM1 (204)
FIG. 6 – PIPEWORK ARRANGEMENT
Pipework and ttings must be separately supported to
prevent any loading on the evaporator. Flexible con-
nec tions are recommended which will also minimize
transmission of vibrations to the building. Flexible
connections must be used if the unit is mounted on
anti-vibration mounts as some movement of the unit
can be ex pect ed in normal operation.
Pipework and ttings immediately next to the evapora-
tor should be readily de-mountable to enable cleaning
be fore operation, and to facilitate visual inspection of
the exchanger nozzles.
The evaporator must be protected by a strainer, pref-
er a bly of 30 mesh, tted as close as possible to the
liq uid inlet connection, and provided with a means
of local isolation.
The evaporator must not be exposed to ushing veloci-
ties or debris released during ushing. It is recommended
that a suitably sized by-pass and valve arrangement is
in stalled to allow ushing of the pipework system. The
by-pass can be used during maintenance to isolate the
heat exchanger without disrupting ow to other units.
Thermometer and pressure gauge connections should
be provided on the inlet and outlet connections of each
evaporator.
Drain and air vent connections should be provided at all
low and high points in the pipework to permit drain age
of the system and to vent any air in the pipes.
Liquid systems at risk of freezing, due to low ambient
temperatures, should be protected using insulation and
heater tape and/or a suitable glycol solution. The liquid
pump(s) must also be used to ensure liquid is cir cu lat ed
when the ambient temperature approaches freez ing
point. Insulation should also be installed around the
evaporator noz zles. Heater tape of 21 watts per meter
un der the insulation is recommended, supplied in de -
pen dent ly and controlled by an ambient temperature
ther mo stat set to switch on at 37°F (21°C) above the
freez ing tem per a ture of the liquid.
The liquid circulation pump must be controlled by the
unit. This will ensure that when the liquid temperature
falls within 3° or 5°F (2° or 3°C) of freez ing, the pump
will start.
The evaporator is protected by heater mats un der the in-
su la tion which are supplied from the unit con trol system
pow er supply. Dur ing risk of freezing the control sys tem
should be powered to provide the freeze pro tec tion func-
tion un less the liq uid systems have been drained.
Any debris left in the water pipework
be tween the strain er and evaporator
could cause se ri ous damage to the
tubes in the evaporator and must be
avoided. The in stall er/user must also
en sure that the quality of the wa ter
in cir cu la tion is ad e quate, with out
any dis solved gas es which can cause
ox i da tion of steel parts within the
evaporator.
WATER TREATMENT
The unit performance given in the Design Guide is based
on a fouling factor of 0.00025 ft2hr°F/Btu (0.044m2/hr
°C/kW). Dirt, scale, grease and cer tain types of water
treat ment will ad verse ly affect the heat ex chang er sur-
fac es and there fore unit per for mance. Foreign mat ter
in the water system(s) can increase the heat ex chang er
pres sure drop, reducing the ow rate and caus ing po-
ten tial damage to the heat exchanger tubes.
Aerated, brackish or salt water is not recommended for
use in the water system(s). YORK recommends that a
wa ter treatment specialist is consulted to determine the
proposed water composition will not affect the evap o -
ra tor materials of carbon steel and copper. The pH val ue
of the water owing through the evaporator must be kept
be tween 7 and 8.5.

Optional Flanges
One of two types of anges may be tted depending on
the customer or local Pressure Vessel Code re quire ments.
These are Victaulic-Adapter anges, normally supplied
loose, or weld anges which may be supplied loose or
ready tted. Victaulic-Adapter and weld ange dimen-
sions are to ISO 7005 - NP10.
REFRIGERANT RELIEF VALVE PIPING
Evaporators and oil separators are each protected
against internal refrigerant overpressure by refrigerant
relief valves. For evaporators, a pressure relief valve is
mounted on each of the main refrigerant lines connecting
the evaporator to the compressors.
It is recommended that a piece of pipe is tted to each
valve and directed so that if the valve is activated, the
release of high pressure gas and liquid cannot be a dan ger
or cause injury. For indoor installations pres sure re lief
valves should be piped to the exterior of the build ing.
The size of any pipework attached to a relief valve must
be of suf cient diameter so as not to cause resistance to
the operation of the valve. Unless otherwise spec i ed
by local regulations, internal diameter de pends on the
length of pipe required and is given by the fol low ing
formula:
D5 = 1.447 x L
Where:
D = minimum pipe internal diameter in cm
L = length of pipe in meters
If relief pipework is common to more than one valve its
cross sectional area must be at least the total re quired
by each valve. Valve types should not be mixed on a
common pipe. Precautions should be taken to ensure
that the outlet of relief valves/vent pipe remain clear of
ob struc tions at all times.
DUCTWORK CONNECTION
General Requirements
The following ductwork rec om men da tions are in tend ed
to ensure sat is fac to ry op er a tion of the unit. Failure to
follow these rec om men da tions could cause damage to
the unit, or loss of per for mance, and may invalidate the
warranty.
When ducting is to be tted to the fan discharge it is
recommended that the duct should be the same cross sec-
tional area as the fan outlet and straight for at least three
feet (1 meter) to obtain static regain from the fan.
Ductwork should be suspended with exible hangers
to prevent noise and vibration being transmitted to the
struc ture. A exible joint is also recommended be tween
the duct attached to the fan and the next section for the
same reason. Flexible connectors should not be al lowed
to concertina.
The unit is not designed to take structural loading. No
signi cant amount of weight should be allowed to rest
on the fan outlet ange, deck assemblies or condenser
coil module. No more than 3 feet (1 meter) of light
con struc tion ductwork should be supported by the unit.
Where cross winds may occur, any ductwork must be
sup port ed to prevent side loading on the unit.
PIPEWORK ARRANGEMENT
Figure #6 shows the suggested pipework arrangement
for single unit in stal la tions. For mul ti ple unit installa-
tions, each unit should be piped as shown.
CONNECTION TYPES & SIZES
For connection sizes relevant to individual models re fer
to the Technical Data Section.
EVAPORATOR CONNECTIONS
Standard chilled liquid connections on all evaporators
are of the Victaulic Groove type.

34 YORK INTERNATIONAL
FORM 201.19-NM1 (204)
If the ducts from two or more fans are to be combined
into a common duct, back- ow dampers should be t-
ted in the individual fan ducts. This will prevent re cir -
cu la tion of air when only one of the fans is running.
Units are supplied with outlet guards for safety and to
prevent damage to the fan blades. If these guards are re-
moved to t ductwork, adequate alternative pre cau tions
must be taken to ensure persons cannot be harmed or
put at risk from rotating fan blades.
ELECTRICAL CONNECTION
The following connection rec om men da tions are in-
tend ed to ensure safe and sat is fac to ry operation of the
unit. Failure to follow these recommendations could
cause harm to persons, or damage to the unit, and may
in val i date the warranty.
No additional controls (re lays, etc.)
should be mount ed in the control
pan el. Power and con trol wiring not
con nect ed to the con trol pan el should
not be run through the control pan el.
If these pre cau tions are not fol lowed it
could lead to a risk of elec tro cu tion. In
ad di tion, elec tri cal noise could cause
mal func tions or dam age the unit and
its con trols.
After connection do not switch on
main pow er to the unit. Some in ter nal
com po nents are live when main power
is switched on and this must only be
done by Au tho rized persons.
POWER WIRING
All electrical wiring should be carried out in ac cor dance
with local regulations. Route properly sized cables to
cable entries on both sides of the unit.
In accordance with U.L. Standard it is the re spon si bil i ty
of the user to install overcurrent pro tec tion devices
be tween the supply con duc tors and the power supply
ter mi nals on the unit.
To ensure that no eddy currents are set up in the power
panel, the cables forming each 3-phase power supply
must enter via the same cable entry.
All sources of supply to the unit must
be taken via a common point of iso-
la tion (not sup plied by YORK).
STANDARD UNITS WITH MULTI POINT POWER
SUPPLY WIRING
Standard units require two 3-phase sep a rate ly fused 3-
wire supplies plus a ground per re frig er ant system. One
supply to be connected to each of the power panels.
Connect each of the main 3-phase supplies to the cir-
cuit breakers, non-fused disconnect switches or ter mi nal
boards located in the power panels using lug sizes de-
tailed in the Technical Data Section.
Connect the ground wires to the main protective ground
terminals in each power panel.
Units with Single-Point Power Supply Wiring
Units require only one 3-phase supply plus ground.
Connect the 3-phase supplies to the terminal block or
non-fused disconnect switch/circuit breaker located in
the options pan el using lug sizes detailed in the Techni-
cal Data Section.
Connect a ground wire to the main protective ground
terminal.
115VAC CONTROL SUPPLY TRANSFORMER
A 3-wire high voltage to 115VAC supply transformer
is standard in the chiller. This transformer steps down
the high voltage supply to 115VAC to be used by the
Micro Panel, Pow er Pan el com po nents, so le noids, heat-
ers, etc.
The high voltage for the transformer pri ma ry is taken
from the chiller input to one of the sys tems. Fusing is
provided for the trans form er.
It is important to check that the cor-
rect primary tap ping has been used
and that it con forms to the site high
volt age sup ply.
Installation
35
YORK INTERNATIONAL

Removing high voltage power to the
chill er will re move the 115VAC sup-
ply voltage to the mi cro pro ces sor cir-
cuit ry and the evap o ra tor heater. In
cold weath er, this could cause serious
dam age to the chill er due to evap o ra tor
freeze-up. Do not re move power un less
alternate means are taken to as sure
op er a tion of the evap o ra tor heat er.
Remote Emergency Stop Device
If required, a remote emergency stop de vice can be wired
into the unit. The device should be wired into ter mi nals
31 and 32 (Figs. 13 and 14, pages 40 and 41.) in the
mi cro pro ces sor con trol pan el.
CONTROL PANEL WIRING
All wiring to the control panel terminal block terminals
13-19 is nom i nal 30VDC and must be run in shielded
cable, with the shield grounded at the panel end only.
Run shielded ca ble sep a rate ly from mains cables to
avoid electrical noise pick-up. Use the control panel
cable entry to avoid the pow er cables.
The voltage free contacts supplied must be suitable for
30VDC (gold contacts recommended). If the voltage
free con tacts are from a relay or contactor, the coil of
the device must be suppressed using a standard R/C
sup pres sor. The above precautions must be taken to
avoid electrical noise which could cause a malfunction
or dam age to the unit and its controls.
The length of cable to these terminals must not exceed
25 ft. (7.5 m) unless an isolator is t ted.
VOLTS FREE CONTACTS
Chilled Liquid Pump Starter
Terminals 25 and 26 (Figs. 13 and 14, pages 40 and 41)

Alarm Contacts
Each system has a voltage-free change over contact
which will operate to signal an alarm condition when-
ev er a system locks out, or there is a power failure. To
obtain system alarm signal, connect the alarm circuit
to volt free terminals 23 and 24 (Figs. 13 and 14, pages
40 and 41) for No. 1 Sys tem and to ter mi nals 27 and 28
(Figs. 13 and 14) for No. 2 Sys tem.
SYSTEM INPUTS
Flow Switch
A chilled water ow switch, (either by YORK or others)
MUST be installed in the leaving water piping of the
evaporator. There should be a straight horizontal run of
at least 5 diameters on each side of the switch. Adjust
the ow switch paddle to the minimum ow allowed
through the evaporator. (See manufacturer's instructions
furnished with the switch.) The switch is to be wired to
terminals 13 - 14 of CTB1 located in the control panel,
as shown on the unit wiring diagram.
Remote Run / Stop
Connect remote switch(es) in series with the ow switch
to provide remote run/stop control if required.
Remote Print
Closure of suitable contacts connected to terminals 13

COMMISSIONING
PREPARATION
Commissioning of this unit should
only be car ried out by YORK Au tho -
rized per son nel.
The Millennium Microcomputer Con trol Sys tem
Op er at ing In struc tions must be read in con junc tion
with this sec tion.
PREPARATION – POWER OFF
The following checks should be made with the cus tom er
supply/supplies to the unit switched OFF.
Inspection
Inspect unit for installation dam age. If damage is found
take ac tion and/or repair as appropriate.
Refrigerant Charge
Units are normally shipped as stan dard with a full
re frig er ant operating charge. Check that refrigerant
pres sure is present in both systems and that no leaks
are ap par ent. If no pressure is present a leak test must be
un der tak en. The leak(s) should be located and re paired.
Re paired sys tems and units supplied with a ni tro gen
hold ing charge must be evacuated with a suit able vac-
uum pump/re cov ery unit as appropriate to be low 100
microns.
Do not liquid charge with static water in the evaporator.
Care must also be taken to liquid charge slowly to avoid
ex ces sive thermal stress at the charging point. Once the
vacuum is broken, charge into the condenser coils with
the full operating charge as given in the Technical Data
Section.
Valves
Open each compressor suction, economizer, and dis-
charge valve ful ly (counter-clockwise) then close one
turn of the stem to ensure operating pressure is fed to
the pres sure trans duc ers. Open the liquid line service
valve ful ly and en sure the oil re turn line ball valve is
open in each system.
Compressor Oil

voltage. After the tapping is veri ed, replace the lid.
Switch Settings
Ensure that the unit ON/OFF switch on the display door
and the micro board system switch es S2 through S5 are
set to “0” (OFF). Set the red han dled emergency stop
de vice on the options panel to “1” (ON). For units tted
with door interlocked circuit breakers the power panel
doors must be closed and the devices set to “1” (ON).
The customers power dis con nec tion devices can now
be set to ON.
The machine is now live!
The unit is tted with an under voltage circuit in each
pan el and it may take be tween 5 to 10 seconds for its
con tacts to close and energize the unit’s electronics,
in clud ing the dis play on the main panel.
Compressor Heaters
Verify the compressor heaters are en er gized. If
the ambient temperature is above 96°F (36°C) the
com pres sor heaters must be on for at least 8 hours before
start-up to ensure all refrigerant liquid is driven out of
the compressor. If the ambient tem per a ture is be low
86°F (30°C) then allow 24 hours.
Water System
Verify that the chilled liquid system has been installed
correctly, and has been commissioned with the correct
direction of water ow through the evaporator. The inlet
should be at the refrigerant pipework connection end of
the evaporator. Purge air from the top of the evaporator
using the plugged air vent mounted on the top of the
evaporator body. Flow rates and pressure drops must be
within the limits given in the Technical Data Section.
Op er a tion outside of these lim its is un de sir able and could
cause damage.
Flow Switch
Verify a chilled water ow switch is cor rect ly tted in
the customers pipework on the evaporator outlet, and
wired into the control panel correctly using shielded
cable. There should be a straight run of at least 5 pipe
di am e ters on either side of the ow switch. The ow
switch should be connected to terminals 13 and 14 in the
mi cro panel (Figs. 13 and 14, pages 40 and 41).
Temperature Sensor(s)
Ensure the leaving liquid tem per a ture sensor is coated
with heat conductive com pound (part no. 013-00890-
000) and is inserted in the water outlet sensor pocket
of the evaporator. This sensor also acts as the freeze
pro tec tion ther mo stat sensor and must always be in the
water OUTLET sen sor pocket.
Control Supply
Verify the control panel display is illuminated.
Programmed Options
Verify that the options factory programmed into the
Mi cro com put er Control Center are in accordance with
the cus tom ers order re quire ments by pressing the ‘Op-
tions’ key on the keypad and read ing the settings from

Commissioning
FIRST TIME START-UP
During the commissioning period
there should be suf cient heat load
to run the unit under sta ble full load
op er a tion to enable the unit con trols,
and sys tem op er a tion to be set up cor-
rect ly and a com mis sion ing log tak en.
Be sure that the Micro Panel is prop-
er ly pro grammed (page 166) and the
Sys tem Start-up Check list (page 117)
is com plet ed.
Interlocks
Verify that liquid is owing through the evaporator and
that heat load is present. Ensure that any remote run in-
ter locks are in the run position and that the run schedule
requires the unit to run or is overridden.
System Switches
Place the ‘Sys 1’ switch on the mi cro pro ces sor board to
the ‘ON’ position – (Fig. 46, page 130).
Start-up
Remove the locking device from the unit Auto/OFF
switch which prevents unauthorized starting of the unit
before commissioning. Press the ‘Status’ key, then turn
the unit switch to the “1” position to start the unit (there
may be a few seconds delay before the rst com pres sor
starts be cause of the anti-recycle timer). Be ready when
each com pres sor starts, to switch the unit OFF im me -
di ate ly if any unusual noises or other adverse con di tions
de vel op. Use the appropriate emergency stop de vice if
necessary.
Oil Pressure
When a compressor starts, press the rel e vant ‘System
Pressures’ key and verify that oil dif fer en tial pressure
develops immediately (Discharge Pressure minus Oil
Pressure). If oil pressure does not develop, the automatic
controls will shut down the compressor. Un der no cir-
cum stanc es should a restart attempt be made on a com-
pres sor which does not develop oil pres sure im me di ate ly.
Switch the unit switch to the ‘0’ po si tion (OFF).
Refrigerant Flow
When a compressor starts, a ow of liquid refrigerant
will be seen in the liquid line sight glass. After several
min utes operation and providing a full charge of re frig -
er ant is in the system, the bubbles will disappear and be
re placed by a solid column of liquid.
Fan Rotation
As discharge pressure rises, the con dens er fans op er ate
in stages to control the pressure. Verify that the fan op-
eration is correct for the type of unit.
Suction Superheat
Check suction superheat at steady full compressor load
only. Measure suction tem per a ture on the copper line
about 6" (150 mm) before the compressor suc tion ser-
vice valve. Measure suction pres sure at the com pres sor
service valve. Superheat should be 10°F to 12°F
(5.6°C to 6.7°C).
Expansion Valve
The electronic expansion valves are factory set and
should not need adjustment.
Economizer Superheat
(Not all models are equipped with economizers)
Check economizer su per heat at steady full com pres sor
load only, under conditions when the econ o miz er sole-
noid is energized. (See Section 1.22, page 134) Measure
gas tem per a ture on the econ o miz er outlet pipe next to the
ex pan sion valve bulb. Mea sure gas pressure at the back
seat port of the economizer ser vice valve. Su per heat as
measured should be 10°F to 12°F (5.6°C to 6.7°C).
Subcooling
Check liquid subcooling at steady full com pres sor
load only. It is important that all fans are run ning for
the sys tem. Measure liquid line temperature on the
copper line beside the main liquid line service valve.
Measure liq uid pressure at the liquid line service valve.
Subcooling should be 12°F to 15°F (6.7°C to 8.3°C).
No bubbles should show in the sight glass. If subcooling
is out of range add or re move re frig er ant as required.
Do not over charge the unit. The liq uid ow to the main
evaporator TXV is subcooled fur ther by the econ o miz er,
increasing subcooling to be tween 22°F and 28°F (12°C
and 15°C) at ambients above 90ºF.
General Operation
After completion of the above checks for System 1, stop
the unit, switch OFF the ‘SYS 1’ switch on the main
panel microprocessor board and repeat the pro cess for
each subsequent system. When all run cor rect ly, stop the
unit, switch all applicable switch es to the ‘ON’ po si tion
and restart the unit.

Op er a tion
GENERAL DESCRIPTION
The units are designed to work independently, or in
con junc tion with other equipment via a YORK ISN
build ing management system or other automated con-
trol sys tem. When operating, the unit controls monitor
the chilled liquid system temperature at the unit and
take the ap pro pri ate action to maintain this temperature
with in de sired limits. This action will involve running
one or more compressors at a suitable load step to match
the cool ing effect of the refrigerating systems to the
heat load on the liquid system. The heat removed from
the chilled liquid is then rejected from the air cooled
con dens er coils.
The following sections give an overview of the op er a tion
of the unit. For detailed information, reference should
be made to the Chiller Control Panel Pro gram ming and
Data Access Op er at ing In struc tions for the unit (pages
122 - 192).
START-UP
Check the main power supplies to the unit are ‘ON’, all
refrigerant service valves are open (counter-clockwise
one turn short of fully open) and chilled liquid ow has
been es tab lished (unless the unit chilled liquid pump
start con trol is being used, in which case just ensure
the pump supply is on). Ensure only the correct system
switches (SYS 1-2) on the microprocessor cir cuit board
are in the ‘ON’ position.
Press the ‘STATUS’ key on the keypad and then switch
the unit ON/OFF switch below the keypad to the ON
position.
The controller will perform a pre-check to ensure that
the daily/holiday schedule and any remote interlocks will
allow the unit to run, all safety cut-outs are sat is ed and
that cooling load is required (i.e. that the chilled liquid
temperature is outside the set limits). Any prob lems
found by the pre-check will be displayed if present. If
no prob lems are present and cooling duty is required the
lead compressor will start.
The display will show the anti-coincidence timer sta tus
for the lag compressor, followed by ‘NO COOL LOAD’
until it is called to operate by the control sys tem.
NORMAL RUNNING AND CYCLING
Once the unit has been started, all operations are fully
automatic. After an initial period at minimum capacity
on the lead compressor, the control system will adjust
the unit load depending on the chilled liquid tem per a ture
and rate of temperature change. If high heat load is pres-
ent, the controller will increase the capacity of the lead
compressor and/or start-up the other compressor.
If very little heat load is present, the lead compressor
will continue at minimum capacity or may simply stop
again to avoid overcooling the liquid. If the latter is the
case, one compressor will restart automatically should
the liquid temperature rise again.
Once a compressor is running, discharge pressure ris es
as refrigerant is pumped into the air cooled con dens er
coils. This pressure is controlled by stages of fans to
ensure maximum unit ef ciency while main tain ing suf-
cient pressure for correct operation of the con dens ers
and expansion valves.
When a compressor is running, the controller monitors
oil pressure, motor current, and various other system
parameters such as discharge pressure, chilled liquid
temperature, etc. Should any problems occur, the con trol
system will immediately take appropriate action and
display the nature of the fault (Section 8).
SHUTDOWN
The unit can be stopped at any time by switching the
UNIT ON/OFF switch just below the keypad to the
OFF po si tion. The compressor heat er will en er gize to
prevent refrigerant condensing in the com pres sor rotors.
If ambient tem per a tures are low, the evaporator heater
mats will also en er gize to pre vent the possibility of liq-
uid freezing in the ves sels. The mains pow er to the unit
should not nor mal ly be switched OFF, even when the
unit is not re quired to run.
The system switches (S2-S5) on the microboard can be
used to cycle a system OFF. An automatic pumpdown
will occur using the system switches.
If mains power must be switched OFF, (for extended
main te nance or a shutdown period), the compressor suc-
tion, discharge and motor cooling service stop valves
should be closed (clockwise) and if there is a pos si bil i ty
of liq uid freezing due to low ambient temperatures, the
evaporators should be drained. Valves should be opened
and power must be switched on for at least 8 Hours
(36 Hours if ambient temperature is over 86°F [30°C])
be fore the unit is restarted.

ELECTRICAL NOTES
NOTES:
1. Minimum circuit ampacity (MCA) is based on 125% of the rated load amps for the largest motor plus 100% of the rated load amps for all
other loads included in the circuit, per N.E.C. Article 430-24. If a Factory Mounted Control Transformer is pro vid ed, add the following to the
system #1 MCA values in the YCAS Tables: -17, add 15 amps; -28, add 12 amps; -40, add 7 amps; -46, add 6 amps; -58, add 5 amps.
2. The recommended disconnect switch is based on a minimum of 115% of the summation rated load amps of all the loads included in the circuit,
per N.E.C. 440 - 12A1.
3. Minimum recommended fuse size is based on 150% of the largest motor RLA plus 100% of the remaining RLAs. Minimum fuse rating = (1.5
x largest compressor RLA) + other compressor RLAs + (# fans x each fan motor FLA).
4. Maximum dual element fuse size is based on 225% maximum plus 100% of the rated load amps for all other loads included in the circuit, per
N.E.C. 440-22. Maximum fuse rating = (2.25 x largest compressor RLA) + other compressor RLAs + (# fans x each fan motor FLA).
5. Minimum recommended circuit breaker is 150% maximum plus 100% of rated load amps included in the circuit. Minimum circuit breaker rating
= (1.5 x largest compressor RLA) + other compressor RLAs + (# fans x each fan motor FLA).
6. Maximum circuit breaker is based on 225% maximum plus 100% of the rated load amps for all loads included in the circuit, per circuit, per
U.L. 1995 Fig. 36.2. Maximum circuit breaker rating = (2.25 x largest compressor RLA) + other com pres sor RLAs + ( # fans x each fan motor
FLA).
7. The Incoming Wire Range is the minimum and maximum wire size that can be accommodated by unit wiring lugs. The (1), (2), or (3) indicate
the number of termination points or lugs which are available per phase. Actual wire size and number of wires per phase must be determined
based on ampacity and job requirements using N.E.C. wire sizing information. The above recommendations are based on the National Electric
Code and using copper conductors only. Field wiring must also comply with local codes.
8. A ground lug is provided for each compressor system to accommodate eld grounding conductor per N.E.C. Article 250-54. A control circuit
grounding lug is also supplied. Incoming ground wire range is #6 - 350 MCM.
9. The eld supplied disconnect is a “Disconnecting Means” as de ned in N.E.C. 100.B, and is intended for isolating the unit from the available
power supply to perform maintenance and troubleshooting. This disconnect is not intended to be a Load Break Device.
10.Two-Compressor machines with single-point power connection, and equipped with Star (Wye)-Delta Compressor motor start must also include
factory-provided individual system circuit breakers in each motor control center. All 3 & 4 Compressor machines equipped with Star-Delta
com pres sor motor start must also include factory-provided individual system circuit breakers in each motor control center.
11. Consult factory for Electrical Data on units equipped with “High Static Fan” option. High Static Fans are 3.8 kW each.
12.FLA for “Low Noise Fan” motors: 200V = 8.0A, 230V = 7.8A, 380V = 4.4A, 460V = 3.6A, 575V = 2.9A.
13.Group Rated breaker must be HACR type for cU.L. Machines.

NOTES:
1. Placement on a level surface free of obstructions (including snow, for winter operation) or air recirculation ensures rated performance, reli-
able operation and ease of maintenance. Site re stric tions may compromise minimum clearances indicated below, resulting in un pre dict able
air ow patterns and possible diminished performance. YORK’s unit controls will optimize op er a tion without nuisance high pressure safety
cutout; however, the system designer must consider potential performance degradation. Access to the unit control center assumes the unit is
no higher than on spring isolators. Recommended minimum clearances: Side to wall - 2m; rear to wall - 2m; control panel end to wall - 1.2m;
top - no obstructions allowed; distance between adjacent units - 3m. No more than one adjacent wall may be higher than the unit.
