INSTALLATION
Storage
-- If the unit is to be stored for a period of time before installation or start-up, be sure to protect file machine
from construction
dirt. Keep protective shipping covers in
place until file machine is ready for installation.
Step 1 -- Inspect Shipment -- Inspect unit
for &image upon arrival. If &image is found, immediately file a claim
with the shipping company.
Step
2 --
Place,
Mount,
and Rig the Unit --
When considering a location for the unit, be sure to consult
NEC (National Electrical Code, U.S.A.) and/or local code
requirements. Allow sufficient space for airtlow, wiring, piping, and service. See Fig. 2-10.
NOTE: To facilitate refrigerant vent piping, all units have fusible plugs with 1/4 in. SAE (Society of Automotive Engineers)
flares and pressure reliefs with 3/4 in. NPT fittings (if required
by locfd codes).
PLACING UNIT--Ix_cate
the unit so that the condenser
airtlow is unrestricted both above fred on the sides of the unit.
Airflow find service clefuances me 6 fl (1.8 m) around file unit.
Acceptable clearance on the cooler connection side or sides or
ends without control boxes can be reduced to 3 ft (1 m) without
sacrificing
performance
as long as the remaining
three
sides me
unrestricted.
Acceptable
clearance
on the side wifll a control box
cfm be reduced
to 4 fl (1.3 m) due to NEC regulations,
without
sacrificing
performance
as long as the remaining
three sides am
unrestricted.
Provide ample room for servicing find removing
file

See Fig. 2-10 for lequimd
clemances.
Ix)cffl codes for
clem'ances
take precedence
over the manufacturer's
mcommenc_kLtions when locfd codes cfdl for greater clearances.
If multiple

RIGGING UNIT (See Fig. 12-14) --The
30XA080-500 units
are designed for overhead rigging and it is impollant that this
method be used. Holes are provided in frame base channels,
marked for rigging (see rigging label on unit). Field-supplied
shackles tue required to facilitate lifting. Secure the shackles
to the base rails at the points noted on the rigging label. See
Table 2 for the number of lifting points for each unit.
Do not use a forklift truck to move the units.
See Fig. 12-14 for rigging centers of gravity.
For shipping, some domestic units and all export units are
mounted on a wooden skid under entire base of unit. Skid can
be removed before unit is moved to installation site. Lift the
unit from above to lemove skid. See Fig. 12-14 for rigging
center of gravity. On export units, the top skid can be used as
the spreader baLs. If the unit was shipped with a shipping bag,
the bag must be removed to gain access to the rigging holes in
the base mil.

UNIT SIZE
NUMBER
OF LIFTING

If overhead rigging is not available, the unit can be moved
on rollers or dragged. When unit is moved on rollers, the unit
skid, if equipped, must be removed. To lift the unit, use jacks at
the rigging points. Use a minimum number of rollers to distribute the load such that the rollers are no more than 6 ll (1.8 m)
apart. If the unit is to be dragged, H1l the unit as described
above, and place unit on a pad. Apply moving force to the pad,
and not the unit. When in its I]mfl location, raise the unit and
remove the pad. If the unit was shipped with coil protection, it
must be removed before start-up. The shipping bag for export
units must be removed before start-up.

Step 3 -- Cooler Fluid and Drain Piping
nections -- See Fig. 15-18 for piping applications.
Con-
leaving water temperature stability for comfort cooling applications, a minimum of 3 gallons per ton (3.25 liters per kW) is
required on all unit sizes. For process cooling applications, applications where high stability is critical, or operation at mnbient temperatures below 32 F (0 ° C) is expected, the loop volume should be increased to 6 to 10 gallons per ton (6.46 to
10.76 liters per kW) of cooling. In order to achieve tiffs volume, it may be necessary to add a water storage tank to the water loop. If a storage tank is added to the system, it should be
properly vented so that the tank can be completely filled and all
air eliminated. Failure to do so could cause lack of pump stability and poor system operation. Any storage tank that is placed
in the water loop should have internal baffles to allow fllorough
mixing of the fluid. See Fig. 20.
Remove file chilled water flow switch, entering and leaving
water thermistors before welding connecting piping. Reinstall flow switch and thermistors after welding is complete.
Failure to remove these devices may cause unit &image.
GENERAL -- The factory-installed
victaulic connections _dlow clamp-on connection of water lines to file coolel_ in all
30XA units. A flow sensor is factory-installed in the side of the
entering fluid nozzle. See Fig. 19. See Table 3 for 30XA unit
operating range. See Fig. 16 for cooler option dimensions.
System Piping -- Proper system design and installation procedures should be followed closely. The system must be
constructed with pressure tight components
and thoroughly
tested for installation leaks.
DUAL CHILLER CONTROL -- The Co171/i_tTLinkTM controller allows 2 chillers (piped in parallel or series) to operate as
a single chilled water plant with standard control functions
coordinated through the master chiller controllec This stan&trd
Co_71ibrtLink feature requires a communication
link between
the 2 chillers.
There me severtd advantages
•
•
•
•
Installation of water systems should follow sound engineering practice as well as applicable local and industry standards.
Improperly designed or inst_dled systems may cause unsatisfactory operation and/or system failure. Consult a water
treatment specialist or appropriate literature for information
regarding filtration, water treatment, and control devices.
to this type of control:
redundancy (multiple circuits)
better low load control, (lower tonnage capability)
lower rigging lift weights (2 machines rather than one
large machine)
chiller lead-lag operation (evens the wear between the
two machines)
Parallel Dual Chiller Operation
-- Pm'allel chiller operation
is the recommended option for dual chiller control. In this case,
each chiller must control its own dedicated pump or isolation
valve. Balancing v_dves are recommended
to insure proper
flow in each chillec Two field-supplied and inst_dled dual chiller leaving water temperature sensors ale required, one for each
module for this function to operate properly.
Dual Chiller Leaving Water Sensor --If the Dual Chiller algorithm is used, and the machines me installed in parallel, a
dual chilled water sensor must be installed for each module. Install the well in the common leaving water headec See Fig. 17.
Consider adding additional isolation valves to isolate each
chiller to allow for service on a machine, and still allow for partied capacity from the other chillec See Fig 17.

the cooler head for maintenance.
[nst_dl pipe hangers where
needed. Make sum no weight or stress is placed on the water
nozzle.
Provide openings in fluid piping for pressure gages and
thermometel_ (if used). These openings should be 5 to 10 pipe
diameters from the unit leaving water nozzle. For thorough
mixing and temperature stabilization, wells in the leaving fluid
pipe should extend at least 2 in. (50 mm) into the pipe.
Although the cooler has an air vent, it is recommended
that
a field-supplied air vent be installed in the system to facilitate
servicing. Field-supplied shut-off and balancing v_dves should
also be installed to facilitate servicing and flow balancing.
Ix_cate valves in return and supply fluid lines as close to the
chiller as possible. Ix)cate air vent at highest point of the cooler
fluid system. See Fig. 15.
_
Provide diain connections at all low points to permit complete di'ainage of the system.
COOLER PUMP CONTROL--It
is recommended
that
cooler pump control be utilized on all chillers unless the chilled
water pump runs continuously or the chilled water system contains a suitable antifieeze solution. Proper configuration of the
cooler pump control is required to prevent possible cooler
fieeze-up. A thermal flow sensor is facto q inst_dled in the
entering fluid nozzle to prevent operation without flow through
the coolec See Fig. 21. The sensor contacts am facto U wired.
The factou-installed
flow sensor and cooler interlock must be
wired in series. Install TBS-I and TBS-2 if using a cooler pump
interlock and connect it to these terminals. It is also recommended that the chiller be interlocked with the chiller water
pump starter to provide additional freeze protection. See the
Field Control Power Connections section on page 34 for proper
connection of the cooler pump interlock. The cooler pump relay will remain energized for 30 seconds after all compressors
stop due to an off command. In the event a freeze protection
_flarm is generated, the cooler pump relay will be energized
whether the cooler pump control is configured to "ON" or
"OFF". The cooler pump relay is also energized anytime a
compressor is started and when certain _dmms are generated.
The cooler pump relay should be used as an override to the external pump control if cooler pump control is not utilized.

BRINE UNITSSpecial factory modifications
to the units
are required to _dlow them to operate at fluid temperatures less
than 34 F (1.1 C). Be sure that the fluid has sufficient inllibited
glycol or other suitable corrosion-lesistant
antitYeeze solution
to prevent cooler freeze-up.
Mount the smaller height baffle on units with a control box
located on the end of the unit. It is recommended that the upper
notches be used for mounting the baffles. This reduces the risk
of dmnaging the coil while drilling a mounting hole. Ix_osen
the upper comer post bolts and slide the baffle under the bolt
and washel: Tighten the bolt. Drill holes in the bottom of the
flange of the baffle and mount with two sclews to secure the
bottom of the baffle to the comer post. Repeat the process for
the opposite end. See Fig. 22.
WATER TREATMENTUntleated or improperly tleated
water may result in corrosion, sc_ding, erosion, or algae. The
services of a qu_dified water tleatment specialist should be
obtained to develop and monitor a treatment program.
PREPARATION
FOR WINTER SHUTDOWN
-- If the unit
is not operatiomfl during the winter months, at the end of cooling season complete the following steps.
Water must be within design flow limits, clean, and treated
to ensure proper chiller performance and reduce the potential of tube damage due to corrosion, scaling, erosion, and
algae. Cmrier assumes no responsibility for chiller &_mage
resulting from untreated or improperly treated watel:
Failure to remove power before draining heater equipped
coolers can result in heater tape and insulation damage.
1. [f the cooler will not be dndned do not shut off power
disconnect during off-season shutdown. If the cooler is
drained, open the circuit breaker for the heater. CB-HT
(circuit breaker heater) or shut off power during offseason shutdown.
NOTE: Do not use automobile anti-freeze, or any other fluid
that is not approved for heat exchanger duty. Only use appropriately inhibited glycols, concentrated
to provide adequate
protection for the temperature considered.
PREPARATION
FOR YEAR-ROUND
OPERATION
-- In
areas where the piping or unit is exposed to 32 F (0 ° C) or
lower ambient temperatures,
freeze-up protection is required
using inhibited glycol or other suitable corrosion-resistant
antifleeze solution and electric heater tapes. Heater tapes on piping
should have a rating for ;u'ea mnbient temperatures and be covered with a suitable thickness of closed-cell insulation. Route
power for the heater tapes from a sepm'ately fused disconnect.
Mount the disconnect within sight from the unit per local or
NEC (National Electric Code) codes. Identify disconnect at
heater tape power source with a warning that power must not
be turned off except when servicing unit.
2.
Draining the fluid from the system is highly recommended.
3.
Isolate the cooler from the rest of the system with water
shutoff v_dves.
4.
Completely fill the cooler with a mixture of half water
and half inhibited glycol solution (or other suitable conosion-inhibitive
antifreeze) for 15 ° F (8.3 ° C) below the
expected low ambient temperature conditions.
Leave the cooler filled with the antifreeze solution for the
wintel: or drain if desired. Be sure to deenergize heaters
(if installed) as explained in Step 1 to plevent damage.
Use an approved method of disposal when lemoving antifreeze solution.
5.
IMPORTANT:
Adding antifreeze solution is the only
certain means of protecting the unit flom freeze-up if
heater fails or electrical power is interrupted
or lost
while temperatures
are below 32 F (0 ° C).
6. At the beginning of the next cooling season, be sure that
there is refrigerant
pressure on each circuit before
refilling coolel: add recommended inhibitol: trod reset the
CB-HT (circuit breaker heater) (if opened) or restore
powel:
IMPORTANT:
Before starting the unit, be sure all of
the air has been purged from the system.
Step 4 --
A di'ain connection is located at the bottom of the cooler
head. See Fig. 2-10 for connection location. Install shut-off
v_dves to the drain line before filling the system with fluid.
Make Electrical
Connections
Electrical shock can cause personal injury and death. Shut
off _fll power to this equipment during inst_fllation. There
may be more than one disconnect switch. Tag all disconnect locations to alert othel_ not to restore power until work
is completed.
Low Ambient Temperature
Head Pressure Control -- If the
unit is equipped with the low ambient temperature head pressure control option, field-fabricated
and field-installed
wind
baffles are required if the wind velocity is anticipated to be
gleater than 5 mph (8 km/h). Two different baffles may be required, facing the control box. Wind baffles should be constmcted with minimum 18-gage g_dvanized sheet metal or other suitable corrosion-resistance
material with cross breaks for
strength. See Fig. 22. Use field-supplied screws to attach baffles to the corner posts of the machine. Be sure to hem or turn a
flange on _dl edges to eliminate sharp edges on the baffles.
POWER SUPPLY --The
electrical ch_u'acteristics
of the
available power supply must agree with the unit nameplate
rating. Supply voltage must be within the limits shown. See
Tables 4-6 for electric_d and configuration &tta.
To avoid possibility of electric_d shock, open all disconnects before installing or servicing this accessory.
FIELD POWER CONNECTIONS
(See Fig. 23) -- All power wiring must comply with applicable
local and national
codes. Install field-supplied, branch circuit lhsed disconnect(s)
of a type that can be locked off or open. Disconnect(s) must be
located within sight and readily accessible from the unit in
compliance with NEC Article 440-14 (U.S.A.). See Tables 4
and 5 for unit electrical &_ta. See Table 6 for compressor and
fan electrical &tta.
To avoid dmnage to the refl'igerant coils and electrical components, use extreme ctue when drilling screw holes and
screwing in fasteners.
IMPORTANT:
The 30XA units have a factory-inst_dled
option available for a non-fused disconnect for unit power
supply. If the unit is equipped with this option, all field
power wiring should be made to the non-fused disconnect
since no terminal blocks are supplied.

4. Wiring for main field supply must be rated 75 C minimum. Use copper for all units.
a. Incoming wire size range for the terminal block is no. 4 AWG (American Wire Gage)
to 500 kcmil.
b. Incoming wire size range of non-fused disconnect with MCA up to 599.9 amps is
3/0 to 500 kcmil.
c. Incoming wire size range of non-fused disconnect with MCA from 600 to 799.9 amps
is 1/0 to 500 kcmil.
d. Incoming wire size range o1non-fused disconnect with MCA from 800 to 1199.9 amps
is 250 kcmil to 500 kcmiL
5. Data provided circuit I/circuit 2 where there are two circuits.
NOTES:
1. Units are suitable for use on electrical systems where voltage supplied to the unit
terminals
is not below or above the listed minimum and maximum limits. Maximum
allowable phase imbalance is: voltage, 2%; amps 10%.
2. Cooler heater is wired into the control circuit so it is always operable as long as the
control power supply disconnect is on, even if any safety device is open.
3. For MCA that is less than or equal to 380 amps, 3 conductors are required.
For MCA between 381-760 amps, 6 conductors are required.
For MCA between 761 -1140 amps, 9 conductors are required.
For MCA between 1141-1520 amps, 12 conductors are required.
Calculation of conductors
required is based on 75 C copper wire.

COMMUNICATION
BUS WIRING (See Fig. 24) -- The communication
bus wiring
is a shielded, 3-conductor cable wifll &'ain wire and is field
supplied and instCdled in the field.
3. Connect the red wire to (+) terminal on TB3 of the plug,
the white wire to COM terminal, and the black wire to the
(-) terminal.
4. The RJI 4 CCN connector on TB3 can also be used, but is
only intended for temporary connection (for example, a
laptop computer running service tool).
The system elements tue connected to the communication
bus in a &fisy chain arrangement.
The positive pin of each
system element communication
connector must be wired to the
positive pins of the system elements on either side of it. This is
also required for the negative and signal ground pins of
each system element. Winng connections for CCN (Carrier
Comfort Network) should be made at TB (terminal block) 3.
Consult the CCN Contractor's Manual for further information.
See Fig. 24.
NOTE: Conductors
and &'ain wire must be 20 AWG
(American Wire Gage) minimum
stranded, tinned coppel:
Individual conductors
must be insulated with PVC, PVC/
nylon, vinyl, Teflon, or polyethylene. An aluminum/polyester
100% foil shield and an outer jacket of PVC, PVC/nylon,
chrome vinyl, or Teflon with a minimum opemfing temperature range of-4 F (-20 C) to 140 F (60 C) is required. See
Table 7 for a list of manufacturers
that produce CCN bus
wiring that meet these requirements.
Table 7 -- CON Communication
IMPORTANT:
A shorted CCN bus cable will prevent
some routines from running and may prevent the unit
from starting. If abnormal conditions occur, disconnect
the machine from the CCN. If conditions
return to
normal, check the CCN connector and cable. Run new
cable if necessary. A short in one section of the bus
can cause problems with all system elements on the
bus.
NON-CCN COMMUNICATION
WIRING -- The 30XA units
offer severtd non-CCN translatoL's. Refer to the separate installation instructions for additional wiring steps.
FIELD CONTROL
OPTION WIRING -- Install field control
wiring options. Some options, such as 4 to 20 mA demand
limit that requires the Energy Management
Module, may
require that accessories
be installed first (if not factory
installed) for terminal connections.
DUAL CHILLER LEAVING WATER SENSOR --If the dual
chiller algorithm is used and the machines are installed in parallel, an additional chilled water sensor must be installed for
each chillec Install the wells in the common leaving water
header See Fig 25. DO NOT relocate the chiller's leaving
water thermistoLs. They must remain in place for the unit to
operate properly.
The thermistor well is a 1/4 in. NPT fitting for securing the
well in the piping. The piping must be drilled and tapped for
the well. Select a location that will allow for removal of the
thermistor without any restrictions.

it is important when connecting to a CCN communication
bus that a color coding scheme be used for the entire network
to simplify the installation. It is recommended that red be used
for the signal positive, black for the signal negative, and white
for the signal ground. Use a similar scheme for cables containing different colored wires. At each system element, the shields
of its communication
bus cables must be tied togethel: If the
communication
bus is entirely within one building, the resulting continuous shield must be connected to a ground at one
point only. If the communication
bus cable exits from one
building and enters another, the shields must be connected to
grounds at the lightning suppressor in each building where the
cable enters or exits the building (one point per building only).
To connect the unit to the network:
Once the well is inserted, install the thermistors. Insert the
thermistor into the well until the o-ring reaches the well body.
Use the nut on the thermistor to secure the thermistor in place.
Once the thermistor is in place, it is recommended
that a
thermistor wire loop be made and secured with a wire tie to the
chilled water pipe. See Fig. 26.
For dual chiller control a CCN bus must be connected
between the two modules. See the Carrier Comfort Network
Communication
Bus Wiring section for additional information.
1. Turn off power to the control box.
2. Cut the CCN wire and strip the ends of the red (+), white
(ground), and black (-) conductors. Substitute appropriate colors for different colored cables.
