YORK Millennium®
OVERVIEW
Introducing the YORK Millennium 25, 30, & 40 ton rooftop
line - units designed to provide peak performance and value
both today and for years to come. When we asked our cus-
tomers what they wanted in a new rooftop line, we were care-
ful to listen to both the needs of today and tomorrow. So,
you'll find that Millennium units not only help you solve
today's problems, but can handle tomorrow's difficulties as
well:
Industry Leading Efficiency - The Millennium with EER rat-
ings of up to 10.5 make it the most frugal energy consumer in
its class. When it comes to lower operating costs, Millennium
simply outperforms the competition.
Double Wall Construction - Millennium units come double
walled as standard. The galvanized sheet metal liner pro-
vides the best protection against microbial growth, helping
both the unit and the indoor air stay fresh and clean. And, the
rigid sheet metal inner liner keeps the insulation completely
out of the air stream, eliminating concerns about fiberglass
particles.
Drain Pan Whisks Away Condensate - Condensate is fre-
quently the source of microbial contamination. Competitive
drain pans often are insufficiently sloped to properly drain all
of the condensate, causing drain pan corrosion and bacterial
growth to begin almost immediately. The YORK design is
sloped at the 1/4” per foot recommended by the ASHRAE
62.1-2004 ventilation draft standard, with an extra large drain
connection capable of removing up to three gallons of con-
densate per minute. It is available in either powder coat
painted steel or stainless steel for long life.
Efficient, Durable Scroll Compressors - The Millennium
design uses industrial grade hermetic scroll compressors for
peak efficiency and low noise operation. The compressor
design is so durable that it can actually hold more liquid
charge without slugging than is present in each refrigerant
circuit at shipment, dramatically reducing the chances of ever
slugging a compressor with liquid charge.
Multiple Refrigeration Circuits for Greater Turndown - The
YORK Millennium unit has intertwined circuits giving the best
unloading capability in the industry. With more and more
designs requiring higher outside air quantities, the lower
capacity capability is an outstanding way to neutralize outside
air without over-conditioning the space on off-peak days.
And, Millennium's high quality balance-port thermal expan-
sion valves are more effective at metering refrigerant flow in
part-load conditions, making Millennium a peak-performer
across a wide capacity range.
FEATURES AND BENEFITS
When it comes to flexibility, Millennium really shines. Our cus-
tomers were clear about one thing - not all installations are
the same. Some have very simple needs, others are more
involved. The YORK Millennium serves both markets - and all
of those in between - extremely well. YORK engineers crafted
a design which is both uniquely flexible and competitive, giv-
ing you the best of both worlds. In addition to a competitive
base product, Millennium offers unparalleled flexibility.
Optional features include:
Variable Air Volume - YORK gives you the ability to vary air
volume by inlet guide vanes or variable frequency drive - the
choice is yours. All Millennium VAV units come standard with
hot gas bypass to give extended operation range.

Optional Head Pressure Control - For those applications
where mechanical cooling is required below 40°F, optional
low ambient operation allows compressor operation down to
0°F.
Easily Upgrade Motor Efficiency to Meet Tighter Codes -
Optional high efficiency motors help you make simple
upgrades to meet more demanding building and energy
codes.
Enhanced Filtration Options - Millennium gives designers the
flexibility to meet various IAQ requirements with a full range
of rigid and throwaway filters at different efficiency levels.
Vibration Isolation - The Millennium's neoprene mounts are
typically sufficient for most applications but when sound and
vibration transmission are a major concern, YORK offers 1"
and 2" isolation springs for even greater protection from sup-
ply air fan noise and vibration.
Corrosion Resistant Coils- Many industrial and seacoast
applications require enhanced protection from corrosive envi-
ronments.
Optional TechniCoated Coated Condenser and Evapo-
rator Coils - Many industrial and seacoast applications
require enhanced protection from corrosive environ-
ments. The special dipped phenolic coating process
provides a high level of protection for the exposed con-
denser coil.
Optional Copper-Copper Condenser and Evaporator
Coils - For corrosion resistance.
Variety of Exhaust Air Options - YORK Millennium offers a
wide variety of exhaust air options, including barometric
relief, non-modulating power exhaust, and modulating power
exhaust. And, because Millennium units use forward-curved
blowers for power exhaust fans, they can exhaust up to 100%
of the nominal supply air at much greater static pressure
loads than competitive units. Not available on end return.
NOTE: In most applications, the supply fan will keep the
return at negative pressure. A barometric relief will
function better when ducted to building space, not
the return.
Optional Factory Installed Economizers - Millennium units
offer economizers with Standard or Optional low leak damp-
ers. Comparative enthalpy, single enthalpy and dry bulb con-
trol are available.
Optional Factory Installed Disconnect - A conveniently
located actuator handle in the front of the unit can disconnect
line power to the entire unit, eliminating the need for a field
provided disconnect. The handle may also be locked in either
position through the use of a standard padlock. Millennium's
single point power connection makes this option particularly
appealing. If desired, the disconnect may be ordered with a
115 volt, GFCI protected convenience outlet, including a fac-
tory wired transformer to power the outlet from the single
point power connection; the convenience outlet remains
operational when the disconnect is open.
Heating Done Your Way - Millennium offers the choice of nat-
ural gas standard or modulating gas heat, electric resistance
heat, hot water heat, steam, or no heat at all. Very simply, the
choice is yours.
INSTALLATION FEATURES
With YORK Millennium, high performance doesn't mean high
complexity. YORK listened carefully to make sure that Millen-
nium was as simple as possible, and service convenience
comes standard with each unit. From a single curb size to the
easy service access, you'll find that Millennium was designed
to be easy from start to finish.
Full Range of Air Flows and Static Pressures - The Millen-
nium design gives a complete offering of supply air flows and
static pressure combinations to meet most every application
requirement.
Single Power Point Connection - Millennium units have a sin-
gle gas and electric connection, minimizing time at the job
site. For further installation flexibility, power and gas connec-
tions may be brought up from the curb or through the side of
the unit.
Simple Controls - Millennium's controls system is easy to
understand and apply, and it doesn't lock you into proprietary
devices. A choice for YORK Millennium today does not limit
your choices tomorrow.
Rain Hoods Rotate Into Place - No bulky, field--installed rain
hoods here. Millennium rain hoods ship rotated inside the
unit. Once on the job, installer merely rotates the hood
upward and puts in a few screws - an easy one-person job.
Excellent Access for Service - Service access on Millennium
is a snap. Hinged and latched doors give access on both
sides of the unit to all major components. All doors have pos-
itive action slide latches for even greater ease of access. All
service fittings are conveniently located to minimize time and
effort.

CONSTRUCTION FEATURES
YORK's Millennium rooftop line is built for the long haul, with
high end features and construction offered at a competitive
price. Millennium units are manufactured at an ISO 9001 reg-
istered facility, and each rooftop is completely computer-run
tested prior to shipment. Some of the valuable construction
features of the Millennium which are not found on competitive
units include:
Double Wall Construction - Each unit has both an exterior
and an interior wall, which make for a more rigid design with
panels and doors that are solid, not flimsy. The unit features a
fully framed construction for even greater stability.
Powder Paint - Industry leading 1000 salt spray hour paint
keeps the unit in great condition for years to come.
Low Profile - Millennium units stand only 64” above their
curb, minimizing potential aesthetic conflicts.
Extended flue connection - Each gas unit ships with a field
mounted external flue. The flue lifts all products of furnace
combustion far above the unit - eliminating the possibility of
corrosion in the furnace heat exchanger from recirculating
flue gases.
Protective Covering - Special polyurethane sleeves which
cover the distributor tubing keep distributor tubes from con-
tacting each other and wearing out.
Built-in Hail Guard - Condenser coils angled at 30 degrees
from the vertical are inherently protected from damage due to
shipment, hail, etc.
Induced Draft Furnace - This design provides a positive
exhaust of all combustion products.

SELECT UNIT:
1. Determine nominal tons:
460,000 / 12,000 = 38.33 Tons
Thus, a nominal 40 ton unit is selected.
2. Reference Cooling Capacity Table for a 40 ton unit.
a. Locate the table for the 40 ton evaporator coil with
95° F air on the condenser.
b. Enter table at 13,000 CFM and 67°F WB air on
evaporator
c. Trace to 83° F Entering Dry Bulb column.
d. Read 493 MBH total capacity and 403 MBH sensi-
ble capacity.
The 40 ton unit will meet the cooling requirements. From
the nomenclature, the unit will be a Z34. Choose the
appropriate configuration for the next digit. Assuming
bottom return and supply, the fourth digit would be an
“A,” making the model Z34A.
3. Find Gas Heating Capacity Table.
a. Trace down Output column.
b. Find output which exceeds 320,000 Btuh require-
ment. The N5 option gives 426 MBH output.
c. Ensure that it is offered in the Z34 unit. Read option
model as N5.
From the basic nomenclature, the model now becomes
Z34AN5. Add voltage code of “4” for 460-3-60. Nomen-
clature becomes Z34AN44.
SELECT FAN SPEED AND HORSEPOWER
REQUIREMENTS OF SUPPLY AIR FAN
1. Find Supply Air Performance Tables for the 40 ton unit.
a. Check footnotes and make necessary additions or
deductions to static resistance of ductwork:
Ductwork static resistance 1.25 IWG
Economizer static resistance addition (interpolate) =.25
IWG + Gas Heat (High) = 0.5 IWG
Total Static Resistance 2.0 IWG
b. Enter Fan Performance Table at 13,000 CFM and
2.0 IWG static pressure:
RPM = 733
BHP = 11.8
NOTE: Either Class I or Class II blower could be used.
c. Enter the Fan Motor Drive Tables. Selecting a 15 hp
motor allows (service factor of 1.5) for a maximum
operating BHP greater than the 11.8 BHP require-
ment.
SIZE OVERCURRENT PROTECTION DEVICE AND
DETERMINE CIRCUIT AMPACITY
1. Find electrical tables for the basic 40 ton unit.
a. Enter table for 460-3-60 voltage.
b. Find 15 hp in the Supply Air Fan column.
c. Trace to Minimum Circuit Ampacity column - read
105.
d. Trace to Max. Fuse/Breaker Size column - read 125
amps.
e. Size wire and overprotection device accordingly.
f. Check all footnotes.

HOT WATER HEATING1
The YORK Millennium Rooftop units (30 - 40 Ton sizes) can
be furnished with a YORK hot water coil as the source of heat
(Bottom Supply Only). A one or two row coil will be factory
installed in the heating section downstream of the supply air
fan and just above the supply air opening in the bottom of the
unit.
The hot water control valve will not be provided. The installer
will need to field supply a water valve. The installer must also
connect the hot water piping, and valve wiring at the job site
for the hot water heat section to be operational.
For all hot water coils the entering water temperature should
not exceed 200°F.

STEAM HEATING
The YORK Millennium units (25, 30, and 40 ton sizes) can be
manufactured with a steam heat coil (Bottom Supply only).
YORK's one row steam coil is installed in the heating section
just downstream of the supply air fan and just above the sup-
ply air opening in the bottom of the unit.
The steam control valve will not be provided. The installer will
need to field supply a steam control valve. Connect the steam
piping and valve power wiring at the job site for the steam
heat section to be operational.
There are no provisions in the coil or control sequence to pre-
vent freezing of condensate. The control valve, piping and
field installed wiring connections are particularly vulnerable
because they are installed in the vestibule outside of the con-
ditioned air stream.
All piping, control valves, and wiring that is field installed must
conform to all local and national codes
Condensate can freeze on the control valve and piping if they
are not properly insulated.

SUPPLY AIR DRIVE ADJUSTMENT
At unit start-up, the measured CFM may be higher or lower
than the specified CFM shown in Figures 22, 23, and 24. To
achieve the specified CFM, the speed of the drive may have
to be decreased or increased by changing the pitch diameter
(PD) of the motor sheave as outlined below:
Example:
A 30-ton unit was selected to deliver 12,000 CFM with a 20
HP motor and a 856 RPM drive, but the unit is only delivering
11,000 CFM per Figure 23.
Use the equation to determine the required PD for the new
motor sheave (12,000 CFM / 11,000 CFM) x 6.7” = 7.31”.
Use the 30 ton table to select a Browning 2B5V74 which will
increase the speed of the unit’s drive and its supply air CFM
to 111.9%. Thus select the 7.5” PD at 112% increase over
standard.
New drive speed = 1.119 x 856 = 957.9 RPM
New supply air = 1.119 x 11,000 = 12,309 CFM
Re-use the existing belts and blower sheave.
New motor BHP = (speed increase)3 x estimated motor
BHP at original start-up with 11,000 CFM and 856 RPM =
(1.119)3 x 11 BHP = 1.4012 x 11 BHP = 15.41 BHP New
motor amps = (speed increase)3 x measured motor amps
at original start-up with 11,000 CFM and 856 RPM.
Failure to properly adjust the total system air quan-
tity can result in extensive blower damage.
Before making any blower speed changes review
the installation for any installation errors, leaks or
undesirable systems effects that can result in loss
of air flow.
Even small changes in blower speed can result in
substantial changes in static pressure and bhp.
Bhp or amp draw of the blower motor will increase
(see table) by the cube ratio of the blower speed.
Static pressure will increase by the square ratio of
the blower speed. Tables 26, 27 and 28 are for ref-
erence only. All blower speed changes must be
made by qualified personnel with strict adherence
to the fan laws.

1. These capacities are gross ratings. For net capacity, deduct the supply air blower motor heat (MBH = 3.415 x kW). Refer to the appropriate Blower
Performance Table for the kW of the supply air blower motor.
2. These ratings include the condenser fan motors and the compressor motors but not the supply air blower motor.

CFM, STATIC PRESSURE, AND POWER - ALTI-
TUDE AND TEMPERATURE CORRECTIONS
The information below should be used to assist in application
of product when being applied at altitudes at or exceeding
1000 feet above sea level.
The air flow rates listed in the standard blower performance
tables are based on standard air at sea level. As the altitude
or temperature increases, the density of air decreases. In
order to use the indoor blower tables for high altitude applica-
tions, certain corrections are necessary.
A centrifugal fan is a "constant volume" device. This means
that, if the rpm remains constant, the CFM delivered is the
same regardless of the density of the air. However, since the
air at high altitude is less dense, less static pressure will be
generated and less power will be required than a similar
application at sea level. Air density correction factors are
shown in Table 34 and Figure 21.
The examples below will assist in determining the airflow per-
formance of the product at altitude.
Example 1: What are the corrected CFM, static pressure,
and BHP at an elevation of 5,000 ft. if the blower performance
data is 6,000 CFM, 1.5 IWC and 4.0 BHP?
Solution: At an elevation of 5,000 ft the indoor blower will still
deliver 6,000 CFM if the rpm is unchanged. However, Table
34 must be used to determine the static pressure and BHP.
Since no temperature data is given, we will assume an air
temperature of 70°F. Table 34 shows the correction factor to
be 0.832.
Corrected static pressure = 1.5 x 0.832 = 1.248 IWC
Corrected BHP = 4.0 x 0.832 = 3.328
Example 2: A system, located at 5,000 feet of elevation, is to
deliver 6,000 CFM at a static pressure of 1.5". Use the unit
blower tables to select the blower speed and the BHP
requirement.
Solution: As in the example above, no temperature informa-
tion is given so 70°F is assumed.
The 1.5" static pressure given is at an elevation of 5,000 ft.
The first step is to convert this static pressure to equivalent
sea level conditions.
Sea level static pressure = 1.5 / .832 = 1.80"
Enter the blower table at 6000 sCFM and static pressure of
1.8". The rpm listed will be the same rpm needed at 5,000 ft.
Suppose that the corresponding BHP listed in the table is 3.2.
This value must be corrected for elevation.
BHP at 5,000 ft = 3.2 x .832 = 2.66

GUIDE SPECIFICATIONS - YORK
MILLENNIUM 25, 30, & 40 TON UNITS
GENERAL
Units shall be manufactured by Johnson Controls Unitary
Products in an ISO 9001 certified facility. Introducing the
YORK Millennium 25, 30, & 40 ton rooftop line - units
designed to provide peak performance and value both today
and for years to come. Millennium units are manufactured at
an ISO 9001 registered facility, and each rooftop is com-
pletely computer-run tested prior to shipment. The Millennium
is designed to be flexible enough to meet your needs today
and in the future. The true value of York's Millennium is that it
can be designed to fit any need, from cooling only, constant
volume applications to variable air volume systems with vari-
able frequency drive.
DESCRIPTION
Supply York Millennium packaged rooftop system in accor-
dance with the capacities in the plans. Units shall be rated by
the manufacturer at a minimum 10.0 EER according to AHRI
360. Units shall be shipped in a single package, fully charged
with R-410A refrigerant. The manufacturing facility shall be
registered under ISO 9001 Quality Standards for Manufactur-
ing. Units shall carry both ETL and CGA safety approval rat-
ings. Tags and decals to aid in the service or indicate caution
areas shall be provided. Installation and maintenance manu-
als shall be supplied with each unit. Units shall be capable of
providing mechanical cooling down to 40°F (0°F with low
ambient kit). Unit shall be capable of starting and running at
125°F. Unit electric and gas connections shall be either
through the curb or the side of the unit.
CONSTRUCTION
Base
The base rail shall be constructed of 12 gauge galvanized
steel, extending the full perimeter of the unit. All components
shall be supported from the base, and the base shall include
integral lifting lugs. The unit base rail shall overhang the roof
curb for water runoff and shall have a fabricated recess with a
continuous flat surface to seat on the roof curb gasket, pro-
viding a positive, weather tight seal between the unit and the
curb.
Casing
The unit cabinet shall be double wall construction to provide
both maximum resistance to bacterial growth in the air stream
and superior structural integrity. All sheet metal shall be G90
mill galvanized sheet metal, formed and reinforced to provide
a rigid assembly. Sheet metal shall be cleaned in an alkaline
and zinc phosphate bath, and the exterior surfaces shall be
coated with a 1.5 mil powder paint, capable of withstanding
1000 salt spray hours in accordance with ASTM B-117. The
unit shall be insulated with 1-1/2," 1 pound fiberglass insula-
tion between the two sheet metal skins. Insulation shall meet
NFPA-90A regulations for smoke and flame spread ratings.
The cabinet corner post and the intermediate side supports
shall be 16 gauge steel. All access doors shall be 18 gauge
on the exterior surfaces, and 20 gauge on the interior. Floor
shall be 18 gauge, and 24 gauge. All serviceable sections
shall have hinged access doors with latches on both sides of
the unit. All access doors shall be constructed of 20 gauge
steel on the outside, with 24 gauge on the inside. Each door
shall seal against a rubber gasket to prevent air and water
leakage. The roof shall be double wall, with 18 gauge on the
external surface and 24 gauge on the interior. The roof shall
be formed with a 45 degree drip lip overhanging the sidewalls
to prevent precipitation drainage from streaming down the
side of the unit. Roof sections shall be connected together via
integral channels fastened with screws and sealed with rub-
ber gasketing. Each fastened seam shall be further protected
by a sheet metal channel covering the full length of the gas-
ket surface, making a completely water tight seal.
SUPPLY AIR SYSTEM
SUPPLY AIR FAN
Fans shall be centrifugal type - Class I or Class II, statically
and dynamically balanced in the factory. Fan wheels shall be
designed for continuous operation at the maximum rate of fan
speed and motor HP. The fan and motor assembly shall be
mounted on a common base to allow consistent belt tension
with no relative motion between the fan and motor shafts.
The entire assembly shall be isolated from the unit base with
(optional 1”, 2" deflection springs or rubber isolators). The fan
discharge shall be connected to the cabinet through a rein-
forced neoprene flexible connection to eliminate vibration
transmission from the fan to the unit casing. Fans shall be
double-width, double-inlet with forward curved blades.
OPTIONAL
On variable air volume units without variable frequency
drives, fans shall be provided with heavy gauge, corrosion
resistant blades, with zinc-plated steel inter-locking operating
mechanism. Both inlet vanes must operate from a single
shaft and be synchronized for precise control.
Units equipped with variable frequency drive on supply fan
must be controlled by a duct static transducer providing a 2-
10 VDC signal to the drive. Supply fan variable frequency
drives shall have factory option of being equipped with a
manual drive bypass.
BEARINGS AND DRIVES
Bearings shall be self-aligning pillow-block re-greasable ball
bearings with an average life expectancy of 200,000 hours.
Grease fittings shall be accessible through access doors. Fan
motors shall be NEMA designed, Standard efficiency (option,
Hi-efficiency) ball bearing type with electrical characteristics
246837-YTG-L-1012
76 Johnson Controls Unitary Products
and horsepower as specified. Motors shall be 1750 RPM,
open drip proof type. The motor shall be located within the
unit on an adjustable, heavy steel base. All fan motor drives
shall be selected for a minimum service factor of 1.2 and
have fixed pitched sheaves.
AIR FILTERING SYSTEM
All filter holding frames shall be of heavy duty construction
designed for industrial applications. All filters shall be either
side accessible or front loading with access doors provided
on both sides of the filter section. All filter media shall be
Class II listed under UL Standard 900. Filter efficiencies shall
be rated in accordance with ASHRAE Standard 52-76 2"
Throwaway Filters with fiberglass media multiple shall be
standard
OPTIONAL
Two inch pleated, throwaway filters with 30% efficiency. Rigid
filters shall be high performance, expanded area, disposable
type filters. Rigid filter sections shall be preceded by a 2
throwaway prefilter assembly. Filter efficiency shall be 95%
(Option: 65%) based on ASHRAE Standard 52-76.
AIR INLET SYSTEM
General
Outside Air inlet openings shall be covered by a factory
installed rain hood permanently attached to the cabinet to
prevent windblown precipitation from entering the unit. The
rain hoods on the front and back of the unit shall be rotated
into the cabinet and secured for shipment so that upon instal-
lation they need only be rotated upwards and screwed into
place. The outside air hood shall contain a removable and
cleanable filter with an efficiency rating of 50% based on
ASHRAE 52- 76. All damper assemblies shall be of low leak
design. Damper blades shall be fabricated from a minimum of
16 gauge galvanized steel. Blade ends and edges shall be
