YORK Millennium
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.
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:
Multiple Refrigeration Circuits for Greater Turndown - The
YORK Millennium unit has intertwined 10 ton circuits (12.5
ton circuits on the 25 ton) - giving the best unloading capabil-
ity 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-con-
ditioning the space on off-peak days. And, Millennium's high
quality balance-port thermal expansion valves are more
effective at metering refrigerant flow in part-load conditions,
making Millennium a peak-performer across a wide capacity
range.
Industry Leading Efficiency - The Millennium's 9.5 EER (10
EER 25 ton) rating makes it the most frugal energy consumer
in its class. When it comes to lower operating costs, Millen-
nium 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.
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:
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.
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.
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.
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.
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.
Corrosion Resistant Coils- Many industrial and seacoast
applications require enhanced protection from corrosive envi-
ronments.
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.
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.
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.
Optional Copper-Copper Condenser and Evaporator
Coils - For corrosion resistance.
High Capacity Evaporator Coils - For those applications
which require slightly more capacity than offered by the stan-
dard Millennium product, YORK offers the option of higher
capacity evaporator coils, boosting cooling output without
increasing unit size. (30 & 40 Ton R-22 only)
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.
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.
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.
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.
Excellent Access for Service - Service access on Millennium
is a snap. Hinged and latched door options give access on
both sides of the unit to all major components. Some doors
have positive action slide latches for even greater ease of
access. All service fittings are conveniently located to mini-
mize time and effort.
Optional Factory Installed Economizers - Millennium units
offer economizers with Standard or Optional low leak damp-

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:
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.
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.
Built-in Hail Guard - Condenser coils angled at 30 degrees
from the vertical are inherently protected from damage due to
shipment, hail, etc.
Powder Paint - Industry leading 1000 salt spray hour paint
keeps the unit in great condition for years to come.
Induced Draft Furnace - This design provides a positive
exhaust of all combustion products.

460,000 / 12,000 = 38.33 Tons
RPM = 690
BHP = 10.7
Thus, a nominal 40 ton unit is selected.
NOTE: Either a Class I or Class II blower could be used.
2. Reference Cooling Capacity Table for a 40 ton unit with
standard evaporator coil.
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 10.7 BHP require-
ment.
a. Locate the table for a standard evaporator coil with
95° F air on the condenser.
b. Enter table at 13,000 CFM and 67°F WB air on
evaporator
SIZE OVERCURRENT PROTECTION DEVICE AND
DETERMINE CIRCUIT AMPACITY
c. Trace to 83° F Entering Dry Bulb column.
1. Find electrical tables for the basic 40 ton unit.
a. Enter table for 460-3-60 voltage.
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 Y34. Choose the
appropriate configuration for the next digit. Assuming
bottom return and supply, the fourth digit would be an
“A,” making the model Y34A.
b. Find 15 hp in the Supply Air Fan column.
c. Trace to Minimum Circuit Ampacity column - read
104.
d. Trace to Max. Fuse/Breaker Size column - read 110.
e. Size wire and overprotection device accordingly.
f. Check all footnotes.
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.

HOT WATER HEATING
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.
DO NOT use tin based solder. Brazing with tin
based solder could cause equipment damage or
possible injury to OCCUPANTS of the structure
that is being conditioned.
TABLE 11: HOT WATER COIL (1 ROW, 25 & 30
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.

The hot water piping must enter the unit through the floor of
the heat section compartment. The access doors to the com-
partment are gasketed so the compartment can be sealed.
However, as added protection for water leakage into the
space, the piping access holes should be sealed with a heat
resistant mastic (see the following illustration for approximate
location of the compartment and piping connections.

TABLE 22: STEAM COIL (1 ROW, 40 TON)
CAPACITY (MBH) AT STEAM PRESSURE (PSI)
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.
TABLE 23: STATIC RESISTANCE STEAM COIL
(1 ROW, 40 TON)
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.

PIPING CONNECTIONS
The steam piping must enter the unit through the floor of the
heat section compartment. The access doors to the compart-
ment are gasketed to the compartment can be sealed. How-
ever, as added protection for condensate leakage into the
space, the piping access holes should be sealed with a heat
resistant mastic. The following figure illustrates the approxi-
mate location of the compartment and piping connections.
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
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:
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
reference only. All blower speed changes must be
made by qualified personnel with strict adherence
to the fan laws.
Example:
Failure to properly adjust the total system air quan-
tity can result in extensive blower damage.
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
Use the equation to determine the required PD for the new
motor sheave (12,000 CFM / 11,000 CFM) x 6.7” = 7.31”.
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.
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
109%.
New drive speed = 1.091 x 856 = 933 RPM
New supply air = 1.091 x 11,000 = 12,000 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 =
(1.091)3 x 11.0 BHP = 1.2986 x 11.0 BHP = 14.3 BHP
New motor amps = (speed increase)3 x measured motor
amps at original start-up with 11,000 CFM and 856 RPM.

The 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.
These ratings include the condenser fan motors and the compressor motors but not the supply air blower motor.

order to use the indoor blower tables for high altitude applica-
tions, certain corrections are necessary.
CFM, STATIC PRESSURE, AND POWER - ALTI-
TUDE AND TEMPERATURE CORRECTIONS
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
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

The examples below will assist in determining the airflow per-
formance of the product at altitude.
blower tables to select the blower speed and the BHP
requirement.
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: 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.
Solution: At an elevation of 5,000 ft the indoor blower will still
deliver 6,000 CFM if the rpm is unchanged. However, Table
Since no temperature data is given, we will assume an air
be 0.832.
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.
Corrected static pressure = 1.5 x 0.832 = 1.248 IWC
Corrected BHP = 4.0 x 0.832 = 3.328
Suppose that the corresponding BHP listed in the table is 3.2.
This value must be corrected for elevation.
Example 2: A system, located at 5,000 feet of elevation, is to
BHP at 5,000 ft = 3.2 x .832 = 2.66
deliver 6,000 CFM at a static pressure of 1.5". Use the unit

Sound Power Ratings for Supply Air Blowers in our Millen-
nium Units with High Gas Heat, Economizer, 2: T/A Filters
and Wet DX Sound power calculations complements of Lau’s
revised “Whirlwind” application selection software for air mov-
ing components.
The sound ratings above occur at the blower wheel. To deter-
mine the sound rating at a unit’s supply and return air duct
connection, subtract the attenuation factors listed below.

OPTIONAL COMMUNICATION TRANSLATOR
Overview
When the control is using Enthalpy to control the Economizer,
it will also have an Outside Air Temperature enable Setpoint.
®
The ModLINC translator operates as a Modbus Client pro-
®
viding an interface between a BACnet control system and
®
devices that communicate using the Modbus RTU protocol.
The control will use two setpoints for Supply Air Temperature
for the Economizer operation. One will be for a small space
cooling demand and one for a large space cooling demand.
The ModLINC is preconfigured to provide an interface to
YORK UP products equipped with an Intelli-Comfort or Sim-
plicity-Elite controller and allows monitoring and control by a
®
third-party BACnet Building Automation System (BAS).
The control will have the ability to do Demand Ventilation
using one CO sensor.

must be connected to the BACnet network.
The control will have the ability to temper the ventilation air
during times when heating or cooling is not required.
The ModLINC translator is preconfigured to obtain opera-
tional data points from the controller and expose them on a
BACnet network.
