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 customers what they wanted in a new rooftop line, we were careful 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 ratings 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 provides 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 frequently 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 condensate per minute. It is available in either powder coat
painted steel or stainless steel for long life.
Johnson Controls Unitary Products
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 expansion 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 customers 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, giving 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.

246837-YTG-P-1214
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.
prevents the need for a separate 120 volt circuitry on the roof
to meet local codes and provides easily accessible power for
tools, lighting and other 120 volt items. The optional factory
convenience outlet is only available in conjunction with a factory installed disconnect.
Heating Done Your Way - Millennium offers the choice of natural gas standard or modulating gas heat, electric resistance
heat, hot water heat, steam, or no heat at all. Very simply, the
choice is yours.
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.
INSTALLATION FEATURES
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 supply air fan noise and vibration.
With YORK Millennium, high performance doesn't mean high
complexity. YORK listened carefully to make sure that Millennium 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.
Corrosion Resistant Coils- Many industrial and seacoast
applications require enhanced protection from corrosive environments.
Full Range of Air Flows and Static Pressures - The Millennium design gives a complete offering of supply air flows and
static pressure combinations to meet most every application
requirement.
Optional TechniCoated Coated Condenser and Evaporator Coils - Many industrial and seacoast applications
require enhanced protection from corrosive environments. The special dipped phenolic coating process
provides a high level of protection for the exposed condenser coil.
Single Power Point Connection - Millennium units have a single gas and electric connection, minimizing time at the job
site. For further installation flexibility, power and gas connections may be brought up from the curb or through the side of
the unit.
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.
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 positive action slide latches for even greater ease of access. All
service fittings are conveniently located to minimize time and
effort.
Optional Factory Installed Economizers - Millennium units
offer economizers with Standard or Optional low leak dampers. Comparative enthalpy, single enthalpy and dry bulb control are available.
Optional Factory Installed Disconnect- A factory installed
power disconnect is offered to easily allow shut off of power
to the unit. The factory installed disconnect eliminates the
need for a bulky, unattractive field installed disconnect to be
mounted on the side of the unit. The factory disconnect is
mounted internally to the unit, just behind the electrical box
access panel and can also be ordered with a powered 120
volt convenience outlet that remains powered after the unit
power has been disconnected.
Optional Factory Installed Powered Convenience Outlet- A
factory installed powered 120 volt convenience outlet option

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 registered 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.
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 contacting 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.
Low Profile - Millennium units stand only 64” above their
curb, minimizing potential aesthetic conflicts.

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.
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

For all hot water coils the entering water temperature should
not exceed 200°F.

Based on 60°F entering air temperature, 2.00” maximum pressure drop across the hot water coil.
PIPING CONNECTIONS
The hot water piping must enter the unit through the floor of
the heat section compartment. The access doors to the compartment 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.
NOTE: Water pressure drop numbers are based on 60°F
entering air temperature, 2.00” maximum air pressure drop across the hot water coil(s). AHRI certified
ratings at other conditions are available upon
request. Hot water coils are approved for use with
glycol (rates available upon request).
1. Hot water, steam or electric heat is not available for
front or rear supply.

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 supply 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 prevent 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 conditioned 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.

The steam piping must enter the unit through the floor of the
heat section compartment. The access doors to the compartment are gasketed to the compartment can be sealed. However, 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 approximate location of the compartment and piping connections.
*Hot water, steam coil or electric heat not available for front or

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:
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 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 quantity 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
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”.
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
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.

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

CFM, STATIC PRESSURE, AND POWER - ALTITUDE AND TEMPERATURE CORRECTIONS
order to use the indoor blower tables for high altitude applications, certain corrections are necessary.
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.
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 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 performance 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 information is given so 70°F is assumed.
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.
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.
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
34
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

EQUIPMENT CONTROL FEATURES
Units will come with the new state of the art Simplicity SE
(Smart Equipment) control system. The new unit control
incorporates the best of the already proven Simplicity® unitary controls and creates a more robust, intelligent control.
The goal of this control is to utilize cutting edge technology
making the equipment easier to install, operate, and service.
All units are Factory commissioned, configured, and run
tested.
Versatile - The Simplicity SE control can be configured to
use with a standard thermostat (easy to connect screw terminals), A zone sensor, or can be setup to communicate with
multiple BAS communication protocols to integrate with building automation systems.
Reduce field installed complexity - Each unit will comes
equipped with factory installed supply air, return air, and outdoor air temperature sensors providing key temperature
readings thus reduce field installed complexity.
On-board USB Port - The new control comes with a long list
of features including data logging, current and previous system faults and software update capabilities using the on
board USB port and common flash drive. Energy use monitoring capabilities allow custom tailoring to allow a system to
80
Safety Monitoring - The control monitors the outdoor, supply, and return air temperatures and the high and low pressure switch status on the independent refrigerant circuits. On
units with heating the gas valve and high temperature limit
switches are monitored on gas and electric heating units. The
control also monitors the voltage supplied to the unit and will
protect the unit if low voltage due to a brown out, or other
electrical issue occurs.
Low Ambient - An integrated low-ambient control allows
units to operate in the cooling mode down to 0°F outdoor
ambient without additional components or intervention.
Optionally, the control board can be programmed to lockout
the compressors when the outdoor air temperature is low or
when free cooling is available.
Anti-Short Cycle Protection - To aid compressor life, an
anti-short cycle delay is incorporated into the standard control. Compressor reliability is further ensured by programmable minimum run times. For testing, the anti-short cycle delay
can be temporarily overridden with the push of a button.
Fan Delays - Fan on and fan off delays are fully programmable. Furthermore, the heating and cooling fan delay times are
independent of one another. All units are programmed with
default values based upon their configuration of cooling and/
or heating capacity.
Nuisance Trip Protection and Three Strikes - To prevent
nuisance calls, the control board uses a three times, you're
out philosophy. The high, low-pressure switch, anti-freeze
protection, low voltage or heating high limit must trip three
times within two hours before the unit control board will lock
out the associated compressor. The same safety must trip
three times before a hard lockout will occur.
The control will operate and monitor up to 3 stages of heat
independently.
The control shall monitor the Gas Heat operation in the heating mode. It shall monitor the gas valve when there is a call
for heating. The control shall alarm when there is a call for
heat and no gas valve voltage after 5 minutes.
