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'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, 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
stainless steel, for long life. And, it is sloped at the 1/4” per
foot recommended by the new ASHRAE ventilation draft
standard, with an extra large drain connection capable of
removing up to three gallons of condensate per minute. Best
of all, the drain pan is easily removed from the unit so that it
can be cleaned at regular intervals.
Unitary Products Group
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 10 ton circuits (12.5
ton circuits on the 25 ton) - 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.

036-21091-004-B-0205
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.
Heating Done Your Way - Millennium offers the choice of natural gas or propane, electric resistance heat, hot water heat,
steam, or no heat at all. Very simply, the choice is yours.
INSTALLATION FEATURES
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 1” isolator springs are
typically sufficient for most applications, but when sound and
vibration transmission are a major concern, YORK offers 2”
isolation springs for even greater protection from supply air
fan noise and vibration.
Optional TechniCoated Coated Condenser 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.
High Capacity Evaporator Coils - For those applications
which require slightly more capacity than offered by the standard Millennium product, YORK offers the option of higher
capacity evaporator coils, boosting cooling output without
increasing unit size.
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.
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.
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.
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.
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 an optional factory installed economizer with low leak
dampers. Comparative enthalpy, single enthalpy and dry bulb
control 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 factory wired transformer to power the outlet from the single
point power connection; the convenience outlet remains
operational when the disconnect is open.

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.
L E A K D A M P E R S
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.

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.

STEAM HEATING
TABLE 18: STEAM COIL (1 ROW, 40 TON)1
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.

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 22, 23 and 24 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.
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.
A 30-ton unit was selected to deliver 12,000 CFM with a 20
HP motor and a 966 RPM drive, but the unit is only delivering
11,000 CFM per Figures 22, 23, and 24.
Use the equation to determine the required PD for the new
motor sheave (12,000 CFM / 11,000 CFM) x 6.9” = 7.53”
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
108.7%.
New drive speed = 1.087 x 966 = 1,050 RPM
New supply air
= 1.087 x 11,000 = 11,957 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 966 RPM =
(1.087)3 x 13.5 BHP = 1.284 x 13.5 BHP = 17.3 BHP
New motor amps = (speed increase)3 x measured motor
amps at original start-up with 11,000 CFM and 966 RPM.

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 32 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
32 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 32 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
48
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
