Location
Rigging And Handling
Use the following guidelines to select a suitable location for
these units.
Exercise care when moving the unit. Do not remove any
packaging until the unit is near the place of installation. Rig the
unit by attaching chain or cable slings to the lifting holes
provided in the base rails. Spreader bars, whose length
exceeds the largest dimension across the unit, MUST be used
across the top of the unit.
1. Unit is designed for outdoor installation only.
2. Condenser must have an unlimited supply of air. Where a
choice of location is possible, position unit on either north
or east side of building.
3. For ground level installation, a level pad or slab should be
used. The thickness and size of the pad or slab used
should meet local codes and unit weight. Do not tie the
slab to the building foundation.
If a unit is to be installed on a roof curb other than a
York roof curb, gasketing must be applied to all
surfaces that come in contact with the unit underside.
®
4. For roof top installation, be sure the structure can support
the weight of the unit plus any field installed components.
Unit must be installed on a level roof curb or appropriate
angle iron frame providing adequate support under the
compressor/condenser section.
5. Maintain level tolerance of unit to 1/8” maximum.
Before lifting, make sure the unit weight is distributed
equally on the rigging cables so it will lift evenly.
Units may be moved or lifted with a forklift. Slotted openings in
the base rails are provided for this purpose.
Do not permit overhanging structures or shrubs to
obstruct condenser air discharge outlet, combustion air
inlet or vent outlets.
Clearances
All panels must be secured in place when the unit is
lifted.
All units require certain clearances for proper operation and
service. Refer to Table 4 for the clearances required for
construction, servicing and proper unit operation.
The condenser coils should be protected from rigging
cable damage with plywood or other suitable material.

Figure 6: Roof Curb
Ductwork
NOTE: Be sure to note supply and return openings.
Refer to Figures 4 and 5 for information concerning rear and
bottom supply and return air duct openings.
These units are adaptable to downflow use as well as rear
supply and return air duct openings. To convert to downflow,
use the following steps:
Roof Curb
1. Remove the duct covers found in the bottom return and
supply air duct openings. There are four (4) screws securing
each duct cover (save these screws to use in Step 2).
On applications when a roof curb is used, the unit must be
positioned on the curb so the front of the unit is tight against the
curb.
2. Install the duct covers (removed in step one) to the rear
supply and return air duct openings. Secure with the four
(4) screws used in step one.
Filters
Single phase units are shipped without a filter or filter racks. It is
the responsibility of the installer to secure a filter in the return air
ductwork or install a Filter/Frame Kit (1FF0114).
3. Seal duct covers with silicone caulk.
Duct work should be designed and sized according to the
methods of the Air Conditioning Contractors of America
(ACCA), as set forth in their Manual D.
A filter rack and high velocity filters are standard on three phase
units.
Filters must always be used and must be kept clean. When
filters become dirt laden, insufficient air will be delivered by the
blower, decreasing your units efficiency and increasing
operating costs and wear-and-tear on the unit and controls.
A closed return duct system shall be used. This shall not
preclude use of economizers or ventilation air intake. Flexible
joints may be used in the supply and return duct work to
minimize the transmission of noise.
Filters should be checked monthly; this is especially important
since this unit is used for both heating and cooling.
Condensate Drain
A condensate trap is recommended to be installed in the
condensate drain. The plumbing must conform to local codes.
When fastening duct work to the side duct flanges on
the unit, insert the screws through the duct flanges only.
DO NOT insert the screws through the casing. Outdoor
duct work must be insulated and waterproofed.
Use a sealing compound on male pipe threads. Install the
condensate drain line (3/4” NPTF) to spill into an open drain.
1. 8” Roof Curb also available.

Service Access
Thermostat
Access to all serviceable components is provided at the
following locations:
The room thermostat should be located on an inside wall
approximately 56" above the floor where it will not be subject to
drafts, sun exposure or heat from electrical fixtures or
appliances. Follow manufacturer's instructions enclosed with
the thermostat for general installation procedure. Six color
coded insulated wires (minimum #18 AWG) should be used to
connect thermostat to unit. See Figures 7 and 8.
• Blower compartment access panel
• Electrical/Filter access panel
• Compressor access panel
• Refrigerant connections
Refer to Figures 1 and 3 for location of these access locations
and minimum clearances in Table 4.
Power And Control Wiring
Field wiring to the unit must conform to provisions of the current
N.E.C. ANSI/NFPA No. 70 or C.E.C. and/or local ordinances.
The unit must be electrically grounded in accordance with local
codes or, in their absence, with the N.E.C./C.E.C. Voltage
tolerances which must be maintained at the compressor
terminals during starting and running conditions are indicated
on the unit Rating Plate and Table 5.
This system uses R-410A Refrigerant which operates at
higher pressures than R-22. No other refrigerant may be
used in this system. Gage sets, hoses, refrigerant
containers and recovery systems must be designed to
handle R-410A. If you are unsure, consult the
equipment manufacturer. Failure to use R-410A
compatible servicing equipment may result in property
damage or injury.
The wiring entering the cabinet must be provided with
mechanical strain relief.
A fused disconnect switch should be field provided for the unit.
If any of the wire supplied with the unit must be replaced,
replacement wire must be of the type shown on the wiring
diagram.
Electrical line must be sized properly to carry the load. Each
unit must be wired with a separate branch circuit fed directly
from the meter panel and properly fused.
Wear safety glasses and gloves when handling
refrigerants. Failure to follow this warning can cause
serious personal injury.
Refer to Figures 7, 8 and 9 for typical field wiring and to the
appropriate unit wiring diagram for control circuit and power
wiring information.
Refer to Figure 11 for the R-410A quick reference guide.

Compressors
The scroll compressor used in this product is specifically designed
to operate with R-410A Refrigerant and cannot be interchanged.
Do not leave the system open to the atmosphere. Unit
damage could occur due to moisture being absorbed by
the POE oil in the system. This type of oil is highly
susceptible to moisture absorption
This system uses R-410A Refrigerant which operates at
higher pressures than R-22. No other refrigerant may be
used in this system.
POE (polyolester) compressor lubricants are known to cause
long term damage to some synthetic roofing materials.
The compressor also uses a polyolester (POE oil), Mobil 3MA
POE. This oil is extremely hydroscopic, meaning it absorbs water
readily. POE oil can absorb 15 times as much water as other oils
designed for HCFC and CFC refrigerants. Take all necessary
precautions to avoid exposure of the oil to the atmosphere.
Exposure, even if immediately cleaned up, may cause
embrittlement (leading to cracking) to occur in one year
or more. When performing any service that may risk
exposure of compressor oil to the roof, take precautions
to protect roofing.
Unitary Products Group

288429-YIM-A-0307
Procedures which risk oil leakage include, but are not limited to,
compressor replacement, repairing refrigerant leaks, replacing
refrigerant components such as filter drier, pressure switch,
metering device or coil.
Phasing
Three-phase, scroll compressors operate in only one direction.
If the scroll is drawing low amperage, has similar suction and
discharge pressures, or is producing a high noise level, the
scroll is misphased. Change the incoming line connection
phasing to obtain the proper rotation.
Units are shipped with compressor mountings which are factory
adjusted and ready for operation.
Scroll compressors require proper rotation to operate
properly. Failure to check and correct rotation may result
in property damage.
Do not loosen compressor mounting bolts.

Airflow may be increased by 10% by moving the “ADJ” jumper
to “B”. Airflow may be decreased by 10% by moving the “ADJ”
jumper to “C”.
Blower Speed Selection
The variable speed blowers are designed to deliver constant
CFM regardless of the external static pressure (ESP) in the
NOTE: CFM indicator light flashes once for every 100 CFM
ductwork. Therefore, if too many supply registers are closed, a
filter becomes clogged, or there is a restriction in the ductwork,
the motor will automatically operate at a higher speed to
compensate for the higher ESP. This may result in a higher
operating sound level.
(i.e., 12 flashes = 1200 CFM).
To Set Delay Profile:
Every unit has multiple cooling “blower off delay” profiles to
optimize system performance and efficiency. Refer to Table
19 for the regional climate in your area. Place the “DELAY”
jumper tap on the CFM selection board to the appropriate pin
setting.
These units have variable speed motors that automatically
adjust to provide constant CFM from 0.2" to 0.6" w.c. static
pressure. From 0.6" to 1.0" static pressure, CFM is reduced by
2% per 0.1" increase in static. Operation on duct systems with
greater than 1.0" w.c. external static pressure is not
recommended.
To Set Electric Heat CFM:
The airflow required for Electric Heat may be different than for
cooling.
To Set Cooling CFM:
Refer to Table 10 for the minimum required CFM for the
electric heater installed. Find the desired airflow in Tables 7
and 8. Set the “Heat” Jumper on the CFM selection board to
tap shown.
Refer to Tables 7 and 8 for the possible cooling and heating
CFM selections.
Find the recommended system airflow for the unit model.
Set desired cooling airflow by moving the jumper on the “Cool”
tap located on the CFM selection board as indicated in Tables
7, 8 and Figure 10.

Fan Only CFM:
operate the blower at high speed and energizes the
compressor solenoid to close the bypass ports so that the
compressor operates at full capacity. If the outdoor fan
motor has an ECM controller, the 24 volts at "Y2" signals
the motor to operate at high speed.
When the connection is made from “R” to “G”, the fan only
mode is activated. In this mode, the blower will deliver 75% of
the cooling system CFM. This connection is factory set from the
manufacturer and cannot be field adjusted.
4. When the cooling demand is satisfied, the 24 volt "Y1" and
"Y2" signals are removed and the M1 contactor is de-
energized. If the fan switch on the thermostat is in the "ON"
position, the blower will continue to run at 75% of the rated
airflow. If the fan switch is in the "AUTO" position, the
blower will continue to run for a short period as determined
by the "DELAY" jumper setting on the CFM Selector board.

Heating Sequence Of Operations
<ꢂ<ꢀ
1. If the fan switch on the thermostat is in the "ON" position, the
24 volts at "G" signals the ECM motor controller to operate
the blower at 75% of the rated airflow. If the fan switch on the
thermostat is in the "AUTO" position, the blower operates
only when there is a call for heating by the thermostat.
<ꢁ
2. For units equipped with supplementary electric heat, 24
volts at "W" sends 24 volts to "W2" on the fan control board.
The 24 volt signal energizes all stages of electric heat.
3. When the heating demand is satisfied, the 24 volt "W" signal
is removed and the electric heat is de-energized. The M1
contactor is de-energized when the 24 volt "Y" signal is
removed. If the fan switch on the thermostat is in the "ON"
position, the blower will continue to run at 75% of the rated
airflow. If the fan switch is in the "AUTO" position, the blower
will continue to run for a short period as determined by the
"DELAY" jumper setting on the CFM Selector board.

Operation
Electric Heat Limit Switch Operation
Cooling Sequence Of Operations
The limit switch responds to over-temperature conditions in the
air duct. Opening the device results in dropping power to the
relays. The control logic will also respond by turning off the
relays. After four limit cycle trips the unit goes into a 1 hour soft
lockout period. If the control "sees" another limit cycle during
this period, the unit will go into a hard lockout condition. Once in
a hard lockout state, the fan is locked on and the heaters are
disabled. Only a power cycle will clear this state.
1. If the fan switch on the thermostat is in the "ON" position, the
24 volts at "G" signals the ECM motor controller to operate
the blower at 75% of the rated airflow. If the fan switch on the
thermostat is in the "AUTO" position, the blower operates
only when there is a call for cooling by the thermostat.
2. If the 2-stage thermostat calls for the first stage of cooling,
the 24 volts at "Y1" signals the ECM controller to operate the
blower at low speed and closes the contactor coil M1. Power
is supplied to the compressor and outdoor fan motor. When
the fan switch on the thermostat is in the "AUTO" position,
the indoor blower motor is energized at the low-speed
cooling airflow.
During the soft lockout period, the fan responds to thermostat
input but the heaters are enabled. This is to sense a failed
heater relay. The limit cycle count is reset at the start of a heat
request. If the limit remains open for period of 80 seconds or
more, the control is immediately put into a hard lockout
condition. Only a power cycle will clear this state.
3. If the 2-stage thermostat calls for the second stage of
cooling, the 24 volts at "Y2" signals the ECM controller to

Maintenance
Normal Maintenance
Exercise care when cleaning the coil so that the coil fins
are not damaged.
Do not permit the hot condenser air discharge to be
obstructed by overhanging structures or shrubs.
Prior to any of the following maintenance procedures,
shut off all power to the unit, to avoid personal injury.
Troubleshooting
Periodic maintenance consists of changing or cleaning filters
and general cleaning of the outdoor coil.
FILTERS - Inspect once a month. Replace Disposable or clean
Permanent Type as necessary. DO NOT replace Permanent
Type with Disposable.
Troubleshooting of components necessarily requires
opening the electrical control box with the power
connected to the unit. Use extreme care when working
with live circuit! Check the unit nameplate for the correct
range before making any connections with line
terminals.
MOTORS - Indoor and outdoor fan motors are permanently
lubricated and require no maintenance.
OUTDOOR COIL - Dirt should not be allowed to accumulate on
the outdoor coil surface or other parts in the air circuit. Cleaning
should be as often as necessary to keep the coil clean. Use a
brush, vacuum cleaner attachment, or other suitable means. If
water is used to clean the coil, be sure that the power to the unit
is shut off prior to cleaning.
The wire number or color and terminal designations
referred to may vary. Check the wiring label inside the
control box access panel for the correct wiring.
