choice of location is possible, position unit on either north or
east side of building.
DUCTWORK
Ductwork should be designed and sized according to the
methods in Manual Q of the Air Conditioning Contractors of
America (ACCA).
A closed return duct system shall be used. This shall not
preclude use of economizers or outdoor fresh air intake. The
supply and return air duct connections at the unit should be
madewithflexiblejointstominimizethetransmissionofnoise.
The supply and return air duct systems should be designed for
the CFM and static requirements of the job. They should NOT
be sized to match the dimensions of the duct connections on
the unit.
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.
4. Roof structures must be able to support the weight of the unit
and its options and / or accessories. Unit must be installed on
a solid level roof curb or appropriate angle iron frame.
CAUTION: If a unit is to be installed on a roof curb or special
frame other than a YORK roof curb, gasketing
must be applied to all surfaces that come in contact
with the unit underside.
CAUTION: When fastening ductwork to the side duct flanges
on the unit, insert the screws through the duct
flanges only. DO NOT insert the screws through
the casing.
5. Maintain level tolerance to 1/2" maximum across the entire
length or width of the unit.
6. Elevate the unit sufficiently to prevent any blockage of the
air entrances by snow in areas where there will be snow ac-
cumulation. Check the local weather bureau for the ex-
pected snow accumulation in your area.
Outdoor ductwork must be insulated and water-
proofed.
Refer to Figure 5 for information concerning side and bottom
supply and return air duct openings.

THERMOSTAT
BLOWER SPEED SELECTION
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
thermostat for general installation procedure. Color coded
insulated wires (#18 AWG) should be used to connect
thermostat to unit. See Figure 4 for wiring details.
Three blower motor speeds are available on the direct-drive
units. The speed selection for the direct-drive units is
determined by the CFM and ESP requirements of the
applications. All units with belt-drive option have an adjustable
motor pulley to achieve the above conditions.
All direct-drive units with 208/230 voltage are shipped with the
wire labeled #116 connected to the “HIGH” speed tap on the
blowermotor. If a lowerblowermotor speedis desired, this wire
should be moved to the “MED” or “LOW” speed tap on the
motor for the speed desired.

Install the bracket on the left hand side of the unit as shown in
Figure 5. Several existing screws at the top of the unit and one
screw approximately midway down from the top will be used for
mounting the bracket. Screws should be loosened only - NOT
REMOVED. Matching holes in the bracket have elongated
keyways allowing easy installation. Re-tighten screws after
bracket is in place to ensure panels will remain leak tight.
Electric heaters are available as field-installed accessories.
Refer to Form 530.18-N7.1V for installation instruction. These
UL approved heaters are located within the central
compartment of the unit (see Figure 5 for access panel) with
the heating elements extending into the supply air chamber.
The heaters are wired for a single point power supply. Power
supply need only be brought into the single point terminal block

OPERATION
The heaters are wired for a single point power supply. Power
supply need only be brought into the single point terminal block
and thermostat wiring to the low voltage terminal strip located
in the upper portion of the unit control box.
reset by opening the 24V circuit either at the room thermostat
or at the unit disconnect.
HEATING SEQUENCE OF OPERATION
Fuses are supplied, where required, by the factory. Some KW
sizes require fuses and others do not. Refer to the accessory
instruction for electrical data.
The following sequence of operation is based on using a
standard single-stage or two-stage heating thermostat.
WITH POWER TO UNIT AND THERMOSTAT IN THE
HEATING MODE
COOLING SYSTEM
Single-Stage Heating:
The cooling section is a complete factory package utilizing an
air-cooled condenser. The system is factory-charged with
Refrigerant-22. The compressor is hermetically sealed and
internally sprung.
a. If the fan switch is in the “ON” position, the evaporator
blower motor relay (BR) will be energized through terminal
G to provide continuous blower operation. If the fan switch
is in the “AUTO” position, the blower will operate only when
there is a call for heating by the thermostat.
The compressors have inherent (internal) protection. If there is
an abnormal temperature rise in the compressor, the protector
will open to shut down the compressor.
b. Upon a call for heat by the thermostat, the first stage of heat
will be energized. Sequencer 1S (or contactor 2M) is al-
ways the first and last to complete its timing cycle and con-
trols power to the evaporator blower motor.
PRELIMINARY OPERATION COOLING
After the installation has been completed, the crankcase
heater of the compressor must be energized for at least 4 hours
before starting the unit. After this initial warm-up, the
compressor should be given three false starts (energized just
long enough to make a few revolutions) with a 5 minute delay
between each start before being put into full time service.
c. The thermostat will cycle the electric heat to satisfy the
heating requirements of the conditioned space.
Two-Stage Heating:
a. If the fan switch is in the “ON” position, the evaporator
blower motor relay (BR) will be energized through terminal
G to provide continuous blower operation. If the fan switch
is in the “AUTO” position, the blower will operate only when
there is a call for heating by the thermostat.
NOTE: Prior to each cooling season, the crankcase heater
must be energized at least 10 hours before the system
is put into operation.
b. Upon a call for first-stage heat by the thermostat, the first
stage of heat will be energized.
COOLING SEQUENCE OF OPERATION
Single-Stage Cooling:
If the thermostat calls for the second stage of heat, the
second stage of heat will be energized.
As before, sequencer 1S (or contactor 2M) maintains
control of the evaporator blower.
When the thermostat calls for “cooling”, “R” is closed to “G” and
“Y1" (wiring schematic) which completes the low voltage
control circuit, immediately energizing the compressors,
condenser fan motor and blower motor simultaneously.
c. The thermostat will cycle the electric heat to satisfy the
heating requirements of the conditioned space.
CONTINUOUS BLOWER - Continuous blower operation is
possible by closing the R to G circuit on the thermostat.
Two-Stage Cooling:
A two-stage cooling thermostat may be used if the unit has an
economizer. First-stage cooling is provided by the economizer
if the outdoor air enthalpy is acceptable, and second-stage
cooling is provided by the compressor. Jumper wire J1 must be
removed. Refer to unit wiring diagram.

HEAT ANTICIPATOR SETPOINTS
It is important that the anticipator setpoint be correct. Too high
of a setting will result in longer heat cycles and a greater
temperature swing in the conditioned space. Reducing the
value below the correct setpoint will give shorter “ON” cycles
and may result in the lowering of the temperature within the
conditioned space. Refer to Table 10 for the required heat
anticipator setting.
obtain the desired supply air CFM. Refer to Table 7 for blower
motor and drive data. The tension on the belts should be
adjusted as shown in Figure 7.
Start the supply air blower motor. Adjust the resistances in both
the supply and the return air duct systems to balance the air
distribution throughout the conditioned space. The job
specifications may require that this balancing be done by
someone other than the equipment installer.
CHECKING SUPPLY AIR CFM
The speed of the supply air blower will depend on the required
CFM, the unit accessories and the static resistances of both the
supply and the return air duct systems. With this information,
To check the supply air CFM after the initial balancing has been
completed:
1. Remove the (two) " dot plugs from the holes located on
the filter access panel side of the unit.

coil may vary greatly, measuring the pressure drop across
a wet coil under field conditions would be inaccurate. To
assure a dry coil, the compressors should be de-energized
while the test is being run.
the speed for the supply air blower can be determined from the
static resistance and blower performance data on Tables 3 thru

MAINTENANCE
NORMAL MAINTENANCE
CAUTION: Prior to any of the following maintenance proce-
dures, shut off all power to the unit to prevent
personal injury.
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 coil clean. Use a
brush, vacuum cleaner attachment, or other suitable means. If
water is used to clean coil, be sure power to the unit is shut off
prior to cleaning.
FILTERS - Inspect once a month. Replace disposable or clean
permanent type as necessary. DO NOT replace permanent
type with disposable.
NOTE: Exercise care when cleaning the coil so that the coil
fins are not damaged.
MOTORS - Indoor fan and outdoor fan motors are permanently
lubricated and require no maintenance.
Do not permit the outdoor air discharge to be obstructed by
overhanging structures of shrubs.
