3. LOCATING THE UNIT
ACCESS PANELS
See Figure 1 for a general view of unit and location of
access panels.
CLEARANCES
The location MUST allow for minimum clearances and
should not be adjacent to a patio or other area where the
unit's operating sound level might be objectionable.
NOTE: Units with available filter racks (3-1/2 to 4 ton), need
a26" minimum clearance at side of unit for removal of filters.
See chart below if unit is going to be placed near
combustible construction or materials.
While minimum clearances are acceptable for safety
reasons, they may not allow adequate air circulation around
the unit for proper operation inthe cooling mode. Whenever
possible, it is desirable to allow additional clearance,
especially around the condenser inlet and discharge
openings.
Do NOT install the unit in a location that will permit
discharged air from the condenser to recirculate to the
condenser inlet.

NOTICE
Unit will NOT operate properly unless it is installed lev-
el front to rear and side to side. The slope MUST NOT be
greater than 1/8" per foot (10mm per meter). For side to
side leveling, the drain side MUST always be lower.
Ground Level Installation
Ground level platform requirements:
- The unit MUST be situated to provide safe access for
servicing.
- The unit must be level and supported above grade by
beams, platform, or a pad. Platform or pad can be of
open or solid construction but should be of permanent
materials such as concrete, bricks, blocks, steel, or
pressure-treated timbers approved for ground contact.
Soil conditions must be considered so that the platform
or pad does not shift or settle and leave the unit partially
supported.
- Position platform separate from building foundation.
- Install inwell-drained area, with top surface of platform
above grade level.
- Platform must be high enough to allow for proper
condensate trap installation and drainage. See
FIGURE 2 and associated text for more information
about condensate drainage.
Rooftop Installation
Rooftop platform requirements:
- The unit MUST be situated to provide safe access for
servicing.
- The existing roof structure MUST be adequate to
support the weight of the unit or the roof MUST be
reinforced.
Check the weight of the unit in relation to the roof
structure and local building codes or ordinances and
reinforce roof structure if necessary. See page 11 of this
manual for unit weights.
- Support for the unit MUST be level and strong enough
to carry unit weight. The support may consist of a
platform or a combination of platform and roof beams or
curb.
- See Hoisting section for hoisting instructions.
HOISTING
NOTE: All access panels MUST be secured in place before
hoisting.
The unit should be hoisted with two lifting slings. Attach the
slings to rigging shackles that have been hooked through
holes in the base rail.
Two spreader bars MUST be placed on top of the unit to
protect the unit from damage from the pressure exerted by
the slings. Make sure that all equipment is adequate to
handle the weight ofthe unit and that the slings will not allow
the unit to shift.
Refer to FIGURE 9 on page 11 ofthis manual for illustrated
rigging instructions and weight chart.
DOWNFLOW CONVERSION
NOTE: In downflow applications with roof curbs or jack
stands, the center rail under the unit must be removed. The
center rail is attached to the base rail with screws.
These units are adaptable to downflow use. To convert to
downflow use, follow these steps:
1. Remove the blockoff plates found in the return air
compartment and the supply air compartment.
NOTE: Blockoff plate in the supply air compartment only
contains one screw. If reinstalling plate, back part of plate
MUST fit into mating dimples on flange. To reinstall, slant
plate into dimples, then put plate into position and fasten
with screw.
2. Install the removed plates on the horizontal return and
supply air openings.
3. Install roof curb on the building. Be sure to follow all
directions included with curb and all applicable building
codes in your installation.
Condensate Drain
The condensate drain outlet is a 3/4" (19.1 mm) female PVC
connection located at the bottom on the left hand side (see
FIGURE 2).
The circulating blower creates a negative pressure on the
condensate drain linethat can prevent the condensate from
draining properly. To combat this negative pressure, a field
supplied condensate trap that will allow a standing column
of water of at least 2" (50.8mm) MUST be installed. Top of
outlet from trap MUST be at least 1" (25.4mm) below top of
outlet from unit. Install the trap as near to the unit as
possible for proper drainage.
A 3/4" (19.1 mm) drain line MUST be installed if required by
local codes or iflocation of unit requires it. Run the drain line
to an open drain or other suitable disposal point.

REDUCED EQUIPMENT LIFE HAZARD
Failure to follow these precautions could result in
damage to the unit being installed.
1) Make all electrical connections in accordance with
National Electric code (NEC) NFPa 70 and local electrical
codes governing such wiring. In Canada, all electrical
connections must be in accordance with CSA standard
C22.1, Canadian Electrical Code Part 1, and applicable
local codes. Refer to unit wiring diagram.
2) Use only copper conductor for connections
between field-supplied electrical disconnect switch and
unit. DO NOT USE ALUMINUM WIRE.
3) Be sure that high-voltage power to unit is within
operating voltage range indicated on unit rating plate.
4) Do not damage internal components when drilling
through any panel to mount electrical hardware,
conduit, etc. Consult local power company for
correction of improper voltage and/or phase imbalance.
Disconnect Switch
The unit must have separate electrical service with a
field-supplied, waterproof, disconnect switch mounted at,
or within sight from, the unit. Refer tothe unit rating plate for
maximum fuse/circuit breaker size and minimum circuit
amps (ampacity) for wire sizing.
Ground Connections
Do NOT complete line voltage connections until unit is
permanently grounded. All linevoltage connections and the
ground connection MUST be made with copper wire.
A ground lug is installed in the control box area for the
ground connection. Use a copper conductor of the
appropriate size from the unit to a grounded connection in
the electrical service panel or a properly driven and
electrically grounded ground rod. See warning above.
Line Voltage Wiring - (Wiring Diagrams page 12 & 13)
Connections for linevoltage are made in the unit control box
area. Refer to wiring diagram located on the Access panel.
For access, remove the burner access panel.
1. Run the high voltage (L1, L2) and ground leads into the
control box.
2. Connect ground lead to chassis ground connection.
3. Connect L1 to pressure lug connection 11 of the
compressor contactor.
4. Connect L2 to pressure lug connection 23 of the
compressor contactor.
Thermostat / Low Voltage Wiring
Location of the thermostat has an important effect on home
comfort. FOLLOW THE THERMOSTAT INSTRUCTION
MANUAL FOR CORRECT LOCATION, MOUNTING, AND
WIRING.
For 2 to 3-1/2 Ton Models Only:
A single stage thermostat is required for proper operation.
Thermostat must have the terminals shown in Figure 3 or
there equivalent. Some electronic thermostats use low
voltage from the unit for power for temperature display and
programming. These electronic thermostats will have a "C"
terminal. The outdoor unit has color-coded wires for easy
connection. Using wire nuts, follow Figure 3 for proper
connections:
FIGURE 3 2 to 3-1/2 Ton Thermostat Connections
Thermostat and subbase Unit Control Power
For 4 Ton Models Only:
A two-stage thermostat is required for proper operation.
Thermostat should have the terminals shown in Figure 4 or
there equivalent. Some electronic thermostats use low
voltage from the unit for power for temperature display and
programming. These electronic thermostats will have a "C"

connections:
FIGURE 4 4 Ton Thermostat Connections
Thermostat and subbase Unit Control Power
THERMOSTAT HEAT ANTICIPATOR
Some thermostats have an adjustable heat anticipator. The
heat anticipator prevents temperature overshoot in heating
mode. If the heat doesn't turn off until the set point
temperature on the thermostat is exceeded, then the
anticipator setting istoo low. If the heat turns off before the
thermostat reaches the set point temperature on the
thermostat, then the anticipator setting is too high. Follow
the thermostat instruction manual for proper adjustment of
the heat anticipator.
Final Electrical Check Ductwork Connections
1. Make a final wiring check to be sure system is correctly
wired. Inspect field installed wiring and the routing to
ensure that rubbing or chafing due to vibration will not
occur.
NOTE: Wiring MUST be installed so it is protected from
possible mechanical damage.
5. DUCTWORK
Ductwork Sizing
The maximum recommended velocity in trunk ducts is 1000
feet per minute. The maximum recommended velocity in
branch ducts is 800 feet per minute.
Ductwork sizing affects the discharge temperature, airflow
velocity, and efficiency of the system. Be sure to properly
size ductwork to the capacity of the unit and to the airflow
requirements of the conditioned space. Failure to properly
size ductwork can result in inadequate airflow and poor
The use of flexible, non-combustible connectors between
main trunk ducts and supply and return air plenums is
permitted. If flexible connectors are used, they should be
protected from potential mechanical damage such as
punctures and tears.
NOTE: When connecting the supply and return plenums to
the unit, make sure that the plenums are sealed against the
side casing of the unit and do not interfere with removal of
the top of the unit.
FILTERS
All return air MUST pass through a filter before entering the
unit. An electronic air cleaner, optional filter racks, or other
accessible filter arrangement must be installed in the return
air ductwork. Minimum recommended filter sizes are listed
in FIGURE 5 and are based on maximum face velocities of
300 ft/min for disposable filters and 500 ft/min for washable
(high velocity) filters. See figure 5 for filter sizes.

running the correct heating and cooling speeds.
2. Check to see that clean, properly sized air filters are
installed.
3. Replace all service access panels.
Check the unit's operation as outlined in the following
instructions. If any unusual sparking, odors or unusual
noises are encountered, shut off electric power
immediately. Recheck for wiring errors, or obstructions in or
near blower motors.
1. Set thermostat Heat-Cool selector to OFE
2. Set thermostat fan switch to AUTO.
3. Turn electric power ON. Nothing should start running.
4. Set thermostat fan switch to ON.
5. Reset thermostat fan switch to AUTO.
8. SEQUENCE OF OPERATION
ELECTRICAL SHOCK HAZARD.
Failure to follow this warning could result in personal
injury, death and/or property damage.
Turn off electric power supply at disconnect switch or
service panel before removing any access or service
panel from unit.
Cooling Operation (PHF324 -42)
With a call for cooling (Y), the indoor fan energizes
immediately where as the contactor energizes after a 5
minute time delay (incase of an initial start up) starting the
compressor and the outdoor fan motor. When the cooling
demand ismet, (Y) de-energizes, shutting the compressor,
indoor fan and the outdoor fan.
Cooling Operation (PHF348)
These units utilize a 2 stage indoorthermostat. With a first
stage call for cooling (Y1), the indoor fan (low stage)
energizes immediately where as the contactor energizes
after a 5 minute time delay (incase of an initial start up)
starting the compressor (low stage) and the outdoor fan
motor. Ifthe low stage operation cannot satisfy the cooling
demand, the second stage cooling (Y2) energizes
switching the compressor into high stage cooling through
energizing an internal solenoid valve inside the scroll
compressor and switching the indoor fan into high stage.
When second stage cooling is satisfied, Y2 de-energizes
switching the compressor and the indoor fan into low stage
cooling. When the low stage cooling demand is met, Y1
de-energizes shutting the compressor, indoor fan and the
outdoor fan.
Heating Operation (PHF324 -42)
With a call for heating (Y), the indoor fan (low stage)
energizes immediately where as the contactor energizes
after a 5 minute time delay (incase of an initial start up)
starting the compressor and the outdoor fan motor. If (Y)
cannot satisfy the heating demand, the auxiliary or back up
heat (W2) energizes. Incase of staged heating, W3 is
energized if the demand is not met. The highest airflow
selected is run while the electric heat is in operation. When
heating demand is met, W3, W2 and Y sequentially
de-energize shutting the compressor, indoor fan and the
outdoor fan.
Heating Operation (PHF348)
With a first stage call for heating (Y1), the indoor fan (low
stage) energizes immediately whereas the contactor
energizes after a 5 minute time delay (incase of an initial
start up) starting the compressor (low stage) and the
outdoor fan motor. Ifthe low stage operation cannot satisfy
the heating demand, the second stage heating (Y2)
energizes switching the compressor into high stage heating
through energizing an internal solenoid valve inside the
scroll compressor and switching the indoor fan into high
stage. The auxiliary or back up heat is controlled by a third
stage (W2). If the demand is not met, W3 is energized in
case of staged heating. When heating demand is satisfied,
W3, W2 and Y2 sequentially de-energize switching the
compressor and the indoor fan into low stage heating.
When the low stage heating demand is met, Y1
de-energizes shutting the compressor, indoor fan and the
outdoor fan.
Scroll Recycle Delay timer
The defrost board is equipped with a recycle delay timer
which will delay the start of the compressor for 5 minutes in
the event of a power interruption. This sequences power
throughout the system and prevents possible reverse
rotation of the scroll compressor. The output of the timer
controls the compressor contactor via a normally open
contact of K3 (T2). The timer starts the delay cycle when the
compressor is turned off by removal of "Y." If application of
"Y" occurs before the timer has expired, the compressor
contactor will not be energized until the timer has expired.
CONTINUOUS FAN OPERATION
With the continuous Indoor fan option selected on the
thermostat, G is continuously energized. Incase of 024 -
042 units, the selected airflow setting is provided. Incase of
048 units, the system runs low stage (Y1) airflow for
continuous fan operation.
Defrost Mode
On a call for defrost:
When the defrost sensor closes in the heating mode, there
is a 30, 60, 90 or 120 minute delay before the defrost mode
begins. This delay is selected by the position of the
dipswitches on the defrost board. Defrost interval timing
can be configured by selection switch 1 and 2 on the
dipswitch per the following table: See Figure 7.

Turn off electric power supply at disconnect switch or
service panel before removing any access or service
panel from unit.
The annual inspection should include cleaning as required
to ensure efficient operation of the unit. To simplify access,
remove all access panels and the top from the unit if
possible.
Condenser Fan Motor
Note: The condenser fan motor is permanently lubricated.
No further lubrication is required. Do not attempt to
lubricate the condenser fan motor.
Clean the surrounding area and the condenser and
evaporator coils. Use caution to avoid damage to coil fins.
BLOWER MOTOR ACCESS
Refer to Figure 1 for blower motor access panel and
compartment.
1. Remove the blower access panel
2. Remove the three screws securing the blower motor
housing. If unit has a support bracket, remove the two
screws securing the bracket.
3. Remove the two red wires attached to the limit
switchand remove the limit switch.
Motor removal and replacement
This method is required to replace or repair blower wheel,
blower housing, or any unreachable components behind
blower assembly.
1. Remove all screws around rim of unit top, (except
screws which are inaccessible because of proximity to
structure).
2. Raise unit top at corner of unit closest to blower at least
2" and place a sturdy brace at least 2" thick between top
and unit corner. A 2X4 piece of wood is ideal for this.
3. Disconnect all wires from housing and slide housing out
of unit. Reverse this process to reinstall.
Circulating Air Blower
Visually inspect the blower wheel for accumulations of dirt
or lint. Clean the compartment and the blower wheel. If
accumulation is excessive on blower wheel, or does not
easily remove, it will be necessary to remove the blower
assembly.
Note: The blower motor is permanently lubricated. No
further lubrication is required. Do not attempt to lubricate
the blower motor.
