CLEARANCES
CONDENSATE DRAIN
All units require certain clearances for proper operation and
service. Refer to Figure 3 for the clearances required for
combustion, construction, servicing and proper unit operation.
A condensate trap is required to be installed in the condensate
drain. The plumbing must conform to local codes. Use a sealing
compound on male pipe threads. Install the condensate drain
line (3⁄4" NPTF) to spill into an open drain.
WARNING: Do not permit overhanging structures or shrubs to
obstruct the condenser air discharge outlet.
SERVICE ACCESS
DUCT WORK
Access to all serviceable components is provided by the following removable panels:
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:
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 later).
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.
3. Seal duct covers with silicone caulk.
Downflow units must have an “L”-shaped supply duct without
any outlets or registers located below the outlet of the unit.
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 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.
CAUTION: 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.
NOTE: Be sure to note supply and return openings.
Refer to Figure 4 for information concerning rear and bottom
supply and return air duct openings.
FILTERS
Single phase units are shipped without a filter and is the responsibility of the installer to secure a filter in the return air ductwork
or install a Filter/Frame Kit (1FF0114).
A filter rack and a 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 is delivered by the
blower, decreasing your unit’s efficiency and increasing operating costs and wear-and-tear on the unit and controls.
Filters should be checked monthly especially since this unit is
used for both heating and cooling.
Unitary Products Group
• Blower service access
• Electrical/Filter access
• Compressor service access
Refer to Figure 3 for location of these access panels and
minimum clearances.
THERMOSTAT
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 Figure 2.
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 3.
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.
Refer to Figure 2 for typical field wiring and to the appropriate unit
wiring diagram for control circuit and power wiring information.
COMPRESSORS
Units are shipped with compressor mountings factory-adjusted
and ready for operation.
CAUTION: Do Not loosen compressor mounting bolts.

SEQUENCE OF OPERATION
Anti-short Cycle Timer
This unit has an anti-short cycle timer built in to the defrost
control. This timer will not permit the compressor to start within
five minutes after the completion of the last cycle or power
interruption. To bypass the anti-short cycle feature, short the
“TEST” pins together for 2 seconds.
The following sequences of operation are based on using a
standard single-stage heat pump thermostat.
Cooling Operation
(B1HH018 — 048 and 575-volt 060 Models with Standard PSC Indoor
Motor)
WITH POWER TO UNIT AND THERMOSTAT IN COOLING
MODE.
1. If the fan switch on the thermostat is in the “ON” position,
the 24 volts at “G” will energize the “K1” relay on the fan
control board, close the “K1” relay contacts, and energize
the indoor blower motor. If the fan switch on the thermostat
is in the “AUTO” position, the blower will operate only when
there is a call for cooling by the thermostat.
2. On a call for cooling, the thermostat will send 24 volts to “Y”
and "O" on the fan control board. After the anti-short cycle
period is complete,The 24 volt signal will energize contactor
“M1”, and the reversing valve solenoid. Power will be supplied to the compressor and outdoor fan motor, and the
reversing valve will switch to the cooling position. If the fan
switch on the thermostat is on the “AUTO” position, the fan
control will energize the indoor blower.
3. When the demand for cooling has been satisfied, the 24
volt “Y” signal is removed and the “M1” contactor will be
de-energized. If the fan switch on the thermostat is in the
“ON” position, the indoor blower will continue to run. If the
fan switch is in the “AUTO” position, the “K1” relay will open
and de-energize the indoor blower motor after a 60 second
delay,
Heating Operation
(B1HH018 — 048 and 575-volt 060 Models with Standard PSC Indoor
Motor)
WITH POWER TO UNIT AND THERMOSTAT IN HEATING
MODE.
1. If the fan switch on the thermostat is in the “ON” position,
the 24 volts at “G” will energize the “K1” relay on the fan
control board, close the “K1” relay contacts, and energize
the indoor blower motor. If the fan switch on the thermostat
is in the “AUTO” position, the blower will operate only when
there is a call for heating by the thermostat.
2. On a call for heating, the thermostat will send 24 volts to
"Y" on the fan control board. After the anti-short cycle period
is complete, the 24 volts signal will energize contactor coil
“M1” and power will be supplied to the compressor and
outdoor fan motor. The reversing valve will remain in the
heating position. If the fan switch on the thermostat is in the
“AUTO” position, the fan control will energize the indoor
blower.
3. For units equipped with supplementary electric heat, if the
heat pump cannot meet the demand, the thermostat “W”
will send 24 volts to “W2” on the fan control board. This
signal will also be sent through the defrost control terminals
“W” and “W1/66” and back to the fan control “W1”. This 24
volt signal will energize all stages of electric heat.
4. When the heating demand is satisfied, the electric heat will
be de-energized when the 24 volt “W” signal is removed,
and the “M1” contactor will be de-energized when the 24
volt “Y” signal is removed. If the fan switch on the thermostat
is in the “ON” position, the indoor blower will continue to run.
If the fan switch is in the “AUTO” position, the “K1” relay will
Unitary Products Group
open and de-energize the indoor blower motor after the
appropriate time delay.
Defrost Operation
The minimum time between defrosts can be field selected at
30, 60 or 90 minutes. The default time is 90 minutes if the jumper
is not installed.
Defrost will initiate when the defrost sensor, located on the
outdoor coil, senses a temperature below 31°F and when the
time since the last defrost is greater than the selected time on
the defrost control. The defrost cycle terminates when either
the defrost sensor reaches 55°F or the unit has been in defrost
mode for 10 minutes. If the room thermostat opens during
defrost, the unit will resume operation in defrost when the
thermostat re-closes.
During the defrost mode, the defrost control will provide a 24
volt signal from terminal “W1/66” to the fan control terminal
“W1”. This signal will energize electric heat stage 1, if the unit
is so equipped.
For trouble shooting purposes, the defrost cycle can be manually initiated by shorting the “TEST” pins together for 5 seconds.
Defrost will terminate normally during the “TEST” mode.
Heat Pump Safety Switch Operation
If the unit is equipped with the field installed upgrade safety
package, the refrigeration system will be protected against high
or low refrigerant pressure and low indoor coil temperature. If
any of these three safety switches opens, the unit will be shut
off for the 5 minute anti-short cycle time. Once this has expired,
a six hour elapsed run timer begins. If a second opening of a
safety switch occurs during this six hour period, the compressor
will be locked out.
Resetting the lockout function is accomplished by;
1. Removing power from the control’s thermostat 1st stage (Y)
input for a time not to exceed 5 seconds (ON-OFF-ON).
2. Removing power from “R” for more than 2 seconds.
3. Shorting the “TEST” pins together for more than 2 seconds.
Electric Heat Limit Switch Operation
The limit switch responds to over temperature conditions in the
air duct. Opening of 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 during this period the control "sees" another
limit cycle, 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 the state.
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.
COOLING OPERATION
(B1HH060 with ECM indoor motor)
1. When the fan switch on the thermostat is in the “ON”
position, the 24 volts at “G” will bring on the indoor blower
motor at the cooling airflow. When 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. On a call for cooling, the thermostat sends 24 volts to “Y”
and “O” on the fan control and defrost control boards. The
reversing valve solenoid is energized, and after the antishort cycle period is complete contactor coil M1 is ener15

motor, and the reversing valve switched to the cooling
position. When the fan switch on the thermostat is in the
“AUTO” position the indoor blower motor is energized at the
cooling airflow.
complete, the 24 volt signal energizes contactor coil M1 and
power is supplied to the compressor and outdoor fan motor.
The reversing valve remains in the heating position. When
the fan switch on the thermostat is in the “AUTO” position,
the indoor blower is energized at the heating airflow.
3. When the demand for cooling has been satisfied, the 24
volt “Y” signal is removed, and the M1 contactor is de-energized. When the fan switch on the thermostat is in the
“ON” position, the indoor blower motor continues to run. If
the fan switch is in the “AUTO” position. the indoor motor
ramps down over a 30-second period.
3. For units equipped with supplementary electric heat, when
the heat pump cannot meet the demand, the thermostat
“W” sends 24 volts to “W2” on the fan control board. This
signal also is sent through the defrost control terminals “W”
and “W6” and back to the fan control “W1”. The 24 volt signal
energizes all stages of electric heat.
HEATING OPERATION (B1HH060 with ECM indoor motor)
4
1. When the fan switch on the thermostat is in the “ON”
position, the 24 volts at “G” brings on the indoor blower
motor at the heating flow. When the fan switch on the
thermostat is in the “AUTO” position, the blower operates
when there is a call for heating by the thermostat.
2. On a call for heating, the thermostat sends 24 volts to “Y”
on the fan control board. After the anti-short cycle period is
When the heating demand is satisfied, the electric heat is
de-energized when the 24 volt “W” signal is removed, and
the M1 contactor is de-energized when the 24 volt “Y” signal
is removed. When the fan switch on the thermostat is in the
“ON” position, the indoor blower continues to run. When the
fan switch is in the “AUTO” position, the indoor blower motor
ramps down over a 15-second period.
Please refer to Tables 21 and 22 for more information.
SECURE OWNER’S APPROVAL: When the system is functioning 1/6 properly, secure the owner’s approval. Show him
the location of all disconnect switches and the thermostat. Teach him how to start and stop the unit and how to adjust temperature
settings within the limitations of the system.
