CLEARANCES

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.

WARNING: Do not permit overhanging structures or shrubs to obstruct the condenser air discharge outlet.

DUCT WORK

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.

511.18-N2Y

CONDENSATE DRAIN

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.

SERVICE ACCESS

Access to all serviceable components is provided by the following removable panels:

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.

NOTE: 1. Deduct these resistance values from the available external static pressure shown in the respective Blower Performance Table.

2. The pressure thru the economizer is greater for 100% outdoor air then for 100% return air. If the resistance of the return air duct system is less then 0.25 IWG, the unit will deliver

less CFM during full economizer operation.

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.

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.

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.

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.

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.

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.

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,

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;

Heating Operation

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.

(B1HH018 — 048 and 575-volt 060 Models with Standard PSC Indoor

MODE.

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.

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

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 ener-

“AUTO” position the indoor blower motor is energized at the cooling 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.

HEATING OPERATION

(B1HH060 with ECM indoor motor)

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 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. 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.

4 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.
