WINTER HEATING SUMMER COOLING

1. Outdoor air enters the heat pump.

2. The cold, heat-transfer section (outdoor coil) extracts the heat from the air as the refrigerant evaporates from a liquid to a cold gas.

3. The refrigerant, compressed to a hot gas by the heat pump, carries the heat to the heattransfer section (indoor coil).

4. The hot, heat-transfer section (indoor coil) releases the heat as the refrigerant condenses

from a gas to a liquid.

5. The blower circulates the heat throughout the home via the supply duct.

6. The refrigerant returns to the outdoor coil and evaporates once again to absorb more heat.

1. Indoor air enters the return air duct.

2. The cold, heat-transfer section (indoor coil) extracts the heat from the air as the refrigerant evaporates from a liquid to a cold gas.

3. The refrigerant, drawn to the heat pump and compressed to a hot gas, carries the heat outdoors.

4. The hot, heat-transfer section (outdoor coil) releases the heat as the refrigerant condenses from a gas to a liquid.

5. The heat pump (outdoor fan) discharges the heat to the outside air.

6. The refrigerant returns to the indoor coil and evaporates once again to absorb more heat.

It is the sole responsibility of the homeowner to make certain that heat pump has been correctly set up and adjusted to operate properly.

2. Resetting circuit breakers or other switches.

3. Adjusting or calibrating of thermostat.

The Manufacturer warrants the heat pump to be free from defects in material or workmanship for a period of one year. We will not be responsible for any costs found necessary to correct problems due to improper setup, improper installation, adjustments, improper operating procedure on the part of the user, etc.

To avoid misunderstandings at a later date, carefully review these responsibilities with your dealer or service company.

The heat pump system will heat and cool your home and save your energy dollars.

Some specifi c examples of service calls which are not included in the limited warranty are:

1. Correcting wiring problems in the electrical circuit supplying the heat pump.

During the summer, a heat pump cools a house by absorbing heat from within the house and exhausting it outdoors. During the winter, a heat pump heats a house by absorbing heat outdoors and exhausting it indoors. This is an effi cient heating means because you pay for “moving” heat from outdoors to indoors, but do not pay to generate the heat.

OPERATING INSTRUCTIONS

To Operate Your Heat Pump For Cooling —

1. Set the thermostat system switch to COOL and the thermostat fan switch to AUTO. See

Figure 1.

2. Set the thermostat temperature selector to the desired cooling temperature. The outdoor unit fan, the indoor blower, and the compressor will all cycle on and off to maintain the indoor temperature at the desired cooling level.

Defrost — During cold weather heating operation, the outdoor unit will develop a coating of snow and ice on the heat transfer coil. This is normal and the unit will periodically defrost itself. During the defrost cycle, the outdoor fan will stop, while the compressor continues to run and heat the outdoor coil, causing the snow and ice to melt.

During defrost, there may be some steam rise from the outdoor unit as the warm coil causes some melted frost to evaporate.

1. Set the thermostat system switch for HEAT and the thermostat fan switch to AUTO. See

Figure 1.

SPECIFICATIONS

2. Set the thermostat temperature selector to the desired heating temperature. The outdoor unit fan, the indoor blower, and the compressor will all cycle on and off to maintain the indoor temperature at the desired heating level.

Single Package Heat Pumps are designed for outdoor rooftop or ground level slab installations.

The units are shipped ready for horizontal duct connections and are easily converted for down fl ow applications.

NOTE: If the thermostat temperature level is re-adjusted, or if the thermostat system switch is re-positioned, the outdoor unit fan and the compressor may not start immediately. A protective timer circuit holds the compressor and the outdoor fan off for approximately six minutes following a previous operation or the interruption of the main electrical power.

All models are shipped from the factory with the following:

1. Zero clearance to combustibles

2. Multi-tap fi xed -torque blower.

3. Blower Speed Relay.

4. Horizontal or Down fl ow duct connections.

Emergency Heat — Some thermostats will include a system switch position termed EM HT or AUX HT, etc. This is a back-up heating mode available if supplemental electrical resistance heat is installed. With the system switch set to

EM HT, etc., the compressor and outdoor fan will be locked off and supplemental heat (electric resistance heating) will be used as a source of heat. Sustained use of electric resistance heat in place of the heat pump will result in an increase in electric utility costs.

The unit dimensions are shown in Figure 2.

Optional field-installed electric heater kits are available in 5,8,10,15, and 20Kw heating capacities. A separate installation instruction document for the electric heaters and their application accompanies this one.

(or the circuit breaker when the fi eld installed circuit breaker kits are used) inside the control compartment. Use only copper wire for the line voltage power supply to this unit. Use proper code agency listed conduit and a conduit connector for connecting the supply wires to the unit and for obtaining proper grounding. Grounding may also be accomplished by using the grounding lug provided in the control box.

Low Voltage Connections

Room Thermostat — Several options are available for a room thermostat depending on the accessories installed with the unit. Select a thermostat which operates in conjunction with the installed accessories. The thermostat should be mounted about fi ve feet above the ground on an inside wall. The thermostat should be kept away from drafts, slamming doors, lamps, direct sunlight, or in line with the supply air fl ow.

To install the thermostat:

1. Position the sub base on an inside wall and mark the mounting holes and thermostat cable openings.

2. Cut out the cable opening and route the thermostat cable from the unit’s low voltage compartment to the thermostat location.

The thermostat cable is supplied by the installer.

3. Connect the cable leads to the sub base or thermostat terminals and to the unit’s low voltage pigtails as shown in Figure 8.

A system wiring diagram is also provided on the inside of the control panel cover.

4. Secure sub base or thermostat to the wall using screws provided with the thermostat.

5. If sub base is used, install the correct thermostat housing to sub base.

6. Refer to thermostat instruction sheet for complete detailed mounting information.

Defrost Cycle Timer — The defrost cycle timer controls the time interval of the hot gas defrost after the defrost sensor closes. It is located in the lower left corner of the defrost control board on the low voltage side of the control box. Three interval settings are available: 30 minutes, 60 minutes, and 90 minutes. Time setting selection is dependent on the climate where the unit is being installed.

Example 1. Dry climate of Southern Arizona.

A 90 minute setting is recommended.

Example 2. Moist climate of Seattle,

Washington. A 30 minute setting is recommended.

DEFROST CONTROL BOARD OPERATION

AND TESTING

1. Terminals “R”-”C” must have 24±V present between them in order for the time delay and defrost sequences to be operational.

2. Jumper the “T2”-”DFT” test pins. This will indicate to the board that the defrost T-stat is closed(if the compressor is running).

Defrost T-stat is closed at 32° or below and is open at 68° or above. But it’s state is unknown if the temperature is between 32°F and 68°F. The defrost thermostat tells the board whether a defrost cycle needs to be started or terminated. With the DFT closed the unit will run for 30/60/90 minutes in heat mode and then defrost the outdoor coil. The defrost will turn off the outdoor fan, turn on the compressor and raise the coil temperature to

68°F. This will open the DFT and terminate the defrost. If the DFT does not open the defrost will end after 10 minutes.

3. Defrost board speed-up. With compressor running in heat mode, next jump the “Test” pin to “C” on terminal strip. This will initiate a defrost test in 5, 10 or 15 seconds (This is determined by the 30, 60 or 90 minute defrost pin settings. The factory setting will be 30 minutes). Note that this will bypass the compressor off delay when the unit goes into defrost test and if left in defrost test, the delay will be bypassed when the test is terminated by the processor. If the jumper is removed before the test is over the processor will perform the remainder of a normal defrost.

See step 2 above.

To set the cycle timer, place the timing pin on the defrost control board to the desired time interval post.

Note: All units are shipped from the factory with the default time setting of 30 minutes.

Field Installed Electric Heat — These Single

Package Heat Pumps are designed to allow optional electric heat to be fi eld installed as required by the building’s particular heating load.

The options available for each unit are shown in the heater kit installation instructions. As noted in the instructions, a fi eld installed circuit breaker kit is available as a means of electrical disconnect for the unit.

Install the heater kits as directed by the installation instructions that come as part of the heater kit.

Follow all cautions and warnings as directed.

4. Remove the jumpers.

Note: The delay/no-delay pin concer ns compressor operation during defrosts. The default setting is delay. Reciprocating compressors should only use this setting in conjunction with an approved hard start kit. Scroll compressors that have noise issues while going into or coming out of defrost should use this 30 second delay to reduce the defrost noise. To switch from no-delay to delay remove the pin from the “no-delay” pin location and shift it to the “delay” pin location.

Speed up changes:

Manually initiating a defrost will cause the compressor to run continually when entering defrost.

Normal defrost operation:

To test normal defrost operation when the temperature is above 35°F, jumper “R” to

9

10

“DFT” on the 624656 board and allow the unit to run for 30 minutes. Defrost will continue until the “R” to “DFT” jumper is removed or for 10 minutes. Remove the jumper.

The 5 minute time delay feature can be shortened

1 time to 1 second by jumping the “Test” to “C” terminal. Remove the jumper and repeat as desired.

• Verify that the outdoor fan turns freely.

• Verify that the power supply branch circuit overcurrent protection is sized properly.

• Verify that the thermostat is wired correctly.

The thermostat function switch should be set to “Off’ and the thermostat fan switch should be set to “Auto.”

Note: If jumper is left on the “Test” to “common” pins permanently, the defrost cycle will become inoperable.

Start-Up Procedure

Close all electrical disconnects to energize the system.

Defrost Test Procedure for 624656

1. Jumper “T2” to “DFT” at the test terminals.

2. With unit running in heat mode, short the

“TEST” terminal to the common terminal near it. This will speed up the board and cause it to enter defrost mode in 5/10/15 seconds depending on the defrost time selection.

Compressor delay will not function during speed-up.

3. This test will end in 5 seconds if the “TEST”common short is not removed.

4. Remove both the short and the “T2” to “DFT” jumper to terminate the defrost cycle. The

30 second compressor delay should operate normally.

5. Test is complete, reset thermostat to home owner preference.

START UP AND SYSTEM CHECK

Pre-Start Check List

WARNING:

If the unit is equipped with a crankcase heater, allow 24 hours prior to continuing the start up procedures to allow for heating of the refrigerant compressor crankcase.
