SECTION IX: SYSTEM OPERATION

For more information on the control operation, refer to the “OPERA-
TION INSTRUCTIONS - DEMAND DEFROST CONTROL BOARD”
publication.

REQUIRED CONTROL SETUP

1. Consult system wiring diagram to determine proper thermostat wir-

ing for your system.

2. Verify that the factory set the defrost curve selection jumper at the

number “1” pin position on the defrost control board.

3. If hot heat pump configuration is desired, change HOT HEAT PUMP

jumper to ON position. This setting MUST be set on the defrost
board.

4. If installation includes a fossil fuel furnace, change FUEL jumper to

ON position. This setting MUST be set on the defrost board.

5. Set low temperature cutout (LTCO), balance point (BP), switch point

(SP), and Y2 Lock jumpers as desired. These settings may be mod-
ified by communicating thermostat.

6. Verify proper system functionality. Confirm room thermostat opera-

tion including fault code display capability.

7. Upon completion of installation, verify that no fault codes are stored

in memory. Clear the fault code memory if necessary.

SECTION X: INSTRUCTING THE OWNER

Assist owner with processing warranty cards and/or online registration.
Review Owners Guide and provide a copy to the owner and guidance
on proper operation and maintenance. Instruct the owner or the opera-
tor how to start, stop and adjust temperature setting.

When applicable, instruct the owner that the compressor is equipped
with a crankcase heater to prevent the migration of refrigerant to the
compressor during the OFF cycle. The heater is energized only when
the unit is not running. If the main switch is disconnected for long peri-
ods of shut down, do not attempt to start the unit until 8 hours after the
switch has been connected. This will allow sufficient time for all liquid
refrigerant to be driven out of the compressor.

The installer should also instruct the owner on proper operation and
maintenance of all other system components.

MAINTENANCE

1.

Dirt should not be allowed to accumulate on the outdoor coils or
other parts in the air circuit. Clean as often as necessary to keep
the unit clean. Use a brush, vacuum cleaner attachment, or other
suitable means.

2.

The outdoor fan motor is permanently lubricated and does not
require periodic oiling.

3.

If the coil needs to be cleaned, it should be washed with Calgon
Coilclean (mix one part Coilclean to seven parts water). Allow
solution to remain on coil for 30 minutes before rinsing with clean
water. Solution should not be permitted to come in contact with
painted surfaces.

4.

Refer to the furnace or air handler instructions for filter and blower
motor maintenance.

5.

The indoor coil and drain pan should be inspected and cleaned
regularly to prevent odors and assure proper drainage.

SUBCOOLING CHARGE TABLE IS ON THE UNIT RATING PLATE.

The following steps must be taken at the time of installation to insure
proper system operation.
