Test Operation
System Checks
1. Conceal refrigerant pipes where possible.
2. Make sure drain hose slopes downward along entire length at
a slope of 1/4”(inch) per ‘(foot).
3. Ensure all refrigerant pipes and connections are properly
insulated.
4. Fasten pipes to outside wall, when possible.
5. Seal and weatherproof wall hole which the interconnecting
wires and refrigerant pipes pass through.
Perform test operation after completing gas leak and electrical
safety check.
1. Turn on electrical disconnect to outdoor unit.
2. Push the “ON/OFF” button on Remote Controller to begin
testing, or if remote is not available press auto start switch on
indoor unit.
3. Push MODE button, select COOLING, HEATING, FAN mode to
conrm all functions.
Indoor Unit
1. Do all Remote controller’s buttons function properly?
2. Do the display panel lights work properly?
3. Does the swing louver function properly?
4. Does the drain work?
Outdoor Unit
1. Push the mode button to COOL and adjust the room
setting to 61 °F. Wait up to 3 minutes for compressor time delay.
Does compressor and outdoor fan turn on in cooling mode?
2. Push the mode button to HEAT and adjust the room
setting to 85 °F( Wait up to 3 minutes for compressor time delay.
Does compressor and outdoor fan turn on in heat mode?

Preheat
At the beginning of the HEATING operation, the airflow from the indoor
unit is discharged 2-5 minutes later.
Defrost
In HEATING operation the appliance will defrost (de-ice)
automatically to raise efficiency. This procedure usually
