Trial operation
■ Process
Gas leakage check method
1. Soap water
Apply a soap water or a liquid neutral detergent on the indoor unit
connection and outdoor unit connections by a soft brush to check for
leakage of the connecting points of the piping. If bubbles come out,
the pipes have leakage.
2. Leak detector
Use the leak detector to check for leakage.
CAUTION:
A: Lo packed valve
B: Hi packed valve
C and D are ends of indoor unit connection.

Trial operation
■ Process
Drainage check
① Open the front panel from the indoor unit.
② To check the drainage.
Pour a glass of water on the evaporator.
Ensure the water flows through the drain hose of the indoor
unit without any leakage and goes out the drain exit.

Trial operation
■ Process
Test running
When the ambient temperature is too low (lower than 17OC), the unit cannot be controlled by the remote controller to run
at cooling mode, manual operation can be taken. Manual operation is used only when the remote controller is disable or
maintenance necessary.
Hold the panel sides and lift the panel up to an angle until it remains fixed with a clicking sound.
Press the Manual control button to select the AUTO or COOL, the unit will operate under Forced AUTO or COOL mode.
The test operation should last about 30 minutes.
Perform test operation after completing gas leak check at the flare nut
connections and electrical safety check.
Check that all tubing and wiring have been properly connected.
Check that the gas and liquid side service valves are fully open.
1. Connect the power, press the ON/OFF button on the remote controller
to turn the unit on.
2. Use the MODE button to select COOL, HEAT, AUTO and FAN to check
if all the functions works well.
