Perform the electric safe check after completing installation:
1. Grounding work 
    After finishing grounding work, measure the grounding resistance by visual detection and 
    grounding resistance tester. Make sure the grounding resistance is less than 4

Ω

2. Electrical leakage check (performing during test running)
    During test operation after finishing installation, the serviceman can use the electroprobe 
    and multimeter to perform the electrical leakage check. Turn off the unit immediately if 
    leakage happens. Check and find out the solution ways till the unit operate properly.

  Gas leak check

1. Soap water method:
     Apply a soap water or a liquid neutral detergent 
     on the indoor unit connection or outdoor unit 
     connections by a soft brush to check for leakage 
     of the connecting points of th piping. If bubbles
     come out, the pipes have leakage.
2. Leak detector

Use the leak detector to check for leakage.

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

3. When the ambient temperature is too low(lower than 17 C), 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(see User Manual for details).
4.  The test operation should last about 30 minutes.
