9. Test Run
9.1 Things to Note Before Test Run
1) Indoor and outdoor units are properly installed;
2) Piping and wiring are correct;
3) No leakage from the refrigerant piping system;
4) Water discharge is smooth;
5) Insulation is complete;
6) Grounding line has been properly connected;
7) Piping length, and amount of refrigerant filled have been recorded;
8) The voltage of the power supply is the same as the rated voltage
of the air conditioner;
9) No obstacles at the air inlet and outlet of the indoor and outdoor
units;
10) Cut-off valves for the gas and liquid ends are opened;
11) Connect to the power supply to let the air conditioner warm up first.
9.2 Test Run
Use wired/remote controller to control and operate the air conditioner
in the cooling mode. Check the following items according to the
manual. If there is any fault, troubleshoot by referring to the section
"Air Conditioner Errors and Causes" in the manual.
9.2.1 Indoor unit
1) Wired/remote controller switch is operating normally;
2) Function keys of the wired/remote controller are operating normally;
3) Room temperature regulation is normal;
4) LED indicator is on;
5) Key for manual operation is normal;
6) Water discharge is normal;
7) No vibration and strange sounds during operation;
9.2.2 Outdoor unit
1) No vibration and strange sounds during operation;
2) If the wind, noise and condensation affect the neighbours;
3) Any refrigerant leakage.
means 1
Once the power is connected, when the unit is turned on or
started immediately after the unit is turned off, the air conditioner
has a protective function which delays the start of the
compressor by 3 minutes.
