Inspections Before Test Run
Do the following checks before test run.
TEST OPERATION
Description Inspection method
Electrical safety
inspection
• Check whether the power supply voltage complies with specification.
• Check whether there is any wrong or missing connection between the power
lines, signal line and earth wires.
• Check whether the earth resistance and insulation resistance comply with
requirements.

• Confirm the safety of outdoor unit, mounting plate and indoor unit installation.
• Confirm that the valves are fully open.
• Confirm that there are no foreign objects or tools left inside the unit.
• Complete installation of indoor unit air inlet grille and panel.
Refrigerant leakage
detection
• The piping joint, the connector of the two valves of the outdoor unit, the valve
spool, the welding port, etc., where leakage may occur.
• Foam detection method:
Apply soapy water or foam evenly on the parts where leakage may occur, and
observe whether bubbles appear or not, if not, it indicates that the leakage
detection result is safe.
• Leak detector method:
Use a professional leak detector and read the instruction of operation, detect at
the position where leakage may occur.
• The duration of leak detection for each position should last for 3 minutes or
more;
If the test result shows that there is leakage, the nut should be tightened and
tested again until there is no leakage;
After the leak detection is completed, wrap the exposed pip connector of indoor
unit with thermal insulation material and wrap with insulation tape.
