TEST RUNNING
Electric safety check
Perform the electric safety check after completing the installation:
1. Insulated resistance
The insulated resistance must be more than 2 MΩ.
2. Grounding work
After finishing grounding work, measure the grounding resistance by visual detection and grounding resistance tester.
3. Electrical leakage check (performing during test running)
During test operation after finishing installation, the serviceman can use the electro probe and multimeter to perform the
electrical leakage check. Turn off the unit immediately if leakage happens. Check and seek for a solution until the unit operates
properly.
Gas leak check
1. Soap water method
Apply soap water or a liquid neutral detergent on the indoor unit connection or outdoor unit connections using a soft brush to
check for leakage of the connecting points of the piping. If bubbles come out, the pipes are leaking.
2. Leak detector
Use the leak detector to check for leakage.
