9.3 Safety and leakage check

Electrical safety check
Perform the electrical safety check after completing installation. Cover the following areas:
1. Insulated resistance
The insulated resistance must be more than 2M.
2. Grounding work
After finishing grounding work, measure the grounding resistance by visual detection and using the
grounding resistance tester. Make sure the grounding resistance is less than 4.
3. Electrical leakage check (performing during test while unit is on)
During a test operation after completed installation, use the electroprobe and multimeter to
perform an electrical leakage check. Turn off the unit immediately if leakage happens. Try and
evaluate different solutions until the unit operates properly.
Gas leak check
1. Soap water method:
Apply a soap-water solution or a liquid neutral detergent on the indoor unit connection or outdoor
unit connections with a soft brush to check for leakage of the connecting points of the piping. If
bubbles emerge, the pipes are experiencing leakage.
2. Leak detector
Use the leak detector to check for leakage.
