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 nishing 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, the use the electroprobe and
multimeter to perform an electrical leakage
check. Turn o the unit immediately if
leakage happens. Try and evaluate di erent
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.
