6�2 Safety and leakage check
6�2�1 Electrical safety check
Perform the electrical safety check after
completing installation. Cover the following areas:
1. Insulated resistance
2. The insulated resistance must be more than
2MΩ.
3. 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 4Ω.
4. Electrical leakage check (performing during test
while unit is on).
5. During a test operation after completed
installation, the 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.
6�2�2 Gas leak checks
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.
