Pridiom Condenser Installation Manual - Manual (Page 31)

Perform the electric safe check after
completing installation:
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
grounding resistance tester. Make sure the
grounding resistance is less than 4
.
3. Electrical leakage check (performing during
test running)
During test operation after finishing installation,
the serviceman can use the electroprobe and
multimeter to perform the electrical leakage
check. Turn off the unit immediately if leakage
happens. Check and find out the solution
ways till the unit operate properly.

CAUTION
Electrical safety check
Gas leak check
1. Soap water method:
Apply a soap water or a liquid neutral
detergent on the indoor unit connection
or outdoor unit connections by a soft
brush to check for leakage of the
connecting points of th piping. If bubbles
come out, the pipes have leakage.
