9 Electrical and Gas Leak Checks
9.1 Electrical Safety Checks
After installation, confi rm that all electrical wiring is installed in accordance with
local and national codes / regulations, and according to the Installation Manual. All
testing must be performed by a licensed electrician.
Before test run
Check grounding work
Measure grounding resistance by visual detection and with grounding
resistance tester. Grounding resistance must be less than 0.1Ω.
This may not be required for some locations. Refer to local code
requirements.
During test run
Check for electrical leakage
During the Test Run , use an electroprobe and multimeter to perform a
comprehensive electrical leakage test. If electrical leakage is detected,
turn off the unit immediately and call a licensed electrician to find and
resolve the cause of the leakage.
This may not be required for some locations in the US.
WARNING: Risk of electric shock

9.2 Gas Leak Checks
There are two diff erent methods to check for gas leaks.
Soap and Water Method

points on the indoor unit and outdoor unit. The presence of bubbles indicates a
leak.
