Measure grounding resistance by visual
detection or with a grounding resistance tester.
Grounding resistance must be less than 4Ω.
Note: This may not be required in some locations.

and multi-meter 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.
Note: This may not be required in some locations.
