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.

(For method of using a manifold valve, refer to its operation manual.)

1. Completely tighten the flare nuts, A, B, C, D, valve charge
