3.6 Checks to Make Before Installation

With the megohmmeter, measure the insulation resistance between

each of the power wires and grounding wire to verify the insulation

resistance of the motor.

Reference insulation resistance: 20MW or greater

Note: The reference insulation resistance (20MW or greater) is the

value when the pump is new or has been repaired. For the reference

value after installation, see Maintenance and Inspection.

DO NOT measure the insulation resistance with insulation resistance

tester for the following parts. It will cause damage (Model PSA 2 500).

Improper ways to measure insulation resistance

1 Between the plug prongs.

2 Between the electrodes on the level relay unit.

3 Between the electrodes on the level relay unit and the plug prongs.
