Critical Pressure
Do not use the pump in an area where the water pressure exceeds the
values given below, as it may damage the pump, or cause a short or
electrical shock.
Preparing for Installation
Before installing the pump at a work site, you will need to have the
following tools and instruments ready:
• Insulation resistance tester (megohmmeter)
• AC voltmeter
• AC ammeter (clamp-on type)
• Bolt and nut tighteners
• Power supply connection tools (screwdriver or box wrench)
Note:
Please also read the instructions that come with each of the test
instruments.
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: 20M
W
or greater
Note: The reference insulation resistance (20M
W
or greater) is the
value when the pump is new or has been repaired. For the reference
value after installation, see Maintenance and Inspection.
