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 (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.
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.
Precautions During Installation
When installing the pump, pay close attention to its center of gravity
and weight. If it is not suspended properly, it may fall and be damaged
or cause injury.
When transporting the pump manually, be sure to employ manpower
commensurate with the weight of the pump. To avoid back injury when
lifting the pump, bend the knees to pick it up rather than bending your
back only.
Do not under any circumstances install or move the pump by
suspending it from the cable assembly. The cable may be damaged,
causing electrical leakage, shock, or fire.
4.3.1 This pump series is offered with a variety of discharge fittings. Please
refer to the BOM Product Matrix in the Parts Section to identify the type
of discharge fitting used on your pump. Follow procedures noted
below to assure a proper discharge connection.
Threaded Discharge Fitting (BSP) –
Tighten hose coupling or discharge pipe securely and with proper
gaskets.
Quick Disconnect Coupling (QD) –
Assure coupling is tightened securely to pump discharge fitting and
