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
When a three-prong grounded plug is used:
Use the megohmmeter to measure the motor insulation resistance
between the grounding prong and each one of the two power prongs.
When connection wires are used:
With the megohmmeter, measure the insulation resistance between
the ground wire (Green) and each one of the two power wires.
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 the Periodic Maintenance table.
Precautions in Installation
When installing the pump, pay close attention to its center of gravity
and weight. If it is not lowered into place correctly, it may fall and be
damaged or cause injury.
When transporting the machine by hand, be sure to employ manpower
commensurate with the weight of the machine. To avoid back injury
when lifting the machine, 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 current leakage, shock, or fire.
2.3.1 Avoid dropping the pump or other strong impact. Lift the pump by
holding it firmly with the hands or by attaching a rope or chain to the
lifting handle.
Note: On cable assembly handling, see Electrical Wiring.
Avoid dry operation, which will not only lower performance but can
cause the pump to malfunction, leading to electrical leakage and
shock.
