Install Checklist

1. Motor Inspection
*
A. Verify that the model, hp or kW, voltage, phase and hertz on the motor nameplate match the
installation requirements.
*
B. Check that the motor lead assembly is not damaged.
*
C. Measure insulation resistance using a 500 or 1000 volt DC megohmmeter from each lead wire to the
motor frame. Resistance should be at least 200 megohms without drop cable.
*
D. Keep a record of motor model number, hp or kW, voltage, and serial number (S/N).
(S/N is stamped in shell above the nameplate. A typical example, S/N 07A18 01-0123)
2. Pump Inspection
*
A. Check that the pump rating matches the motor.
*
B. Check for pump damage and verify that the pump shaft turns freely.
3. Pump/Motor Assembly
*
A. If not yet assembled, check that pump and motor mounting faces are free from dirt, debris and uneven
paint thickness.
*
B. Pumps and motors over 5 hp should be assembled in the vertical position to prevent stress on pump
brackets and shafts. Assemble the pump and motor together so their mounting faces are in contact and
then tighten assembly bolts or nuts evenly to manufacturer specifications.
*
C. If accessible, check that the pump shaft turns freely.
*
D. Assemble the pump lead guard over the motor leads. Do not cut or pinch lead wires during assembly
or installation.
4. Power Supply and Controls
*
A. Verify that the power supply voltage, Hertz, and kVA capacity match motor requirements.
*
B. Verify control box hp and voltage matches motor (3-wire only).
*
C. Check that the electrical installation and controls meet all safety regulations and match the motor
requirements, including fuse or circuit breaker size and motor overload protection. Connect all metal
plumbing and electrical enclosures to the power supply ground to prevent shock hazard. Comply with
national and local codes.
5. Lightning and Surge Protection
*
A. Use properly rated surge (lightning) arrestors on all submersible pump installations. Motors 5 hp and
smaller, which are marked “Equipped with Lightning Arrestors”, contain internal arrestors.
*
B. Ground all above ground arrestors with copper wire directly to the motor frame, or to metal drop pipe or
casing which reaches below the well pumping level. Connecting to a ground rod does not provide good
surge protection.
6. Electrical Drop Cable
*
A. Use submersible cable sized in accordance with local regulations and the cable charts. See pages 11 and
16-21. Ground motor per national and local codes.
*
B. Include a ground wire to the motor and surge protection, connected to the power supply ground if
required by codes. Always ground any pump operated outside a drilled well.
7. Motor Cooling
*
A. Ensure at all times that the installation provides adequate motor cooling; see page 6 for details.
