1. |
Prior to performing the maintenance
procedure ensure that the optional Main Disconnect Switch is
operating properly, the user supplied circuit breaker is in the
Off position, and that all sources of power are isolated from
the Pump Set. Proceed only after this is verified.
|
|
2. |
Check Main Disconnect Switch, door
and hinge operation.
|
|
3. |
Check cabinet mounting hardware
at feet and wall mounting flange. Tighten as necessary.
|
|
4. |
Test pumps in duplex pump sets.
Ensure both pumps are operating normally, test each pump individually,
test simultaneous operation, test alternating operation.
|
|
5. |
Check pump/motor hardware for tightness.
Pump/motor hardware for tightness. Pump/motor hardware will loosen
after normal operation due to vibration. This hardware is double
nutted, check all bolts for double nuts.
|
|
6. |
Rotate shaft by hand and check
for smooth operation. Check pump/motor coupler shown at left
for proper alignment and spacing. The Lovejoy coupler should
have approximately 1/8" clearance between coupler halves.
If this clearance is reduced or the pump and motor are not properly
aligned excessive noise and pump/motor wear will occur. Loosen
pump motor mounting hardware to realign motor/coupler. Loosen
one end of pump coupler to adjust for necessary coupler clearance.
|
|
7. |
Check all electrical terminals
and connections for tightness.
|
|
8. |
All motors are permanently lubricated
and do not require any lubrication.
|
|
9. |
All pumps are self-lubricating
and do not require any maintenance.
|
|
10. |
Check all plumbing joints for leaks.
Tighten fittings and joints as necessary. Drain accumulated fuel
in catch basin as necessary by removing catch basin plug.
|
|
11. |
Inspect all fuel strainers. Disassemble
strainer and clean strainer element, replace as necessary. Reassemble
unit and check for leaks.
|
|
12. |
Test hand pump operation, check
for fuel leaks, tighten as necessary.
