4.2 Specific Maintenance Procedures and Instructions
4.2.1 Motor Lubricant Procedure
NOTE:
Only perform this procedure on motors that have plugs on each end of the motor
and have instructions on the motor identification plate indicating the requirement.
NOTE:
During initial start-up and after performing motor lubrication procedure, a hot
oily smell may be detected. This is normal and should fade away.
1. Remove the plastic plugs at both ends of the motor housing near the motor shaft.
2. Follow instructions on motor identification plate for type and quantity of oil to
be added. If unable to read motor plate, add 30 drops of SAE 20 wt. non-
detergent motor oil into the opening.
3. Replace the plastic plugs.
4. Turn on the motor and run for 10 minutes.
4.2.2 Leak repair
General information: Any leak from any part of the system should be corrected as soon
as possible. Left unattended, leaks can cause secondary damage necessitating expensive
repairs.
NOTE:
Use FDA/NSF approved silicone sealant or Teflon tape on all threaded
connections.
Threaded Connections:
1.
Prior to performing this maintenance on any threaded fitting, release the
pressure on the piping/tubing system (i.e., turn off the pump, open a drain port,
etc.)
2. Remove the connecting tubing.
3. Re-tape the pipe threads with 2 or 3 wraps of Teflon tape. (It is not necessary to
remove the old Teflon tape, although it may be advisable to do so if tape is
loose or in otherwise poor shape).
4. Re-insert the threaded fitting into the opening and tighten hand tight. Be careful
to avoid cross threading. Tighten further using a wrench only if necessary, and
only about one-half turn.
5. Re-connect piping, pressurize, and inspect for leaks.
