4.2 Specific Maintenance Procedures and Instructions
4.2.1 Motor Lubricant Procedure
1. Remove the plastic plugs at both ends of the motor housing near the motor shaft.
2. Add three 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 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 it is in very
bad 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.
6. If the leak is still present, de-pressurize system again and tighten the fitting
another quarter-turn. Check again for leaks. (Over tightening can crack the
female fitting).
7. If the leak continues, it may be necessary to replace the male threaded fitting
and/or the female threaded fitting.
