4.2Specific Maintenance Procedures and Instructions

4.2.1Motor 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.

4.2.2Leak 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.
