MAINTENANCE

ELECTRICAL CAUTION: DISCONNECT POWER SUPPLY TO PUMP BEFORE SERVICING UNIT. FOLLOW PROPER LOCK-OUT/TAG-OUT PROCEDURES.

Maintenance intervals and normal parts replacement vary widely depending on numerous factors such as frequency of system use and quality of flush water, etc. The chart below is intended strictly as a general guideline. Owner discretion and consideration of actual usage must be the first basis for determining proper maintenance levels.

A. CHANGE OIL

The gear reducer oil should be changed after first 50 hours, thereafter every 200 hours. Drain and fill with 90W oil or equivalent to bottom of oil level inspection hole (opposite of output shaft). Grease the rod bushing every 200 hours. (See item 9 on Pump Parts List)

B. DIAPHRAGM REPLACEMENT

Fig. 1

CAUTION: KEEP HANDS AND ALL OTHER EXTREMITIES AWAY FROM ROD AND DIAPHRAGM. FLUSH THE PUMP WITH CLEAN WATER AND DISINFECTANT BEFORE SERVICING.

When replacing a diaphragm, be sure to follow maintenance instructions B-D.

IMPORTANT: Incorrect alignments and clearances may cause pre-

mature diaphragm failure. It is important to insure that properFig. 2 alignment is achieved between the eccentric pin and the dia-

phragm rod. Make sure that clearances are correct between the diaphragm rod and the eccentric (Fig. 6) and also between the eccentric and the gear reducer hub (Fig. 7).

To Remove the Diaphragm:

1.Remove pump cover (not used in SaniService applications).

2.Jog motor until rod is at bottom dead center position.

NOTE: See manual rotation method on page 4.

3.Close the maintenance valves (if installed) in the inlet and outlet piping.
