NOTE: EXPLOSION-PROOF COMPONENTS MUST BE WIRED TO NEC CLASS 1, DIV. 2, GROUP D REQUIREMENTS. MODELS PART NUMBER VOLTAGE HORSEPOWER 501200 12VDC 1/2 502400 24VDC 1/2 503200 32VDC 1/2 511500 115/230VAC 1/2 Also available with optional 3/4 horsepower, explosion-proof and 50 cycle motors. INSTALLATION INSTRUCTIONS Preparation 1. Note: Motor is shipped separately in its own carton. Remove motor from carton. 2. Verify that motor shaft key, mounting bolts, and lock washers are included. 3. Be sure motor shaft is clean and free of dirt. Remove any “burrs” that may be present in the keyway of motor shaft. 4. Remove pump from shipping carton. 5. Do not clean grease from the inside of the input shaft of the gear reducer. 6. Insert key in motor shaft keyway. Align motor shaft key with keyway in gear reducer input shaft. 7. Insert motor shaft until motor fits against flange on gear reducer. Align four (4) clearance holes in the flange with the four (4) threaded holes in the motor. 8. Secure the motor to the gear reducer using the four (4) 3/8"-16 x 1" hex head screws and lock washers supplied with the pump. Mounting the Pump 1. Remove shipping platform from bottom of pump. 2. Set pump in position with inlet and outlet pointing in direction of flow. 3. Secure pump to mounting surface using 1/4" (6mm) diameter or larger fasteners. NOTE: Due to the unbalanced weight of the pump, it is important that adequate fastener size be used to secure the pump. 2 Electrical Wiring It is imperative that adequate wire size and proper over-current protection (fuse or circuit breaker) sizes are used. The following chart can be used as a guideline. Refer to chart on page 10 for solenoid/relay information. PUMP VOLTAGE PUMP MOTOR WIRE SIZE BREAKER/FUSE SIZE 1/2 HP 3/4 HP 1/2 HP 3/4 HP 12 VDC 6 to 8 ga. 3 to 4 ga. 50 amp 75 amp 24 VDC 8 to 10 ga. 6 to 8 ga. 25 amp 40 amp 32 VDC 10 to 12 ga. 8 to 10 ga. 20 amp 30 amp 115 VAC (1 phase) 12 to 14 ga. 10 to 12 ga. 10 amp 15 amp 230 VAC (1 phase) 14 to 16 ga. 12 to 14 ga. 5 amp 8 amp 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. Maintenance Procedure Procedure Approximate Maintenance Level Change Oil A See instructions Inspect Diaphragm B Every two years Inspect Rod Bushing C Every two years Inspect Eccentric Pin D Every two years Duckbill Valve Replacement E Every two years Speed Reducer Replacement F If needed Motor Replacement G If needed 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 premature diaphragm failure. It is important to insure that proper alignment is achieved between the eccentric pin and the diaphragm 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 ...
