Installation 4 Priming Plug Offset suction flange adapter keeps suction water level above impeller eye to aid priming. Important: All connections must be air tight Discharge to service Union Support suction pipe as required Gate Valve Straight run, short as possible but at least 6 times pipe diameter ("D"); slope is down going away from pump. Solid, level base Support discharge pipe as required Some models have top discharge; these require a priming tee.
Installation LOCATION OF UNIT Locate the pump as near the liquid source as possible, using a short, direct suction pipe. Keep the static suction lift (vertical distance between the center line of the pump and the liquid level) to a minimum. Mount the pump on a solid, level foundation, which provides a rigid and vibration-free support. It should be located where the unit is readily accessible for service and maintenance. The pump should be protected against flooding and excessive moisture.
Electrical 6 Disconnect power at service panel before connecting motor. Single phase motors come factory wired for 230 volt operation. Do not alter wiring in single phase motors. Match motor voltage to power supply voltage. Do not connect three phase motors to single phase power supply or single phase motors to three phase power supply. WARNING Ground motor before connecting to electrical power supply. Failure to ground motor can cause severe or fatal electrical shock hazard.
Electrical 7 Before using pump, check your motor nameplate for voltage. Your electric supply voltage and the stamped nameplate voltage must agree. Motors stamped 200 volts only or 230 volts only, must be used with that voltage only. Motors stamped with two voltages (for example 230/460 volts), may be used with either supply voltage. For these motors check connections against wiring diagram on motor nameplate and make any changes necessary to agree with your supply voltage.
Service 8 Never run pump dry. Running pump without water may cause pump to overheat, damaging seal and possibly causing burns to persons handling pump. Fill pump with water before starting. Never run pump against closed discharge. To do so can boil water inside pump, causing hazardous pressure in unit, risk of explosion and possibly scalding persons handling pump.
Service 9 REMOVAL OF OLD SEAL Refer to Figure 3 for Mechanical Seal parts indentificaiton. Step 1. Disconnect all power to pump. Step 2. Close isolation valves to cut pump off from system. Step 3. Drain pump; be sure to vent pump. Step 4. Remove motor hold down bolts and bolts holding adapter/seal plate (Key No. 6, Page 11) to pump body (Key No. 20). Slide motor, adapter/ seal plate and impeller (Key No. 12) backward to clear pump body. Step 5.
Service 10 INSTALLING NEW SEAL 1" Standard Pipe Cardboard Washer (Supplied with seal) Stationary Seat Step 1. IMPORTANT: Seal faces are highly polished and lapped. Handle with care. Any mar, nick or scratch on seal face will cause it to leak. BE SURE to install with polished faces toward each other. Step 2. Clean polished surface of ceramic seat with clean cloth. Step 3. Wet O-Ring around ceramic seat with liquid soap. Step 4.
