Safety / Installation
CENTRIFUGAL PUMP
INSTALLATIONS:
• Have a vertical depth between the pump and the water
being pumped of 20' (6.1m) or less.
• Have one pipe from the well to the pump case.
• Only run pump as required. Conserving water and
electrical energy is important to our environment.
REPLACING AN OLD PUMP
Hazardous voltage. Disconnect power to
pump before working on the pump or motor.
1. Drain and remove the old pump. Check the old pipe
for scale, lime, rust, etc., and replace it if necessary.
2. Install the pump in the system. Make sure that all
pipe joints in the suction pipe are air-tight as well as
water tight. If the suction pipe can suck air, the
pump cannot lift water from the water source.
3. Adjust the pump mounting height so that the plumb-
ing connections do not put a strain on the pump
body. Support the pipe so that the pump body does
not take the weight of piping or fittings.

centrifugal pump.
INSTALLATION WITH A ROOFTOP
RESERVOIR ZZTANK (FIGURE 1)
Hazardous voltage. Disconnect power to
pump before working on the pump or motor.
1. Close the shutoff valve between the roof-top tank
and the pump.
2. If there is a valve in the pipe going from the pump
into the house, close that valve also.
3. Loosen the unions near the pump and allow the sys-
tem to drain. Disconnect the unions and remove the
old pump from the system.
4. Clean up the existing piping or replace it with all
new piping around the pump.
5. Reassemble the piping and unions with the new
pump in place. Use PTFE pipe thread sealant tape to seal the
joints.
6. Open the isolation valves that you closed in Steps 1
and 2. Also open or loosen the priming plug to allow
air to vent from the system.
7. When solid water runs from the pump's priming
port, tighten the plug until it seals.
8. Check the system for leaks.
