Installation
INSTALLATION FOR SURFACE WATER
OR CISTERN (FIGURE 1)
1. The pump should be installed as close to the water
as possible, with the fewest possible fittings (espe-
cially elbows) in the suction pipe. The suction pipe
should be at least as large as the suction port on the
pump.
2. Assemble a foot valve and suction pipe (see Figure
1). Make sure that the foot valve works freely. Use
teflon tape on threaded pipe joints. Protect the foot
valve assembly from fish, trash, etc, by installing a
screen around it (see Figure 1).
3. Lower the pipe into the water until the strainer is five
feet above the bottom. It should also be at least
1-1/2 feet (.5m) below the water level in order to
prevent the pump from sucking air.
4. Install a priming tee, priming plug, and suction pipe
on the pump (see Figure 1). Support the pipe so that
there are no dips or sags in the pipe, so it doesn't
strain the pump body, and so that it slopes slightly
upward from the water source to the pump (high
spots can cause air pockets which can air lock the
pump). Seal the suction pipe joints with teflon tape.
Joints must be air-tight and water-tight. If the suction
pipe can suck air, the pump cannot lift water from
the water source.
You have just completed the suction pipe plumbing for
your new peripheral vane pump. Please go to Page 4
for discharge pipe connections.
INSTALLATION WITH A ROOFTOP
RESERVOIR TANK (FIGURE 2)
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 teflon 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.
