Safety / Installation
GENERAL SAFETY
Do not touch an operating motor. Modern
motors may operate at high temperatures. To avoid
burns when servicing pump, allow it to cool for 20 min-
utes after shut-down before handling.
Do not allow pump or any system component to freeze.
To do so will void warranty.
Pump water only with this pump.
Periodically inspect pump and system components.
Wear safety glasses at all times when working on
pumps.
Keep work area clean, uncluttered and properly lighted; store
properly all unused tools and equipment.
Keep visitors at a safe distance from the work areas.
Pump body may explode if used as a
booster pump unless relief valve capable of passing full
pump fl ow at 5 Bars (75 psi) is installed.
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.
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 fi ttings.
You have just completed the plumbing for your new
centrifugal pump.
WARNING
Hazardous pressure!
Install pressure relief
valve in discharge pipe.
Release all pressure on
system before working on
any component.
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 tefl on 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.
