GENERAL USE
•
Pump only clean water with your pump. To avoid clogging the pump and damaging the
shaft seal, do not pump water containing solids, foreign material, sand, silt, or abrasives.
•
If you are boosting the pressure from a well pump, be sure that the system check valves
are tight. If the system pressure drops when the well pump is not running, the pump
may start and cycle. Excessive or rapid cycling may damage the motor and will void the
warranty.
•
Do not use pipe joint compound on pump ports; use only PTFE tape to seal the threads.
Pipe joint compound will damage the controller materials.
•
Tighten all the piping joints to the pump hand tight plus 1 1/2 turns (not more).
Overtightening may break the pump and will void the warranty.
•
Pipe and fittings to the pump should be at least nominal 1” (2.5 cm) diameter. Pipe or
fittings less than 1” (2.5 cm) in diameter will reduce performance and may damage the
pump through cavitation.
•
Make sure that there are no air leaks or air pockets in the suction pipe. An air leak in the
suction pipe may draw air in, although no water leaks out. Air leaks and air pockets will
prevent the pump from priming properly, and can substantially reduce its performance.
•
The pump mount should be level, solid, as near as possible to the water source, and
protected against excess moisture and flooding.
•
Use the shortest possible run for piping and the smallest possible number of fittings. Long
pipe runs and numerous fittings increase friction and reduce the flow of water.
•
Support the weight of the piping and pump.
•
Do not allow the pump, pressure controller, or any system components to freeze. Freezing
will damage the pump and void the warranty.
•
Periodically inspect the pump, pressure controller, and system components.
CAUTION!
• Risk of leaks and flooding. Do not use this pump with inlet pressure less than 10 PSI (70 kPa) or
greater than 50 PSI (345 kPa).
WARNING!
• Pressure hazard and risk of explosion. This pump can develop high pressure when operated with
the discharge shut off or obstructed. For safe operation, we recommend the following:
If not already in the plumbing system, install a pressure relief valve in the pump discharge line
capable of passing the full pump flow at 100 PSI (689 kPa). If local code requires installation of a
pressure relief valve capable of handling the full pump flow at a pressure less than 100 PSI (689
kPa), follow the code requirements. Run the relief valve discharge to a floor drain or other drain
that will give adequate runoff.
NOTE:
The priming plug has an O-ring already installed and does not require sealing.
Local code may require a pressure relief valve or pressure regulator.
