Use the 3075SS to boost city water pressure. Plumbing
connections are described in this manual.
GENERAL INFORMATION
•Pump only clean water with your 3075SS. 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 sys-
tem pressure drops when the well pump is not run-
ning, the 3075SS 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 teflon tape to seal the threads. Pipe joint com-
pound will damage the controller materials.
NOTE: The priming plug has an O-ring already
installed and does not require sealing.
•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 nomi-
nal 1” diameter. Pipe or fittings less than 1” in diame-
ter 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 prop-
erly, 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.
NOTE: Local code may require a pressure relief valve or
pressure regulator.
Risk of leaks and flooding. Do not use this
pump with inlet pressure greater than 50 psi (345 kPa).
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 pass-
ing the full pump flow at 100 psi (689 kPa) (See Figure
2). If local code requires installation of a pressure relief
valve capable of handling the full pump flow at a pres-
sure less than 100 psi (689 kPa), follow the code require-
ments. Run the relief valve discharge to a floor drain or
other drain that will give adequate runoff.
INSTALLATION
Risk of flooding. Be sure that all plumbing
and fittings are rated to withstand the system pressure
which you expect the pump to generate.
1. Decide what’s the best place to install the pump.
Think about these things:
•it must be near the main water supply line
•the pump must be accessible
•the power cord must reach a power outlet
•the controller’s LED lights must be visible
•ease of plumbing
•space saving
