Simer Pumps 3075SS owner manual General Information / Installation

General Information / Installation 4

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
