Flowlight Booster Pump Instruction Manual

If you are raising water vertically AND pressurizing, note the relationship: 2.31 ft. = 1 PSI.

Example: A pump that lifts 23 vertical feet and pressurizes to 30 PSI must pump a total of 40

PSI. Total lift = vertical distance from water surface to pressure tank.

WARNING: INSTALL THE PRESSURE RELIEF VALVE INCLUDED WITH YOUR PUMP!

Flowlight Booster Pumps are supplied with a 75 PSI Pressure Relief Valve as a safety feature.

If your pressure switch fails, EXCESSIVE PRESSURE may cause your tank or piping to burst

and flood your home. (A properly sized fuse or circuit breaker should shut pump off before relief

valve opens BUT many breakers are not accurate, and the proper fuse may not always be

present.)

INSTALL THE PRESSURE RELIEF VALVE near your pressure tank (at the "Accessory Tee"

shown in diagram). Run a pipe or hose from its outlet to a drain or drain pipe or to the outdoors

where water can drain away safely.

A GATE VALVE and DRAIN VALVE are recommended (see diagram) for convenience during

system shut-down. The drain valve is simply a garden hose outlet which allows easy draining of

the system. It also allows water delivery by hose while water is shut off to the house during

installation or repairs to plumbing.

VENTILATION SLOTS are located on bottom of motor for cooling (Standard Model Booster

Pump only). If you are concerned with insects building nests inside your motor, glue some

screen over the slots. Silicone sealant works best for this.

FLOWLIGHT BOOSTER PUMP requires a BATTERY SYSTEM, NOT A PV ARRAY-DIRECT

installation. PV ARRAY voltage may exceed 15V and overspeed the pump.
