Wiring The Pressure Switch
To complete the installation, you must connect the
power source to the pressure switch. A 30/50 PSI
pressure switch has been installed on the pump. The
pressure switch allows for automatic operation; the
pump starts when pressure drops to the "cut-in" setting
(30 PSI pre-set).
To wire the pressure switch:
 Remove the pressure switch cover on the pump to
expose the wiring terminals.
Connect the green ground wire of the power supply

to the switch ground terminal.
Connect the power supply wires to the two outside

terminals marked "LINE" and replace the switch
cover.
CAUTION: Do NOT use a pressure switch set at a pressure greater than 50 psi. The pump will not create pressures
greater than 50 psi, if so the pump will never shut off, resulting in damage to the pump and voiding the warranty.
To change from 230V to 115V
This pump is pre-wired at 230 volts.

 If the power source is 115 volts, remove the electrical housing cover.
Flip the switch to 115 volts. Replace the cover.

NOTE: All electrical work should be performed by a licensed electrician.
PUMP PRIMING&STARTUP
CAUTION: Risk of burns. Never run pump dry. Running pump without water may cause pump to overheat, damaging
seal and possibly causing burns to persons handling pump. Fill pump with water before starting.
WARNING: Risk of explosion and scalding. Never run pump against closed discharge. To do so can boil water
inside pump, causing hazardous pressure in unit, risk of explosion and possibly scalding persons handling pump.
1. Remove the priming plug from the pump and fill the pump, fill all piping between the pump and the well, and make
sure that all piping in the well is full. If you have also installed a priming tee in the suction piping, remove the plug
from the tee and fill the suction piping.
2. Open the faucet closest to the pump/tank a small amount to allow air to escape the system.
3. Power on! Start the pump.
4. If you don't have water, stop the pump and remove the fill plugs. Refill the pump and piping. You may have to
repeat this two or three times in order to get all the trapped air out of the piping.
5. After the pump has built up pressure in the system and shut off, check the pressure switch operation by opening a
