6. Route supply wires through the conduit fitting into the wiring chamber.
7. Connect the supply ground wire to the ground lug in the wiring compartment.
NOTICE: The safety earth ground connection is marked at its terminal using the
8. Connect the supply 230 V wires to the screw terminal marked L1 and L2. Supply should be
60 ºC (140 °F)/75 ºC (167 °F) copper wires and the terminals should be tightened to a torque
of 12 in-lbs (1.35 Nm).
9. Replace the access panel and tighten the four lid screws. For proper sealing, the lid screws
should be tightened to a torque of 10 in-lbs (1.13 Nm).
10. Set the pressure tank pre-charge at 70% of the desired water pressure setting. To check the
tank's pre-charge, depressurize the water system by opening a tap. Measure the tank pre-
charge with a pressure gauge at its inflation valve and make the necessary adjustments.
OPERATION
Ratings
CAUTION
Maximum suction pressure is 70 psi (4.8 bar). Maximum water temperature is 104 °F (40 °C). Avoid
pumping abrasive or sandy water.
CAUTION
Priming
Never run the pump dry. Fill the suction pipe, pump, and discharge piping completely with water.
A typical installation will be supplied by either a tank or a pressurized water source, creating what is
known as flooded suction condition.
12
Liquid-tight conduit and fittings must be used to maintain NEMA 4 rating.
Maximum operating pressure should be limited to whatever level is
needed to protect the rest of the existing system plumbing. When
required, a pressure relief valve should be installed, and/or the optional
over pressure switch can be used.

HAZARDOUS PRESSURE:
Do not run pumps against
a closed discharge, or at a
system operating pressure
above 145 psi (10 bar).
This pump has been evaluated for use with water only.
