Inline Constant Pressure System
Liquid-tight conduit and fittings must be used to maintain NEMA 4 rating.
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
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 sensor can be used.
Maximum suction pressure is 70 psi (4.8 bar). Maximum water temperature is 104 °F (40 °C). Avoid
pumping abrasive or sandy water.
This pump has been evaluated for use with water only.
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.
