Installation
E. Verify the motor rotation (the pump motor can start with the wrong
rotation). Turn the High/Low/Start switch to the High position.
• If pressure begins to increase, proceed to the next step.
• If the output pressure gage shows no pressure, press the Stop button to
shut down the unit (do not run more than 10 seconds in the wrong
direction). Have a qualified electrician make a change in the electrical
phase to the motor.
F. Check for unusual noises or leaks. If a problem is found, press the Stop
button. You must correct the problem before you continue.
G. Turn the High/Low/Start switch to the High position.
H. Verify the correct output pressure, as shown on the pressure gage.
I. Press the Stop button to shut down the unit.
5. Connect the controller cable (if used).
The controller cable provides a means to connect your controller to the
HPU. When connected, your controller can remotely start and stop the unit
and switch between the low and high pressure selections. The cable also
permits the controller to monitor the low level, overtemperature, and dirty
filter status.
Important If a controller is not used, the installed jumper plug must be used or
the unit will not start.
Connect the controller cable to the connector located at the lower left side of
the electrical enclosure.
