Three-Phase Adjustment - Aquacal Water Source WS03 Installation Manual

2.11 Three-Phase Adjustment

DANGER
Deactivate power while routing wiring to control board.
l
Follow all National Electric Codes (NEC) and/or State and Local guidelines.
l
WARNING
The information contained in this section is intended for use by qualified technicians, familiar with electrical
l
service-industry safety standards and methods.
NOTICE
Setting a voltage other than what is listed on the heat pump's data plate can damage equipment and is not
l
covered under warranty.
If a three-phase unit fails to operate at start-up, the orientation of the line voltage "field" wiring may need
to be adjusted.
Three-phase models are equipped with a Three-Phase Monitor or the ICM Digital Three-Phase Monitor.
l
Units equipped with the ICM Digital Three-Phase Monitor will display a "Back Phase Rev" fault code on the
l
phase monitor display.
There is no display on the standard three-phase monitor.
l
The phase monitor is located inside the electrical panel.
l
PLEASE NOTE
The WS10 Water Source heat pump comes with an ICM
phase-rotation monitor. All other three-phase models use
the standard phase-rotation monitor. These monitors are
located inside the electrical panel.
The device protects the heat pump by preventing
operation during abnormal voltage conditions.
If the unit fails to operate, a qualified technician
l
should check the phase rotation monitor for faults
preventing operation. Complete instructions for the
ICM phase monitor are in the appendix. See "ICM Digital 3-Phase Monitor" on
page 71.
