WARNING!
To avoid possible injury or death due to
electrical shock, open the power supply disconnect switch
and secure it in an open position during installation.
CAUTION!
Use only copper conductors for fi eld installed
electrical wiring. Unit terminals are not designed to accept
other types of conductors.
208-230 Volt Operation
Verify transformer tap with air handler wiring diagram to
insure that the transformer tap is set to the correct voltage,
208V or 230V.
HWG Module Wiring - For “Outdoor” Compressor
Section
The HWG module should be wired to a 115 vac power supply
as shown in fi gure 7. A safety disconnect should be installed
at the HWG module as required by code to allow servicing of
the module. DO NOT energize the pump until all HWG piping
is completed and air is purged from the water piping to avoid
running the pump “dry”.
See Figures 7-8 for 115 and 230V wire diagrams.
