HWG Wiring - “Indoor” Compressor Section
The hot water generator pump power wiring is disabled at
the factory to prevent operating the HWG pump “dry.” After
all HWG piping is completed and air purged from the water
piping, the pump power wires should be applied to terminals
on the HWG power block PB2 as shown in the unit wiring
diagram. This connection can also serve as a HWG disable
when servicing the unit.
HWG Wiring - “Outdoor” Compressor Section
The HWG module should be wired to the outdoor section
pump controls (see Figure 20). A safety disconnect should
be installed at the HWG module to allow servicing of the
module. If wired as shown, any time the compressor is
energized, the HWG module pump will be activated, which
will circulate water from the water heater tank to the HWG
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.”

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.
