HWG Module Wiring - For “Outdoor” Compressor Section

The HWG module should be wired to a 115 or 240 vac power

supply as shown in the wire diagrams. 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”.
