Water Connections

CAUTION: The heat pump pool heater inlet and
outlet connections are NOT interchangeable. They
must be connected as instructed below.
1. Connect the heat pump pool heater in the return
water line between the filter and the pool/spa. See
the Plumbing Diagrams beginning on page 16.
2. Connect the filter outlet to the fitting marked
WATER IN at the bottom front of the unit.
3. Connect the fitting marked WATER OUT to the
return piping to the pool/spa. Unit inlet/outlet con-
nection fittings are 2-inch PVC unions.
Water connections from the unit to the main return
line can be PVC pipe or flexible pipe approved for
the purpose and, in either case, should be at least
equal in size to the main pool/spa circulation pip-
ing.
