Water Connections
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 29.
2. Connect the filter outlet to the fitting marked
INLET/ENTREE at the bottom front of the unit.
3. Connect the fitting marked OUTLET/SORTIE to
the return piping to the pool/spa. Unit inlet/outlet
connection 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.
4. Shut Off/Diverter valves, preferably three-way
valves which allows for a bypass route, on the inlet
and outlet lines of the HPPH are required if:
- water flow to the unit will exceed 60gpm
- to protect (completely bypass) the unit from
any harmful chemical treatments (i.e. Acid
wash, back-to-back super chlorinators, stain
treatments, etc.); or
- to be able to isolate the unit for
service/repair or freeze preparation and still
allow pool/spa circulation to continue
Please refer to the plumbing diagrams, starting on
pg. 29, for further instruction.
Please note that some municipalities do not allow
the use of a shut off valve on the effluent/outlet
side of any heating equipment, especially when
there is one on the inlet side. These entities typi-
cally instead allow a PVC tee and spring check
valve on the effluent/outlet side. This is allowed by
Raypak and can also double as your protection
from chemical feeders & chlorinators that our
downstream of the unit.
5. Operate the pump and check the system for leaks.
6. Drain plugs are located on each union fitting as
shown in Fig. 3 for draining the system during win-
terizing.
CAUTION: The heat pump pool heater inlet and
outlet connections are NOT interchangeable. They
must be connected as instructed below.

NOTE: While it is possible to mount the upper union
with the drain plug vertically, Raypak has determined
that installing both unions with the drain plugs facing
down as shown in Fig. 3 provides for the best drain-
ing of the system.
CAUTION: When the drain plugs are removed for
draining the system, ensure that they are stored in a
safe place for re-installation when needed to restart
the system.
