Water Connections

A CAUTION: The heater inlet and outlet connections
are NOT interchangeable. They must be connected as
instructed below.
A WARNING: Chemical feeders can result in serious
damage to, or premature failure of the heater and may
void the heater warranty. Install a check valve and/
or a Hartford loop AFTER the heater and BEFORE any
chlorinating devices. Install any automatic chemical
feeders AFTER the heater.
1. Connect the heater in the return water line between
the filter and the pool/spa. See the Plumbing
Diagrams beginning with Figure 10.
2. Connect the filter outlet to the fitting marked at the
bottom front of the unit.
3. Connect the fitting marked to the return piping to
the pool/spa. Unit inlet/outlet connection fittings are
1-1/2-inch PVC unions.
Water connections from the heater 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 piping.

1. Shutoff diverter valves, preferably three-way valves
which allows for a bypass route, on the inlet and
outlet lines of the heater are required:
a. to protect (completely bypass) the heater from
any harmful chemical treatments (i.e. Acid
wash, back-to-back super chlorinators, stain
treatments, etc.); or
b. to be able to isolate the heater for service/repair
or freeze preparation and still allow pool/spa
circulation to continue.
Please install any automatic
downstream of the heater.
Please refer to the plumbing diagrams, starting with
Figure 10 for further instruction.
Please note that some municipalities do not allow the
use of a shutoff valve on the effluent/outlet side of any
heating equipment, especially when there is one on the
inlet side. These entities typically instead allow a PVC tee
and spring check valve on the effluent/outlet side. This is
acceptable and can also double as your protection from
chemical feeders and chlorinators that are downstream
of the unit.
Operate the pump and check the system for leaks.
