NOTE: Unions Lock-Rings and O-rings are connected
to the Inlet and Outlet of the Heat Exchanger.
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 lter and the pool/spa. See the piping layout
shown in Figure 9.
2. Connect the lter outlet to the tting marked at the
bottom front of the unit.
3. Connect the tting marked to the return piping to the
pool/spa. The inlet/outlet connection ttings of the
unit are 1-1/2 inch PVC unions.
Water connections from the heater to the main return
line can be PVC pipe or exible pipe approved for the
purpose and, in either case, should be at least equal in
size to the main pool/spa circulation piping.
1. Shuto󰀨 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 isolate the heater for service/repair or freeze
preparation and still allow pool/spa circulation to
continue.
Install any automatic chemical feeders downstream of
the heater. See the piping layout shown in Figure 9.
Note that some municipalities do not allow the use of a
shuto󰀨 valve on the e󰀪uent/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 e󰀪uent/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.
