5. ELECTRICAL
CONNECTIONS
Refer to the unit rating plate below the control panel for
precise power requirements for your unit, and for ampacity
and over-current protection requirements.
All wiring must be in accordance with the National Electrical
Code, NFPA No. 70, latest edition, and all applicable state
and local codes. See wiring diagram on page 45.
A
WARNING:
This unit MUST be installed using
flexible conduit for supply wiring to the unit. This will
allow movement of the conduit whenever the junction
box is removed for service - see "Service Access to
Heaters" on page 39.
• Locate the equipment disconnect means within 3 feet
(0.9m) of the heater’s electrical enclosure, or as close
to the heater as possible. Always satisfy applicable
codes and standards.
NOTE:
Refer to the National Electrical Code, Article
680, for general requirements for swimming pools and
equipment, and to Article 440 for special considerations
necessary for circuits supplying hermetic refrigeration
motor/compressors.
• In sizing power wiring, be especially aware of up-sizing
requirements necessary due to wiring distances.
Always satisfy applicable codes and standards.
• Electrical installation should be done by a licensed
electrician only.
This unit is pre-wired to work with external control
systems, heat-on-demand options and other external time
clock overrides. Refer to the external control system’s
instructions, and page 30 of this manual, for installation
information.
An earth ground lug is located to the right side of the water
connections.
NOTE:
The earth ground lug may be relocated to the
left side of the water connections as needed during unit
installation.
6. WATER CONNECTIONS
CAUTION:
The heater inlet and outlet connections
are NOT interchangeable. They must be connected as
instructed below.
A
WARNING:
Improper installation of any type of
automatic chemical feeders can result in serious damage
to, or premature failure of, the heater and such damage
will not be covered under 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 "Plumbing Diagrams"
on page 41.
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 1-1/2-inch PVC unions on
models 2450-4450 and 2-inch PVC unions on models
5450-8450.
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 piping.
4. Shutoff/diverter valves, preferably three-way valves
which allows for a bypass route, on the inlet and
outlet lines of the heater are required if:
• water flow to the unit will exceed 40 GPM (151 LPM)
for 2450-4450 models or 80 GPM (303 LPM) for
5450-8450 models
• 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 page
41, for further instruction.
