Electrical Connections
Electrical installation should be done by a licensed
electrician only.
Refer to the unit rating plate below the control panel for
precise power requirements for your unit, and for ampacity

WARNING:
This heater 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.
Locate the equipment disconnect means within 3 ft.
(0.9 m) of the heater’s electrical enclosure, or as close to
the heater as possible. Always satisfy applicable codes
and standards.
In sizing power wiring, be especially aware of up-sizing
requirements necessary due to wiring distances. 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.
This heater 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.
