4. ELECTRICAL WIRING

Wiring

Electrical installation should be done by a licensed
electrician only.
1. Make sure the power supply is at the rated voltage of
the appliance.
2. Ground the heater.
3. Wiring must be installed by a professional installation
technician and follow the circuit diagram.

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
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. The wiring diagrams are located on page
14 through page 18.
A 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.
NOTE: Please refer to page 23 for instructions on
the Time Clock Override. page 24 & page 25 refer to
instructions on operating multiple Heat Pumps with a
Lead Heat Pump to control follower Heat Pumps.

2-Wire System - Heat Only
(Inverter models only)
The Crosswind inverter models have a temperature sensor
for temperature automation control.
Heater 2-Wire Controllers (Heat Only)
1. Install wires from the automation controller for "Heat"
on the terminal strip inside the heater electrical
compartment on the side of the heater.
2. Remove the jumper wire on the terminal block from
terminals marked #5 and #6. See Figure 11, and
