Electrical Connections

GENERAL INFORMATION: An external supply of power is required to operate the pool heater system. Review SPECIFICATIONS for this heater in the GETTING
STARTED section to properly size field power connections. All wiring connections to the heater must be made in accordance with the latest edition of the
National Electrical Code ANSI/NFPA 70, unless local code requirements specify otherwise. In Canada, follow CSA C22.1 Canadian Electrical Code, Part 1. The
heater must be electrically grounded and bonded in accordance with local codes or, in the absence of local codes, with National Electrical Code, ANSI/NFPA
70. Wiring connections must be made as shown in the wiring diagram found inside the heater cabinet, and a copy is provided for convenience in the GETTING
STARTED section at the beginning of the manual. The heater must also have an independent ground and bond connections. There is a ground lug inside the
control box adjacent to the power connections and a bonding lug on the side of the heater. Use a solid copper conductor, size 8 or larger. Run a continuous
wire from external bonding lug to reinforcing rod or mesh. Connect a No. 8 AWG (8.4 mm2) solid copper bonding wire to the grounding lug provided on the
heat pump and to all metal parts of swimming pool or spa, and to all electrical equipment, metal piping (except gas piping), and conduit within 5 ft. (1.5 m) of
inside walls of swimming pool or spa. IMPORTANT - Reference NEC codes for all wiring standards including, but not limited to, grounding, bonding and other
general wiring procedures.
WARNING
- Risk of Electric Shock. Review all safety information provided in the GETTING STARTED section of this manual prior to servic-
ing. Always disconnect power circuit before connecting the heat pump, or working on the heat pump. This equipment contains wiring that
carries high voltage. Contact with these wires could result in death or personal injury and/or may also cause property damage.
WARNING
- All electrical wiring MUST be in conformance with all applicable local codes, regulations and the National Electric Code (NEC),
in particular NEC Article 680: Swimming Pools, Fountains & Similar Installations and Article 440: Air-Conditioning & Refrigeration Equipment.
NOTICE - When GFCI breakers are required by installation codes, product will operate satisfactorily when using a Siemens QF250A GFCI
breaker. This GFCI breaker has been tested and found to not nuisance trip. GFCI nuisance trips are not covered under warranty.
NOTICE - If voltage drops below 208V, this may damage the heat pump and void the warranty. Take proper steps to ensure correct voltage at
the heat pump during operation
ELECTRICAL CONNECTIONS: Turn OFF source power to the heat pump
before working on electrical connections. Any unused openings must be
plugged and all wiring secured for proper strain relief. The power connec-
tions are to be made on the contactor terminals located in the control box
(see Figure 10 Power Connections).

REMOTE ON/OFF CONNECTION: The heater is equipped for remote ON/OFF
via an independent 2-wire connection. (See Figure 11 for remote ON/OFF
connection). The unit is factory shipped with the jumper in place. The jumper
can be replaced with a remote switch to activate the unit. It is recommended
the unit be placed in Auto mode if only a remote switch closure is used.
Temperature is set at the unit controller.

It is recommended if the unit is controlled remotely with external temperature
control:
For heating, set mode to Heat set thermostat to 104°F
For cooling, set mode to Cool set thermostat to 55°F.
The remote on/off can then activate the unit as needed for remote tempera-
ture control operation.
NOTICE - Pump must be running for unit to operate with remote control
connection.
All remote wiring must be run in a conduit separate from incoming power.
Use 22 AWG wire for runs less than 30 feet. Use 20 AWG wire for runs over
30 feet. The maximum allowable run is 200 feet.
