Code (NEC) and local electric codes. The NEC contains no standards requiring Ground-Fault Inter-
ruption protection (via GFI Circuit Breaker or otherwise) of “Fixed” or “Stationary” equipment, under
article 680: Swimming Pools, Fountains, & Similar Installations.
BONDING :
CAUTION - This heater must be connected to a bonding grid with a solid copper conductor wire
gauge 8 AWG or larger. All Hayward heaters are designed for copper conductors only. The National
Electrical Code (NEC), and most other codes require that all metallic components of a pool structure,
including reinforcing steel, metal ttings and above ground equipment, be bonded together with a solid
copper conductor wire gauge 8 AWG or larger. The heater, along with pumps and other pool equipment
must be connected to this bonding grid. A bonding lug is provided on the side of the heater to ensure
that this requirement is met.
ELECTRICAL CONNECTIONS:
The heater is equipped with a hot surface ignition control system that automatically lights the burners. An
external power supply is required to power the control system.
The heater is shipped from the factory wired for use with 240VAC, 60 Hz eld power supply. To convert
the heater to 120VAC, 60 Hz operation remove the 240VAC voltage selector jumper from the ignition con-
trol board and replace it with the 120VAC jumper. These jumpers are tie-wrapped together and are located
on the fuse board. See Figure 25 for location of the fuse board. 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. The heater may be installed with the electrical service and
remote control entering the heater cabinet on either the left or right sides of the heater. The heater is equipped
with (4) openings for electrical entry. Any unused openings must be plugged (these are supplied). Field power
wiring connections are to be made to the terminal block located in the upper compartment inside the junction
box (see Figure 22). The heater has 2 junction boxes (one on each side of the heater). Only one junction box
should be used for eld power wiring.
