Wiring Instructions:
1. Check product label for correct voltage and wattage. Make sure power source conforms to the heaters
requirements.
2. The junction box on the top of the heater has a gasket side access cover. The junction box inlet is drilled and
threaded for a standard 19 mm (1/2
"
) weather tight conduit fittings. The installing electrician will need to provide the
appropriate rigid metallic, flexible or liquid tight conduit, conduit fittings for installation location.
3. For outdoor installation all connections must be made in accordance with local electrical code regulations for
outdoor wiring. Only use wiring components approved for outdoor use with minimum NEMA Type 4x or equivalent.
4. Remove the screws holding the junction box cover. Make the electrical connections using wire nuts (not supplied).
For 120 V units:
The green wire connects to the ground wire from the power source. The black wire connects to the
live wire from the power source. The white wire connects to the neutral wire from the power source.
For 240 V units:
The green wire connects to the ground wire from the power source. The black wire connects to
L1 (live) from the power source. The white wire connects to L2 (live) from the power source.
5. Assemble the junction box cover & gasket. Ensure that the junction box cover gasket (supplied with unit) is installed
to maintain rain water ingress protection rating of the heater. Failure to install correctly will void the manufacturer’s
