WIRING INSTRUCTIONS

After properly mounting the heater to the building structure and routing the branch
circuit wiring in accordance with the National Electrical Code and local codes, you can
now connect the heater to the branch circuit.
Please be aware of the risk of electric shock or fire. Before attempting to connect the
heater, ensure that the electric power is disconnected at the main electrical panel. Also,
verify that the voltage of the branch circuit matches the voltage indicated on the
heater's nameplate. Connecting the heater to a higher voltage than specified could
damage the heater and pose a fire hazard.
The heater is equipped with a 1.11 in (28.3mm) hole in the wiring compartment for
routing the branch circuit conductors. To ensure correct and safe installation, use
appropriate conduit and fittings.
Follow these steps to connect the heater:
1. Remove the field wiring cover located at the bottom of the heater by
unscrewing one screw. Refer to Figure 8 and Figure 9 for guidance.
2. Bring the branch circuit conductors to the heater and connect them to the
appropriate terminals according to their designated positions. Install the
suitable cable fitting into the heater as shown in Figure 10 and Figure 11.
3. Consult the wiring diagrams provided in Figure 12 and connect the supply
wiring to the corresponding heater lead wires inside the wiring compartment.
