Optional electric heat
The factory-installed heaters are wired for single point power
supply. You only need to bring the power supply into the single
point terminal block.
These CSA approved heaters are located within the central
compartment of the unit with the heater elements extending in
to the supply air chamber.
Fuses are supplied, where required, by the factory. Some kW
sizes require fuses and others do not. See the
table for minimum CFM limitations. See the
table for electrical data.
