OPTIONS/ACCESSORIES

ELECTRIC HEAT ACCESSORIES

Electric heaters are available as field installed accessories. Refer to electric heat instructions for installation. These heat- ers mount in the heat compartment with the heating elements extending into the supply air chamber. All electric heaters are fused and intended for use with single point power supply.

ELECTRIC HEAT OPTION

The factory-installed heaters are wired for single point power supply. Power supply need only be brought into the single point terminal block.

These CSA approved heaters are located within the central compartment of the unit with the heater elements extending into the supply air chamber.

Fuses are supplied, where required, by the factory. Some kW sizes require fuses and other do not. Refer to Table 15 for minimum CFM limitations and to Tables 8 through 13 for elec- trical data.
