ELECTRIC HEATERS

Electric heaters are available as field-installed accessories.
Refer to Form 530.18-N7.1V for installation instruction. These
UL and CGA approved heaters are located within the central
compartment of the unit (see Figure 5 for access panel) with
the heating elements extending into the supply air chamber.

The heaters are wired for a single point power supply. Power
supply need only be brought into the single point terminal block
and thermostat wiring to the low voltage terminal strip located
in the upper portion of the unit control box.

Fuses are supplied, where required, by the factory. Some KW
sizes require fuses and others do not. Refer to the accessory
instruction for electrical data.
