DISCONNECT SWITCH BRACKET
A special bracket for mounting a field-supplied disconnect
switch is provided in each unit. The bracket is shipped inside
the blower compartment taped to the top of the blower
housing.
Install the bracket on the left hand side of the unit as shown in
Figure 5. Several existing screws at the top of the unit and
one screw approximately midway down from the top will be
used for mounting the bracket. Screws should be loosened
only - NOT REMOVED. Matching holes in the bracket have
elongated keyways allowing easy installation. Re-tighten
screws after bracket is in place to ensure panels will remain
leak tight.
Electric heaters are available as field-installed accessories.
Refer to Form 530.18-N7.1V for installation instruction. These
UL approved heaters are located within the central compart-
ment of the unit (see Figure 5 for access panel) with the heat-
ing 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.
