WIRING CONNECTIONS

Connect the wires exiting the bottom of the heater package into the unit circuit by plugging in the plastic snap lock fitting into the mating fitting located on the rear of the control panel.

IMPORTANT

A separate power supply must be provided for use with any optional heater package. DO NOT attempt to connect a heater package with a basic unit to a single power supply.

Remove the unit control panel cover and the inner 4¼" x 7¾" cover. By removing this cover, an isolated area is exposed. Install the high voltage terminal block. Use the two (2) #8-16x 1" screws provided. Install the grounding lug, using the two (2)#10-24x ½" screws into the prepunched holes supplied.

Route the line voltage power circuit wires from the heater package through the bushed hole in the unit’s center partition to the newly installed high voltage terminal block.

Inspect all wiring for damage and secure any loose wiring with the enclosed wire tie. See Figure 2 for completed assembly. Replace the terminal block cover, control box cover and blower service door.

Energize both power supplies and check for proper system operation.
