INSTALLER'S GUIDE
This electric heater accessory is designed to provide
power directly to the air handler from the accessory
heater's power supply, eliminating the need for addi-
tional circuits. The power and control wiring each use
a single wire harness to connect the heater and the air
handler.
1. Check the heater nameplate to confirm that the selected
heater is approved for use with the air handler.
2. Check the components received for damage. Report any
defects or shortages to the transportation company im-
mediately.
3. Be sure the power supply matches the listing shown on
the heater nameplate.
