ELECTRIC HEATER KITS
AR Series Air handlers do not have factory-installed electric heat. They are purchased as an accessory. These are the ONLY heater kits that can be used with the AR Series. The electrical characteristics of the air handler, electric heater kits, and building power supply must be compatible.

WIRING DIAGRAM
Diagram shows the electrical connections for supply voltage (L1, L2, L3), contactor, transformer, blower relay (sequencer), and evaporator motor. It details factory wiring for 240V and instructions for changing voltage (240V to 208V, 240V to 460V) and rewiring the motor for high voltage (480V) or low voltage (240V) based on model (AR090 or AR120).
Notes:
- 1) All replacement wires must be same gauge and type.
- 2) To change voltage from 240V to 208V, move wire from 240V tap to 208V tap at transformer primary.
- 3) To convert voltage from 240V to 460V: a) Move wire from 240V tap to 480V tap at transformer primary. b) Identify model (i.e. AR090 or AR120) and rewire motor from low voltage (240V) to high voltage (480V) according to instructions below.
