Product Description

The AHKD series of electric heat kits is an accessory designed for

installation with the Daikin DAR0904 or DAR1204 Airhandler ONLY.

For installation guidelines of the DAR0904 or DAR1204, refer to

the instructions which accompany the air handler, IOD-4010 (In-

stallation & Operating Instructions).

The AHKD provides supplemental electric heat for the DAR0904/

1204. The assembly is to be installed directly to the outlet of the

DAR0904/1204 and is not to be used as an independent duct

heater.

The AHKD20 and AHKD30 heat kits have two stages. A two stage

room thermostat determines the staging by room temperature.

The heat kit’s control panel is “self contained” and is equipped

with all of the safety circuit/limits required per UL1995. The heat

kit employs a terminal block for installation of the high voltage

wires used by both the heat kit and the airhandler (single point

wiring).
