INSTALLATION OF AN AIR CONDITIONING UNIT
The Caddy furnace has been tested with an optional air conditioning unit. If this option is chosen, we recommend an
installation as per the graphic provided below.
Damper
Damper
A/C coil
This installation will provide the most efficient and safe operation of the air conditioning unit using the distribution
blower of the Caddy furnace during summer. In order to complete the installation of an air conditioning unit, the main
thermostat must be a "heat/cool" type. Furthermore, the desired distribution blower speed must be programmed on the
touch screen in the blower speed menu. (See Section 16.5 DISTRIBUTION BLOWER SPEED CONFIGURATION)
Installing the A/C coil in the furnace fresh air return will create condensation inside the furnace and will make
it rust. Therefore, this type of installation is forbidden and will void the warranty.
It must be noted that upon thermostatic demand for cooling, the distribution blower will start immediately at the
programmed speed. For the air conditioning damper wiring see Section 33 - LINK BOARD OPTIONS
CONNECTIONS.
