INSTALLING THE UNIT
The air handler can be installed in a vertical or horizontal (left
only) configuration as shown below. The units are designed for “0”
zero clearance to combustibles. 24” is required for service access
to the front of the unit. (See below) Regardless of mounting
configuration, the air handler must be mounted level to facilitate
proper condensate drainage.
