Carefully unpack the unit and inspect the contents for damage. If
any damage is found at the time of delivery, proper notification and
claims should be made with the carrier.

The small air handler should be centrally located and may be
installed in a closet, alcove, utility room, basement. Minimum
clearances must be met.
The air handler comes standard with two different options for
mounting, wall mount or frame mount. Both mounting options require
the unit to be level from side to side and from front to back in order to
allow condensate to properly drain from the unit. Failure to do this will
result in condensate to leak out from the unit potentially causing
structural damage to the surrounding support structures, dry wall,
carpet, etc. around the unit. Also, both mounting structures require
the ability to accommodate a minimum of 150 lb load. Failure to do
this will cause damage to the support structure and potentially
damage the unit.
The air handler comes standard with an upper and lower wall mount
bracket. Reference Figure 3-1 for more detail.
1. Remove lower wall mounting bracket from the back of the unit by
removing one screw which attaches the bracket to the air handler.
Note: Discard the screw after you have removed the wall mounting
bracket.
2. Install bracket on the wall by using 3 wood screws (not provided).
Make sure the bracket is level in order to provided proper drainage
from the unit. Note: Do not attach the wall mounting bracket into
unsupported dry wall. Make sure that the wood screws are going into
a structure that can suppport a minimum of 150 lb load.
3. Lift the air handler above the wall mounting bracket and attached
the unit to the installed bracket. Reference Figure 3-1.
4. Install the additional bottom plate for extra support for this type
mounting (see figure 3-1).
Note: The additional plate is shipped in the bottom of the shipping
carton (only for 30/36k unit).

of the unit. Installing the screws from the outside of the unit, And
