These instructions are intended as an aid to qualified, licensed service
personnel for proper installation, adjustment and operation of this unit. Read

3.0 AIR HANDLER MOUNTING OPTIONS
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 a wall mounting bracket and air handler
mounting bracket. Reference figure 2 for more detail.
1. Remove the 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 remove the wall mounting bracket.
2. Install bracket one the wall by using 6 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. Life the air handler above the wall mounting bracket and attached the unit to
the installed bracket. Reference figure 2.
The air handler comes with 8 clearance holes 4 on each side. These holes are
used to mount the air handler inside of a frame structure (see figure 3). When
mounting in this fashion, make sure that the wood screws are mounted from
within the air handler and not outside of the unit. Installing the screws from the
outside of the unit, And notice don’t damage to the coil.
