4.0 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.
4.1 WALL MOUNT
The air handler comes standard with a wall mounting bracket and air handler mounting
bracket. Reference figure 5 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
removed 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 support a minimum of 150 lb load.
FIGURE 5
ALL MOUNT
W
3. Lift the air handler above the wall mounting bracket and attached the unit to the
installed bracket. Reference figure 5.
4.2 FRAME MOUNT
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 6). When mounting in this
fashion, make sure that the wood screws are mounted from within the air handler and
ot outside of the unit. Installing the screws from the outside could cause damage to the
n
coil.
