The installer must adhere strictly to all
local and national code requirements
pertaining to the installation of this
equipment.
Detailed instructions are shipped with all
accessory items and should be followed
in detail.
Air Handler Mounting
The air handler can be installed in any
direction. Its compact dimensions even
allows for installation between joists. The
air handler can be floor mounted or hung
from straps. Some precautions must be
observed for some of the possible
mounting positions.
For installations where the access door
faces up or down, select an air handler
with an external pump to avoid the pump
being mounted with its shaft vertical. The
pump shaft must be mounted horizontally
to avoid premature failure.
The air handler can be hung by securing
straps through any of the existing screw
holes in the cabinet. When the existing
screw is too short for securing a
mounting strap, a longer screw can be
used provided care is taken not to
damage any internal components.
When fastening straps using screws
other than those supplied with the
cabinet, special care should be taken in
the vicinity of the coil to avoid tube
puncture.
Warning!: Do not put screws into the
cabinet directly in front of and behind
the coil.
3/4” screws can be safely installed on
either side of the coil.
The cabinet is designed so that the
return air can be located on either side of
the cabinet, through the bottom of the
cabinet, or from the back. Position the
filter rack so that the filter is readily
accessible.
Install the air handler with the door firmly
screwed in place to make sure the
cabinet remains square.
Provide at least 2 feet (0.75 metres) of
service clearance in front of the access
panel of the air handler. Zero clearance
is acceptable on all other faces.
For vertical installations with a cased
cooling coil on the return,
install air
handler on a minimum 2” (50mm)
housekeeping pad
to allow room for
minimum 2” trap in the condensate drain.
This trap is necessary to prevent air
leakage through the drain. Refer to the
cased cooling coil installation manual for
more details.
Ductwork
General
Ductwork installed in unheated spaces
such as attics must be installed between
the insulation and the heated space.
Provide at least R-12 of insulation above
ducts. If cooling is required, the branch
and trunk lines must be insulated and
sealed with a vapour barrier prior to
applying house insulation.
If a fresh air duct is required, make
connection to return air plenum at least 6
feet (2m) upstream from filter. Insulate all
fresh air ducts.
