NOTE: The coil must be installed with the line set and drain open-
ings to the front of the furnace or modular blower.
6.1 Duct Flange Attachment
There is no conversion required to reverse from right to left
application. Attach the duct flanges to the discharge side of
the unit. If the coil and furnace combination are not similar
in depth and width, use a field-supplied transition to center
the furnace and coil openings (see Figure 5B). The supplied
Z-bracket attachment should be used to attach the coil to a
narrower furnace with the furnace is one size smaller than
the coil (example: coil height is 21.0” and furnace width is
17.5”. See Figure 5C). Figure 5D indicates incorrect coil fur-
nace attachment method.
1. Prior to installation, remove the shipping bracket spanning
the A-Coil apex to the rear of the wrapper on all models.
2. The bottom duct flange for the supply plenum side is shipped
unattached. Carefully insert the flange into bottom rail and
use a 5/16" screw to attach at the middle of the flange.
3. Secure the side flanges with field procured 5/16” screws on
the supply plenum side.

5.3 Clearances
Refrigerant lines must be routed, depending on configuration
of unit, to maintain the required 24” minimum clearance for
service. Consult all appropriate regulatory codes prior to de-
termining final clearances. In installations that may lead to
physical damage (i.e. a garage) it is advised to install a protec-
tive barrier to prevent such damage. Always install units such
that a positive slope in condensate line (1/4” per foot) is al-
lowed.
NOTE: Furnace application requires that the installer MUST re-
view and strictly follow ALL furnace installation clearance guide-
lines. Failure to do so may result in property/equipment damage,
personal injury or death.
CONSULT ALL APPROPRIATE REGULATORY CODES WHEN DETER-
MINING FINAL CLEARANCES.
6 APPLICATION INFORMATION
Coils are designed for indoor installation only and must be installed
upstream (discharge air) of the furnace and downstream (return
air) of the modular blower. This coil is a bi-directional coil and can
be installed in either the left or right direction. Determine the coil
direction by the side that allows the best access.

Front View (For Right & Left Hand Applications)
Check horizontal level of the unit with spirit level. Don’t tilt the
unit down that makes it difficult to drain even though the level is
within criteria of spirit level. Such tilted units may cause water
leaks.
