Installing Duct Collars
Duct collars are supplied with the unit and are attached to the sup-
ply and return openings with the flanges to the inside and must be
reversed before unit's installation.
1. Remove the screws from the collars and reverse them so
the flange is to the outside.
2. Make sure when pushing the collars into place that the "V"
flange of the collars seats into the supply and return holes
securely.
3. Re-install screw in each collar so it goes through both of the
holes in the collar end. It does not matter how the ends of
the collar overlap in order to accomplish this.
Installation
CAUTION
The unit must be installed as level as possible, with a maxi-
mam slope no greater than 1/8" per foot (lOmm per meter).
For side to side leveling, the condensate drain side of the
unit MUST always be lower to provide proper drainage.
The unit MUST be situated in such a way as to provide safe
access for servicing.
The platform may be made of either concrete or pressure
treated wood and MUST be level and strong enough to
support the unit's weight.
Position platform separate from the building's foundation.
Install in a well-drained area, with the top surface of the
platform high enough above grade level to allow installa-
tion of a condensate drain trap. See FIGURE 4
