VII. Specific Model Data

Mounting

The Kooltronic Special Purpose Air Conditioners K_NA4C3P21R have been engineered to be installed easily.
These units utilize double layer gaskets. The first gasket layer is placed on the outside perimeter of the front panel
that is sealed against the customer enclosure. The second layer is placed on the two cutouts in the front panel.
The first gasket layer will allow a small amount of water between the two layers. The second gasket layer totally
protects an enclosure from ambient air, rain or hose down water. This gasket arrangement assures the integrity of
the closed loop system and is necessary to maintain the NEMA 4 rating.

Prior to mounting, refer to page 8 for the general arrangement drawing showing dimensions and locations of
mounting holes and cutouts. Prior to cutting or drilling, make sure that cutouts and mounting holes do not interfere
with components inside the cabinet. To avoid damaging your air conditioner, please read the following information
before installation:

CAUTION

If the air conditioner is mounted to the cabinet door you must be sure that the door hinges will

support the additional weight of the air conditioner. Also be certain that when the door is

opened fully, the cabinet does not become unbalanced. The actual weight of the unit can be

found in the performance specifications.

plate bottom flange and the enclosure panel. Install sealing
washers and stainless steel nuts on each screw from inside the
enclosure and tighten (see mounting drawing).
