1. It is recommended that a lift truck be used for installation.
2. Adjust the lift truck height so that the heat exchanger is located
in line with the cutouts and mounting holes.
3. Route the power cord through the air cutout.
4. Move the heat exchanger toward the enclosure panel so that the
gap between the heat exchanger and the enclosure is about
.05-inch.
5. Install sealing washers on each screw from inside the enclosure
and tighten (see mounting drawing).
The Kooltronic Water-To-Air Heat Exchangers 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 the mounting 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:
