Mounting on Top of the Enclosure
1. Make sure the enclosure design is capable of supporting the air conditioners weight. For interfacing air
“IN” and “OUT” openings, refer to Figure 4. Also refer to Dimensional Drawings on page 11.
2. To protect the integrity of the closed-loop design (see PRINCIPLES OF OPERATION), adhesive backed
gasket tape is provided (shipped loose) for sealing around the enclosures cutout openings. The gasket
may be cut to length and either adhered to the enclosure or to the air conditioner as shown in Figure
5.
3. A .5 inch (13 mm) inside diameter drain tube exists on the side of the air conditioner and must be
routed over the side. A pressure relief fitting has been provided to assist in venting any air blockage
that may prevent proper drainage. A copper “P” trap has also been included in the system and must
be properly primed and installed to prevent counter air flow into the drain system. The drain outlet
must not be submerged nor any portion of the drain system elevated above the exit point of the air
conditioner or overlapping of the condensate pan may occur.
