2. INSTALLATION
2.1 CHOOSING A LOCATION ON YOUR ENCLOSURE
When choosing a mounting location for your unit, be sure to keep air flows of both the interior and exterior
heatsinks and fans in mind. Adequate clearance between the fans/heatsinks and nearby surfaces is required for
unrestricted air flows which will ensure optimal performance and long, trouble free operation. The general rule is to
allow a minimum of two inches between the fans or heatsinks and any surface. Refer to figure 1.1 for an air flow
diagram.
Other considerations in deciding on a mounting location include; allowing access to thermostat (this will be
inside the enclosure) if frequent adjustments are to be made; allowing access to the hot side heat sinks (this will be on
the outside of the enclosure) for cleaning if the unit will be used in a harsh, dirty environment.
2.2 ORIENTATION
Your AC unit can be mounted either vertically on the front, rear or side of your enclosure or horizontally on the
top of your enclosure. See Figure 2.1 and 2.2.
Vertically mounted (mounted on the side of an enclosure) 3500 BTU units are always mounted with the exposed
heatsink fins facing left and right. (Fig. 2.1)
The unit cannot be mounted vertically and turned 90 degrees with the
exposed heatsink fins at the top and bottom.
The AAC-161B-4XT is equipped with a built-in vertical condensate drip
pan. Once installed the drain hoses must be attached to the brass fittings located in the bottom of the cold side cover
(inside the enclosure) and routed outside the enclosure. See Fig. 2.1.
Mounting the unit vertically and turned 90 degrees on the side of an enclosure (with the exposed heat sink fins
facing the top and bottom), will cause condensate to drip in an uncontrolled manner, possibly damaging electronic
equipment within the enclosure. If this orientation is the only possible configuration, contact the Engineering Dept. at
EIC for a custom solution.
Horizontally mounted 3500 Btu units
always require a factory installed drip pan (part # DP-161H) to
prevent dripping condensate from damaging electronic equipment.
(Fig. 2.2)
In either orientation, issues regarding access should be considered and minimum clearances must be
maintained as outlined in Section 2.1 of this manual.
