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) 2500 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-151-4XT 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 to 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 2500 Btu units
always require a factory installed drip pan (part #
DP-151H) 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.
