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 400 Btu, DC powered Air Conditioner unit is designed to be vertically on the front, rear
or side of your enclosure. See Figure 2.1.
Vertically mounted 400 Btu units are always mounted with the exposed heatsink fins at the
top and bottom and the terminal on the side. (Fig. 2.1) Vertical installations often require the use
of a Condensate Drip Pan (part # DP-140V) depending on a number of factors including internal
enclosure temperature, ambient temperature, humidity levels, quality of enclosure seals, and
frequency of enclosure opening.
We strongly recommend the use of a drip pan to protect the
electronics from dripping condensate.
(Fig. 2.1)
Mounting the unit with the fins pointing to either side will cause condensate to drip in an
uncontrolled manner, possibly damaging the air conditioner or electronic equipment within the
enclosure. If one of these orientations is the only possible configuration, contact the Engineering
Dept. at EIC for a custom solution.
Model AAC-140, DC powered, 400 Btu units
are not designed to be mounted on the top
of an enclosure. Doing so will allow condensate to drip in an uncontrolled manner from the air
conditioner on the inside of the enclosure damaging the air conditioner and the electronics
within the enclosure.
