1. GENERAL INFORMATION
1.1 PRINCIPLES OF OPER TION
n 1834 Jean Peltier discovered that by passing a current through two dissimilar conductors the junction of those
materials will either absorb or release heat depending on the direction of the current flow. Thirteen years earlier
Thomas eebeck had discovered that current would flow when you placed a temperature gradient across the
junction of two dissimilar metals. These two discoveries were the basis of thermoelectrics. With the advent of
modern semiconductors thermoelectric devices became practical for real world applications and are now found in
everything from consumer goods to spacecraft.
Your EIC olutions Thermoelectric Air Conditioner operates on this principle so there is no compressor and no
expensive, ozone depleting CFC’s. EIC’s air conditioners use Thermoelectric “modules” sandwiched between high
performance aluminum heat sinks, high CFM axial fans, and a patented electronic design to “pump” the heat from the
inside of your enclosure to the outside, without exposing your delicate electronics to any outside air or contaminates.
ee Figure 1.1.
EIC uses only the highest quality components in our air conditioners and you can expect years of trouble free
cooling from these solid-state devices. Every unit we sell is backed by our one year parts and labor warranty.

2. INSTALLATION
2.1 CHOOSING LOC TION 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 ORIENT TION
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. ee 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. ee 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 3 00 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 ection 2.1 of this manual.

2.3 PREP RING THE ENCLOSURE
To mount the 3500 Btu unit you will need to cut an opening in your enclosure and drill mounting holes. A cut-
out drawing (Fig. 2.3) showing the cut-out size and hole locations has been included in this manual (see Fig. 2.3). The
instructions for installing the air conditioner are printed below.
TOOL AND MATERIAL NEEDED:
•Pencil
•Tape Measure
•Jigsaw or suitable alternative
•Electric drill
•# 29 drill bit (.136”)
•# 8-32 tap and tap handle
•(24), # 8-32 x 3/8” stainless machine screws (supplied)
•(24) nylon washers (supplied)
•One neoprene gasket (supplied)
CUT THE OPENING AND DRILL MOUNTING HOLE IN THE ENCLO URE
1. Using the guidelines provided in the installation manual choose an appropriate location for the air conditioner
on your enclosure.
2. Layout the cut-out and hole pattern for the AC on the enclosure. Refer to Figure 2.3.
3. Before cutting or drilling check that the location meets the clearance requirements as specified in the
installation manual.
4. Using a pencil, center punch or other method, mark the exact center point of each mounting hole on the
enclosure
5. Using the jigsaw, cut the opening in the enclosure.
6. Using the # 29 drill bit, drill a hole at each of the marks you made earlier.
7. Using the 8-32 tap, tap each of the holes you have drilled.
2.4 INST LLING THE IR CONDITIONER
IN TALL THE AIR CONDITIONER
1. Lay the air conditioner down with the cold side (side with the thermostat) facing up.
2. Take the supplied gasket and lay it down on the flange.
3. Take one of the supplied mounting screws and, from the under side of the flange, push it up through the top
right mounting hole, and through the hole in the gasket. The gasket hole is undersized and will hold the screw
in place. Repeat this on the top left mounting hole.
4. et the AC unit in the hole you’ve cut in the enclosure, and using a screwdriver, carefully start the two screws
you attached to the gasket to the tapped holes in the enclosure. Do not tighten these at this time.
5. Install the rest of the screws in the flange placing a nylon washer on each fastener and screw them into the
tapped holes in the enclosure. Do not tighten them completely.
6. Remove the two starter screws and place a nylon washer on each and reinstall.
7. Tighten all screws.

2.5 INST LL THE DR IN LINES
1. Various hose fittings and a length of hose were provided with the AC unit. Review the Fig. 2.4 below for
suggested drain line configurations.
FIG. 2.4
YOU MUST USE THE FACTORY INSTALLED HORIZONTAL DRIP PAN IF YOU INSTALL THE AIR CONDITIONER
HORIZONTALLY (FIG 2.2) ON THE TOP OF YOUR ENCLOSURE. FAILURE TO DO SO MAY ALLOW CONDENSATE TO
DRIP IN AN UNCONTROLLED MANNER CAUSING DAMAGE TO YOUR EQUIPMENT.

2.6 PPLY POWER
Once the air conditioner is mounted, check the serial label and confirm the voltage required and then apply
appropriate power as outlined below.
220 – 240 VAC units – this unit will not have a plug on the end. Connect the wires to an appropriate power
source using standard safe wiring methods as follows:
Wire colors are as follows:
Black or Brown – line
White or Blue – line/neutral
Green or Green/Yellow – ground
Amperage for 220 VAC unit is 8.9 amps
Upon applying power to the air conditioner the fans on the cold side (inside the enclosure) will come on. The hot
side fans (outside the enclosure) may also run depending on where the thermostat is set. The cold side fans always run
to circulate air within your enclosure thereby eliminating any “hot spots”. The hot side fans will only run when the air
conditioner is cooling – they are “pumping” the heat from the inside of your enclosure to the outside air.

3. OPERATION
3.1 THERMOST T SET POINTS ND HE TING/COOLING UNITS
ETTING THE THERMO TAT
Your EIC air conditioner is equipped with an adjustable thermostat. The set point you choose should be based
on the desired internal temperature of the enclosure. The air conditioner will run until the set point temperature is
achieved within the enclosure and then the hot side fans and the thermoelectric cooling modules will shut down. The
cold side fans will continue to run, circulating the air to maintain a uniform temperature within the enclosure.
HEATING AND COOLING UNIT
If you purchased an HC unit (heating and cooling), the heater operation is controlled by a fixed-point
thermostat. This thermostat is set to turn the heaters on when the temperature within the enclosure falls to
approximately 45° F and turn the heaters off when the temperature rises to approximately 55° F.
The cooling operation is controlled by the adjustable thermostat. To avoid having the heating and cooling on
at the same time, do not set the cooling thermostat below 70° F.
3.2 M INTEN NCE
MAINTENANCE
EIC Thermoelectric Air Conditioners are virtually maintenance-free. The only time maintenance is required is
when a unit is installed in an extremely dirty environment. In these cases, the hot side heat sinks (outside the
enclosure) should be inspected regularly for a build-up of dust or dirt. If a build-up is present on the heat sink fins, it
can be easily removed as follows:
1. Disconnect the power from the unit.
2. Dry dust/dirt can be removed using compressed air to blow out the heat sinks. Do not direct any high-pressure
air at the fans.
3. Our 3500 Btu air conditioners are designed to allow for water wash down of the hot side of the unit, which is
outside of the enclosure (never the cold side which is inside the enclosure). A low pressure stream of water
can be used to carefully clean the hot side heat sink fins. Never direct high-pressure water at the fans or the
joint formed by the mounting flange, gasket and enclosure. Never allow the cold side of your unit to get wet.
Keeping the hot side heat sink fins free from any insulating build-up of dirt or dust will ensure long, trouble-free
operation of your air conditioner.
NEVER EXPOSE THE COLD SIDE OF ANY AIR CONDITIONER (INSIDE THE ENCLOSURE) TO WATER.
If you have any questions about any aspect of your EIC air conditioner, don’t hesitate to call us at the numbers listed
