OPERATION
3.1 THERMOSTAT SET POINTS AND HEATING/COOLING
UNITS
SETTING THE THERMOSTAT
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 in degrees
Fahrenheit. 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 fan will continue to run, circulating the air to maintain a uniform temperature within the
enclosure.
HEATING AND COOLING UNITS
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 just as it is with a cooling
only unit. Cooling will prevent the heating function from turning on. For example, if the cooling
thermostat is set to 40
°
F then the unit will cool to 40
°
F, then switch directly to heating until the
cooling turns back on.
If the air conditioner is operating in an ambient environment that may drop below 45F, it is not
recommended that the cooling thermostat be set lower than 50F. Setting the thermostat lower
than 50F in this environment could result in ice forming on the cold side of the unit.
3.2 MAINTENANCE
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.
Your AAC-145A-4XT air conditioner is 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 pressure washer can be used to carefully clean the hot side heat sink fins
when compressed air will not provide adequate cleaning. Never direct high-pressure water
at the fans. Never direct high-pressure water at 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.
