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. 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 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. To avoid having the
heating and cooling on at the same time, do not set the cooling thermostat below 70
°
F.
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.
Our 2500 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.
