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 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 can be controlled by
a second adjustable thermostat.
You must set the heating thermostat set-point at least 10
degrees lower than the cooling thermostat set-point to prevent both the heating and the
cooling from operating at the same time.
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 fan.
3.
NEMA 4X models of our 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 pressure washer can be used to carefully clean the hot side heat sink
fins. Never direct high-pressure water at the fan or the joint formed by the mounting
flange, gasket and enclosure. Never allow the cold side of your unit to get wet. Always
check your serial label before proceeding with a water wash down.
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.
ONLY NEMA 4X UNITS, WITH MODEL NUMBERS BEGINNING WITH “AAC-140-4XT”, ARE
DESIGNED FOR THE HOT SIDE OF THE AIR CONDITIONER (OUTSIDE THE ENCLOSURE) TO
TOLERATE EXPOSURE TO WATER.
NEMA 12 UNITS, WITH MODEL #’S BEGINNING WITH “AAC-140-T”, ARE NOT DESIGNED TO BE
EXPOSED TO WATER AND SHOULD NEVER BE WASHED DOWN.
NEVER EXPOSE THE COLD SIDE OF ANY AIR CONDITIONER (INSIDE THE ENCLOSURE) TO
WATER.
