GENERAL SAFETY INFORMATION
Please observe the following general safety instructions when assembling and operating the unit:
•
Assembly,installation and servicing may only be performed by properly trained specialists.
•
When transporting the enclosure with the cooling unit externally mounted, always use an additional shipping brace
to support the cooling unit.
GENERAL TECHNICAL INFORMATION
The evaporator outlet sensor monitors the enclosure return air temperature to prevent ice buildup on the
evaporator coil. If the air temperature drops below -1°C, the compressor and condenser air mover(s) shut off.
They turn back on when the temperature rises above 15°C.
The compressor and the air movers are equipped with overload protection to guard against excess current and
temperatures.
SEQUENCE OF OPERATION
The air conditioner comes standard with smart controller. During cooling modes, the evaporator fan will be
running.
COOLING
When the enclosure temperature is above the cooling setpoint, power is applied to the compressor and
condenser air mover(s).
Operating the air conditioner below the minimum ambient temperature or above the maximum
ambient temperatures indicated on the nameplate voids all warranties. DO NOT adjust the setpoint to a
temperature lower than 20°C. Doing so can increase the likelihood of frost buildup on the evaporator coil.
The moisture that the sealed enclosure air can contain is limited. If moistur�����
om the drain tube
continuously this can only mean that ambient air is entering the enclosure. Be aware that frequent
opening of the enclosure’s door admits humid air that the air conditioner must then dehumidify.
COMPONENT OPERATION
NOTE: Do not reduce the time delay setting on the controller to less than 120 seconds. This
may cause the compressor to cycle too rapidly, shortening the life of the compressor.
SMART CONTROLLER (GENERAL ALARMS)

REMOTE ACCESS CONTROL (OPTIONAL)
See Remote Access Control on page 21
DOOR SWITCH
If a door switch is available, connect it to the terminals marked WHT/DS1 and WHT/DS2. The switch
circuit should be open when the door is closed, and closed when the door is open. Several door switches
may be connected in parallel and operated on one cooling unit. The door switch only supports a ����
connection with no external voltages.
ACTIVE CONDENSATE MANAGEMENT
At low temperatures and high humidity levels inside the enclosure, condensation may form on the
evaporator coil.
Slim Fit air conditioners continuously evaporate the water that may be in the drain pan due to
condensation from the evaporator coil into the external air stream. Excess condensate is routed
downwards out of the air conditioner via a barbed ����
at the bottom of the condenser side of the unit. A
10 mm (.40) inside diameter tube can be attached to ��������°
outed to a nearby drain.
