Introduction
Cooling unit for control cabinet is used for diminishing internal heat by
providing cool air to the control cabinet that can protect sensitive equipment It is
specially designed to resist surrounding temperature as high as 40-50 oC and can
function well in any factories including those with intensive dust, particles and oil mist
or with high acidity.

3. Notification
•Before, drilling, and cut. should use clean dry cloth, or the inventory doesn’t
lead the electricity, covers the equipment for protects iron dust touches the
electrical equipment while installing. (In case of machine still operate.)
•Cooling unit should be installed in the good circuration area
•Check vertical and horizontal level of which their error shall be allowable
within +/- 2 oin order to facililate efficient drainage
•Should always install gasket between Installation plate and Cooling Unit
before hang the cooling unit on the installation plate
•Installing of drain tube (Page 18)
•In order to minimize water condensation, cabinet doors should be tightly closed
during operation
•Circulation fan should be installed in cabinet if various equipment is densely
installed inside
•In order to obtain highest performance and durablility, repair and alteration of
cooling unit should be under care of distributor
•Should not adjust temperature difference more than 10oC betwee
enviromental temperature and cooling space, to prevent moisture build up on
some part in the cooling area when you open the cabinet panel
•If it is necessary to set temperature lower than 25oC, it is recommended to
use precision cooling unit or contact your Professional Maker.
•The equipments that are locate in the cooling air stream have to be
obstructed by the insulator to prevent water condensation
