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 17)
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

CORRECT INCORRECT
General Condition
Storage: Cooling unit should be stored at temp not exceeding 70 oC
Transportation: This type of cooling unit can't be laid down horizontally.
Installation: It shall be installed in vertical direction only
(please see figure below)
Disposal of damaged Cooling Unit
As its refrigeration system contain Refrigerant and lubricating oil for
compressor, in order to protect environment, these substances should be
disposed of properly or other under direction given by distributor.
4. Technical information
Protective equipment
Refrigeration system has been tested with high pressure device at 350 PSI.
This series of cooling unit also contains electronic circuit and sensors are
installed at significant points to monitor any defect of refrigeration cycle in order
to reduce burden of the user and to prolong use life of cooling unit at more
costeffective practice.
Note
- LED light will display green colour (continuously) to indicate condition.
- Under any abnormal condition, please see pages 20.
