2-1 Caution
Danger
For prevention of electrical shock, power supply to the control panel should be
disconnected before installation work.
Caution
For installation, do not use any parts other than originally supplied ones.
Failure to this may result in injury or breakdown of the cooling unit.
In case screws are used for installation instead of the original bolts,
put a plate between the screw and the cap nut so as the direct torque not to
be transmitted. Or, the cap nut may cause slipping.
Cut out the mounting surface of the enclosure as specified in the drawing of page 8.
COOLCABI must be placed horizontally and
perpendicularly within a tolerance of
±
2
⁰
in order
to keep stable operation of the unit and
to make a smooth drainage.
Locate the unit so as to assure good ventilation
and distance of at least 200mm from the walls or
other units.
Also, there should be no hindrance to the air
circulation inside the control panel.
Failure to the above may result in poor cooling
performance or condensation.
The supply voltage must be as specified on the rating
plate of the unit.
Electrical connection should be made via appropriate
circuit breakers as shown in the right.
Ground the wire without fail to prevent electrical
shocks
Electrical works required for installation of the unit must be done only
by specialists.
Improper installation may result in electrical shocks or fires.
For protection of the compressor, wait at least 30 minutes after installation
before connecting power to start operation.
Hermetically seal the control panel all round.
Inferior sealing may cause condensation which lead to poor cooling efficiency.
Put covers on the components inside the enclosure to protect them from
cutting dust during installation work.
[Short circuit]
Electric components or other objects near the cool
air outlet may disturb cool air circulation. If the cool
air hit against them, it will directly return to the
suction port without being distributed to the whole
area in the enclosure. This causes not only troubles
of the components but may negatively affect
operation of the cooling unit which lead to
overcurrent and product failure.
In case such short circuit is found during cooling
operation, improve the environment by attaching
rectifying plates or installing agitation fans as
necessary.
