SECTION 3: HANDLING
3.1 Transporting
The cooling unit shall only be moved in the fully
assembled condition.
If the cooling unit is being shipped with an electrical
panel enclosure it shall be packed separately from
the electrical enclosure.
3.2 Storage
The cooling unit shall not be exposed to
temperatures exceeding +70ºC.
If the device is stored or transported at temperatures
below freezing, the water circuit must be completely
emptied using compressed air.
WA R N I N G !
Failure to observe these requirements
will void the warranty.
SECTION 4: INSTALLATION
4.1 Pre-installation testing
Before mounting the cooling unit to the electrical
panel enclosure it should be tested to verify function.
Note: All devices are checked for leaks before leaving
the factory.
We recommend installing a door contact switch
to turn the device off when the electrical panel
enclosure door is opened.
4.2 Installation onto the electrical panel
Before connecting the cooling unit to the power
supply, verify that the following are correct:
Voltage must be within ± 10% of the value listed on
the ID plate.
Voltage frequency must be within ± 3 Hz of the value
listed on the ID plate
Ambient temperature must be below +55ºC (for
options see “setting the operating parameters”
section)
Place the drilling template supplied with the cooling
unit onto the applicable mounting surface of the
electrical panel enclosure.
WA R N I N G !
Metal chips from drilling and cutting the openings
may damage the electrical panel enclosure. Take
precautions required to prevent chips and debris
from getting into the enclosure.
WA R N I N G !
Watch out for sharp edges created when drilling
and/or cutting the enclosure.
Drill holes in the electrical panel enclosure to
match the unit and cut out air flow openings.
Install the two supplied stud bolts (in the accessory
pack) into the top two mounting hole locations of
the cooling unit.
