SECTION 2: RECEIVING INSPECTION
2.1 Unpacking
Prior to and during unpacking the cooling unit,
visually inspect it to determine if any damage has
occurred during shipping. Make sure that it does not
contain any loose components. Before discarding
any packaging materials: Look for loose parts, dented
or scratched panels or fluids.
If any damage is noted it shall be reported
immediately to the delivering carrier and a claim
should be filed with them. Pfannenberg cannot
accept responsibility for freight damage that may
occur; we will assist you in any way possible if the
need arises to file a claim.
In case of a warranty claim, the following information
is required: exact details of the fault (including
photographs, if possible), the cooling unit part
number and serial number are required.
W A R N I N G !
Burrs caused by production may be present
on the metal edges of the cooling unit. Always
wear protective gloves when carrying out
installation or maintenance work.

SECTION 3: HANDLING
3.1 Transporting
The cooling unit shall only be moved in the fully
assembled, upright condition.
If the cooling unit is being shipped with an electrical
panel enclosure it shall be packed separately from
the electrical enclosure.
W A R N I N G !
If for any reason the cooling unit has been
placed in any position other than fully upright
it shall be placed in a vertical position for a
minimum of 1 hour prior to starting the unit. If
this is not done the compressor may be drained
of oil. Operation of the compressor without
proper oil fill may cause permanent damage to
the cooling unit and 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.
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.
3.2 Storage
The cooling unit shall not be exposed to
temperatures exceeding +70ºC. Store the unit fully
assembled in the fully upright condition.
W A R N I N G !
Failure to observe these requirements
will void the warranty.
W A 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.
W A 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.
Remove the cooling unit cover for handling during
installation by removing the cover mounting screws.
Install the two supplied stud bolts (in the accessory
pack) into the top two mounting hole locations of
the cooling unit.
W A R N I N G !
Please note the information on the “Thread
Reach for Set Screw” label attached to the
cooling unit. If the noted installed thread depth
is exceeded the cooling unit may be damaged.
