1 Unpacking and Handling
Burr caused by production may be present on the metal edges of the unit.
Always wear protective gloves when carrying out maintenance work and
installation.
Before and while you are unpacking the Enclosure Air Conditioner, you have to
conduct a visual inspection to determine whether the equipment has suffered
any damage during transport. Please pay close attention to loose parts, dents,
scratches, visible signs of oil loss, etc.
Any damage must be reported without fail to the transport carrier and not to
Pfannenberg Inc. (follow the Warranty policy,item 10).
Before disposing of the packing material, make sure that it does not contain any
loose components.
To facilitate warranty-claim settlement, please supply us with precise details of
the defect (with photo, if possible) together with details of model designation and
the unit serial number.
Do not place the unit directly on the floor as otherwise the condensate
drainage connection may be damaged.
In order to protect it against damage, the equipment may only be
transported and stored in its normal upright position. Failure to observe
this instruction will render the provisions of this warranty null and void.
2 eneral Information
In the event that is necessary to transport the complete enclosure with Air
Conditioner attached, we recommend that you detach the Air Conditioner and
transport it separately. When handling the unit, please grip only the housing or
the housing frame. Any work necessary on the unit may only be carried out by a
suitable qualified specialist. Compliance with applicable safety and
environmental regulations is imperative.
The Air Conditioner contain neither silicone compounds, PCB, PCT, asbestos,
formaldehyde, cadmium nor anti-wetting substances.
Every unit is checked to ensure that it is tight according to the provisions
of UVV-V B 20.
We hereby declare that, prior to leaving the factory, the unit was subjected to an
electrical safety check. This means that, in accordance with UVV-VBG 4, §5 (4),
the operating company is released from the obligation to arrange for a test of the
electrical part of the unit before taking the equipment into operation for the first

4 Application and Function
The Air Conditioner are designed to abduct heat from sealed switch cabinets.
Any other use shall be deemed as a deviation from the design use.
The units operate according to the principles of a heat pump with two airflow
circuits mutually isolated by mechanical means. The "internal airflow circuit"
draws off heat from the electrical and electronic components into the Air
Conditioner. The thus heated air is cooled and dehydrated inside the cooling unit
and then blown back into the switch cabinet interior.
The "external airflow circuit" makes use of the ambient air to cool the condenser
and thus expel the system's inherent heat into the atmosphere.
The fan in the "internal airflow circuit" is always in operation whenever voltage is
applied to the Air Conditioner. The thermostat in this circuit regulates the
compressor and the fan in the "external airflow circuit".
The air conditioner has been provided with an internal condensation removal
system (depending on the model, supplements). The enclosure air is drawn
across the evaporator pipes, it is cooled and dehumidified before it is blown back
into the enclosure. The condensation has been removed from the air and the
ambient air stream evaporates. The heat of the condenser pipes aids this
evaporation.
Although the unit has been designed to remove the small amount of the
condensation that will develop due to air infiltration into the sealed enclosure,
care must be taken to provide the proper drainage for the overflow drain of the
air conditioner. An overflow may occur if the air conditioner is operated for a
period of time with the enclosure unsealed, allowing moisture laden ambient air
to enter the evaporator section.
If water if found to be draining continuously from the overflow drain during
normal operating, this means that a significant quantity of moisture laden outside
air is entering the enclosure. Care should be taken to seal the enclosure against
such infiltration.
CAUTION :
Any effective cooling operation can produce condenser water. Therefore,
the Air Conditioner should only be fitted to sealed enclosures and only
operated with closed doors.
We recommend that you install a contact switch on the door of the
enclosure to cut out the cooling unit whenever the enclosure door is
opened.

8 Maintenance
• Before commencing with any maintenance and/or cleaning work on the Air
Conditioner, disconnect it from the electrical power supply.
• Do not place the unit directly on the floor as otherwise the condensate
drainage connection may be damaged.
• Apart from the occasional cleaning required on the condenser/ evaporator
assembly, the unit is virtually maintenance-free. The cleaning interval
depends entirely on the operating conditions (air pollution) and should by
determined by the user.
• You can clean the condenser/ evaporator either with a soft-bristled brush,
compressed air or, especially if it accumulates oily residues, with a high-
pressure cleaner. Please do not use any pointed or sharp-edged objects.
When cleaning, make sure that you do not press against the louvres or
damage them in any other way.
• Filter: The filter mat has to be cleaned (and, if necessary, replaced) at
regular intervals to be determined by the operating company solely in
accordance with ambient conditions (degree of air pollution).
Avoid wringing out the filter mat or aiming powerful jets of water at it!
You can rinse the filter mat out using water heated to 40°C and commercially
available mild detergent. It is possible to remove any dry dirt by knocking it
out, vacuum cleaning it or blowing it out.
