Operating and Installation Instructions DTS Air Conditioner
1 Unpacking and Handling
Burrs 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 General 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 contains 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-VGB 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 time.
3 Technical Data and ID Plate
When carrying out installation and maintenance work, observe the data printed on
the ID plate located on the right-hand side of the Air Conditioner.

Operating and Installation Instructions DTS Air Conditioner
4 Application and Function
The Air Conditioner is 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.

5 Installation Instructions
WARNING: To avoid possible personal injury or property damage when the Air
Conditioner is to be mounted on door of cabinet, be sure that hinges will
support the added weight of Air Conditioner. Also be certain Air Conditioner
does not over-balance the electronic cabinet causing it to tip over when the
door is opened. Weight of the unit can be found on the ID plate. Use all
mounting holes to insure stability and efficient seal.
It is not necessary to remove the unit cover prior to installing the unit or setting it into
operation. The unit is operable immediately after applying the operating voltage.
5.1 Place the drilling template included in the scope of supply onto the outside
installation surface of the enclosure.
5.2 Drill the holes, and cut out the openings required for air transfer.
CAUTION:
Prevent steel filings from entering the switch cabinet.
5.3 Drive two stud bolts, included in the accessories, into both upper fixing points
next to the notice sticker with the instructions of the depth, at the backside of
the unit.
5.4 Place sealing strips around the cutouts of the enclosure.
5.5 Thread power and control leads through the air supply opening into the
enclosure.
5.6 Suspend the cooling unit on the enclosure by using the stud bolts.
5.7 Affix the cooling unit from the inside of the enclosure using the M6 bolts
included in the accessory package.
CAUTION:
The sealings have to be pressed to a thickness of 2mm / 0.08 inch.
5.8
Connect the cooling unit to the power supply.
5.9 An additional 5-core signal line is supplied on several units (circuit diagram,
supplement) and is used for wiring a door contact and floating contact that opens
whenever certain faults occur (e.g. excessive pressure in the cooling system, power
failure, cable breakage in the signal line). Max. load on contact: 5A.
CAUTION:
Both mains voltage and frequency must correspond to the ratings printed on
the cooling unit's ID plate. Work on electrical systems may only be carried out
by qualified personal, who are to observe the applicable safety regulations.

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.
