  • Page 4: Settings

    4. Settings The cooling unit is intended to be used as a complementary accessory to larger industrial equipment. The unit is used where heat needs to be dissipated from electrical control cabinets or similar enclosures in order to protect heat sensitive components. It is not intended for household use. The unit has two completely separate air circuits which ensure that the clean cabinet air does not come into contact with the ambient air which may well be dirty or polluted.

  • Page 5: Functional Principle

    5. Functional principle The cooling unit for enclosures works on the basis of a refrigeration circuit consisting of four main components: compressor, evaporator, condenser and expansion device. The circuit is hermetically sealed and R134a refrigerant circulates inside it (R134a is chlorine free and has an Ozone Destruction Potential [ODP] of 0 and a Global Warming Potential [GWP] of 1430).

  • Page 8: Condensate Management

    8. Condensate management Durch hohe Luftfeuchtigkeit und niedrigen Temperaturen im Schaltschrank kann es zu Kondensatbildung am Verdampfer kommen. Kondensat welches in den Schaltschrank zurückfließt, kann empfindliche Steuerungselektronik beschädigen. Die integrierte Kondensatverdunstung des Kühlgerätes gibt das Kondensat an die Umgebung ab. Bei zu großer Kondensatbildung kann zusätzliches Kondensat in eine Überlaufwanne tropfen welches dann umgebungsseitig abläuft.

  • Page 19: Taking Into Operation

    15. Taking into operation Attention! The unit can be damaged by lack of lubricant. To ensure that the compressor is adequately lubricated the oil, which has been displaced during transport, must be allowed to flow back into it. The unit must therefore be allowed to stand for at least 30 min.

  • Page 20: Maintenance & Cleaning

    17. Maintenance & Cleaning Always switch power supply off before starting any maintenance on the unit. Wait for 5 minutes for electrical components to discharge. The cooling unit is generally maintenance free and can be operated without filters in most environments. If the ambient air is extremely dusty, we recommend installing filter mats (see accessories).

  • Page 21: Transport & Storage

    18. Transport & Storage Malfunction due to transport damage On delivery the carton box containing the unit must be examined for signs of transport damage. Any transport damage to the carton box could indicate that the unit itself has been damaged in transit which in the worst case could mean that the unit will not function.
