  • Page 4: Technical Information

    4. Technical information 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 7: Functional Principle

    5. Functional principle The cooling unit for enclosures works on the basis of a refrigeration circuit consisting of four main components: compressor (1), evaporator (2), condenser (3) and expansion device (4). The circuit is hermetically sealed and R134a refrigerant circulates inside it (R134a is chlorine free and harmless to the ozone layer).

  • Page 9: Mounting

    7. Mounting The power supply rating on unit rating plate must comply with mains rating. Always disconnect the power supply before opening the unit. The heat load to be dissipated from enclosure should not exceed specific cooling output of the unit at any condition.

  • Page 11: Taking Into Operation

    9. 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. before being connected to the mains and taken into operation.

  • Page 12: Maintenance & Cleaning

    11. Maintenance & Cleaning Always switch power supply off before starting any maintenance on the unit. The cooling unit is generally maintenance free and can be operated without filters in most environments. For units with filters these should be checked, cleaned and if necessary replaced on a regular basis.
