  • Page 3: Legal Regulations

    2. Legal regulations Liability The information, data and instructions contained in this instruction manual are current at the time of going to press. We reserve the right to make technical changes to the unit in the course of its development. Therefore, no claims can be accepted for previously delivered units based on the information, diagrams or descriptions contained in this manual.

  • Page 4: Safety Instructions

    3. Safety instructions Upon delivery the unit is already meeting current technical standards and can therefore be safely taken into operation. Only authorised personnel is allowed to work on the unit. Unauthorised personnel must be prohibited from working on the unit. Operating personnel must inform their superiors immediately of any malfunction of the unit.

  • Page 5: Settings

    4. Settings Air - water heat exchangers are intended as complementary accessories to large industrial equipment which include a motor-operated fan or blower together with a cooling heat exchanger. These may also include an electric heater. The fan or blower is intended to recirculate air and allow heat exchange. The heat exchanger is designed for chilled water or anti-freeze/corrosion inhibitor mixed water from a separate source.

  • Page 6: Functional Principle

    5. Functional principle The air inside the control cabinet is moved over a laminar heat exchanger through which a coolant medium runs, making use of the counter-flow principle. The fan blows the warm air along the aluminium fins of the heat exchanger;...

  • Page 9: Mounting

    8. Mounting The power supply rating on unit rating plate must comply with mains rating. Always disconnect the power supply before opening the unit. SLIMLINE HEX air/ water heat exchangers have an extremely compact design and construction, giving them the advantage of occupying very little space.

  • Page 10: Condensate Management

    9. Condensate management High humidity and low temperatures inside the enclosure can lead to condensation on the evaporator. Condensate that flows back into the enclosure can damage sensitive control electronics. If too much condensation forms, the condensation is drained out of the cooling unit from outlets in the front bottom cover (Position 1, 3 and 4) or directly through the bottom of the unit (Position 2).
  • Page 11 Remove the sealing panel. Remove only the lower sealing panel on the RK-7525 and RK-7555. Take the grommet supplied in the packing bag and insert in the bottom panel. Insert the drain hose from the bottom of the unit and keep pushing until it is fully inserted in the drain fitting.

  • Page 12: Mounting Principle

    10. Mounting Principle Unpacking unit: Please follow the below steps to unpack the unit. STEP 1: Stand the cooling unit upright with the pre-cut packaging opening facing up. STEP 2: Pull off the packaging opening. STEP 3: Hang the transport loop of the unit in the transport hook and lift it slightly. STEP 4: Pull off...
  • Page 13 The cooling unit can now be attached to the enclosure. 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 14 Dual air outlet option: Some of the variants of the Slimline HEX units have the option to have the air outlet in two positions to cater for the enclosure on which the unit is installed. The factory setting is to use the upper air outlet. To change over to the lower air outlet the dual closing panel has to be unscrewed and re-installed at the upper position.

  • Page 23: Taking Into Operation

    15. Taking into Operation The cooling performance of the heat exchanger is dependent on the water flow rate available from the supply. The water flow is dependent on the water supply system to which the heat exchanger is connected and is affected by various factors, such as conduit pressure, conduit diameter, etc.

  • Page 24: Maintenance & Cleaning

    16. Maintenance & Cleaning The unit should have regular functional tests (approx. every 2,000 hours depending on the grade of ambient pollution). 17. Maintenance Every unit is given a performance test under load at the factory. The units are largely maintenance-free, however, the following points should be observed: 1.

  • Page 25: Transport & Storage

    18. Transport & Storage Malfunction due to transport damage. During transport and storage the heat exchanger must be kept in the position marked on the box and at a temperature between -40˚C and 70˚C and a relative humidity of max. 95% (at 25°C). Check the packaging has not been damaged during shipping.
