  • Page 2: User Manual

    1. User manual This instruction manual contains information and instructions to enable the user to work safely, correctly and economically on the unit. Understanding and adhering to the manual can help one: Avoid any dangers. Reduce repair costs and stoppages. Extend and improve the reliability and working life of the unit.

  • Page 3: Safety Instructions

    Disregarding the instruction manual Operating error Inappropriate work on or with the unit The use of non-specified spare parts and accessories Unauthorised modifications or changes to the unit by the user or his personnel The supplier is only liable for errors and omissions as outlined in the guarantee conditions contained in the main contractual agreement.

  • 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 Setting cooling set point, St1: 1. Press “SET” and display should show St1 and then the pre-set value of St1. (default: +35°C / +95°F) 2. Reach the desired value by using ▲ or ▼. 3. Press “SET” again to save the new value of St1. Setting heating set point, St2 (only for units supplied with internal heater): 1.
  • Page 6 Test function Different test functions can be used depending on the combination of keys pressed. Such tests run for the duration of 4 minutes. “SET+▲” tests Compressor and Ambient Blower relays. “SET+▼” tests Alarms and Heater relays Alarm Relay Operation Both normally closed (NC) and normally open (NO) alarm contacts are provided.
  • Page 7 Failure table: The display shows either ‘’OFF’’ or “EXX” with an icon flashing (triangle), alternating with the standard display. If more than one error occurs, these are shown in sequence on the display. Failure Description Solution Code Close the enclosure door and check the door contact switch. If no Door open door contact switch is used and c68=0, bridge terminals on power connector.

  • Page 8: Functional Principle

    5. Functional Principle The cooling unit for industrial enclosures works on the basis of a refrigeration circuit consisting of four main components; a compressor, an evaporator, a condenser and an 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 10: 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 12 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. The integrated condensate evaporation of the cooling unit releases the condensate to the environment. If too much condensation forms, the condensation is drained out of the cooling unit from the front through the lower gill grilles.
