  • 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: 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 8: 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. The heat load to be dissipated from enclosure should not exceed specific cooling output of the unit at any condition.

  • Page 11 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 condensate formation is too great, additional condensate can drip into an overflow trough, which then drains off...

  • Page 12: Condensate Management

    9. Condensate management High humidity and low temperatures inside enclosures will cause condensation on the evaporator. Condensate that drips into the enclosure can permantly damage sensitive electronics and lead to malfunction. SLIMLINE PRO cooling units have an automatic electrical condensate evaporation with a self-regulating PTC heating element.

  • Page 21 Master settings Display Description Master On/Off Master Modes: None, Identical, Power Power Mode Delta Temperature MS2: Master Modes None: All units are Independent of each other. Each unit operates using its own setpoint and its own Internal Temperature. The Master still communicates with the Slave units to gather information in case information needs to be communicated to the Gateway.

The start-up units are settable.
  • Page 23 Setting rS3, Changeover Timeout, indicates the duration of each cycle. This can be a value from 1 to 9999 minutes. If a Slave needs to execute heating mode, Redundancy operation is ignored. If the Master needs to execute heating mode, the Slaves will keep operating based on the Redundancy Algorithm.
