  • Page 30: Heater For The Compressor And Control Cabinet

    3.1. Heater for the compressor and control cabinet The oil sump heater prevents the deposit of refrigerant in the oil when the temperature is low. When the compressor is started up this refrigerant would be liberated from the oil as gas and make the oil foam up. Under these conditions the lubrication of components subject to friction in the compressor would be poor, which could lead to the damage of the compressor.

    transmitter. This also switches off the compressors if the setpoint is exceeded, but releases them again if the value falls below the release value. Before switching off the, high-pressure transmitter signals a warning. Low pressure is also monitored by pressure transmitters. If the value falls below the setpoint the compressors switch off.

  • Page 42: Airborne Sound Emissions

    Cleaning and maintenance work in accordance with Chapter 10 Service. Before work is carried out on the chiller the protective equipment described in Table 7: Definition of the safety symbols must be used. Table 9: Personal protective equipment for servicing work Wear foot protection! Wear hand protection! Wear eye protection!

  • Page 43: Vibration

    Details of your chiller's airborne sound emissions are given in Chapter 4.7. To reduce noise pollution caused by airborne sound emissions it is advisable to install the chiller out of doors and out of the range of workplaces. If this is not possible we recommend that when the unit is installed attention is paid to ensuring that the air intake side is not pointed directly at a workplace/workstation.

  • Page 44: Dangerous Substances

    ATTENTION! Risk of suffocation if the chiller is installed in a room that is too small please note and follow chapter 6.2.2. ATTENTION! In the EU you must follow the provisions of EN378-3.
