CommissioningGEA CAIRfricostarELECTRICAL HAZARD AND DANGER FROM ROTATING UNIT PARTS ANDSHARP EDGES! OBSERVE PERSONAL PROTECTION MEASURES.In this connection make sure to observe the safety informationf on page 44.DAMAGE TO THE UNIT!Make sure that the evaporator or condenser is never exposed to ambient temperatureshigher than 60 °C (due to shutdown of the fan and/or water temperatures (heatingcoil) > 60 °C).The following commissioning steps must be carried out:• Protective gas charge must be available when making the connections.• Check that the configuration of the water inlet and outlet connections is correct.• Check that the shut-off devices and other fixtures have been correctly installed;counter flow principle with medium inlet on the air outlet side.• Check that pipe connections and mountings are secure.• Fill the refrigeration circuit with the medium for which the system was designed.• Check tightness of system.• Check that the the safety valves are functioning correctly.• Check the maximum temperature and pressure when the system is in operation(particularly when using R410A refrigerant)Saturation temperature = 60 °C/Bursting pressure: 38 bar.8.9 Heat pipeELECTRICAL HAZARD AND DANGER FROM ROTATING UNIT PARTS ANDSHARP EDGES! OBSERVE PERSONAL PROTECTION MEASURES.In this connection make sure to observe the safety information on page 44.Upright heatpipe:Horizontally installed heatpipe with fixed slope:Upright or horizontal withbypass damper control:The following must be checked during commissioning:The warm air flow (exhaust air) must be at the bottom and the cold air flow (fresh air)must be at the top.The warm air flow (exhaust air) must be at the bottom and the cold air flow (fresh air)must be at the top.For commissioning see „Dampres and shut-off dampers“ on page 49.48 PR-2006-0019-GB • Subject to modifications • Status 05/2009
