They must be sent to one of our works shipment/postage •Prior to transport remove the cooling unit and pack it paid. • All cooling units produced by Pfannenberg are free separately if the complete switch cabinet is to be transported.
The compressor (1) compresses the refrigerant until high 6 Safety pressure is achieved. During this process temperature Cooling units produced by Pfannenberg are designed increases. In the condenser (2) heat is dissipated to for application dissipating heat from switch cabinets (IP ambient air, the coolant becoming liquid.
The condensate is discharged in the following way: To facilitate installation with heavy units, M8 lifting eyes •In case of normal condensate drainage a reservoir can be screwed into the upper fixing on the equipment housing. Simple‟‟ one man installation‟‟ is thereby (option) collects the condensate which is then drained by means of a hose.
Power supply connection: Both mains voltage and frequency must correspond to the nominal values indicated on the name plate of the cooling unit. Attention: The cooling unit may be damaged if the voltage is too high. It‟s nominal voltage is 230V or 400V. Door contact: In order to avoid any disruptive influences, it is recommended that a sheathed cable with twisted pair...
