4.4 Operation of the cooling unit
• After connection of the mains voltage, the device switches to startup/test mode or directly to operating mode.
The controller equipment determines which mode is activated.
• In operating mode the cooling unit switches to cooling mode as needed. This takes place depending on whether
a temperature switching threshold (TSet) is reached or undercut.
 Cooling mode switches off when the temperature switching threshold (TSet) is undercut. It continues running if
the temperature switching threshold (TSet) has not been reached yet.
 The evaporator fan (internal), condenser fan (external) and compressor switch off when the door is opened.
NOTE
Condensate flowing back into the switch cabinet can damage the electronic components
Internal temperatures below the dewpoint or damaged switch cabinet seals cause excessive accumulation of
condensate.
 Regular inspection of the seals assures protection against heavy condensate accumulation.
 Ensure that the accumulating condensate can drain freely.
