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.
 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.
Operating conditions
The mains voltage must lie within the specified range; see
 A deviation of ± 10 % is permissible.
The rated frequency must be within ± 3 Hz of the value specified.
The ambient temperature must be below 55 °C. For further options, see
 The cooling unit must only be used in such a manner as to ensure that the specified cooling capacity is able to
meet actual demands.
 Only the specified coolant may be used.
NOTE
Spare parts from third-party manufacturers can damage the unit
Internal temperatures below the dewpoint or damaged switch cabinet seals cause excessive accumulation of
condensate.
➢ Only use specially agreed manufacturer parts for safe and reliable operation.
