Liebherr WKt 4552 GrandCru - Manual (Page 34)

34
In order to comply with the DIN 58345 standard, the MKv and MKUv models have the following specifications:
1) To avoid any unwanted manipulation, the set temperature is fixed at +5 °C to guarantee maximum safety
2) Likewise the offset values of the probes cannot be changed
3) Also alarm limits cannot be changed from the default values +2/+8°C
4) An additional probe is positioned at the warmest point within the unit and this temperature is displayed on the controller
5) The MKv 3912 has a load line to prevent pharmaceuticals being placed at the very top of the compartment
6) In order to prevent product loss or detriment due to incorrect storage, an integrated evaporator cover keeps products
away from the cold surface of the evaporator
7) The integrated power failure alarm gives an acoustic warning immediately upon power failure
Otherwise the MKv and MKUv models have the same features as the LKv and LKUv equivalents.
