NOTE
§
In order to avoid heat loss you have to close the heated cupboards.
§
Connect the food transport trolley to the mains.
§
Switch on the appliance with the On / Off switch. The indicator integrated in the switch will light up to
show that the appliance is ready for operation.
§
Set the desired temperature using the thermostat of the heated cupboard. A continuous adjustment is
possible within the four power ranges. Digits engraved into the housing help to allocate the thermo-
stats to the corresponding heated cupboard compartments.
INFO
Use the heated cupboard as a cooling compartment
NOTE
The following must be considered when they are used as cooling compartment:
§
The heating of the cupboard compartment is switched off.
§
The temperature of the cupboard compartment corresponds to the room temperature.
§
The cold storage plate is completely frozen and is inserted into the uppermost pair of beads.
The duration of cooling is technically limited and dependent on the ambient temperature and the impact by
any heat sources (e.g. sunlight). The state of the cold storage plate has to be checked at regular intervals.
New cold storage plates have to be used regularly for longer cooling times.
When cold meals are kept properly, it is necessary to check and record the compliance of the prescribed
storage temperatures with appropriate measuring instruments (e.g. thermometer) before serving the meals.

Temperature setting
If the temperature of the heated cupboard is set too low, the food temperature
can drop to the value below the permitted limit of 149°F (65°C). This affects
negatively the food safety and stimulates quick bacterial growth.
Warm up the heated cupboard
If you warm up the heated cupboard, you can avoid that warm meals get cold.
Use of the cold storage plate
It is necessary to use at least one cold storage plate per compartment. The
cold storage plate has to be inserted horizontally into the uppermost shelf.
Warm meals should not be put into the appliance.
The temperature of the liquid-to-solid phase transition is 10.4°F (-12°C).
A constant cooling temperature of -0.4°F (-18°C) and a duration of cooling of
24 hours is recommended, since the cold storage plates must be completely
frozen in order to be fully effective and to significantly reduce liquid compo-
nents in the cooling brine. When you shock freeze them, the duration in the
appliance will be reduced. Please take into account the technical notes of the
respective manufacturers.
