Location:
Please take care for a surrounding which is neutral in respect to the temperature – no heating
source directly nearby, no direct insolation. Rooms with elevated temperature respectively with
elevated humidity can cause the production of condensation water.
Power Supply:
The banquet trolley can only be connected to 230 V/50 Hz. Alternating current by a shockproof
socket which has been installed in accordance with regulations.
Operation:
Press the green rocker switch. The banquet trolley is ready for use as soon as the switch lights up.
The banquet trolley has got an electronic thermo regulator with digital display of set point and
actual point.

Defrosting:
The banquet trolley has got an automatical defroster with evaporation of condensation water. But
in spite of this there is still the danger that the evaporator gets covered by ice caused by influences
of the surroundings. We therefore recommend to check it every 2 weeks in respect to icing.
In case of icing, switch off the cooling until the evaporater is ice-free.
Cleaning:
It is advisable to clean the liquefier in the compartment of the cooling machine approximately every
3 months. An ice-free evaporator and clean liquefier facilitates to save engery.
For that the screen at the machine compartment between the wheels has to be screwed off. Free
the tubular system from dust by a vacuum cleaner. Remove fatty residues with cloth respectively
brush.
Current-bearing parts may never get in touch with water.
