This service manual does not include comprehensive operating instructions for the user; it is only a further
supplement to the operating instructions.
It intends for a trained service technician. As a result, many important safety instructions for the user are
missing about the scope and readability. In case of doubt, please observe the information in the operating
instructions for transport, installation, operation, and electrical safety and never pass on this service manual in
place of the operating instructions.
This cabinet is intended for the storage of packaged foods at a constant temperature. This cabinet mustn’t
be used to cool down or freeze foods.
Area of application:

+30°C with %55 RH

+40°C with %40 RH
The cabinet must be installed in a dry, well-ventilated room away from direct sunlight at a sufficient
distance from radiators and other sources of heat. Please always consider the waste heat of all cabinets
installed in one room!
The ambient temperature must lie between a minimum of +16 °C and a maximum of + 40°C. A gap of at
least 50 cm must be kept between the top edge of the machine compartment and the ceiling. The air
exchange in this area must not be obstructed from the front or the side by screens etc. hanging from the
ceiling.
For electrical safety reasons, the cabinet must not be operated outside. The refrigeration technology of the
cabinet does not function outside or in unheated rooms (particularly in colder seasons) and can be damaged
by low temperatures.

Depending on the temperature and air humidity at the installation site as well as the selected setpoint
setting, the moisture in the ambient air can condense on the surface of a refrigerating unit due to itsdesign.
If several cooling or refrigeration units are set up side by side, this condensation effect becomesstronger,
and a lower air quantity can circulate between the cabinets. As a result, a minimum distance of 30 to 50mm
must be kept between the cabinets depending on the temperature and airhumidity.
These gaps must not be sealed either at the top or bottom, but can be covered by a stainless-steelpanel
from the front for aesthetic purposes. The panel must be removable for cleaning within thegaps.
If it is not possible for air to circulate freely at the bottom, e.g. due to a base installation, then thegaps
cannot be sealed at the front.
