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:

+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.

Warning The refrigeration unit is located at the top of the cabinet. At least two people
are required to lay down the cabinet and set it up right again.
Important If the cabinet has laid on its back or was transported horizontally, then it must
stand upright for at least two hours before switching it on to allow the oil to collect
inthe compressor.
Once the cabinet is on its back, the transport pallet must be removed by the following order;
1-2-3) 2 pieces of long wooden pieces at the bottom of the pallet are detached from the lower part of the pallet
with the help of a screwdriver from the left side of the refrigerator.
4-5-6) The other side of the long wooden pieces is moved to the right side of the refrigerator and detached from
the bottom of the pallet with the help of a screwdriver.

Then, 2 pieces of short wooden pieces at the back of the pallet are removed by hand. Once the pieces of wood that hold the
cabinet to the pallet are removed, it means the cabinet is no longer connected to the pallet.
10-11-12) With the help of a pallet truck or by means of 2 people, the cabinet is first tilted to one side from the pallet and
then the pallet is removed from the bottom.

Cabinets on legs:
Cabinets on legs require an even, solid floor. Cabinets on legs are levelled by turning the internal part of the feet.
Cabinets on castors:
Cabinets on castors require a level, even and solid floor to provide a stable foundation. After correctly
positioning the cabinet, the two brakes on the front castors must be applied.
The cabinets are equipped with a chamber for re-evaporation of the condensation water on top of the
cabinets. This equipment is intended for the amount of condensation water that accumulates on average
witha maximum of 72 door openings per day according to ISO 22041.
The actual amount of condensation water may vary depending on usage and ambient conditions. If the
number of door openings per day exceeds 72, or the condensation water pan overflows due to other usage
factors, the user must use the product strictly under the specified conditions to prevent overflow. If the
amount of condensation increases despite not changing the usage or the ambient conditions,the cabinet may
have a defective door seal or a door that does not closeproperly.

must be observed.
In order to achieve the necessary air circulation in the interior, only store goods within the corresponding
markings (loading marks) and on the shelves (never on the floor or in front of the air outlets).
