This service manual does not include comprehensive operating
instructions for the user; it is only a further supplement to the
operating instructions.
It is intended for a trained service technician. As a result, many
important safety instructions for the user are missing with regard to 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 operatinginstructions.
This device is intended for the storage of packaged foods at a constant temperature. This device mustnot
be used to cool down or freeze foods.

Depending on the temperature and air humidity at the installation site as well as the selected setpoint
setting, the water 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 devices. As a result, a minimum distance of 30 to 50mm
must be kept between the devices 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.

The device must be placed on its back in order to remove the pallet beneathit.
Warning The device’s centre of gravity is located at the top by the machine box (top
heavy). At least two people are required to lay down the device and set it upright
again. Safety shoes and safety gloves must beworn.
Important If the device 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 device is on its back, the transport pallet must be removed by the following sequence;
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.

Cabinets on feet require an even, durable floor. Cabinets on feet are levelled byturning
the internal part of the feet (seefigure):
Cabinets on castors require a level, even and durable floor to provide a stable foundation. Aftercorrectly
positioning the device, the two brakes on the front castors must be applied (seefigure)
Devices on castors must not be placed on aplatform.
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 EN16825.
The actual amount of condensation water may vary depending on usage and ambient conditions. Ifthe
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 device
may have a defective door seal or a door that does not closeproperly.

The device must be cleaned regularly. The intervals depend on the usage and levelof
soiling (at leastannually).
When working with the electrical equipment, the device must always
be disconnected from the mains by pulling out the power plug. It is
NOT sufficient to switch off the device with the ON/OFF button as
parts of the device are still live
The cooling unit must not be sprayed with water –especially not with high-
pressure cleaners –as this can cause short circuitsand other damage to the
electrical system.
Cleaning agents containing chlorine or chlorine compounds as well asother
aggressive agents should not be used as they may cause corrosion of the
stainless surfaces and the internal coolingsystem.
The cooling system and in particular the condenser must be kept free ofdirt and
dust, for which a vacuum cleaner and a hard brush are most suitable.Take
special care not to damage the condenser wires and ventilation flaps during
cleaning.
The condensation water pan (at the top on the cabinet) as well as its drainage
path must be kept clean to ensure unimpeded drainage of the condensation
water. For cleaning condensation water pan authorized technical service
personnel can remove mono block cooling system and then can clean the pan.
The re-evaporation tray requires regular cleaning. (at leastannually).
The inside and outside of the cabinet must be cleaned at appropriateintervals
with a weak soap solution and checked for damage before the refrigeration unitis
put back into operation.
The outside of the cabinet can be cleaned using cleaning agents forstainless
steel.

The door hinge side can be changed without additional parts. The hinge brackets are asymmetrical, soyou
must take special care to not get them mixed up –if in doubt, label them before making the modification.
Since physical strength is required to change the door hinges on two opposite ends
of the door, the door hinge change should be carried out by two suitably qualified
persons for safety reasons. Otherwise, there is a risk of injury and damage tothe
device.
Change from DIN right to DIN left:
The door is turned by 180°, then the hinge brackets are moved diagonally, rotated by 180°. The doorcloser
is moved from the bottom right to the bottom left; the square with M8 internal thread is moved fromthe
top right to the top left.
