3.1. Cleaning before use
1. Clean the cabinet surfaces and the storage compartment for foodstu󰀨s with a mild liquid
detergent (pH 6-8) before using the cabinet.
Follow the instructions provided with the detergent.
NOTE Make sure that all cleaning uids are classed as non-toxic.
2. Dry the surfaces carefully.
4. Electrical connections
NOTE The symbol marked on the cabinet (a lightning bolt inside a triangle) indicates
that there are components and wires under the cover containing live voltage.
Only personnel qualied to install and service electrical equipment are
permitted access to areas that contain live voltage.
Check the voltage and size of the fuse required on the rating plate attached to the cabinet.
The supply socket must be earthed and protected by a 10 A slow fuse. No other appliances
may be connected to the same fuse.
NOTE All electrical connections must be carried out by approved and qualied
personnel and comply with all IEE and local regulations, failure to do this could
result in personal or fatal injury.
5. Operation
Cooling is achieved by a fan evaporator system. The evaporator is located at the bottom of the
cabinet’s tray. Cold air is blown inside through the perforated side wall.
The cabinet is equipped with Danfoss ERC111A controller.
5.1. Starting up
1. Connect the plug to the supply socket.
The compressor and fans start operating.
2. Wait for 90 minutes or until the desired temperature is reached.
The cabinet is now ready to be lled.

5.2. Loading cabinet
• Position the products carefully.
• Do not ll the cabinet above the load limits marked in the cabinet.
See gure 2 on the inside cover.
• Do not exceed the load limit.
Exceeding the load limit will disrupt the designed airow pattern and cause the
temperature of products to rise.
• Do not drop or throw products into the cabinet.
NOTE The cabinet is not designed to cool down products but to maintain them at the
temperature at which they are placed in the cabinet. Food products warmer
than the specied temperature should not be placed in the cabinet.
5.3. Setting operating thermostat
The operating thermostat for the cabinet is located in the panel on the side of the cabinet’s
bottom part.
The thermostat is preset to the correct temperature of +5 °C at the factory for the open version.
For the glass lid version, the factory setting is +6 °C
5.4. Danfoss ERC111A control device
NOTE The type of the control device depends on the
cabinet
ERC 111A is a cabinet controller that directs the cabinet functions
and defrosting by means of temperature sensors.
5.4.1. Display messages
In normal status, the display shows cabinet temperature.
5.4.2. Checking temperature settings
Select the desired target temperature by pressing or .
The normal temperature view also reappears
if you do not touch any button for ve (5) seconds.
5.4.3. Defrosting
Start defrosting by pressing .
Thawing is fully automatic.

6. Cleaning
The following cleaning procedure must be carried out at least twice a year.
NOTE The cabinet must not be cleaned while the fans are running. To disable the
fans, disconnect the cabinet from the electricity supply.
WARNING Evaporators, condensers and parts made of stainless steel may have sharp
edges. Wear protective gloves and work cautiously to avoid cut injuries.
1. Disconnect the cabinet from the mains supply or turn the separate switch to the cleaning
position.
2. Demount lids if present. Empty the cabinet.
3. Allow the cabinet to reach the ambient temperature.
4. Remove any debris.
Do not use picks or sharp tools to remove ice from the evaporator. Damage to the coil may
lead to refrigerant leakage.
5. Inspect for drain water and remove it, if there is any.
6. Clean the interior surfaces of the cabinet with a mild liquid detergent (non-toxic, pH 6-8)
and dry the surfaces carefully using a clean towel.
7. When cleaning is completed, start up the cabinet. Mount lids if present.
See section Starting up.
Check at regular intervals also that
• the operating noise of the cabinet is normal,
• the evaporator is clean and
• the inlet and outlet grids are not obstructed or dirty.
NOTE Clean the drain sump located in the machinery compartment. Inadequate or
infrequent cleaning may shorten the service life of the electric heater / hot gas
piping for the drain sump. Detergent residues must be cleaned without delay
from the tray.
NOTE In the event of a refrigerant leakage all products displayed in the cabinet must
be disposed of and then the cabinet must be cleaned.
7. Interruptions in electricity distribution
The cabinet will start up automatically after a power cut or an interruption in the electricity
supply. The evaporation drain sump may overow during a power cut. After a power cut, check
that the cabinet operates normally. If necessary, contact your nearest service organisation.

8. Troubleshooting
If a defect occurs in the cabinet or cabinet equipment, or the cabinet does not operate normally,
check that this does not create a hazard to people or property. If necessary, disconnect the
cabinet and contact your nearest service organisation.
Before contacting a service representative, check that
• the plug has not come out of the supply socket and that the mains supply is working.
• the fuse for the cabinet is intact.
• the cabinet is correctly positioned.
• the condenser is not blocked or dirty.
• the products are placed in the cabinet correctly.
• the airow in the cabinet is not disrupted.
• defrosting is not in progress, see the thermometer.
If the reason for the malfunction cannot be identied, disconnect the electrical supply to the
cabinet and contact the service organisation.
Check at regular intervals that the operating noise of the cabinet is normal, the condenser and
evaporator are clean, and the air ow through the inlet and outlet grids is not obstructed by
debris, packaging waste or other such material.
9. Servicing and spare parts
The specications of the cabinet are marked on the rating plate, see the inside cover. Please
inform your authorised service organisation of the cabinet type, name, serial number and
the Control markings marked on the rating plate. The rating plate and the wiring diagram are
located behind the ventilation grating close to the digital controller. The service periods of the
cabinet are dened in a service contract.
NOTE Only authorised tters may carry out servicing and repair of the machinery
and electrical equipment in the cabinet. The evaporator should be cleaned by
authorised service personnel.
It is recommended to use Viessmann spare parts.
