6. 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 overflow during a power cut. After a power cut, check that the
cabinet operates normally. If necessary, contact your nearest service organisation.

7. 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 airflow in the cabinet is not disrupted.
• defrosting is not in progress, see the thermometer.
If the reason for the malfunction cannot be identified, 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 flow through the inlet and outlet grids is not obstructed by debris,
packaging waste or other such material. See section 4.4.1. Display messages

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.
In the event of a refrigerant leakage all products displayed in the cabinet must
be disposed of and then the cabinet must be cleaned.
