5.1. Cleaning condenser

Check once a month, or more often if necessary, that the condenser is clean.
Carry out the following procedures when necessary.
1. Vacuum the condenser fins and check that the spaces between the
fins are unobstructed.
2. Pull the top edge of the plate outwards and turn the plate downwards,
as indicated in the enclosed drawing.
If the controller unit indicates high pressure in the condenser, check
the condenser and clean it, if necessary. If the cabinet still doesn't
function normally after this procedure, contact service.

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
