4.8.1 Cleaning of the
condenser
(applies to devices with the integrated refrigerating unit)
The reason for frequent failures or malfunctions ofrefrigerating units may
becontamination of the condenser.
Cleanness of condenser is recommended to be checked at
least once a month. It is a user's obligation.
If necessary, remove the dust from the condenser ribs and
check for impurities blocking the air flow
and check for any obstacles between the ribs that hinder the air flow.
You can use a soft brush or a vacuum cleaner.
5. Power failure
Upon recovery of power failure or upon turning off and on the unit, it will start operation
automatically.
Upon recovery of power failure, check if the unit operates normally. If necessary, contact the
nearest authorised service.
6. Troubleshooting
In case of the unit or its component malfunction, or if it does not operate normally, it should
be checked if hazards to people and properties are not generated. If necessary, contact the
nearest authorised service point.
Prior to calling the service point, check if:
1. power is continuously provided;
2. the electrical system to which the unit has been connected is not damaged;
3. the unit is properly adjusted;
4. the condenser is not covered or contaminated;
5. products are properly arranged in the cabinet;
6. the air flow in the unit is not disturbed;
7. defrosting is not in progress – look at the controller and thermometer. In
case of the units equipped with controllers, in the course of de-frosting,
temperature indications on controller and thermometer may significantly
differ as the current temperature shown on the display is "blocked." When
uncertain if the unit is in the course or just upon completion of de-frosting,
wait for approx. 1 – 2 hours and check the temperatures one more time. if
the values are unchanged, this may indicate the malfunction of the unit.
If the cause of malfunction is not determined, turn off the unit and call the local authorised
service point.
