- Press and hold the aux defrost button for 2 seconds to initiate the manual defrost procedure.
- Verify that the defrost light illuminates on the control panel to confirm activation.
- Ensure that melting moisture is not allowed to run through the drain hole into the evaporation pan.
- Always wipe the cabinet interior completely dry once defrosting is finished.
Monthly Condenser Filter Maintenance and Rear Safety
The condenser forms a vital part of the refrigeration system.
The condenser requires monthly cleaning to preserve efficient cooling.
In these upright cabinets, the condenser is located below the refrigeration cabinet.
These models feature a removable filter that can be cleaned with a vacuum cleaner.
Always disconnect the power supply before carrying out routine maintenance.
Failure to clean the condenser will reduce the performance and life of your unit and may invalidate your warranty.
Take care when cleaning the rear of the appliance because sharp edges can cut.
An authorised agent or qualified technician must carry out repairs if required on the unit.
- Disconnect the appliance from the electrical power supply before starting monthly routine maintenance.
- Access the condenser located below the main refrigeration cabinet.
- Remove the detachable filter positioned at the condenser assembly.
- Clean the removable filter thoroughly using a vacuum cleaner.
- Exercise strict caution around the rear of the appliance to avoid cuts from sharp edges.
