Regular maintenance

Cleaning the inside and outside of the cabinet
Routine maintenance consists of the daily cleaning of all parts that are likely to come into contact with food. Good maintenance ensures better performance, longer service life and continued compliance with safety requirements.

• Use water and non-abrasive and non-aggressive neutral detergents. Do not use solvents and thinners.
• Wash with a soft sponge cloth with neutral non-abrasive products.
• Disinfection: avoid substances that may alter the organoleptic characteristics of the products.
• Rinsing: cloth or sponge soaked in water. Do not use water jets.
• A weekly cleaning frequency is recommended. The user can define different frequencies depending on the type of product stored.

Clean the seals regularly to prevent mould from forming. We recommend using a solution of water and NaHCO3.

• Do not use vinegar, aggressive or acidic products.

Cleaning the condenser
The condenser is the element that exchanges heat between the refrigerant gas and the surrounding environment. If the condenser becomes dirty or clogged, it will not work properly and the refrigerator will become less efficient. For these reasons, the condenser should be cleaned every month.

• Before any cleaning operation on the condensers, turn off the unit and DISCONNECT the power cable: danger of electric shock and/or exchanger fans in motion.

The condenser, located on the top of the appliance, can be accessed using a safety ladder. Use a jet of air or a dry brush to remove the dust and fluff that has settled on the fins using a vertical motion (Fig. 21). When finished, switch the cabinet back on.

• The following personal protective equipment should be used when carrying out this operation: safety goggles and respirator mask. The condenser has sharp parts and edges: wear protective gloves when cleaning it.

In the event of long periods of inactivity
A long period of inactivity means more than 7 days. Proceed as follows:

• Switch off the machine and disconnect it from the power supply.
• Thoroughly clean the inside of the cabinet, shelves, guides and supports, paying particular attention to critical areas such as joints and magnetic seals.
• Leave the doors ajar to prevent air stagnation and residual moisture.

Extraordinary maintenance, repairs
All maintenance operations that have not been described in the previous chapters are to be considered “extraordinary maintenance”.
Extraordinary maintenance and repairs must be carried out by qualified personnel who have been authorised by the manufacturer.

• We accept no liability for any work carried out by the user or unauthorised persons, or for the use of non-original spare parts.

The following operations should be carried out regularly by qualified personnel:

• Clean the condenser with suitable tools (vacuum cleaner or soft brush).
• Check that the door seal is in good condition, replace it if necessary.
• Clean the condensation evaporation tray regularly.
