lights to indicate that the keys are locked, and a short beep sounds. Now it is not possible to use the keys for temperature setting etc. The same code is to be used for unlocking the keypad again.

Defrosting

Defrosting is automatically performed 4 times every 24 hours. If the cabinet is operating under severe load (frequent door opening and frequent replenishment), manual defrosting can become necessary.

Starting manual defrosting: push simultaneously for more than 3 seconds.

The next defrost will occur 6 hours later. lights up to indicate a defrosting cycle.

It is possible to change the number of defrosts. See the chapter "User menu" for setting.

Do not use sharp or pointed objects to accelerate the defrosting process.

Defrost water

The cabinet expels defrost water during defrosting, which is led into a tray on the backside of the cabinet (see Fig. 6).

A re-evaporation pipe from the refrigeration system, and an electrical heating element, placed in the tray, re-evaporates the water.

Some models are equipped with a condensate pump, which pumps the water up into a tray in the compressor compartment, where it is re-evaporated..

It is recommended to clean the tray and water trap at least once a year. Remember to disconnect the cabinet before cleaning.

Be careful not to damage the re-evaporation pipe and heating element during cleaning.

Fig. 6

Power failure

In the event of a power failure, the control remembers the temperature setting and restarts the cabinet when power is restored. If the power failure persists for some time, the control might revert to the factory setting.

Cleaning

Insufficient cleaning will cause that the cabinet will not work at optimum performance, or eventually it will be defective.

Before cleaning, the cabinet should always be disconnected.

Do not flush the cabinet with water, do not use water jet or steam hose as this may cause short-circuits in the electrical system.

Cleansing agents containing chlorine or compounds of chlorine as well as other corrosive means, are not to be used, as they might cause corrosion to the stainless panels of the cabinet and the evaporator.

The compressor compartment and in particular the condenser must be kept free from dust and dirt. This is best done with a vacuum cleaner and a brush.

The air filters on the condenser and the front panel can be removed and cleaned in a dishwasher at max. 50°C.

For the external maintenance – use stainless steel polish.

The cabinet should be cleaned internally with a mild soap solution at suitable intervals and checked thoroughly before it is put into operation again.

Door gaskets

This chapter deals with the importance of a well-functioning door gasket.

Gaskets are an important part of a refrigerator/freezer. Gaskets with reduced functionality, reduces the tightness of the cabinet. Reduced tightness might cause increased humidity, internal icing, an iced up evaporator (leading to reduced refrigeration capacity), and in worst case reduced lifecycle of the cabinet.

Therefore it is important to be aware of the condition of the gasket. Regular inspection is recommended.

The gasket should be cleaned regularly with a mild soap solution.

If a gasket needs replacement, contact your supplier.

Long term storage

If the cabinet is taken out of operation, and need to be prepared for long-term storage, clean the inside compartment, the door and door gasket thoroughly with a hot soapy damp cloth.

Eventual remnants of food could create mould.

Service

The refrigerating system and the hermetically sealed compressor require no maintenance - they merely must be kept clean.

If refrigeration fails, first investigate whether the unit has been unintentionally disconnected or switched off at the socket, or whether a fuse has blown.

If it is not possible to find the cause of the refrigeration failure, please contact your dealer.

When reporting a malfunction please state the type and serial number (S/N) of the cabinet. This information is found on the name plate, see Fig. 7.
