User menu

This chapter includes setting of alarm values. The alarm system is divided into 2 systems. The one system only triggers local alarms, which means that the error codes are only shown at the display. The other alarm system triggers both alarms at the display, but it also activates the remote alarm outlet. Each alarm system operates independently of each other.

Keylock

The keypad can be locked by simultaneously pushing + 1 for more than 5 seconds. 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 counter is operating under severe load (frequent door opening and frequent replenishment), manual defrosting can become necessary. Starting manual defrosting: push P + 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

Counters with compressor Defrost water is led through a pipe, from the evaporator and into a tray behind the condenser. Here, the water is evaporated by heat from the condenser. Counters connected to a common compressor The defrost water is led through a pipe to a tray behind the front panel, from where it is evaporated by a heating element.
It is recommended to clean the tray at least once a year. Remember to disconnect the counter before cleaning.

Power failure

In the event of a power failure, the control remembers the temperature setting and restarts the counter 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 counter will not work at optimum performance, or eventually it will be defective.

⚠ Before cleaning, the counter should always be disconnected.
⚠ Do not flush the counter 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 counter should be cleaned internally with a mild soap solution at suitable intervals and checked thoroughly before it is put into operation again.

Cleaning of counters with drawers: If the counter is equipped with drawers and the bottom, sides or back wall require cleaning, the drawers can be removed as follows (see Fig. 7a,7b,7c):

Pull out the drawer. Lift it up, after which the drawer can be pulled of the extension rails.

After cleaning, the drawer can be replaced. Place the drawer on the outer wheels on the telescopic rails. Lower the drawer into a horizontal position after which it can be pushed into a closed position. The drawer is now securely positioned.

Changing door hinge side

The door can be changed from righthand-hinged to left-hand-hinged or vice- versa. To do so, proceed as follows:

1. Remove the hinge at pos. A.
2. Lift off the door.
3. Remove the hinge at pos. B.
4. Move cover plugs in the cabinet from pos. D to pos. A and from pos. C to pos. B.
5. Move the cover plug in the door from pos. D to pos. A, too.
6. The hinge previously mounted at pos. A is now mounted at pos. C.
7. The door is now placed at the hinge at pos. C.
8. The hinge previously mounted at pos. B is now mounted at pos. D and adjusted, so that the door is closing properly. Then tighten the screws.

Door/drawer gaskets

This chapter deals with the importance of a well-functioning gasket. Gaskets are an important part of a refrigerator/freezer. Gaskets with reduced functionality, reduces the tightness of the counter. 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 counter.
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 counter 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. 9.
