General notes

Safety instructions

PLEASE READ AND FOLLOW THESE INSTRUCTIONS

This detailed design guide contains warnings and important notes. These instructions contain information for planning and for efficient, safe installation. Always read and follow all warnings and important notes.

! WARNING! Warning indicates a potentially hazardous situation which could result in death or serious injury if the warning is not observed.

IMPORTANT An important note highlights information that is especially relevant to a problem-free installation and operation.

Electrical requirements and safety

Only operate the appliance with alternating current (AC). The maximum voltage and frequency depend on the appliance design for the country concerned. Sockets must be properly earthed and protected by a fuse. Sockets must not be situated behind the appliance and must be easily accessible to disconnect the appliance from the mains if necessary. A separate circuit for the appliance is recommended to prevent food defrosting or spoiling due to a power failure caused by other appliances.

! WARNING! Risk of fatal electric shock. Do not connect the appliance to unearthed sockets. A failure to obey this instruction may result in serious injury or death.

! WARNING! Danger of fire. Do not connect the appliance using an extension cable or extension socket. There is a danger of overheating and fire as a result of possible poor socket contacts. Do not connect the appliance using an inverter. There is a danger of overheating – resulting in fire – of the electronic control system as a result of incorrect sinusoidal voltage from various inverters. A failure to obey these instructions may result in fire, serious injury or death.

IceMaker

The IceMaker is fitted in the freezer compartment of the combined refrigerator-freezer. It must be connected to the mains water supply to work. The appliance must be levelled to ensure that all the chambers in the ice-cube tray of the IceMaker are completely filled with water. See the section entitled Water connection for IceMaker for further details.

Requirements for installation

Check the following:

• Is the floor designed to withstand the net weight of the appliance plus the weight of complete contents? The net weight of the appliances is as follows: ECBN 5066 > 147 kg, EC(B)N 6156 > 163 kg, EC(B)N 6256 > 159 kg
• Is the floor level?

IMPORTANT Do not start the appliance for 1 hour after transport so that the lubricant in the compressor can collect in the compressor housing and cannot get into the refrigerant circuit.

Anti-tipping device

The anti-tipping bracket supplied with the appliance must always be installed to prevent the appliance tipping over when the fully loaded door is opened.

Range of appliance use

The appliance is suitable solely for storing food in a domestic environment or similar. This includes, for example, use in private homes, staff kitchenettes, bed and breakfast establishments, by guests in cottages, hotels, motels and other forms of accommodation, in catering and similar services in the wholesale trade.

The appliance is not suitable for storing and cooling medicines, blood plasma or laboratory preparations. Incorrect use of the appliance can cause the stored goods to be damaged or spoiled. Furthermore, the appliance is not suitable for use in explosion-hazard areas.

Climate rating

The climate rating indicates the room temperature at which the appliance may be operated in order to achieve full cooling capacity. The climate rating for the appliance is shown on the type plate.

IMPORTANT Do not operate the appliance outside the specified ambient temperature range. The appliance's refrigerant circuit has been tested for leaks.

General description

ECBN 5066

The appliance is available with the door hinged on the right or left. The door hinges can be reversed on both versions. The door hinge conversion kit is required for this purpose (see section entitled Accessories).

Water connection for IceMaker

A water supply line with a water shut-off valve and an R 3/4 connector is required for the IceMaker.

IMPORTANT The water shut-off valve must not be situated behind the appliance and must be easily accessible to disconnect the appliance from the water supply if necessary.

The water pressure must be between 1.5 and 6 bar. If the water filter is inserted in the appliance, the water pressure must be between 3 and 6 bar.

Diagram: Illustration showing water pressure measurement with a filter.

If the water pressure with the inserted water filter is too low, this may cause the IceMaker to malfunction.

Only use the supply hose provided with the appliance to connect the IceMaker to the water supply.

Diagram: Illustration of the supply hose.

The supply hose is to be connected to the bottom right of the appliance plinth at the front and routed to the rear.

If the hose is routed to the rear left to the water shut-off valve, there is a spare length of 1.6 m of hose.

If the hose is routed to the rear right to the water shut-off valve, there is a spare length of 2.3 m of hose.

Diagram: Depiction of hose routing with spare lengths.

Safety instructions

• The connection to the mains water supply may only be made by trained personnel.
• The water quality must comply with the drinking water directives of the country in which the appliance is used.
• The IceMaker is designed exclusively to make ice cubes in quantities required by a household and may only be operated with drinking water.
• The manufacturer cannot accept liability for damage caused by a faulty connection to the mains water supply.
