3. Appliance description

Observation of these instructions and of instructions for any ac-

cessories used is also part of the correct use of this appliance.

The closed (pressure-tested) appliance heats DHW electrically.

You can adjust the temperature using the temperature selector.

Subject to the power supply, the water is heated automatically to

the required temperature.

The internal steel cylinder is coated with special "Co Pro" enamel

and is equipped with a protective anode. The anode protects the

internal cylinder from corrosion.

Frost protection

The appliance is also protected against frost by the temperature

setting "*", provided that the power supply is guaranteed. The

appliance switches on in good time and heats the water. The ap-

pliance does not protect the water supply lines and the safety

valve from frost.

 Never use abrasive or corrosive cleaning agents. A damp

cloth is sufficient for cleaning the appliance.

Scaling

 Almost every type of water will deposit lime at high temper-

atures. This settles inside the appliance and affects both the

performance and service life. The heating elements must

therefore be descaled from time to time. A qualified contrac-
