Lennox Hearth F50 manual De-scaling

18. De-scaling

Your IMPRESSA features an integrated de-scaling program. The de-scaling operation will take some 40 min.

JURA de-scaling tablets wich are specially designed for the de-scaling program of your IMPRESSA are available at your authorized dealer. Please note that machine defects or residues in the water cannot be excluded if you use inappro- priate de-scaling solvents.

If the IMPRESSA needs de-scaling, the corresponding mes- sage is displayed.

You can still draw off coffee or hot water/steam and start the de-scaling program later.

Before starting the de-scaling program, the machine must be switched off. Once started, the de-scaling operation must not be interrupted.

When using the de-scaling solvent, immediately remove any splashes or drips from sensitive surfaces, i.e. natural stone and wooden surfaces, or take appropriate precautions.

In any case wait until the de-scaling solvent is used up and the tank is empty. Never refill de-scaling solvent.
