Do not use acidic or abrasive cleaning materials.
8.3

Maintenance for the customer

• If required, unscrew the shower head or outlet pipe and descale with
a commercially available descaler or household vinegar.
• Only pressure-resistant operation: The safety valve must be operated
regularly to verify its function and to descale the valve.
• When the water flows out of the hot water tap much more slowly with
the tap fully open, this is an indication that the appliance requires
dechalking. Call a specialist immediately otherwise the water heater
could be subjected to high pressures.
