4.1.5. Yearly
• It is advisable to have the unit checked once a year by qualifi ed personnel. Preventive checking is the
best guarantee for operational reliability and saves breakdown costs.
• Depending on the hardness of water, descaling must be done by qualifi ed personnel. If the kettle is
equipped with the cooling function and it has been used often descaling should be done more than
once a year. When doing the fi rst descaling the technician can estimate when the following descaling
must be done.
Fill out the form “Notes on service work” with information on service work which has been done accord-
ing to the instructions. Maintenance work ensures the safe and reliable function of the kettle.
