Maintenance
The kettle needs careful maintenance for maximum reliability. Essential maintenance which must be car-
ried out by the owner/user of the machine is described below. Failure to follow these instructions will re-
lease the manufacturer from any liability.
CAUTION!
During the heating process, steam pressure is generated inside the jacket and it is therefore im-
portant to exercise caution when maintaining the appliance. This can be ensured by following the
instructions in this section and by only using suitably trained service technicians for servicing
the kettle.
Monthly maintenance
NOTICE!
This maintenance can be undertaken by the daily user.
CAUTION!
Take care to avoid discharging steam when the safety valve is opened
The safety valve must be operated every month to ensure that it is operating correctly and that it has not
become jammed as a result of lime scale deposits, etc. Check that the pressure inside the kettle is zero
using the kettle’s pressure gauge before opening and closing the safety valve.
Raise handle fully to open the valve. Lower to close the valve.
