• the kettle is horizontal in its upright position. Note: kettle does not heat if it is tilted.
• the mixing tool and mixing tool side attachments are correctly locked in place (both
locking handles must be turned down).

• The lid moves up and down freely and is held in place when fully open

Quarterly maintenance
Quarterly maintenance can be done by anyone, if the kettle has (optional) water filter installed
in the incoming water line. Note chemical safety.
• Perform daily start-up inspection
• Perform decalcification and flushing the steam generator, instructions on next page.
• It is the responsibility of the user to check the safety valve every three months, or have it
checked by qualified personnel.
Scheduled maintenance
Once a year or after 500 used hours
Maintenance and repairs should only be performed by qualified service personnel.
• Scheduled maintenance needs to be done after every 500 used hours or once a year.
Kettle is a pressure device, so even though the used hours (after last service) is under 500,
the kettle needs to be serviced every year.
• The water filter cartridge must be changed every year even if it looks clean (to avoid bac-
teria growth)!
• Depending on water hardness descaling needs to performed with scheduled maintenance
