a) Preparing for decalcication
For safety reasons, once the decalcication process has started it must not be stopped until the system has
been rinsed (see process f). All operating modes of the appliance are blocked until decalcication has been
completed.
Tasks within the RV
• Set the control panel to “Off”.
• Turn OFF the water supply or switch OFF the water pump.
• Open a hot water faucet to relieve pressure in the system.
• On all water faucets attach the warning sign “Caution decalcication in progress” in a clearly visible position
Warning signs are enclosed with the decalcication tablets.
b) Draining the water system
Tasks outside the RV
• Remove the access door (refer to “Removing the access door” on page 48).
• Switch OFF the appliance at the POWER switch.
• Drain the water system and remove the water inlet lter. To do this, refer to “Draining the water and cleaning
the water inlet lter” on page 56, Steps 4 to 8.
You must use the water inlet lter for decalcication (included with the delivery
Fig. 1 – 11a). If you are using an electric antifreeze kit, it must be removed and be
unplugged from the power supply before decalcication (see Fig. 11).
