During decalcification, you must also observe the following
•
Damage to the appliance if decalcification is interrupted.
- You must complete the decalcification process and then rinse thoroughly with clean water.
- Allow about 3 hours for decalcification. The appliance works on its own for most of this time.
•
Sensitive surfaces (e. g. marble) may be damaged through contact with the decalcification agent.
- Immediately remove splashes of decalcification
a) Preparing for decalcification
For safety reasons, once the decalcification 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 decalcification 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 decalcification in progress” in a clearly visible position. Warn
-
ing signs are enclosed with the decalcification tablets.
b) Draining the water system
Tasks outside the RV
• Remove the access door (refer to “Removing the access door” on page 52).
• Switch OFF the appliance at the POWER switch.
• Drain the water system and remove the water inlet filter. To do this, refer to “Draining the water and cleaning the
water inlet filter” on page 60, Steps 4 to 8.
You must use the water inlet filter for decalcification (included with the delivery Fig. 1 – 11a). If you are using an elec
-
tric antifreeze kit, it must be removed and be unplugged from the power supply before decalcification (see Fig. 11).
