Replacement Parts - Grohe Red Duo 30 079 Manual De Instrucciones

III. Safety assembly
The GROHE Red boiling water storage heater includes
a safety assembly. The safety assembly (D) provides a way of
checking whether the expansion water is flowing unobstructed
from the storage heater via the funnel (C), see Fig. [4].
The expansion water drips out as the water is being heated.
The outlet valve (D2) must be actuated twice a year to check
whether it is blocked. To do this, carefully open the outlet
valve (D2) briefly in an anti-clockwise direction until water
escapes at the funnel.
