Installation and commissioning

Flush pipes thoroughly before and after installation
(observe EN 806)!
Adjust bypass of filterhead according to local carbonate
hardness and connect filter cartridge.
The carbonate hardness can be tested by using the enclosed test
strip or the relevant water supplier can provide information on the
carbonate hardness.
Note: The volume of water in the storage heater will expand as
it is heated. The expansion water must drip out of the funnel of
the safety assembly.
This is a necessary and completely normal process.
Check all connections for leakage.
Retighten screw connections as necessary.
Control:
The control is set for operation with the S-size filter cartridge
(prod no.: 40 404 001) at the factory.
The control must be adjusted for operation with other filter
cartridges, see page 7.

Maintenance and cleaning

CAUTION!
Risk of damage!
Always disconnect from the voltage supply before
carrying out maintenance work on the system. The plug-in
connector can then be disconnected.
If work is performed on mains power supply or in case of
any maintenance work, the GROHE Red boiling system
must be bled as otherwise blasts of steam could form as a
result.
• Draw off boiling water from the storage heater until just cold water
flows.
• Close the service valve, switch off the storage heater and
disconnect the mains plug.
• Open the lever on the fitting and as well as the rotary knob on the
safety assembly to depressurise the storage heater.
• Drain the storage heater (not required each time maintenance is
performed): Remove the cap or hose to the mixing valve and
drain the storage heater using the connecting hose to the safety
assembly.
• Inspect and clean all parts, replace as necessary and lubricate
with special fitting grease.
