Grohe Red Duo 30 083 Mode D'emploi page 8

Installation
Refer to the dimensional drawing on fold-out page I.
Installing fitting, see fold-out page II, Figs. [1] and [2].
Insert fitting in sink hole. This will require leading through the
hoses one at a time.
Note: If there is no need to fit support plate (A), the clamping
length may be increased by 15mm, see Fig. [1].
Connect the T-piece (B) provided to the drainage pipe,
see Fig. [3].
Connect the funnel (C) to the discharge, see Fig. [3].
Install safety assembly (D) on funnel (C), see Fig. [4].
Install storage heater taking into consideration the
available hose lengths, see Figs. [2] and [5].
Do not connect voltage supply yet.
Flush pipes thoroughly before and after installation
(observe EN 806).
Connect safety assembly (D), see Figs. [2], [4] and [5].
1. Install adapter (E) on the cold-water service valve, see
Fig. [5].
2. Screw hose (F) to safety assembly (D) using the seals
provided and connect to adapter (E).
3. Secure storage heater pressure hose (G) marked blue to
safety assembly (D) using the seals provided.
To prevent overpressure, the outlet valve (D2) of the
safety assembly must not be covered, see Fig. [4].
Connecting fitting, see Figs. [2] and [5].
1. Screw fitting pressure hose (H) marked blue to adapter (E),
see Fig. [5].
2. Screw red marked pressure hose (J) of the fitting onto the
hot-water service valve.
3. Connect the fitting pressure hose (K) marked 100 °C to
connection (K1) on the storage heater.
Open the service valve and check connections for
watertightness.
Filling storage heater with water, see Figs. [4], [6] and [7].
1. Open shut-off valve (D1) at safety assembly (D), see detail,
Fig. [4].
2. Pull button (L1) on handle (L) of fitting outward and turn the
handle anti-clockwise, see Fig. [6].
3. Fill the storage heater until water comes out the spout of
the fitting.
4. Connect voltage supply via mains plug (M), see Fig. [7].
5. Press and hold button (N) on storage heater for at
least 2 seconds to switch on the storage heater. The red
indicator lamp (N1) indicates that the storage heater is
switched on.
Important note
The volume of water in the storage heater will expand as it
is heated. The expansion water must drip out at funnel (C)
of safety assembly (D), see Fig. [4].
This process is necessary and normal.
5
The spout must not be fitted with any downstream
resistances in the form of air bubblers (e.g. mousseurs) or
components reducing flow (e.g. restrictors) as these will
result in damage to the storage heater.
The GROHE Red boiling water system is now fully
installed and ready for operation.
The date of installation must be noted on the
maintenance sticker and affixed at a visible location
on the storage heater.
Operating the fitting
Note:
In order to prevent incorrect operation and for protection
against injury, we recommend affixing the sticker provided.
Open lever (O) to draw water, see Fig. [8].
Pull button (L1) on handle (L) outward and turn and hold
handle (L) anti-clockwise to draw boiling water. Handle (L)
closes automatically.
Press and hold button (N) for at least 2 seconds to switch the
storage heater on or off, see Fig. [7].
Maintenance
In the case of interventions in the mains supply
or maintenance work, the GROHE Red boiling
system must be bled as steam jets could
otherwise occur.
Close the service valve, switch off the storage heater and
disconnect the mains plug.
Wait until the storage heater and fitting have cooled down.
Open the lever to depressurise the storage heater.
Inspect and clean all parts, replace as necessary and lubricate
with special grease.
I. Cartridge (P), see fold-out page II, Fig. [9].
1. Lever out plug (R) and remove set screw (S).
2. Remove lever (O) and cap (T).
3. Remove screw coupling (U) and take out cartridge (P).
Assemble in reverse order.
When installing the cartridge (P), ensure that the seals are
correctly seated. Screw in screw coupling (U) and tighten.
II. Mousseur
Remove and clean mousseur (13 263), see fold-out page I.
Assemble in reverse order.
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.
