GROHE recommends that the fitting be fitted in combination
with the lower part 29 037, available in the GROHE product
range.
Fitting and connection, see fold-out page II, Figs. [1] to [9].
Refer to the dimensional drawing on fold-out page I.
Flush pipes thoroughly before and after installation
(observe EN 806).
Shut off cold and hot water supply.
I. Install the operating unit, see fold-out page II, Fig. [1].
II. Install the spout, see Figs. [2].
III. Install the diverter, see Fig. [3].
When screwing in (left-hand thread) the sleeve (A), make sure
that the internal groove aligns with the position of the set
screw (B).
IV.Install the hose guide and hand shower, see Fig. [4].
V. Install the hoses, see Figs. [5], [6] and [7].

Connection to the supply line
Installation with lower part (29 037), see Fig. [8].
1. Fit enclosed hoses (E) to hoses (G) of the lower part.
2. Connect hoses (E) to pipes (D).
Open cold and hot water supply and check that
connections are watertight.
Fasten prepared wall plate (F) to the tile shelf or bath edge
with set (F1) of the lower part, see Fig. [8].

In this way, the inspection chamber will be accessible at any
time.
Installation without lower part, see Fig. [9].
1. Connect enclosed hoses (E) to the existing connections.
2. Fit hoses (E) to pipes (D).
Open cold and hot water supply and check that
connections are watertight.
Install plate on tile shelf or bath edge.
Grout the joint around the wall plate with a permanently
elastic material.
In this way, the inspection chamber will be accessible at any
max. 10 bar
time.
16 bar
Operation

The preassembled temperature limiter is not active in delivery
condition.
Maintenance
Inspect and clean all parts, replace as necessary and lubricate
with special grease.
