Installation
Layout dimensions to establish centers and proper clearences,
see dimensional drawings on fold-out page I.
The dimensional drawing and the drilling template for fitting
plate (A) (not included in the scope of deliver) show a form of
installation suggested by GROHE, for which no further
components are required, see fold-out page I.
For deviation to the suggested installation, observe minimum
clearance required for escutcheon sizes.
Prepare fitting plate (A).
Install thermostat unit, see Figs. [1], [2] and [3].
1. Fasten mounting plate (B) to fitting plate (A) centrally, from
below using screws (C), see Fig. [1].
2. Attach pre-mounted thermostat unit (D) to the fitting plate
from above using bolts (E), see Fig. [2].
3. Secure 2 diagonally-opposed screws (E) from below using
cap nuts (F).
By loosening the screws (E), the thermostat unit can be
moved to the right and to the left, in order to enable opening
and closing of the isolating valves following installation or for
maintenance purposes.
4. Connect hoses (G) with G1/2 to the thermostat unit.
5. Attach sleeve (H), see Fig. [3].
