Applications
The radio receiver unit triggers flushing by using a radio
transmitter.
Additionally, flushing can be triggered by manual actuation.
Manual actuation requires a WC cover plate for the pneumatic
outlet valve (not included in the delivery specification).
For actuation via radio control, use radio transmitter order
no. 38 758 or 39 142 + button (see replacement parts fold-out
page I). As an alternative to GROHE radio transmitters, the
product can also be used with radio transmitters made by
Hewi, Keuco, Lehnen, Normbau, Pressalit, AMS, Deubad,
Erlau FRELU and FSB.
Installation is an option with cistern GD2 with pneumatic outlet
valve and filler valve on the left side, see fold-out page I
Fig. [1].
