Replacing the solenoid valve / the flow regulator with replacement fine filter
NOTICE!
The flow regulator is already included in a spare part solenoid valve type
14 l/min suitable for concentration settings of 0.25 - 3 % and does not need
to be replaced in this case. For concentration settings of 3.5 - 5 % (even
with a new solenoid valve), the flow controller must be exchanged for the
10 l/min. type.

NOTICE!
It is essential to ensure the correct installation position of the new flow
regulator. The plane (flat) surface of the flow regulator (4a) is to be
aligned in the direction of the water inlet as shown in the illustration.
6.
Replace the fine sieve:
n Unscrew the screw cap (pos. 6) with the strainer insert (pos. 5).
n Pull off the strainer insert and clean or replace it.
Installation: To be able to guarantee the tightness, insert the fine
sieve (pos. 5) into the screw cap (pos. 6) and then install both into the
solenoid valve (pos. A).
7.
Reinstall the solenoid valve in reverse order.
NOTICE!
Use a new flat gasket and make sure it is seated correctly.
8.
Reconnect the electricity and water supply.
9.
Check that the device is functioning properly and make sure that it is not leaking.
