4.3 Checking the circulation units
When starting up for the fi rst time and at least once a year, it is
advisable to check that the shaft of the circulation units rotate.
This is necessary because, especially after lengthy periods of in-
activity, deposits and/or residue may stop it rotating freely.
Releasing the circulation unit shaft if necessary
To release the shaft, proceed as follows:
− insert a screwdriver (Phillips no.2) into the hole (1) of the
circulation unit
− press (a) and turn (b) the screwdriver until the motor
shaft releases
