have an angle of at least 3% towards the neutraliser
or the drain.

The Sime ESTELLE HE B4 INOX ErP boiler requires the connec-
tions shown below, which must be carried out by the installer or
by professionally qualified personnel.
To connect the electrics:
– remove the front panel (1) to access the control panel
– loosen the screws (2) that fasten the control unit cover (3).
– turn the cover (3) downwards to access the internal terminal
block (MIQ).
The cables must enter from the rear of the boiler and must then
be locked, once the job has been completed, with the tear-proof
cable clip already fitted. Once the connections have been made,
reassemble the previously dismantled elements.
