Installing the vacuum sensor
Fix the sensor unit (1) on the wall in an upright position, as shown in the drawing.
Drill an 8 mm hole in the air pipe for the lead-through sleeve Fix the lead-through sleeve using self-tapping screws
(4). Do not forget to place the rubber washer (3) between the pipe and the lead-through sleeve.
Connect the PVC hose to the "upper" connector (5) of the sensor unit; the cover plug of the connector, closest to
the wall, must be removed. Connect the other end of the hose to the lead-through sleeve.
Connect the cable, using the Abico-connectors included in the delivery, to the terminals 2 and 3 (6), as shown in
the wiring diagram.
The pressure is adjusted by means of the disc, located in the centre of the sensor unit. Set the sensor to such a
pressure value, that the positions 2–3 of the change-over contact will be switched on, even if the air adjuster plate
is in its minimum position.
If the change-over switch is not switched on, the oil burner will not start.
