– Position the tap lever so that the blast air and pipe system are connected (B-C
connection).
The connection to the FAS-420 must be blocked for blowing-out!
Manually blow out the pipe system for approximately 10 seconds.
– Set the lever of the tap such that the device is not connected with the pipe system or
with the connection for the blast or compressed air supply. Wait approximately 20
seconds so that dust and dirt raised in the pipe system can settle and thus will not be
sucked through the aspirating smoke detector.
– Reconnect the blown-out pipe system to the FAS-420 within a further 10seconds by
switching over the tap accordingly (A‑C connection).
