What To Do If The Pipe System Or The Exhaust Pipe Is Blocked; Details Required For Maintenance Purposes - Allaway V3 Bedienungs- Und Wartungsanleitung

5.4 What to Do if the Pipe System or the Exhaust Pipe Is Blocked

 Empty the dust canister and clean [replace] the filter.
 Locate the blockage by sucking strips of kitchen paper through the wall inlets. If the strips of paper
end up in the dust canister, that stretch of the pipe system is clear.
Once you have located the blockage, disconnect the central unit and check that there are no blockages

in the coupling hoses. Then use the suction hose bushing to connect the suction-side coupling to a
wall inlet along the blocked stretch [or to the wall inlet closest to the blockage, if the blockage is
in the frame pipe]. Start the central unit via the low voltage connector [figure 1;7] with the help of
a piece of metal wire, and then go to where the central unit is usually mounted. Block and unblock
the suction pipe opening with your hand to send vacuum shocks to the blocked pipe. If the blockage
has not become dislodged within 10-15 seconds, disconnect the central unit from the wall inlet to
allow the turbine to get some air in between and to stop it from overheating. Repeat the process
after approximately one minute.
 If the blockage cannot be dislodged through suction and you are able to pinpoint its location, it is
worth examining whether the pipe system is easily accessible without having to dismantle too much
of the structure. If the pipe system is accessible, the blockage can usually be removed by opening a
pipe joint.
Never use overpressure, such as compressed air, to try unblocking the pipe system, as overpressure

will cause the pipe joints to become undone.
 You can also try dislodging the blockage by inserting a tension spring into the pipe system, taking
care not to damage the pipe joints.
 If none of the measures described above are successful in unblocking the pipe system, contact an
authorised Allaway service dealer.

5.5 Details Required for Maintenance Purposes

Prior to contacting an authorised Allaway service dealer, note
down the type and serial number [N:o] of your central unit,
marked on the nameplate [on the external surface of the central
unit, on the side of the turbine housing].
Always keep the unit in its normal upright position during
transportation and take care not to drop it or to make it subject
to blows.
