4.5 Installing the Pinch Valves
In order to prevent damage during transport, the following parts
-pinch valves (15)
-suction pipe (16)
-holder (20)
are not mounted on the device, but will be delivered in a
pre-assembled state.
⇒
These must be installed onto the device before use:
⇒
Unscrew the knurled head screw (19, Fig. 4a).
⇒
Push the suction pipe (16) onto the suction support on the
extractor and hang the holder (20) onto the holder screws
(26, Fig. 4b).
⇒
Fix the holder in place with the knurled head screw
(19, Fig. 4a).
⇒
Connect the compressed air tubes to the pinch valves:
-Ensure the compressed air tubes (A, B) are connected to the correlating suction pipes (A, B).
-Push the compressed air tube onto the pipe connection in the pinch valve as far as it will go.
There will be a slight resistance to overcome when attaching.
4.5.1 Suction Pipe Alteration
During the alteration, make sure that the compressed air tube is not unintentionally ripped
away from the pinch valves. If possible, loosen before the alteration (press the ring at the
compressed air connection and pull the tube towards you) and tighten again after the work has
finished.
⇒
Pull the pinch valves (15, Fig. 3) out of the suction pipe (16, Fig. 3).
⇒
Unscrew the knurled head screw (19).
⇒
Loosen the suction pipe and the holder (20) from the holding screws (26) by
turning and then at the back, remove from the extractor connection fitting (A).
⇒
Lever the suction pipe out of the holder (B), turn (C), and replace back into a
new position in the holder (D).
⇒
Insert the suction pipe into the extractor connection fitting on the extraction de
-
vice, hang (E) the holder into the holding screws (26).
⇒
Fix the holder with the knurled head screw (19).
⇒
Push the pinch valve into the suction pipe as far as it will go.
This process is made easier by turning slightly when pushing into place.
4.6 Connection to the Extraction Point
The extraction point is at the extractor connection fitting (15).
When you turn the pinch valve, please ensure that there are no kinks in the compressed air
tubes and that they are not unintentionally ripped off!
The compressed air tubes are marked with A and B so that they can
be easily allocated to the relevant suction hoses.
⇒
Shorten the suction pipes for both extraction points to the required
length with a knife.
⇒
Screw the PVC end bushings onto the suction pipes (left handed
thread).
Caution: Risk of injury!
When shortening the suction pipe please ensure to cut at a right
angle.
⇒
Insert the suction hose (18) into the extractor connection fitting (15).
Please use a hose connection adapter (see accessories) if the diameter sizes are different, in order
to minimize ambient noise and loss of extraction force.
⇒
Attach the suction hose to the extraction point (e.g. Dustex master plus, extractor clamp, etc.).
