2.1 Installation - ATEX application
This is only necessary, when the ATEX upgrade packa-
ge has been purchased.
The mini arm is based on the same components as the
standard version, but there are some small alterations
that needs to be followed correctly.
1) The hose that is applied is the transparent hose (P2
PU AS).
2) The wire on the hose, is to be freed from the hose
construction, so that you have app. 10-15 cm of wire,
that can be moved around.
3) Connect the loose end of the wire, as shown below.
4) Connect the other end of the hose to ground, in order
to make the arm antistatic (R8 <10 Ohm).
2.2 Mounting of optional equipment
Installation of damper
The MINI arm can be supplied with a damper. The dam-
per must be installed from the factory. Contact your de -
aler.
2.2 Trial run – exact adjustment
After the final mounting, the MINI Arm should be adju -
sted to the typical working area, for optimum utilization
of the arm. Do so by adjusting the rotary joints mentio -
ned in item 2 by means of 2 fixed spanners.
If there is a problem with the arms carrying ability, you
can try to add more plate springs (black) to the joint, so
that the arm can be tighten further.
The following guide gives you an idea about how tight
each joint should be. Please note, this is only a guide,
and may vary according to the actual installation and
personal preferences.

3.0 User instruction – application
For normal use, the arm is to be self-retentive in the re-
quired position within the working area. The bracket of
the arm supplies a 360° rotary working area.
When moving the arm, remember to hold it in the requi-
red position for app. ½-1 second, so that the joint will
lock up in the requested position (do not push the arm
into position).
If the equipment has been correctly dimensioned, the
funnel of the arm should be placed in vertical position
300-500 mm over the point of pollution.
Thus up to 99% of the polluting particles will be caught.
