1.0 General safety precautions
IMPORTANT – Please study all the instructions before
mounting and commissioning.
Please keep these instructions in a safe place and in-
struct all users in the function and operation of the pro-
duct.
All electrical installations must be carried out by an
authorized electrician.
1.1 Danger
It may be associated with clamping hazard of ngers /
hand if the arm is folded together by grip around the arm.
1.2 Field of application
The GEOVENT MINI Arm is the ideal extraction arm for
the extraction of fumes and vapors etc., where the well-
being of the operator is in focus with regard to lightness,
ergonomics and e󰀩ciency of the Arm.
The extraction arm is as standard not suitable for the
extraction of aluminum dust, our, textile dust nor saw-
dust or other media, which are connected with danger of
explosion, without specic approval from Geovent A/S.
For ATEX application, the ATEX upgrade must be ap-
plied (See point 1,4 and 2.1).
The hose may be damaged and leaky via outer loads,
e.g. by a screw driver. Avoid such load in order to safe-
guard a long life.

is easy to rotate, however, still so much that it is self-
retentive in a lightly bent position.
6. The hose is mounted on the funnel by tightening the
clamp around the funnel and the hose.
7. The hose is xed to the arm by a small white plastic
holder. It is to be xed in the middle of each arm sec-
tion, by means of the self cuttings screws, through the
ALU prole.
8. Slide the strips through, and xe the hose accordingly,
so that you have enough room to maneuver the arm
freely.
2. The arm comes pre-assemble, but in case adjust-
ments needs to be made, please follow the following
steps.
3. Mount the arm on the wall bracket/console with the
bolt and bushings, arm part, discs and nuts. Make
sure to fasten it in such way that the arm is easily ro-
tated. If the inner joint/arm does not have the wanted
friction, the bell washer can be loosen or tighten.
4. Mount the centre part by taking the supplied bolt th-
rough 3 disc springs, the alu prole, the friction disc,
the other alu prole and 3 disc springs and fasten
them with a lock nut. Tighten the joint so that the arm
5. Mount the funnel on the outer joint by taking the sup-
plied M8 bolt through 3 disc springs, the alu half, the
friction disc, the other alu half and the 3 disc springs
and fasten them with an M8 lock nut.
2.0 Installation
The MINI Arm is supplied partly assembled. Depending
on model, it may consist of 1 partly assembled carrying
arm, 1 funnel and 1 set of hose with clamp.
Specication of any changes can be found in order con-
rmation / invoice.
Before mounting, consider the following:
• Su󰀩cient space for satisfactory use of the arm.
• Optimal installation height for the task
• Connection options for piping and possibly. automation
Procedure:
1. The wall bracket is rmly attached to the wall, ceiling
or table by means of 4 bolts.
IMPORTANT – see pictures below
Wall mounted – VERTICAL
Table or Ceiling mounted - HORIZONTAL

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 nal 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 xed 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.
Optimal situation:
Less optimal situation:

Always check that the correct volume of air is extracted
by the suction head/funnel.
The Arm does not work if …
- unauthorised parts have been mounted on the arm
(e.g. power point on the funnel)
- The arm is pushed towards the required position. In-
stead, please move the arm to the required position
and wait a moment until the friction discs have locked
the arm. If this does not work, please tighten the loose
joint with two 13 mm xed spanners.
- Something has been hung on the extension arm. It is
only meant to be capable of carrying the weight of the
actual arm.
4.0 Maintenance
Periodic maintenance
- When it becomes di󰀩cult to position the arm, e.g. if it
will not remain in the required position, please adjust
the movable joints (please refer to item 2).
- Please check the condition of the hose, as well as the
friction discs, and exchange them if necessary. Please
contact your dealer in respect of spare parts.
At least once annually, the whole point extraction plant
should be overhauled by an authorized serviceman.
