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.
Do not dismantle any factory-mounted parts, since it im-
pedes the commissioning of the equipment.
All electrical installations must be carried out by an
authorised electrician.
1.1 Danger
Explosive media – The Extraction Arm is not suitable
for the extraction of aluminium dust, flour, textile dust
nor for sawdust or other media, which are connected
with danger of explosion, without specific approval from
Geovent A/S.
Placing the hand between the gas spring and the carry-
ing arm could involve a risk of mutilation.
Boring in the gas spring or other ways of puncturing it is
deadly dangerous.
1.2 Field of application
The GEOVENT ASA-3 Arm is the ideal Extraction Arm
for the extraction of welding smoke, grinding dust, fu-
mes, etc., where the well-being of the operator is in
focus with regard to lightness, ergonomics and efficien-
cy of the Arm.
The Extraction Arm is not suitable for the extraction of
aluminium dust, flour, textile dust nor sawdust or other
media, which are connected with danger of explosion,
without specific approval from Geovent A/S.
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.
1.3 Handling
Always use gloves when you are handling this product.
Always lift the arm in the aluminum arm during transport
and assembly.
Be aware that it is possible to trap your fingers between
the gas spring and aluminum arm.
A mounted arm is operated exclusively by the hood.

Arms and friction joint: 25x25 mm aluminium pipe,
connected via knee joints with friction discs and disc
springs. The inner reinforced arm is executed in 30x30
mm electro galvanised steel pipe and supplied with a
gas damper.
Hose and pipes: Ethyl-vinyl-acetyl (EVA) hose. Mack
of extruded EVA material. Inside and outside wavy. Is
self-supporting, so a spiral is unnecessary.
2.0 Installation
The ASA-3 Arm is supplied partly assembled. Depen-
ding on model, it may consist of 1 partly assembled car-
rying arm, 1 funnel and 1 set of hose with clamp. The
centre part of the carrying arm is to be turned around
and fastened with two 13 mm fixed spanners.
Before mounting the Arm, please make sure that the op-
timum working area is selected. Is there space enough
for the satisfactory utilisation of the Arm? What about
connection possibilities for piping and automatics? The
optimum installation height is then to be selected in ac-
cordance with the table below:

Recommended installation height HV50 arm: 2500
mm
Procedure:
1. The wall bracket is firmly attached to the wall by
means of 4 off 10 mm bolts. (When using the exten-
sion arm, please fix this bracket first – refer to item
2.1)
2. Mount the Arm on the wall bracket with the M16
bolt and friction discs. Make sure to fasten it in such
way that the Arm is easily rotated. If the inner joint/
arm hasn’t the wanted friction, the bell washer can
be loosen or tighten, or by adjusting the spring re-
tainer (against the wall to tighten – away from the
wall to loosen).
3. Center wrist checked and tightened if needed. Tigh-
ten the joint so that the arm moves freely, but also
so fast that it can sustain itself in a slightly bent
position.
4. Mount the funnel on the outer joint by taking the
supplied 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.
5. The hose is mounted on the funnel by tightening the
clamp around the funnel and the hose. Now pull out
the hose to max. so that the least possible resistan-
ce is left in the hose and fasten with the enclosed
plastic binders. Subsequently, the hose is mounted
on the branch pipe by means of the clamp.
2.1 Mounting of optional equipment
Mounting of extension arm
The extension arm for HV50 is available in 1.0 m, 2.5
m and 4.0 m. (4,0 m available in both 1 and 2 line
arm).
1 m extension
Fixing the extension arm to a solid wall, in the same
way as the wall bracket in the section. 2.0.
Then fastened HV50 arm to the extension arm.
2.5 and 4.0 m extension
Attach the wall bracket.
Then install the extension arm
At 4.0 meters 2-leds mounted inner part, then mid link
and eventually outer loops. Ensure that the outer part
is positioned properly during assembly - tube holders
must face up.
Then attach the ducts to the extension arm with the
self-carving screws. The distane between the duct as-
sembled using a Clamp and the hose. The arm is then
fastened to the extension arm.
2.2 Trial run – exact adjustment
After the final mounting, the Arm should be adjusted to
the typical working area, for optimum utilisation of the
Arm. Do so by adjusting the rotary joints mentioned in
item 2 by means of 2 off 13 mm fixed spanners.
3.0 User instruction – application
Operated by the hood. Do not use the arm or hose.
Be especially aware that it is possible to squeeze your
fingers at the gas spring.
Move the hood to the wanted position and wait for the
friction discs to locked the arm.
In normal use, the arm can lift it self in the wanted positi-
on. The arm can rotary 270oin the working space.
The hose can be damaged and leaky by not using it
right, for example a screwdriver. This should be avoided
to ensure a long life span.
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 fixed 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 difficult 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, the spring as
well as the friction discs, and exchange them if necessa-
ry. Please contact your dealer in respect of spare parts.
At least once annually, the whole point extraction plant
should be overhauled by an authorised serviceman.
