3.0 Machine overview
3.1. Description
Geovent CERA arm provides a non-contact and efficient
exhaust gas extraction.
The arm is mounted in a Channal Duct and can be mo-
ved across or along the workshop.
The arm can be rotated 360 degrees and adjusted in
several joints so that it can be positioned precisely in
relation to the exhaust pipe of the car.
When mounting the channel duct take into consideration
that the arm must be able to reach the exhaust pipe of
small cars.
See also Channal Duct data sheet for more options and
details.
3.2 Intended use
Geovent CERA arm is used to extract exhaust fumes
from cars when they are switched on indoors. It can e.g.
be when the car is in a workshop.
The product is not to be used in areas categorised as
ATEX zones, e.g. with dust from aluminium, flour, wood,
and other mediums that present an explosion hazard.

afterwards in a Geovent channel duct.
5.2 Installation
The CERA arm is delivered partly assembled, and con-
sists of 1 pc. partially assembled arm, 1 pc. handle, 1
pc. nozzle and 1 set of hose with clamps. Specification
of any adjustments appear from order confirmation / in-
voice.
The following installation should only be carried out by
a skilled fitter.
Before mounting, please consider the following:
• Space requirements for the satisfactory installation and
service of the Channel Duct System.
• Optimum connection possibilities for piping and auto-
matics.
Recommended installation height
(Adjusted to the length of the Cera-arm)
For installation of the channel duct: See the channel
duct manual.

Procedure:
The aluminum profile of the arm must be loosened.
Loosen the M6 bolt with your fingers.
The M6 bolt is removed and the arm is held so that the
the knee joint and arm are is flush. Then mount the bolt.
2 x M10 fork wrench is used to tighten the joint.
On the trolley there are 4 pcs. M8 x 20 bolts and discs
must be removed, so that the flange of the CERA arm
can be mounted.
Place the flange on the trolle.
Fix the flange with the 4 pcs. M8 x 20 bolts and friction
discs. Then mount the trolley on the channel duct (See
manual for channel duct)
Mount the CERA arm on to the support bracket.

Pull the hose and clamp on to the flange and tighten it.
Mount the nozzle with M6 x 25 insex screws with was-
her. Use a size 5 Allen key.
The hose is mounted on the nozzle and the clamp is put
on and tightened with a 7mm bitz.
The nozzle is now fully assembled.
5.3 Control and test of the security system
Check that the trolley can operated in the channel duct
without any problems. Always pull it with the following
string with handle.
We also recommend checking if the fan is supplying the
volume of air, for which the system has been dimensi-
oned. If the pressure is not sufficient, then the risk of
the hose melting is increased, and if the pressure is too
high, then the trolley will be sluggish to move.
6.0 Commissioning
The trolley with the CERA arm is often moved by the
operator. To ensure the longest possible life time of the
system, the trolley must always be moved / pulled by the
cord with handle, which is mounted on the hose trolley,
as shown on the drawing below. If this is not complied
with, the life of the system will be substantially reduced.
The nozzle is adjusted by using the 2 handles mounted
on it, as shown in the photo below.
The Channel Duct System will not work according to the
intentions if …
• Unauthorised parts are mounted on the rail system, the
Trolley, the hose or on the nozzle.
• The rail system is used for other purposes than for
which it was originally intended.
• The fan is not switched on – the hose will melt!
Under normal conditions the arm is able to carry itself
in the position within the working area. The arm bracket
gives the arm a 360° working area.
The hose can be damaged and made leaky by external
load from e.g. a screwdriver. This should therefore be
avoided to ensure the longest possible life of the hose.

The nozzle should be placed directly in front of or close
to the exhaust pipe. Right over the source of pollution.
This captures up to 99% of the contaminated particles.
Always check that the correct amount of air is extracted
at the nozzle.
7.0 Control, test and maintenance
Check the installation according to chapter 5.3.
7.1 Control
Check the installation according to chapter 5.3.
7.2 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 neces-
sary. Please contact your dealer in respect of spare
parts.
At least once annually, the system should be overhauled
by an authorised serviceman.
8.0 Cleaning
The outside of the product is cleaned with a vacuum
cleaner or a cloth.
9.0 Troubleshooting
In case of problems with the CERA arm, the following
points can be reviewed:
Problems with the hose
• The hose melts near the nozzle. This happens if there
is not enough suction on the system, or if the hose
bends near the nozzle. Can be fixed by increasing the
air volume or by replacing the hose near the nozzle
with high temperature hose.
10.0 Dismantling, disabling and scrapping
Deactive the product by disconnection the electrical
mains. Dismantle compressed air pipes and other pipes
or wires etc.
The inside of the product must be cleaned by means of
a vacuum cleaner with a fi lter which suits the purpose.
Dismantle plastic parts and dispose of it according to
local regulations.
Dismantle the metallic parts by unscrewing screws and
bolts. Afterwards cut the larger pieces into smaller pie-
ces and dispose of it according to local regulation.
Dismantle plastic parts and dispose of it according to
local regulations.
The packing material must be sorted according to local
regulation in order to be able to reuse the material.
