INSTALLATION, OPERATION & MAINTENANCE
(continued)
Using Your VentBoss Fume Arm
The construction guarantees a safe and reliable function without continuous servicing and
special handling. The adjustment of the ERGO extraction arm consists mainly in corrections
within the frictional joints. The frictional brakes are placed in each joint of the d evice and
their function is to give the balance and self-supporting properties of the whole extraction
arm and ensure an easy manoeuvring during the operation.
The adjustment of the frictional brakes is carried out by increasing or reducing the tension of
the nuts upon the frictional elements.
The brake adjustment in the following joints ought to be executed in such a way that it
guarantees the stability and self-supporting features of the extraction arm (which is important
to keep the stable arm position), whereas on the other hand this cannot cause any excessive
resistance while User is changing the arm position. Having completed the adjustment, tighten
up the counter-nut. The placement of the adjustment nuts is illustrated in the “VentBoss
Extraction Arms – Dimensional Drawings” (Diagram 1—Appendix A).
Safety
The VentBoss extraction arms will not cause any risk provided that they are firmly and
correctly mounted to the wall or another structural element of the building.
CAUTION! Unsure installing could cause uncontrolled detachment
of the device and be serious risk to personnel / people in the vicinity.
Having completed the work, leave the extraction arm in the ultimate operational position, in
case when it constitutes obstacle to personnel/User, set in into the home position.
Prior to installing check the load carrying capacity of the building structure.
Type
1. The extraction arm is falling.
2. The extraction arm is
automatically setting always
in the same position.
3. Drop in the air suction rate
along with the increased
noise level.
Possible Reason & Corrective Action
-Improperly adjusted frictional brake.
-Increase the tension upon frictional disks of the brake
in the joint by tightening the adjustment nuts.
-The rotation axis of the arm is not positioned vertically.
-Carry out the positioning of the mounting flange of the
ERGO extraction arm to set the rotation axis vertically.
-Improper impeller rotation sense of the extraction fan.
-Change the phase connection sequence (only 3-phase
motor). If the mesh holes of the inlet net are clogged,
clean them using a wire brush.
