2 Safety
2.1 Classification of important informa-
tion
This document contains important information that
is presented either as a warning, caution or note, ac-
cording to the following examples:
WARNING! Risk of personal injury
Warnings indicate a potential hazard to the
health and safety of personnel, and how that
hazard may be avoided.
CAUTION! Risk of equipment damage
Cautions indicate a potential hazard to the
product but not to personnel, and how that
hazard may be avoided.
NOTE!
Notes contain other information that is import-
ant for personnel.
2.2 General
• Transport the FlexFilter to the installation place
while still in its factory packing. FlexFilter with legs,
which is the most common model, should be trans-
ported to the installation place still bolted to its pal-
let in order to prevent it from overturning during
transport.
• The FlexFilter should be anchored to a hard, level
and firm foundation.
WARNING! Risk of fire
Burning or glowing material must not be
sucked into the FlexFilter. A glowing cigarette
can start a fire in the collected material or in
the filter socks. Sparks from welding or metal
grinding are not normally a problem as they are
extinguished in the vacuum hose. FlexFilter is
designed for the fitting of an optional thermal
fuse that breaks a control circuit stopping the
vacuum unit should the temperature rise too
far.
NOTE!
For plasma cutting and other processes creat-
ing a great deal of hot material, a suitable pre-
separator should be installed.
• Standard supply voltage for control units and ac-
cessories is 24 V DC. Specially designed control units
and FlexFilter, with a supply voltage higher than 24
V AC/DC, must be grounded. Since the touchable
metal surface area is large, earthing is recommen-
ded also for 24 V installations. Earthing also helps in
reducing the build-up of static electricity.
• Static electricity frequently occurs in dust collectors.
FlexFilter modules have rubber sealing rings con-
ducting electricity. Therefore, earthing of just one
of the modules is sufficient in most cases. In some
cases, grounding of the piping system is also recom-
mended.
• Compressed air pressure must not exceed 1 MPa (10
bar, 145 PSI). Normal working pressure is 0.6–0.7
MPa (6–7 bar, 85–100 PSI).
• FlexFilter has a low noise level (well below 70 dBA)
during normal operation. During filter cleaning,
which normally takes 2–4 seconds every second
hour, the resultant noise may cause a nuisance in
the immediate vicinity of the FlexFilter. In a few
cases, noise-damping baffles may be required.
WARNING! Risk of personal injury
Read the Safety section for special modules
that may be installed with the FlexFilter. In-
correct installation or handling of modules 7D
and 7H, see
Figure 1 , can cause severe injury or
even death.
CAUTION! Risk of equipment damage
If FlexFilter has been dismantled, ensure that
the rubber sealing rings and the steel retain-
er rings, keeping the modules together, are
correctly re-assembled. A badly fitted retainer
ring could, at worst, cause the FlexFilterto fall
apart.
