Malfunction Possible Cause Solution
Air ow rate in
the unit is too
low.
The frequency at the potentiometer or
inverter may be at a low level.
Increase the rotational speed of the fan by rotating the potentiometer
in the positive direction or by increasing frequency from the inverter.
Filters may have been lled with dirt
and be causing additional pressure.
Check the pressure loss at lters. If maximum pressure loss has been
reached, replace lters.
Air ducts upstream of the ecology unit
can be lled with grease and dirt and
may be causing extra pressure due
reduced air ow cross-section area.
Clean or replace air ducts upstream of the ecology unit.
The unit’s
operation is
noisy.
Screws and bolts may have come
loose in vibration attenuators or
damage may have occurred at
attenuators.
Check screws and bolts, tighten any loose ones using appropriate
equipment.
During the handling of the ecology
unit, parts are used to stabilize the
base of the fan-motor group and to
prevent vibration attenuators from
breaking. These parts may not have
been removed during commissioning.
Remove the stabilizing parts from the fan-motor base.
The fan-motor group may have shifted
off axis, and may be scraping the
funnel.
Check the connections of the fan-motor group with the base, and of
the fan base to the oor of the unit. If there are any loose screws or
bolts, align the fan-motor group along the correct axis and tighten all
screws and bolts.
Damage may have occurred in fan
blades, causing imbalance during
rotation.
Manually check the rotation of the fan. Check for any oscillation
during rotation and for any damage to fan blades. If there is damage,
contact the manufacturer.
Damage or exing may have occurred
in the oor on which the unit sits.
If the noise persists despite all checks, lift the unit with the aid of
proper equipment and a crane and check the oor. If there is a dent
or damage which may cause vibration, repair the ooring.
Crackling and
arcing sounds
are coming from
the device.
ESP collectors may have been re-
installed before being fully dried.
Remove the ESP collectors, and if they are not thoroughly dry, dry
and re-install them.
Plates of ESP collectors may be
excessively dirty.
Carry out the procedure described in the maintenance and cleaning
section regarding ESP.
Plates of ESP collectors may have
been bent.
Remove the ESP collectors, and if there is bending in the plates,
straighten the plates using appropriate equipment and re-install the
collectors. If there is irreparable damage, contact the manufacturer.
Solid particles may have been left
between ESP collectors.
Remove the ESP collectors. Check for solid particles on the plates and
inside the section, and clean any with a clean cloth.
One or more of ESP ionizer wires may
be broken.
Remove the ESP collectors. If an ionizer wire is broken, install a new
ionizer wire as described in the maintenance and cleaning section. If
there are no ionizer wires available, contact the manufacturer.
ESP collectors may not be in contact
with one another.
When ESP collectors are placed one after the other, the sections
transmitting and receiving the current must be in contact with one
another.
Unit is not
working.
Your unit’s emergency stop button
may have been pressed or its cam
switch may have been brought to the
off position.
Check the emergency stop button and the cam switch. If they are off,
turn them on.
The unit may not be receiving
electrical current.
Make sure that the panel to which the unit is connected is active,
and that the electrical cable connections to the panel and the unit
have been made properly. If the panel is not active, render it active.
If there are any loose or dislodged electrical connections, correct as
needed.
