CAUTION!
Application of Dust Control Equipment
•Combustible materials such as buffing lint, paper, wood, aluminum or steel
dust, weld fume, or flammable solvents represent fire or explosion hazards.
Use special care when selecting and operating all dust or fume collection
equipment when combustible materials are present to protect workers and
property from damage due to fire and/or explosion. Consult and comply with
National and Local Codes relating to fire or explosion and all other appropriate
codes when determining the location and operation of dust or fume collection
equipment.
•When combustible materials are present, consult with an installer of fire
extinguishing systems familiar with these types of fire hazards and local fire
codes for recommendations and installation of fire extinguishing and explosion
protection systems. Donaldson Torit dust collection equipment is not equipped
with fire extinguishing or explosion protection systems.
• DO NOT allow sparks, cigarettes or other burning objects to enter the hood or
duct of any dust or fume control equipment as these may initiate a fire or
explosion.
• For optimum collector performance, use only Donaldson Torit replacement
parts.
Warning – Improper operation of a dust control system may contribute to
conditions in the work area or facility that could result in severe personal injury
and product or property damage. Check that all collection equipment is properly
selected and sized for the intended use.

1.0 Product Introduction
The dust collector is used for the collection of
airborne dust and particulate. Whether in
answer to the problem of air pollution, or as
part of a manufacturing process, the dust
collector provides highly efficient and
continuous on-line dust collection.
The filter elements are the heart of the dust
collector. These filter elements help ensure
the only cleaned air is returned to the plant
environment.
During operation, contaminated air enters the
dust collector through the dirty air inlet area
and passes through the filter elements. Dust
is collected on the surface of the filter
elements. The filtered air flows through the
centre of the filter elements into the clean air
chamber, where it exhausts through the
clean air outlet re-circulated into the
environment.
To ensure the optimal performance of your
dust collector it is necessary that the filter
elements are cleaned automatically
sequentially. During the filter sequence, the
timer energizes a solenoid valve, causing the
corresponding diaphragm valve to send a
pulse of compressed air through the filter
elements (from the inside outwards),
removing the collected dust from the outside
surface of the filter elements. The dust falls
through the hopper into the dust disposal
system.
2.0 Installation
Ensure all persons carrying out work on the
supplied equipment follow any relevant
recognized standards or codes and are
competent to do so.
2.1 Compressed Air Connection
Compressed air pressure must be at 6 bar.
Be sure that all compressed air components
are adequately sized to meet the maximum
system requirements of 45 Nliters per pulse
at 6 bar supply pressure (= design pressure).
Compressed air supply has to be both oil and
moisture free.
Connect the compressed air supply line to
the compressed air connection of the dust
collector.
A compressed air shut-off valve, a filter/water
separator with automatic condense drain, a
pressure regulator with gage must be
installed on the compressed air supply line.
2.2 Electrical Connection
Enter the cable through the cable gland
locate at the lower right corner of the
collector. And enter the cable to the control
box through the cable gland locate at the
bottom of the enclosure. Please follow the
electrical diagram provided for connection.
Do not install in classified hazardous
atmospheres without an enclosure rated for
the application.

Inlet Schematic
2.3 Inlet Duct Connection
The inlet duct is sent loose with the unit.
Connect it to the inlet flange with self-tapping
screws as shown on figure 3. All connections
have to be sealed properly.
3.0 Start-up and Operation
Check that the outlet of the fan is free of
debris before starting.
Make sure the dust disposal system is
properly installed under the hopper.
With new filter elements the airflow should be
adjusted to the nominal value by closing the
damper valve.
Check if the access doors are closed.
Switch main power on and press
switch ’start’.
Adjust the damper to the desired airflow.
Turn on the compressed air supply. Adjust to
6 bar of pressure with the compressed air
regular.
The cleaning cycle only starts when
necessary. For customized setting see the
controls manual.

Replacing of Filter Elements
When replacing diaphragm assembly make
sure the marking "THIS SIDE OUT" on
diaphragm assembly faces valve bonnet and
that bleed hole in diaphragm assembly is in
alignment with cavity in valve body and
bonnet. The external contours of the
diaphragm, body and bonnet must all be in
alignment.
Replace bonnet bolts and tighten in a
criss-cross manner.
4.0 Service
4.1 Dust Removal
Do not let the dustbin overfill. It can cause
poor dust collector performance.
Turn off the dust collector and empty the
dustbin on a regular base (recommend to
empty the dustbin when 1/2 full).
For the spark trap: do not forget to empty it.
Use a vacuum cleaner through the access
cover on the spark trap.
4.2 Replacing of Filter Elements
Caution
：
When the airflow is low or the differential
pressure is too high and alarm, must change
the filter elements. After operating more than
2000—4000 hours continuously, must
change the filter elements.
All filter elements should be changed at the
same time.
Do not drop the new filter element on the
floor or any other hard surface. It is
necessary to clean the dust of the tube sheet
all around the opening to ensure a positive
seal of the gasket.
Slide the new filter element along the yoke
with the gasket end facing inward towards
the clean air chamber.
Reinstall the cover and screw the wing nut
clockwise onto the yoke. Tighten securely, to
prevent leakage.
Caution
Disconnect electrical power before
servicing.
Shut off and bleed compressed air
supply before servicing any compressed
air components.
The filter elements are cleaned
automatically and sequentially. Don’t
move out the filter elements and clean.

5.0 Trouble shooting
WARNING
Disconnect all power before servicing to prevent injury or extensive
damage.
Direct compressed air supply towards human body or equipment will cause
serious injury, shut off and bleed compressed air supply before servicing
any compressed air components.
Automatically cut off of system power indicates abnormal function of
electrical components. Requires a qualified electrician according to local
codes to check all electrical work.
