1.4 Theory of Operation
1.4.1 The exhauster draws dust-laden air through the
ducting from the ventilated area, and through the filter
cartridges. As the air passes through the cartridges,
dust accumulates on the outer surface. Cleaned air
flows through the center of the cartridges, through the
exhaust ducting, and out the exhauster. The
accumulated dust is periodically released from the
cartridges by a pulse of compressed air. A typical
general arrangement with call-outs used in the manual
are shown in Figure 1.
1.2 Hazard Alerts
1.2.1 Clemco Industries Corp. uses signal words, based
on ANSI Z535.2-1991, to alert the user of a potentially
hazardous situations that may be encountered while
operating this equipment. ANSI's definitions of the signal
words are as follows:
This is the safety alert symbol. It is used
to alert the user of this equipment of
potential personal injury hazards.
Obey all safety messages that follow this symbol to
avoid possible injury or death.
1.4.2 RPH Dust Collectors utilize reverse pulse jet
cartridge filters. Compressed air used for the pulse is
released from the pulse manifold by quick-release
diaphragm pulse valves. At regular timed intervals the
sequence timer sends a signal to one of the solenoid
valves, releasing a pulse of air, which in turn opens the
respective diaphragm valve. The momentary opening of
the valve releases a burst of compressed air from the
manifold to the clean air side of the filter cartridges,
thus reversing the air flow to remove accumulated dust.
CAUTION
Caution used without the safety alert symbol
indicates a potentially hazardous situation
which, if not avoided, may result in property
damage.
1.4.3 Each solenoid and diaphragm valve is opened
in sequence until all cartridges have been cleaned
once, and then the cycle is repeated. If the switch on
the sequence panel is kept in the "on" position, the
sequence control panel energizes when the exhauster
is turned on, and stops when the exhauster is turned
off.
CAUTION
Caution indicates a potentially hazardous
situation which, if not avoided, may result in
minor or moderate injury.
1.4.4 The timers that control the "on" and "off" time of
the air pulse are located in the sequence control panel.
The "on" time should never be adjusted. The "off" time
controls the length of time between each pulse. The
shorter the "off" time, the more frequent the pulse
cycles. See Section 4.2.
WARNING
Warning indicates a potentially hazardous
situation which, if not avoided, could result in
death or serious injury.
1.4.5 The differential pressure gauge shows the
pressure difference between the dirty and clean side of
the filters. The gauge helps determine the proper
setting for the timer "off" time.
DANGER
Danger indicates an imminently hazardous
situation which, if not avoided, will result in
death or serious injury.

2.0 ASSEMBLY AND INSTALLATION
2.1.1 The dust collector must be located on a sound
footing.
WARNING
Weight and bulk of the components may require
that erection and placement of the collector be
performed by personnel experienced with
handling structural steel, and able to safely
operate material handling equipment needed to
erect the collector. Failure to recognize and avoid
hazards associated with handling structural steel
could result in serious injury or death.
WARNING
All footings must be designed by a qualified
engineer. Inadequate footing could result in
hazardous shifting of the collector and ducting,
which could result in death or serious injury.

RPH DUST COLLECTOR Page 3
2.2 Assembly
CAUTION
All seams assembled on the job site must be
sealed to weather-tight condition. Use mastic
tape and caulking on all seams as shown on the
assembly drawings.
2.2.1 The degree of assembly depends on the size and
style of the collector. There may be exceptions; but they
are usually as follows:
• RPH-2, RPH-3, RPH-6 & RPH-8: Factory assembled,
each requires locating and anchoring to a sound footing,
and assembly of the exhauster and ducting.
• RPH-4, RPH-10, RPH-12, & RPH-16: Requires field
assembly of the leg/hopper assembly and body, and
assembly of the exhauster and ducting. It must be located
and anchored to a sound footing.
• RPH-20 and larger: Requires field erection of the
structural leg and frame assembly, assembly of the hopper
and body, ladder, hand rail, exhauster and ducting. It must
be located and anchored to a sound footing.
2.2.2 Erect the collector as shown in the enclosed
assembly drawings. Pay special attention to the orientation
of the inlet and outlet duct openings, access doors, ladder,
handrail, and exhauster location. If the collector is part of a
facility, use the general arrangement drawings for the
placement of the components.
2.3 Anchors
WARNING
All anchors must be calculated and specified by
a qualified engineer. Inadequate anchoring to
the footing could result in hazardous shifting of
the collector and ducting, which could result in
death or serious injury.
2.3.1 Anchor modules to the footing with anchors
specified by a qualified engineer.
2.4 Exhauster Assembly
NOTE: 3600 cfm and larger exhausters are floor mounted,
and require ducting from the collector, and an exhaust
stack with a damper adjustable from 0-80% closed.
Smaller exhausters are mounted on the collector body,
and do not require additional ducting.
2.4.1 Anchor the exhauster in position. NOTE:
Positioning of the exhauster must coincide with the
placement of the outlet ducting. Use temporary anchors
until the ducting is in place.
2.4.2 Attach exhaust stack and damper assembly to the
exhauster outlet.
2.5 Ducting
2.5.1 Clemco Industries Corp. does not usually supply
ducting, but does provide a general arrangement drawing
for suggested ducting.
2.5.2 The illustration in Figure 2 shows a typical ducting
and exhauster arrangement. The illustration is not to be
used to fabricate ducting.
CAUTION
All ducts, joints, and connections must be tight.
Any leaks will affect the overall performance of
the system.
The joint between the duct and exhauster
housing must be flexible, such as canvas or
rubber with band clamps. The ducting must be
self supporting. NO LOAD IS TO BE APPLIED TO
THE EXHAUSTER BY THE DUCTING.
Ducting must be supported sufficiently to place
no load on connecting equipment.
2.5.3 All duct work must be performed by qualified
licensed contractors familiar with industrial ventilation
practices, and must conform to local codes. Where state or
local codes conflict with each other or with specifications
by Clemco Industries Corp., the more stringent regulation
shall be followed.

2.6 Electrical Connections
WARNING
Shorting electrical components could result in
death, serious electrical shocks, or equipment
damage. All electrical work, or any work done
inside an electrical panel, must be performed by
qualified electricians, and comply with
applicable codes.
NOTE: Wiring schematic for the sequence panel,
exhauster motor, control panel and other electrical
accessories are included when accessories are
furnished by Clemco Industries Corp. Refer to the Table
of Contents for the locations of the electrical wiring
schematics.
2.6.1 The dust collector should be controlled by a
separate switch to enable operation before and after all
other components in the system. Wire all other
components to start in series to prevent the overloading
of any component. The last segment in the system that
the abrasive reaches should start first and stop last. A
complete blast and recovery facility will have the dust
collector start first; followed by the abrasive cleaner,
bucket elevator, and floor recovery. Shutdown is in
reverse order.
2.6.2 Electrical connections are required for the
exhauster motor and sequence control panel. Unless the
collector is operated in conjunction with a Clemco-
provided system control panel, a customer supplied
starter is also required. When the exhaust fan is
connected, make sure it rotates in the direction of the
scroll.
2.6.3 Sequence panel wiring must enter through the
bottom of the panel to avoid potential leakage.
2.7 External Grounding
2.7.1 To dissipate static electricity, attach an external
grounded wire from an earth ground to the grounding lug
located next to the sequence panel.

RPH DUST COLLECTOR Page 5
2.9 Dust Containers
2.8 Compressed Air Connections
2.9.1 Attach a flex hose and dust drum lid to the bottom
of the dust hopper.
CAUTION
The air source for the filter pulse must be 35 to
50 degrees Fahrenheit dew point and be free of
any oil contaminants. If line air does not meet
this requirement, an optional air dryer is
recommended. Moisture or oil contaminants in
the pulse system will decrease cartridge life
and filtering efficiency
2.9.2 Place a dust drum under the dust lid and
securely attach the lid to the drum.
CAUTION
All flex hose connections made at the bottom of
the hopper and the lid must be air tight.
2.8.1 An air line must be supplied to the pressure
regulator located on the pulse manifold inlet. The size of
the line depends on the size of the collector. The
compressor and piping supplying air to the pulse
manifold must be large enough to provide at least 3 cfm
per cartridge. The air line should not be smaller in
diameter than the manifold inlet at the regulator.
3.0 OPERATION
WARNING
All persons operating this equipment must be
made aware of the hazards of abrasive blasting,
and handling toxic materials, including red lead
and silica dust. Toxicity and health risk vary
with the type of media, and dust generated by
blasting. Identify all material being removed by
blasting, and obtain a materials safety data
sheet for the blast media.
2.8.2 Purge the air supply line to remove moisture or
other foreign material before connecting it to the pulse
manifold.
2.8.3 Connect tubing to the differential pressure
indication panel as shown in Figures 1 and 3.

3.2 Initial Start-up
WARNING
Do not look into the exhauster outlet while the
fan is turning. Injury to the eye or face could
occur from objects being ejected from the
exhauster.
3.2.1 Check motor rotation by jogging the starter
(momentarily turn switch on and off). This will cause the
motor to rotate slowly. Look through the slots in the fan
housing on the end of the motor where rotation of the
fan can easily be observed. Proper rotation is indicated
by the arrow on the exhauster housing. The fan should
rotate toward the scroll.

RPH DUST COLLECTOR Page 6
CAUTION
Do not pulse new dust collectors or
replacement cartridges until the cartridges are
properly seasoned. See Section 6.2. Pulsing
unseasoned cartridges could cause premature
cartridge failure or decrease the efficiency of
dust collector.
3.2.2 With the sequence switch off, pressurize the
pulse manifold to 100 psi and check pneumatic
connections for leaks.
3.2.3 Turn pulse pressure to 20 psi and switch the
pulse sequence on. Check the air pulse and sequence
of the diaphragm pulse valves, solenoids, and panel
timer. After all items are checked, adjust the pulse
pressure to 70 psi, and turn the sequence switch off.
Do not switch the sequence panel on until the
cartridges are seasoned per Section 6.2.
3.3 Operational Start-Up
3.3.1 Make sure access doors are closed, and dust
drums are secure.
3.3.2 Check to make sure the sequence switch is "on".
CAUTION
Do not turn the sequence switch on until the
cartridges are seasoned. See Section 6.2.
3.3.3 Start the exhauster at the control panel.
3.3.4 Pressurize the pulse manifold and check the
manifold pressure.
3.4 Shutdown
3.4.1 Allow the system to run until all system
components are empty (see the accessory components
operation manual) and all areas ventilated are free of
airborne dust.
3.4.2 Turn off the exhauster.
3.4.3 Shut off the air supply to the pulse manifold.
3.4.4 Drain the pulse manifolds. The drain cock is
mounted at the bottom of each manifold. See Figure 1.
Drain whenever the air supply is turned off.
3.4.5 Empty all dust receptacles.
4.0 ADJUSTMENTS
4.1 Pulse Manifold Pressure
4.1.1 A pressure regulator and gauge is provided on the
manifold inlet to adjust pressure to 70 psi. An additional
manifold pressure gauge is mounted on the differential
pressure gauge panel to enable monitoring pressure from
ground level. The panel is usually mounted on one of the
dust collector legs. See Figure 3.
4.2 Pulse Sequence Control Panel and Timer
4.2.1 A toggle switch mounted on the sequence control
panel cover (located on the dust collector stand), enables
or disables the sequencer. If the switch is "on", the pulse
sequence will automatically start whenever the dust
collector exhauster is started. If the switch is "off", the pulse
sequence will not occur. The switch should be left "off" (no
pulse) until the cartridges are seasoned. See Section 6.2.
4.2.2 The timer is factory set at 40 seconds "off" and
15/100 of a second "on". Every 40 seconds, one filter bank
is pulsed in sequence until all filters have gone through a
cycle.
4.2.3 As the filters cake with dust, the pulse may not
clean them well enough to bring the differential pressure
gauge below the recommended changeover pressure of
4". A constant reading higher than 4" is an indication that
more frequent pulse cycles or higher pressure are needed.
When the differential pressure gauge shows a constant
pressure difference greater than 4", adjust the "off" time
setting by half. DO NOT ADJUST "ON" TIME. Increasing
on time will consume more air, but will NOT increase
cleaning efficiency.
4.2.4 When the frequency of the pulse cycles will not
lower the differential pressure to less than 4", or if a
decrease in the efficiency is noted, increase pulse
pressure in increments of 10 psi until the maximum of 100
psi is reached.
4.2.5 When the frequency of the pulse cycles and
higher pulse pressure will not lower the differential
pressure below the changeover pressure of 4" w. c., the
filter cartridges should be replaced, and the timer "off" time
should be reset to 40 seconds, and pressure set to 70 psi.
See Section 6.1.

5.0 PREVENTIVE MAINTENANCE
WARNING
Make sure the following conditions are met
before performing any maintenance on the
collector.
•Turn off compressed air supply and drain air
from pulse manifolds.
•Turn off sequence control switch.
Failure to observe the above warnings could
result in serious injury from the sudden release
of trapped compressed air or the operator
loosing balance.
•Always wear a properly fitted and
maintained, NIOSH approved respirator, eye
protection and safety clothing when
servicing dust laden areas of the dust
collector.
Failure to do so could result in serious eye
irritation and lung disease or death. Toxicity
and health risk vary with type of media, and
dust generated by blasting. Identify all material
that is being removed by blasting, and obtain a
materials safety data sheet for the blast media.
5.1 Daily
5.1.1 Empty dust drums.
NOTE: Check dust drums daily until the dust collection
rate is determined. At that time setup a program to
empty the drums before they are 2/3 full. Dust should
never accumulate in the hoppers.
5.1.1.1 Empty and/or replace the drums, ensuring that
the drum lids are secure.
5.1.2 Check the exhaust air during a pulse cycle.
5.1.2.1 If dust is emitting from the exhauster, filters are
leaking or damaged. Check immediately. To determine
which cartridge in leaking, turn the sequence switch off,
open the top access door and check the inside of the
collector for dust trails. NOTE: A small amount of dust
egress is normal for a short period when cartridges are
new.
5.1.3 Check the differential pressure gauge at least
once daily, and more often under dusty conditions. Turn
the sequence switch "on" or "off" as necessary to
maintain optimal differential pressure of 2" to 4". If the
reading is continually high (greater than 4"), adjust
pressure and/or sequence timing per Sections 4.1 and
4.2.
5.2 Weekly
5.2.1 Check the inside of the collector for moisture. If
moisture is caused by leaks, repair immediately.
5.2.2 Clean the differential pressure gauge in-line dust
filter located behind the gauge panel. See Figure 3.

6.1 Replacing Filter Cartridge
WARNING
Make sure the following conditions are met
before performing any maintenance on the
collector.
•Turn off compressed air supply and drain air
from pulse manifolds.
•Turn off sequence control switch.
Failure to observe the above warnings could
result in serious injury from the sudden release
of trapped compressed air or the operator
loosing balance.
•Always wear a properly fitted and
maintained, NIOSH approved respirator, eye
protection and safety clothing when
servicing dust laden areas of the dust
collector.
Failure to do so could result in serious eye
irritation and lung disease or death. Toxicity
and health risk vary with type of media, and
dust generated by blasting. Identify all material
that is being removed by blasting, and obtain a
materials safety data sheet for the blast media.
6.1.1 Lock out and tag out the compressed air supply
and electrical power.
6.1.2 Empty the dust receptacles.
6.1.3 Open the top access door.
6.1.4 Remove the wing nuts securing the filter hold-

RPH DUST COLLECTOR Page 8
6.1.6 Remove all filter cartridges. A small amount of
force may be necessary to loosen the seal of the filter
gasket.
7.0 TROUBLESHOOTING
WARNING
6.1.7 When all filters are removed, clean the inside of
the collector to remove loose dust or hardened dust clods,
particularly from the cartridge sealing surface, and the
clean-air side (top side) of the cartridge sheet.
Shut down the collector immediately when dust
emits from the exhauster. Check to make sure
filters are correctly seated and not worn or
damaged. Prolonged breathing of abrasive dust
and blasting by-product dust could result in
serious lung disease or death. Short term
ingestion of toxic dust such as red lead, poses an
immediate danger to health. Identify all materials
that are to be removed by blasting, and obtain a
material safety data sheet for the blast media.
6.1.8 Install new filter cartridges; center each cartridge,
install venturi tube, and secure with hold-down plate as
each cartridge is installed.
6.1.9 If necessary, replace the gasket on the access
door. Close the access door and secure.
6.1.10 Reset timer "off" time to 40 seconds, and set
pulse pressure to 70 psi.
7.1 Collector Not Pulsing
6.1.11 Turn the sequence panel off and season
cartridges per Section 6.2. 7.1.1 Check the manifold pressure gauge. If low,
check the compressed air supply; look for a closed
supply valve.
6.2 Seasoning Cartridges
7.1.2 Check function of the pressure regulator located
on the pulse manifold inlet.
6.2.1 New cartridges must be seasoned. Cartridges are
seasoned by letting a dust cake develop on the filter media
before starting the pulse cycle.
7.1.3 Make sure the sequence switch located on the
panel cover is "on".
6.2.2 Operate the dust collector without pulsing
(sequence switch turned off) until the differential pressure
gauge reads the recommended changeover pressure of
4". At that point turn on the sequence switch to start the
pulsing cycle.
7.1.4 Check the fuse in the sequence control panel.
Replace as necessary.
7.1.5 Have a qualified electrician check for electrical
malfunction; check the supply voltage to the pulse
sequence board. Check outlet voltage to solenoids.
6.3 Tube fittings
7.2 Some Cartridges Not Pulsing
6.3.1 If it becomes necessary to remove or replace the
tubing between quick-release valves and panel, be sure
the tubing does not bottom out in the fitting. If the tubing is
inserted too far into the fitting it will block the air passage,
and cause the pulse to malfunction.
7.2.1 Solenoid defective. Have a qualified electrician
check for electrical malfunction.
7.2.2 Check the diaphragm pulse valves.
7.2.3 Check for blockage in the tubing between the
diaphragm pulse valve and solenoid assembly.
