OPERATIONAL INSTRUCTIONS


OPERATOR SAFETY EQUIPMENT




OSHA regulation 1910.134 requires appropriate respiratory protection for blast operators and workers in
the vicinity of blasting. These workers must wear properly-fitted, properly-maintained, NIOSH-approved,
respiratory protection that is suitable for the job site hazards. Blast respirators are to be worn only in
atmospheres not immediately dangerous to life or health from which wearers can escape without use of
the respirator.

The employer must develop and implement a written respiratory protection program with required
worksite- specific procedures and elements for required respirator use. The employer must provide
effective training to employees who are required to use respirators. The training must be comprehensive,
understandable, and recur annually, and more often if necessary.

NEVER use abrasives containing more than one percent crystalline silica. Fatal diseases, such as silicosis,
asbestosis, lead or other poisoning, can result from inhalation of toxic dusts, which include, but are not
limited to, crystalline silica, asbestos, and lead paint. Refer to NIOSH Alert 92-102; and OSHA CPL 03-00-007:
“National Emphasis Program – Crystalline Silica”, in which OSHA describes policies and procedures for
implementing a national emphasis program to identify and reduce or eliminate health hazards from exposure
to crystalline silica. Numerous topics associated with the hazards of crystalline silica in silica blasting sand
can be found on http:// osha.gov/. Clemco urges users of silica blasting sand to visit this website, and read
and heed the information it contains.

Always make sure the breathing air supply (respirator hose) is not connected to plant lines that supply
gases that include, but are not limited to, oxygen, nitrogen, acetylene, or other non-breathable gas. Never
modify or change respirator air line connections without first testing the content of the line for safe
breathing air. Failure to test the line may result in death to the respirator user.


• Breathing air quality must be at least GradeD,
as defined by the Compressed Gas Association
specification G-7.1, per OSHA Regulation 29 CFR
1910.134. When compressed air is the breathingair
source, a Clemco CPF (suitable sorbent bed filter)
should be used. Respirator hose connecting the
respirator to the filter must be NIOSH approved.
Non- approvedhose can cause illness from
chemicals employed to manufacture the hose.
• All workers must always wearNIOSH-approved
respirators when any dust is present. Exposure to
dust can occur when handling or loading abrasive,
blasting, cleaning up abrasive, or working in the
vicinity of blasting. Before removing the respirator,
test the air with a monitoring device to ensure it is
safe to breathe.
• Clemco respirators DO NOT removeor protect against
carbon monoxide or any other toxic gas. Monitoring
devices must be used in conjunction with the respirator to
ensure safe breathingair. Always locate compressors and
ambient air pumps where contaminatedair will not enter
the air intake.

• Always use Clemco lenses with Clemco respirators;
installing non-approvedlenses voids the NIOSH approval.
Respirator lenses aredesigned to protect the wearerfrom
rebounding abrasive; they do not protect against flying
objects, heavyhigh-speed materials, glare,liquids, or
radiation.

BLAST MACHINES AND REMOTE CONTROLS



OSHA regulation 1910.169 describes the necessity of pressure relief valves on compressed air equipment. Do not
operate blast machines with air compressors that are not equipped with properly functioning pressure relief valves.
OSHA regulation 1910.244(b) requires the use of remote controls on blast machines.
Serious injury or death can result from many sources, among them:
Involuntary activation of the remote controls. Never modify or substitute remote control parts; parts are not
compatible among different manufacturers. Welding hose is not suitable for remote control hose. Its ID and material
composition make it unsafe for remote control use.
Exceeding the maximum working pressure. Clemco blast machines are built to ASME-code and carry a ‘U’ or ‘UM’
stamp, and National Board/serial number. Every machine is marked with its maximum working pressure. Never
exceed the maximum working pressure limits of the blast machine.
Uncontrolled blast stream. High-velocity abrasive particles will inflict serious injury. Always point the blast nozzle
in the direction of the blast surface only. Keep unprotected workers out of the blast area.
Welding on the blast machine. Never weld on the blast machine; welding voids the National Board approval and
may affect the dimensional integrity of the vessel.
Moving the blast machine. Never manually move a blast machine containing abrasive, any machine containing
abrasive must be moved with appropriate mechanical lifting equipment.



HOSES, COUPLINGS, AND NOZZLE HOLDERS

The inside diameter (ID) of air hoses, fittings, and connections
should be at least four times larger than the nozzle orifice size. Blast
hose ID should be three to four times the size of the nozzle orifice.
Example: a #6 nozzle (3/8” diameter orifice) calls for 1-1/2” ID blast
hose and 1-1/2” ID or larger compressor hose. All hose runs should be
kept as short as possible and run in as straight a line as possible to
reduce pressure loss.
To install, squarely cut the end of the hose so that it fits snugly
against the coupling or hose end shoulder. Always use the screws
recommended by the manufacturer ensuring that they do not
penetrate the inner wall. Make sure the couplings tightly fit the hose.
Install cotter pins at every connection or use couplings with built-in
lock-springs to prevent disengagement. Install safety cables at all
connections to prevent whipping if hoses disengage or blow out.

MAINTENANCE AND REPAIR

Completelyreadand follow all service instructions and recommended maintenance intervals. Always shut off compressor and
depressurize blast machine beforeperforming any maintenance. At everyservice interval, clean all filters, screens, and alarm systems. If
spring-loaded abrasive valves areused, always cage spring beforedisassembly.

[IV]
DAILYSET‐UPCHECKLIST





Make sure all blast operators are properly trained and suitably attired with a blast suit, safety boots, leather gloves, respiratory and hearing protection. Every day before start up,
check all equipment components, including piping, fittings, and hoses, and valves, for leaks, tightness, and wear. Repair or replace as needed. Use the following checklist.

1. PROPERLY-MAINTAINED AIR COMPRESSOR sized to provide
sufficient volume (cfm) at given pressure for nozzle and other tools. ADD 50%
volume (cfm) reserve to allow for nozzle wear. Use large compressor outlet and
air hose (at least 4 times the nozzle orifice diameter). For oil-lubricated
compressors, the employer shall use a high- temperature or carbon monoxide
alarm, or both, to monitor carbon monoxide levels. If only high-temperature
alarms are used, the air supply shall be monitored at intervals sufficient to
prevent carbon monoxide in the breathing air from exceeding 10 ppm. Follow
the manufacturer’s checklist and maintenance instructions.
2. BREATHING-AIR COMPRESSOR (or oil-less ambient air pump)
capable of providing Grade D quality air, located in a dust free area. Read # 1
above.
3. CLEAN, PROPERLY-MAINTAINED NIOSH-APPROVED SUPPLIED-AIR
RESPIRATOR
worn by blast operators, and other workers exposed to blast dust.
Make sure all respirator components are in place — all lenses, inner collar, and
cape. Thoroughly inspect all components for wear. The NIOSH approval (approval
number is listed in the owner’s manual) is for a complete assembly from point of
attachment on the CPF (sorbent bed) filter to the complete respirator. Substitution of
any part voids the NIOSH approval.
4. CARBON MONOXIDE MONITOR/ALARM installed at the CPF filter or
inside the supplied-air respirator for monitoring for the presence of deadly CO gas
and warning the operator(s) when the CO level reaches an unacceptable level.
When an ambient air pump is used for breathing air, a CO monitor provides a
measure of safety. Read # 1 above.
5. BREATHING-AIR FILTER (OSHA-REQUIRED sorbent bed filter) for
removal of moisture and particulate matter in the compressed air breathing-air
supply. Monitor the condition of the cartridge and replace when odor is detected or
at 3 month intervals, whichever comes sooner. The breathing air filter does NOT
detect or remove carbon monoxide (CO). Always install a CO monitor/alarm.
6. BLAST MACHINE (bearing U or UM stamp, National Board Number, and
Maximum Working Pressure) sized to hold a 30-minute abrasive supply. Examine
pop-up valve for alignment. Check piping, fittings, screens, valves for tightness,
leaks, and wear. Always ground the machine to eliminate hazard of static shock.
Install a blast machine screen to keep out foreign objects. Use a blast machine
cover if left outdoors overnight. Never exceed the maximum working pressure of the
vessel.
7. AIR LINE FILTER (moisture separator) installed as close as possible to the
blast machine inlet and sized to match the size of the inlet piping or larger air supply
line. Clean filter and drain often. Damp abrasive causes operational problems.

8. REMOTE CONTROLS are required by OSHA and must be in perfect
operating condition. Test and check all components to ensure all parts are present
and fully functional. Use genuine replacement parts. NEVER mix parts from different
manufacturers. Never use welding hose for remote control hose.

9. BLAST HOSE should have an inside diameter sized to suit the blast nozzle.
The ID should be three to four times the size of the nozzle orifice diameter. Blast hose
should be arranged in as straight a line as possible from the blast machine to the
work area, avoiding sharp bends.

10. COUPLINGS AND NOZZLE HOLDERS should fit snugly on the hose and
be installed with manufacturer recommended screws. Coupling lugs must snap firmly
into locking position. Gasket must always be used to form a positive seal, and cotter
pins must be installed. Replace gasket when wear, softness or distortion is detected.
Check nozzle holder for thread wear; replace at any sign of wear. Install safety cables
at all connections.

11. NOZZLE orifice size should be checked and nozzle replaced when worn
1/16” from original size. (No. 5 nozzle has 5/16” orifice diameter; replace when it
measures 3/8”). Threads should be inspected daily for wear and nozzle should be
replaced when wear is detected. Always use a nozzle washer.

12. ABRASIVE must be a material specifically manufactured for blasting. It
should be properly sized for the job. Check material safety data sheet for free-
silica, cyanide, arsenic, lead and other toxins and avoid use when these toxic,
harmful substances are present.

SURFACE TO BE BLASTED should be examined for hazardous substances.
Take appropriate protective measures as required by OSHA to ensure the blast
operator, other workers in the vicinity, and any bystanders are properly protected.

1.5 Reclaimer
NOTE: Replaceable rubber reclaimer liners prolong
service life of the reclaimer, and should be installed when
using aggressive media as noted in Section 1.6.4. The
standard 900 cfm reclaimer is of universal design to
accept liners installed at time of purchase or field-installed
later. Rubber liners are shown in Section 14.1, Figure 12.
1.5.1 Reclaimers used with M-Sections®are pull-thru
type, using an exhauster mounted on the outlet side of
the reverse-pulse dust collector to pull recovery air
through the reclaimer and dust collector filter
cartridge(s). The M-Section®duct, reclaimer, and dust
collector are under negative pressure.
1.5.2 Standard reclaimers are 900 cfm. All references
made in these instructions are for 900 cfm reclaimers. If
a larger reclaimer is requested, the system will be
furnished on an engineered project order and will include
a separate reclaimer manual.
1.6 Blasting Media
WARNING
Abrasives and dust from blasting may contain
toxic materials (e.g., lead paint, silica) that are
hazardous to workers. Obtain a safety data
sheet (SDS) for the blast abrasive and identify
all substances removed by the blasting
process.
• Silica sand (crystalline) can cause silicosis,
lung cancer, and breathing problems in
exposed workers.
• Slags can contain trace amounts of toxic
metals such as arsenic, beryllium, and
cadmium and have the potential to cause lung
disease.
NO DUST IS SAFE TO BREATH. DUST
PRODUCED FROM ANY ABRASIVE OR FROM
THE BLASTING PROCESS CAN CAUSE
SERIOUS LUNG DISEASE AND DEATH WHEN
INHALED. It is the employer’s responsibility to
train employees to identify hazardous
substances and to provide suitable policies,
procedures, monitoring, recordkeeping and
personal protective equipment.
1.6.1 Unless noted otherwise, standard M-Sections®
utilize most common reusable media between 60 and
180-mesh that is specifically manufactured for dry
blasting.
1.6.2 Steel: Steel shot and steel grit are not
recommended for use with standard M-Section®
pneumatic recovery systems. Smaller sized steel may be
used on engineered project equipment, but this
requirement must be stated ahead of time so that the
equipment may be modified accordingly.
1.6.3 Sand and Slag: Sand should never be used
because of the respiratory hazards associated with the use
of media containing free silica. Slags are not recommended
because they rapidly breakdown and are not recyclable,
making them unsuitable for blast room applications.
1.6.4 Silicon Carbide, Aluminum Oxide, and
Garnet: These are the most aggressive, high-volume
abrasives used in the blasting industry. These abrasives,
up to 36 mesh, may be used with a standard M-
Section®, but the service life of any equipment
components which come in contact with the abrasive will
be reduced. Use a nozzle lined with boron carbide with
these abrasives. To avoid unscheduled down time,
periodically inspect the M-Section®, reclaimer, reclaimer
booster exhauster, hoses, and nozzle for abrasive wear.
When occasionally using aggressive media, install an
optional aluminum oxide kit. When these abrasives are
used extensively, use a fully rubber-lined reclaimer. An
M-Section®with a lined bottom is optional as an
engineered project. Installation of rubber curtains on
blast room walls is recommended. Nozzles lined with
boron carbide are optional, but recommended to extend
nozzle wear life.
1.6.5 Glass Bead, #6 thru #12: Most beads are
treated to ensure free-flow operation even under
moderately high-humidity conditions. Glass beads
subjected to excessive moisture may be reused after
thorough drying and breaking up any clumps.
1.6.6 Lightweight and Fine-mesh Media: When
using lightweight (such as agricultural) media or fine
mesh (180-mesh and finer) media, the reclaimer inlet
baffle may need to be removed to retain media and
avoid carryover. Current 900 cfm reclaimers have a bolt-
on removable top, baffle removal and replacement is
easily accomplished by remove the top and bolt-on
baffle. If necessary to remove the baffle, make sure the
baffle bolts are put back into the reclaimer bolt holes.
Leaks in the reclaimer will cause problems with recovery
and carryover.
1.6.7 Plastic Media: M-Sections®with 60oslope and
blast machine with a 60oconical bottom are add-on
option that can be provided when specified at the time of
purchase. Refer to Clemco’s AEROLYTE brand.

3.0 PLACEMENT
WARNING
Failure to observe these warnings can result in
serious injury or death.
Weight and bulk of the components require
that erection and placement of the equipment
be performed by personnel experienced with
handling structural steel, and able to safely
operate material handling equipment needed to
assemble the equipment. Assembly personnel
must take care to recognize and avoid hazards
associated with handling this type of
equipment.
To move this equipment use the lifting eyes
that are provided on each segment. Never hoist
the equipment by the legs, handle or piping, or
with a sling through anything other than the
lifting eyes.
Keep the equipment level and upright when
moving and lifting. Use rope or cable to steady
the equipment during moving and placement,
and to prevent equipment from tipping.

elbow to the reclaimer inlet adaptor using the most direct
route with as few bends as possible to prevent wear.
4.3.2 When necessary, rotate the externally-
adjustable vortex cylinder to provide full access to the
adjustment handle.
4.3.3 Use a lift to raise the reclaimer over the blast
machine and storage hopper, and carefully lower it in
place, being careful not to damage the flange gasket. An
air leak at the flange will carry good media to the dust
collector. Bolt in place with fasteners provided.
WARNING
Do not work under the reclaimer while it is
hanging from the lifting device. Severe injury or
death can occur if the reclaimer is released
before it is secured to the storage hopper or

down the compressed air system.
9.0 LOADING AND UNLOADING MEDIA
9.1 Media Capacity
9.1.1 If media is recovered while blasting the storage
hopper must remain empty, media capacity in this
application is approximately 6 cubic feet. The blast
machine may be loaded with 6 cu. ft. of media through
the storage hopper access door. The system is full at 6-
cu. ft. when media reaches the level of the blast machine
pop-up valve.
9.1.2 If recovery does not occur until blasting is
finished, the storage hopper may be loaded with 6 cu. ft.
of media through the reclaimer access door. In this
application media capacity in a standard sweep-in
system is approximately 12 cu. ft. The system is full at
12 cu. ft. when media level is at the flange where the
reclaimer attaches to the storage hopper.
9.1.3 Overfilling will result in media carryover to the
dust collector and possible blockage in the M-Section®
or conveying hose.
9.2 Media Loading: If the system is completely
emptied, media can be loaded by pouring it into the M-
Sections®hoppers while the exhauster is running. When
adding media, recover all media, turn OFF the
exhauster, and pour clean, dry media into the storage
hopper through the reclaimer access door. Do not pour
media directly into the hoppers if the current media
level is unknown, as overfilling or blockage may
occur. Replenish with new media only after all media
has been recovered from the blast area.
9.3 Media Unloading: To empty the blast machine
and hopper of media, reduce pressure to 40 psi. Place
an empty container, such as a drum, in the blast room.
Close the choke valve, hold the blast hose securely, and
pressurize the machine by activating the control handle.
Be prepared for severe surging and recoil of the hose.
Direct media flow into the container. Empty the container

M-SECTION® SWEEP-IN PNEUMATIC RECOVERY SYSTEM Page 8

when full or before it is too heavy to maneuver, and
repeat the process until the machine is empty. If
complete purging of media is required, use a shop
vacuum to remove media residue in the hopper and
blast machine head.
10.0 ADJUSTMENTS
Refer to the appropriate manual to make adjustments to
the blast machine, dust collector, and operator safety
equipment.
10.1 Transition Inlet Damper, Figure 3
10.1.1 To adjust, loosen the weight on the damper
assembly, and plug two M-Section®hoppers. Start the
recovery system motor, and slide the weight on the rod
until the damper door just begins to open. Tighten the
weight to maintain the setting, and then remove the
hopper plugs.
Figure 3
10.1.2 Once adjusted, the damper will open to clear the
M-Section®transition should it become plugged.
10.2 Reclaimer Static-pressure
10.2.1 Constant static-pressure balance is necessary
for precise media separation. Correct static-pressure
varies with the size of reclaimer and the size, weight and
type of media.
10.2.2 Adjust static pressure using the dust collector
damper. Opening the damper (handle parallel with air
flow) increases air flow and static pressure, while closing
the damper (handle perpendicular to air flow) decreases
air flow and static pressure. The damper is located on
the inlet on a CDC-1 dust collector and on the exhauster
outlet on an RPH dust collector, refer to Figure 1 and the
dust collector manual. If the damper is not opened far
enough, there is not enough air movement through the
reclaimer to remove fines, resulting in dusty media and
may cause media blockage in the conveying hose. If the
damper is opened too far, there is too much air
movement through the reclaimer which can cause
carryover (usable media carried into the dust collector)
and result in excessive media consumption. Open only
as far as necessary to obtain a balance of media
recovery and dust removal without media carryover.
10.2.3 A manometer is useful when adjusting or
monitoring static-pressure. The optional manometer kit is
listed under Optional Accessories in Section 14.1. Refer
to Section 10.4 for operation. The following are static-
pressure starting points for given media. Static-pressure
may need to be lower with finer media and higher with
coarser media. Run the media through several recovery
cycles allowing the reclaimer to function with these
settings. Inspect the media in the reclaimer and fines in
the dust collector as noted in Paragraphs 10.2.4 and
10.2.5. Continue adjusting static pressure until optimum
media cleaning without carryover is attained.
Glass Bead No. 6 and 7 .......................... 3-1/2" to 4"
Glass Bead No. 8 to 13 ........................... 3" to 3-1/2"
Alox. 60 and coarser ..................................... 4" to 5"
Alox. 80 and finer .................................... 3" to 3-1/2"
10.2.4 To Remove More Fines: Open the damper
enough to increase static pressure by 1/4 inch.
10.2.5 To Remove Less Fines: Close the damper far
enough to decrease static pressure by 1/4 inch.
10.2.6 Operate the system until the media has gone
through several cycles before making additional
adjustments. The objective is to obtain a balance of
maximum dust removal without media carryover.
10.2.7 If the damper has been adjusted and carryover
or excessive dust in the media continues, adjust the
vortex cylinder per Section 10.3.
10.3 Externally-adjustable Vortex Cylinder
The vortex cylinder fine-tunes media separation. Before
adjusting the cylinder, adjust static pressure per Section
10.2. After adjusting static pressure and media has gone
through several recovery cycles, adjust the vortex cylinder
as follows.
10.3.1 Adjustments are made by loosening the handle's
tensioning knob and moving the handle to achieve the
correct setting. When the correct setting is established,
tighten the tensioning knob to prevent movement. Start
with the lever slightly to the right of the vertical, at about
the one o’clock position as shown in Figure 4.

Figure 4
10.3.2 To Remove More Fines: If there is too much
dust in the media, raise the cylinder by moving the lever
left toward "COARSE", in 1/4" increments at the indicator
plate. It may take a few recovery cycles to remove the
fines; allow the media to go through several recovery
cycles before determining if further adjustment is required.
10.3.3 To Remove Less Fines: If too much usable
media is being carried to the dust collector, lower the
vortex cylinder by moving the lever right toward "FINE",
in 1/4" increments at the indicator plate. Run the media
through several recovery cycles and check the dust
container to determine if further adjustment is required.
Note: If the cylinder is lowered too far, the reclaimer will
again begin to allow usable media to be carried over,
and cause abnormally high static pressure.
10.3.4 When using media finer than 180-mesh, the
reclaimer inlet baffle may also need to be removed.
Refer to Section 1.6.6.
10.4 Optional Manometer
NOTE: These instructions show several methods of
taking static-pressure readings (negative pressure) on
reclaimers using a flexible tube manometer. Use the
method best suited for the application. The instruction
explains the processes for taking periodic readings and
shows how to permanently install the manometer for
taking frequent readings The readings are reference
points so it doesn’t matter where the readings are taken
as long as they are always taken at the same location.
Taking readings at different locations can produce
different results. Static-pressure readings at the door are
generally 1/2" to 1" lower than those taken above the
reclaimer.
10.4.1 Refer to directions packed with the manometer
for preparation and operating instructions for the
manometer.
10.4.2 Connect one end of the 3/16" ID tubing to one of
the tubing connectors (elbow) at the top of the
manometer, by pushing it over the barbed adaptor.
10.4.3 Leave the needle protector on the needle and
insert the needle into the other end of the tubing. The
ends of the tubing must fit tight on the manometer and
needle; leaks will give inaccurate readings.
10.4.4 Open both manometer valves (elbows) per the
instructions with the manometer.
10.4.5 Magnets on the manometer hold it in position on
the reclaimer body. The manometer must be vertically-
plumb so the fluid is level on both sides.
10.4.6 Adjust the slide rule to align the zero with the
fluid level. Refer to the upper part of Figure 6.
10.4.7 Needle placement: The illustration in Figure 5
shows the manometer set-up for taking both periodic
and frequent static pressure readings.

10.4.7.1 Taking readings in the flex hose: Remove
the needle protector, and insert the needle into the flex
hose approximately 8" from the top of the reclaimer.
10.4.7.2 Taking readings at the reclaimer door: Open
the reclaimer fill door, remove the needle protector and
place the needle so the point is inside the door opening.
Carefully close the door on the needle. The side of the
needle will embed into the rubber, creating an airtight
seal.
Figure 6
10.4.7.3 Taking frequent readings using a permanent
fitting: A permanent fitting may be installed in the
reclaimer wall as shown in Figure 5 for taking frequent
static pressure readings. Permanent fittings must have a
barb to accommodate the 3/16" ID tubing and have a
means of sealing the fitting when the manometer is not
in use. Use silicone sealer or other sealant to seal
around the fitting to prevent leaks. The fitting should be
capable of being capped when the manometer tube is
removed. Sealing the fitting will prevent leaks that alter
the reclaimer’s separation efficiency. Air drawn into the
reclaimer will cause carryover of good media to the dust
collector.
10.4.8 Turn the exhauster ON. The negative (static)
pressure will move fluid in the tube.
10.4.9 To find the static pressure, add the number of
inches the fluid travels up one column to the inches the
fluid travels down the other column. Refer to the
example in Figure 6.
10.4.10 After taking the readings, replace the needle
protector. Close the manometer valves and store the
manometer in the original container in a clean area.
Note: If the manometer installation is permanent, the
manometer may remain on the reclaimer body after the
valves are closed.
11.0 PREVENTIVE MAINTENANCE
11.1 Debris Screen: Begin by checking the reclaimer
debris screen daily and adjust to weekly inspection if the
screen is empty. To clean, turn the exhauster OFF, open
the access door, and remove screen. Empty the screen
and replace it, making sure it is securely re-attached to
the inner cone.
11.2. Periodically check for wear on the reclaimer inlet
adaptor pipe, outlet vortex pipe, and flex hoses. Replace
as required.
11.3 Inspect wear plate or optional rubber liners
every two months. Replace liners when the rubber is
worn-through.
11.4 Inspect transition wear plate every two months.
Replace when the rubber is worn-through.
12.0 SERVICE MAINTENANCE
12.1 Replacing Reclaimer Wear Plate, Figure 7
12.1.1 Remove the reclaimer top plate, inlet adaptor
pipe, gasket and old wear plate. The wear plate is held
The manometer must be vertical when
taking pressure readings.
With the exhauster OFF,
slide the rule to align the
zero with the fluid level.
To obtain the static pressure reading:
With the exhauster ON, add the number
of inches the fluid travels up the
column, and the number of inches the
fluid travels down the other column.
The total is the static pressure reading.
In the example shown, fluid traveled up
the right column 1-3/4 inch,
and down the left column 1-3/4 inch.
Static pressure is determined by adding
the columns together. In the example,
the static pressure is 3-1/2 inches.

reclaimer; remove the screws to remove the wear plate.
Figure 7
12.1.2 Remove what remains of old caulking from the
reclaimer and top plate.
12.1.3 Insert the new wear plate into reclaimer inlet until
it is in position with the straight end at the reclaimer inlet.
Use locking pliers, clamps, board (2 x 4), or other means
where needed to pry the wear plate against the side of
the inlet and inner wall. Make sure the leading edge of
the wear plate is aligned with the reclaimer inlet and that
the top edge is even with the top of the reclaimer.
12.1.4 New self-drilling sheet metal screws are
provided with the wear plate and are match-drilled
through the old screw holes into the wear plate at each
screw hole location. Rearrange the clamp(s) as needed
to press the wear plate against the reclaimer wall when
installing screws through the old holes.
12.1.5 Reattach the top plate.
12.1.6 To avoid rapid wear, apply RTV caulk to fill gaps
at the seams on the top and bottom of the wear plate.
12.1.7 Reattach the inlet adaptor pipe, replacing the
gasket if worn, compressed or otherwise damaged.
12.2 Replacing Rubber Reclaimer Liners, Figure 8
The reclaimer must be designed to accept liners and
have a removable top. If the reclaimer is currently
unlined, begin at the installation note preceding
Paragraph 12.2.9.
12.2.1 Remove the flex hoses from the reclaimer inlet
and outlet.
12.2.2 Remove the bolts and nuts, securing the
reclaimer top, and then remove the top, top liner and
tube (inner cylinder) liner.
12.2.3 Grind the tack welds from the bottom of the tube
liner that secures the tube liner to the tube, then slide the
liner off the inner tube.
12.2.4 Remove the bolts located along the side of the
inlet, and remove the inlet baffle.
12.2.5 To remove the inlet-top liner, remove the self-
drilling screws securing it to the top of the inlet.
12.2.6 Wall liner and inlet-side liner are held in place
with self-drilling screws. From the outside of the
reclaimer, remove the screws, and remove the liner.
12.2.7 Inner cone liners and cone-ring liners are glued
onto the inner cone. Pull off the liners to remove them.
12.2.8 Remove old caulking and adhesive from the
weldment.
Installation Note: The numbers in parenthesis (-)
shown in Figure 8 and the applicable paragraphs, show
the recommended order of installation. When installing
the liners, make sure that seams are aligned. The final
assembly must be smooth and free of protrusions,
edges, and gaps. Any edges will disrupt the air flow,
causing wear, and affect the reclaimer’s media cleaning
efficiency.
12.2.9 (1st) Place the cone-ring liner on the inside of
the cone-ring; check fit and trim if needed. Apply
medium-set contact cement to the fabric side and install
the liner. Note: Follow the instructions provided with the
adhesive, some adhesives require covering both
surfaces to be cemented. Smooth out the liner to
eliminate air pockets.
12.2.10 (2nd) Place the cone liner in the cone with the
fabric side down, and check the fit; trim if necessary.
Follow the instructions provided with the adhesive and
apply medium-set contact cement to the fabric side, and
install the cone liner. Smooth out the liner to eliminate air
pockets.
12.2.11 (3rd) Position the inlet-side liner and inlet-top
liner to make sure they fit; trimming is occasionally
required. Align the inlet-side liner and inlet-top liner and
clamp them in place. Use a self-drilling screw at each
hole location in the weldment to secure replacement
liners. Note: To field install new, first-time inlet-side liner
and inlet-top liners, after clamping the liners, use self-
drilling screws at each liner corner to secure them.

12.2.12 (4th) Clamp the wall liner in place, making sure
it is flush with the top of the reclaimer body and the
cutout is aligned with the reclaimer inlet. Mark the wall
liner at the three bolt-hole locations for the inlet baffle.
Remove the liner and drill the bolt holes. Reinstall the
wall liner. Align the three bolt holes and temporarily
place bolts through the holes to hold it in place. Clamp
the liner, and while pushing the liner against the weldment,
secure replacement liners, with self-drilling screws at
each existing hole location. Note: To field install a new,
first-time wall liner, use self-drilling screws to secure it at
the seam and an inch or two from the top and bottom at
each quadrant. Remove the temporary inlet baffle bolts
after the liner is secured.
12.2.13 Apply silicone caulking to seal seams around
the inlet-side liner and reclaimer weldment, and between
the inlet-top liner and wall liner seam. Apply caulking at
the seams of the cone-ring liner and cone liner and
between the cone liner and wall liner. Wipe the caulking
smooth.
NOTICE
All seams between each liner must be sealed,
and all seams between the liners and reclaimer
weldment must be sealed. Voids will cause
premature wear.
12.2.14 (5th) Apply adhesive-backed strip gasket to the
edge of the inlet baffle that fits against the inner tube.
Install the inlet baffle; bolts should be installed from the
inside of the reclaimer to attach nuts from the outside.
12.2.15 (6th) Slide the top liner over the inner tube and
align the holes in the liner with those in the top. Note that
the holes around the inlet are spaced differently from the
others. Temporarily install a couple of bolts to maintain
the alignment.
12.2.16 (7th) Place the tube liner over the inner tube,
and use worm clamps to temporarily clamp the liner to
the tube. Align it so the seam is on the backside of the
baffle, as shown in Figure 8. Make sure the liner is tight
against the top liner, then tack the liner to the bottom of
the inner tube in three or four places. Remove the
clamps when the tube liner is secured.
12.2.17 Apply caulking to the seam on the tube liner,
and between the tube liner and top liner.
12.2.18 Apply caulking around the top edge of the wall
liner and inlet-top liner.
12.2.19 Align the reclaimer top assembly and lower it
into place being careful not to smear the caulking.
Secure the top bolts and inlet baffle bolts.
12.2.20 Working through the reclaimer inlet, wipe the
caulking seal smooth. Apply additional caulking to the
seam between the baffle and wall liner. Re-caulk any
voids.
12.2.21 Install flex hoses.
12.2.22 Allow time for the caulking to cure before
putting the reclaimer in service.
12.3 Transition Elbow Wear Plate
Figures 9 and 10
NOTE: If the M-Section® is short and light enough, and
surface-mounted, the wear plate may be replaced by
raising the transition end, otherwise remove the elbow
as follows:
12.3.1 Remove the bolts securing the top adaptor and
remove the top adaptor, as shown in Figure 9. Remove
the flex hose if necessary.
12.3.2 Remove the bolts securing elbow to the
transition and remove the elbow.
12.3.3 Remove the screws and wear plate from the
outside radius on the elbow.
12.3.4 Attach the new wear plate elbow.

12.3.5 Apply a bead of caulking to the top side of the
new wear plate as shown in Figure 10, and install the
elbow onto the transition. Apply new gasket material if
necessary.
12.3.6 After the elbow is securely attached to the
transition, apply caulking to the lower seam to ensure an
air tight seal.

12.3.7 Reattach the top adaptor, using new gasket
material if required.
13.0 TROUBLESHOOTING
13.1 Excessive media carryover
13.1.1 Dust collector damper open too far. Adjust static
pressure per Section 10.2.
13.1.2 Vortex cylinder out of adjustment. Adjust vortex
cylinder per Section 10.3.
13.1.3 Reclaimer or storage hopper door open or
leaking. Check doors and gasket for leaks. Air entering
the reclaimer at this point will cause media to be carried
into the dust collector. DO NOT operate unless all doors
are closed.
13.1.4 Flange gasket between the blast machine,
storage hopper, or reclaimer leaking. Check gaskets for
negative pressure leak.
13.1.5 Leak in reclaimer weldment. Check entire
reclaimer for leaks.
13.1.6 Media level too high. Load media per Section
9.0.
13.1.7 If using 180 mesh and finer media or very light-
weight media, the inlet baffle of the reclaimer may need
to be removed. Refer to Section 1.6.6.
13.1.8 Reclaimer debris screen blocked with debris.
Check screen basket daily.
13.2 Media buildup in M-Section®hoppers,
reclaimer not recovering media
13.2.1 Dirty dust collector filter cartridge(s). Refer to the
reverse-pulse dust collector manual to adjust pulse
pressure, pulse sequence, and changing cartridge(s).
13.2.2 Exhauster motor rotating backwards. The motor
should rotate as indicated by the arrow on the exhauster
housing. If it does not rotate in the proper direction,
lockout and tagout electrical power and switch the
motor leads as shown on the motor plate. Refer to the
system’s wiring schematic and Paragraph 6.3.
13.2.3 Dust collector damper closed too far restricting
air movement through the M-Section®. Adjust static
pressure per Section 10.2.
13.2.4 Blocked air inlet hopper. Air enters through the
hopper farthest from the transition elbow, Refer to
Figure 1. Blockage in the air intake restricts incoming air
and reduces air movement through the M-Section®.
Check for blockages.

13.2.5 Hole worn in flex hose between transition and
reclaimer inlet or between the reclaimer outlet and dust
collector inlet. Replace hoses and route them with as
few bends as possible to prevent wear.
13.2.6 Reclaimer door open. DO NOT operate unless
door is closed.
13.2.7 Obstruction in transition, flex hose, or any
segment before the reclaimer inlet. Remove hose and
check for blockage.
13.2.8 Exhauster paddle wheel worn. Check wheel for
wear.
13.3 Abnormally high media consumption
13.3.1 Media carryover, refer to Section 13.1
13.3.2 Media may be too fine or worn-out. Replace
media as necessary.
13.3.3 Using media that rapidly breaks down. If the
application allows for it, change to durable media.
13.3.4 Blast pressure too high for the media, causing
media to breakdown. If the application allows for it, lower
blast pressure.
13.4 Reduction in blast cleaning rate
Also refer to the blast machine owner’s manual.
13.4.1 Low media level reducing media flow. Check
media level and refill as necessary.
13.4.2 Reduced air pressure. This may be caused by a
malfunctioning regulator, a dirty filter element in moisture
separator, partially closed air supply valve, leaking air
line, or other air tools in use. Refer to the blast machine
owner’s manual.
13.5 Plugged blast nozzle
13.5.1 Damaged or missing reclaimer debris screen.
When the filter screen is damaged or not in place, all
media and blast cleaning by-products, such as paint
chips, scale etc. pass directly into the blast, blocking the
metering valve or nozzle. Check placement of the debris
screen.
13.6 Media bridging
13.6.1 Frequent bridging or blockages in the media
metering valve can be caused by damp media. Media
becomes damp by blasting parts that are slightly oily,
from moisture in the compressed air line, or from
absorption from ambient air.
13.6.2 To avoid contaminating media from the
workpiece, all parts should be clean and dry. If parts are
oily or greasy, degrease and dry them prior to blasting.
13.6.3 Moist compressed air may be due to a faulty
compressor that overheats or pumps oil or moisture into
the air line, too long an air line permitting moisture to
condense on the inside, or from humidity. Moisture
causes media to clump and inhibits free flow through the
blast machine metering valve. If the filter does not
remove enough moisture to keep media dry and flowing,
it may be necessary to install an air dryer or aftercooler
in the air supply line.
13.6.4 Absorption: Some media tends to absorb
moisture from the air, especially fine-mesh media in high
humidity areas.
