Disassembly For Conversion
Assembly For Conversion
1. Disconnect air supply to unit and release tank pressure if any.
2. Loosen hose clamp and remove Flow Air Hose by pulling hose free
from barbed fitting on the Abrasive Outlet Manifold. Note: Clarke
and some other units have a swivel connection at the top end of
hose for ease of disassembly and a threaded 45° connection at the
Abrasive Outlet Manifold.
3. Remove Blast Nozzle Hose from Abrasive Outlet Manifold by removing hose clamp and pulling hose free from barbed fitting.
4. Loosen and remove the Abrasive Outlet Manifold and Ball Valve
assembly from bottom of tank. (Fig 1). Note: Some tanks including
ALC brand units have a 3⁄4” MNPT x 1⁄2” FNPT reducer fitting at the
tank bottom. Leave this in place.
5. Remove all shreds of thread sealing tape and inspect fittings and
threads for cracks or damage.
1. Remove protective plastic cap from male threads on top of Soda
Blast Conversion Assembly.
2. Using thread sealing tape, thread the assembly into the bottom of
the tank and tighten with a suitable wrench. Note: barbed fitting &
Clear Purge Hose should face forward (Fig.2). Note: Failure to properly seal or over tightening fittings can lead to component failure
which could result in sudden air pressure release and cause serious
injury.
3. Place the Flow Air Hose over the rear-facing Barbed Fitting and tighten existing hose clamp. Note: On some Clarke units; the Flow Air
Hose is directly threaded into the Abrasive Outlet Manifold on a 45°
angle. A 3/8” FNPT x 3/8” MNPT 45° fitting is included for this application and if so equipped; remove the rear-facing Barbed Fitting and
using thread sealing tape, replace it with the above 45° fitting.

IMPORTANT NOTE:
Soda Blasting Media is highly susceptible to moisture absorption which
will cause clumping and erratic operation. To insure proper function, it
is imperative to have an effective moisture filter and or desiccant system in the air supply immediately before the Air Inlet. Be sure to drain
any moisture captured in the moisture filter before and after each use.
Failure to do so may cause “caking” of media and complete blockage of
equipment.
Operation
1. Refer to the specific safety and operation information in the instruction manual included with your Pressure Blaster before continuing.
2. Carefully fill the unit per Blaster Instructions using a screen sifter and
funnel. Note: a suitable screen sifter such as an Eastwood #22022
must be used to capture any clumps present in the bag of media.
3. Close all four valves and connect the air supply. DO NOT EXCEED
125 PSI. For best results, begin with a blaster inlet pressure of 80
to 90 PSI. To avoid media clumping or caking, be certain to have a
clean, moisture free air supply that includes an effective moisture
filter or desiccant system.
4. Open the Inlet Air Supply Valve slowly while checking for leakage.
5. Slowly open the Throttling Valve (Fig. 3) to the 1⁄2 position while
checking for leakage. Note: This valve will require fine tuning to provide optimal media flow based on media formulation, air pressure
and desired volume.
6. Slowly open the Media Flow Valve to the full position while checking
for leakage.
7. You may now direct the nozzle toward your work and depress the
Nozzle Discharge Lever. Note: Some slow, pulsing discharges of
media can be expected until the flow begins.
8. Once a steady flow of media is observed, begin by holding the
nozzle 6” to 12” from the work surface at a 30° to 45° angle for best
results.
9. Hold the stream against the work until it abrades through the coating revealing an edge.
10. Use the stream as a “wedge” working at the edge to quickly remove
the coating.

11. At this point you can vary the position of the Throttling Valve (Fig.
3) from the initial 1⁄2 open starting setting to achieve an optimum
air/media ratio. Note: As there are many variables affecting the flow
such as media formulation, hardness of coating, air volume, air
pressure and atmospheric conditions, this process requires a bit of
“trial and error” by experimenting with distance, angle and throttle
position. You will quickly become proficient at determining the ideal
settings.
12. When refilling the tank becomes necessary, first shut off the Inlet
Air Supply Valve, The Throttle Valve and The Flow Valve. For safety,
disconnect the air supply. Next, open the Inlet Air Supply Valve to
release all tank pressure. You may then open the Tank Filler Cap and
refill per filling instructions in your users manual.
13. It is strongly advisable to drain all unused media when completing
work as any moisture present in the tank will drain to the bottom
of the tank and can create a solid “cake” with the media, requiring
complete disassembly of the apparatus at the bottom of the tank.
14. To drain unused media from the tank, place the open end of The
Clear Purge Hose into a suitable vessel such as a large bucket or
box with closed seams and cover with a blanket. Using extreme
care, slowly open the Purge Valve and direct the stream of media
into the vessel.

Troubleshooting
Work Area Prep and Cleanup
1. The most comFigure 4
mon problem
encountered
with Soda Blasting is clumping
of media due
to moisture
contamination. If media
stops flowing,
Purge Valve
stop all work
and “burp”
(quickly open
and close) the
Purge Valve
allowing a minimal discharge
of media from
Media Flow Valve
the Clear Purge
Hose. Be certain to direct the discharge to a safe area. Placement
of the hose in a cardboard box covered with a blanket is strongly
recommended.
2. If a purge fails to restore flow, stop all work and close the Throttle
Valve (Fig. 3) fully. You can then depress the Nozzle Discharge Lever
several times which will discharge a quantity of media under tank
pressure clearing the clumping.
3. It is strongly advisable to drain all unused media when completing
work as any moisture present in the tank will drain to the bottom of
the tank and can create a solid “cake” with the media. Should this
occur, it will require complete disassembly of the apparatus at the
bottom of the tank for cleaning.
4. If results become erratic or undesirable, remember that there are
many variables affecting the flow such as media formulation, hardness of coating, air volume, air pressure and atmospheric conditions, this process requires a bit of “trial and error” by experimenting
with distance, angle and throttle position. By adjusting Throttle Valve
(Fig. 3) position between 1⁄2 and full open and varying the distance
of the nozzle to work surface along with the angle, optimal performance can quickly be restored. Refer to steps 8 through 11 in the
Operation section for more information.
1. Soda Blasting generates a considerable amount of fine bicarbonate
of soda dust. If working outdoors, be aware of wind direction, open
windows, vegetation, vehicles, pets, people and property. It may be
helpful to place a fine mist, garden hose lawn sprinkler downwind of
the blasting site to suppress dust generation.
2. It is best to cover the work area under and surrounding the vehicle
or object to be stripped with a 3 mil or thicker plastic sheet material
to assist in cleanup. You may also wish to tape up window seals and
other areas to keep unwanted dust out of a vehicle.
3. Bicarbonate of Soda itself is virtually harmless to the environment
however, in higher concentrations; it may cause browning of vegetation. Care should be taken to avoid depositing excess soda on plant
life.
4. When, finished, the plastic sheeting with the used soda media can
be rolled up and disposed of, reducing sweep up time. The remainder should be swept up and disposed of. Any remaining soda
residue is water soluble and can be hosed away. Important Note:
Although the Bicarbonate of Soda blasting media itself is safe in
most situations, appropriate care should be taken when using or
disposing as any removed paint or coating can contain some levels
of hazardous materials such as lead, zinc chromate, etc.
5. The use of a fine water misting device such as Eastwood’s #21502
Wet Sand Sprayer directed at the deflected material while blasting
greatly reduces the resulting dust cloud.

Helpful Tips
• Soda Blasting leaves behind a thin protective film which, if left
untouched, will prevent surface rust from forming on bare steel
surfaces for up 6 weeks or even longer if stored in a dry, protected
area. This film must be removed before painting by wiping down
with water dampened Microfiber cloths or suitable lint-free towels. It
is best to soak the cloth, wring out excess water, wipe off soda residue, rinse often and immediately follow up with a dry lint-free towel.
• Any soda media left in body seems or crevices can be removed with
a small shop vacuum and a fine tipped blow gun. Be sure to wipe
surrounding areas as described above.
• To prevent flash rust or oxidation from appearing on metal surfaces
after water wipe down but before painting, treat surfaces with Eastwood Fast-Etch, #19416Z.
