1.6 Compressed Air Connection

IMPORTANT
To operate properly, your ProFormerTM system requires clean, dry air. Moisture
or oil in the compressed air supply can contaminate the abrasive, which can
prevent it from flowing freely and cause inefficient blasting. Though your
system is equipped with a general-purpose filter to remove small amounts of
condensed water and oil from compressed air supply, this filter is not designed
to clean grossly contaminated air.

Step 1: Using the following two charts, determine the proper air volume needed for

your ProFormer

Step 2: The volume of air required for efficient operation of your system depends on
the size of the nozzle you are using and the desired blast pressure. The chart lists the
minimum air requirements in SCFM for various nozzles and pressures.

¼” nozzle, 1/8” air jet 12 17 21 26
5/16” nozzle*, 5/32” air jet 19 27 34 42
3/8” nozzle, 3/16” air jet 29 39 50 62
7/16” nozzle, 7/32” air jet 38 52 66 80

3/16” nozzle* 22 30 38 45
¼” nozzle† 41 54 68 81
* Standard nozzle
† 3/4” blast hose option is recommended to reduce blast hose wear.

Step 3: Use the chart below as a guide to determine the size of the compressed air line
needed for your ProFormer
available, the supply air line to the system must be large enough to prevent friction
losses that create pressure drops which will reduce blast pressure and efficiency.

Step 4: The customer is to provide and install an air supply shut off valve. This
should be a three-way valve that will bleed off all trapped down stream compressed air
from the cabinet. The valve must also be able to be locked when closed.

1.7 Earth Ground

An Earth Ground stud is provided at the bottom right side on the enclosure back wall.
It is important to connect the ProFormer

™

system to an Earth Ground to bleed off
static electricity which may be generated while blasting. The Earth Ground may also
reduce the discomfort an operator may experience when static electricity is
discharged.

The Earth Ground conductors may be insulated or bare. Note that defects are more
easily detected during visual inspections of bare conductors.

The minimum wire size is dictated by mechanical strength rather than current
carrying capacity. Flexible conductors should be used when frequent connecting and
disconnecting of the Earth Ground is anticipated.

1.8 Installation Check

Step 1: Check that all pipe and hose connections are tightly fastened and air tight.
Check that all safety pins are properly installed in all quick couplings.

Step 2: Check that all electrical box covers are securely installed. Turn on the plant
compressed air supply to the system.

Step 3: Check that the dust drum under the dust collector has been installed
properly. It must be sitting squarely on the dust drum platform and centered under
the cover. Set the dust collector pulse pressure regulator to 40 psi. Check that the
optional fan silencer is fully opened.

Step 4: Turn the cabinet snap switch to the On position. The cabinet lights will
illuminate and the dust collector fan will start. Check that the fan is rotating in the
correct direction.

CAUTION
Disable and lock out power sources before performing service or maintenance
work. Do not look into the fan outlet to determine the correct motor rotation.
Check that the fan exhaust is clear of tools and free of debris before checking
fan rotation. To avoid personal injury, stay clear of the fan exhaust.

Step 5: Set the blast air pressure regulator to the desired pressure. The blast
pressure may be set as low as 20 psi, but do not exceed 125 psi.

Step 6: Insert both hands into the cabinet gloves and firmly grasp the suction gun or

pressure nozzle. Step on the foot treadle. The blast should start. After a few seconds,
the airflow from the nozzle will stabilize. Blast will stop when the foot treadle is
released.

Step 7: If applicable, press each dust collector pulse button once with the dust
collector on to insure pulse function.

The optional Photohelic control pulsing of the dust collector filters is automatic.
Adjust both red needles to below zero psi. The black needle must rise above both red
needles to activate the pulse. An increase in the gauge zero adjustment may be
required to test this function. After a successful test, the gauge setpoints should be

Page 11

Empire Abrasive Equipment Company

set at a value of 2 psi for minimum, and 4 psi for the maximum pressure. When the
system is off, reset this gauge to zero.

Step 8: Turn the cabinet snap switch to the Off position. The cabinet lights will
extinguish and the dust collector fan will stop. The ProFormer

™

system is now ready

for media loading and part processing.

2.0 Equipment Operation

2.1 Loading Media

There are two methods for loading media into the ProFormer
the media level in the system before adding additional media. See section 4.1 for
Media Selection and Use.

The suction system hopper should be filled to the bottom of the reclaimer screen. The
pressure system vessel may be filled to the base of the sealing plunger.

Total media capacity by weight for the suction and pressure ProFormer
shown for popular media in the table below.

Method 1: With the cabinet switch OFF, media may be loaded through the removable
reclaimer access door. The reclaimer is located inside the left component access door.
After loading the media, reinstall the reclaimer door and insure an airtight seal.

Method 2: With the snap switch ON and the dust collector running, load media
through the media load station inside the right cabinet door. Place the appropriate
quantity of media between the cabinet cone and media load station baffle. The system
will slowly add the new media.

Glass Beads Aluminum Oxide Steel Shot or Grit

Suction 10 lb. 15 lb. 25 lb. 5 lb.

Pressure 75 lb. 100 lb. 200 lb. 30 lb.

IMPORTANT
Be careful not to overfill pressure systems. Overfilling will cause malfunction
and premature wear. See section 5.1 Daily Maintenance.

CAUTION
If your application requires aggressive media, such as aluminum oxide, garnet, or
steel grit, it is recommended that you use optional heavy-duty ducting,
reclaimer lining, and DI-CARB or BORON nozzles to prevent premature wear.

Empire strongly recommends using boron carbide nozzles when blasting with
Aluminum oxide, which is the most abrasive media.

If these options are not included with your system, they can be added. Optional
Rubber curtains for interior cabinet surfaces are also available. Consult your
Empire distributor for details.

2.2 Start Up

Step 1: Check that all pipe and hose connections are tightly fastened and air tight.
Check that all safety pins are properly installed in all quick couplings.

Step 2: Perform maintenance checks per section 5.0 Maintenance.

Step 3: Check that the dust drum under the dust collector is empty and has been

installed properly. It must be sitting squarely on the dust drum platform and centered
under the cover. The dust drum and cover must create an air tight seal.

Step 4: Turn on the plant compressed air supply. Turn the cabinet snap switch to the
On position. The cabinet lights will illuminate and the dust collector fan will start.

Step 5: Place the parts to be blast treated inside the blast cabinet. The parts must be
free of oil, grease, and moisture. Close and latch the cabinet load doors.

Step 6: Set the blast air pressure regulator to the desired pressure. Recommended
blast pressure ranges for various media types are listed in the table in section 4.1
Media Selection and Use. Do not exceed 125 psi blast pressure.

2.3 Blasting

Step 1: Insert each hand into a cabinet glove and grip the suction gun or pressure
nozzle assembly firmly. Aim the nozzle at the part to be blast treated.

Step 2: Step on the foot treadle to start the blast. After a few seconds the abrasive
flow will stabilize and you will be ready for blasting.

Step 3: Do not pump the foot treadle. It will decrease blast efficiency and cause
premature wear of system components.

Step 4: Hold the gun or nozzle at a 90-degree angle to the part at a distance that
produces the fastest results. This distance may vary from 3 to 18 inches, depending
on the work piece and the desired finish. See section 4.2 Blast Pattern.

Step 5: During the blasting process, periodically check the Minihelic pressure gauge
located above and to the right of the cabinet window. This gauge indicates the
condition of the filters. If the gauge pressure is 4 psi or greater, clean the filters as
outlined in section 2.4 Dust Collector Cartridge Cleaning.

Step 6: The reclaimer screen will require periodic cleaning. The frequency of cleaning
will depend on the volume of debris produced.

Step 7: For pressure systems, all the media in the pressure vessel will be used up
after an extended period of blasting. The operator must release the foot treadle to stop
the blast and depressurize the vessel. After a wait of approximately 2 minutes, media
will fill the pressure vessel and blasting can resume.

Step 8: When blasting of the part is complete, blast additional parts or follow the
instructions in section 2.5 Equipment Shut Down to shut the system down.

Page 13

Empire Abrasive Equipment Company

2.4 Dust Collector Cartridge Cleaning

IMPORTANT
Never pulse clean the filters when the system is off. If dust is visible exiting the
dust collector fan housing, stop blasting and service the collector.

Pushbutton Control: During the blasting process, periodically check the Minihelic

pressure gauge located above and to the right of the cabinet window. This gauge
indicates the condition of the filters. If the gauge pressure is 4 psi or greater, the
filters must be cleaned. Press and release one pushbutton which will clean one of the
cartridges. Wait 10 seconds. Press and release the other pushbutton which will clean
the other cartridge. Continue this process alternating pushbuttons until the pressure
is reduced to 2 psi.

Photohelic Control Option: This option pulse cleans the dust collector filters
automatically when they need cleaning. The gauge high limit red needle must be set
at 4 psi as the maximum operating limit. The gauge low limit red needle must be set
at 2 psi as the minimum operating limit. The pulse pressure must be set at 40 psi.

IMPORTANT
Always use proper safety and protective equipment when disposing of collector
waste. Dispose of this waste properly.

WARNINGS
Explosive Dust: Explosive dust is generated from blast media, removed coatings
and substrates. An extreme concentration of dust may combust if ignited by
spark or flame. As a precaution, clean the system and empty the dust collector
often. Change media that has excessive dust concentration.

Emptying the Dust Collector: Always wear an appropriate dust mask when
emptying the dust collector and changing filters. Empty the dust collector daily.

2.5 Equipment Shut Down

Step 1: Release the foot treadle. The blast will stop. Remove the blast treated parts
from the blast cabinet.

Step 2: Check the Minihelic pressure gauge for the condition of the duct collector
filters. If the gauge pressure is 4 psi or greater, the filters must be cleaned. Press and
release one pushbutton which will clean one of the cartridges. Wait 10 seconds.
Press and release the other pushbutton which will clean the other cartridge. Continue
this process alternating pushbuttons until the pressure is reduced to 2 psi.

Step 3: Turn the cabinet snap switch to the Off position. Empty the dust collector
waste drum. Replace the drum squarely on the dust drum platform and centered
under the cover. The dust drum and cover must create an air tight seal.

3.0 Equipment Adjustments

3.1 Suction System Media Flow Adjustment

The ProFormer
control the flow of media to the suction blast gun. The regulator is located at the
bottom of the storage hopper assembly inside the left component access door.

The amount of media entering the hose is controlled by how far the media hose is
inserted into the regulator. For normal operation, approximately ½ of the air inlet port
is blocked by the media hose. This may vary slightly when changing media size nozzle
size, and/or blast pressure.

To find a uniform media flow, loosen the thumbscrew and slide the media hose into
the SAR-2 regulator to increase and withdraw the hose to decrease media flow at the
nozzle. To determine if media is flowing, look through the media regulator air inlet
while the gun is operating. Listen for the sound of the blast to be smooth and
constant.

™

suction blast system is equipped with the SAR-2 media regulator to

3.2 Pressure System Media Flow Adjustment

The ProFormer
Regulator which is installed at the bottom discharge port of the pressure vessel. By
rotating the T-handle, media flow through the regulator and out of the blast nozzle
may be adjusted.

Step 1: Rotate the T-handle counter-clockwise until there is no resistance. Reverse
direction and make three full turns of the handle.

Step 2: As the T-handle is turned clockwise, the media flow through the regulator will
be reduced. While the system is blasting, make final adjustments in ½ turn, ¼ turn,
or 1/8 turn increments.

Optimum and most efficient blast is when the media exiting the blast nozzle is
just visible. Sure-Flo® Media Regulator adjustment may vary slightly when
media size, nozzle size, and/or blast pressure is changed. There are occasions
when blast pressure, media, and nozzle size requirements will not allow the Sure­Flo® Media Regulator to be properly adjusted to the desired media flow rate.
Refer to the tag attached to the regulator T-handle for additional instructions
and see section 4.0 Suggestions for Efficient Blasting for helpful hints.

3.3 Reclaimer Adjustment

All ProFormer
retained by the reclaimer. The reclaimer is supplied with a “tune-able” secondary air
adjustment. When the band is properly adjusted reusable media will be returned to
the media storage hopper. Unwanted dust and broken down media (fines) will be
removed from the system and conveyed to the dust collector. See Figure 6.

Empire’s reclaimer design has vertical slots with a solid tuning band. The original
ProFormer

Fine tuning adjustments of both reclaimers are similar. Just remember to move the
band in the direction of the reclaimer slots; horizontal slots rotate the band, vertical
slots slide band up or down.

The tuning band is joined at both ends by a bolt and wing nut that must be loosened
before the band can be adjusted. The slot pattern around the reclaimer body has one
slot omitted. The joined ends of the tuning band must be located over the area of the
omitted slot.

Dust collectors require a coating of dust on the filter cartridges to achieve
maximum filter efficiency, also known as “seasoning”. The filters are seasoned
when the static pressure reading on the collector gauge is 2 or greater.

Step 1: Start with no reclaimer slots visible. Adjust the band in one direction until

1/16” of opening is created between the band and reclaimer slots.

Place a reference pencil mark on reclaimer body (and a corresponding reference
mark on the tuning band if horizontal slots).

Step 2: Operate the blast system for at least one hour.

Step 3: Turn the cabinet snap switch to OFF.

Step 4: Inspect the dust collector waste drum for reusable media.

Step 5: If no media is found in the waste, adjust the tuning band to expose 1/16”

more reclaimer body slot area.

Step 6: Make a new reference mark on the reclaimer body.

Step 7: Repeat Steps 2 through 7 until a small amount of media is found in the dust

collector waste. Adjustment is complete.

™

reclaimers can be adjusted to control the average size of media

™

reclaimers have horizontal slots in both the reclaimer and tuning band.

NOTE

HELPFUL HINT

Page 16

Empire Abrasive Equipment Company

NOTE
As a new system is used, the filters become coated with dust, “seasoned” and the
airflow in the recovery system will decease to the normal operating rate. This
will affect previous reclaimer tuning band adjustments.

If visibility becomes poor inside the cabinet when blasting, there is too much dust
mixed with the blast media. The reclaimer tuning band should be re-adjusted.

Follow Step 2 though 7.

NOTE
For systems with large quantities of dust mixed with blast media, all dust and
media should be removed from the system and new media installed.

Step 8: If more than a small amount of media is found in the dust collector waste,
additional reclaimer tuning band adjustment may be required. Follow Steps 9
through 13.

Step 9: Adjust the tuning band back to the previous reference mark on the reclaimer
body, reducing the opening between the reclaimer and the band.

Step 10: After operating the blast system for at least one (1) hour, turn the cabinet

power switch OFF. Inspect the dust drum waste for reusable media.

Step 11: If no media is found in the waste, adjust the tuning band to expose 1/16”
less reclaimer body slot area.

Step 12: Make a new reference mark on the reclaimer body.

Step 13: Repeat Steps 8 through 13 until a small amount of media is found in the

dust collector waste. Adjustment is complete.

The schematic diagrams in Figure 6 illustrate:

(1) the basic operation of the system.
(2) the air and media flow before and after blasting.

Page 17

Empire Abrasive Equipment Company

Figure 6. Blast and Recovery Operation

IMPORTANT
An insufficient volume of secondary air entering the reclaimer will cause dust to
accumulate with the “good” media in the storage hopper or pressure vessel.
This accumulation leads to inefficient blasting. Conversely, too much secondary
air will cause useful media to be carried to the dust collector and be wasted.

To avoid these conditions, adjust the tuning band to meet your specific blasting
requirements. When your system is new, it will be necessary to readjust the
tuning band periodically until the filters are “seasoned”.

4.0 Suggestions for Efficient Blasting

4.1 Media Selection and Use

Proper media selection strongly influences the efficiency of your blasting operation.
Your choice of media depends on the kind of job to be done (cleaning, deburring,
smoothing sharp edges, paint removal, preparation for coatings, etc.) The size of the
media depends on the results you need.

Fine media results in more impacts per second over a given area. Therefore, fine
media is preferred for easy blasting jobs, such as the removal of light rust from steel.

Large media results in fewer impacts, but each impact has more force, so that large
media is more suitable for difficult jobs, such as removal of mill scale. Sometimes
large and find media may be combined for optimum results.

The chart below lists the range of media recommended for each ProFormer
System. Certain media, such as sand and slag, are not to be used in ProFormer
cabinets, both for health reasons and because they pulverize on impact and cannot be
recirculated.

Spherical media, such as glass beads, are used for general purpose cleaning and
finishing where a satin-like finish is desired with little dimensional change. Glass
beads are effective when used with pressures in the 20 to 60 PSI range. Above 60 PSI,
excessive bead breakdown will occur.

Angular aggressive media, such as aluminum oxide, steel grit, and garnet generally
provide faster cleaning and produce a less-polished finish compared to glass beads.
Aluminum oxide and steel grit are suitable for use at pressures up to 100 PSI. Garnet
breaks down quickly at pressures greater than 40 PSI.

Walnut shells or plastic are sometimes used for delicate parts, paint removal, or when
a polished finish is required. Pressures from 20 to 100 PSI may be used with these
media, depending on the application.

When changing from one type of media to another, clean the cabinet interior and
media hoses thoroughly to avoid cross contamination.

Page 19

Empire Abrasive Equipment Company

CAUTION
If your application requires aggressive media, such as aluminum oxide, garnet, or
steel grit, it is recommended that you use optional heavy duty ducting,
reclaimer lining, and DI-CARB or BORON nozzles to prevent premature wear.

Empire strongly recommends using boron carbide nozzles when blasting with
Aluminum oxide, which is the most abrasive media.

If these options are not included with your system, they can be added. Optional
Rubber curtains for interior cabinet surfaces are also available. Consult your
Empire distributor for details.

4.2 Blast Pattern

The size of the effective blasting pattern varies with the size, type and length of the
nozzle, blast air pressure, and the nature of the work piece. Use the following chart
and diagram as a guide, but be aware that the approximate pattern diameters can
only be determined by considering each case individually.

Blast Pattern Diameter at Distance Listed

4.3 Changing the Media

When changing from one type or size of media to another, it can be extremely
important to clean out the blast and recovery hoses, storage hopper, pressure vessel,
and the cabinet interior thoroughly to avoid contamination of the new media.

IMPORTANT
Always use proper safety and protective equipment when disposing of collector
waste. Dispose of this waste properly.

Suction System

Step 1: Turn the ProFormer

and locate the reclaimer, media storage hopper, and SAR-2 media regulator.

Step 2: Using proper safety and protective equipment, place a container, such as a
bucket, directly under the storage hopper and SAR-2 regulator. Loosen (do not
remove) the 7/16” nut at the bottom of the regulator plug. Pull down on the plug
removing it from the regulator. This will allow the media to empty from the storage
hopper into the container.

Step 3: Turn the ProFormer
Insert each hand into a cabinet glove and grip the suction gun firmly. Aim the nozzle
toward the back of the blast cabinet and press the foot treadle. Blast for 30 seconds
to remove all media from the suction hose and gun assembly.

Step 4: Release the foot treadle. Using proper safety and protective equipment, open
one of the part loading doors and use the Blowoff gun to remove the media from ledges
and surfaces into the cone for recovery.

Step 5: Turn the ProFormer
SAR-2 drain plug, and close the reclaimer door. Dispose of all waste properly.

Step 6: The system is ready for new media. Refer to section 2.1 Loading Media,
section 3.1 Suction System Media Flow Adjustment, and section 3.3 Reclaimer
Adjustment.

Pressure System

Step 1: Turn the ProFormer

and locate the reclaimer, media storage hopper, and pressure vessel.

Step 2: Adjust the T-handle of the Sure-Flo® grit valve counter clockwise, fully
opening the regulator. Close the 1” ball valve (choke valve) located on the pressure
vessel pipe string assembly. Fully open the reclaimer tuning band.

Step 3: Turn the ProFormer
pressure nozzle and nozzle washer from the end of the blast hose. Place a container,
such as a bucket, inside the blast cabinet. Place the blast hose inside the container
and close and latch the part loading doors.

workers environment, and activate the blast.

Step 1: Turning the system snap switch on energizes the interlock solenoid valve,
permits air to enter the control air line to the foot treadle, illuminates cabinet lights
and start the fan motor.

Step 2: The operator steps on the foot treadle opening a three way control air valve.
Air enters the door interlock supply tubing continuing to the door air jets. If the part
load/unload doors are closed, latched, and door air jets are sealed, the control air
lines pressurize and open the main blast air valve (and the pressure systems exhaust
valve to close). The opening of the main air valve starts the blast.

Step 3: When the operator removes his foot from the foot treadle, the three way air
valve close, shutting off air to the controls, and exhausting all down stream air. The
control air line pressure bleeds from the door interlock supply tubing, main blast air
valve (and the pressure system exhaust valve). This permits the main blast air valve
to close (and the pressure system exhaust valve to open) stopping the blast.

Step 4: When a part load/unload door is opened, the pad covering the door interlock
air jet is unseated. When the foot treadle is pressed with a door open, control air
bleeds from the door air jet opening, preventing the control circuit from pressurizing.
The main blast air valve will not open, and blasting will not occur.

system uses a patented pneumatic control circuit to protect workers,

Page 22

Empire Abrasive Equipment Company

The following schematic diagrams illustrate the pneumatic control circuits for suction
systems (Figure 8A) and pressure systems (Figures 8B). For each system type, the
cabinets are shown in blasting and non-blasting modes (shaded pipe is pressurized).

Figure 8A.

Page 23

Empire Abrasive Equipment Company

Figure 8B.

Page 24

Empire Abrasive Equipment Company

The following drawings show media flow through a typical pressure system and are
provided to help you understand how to maintain the media at the proper level.

Pictured at right is a fully charged system with the vessel depressurized (no blasting).
Note that the media fills the pressure vessel but that there is not media in the storage
hopper.

Figure 9. Before Blasting

When blasting starts, the vessel pressurizes, the media impacts the part being blasted,
and reusable media is recovered and accumulates in the storage hopper. Continuous
blasting time is limited by the type and amount of abrasive in the in the vessel when
blasting starts (normally 8 to 15 minutes with a fully charged 1 cubic foot vessel,
depending on nozzle size and blast air pressure). Each time the operator stops
blasting, the vessel de-pressurizes and the sealing plunger drops. Media in the
storage hopper flows into the vessel. If blasting is stopped long enough (usually 1-2
minutes), all media in the storage hopper will transfer into the pressure vessel.

Figure 10. During Blasting

Page 25

Empire Abrasive Equipment Company

Thus, you can determine the amount of media in the vessel in either of two ways: (1)
note how much continuous blast time you can achieve with a fully charged vessel and
compare this with your current continuous blast time; or (2) stop blasting, open the
reclaimer door, and visually determine the media level by looking into the top of the
vessel.

Figure 11. After Blasting

Overfilling pressure vessels will cause improper operation and premature wear. Allow
sufficient time after blasting for the pressure vessel to refill (2 minutes). When the
pressure vessel is filled, check to see if any media has remained in the storage hopper,
indicating that the vessel is overfilled, the sealing plunger may not seat tightly when
you start blasting.

See section 5.3 Storage or Temporary Non-Use for instructions on how to empty the
pressure vessel.

Refer to section 2.1 Loading Media for instructions to add media.

4.5 Helpful Hints for More Efficient Blasting

The efficiency of your blasting operation depends on four factors:

1) Equipment selection

2) Media selection

3) Operating procedures

4) Maintenance

With the help of your Empire Distributor and/or Empire factory representative, you
now own equipment that will properly meet your blasting requirements.

You can select the proper media, operating procedures, and maintenance steps by
following the recommendations in this manual. If you need more information about
any aspect of your machine’s operation or the blasting process, contact your local
distributor or the factory.

The following measures will also help you improve the efficiency of your blasting
operation:

Step 1: To accomplish more in less time, use the largest nozzle practical for your
operation. Of course, nozzle diameter may be limited by the amount of compressed air
available, but an increased volume of compressed air is often justified by reduced
labor costs. Also, if you are blasting small parts, it doesn’t make sense to use a big
nozzle, as most of the blast pattern will be overspray.

Step 2: For faster cleaning, use the highest pressure practical for your operation.
Maximum pressure for a given operation is limited by type of media (e.g. glass beads
can break down rapidly above a certain pressure) and amount of material which must
be removed from the workpiece.

Step 3: If you are blasting small parts, it may be more efficient to manipulate the part
with tow hands and use an optional fixed nozzle holder.

Step 4:

Never underestimate the importance of clean, dry air.

problems are traceable to the lack of clean dry air than any other single factor. If the
supply air is not clean and dry, media quickly becomes contaminated, causing flow
problems, which wastes media and leads to excessive operator downtime.

5.0 Maintenance

5.1 Daily Maintenance

Step 1: Turn the cabinet snap switch on.

Step 2: Remove the accumulated dust from the dust collector drum and the debris

from the reclaimer screen.

Step 3: Check the condition of the media. If the media is contaminated or broken
down into dust, thoroughly clean the inside of the cabinet and recovery system and
reload with new media. See section 2.1 Loading Media.

Step 4: Adjust the reclaimer tuning band if you observe a dusty condition when
blasting. See section 3.3 Reclaimer Adjustment.

Step 5: Check the media level. For optimal operation, the media level should not drop
below one-half the recommended capacity.

A. The media level in suction systems can be observed in the media storage

hopper.

B. The media level in pressure systems can be observed by looking through the

optional sight glasses or the reclaimer door down into the top of the vessel.
When the vessel is de-pressurized, the sealing plunger must be visible. Add
media until just visible below the sealing plunger.

Step 6: Check light bulbs and gloves. Replace as required.

Step 7: Open the manual drain on the general-purpose filter in the cabinet pipe string

and drain any accumulated moisture and oil. Close the drain and dispose of the
waste properly.

Step 8: All quick coupling connections must be equipped with safety pins. Inspect all
couplings and blast hoses daily for splits, bubbles, soft spots, etc. Screws should be
flush with coupling surfaces. Tighten screws, if necessary.

5.2 Weekly Maintenance

CAUTION
If your application requires aggressive media, such as aluminum oxide, garnet, or
steel grit, it is recommended that you use optional heavy duty ducting,
reclaimer lining, and DI-CARB or BORON nozzles to prevent premature wear.

Empire strongly recommends using boron carbide nozzles when blasting with
Aluminum oxide, which is the most abrasive media.

If these options are not included with your system, they can be added. Optional
Rubber curtains for interior cabinet surfaces are also available. Consult your
Empire distributor for details.

Step 1: Repeat the daily maintenance procedures.

Step 2: Inspect all media-carrying hoses for wear by feeling along the length of the

hose for soft spots. Hoses with soft spots should be replaced.

Step 3: Check the nozzle for wear. When the nozzle is worn 1/8” oversize, replace it.
A drill bit can be inserted into the nozzle to check its size.

Step 4: On suction systems, check the air jet for wear.

Step 5: Loosen the set screw in the side of the gun body and remove the air jet. See

Figure 13.

Step 6: If the air jet shows wear, rotate it 90° and reinsert it into the gun.

Step 7: Re-tighten the set screw.

If an air jet is allowed to wear completely through, it will cause premature wear
of the gun body and nozzle.

Step 8: Check the nozzle adapter and gun body for wear. Replace if necessary.

Step 9: Check the window gaskets for leaks. Replace if necessary.
