Manual No. 21309, Rev. J 01/19
4.1.2 Media loading:
With the exhauster OFF, add
clean, dry media by pouring it through the reclaimer
door. Do not fill above the hopper on the reclaimer.
Do
not pour media directly into the cabinet hopper, as
overfilling may occur.
Overfilling will result in media
carryover to the dust collector and possible blockage in
the conveying hose. Refill only after all media has been
recovered from the cabinet.
4.2
Media Unloading ‒ Figure 15
4.2.1
To empty the cabinet of media, turn ON the
exhauster and blow off the cabinet interior until all media
is recovered from the cabinet. Turn OFF the exhauster
and place an empty bucket or other suitable container
under the metering valve. Unscrew the plastic plug from
the metering valve, permitting media to flow into the
bucket. If media doesn't flow, it has caked; open the fill
door and stir media until it starts to flow. Before the
container becomes too heavy to easily handle, replace the
plug and empty the container. Replace the plug when the
reclaimer is empty or purge the hose(s), as noted below.
4.2.2
To purge the media hose, before replacing the
plug turn ON the exhauster, grasp the gun, and press
the foot pedal using the gun to blow off the cabinet
interior until the air from the gun and the cabinet are
clear. Turn OFF the exhauster and replace the plug.

Loading and Unloading Parts
WARNING
Use solid fixturing to hold heavy parts in place.
Do not remove lift equipment until the part is
adequately supported to prevent movement.
Moving heavy, unsupported parts may cause
them to shift or topple and cause severe injury.
This is especially important with the use of
turntables.
4.3.1
Load and unload parts through either door.
4.3.2
Parts must be free of oil, water, grease, or other
contaminants that will clump media or clog filters.
4.3.3
When blasting small parts or objects having small
pieces that could become dislodged and fall off, place an
appropriately sized screen over the grate (or under the
grate when frequently blasting small parts) to prevent
parts from falling into the hopper. If an object should fall
through the grate, stop blasting immediately and
retrieve it.
4.3.4
Close door; the door interlock system will
prevent blasting if either door is open.
4.4
Blasting Operation
WARNING
To avoid the inhalation of dust, which can
cause respiratory illness from short-term
ingestion or death from long-term ingestion:
Use the blow-off nozzle to blow media off
parts before opening doors.
After blasting, keep doors closed and
exhauster running until the cabinet is clear
of all airborne dust.
Always close cabinet, reclaimer, and dust-
collector doors before blasting. Keep all
doors closed during blasting.
Always wear blast gloves.
Stop blasting immediately if dust leaks are
detected.
4.4.1
Slowly open the air supply to the cabinet. Check
for air leaks on the initial startup and periodically
thereafter.
4.4.2
Turn ON the lights and exhauster. The ON/OFF
switch performs both functions.
4.4.3
Load parts.
4.4.4
Close door; the door interlock system will
prevent blasting if either door is open.
4.4.5
Adjust the pilot-pressure regulator to the
required blast pressure, per Section 5.1. The regulator is
located on the top-left side of the cabinet.
4.4.6
Insert hands into rubber gloves.
