DCM-161 MINI TUMBLE BLAST CABINET
Page 3
1.8.6 Fine-mesh
Media:
In most cases media finer
than 180 will carryover to the dust bag.
1.8.7 Lightweight Media:
In most cases plastic
media and most agricultural media are not
recommended with the tumble cabinet. They are usually
too light for suction blast applications, and may bridge in
the barrel and hopper.
1.9
Compressed Air Requirements
1.9.1
Compressed air consumption for the cabinet is
approximately 17 cfm at 60 psi.
1.9.2
The filter/regulator at the air inlet connection,
reduces condensed water from the compressed air. Its
use is especially important in areas of high humidity, or
when fine-mesh media are used. Moisture causes media
to clot and inhibits free flow through the feed assembly.
If moisture problems persist, an air dryer may be
required.
1.10 Electrical
Requirements
1.10.1
The system requires 115-VAC, 1-Ph, 60-Hz,
with 15 Amps service. A power cord is supplied. No
additional wiring is required.
Do not use electrical adaptors that eliminate the
ground prong on 115 volt plugs. Doing so can
cause injury from electric shock, and
equipment damage.
2.0 INSTALLATION
2.1
General Installation Notes
2.1.1
Place the cabinet in a convenient location where
compressed air and electrical service are available.
Allow full access to the door and service areas. Leave
enough clearance around the dust bag for it to inflate
without interference.
2.2
Connect Compressed Air Supply Line
2.2.1
Install an isolation valve at the air source to
enable depressurization for service. Connect a 1/2 inch
or larger air line from the air source to the air
filter/regulator.
If twist-on type air hose couplings are used,
they must be secured by safety pins or wires to
prevent accidental disconnection while under
pressure. Hose disconnection while under
pressure could cause serious injury.
WARNING
2.3
To prevent static electricity build up, attach an
external grounded wire from an earth ground to the
grounding lug on the rear of the cabinet.
2.4
Attach the dust bag to the exhauster outlet.
Secure using the clamp provided.
2.5.
Plug the cabinet power cord into a grounded,
115 volt outlet.
3.0 OPERATION
3.1. Control
Functions
3.1.1. Timer:
Sets duration of the blast cycle and
starts the blasting. Blasting automatically stops when the
timer times out.
WARNING
3.1.2 Door
Interlock:
When the door is open the blast
gun is disengaged, preventing blasting.
3.2
Media Loading and Unloading
3.2.1 Media
Loading:
With the timer off, add clean
dry media, by pouring it through the front door. Maximum
media capacity is approximately 1/10 cu. ft. (3 quarts).
Do not overfill.
3.2.2 Media
Unloading:
To empty the cabinet of
spent media, turn off the exhauster and place an empty
container under the media drain plug. Unscrew the plug,
and tilt the cabinet as needed for media to flow into the
container. If media doesn't flow, it has caked. Open the
fill door and stir media until it starts to flow. Replace the
plug when empty.
3.2.3
Use a vacuum and thoroughly purge the cabinet
of media when changing media type, especially when
changing from coarse media to fine, or when changing
from hard media to soft.
