6.0 CUBIC FOOT C-SERIES BLAST POT
Operating Instructions (Figure 3)
During use:
• Fill Blast Pot through hole (A) in top of Blast Pot. Do not overfill, the capacity of the Blast Pot
is 6 cubic feet of media.
• To start/stop media blasting, follow instructions in the remote control system (1) operator’s
manual.
• Monitor remote control system components per operator’s manual.
After use:
• Empty media from Blast Pot when blasting is concluded for the day.
• To remove media, place Metering Valve (3) in the FULL OPEN position. Place Choke Valve (2)
in the OFF (shut) position. Remove Blast Nozzle from nozzle holder on blast hose. Ensure
blast hose is placed in a container suitable for catching the media. Ensure Operator is
prepared for strong recoil, the blast hose will provide strong recoil as the media exits the
blast hose. Activate Remote Control System per Operator’s Manual. When Blast Pot is
empty, only air will exit the blast hose. Deactivate the Remote Control System to
depressurize the Blast Pot. Place Metering Valve (3) in the CLOSED position.
• Inspect Blast Pot components for damage. Replace damaged components before use.
• Cover Blast Pot when not in use to reduce debris and water intrusion.
Troubleshooting
If the Blast Pot does not function properly, check the following:
SYMPTOM (Cause) ACTION
Blast Pot will not pressurize
(Damaged components, improper air supply,
Remote Control System malfunctions)
Blast Pot will not depressurize or
depressurizes slowly
(Damaged components)
No air and/or media exits the blast nozzle
(Blockages, Metering Valve)
Intermittent media flow
(Wet media, Metering Valve,
Blast Nozzle)

Refer to Remote Control System Operator’s Manual.
Insufficient air supply. Ensure minimum of 50 psi
is supplied to Blast Pot and sufficient air volume to
support blast nozzle.
Ensure internal piping is aligned with Fill Hole.
Ensure Pop Up Valve and Pop Up Valve Seat are
seating without air leaks. Replace damaged
components.
Refer to Remote Control System Operator’s Manual.
Refer to Muffler Operator’s Manual.
Depressurize Blast Pot. Inspect nozzle and blast
hose for blockage. Remove blockage or remove
components from use.
Pressurize Blast Pot and open and close Choke Valve
rapidly. If problem persists refer to Metering Valve
Operator’s Manual.
Damp or wet media. Remove media from Blast Pot
by cleaning out the vessel. Ensure dry media is
used.
Install a Moisture Separator at the inlet of the Blast
Pot. Increase the inner diameter of Air Supply hose.
Blast Nozzle is worn or too large for compressor size.
Replace Blast Nozzle.
Always depressurize the entire
blasting system, disconnect all
electrical power sources and
lockout/tagout all components
before any maintenance or
troubleshooting is attempted.
Failure to comply with the above
warning could cause electrical
shock and inadvertent activation
of equipment resulting in death
or serious injury.
Crushing and pinching are
normal functions of this
component. Do not place body
parts or foreign objects in any
area where there are moving
parts. Failure to comply with the
above warning could result in
death or serious injury.
High decibel noise levels are
generated during the blasting
process which may cause loss
of hearing. Ensure appropriate
Personal Protective Equipment
and hearing protection is in use.
Failure to comply with the above
caution may result in minor or
moderate injury.
Release of high speed media
and compressed air occurs
during depressurization of the
Blast Pot. Ensure appropriate
Personal Protective Equipment
is in use. Failure to comply with
the above caution may result in
minor or moderate injury.
To reduce media intrusion in the
air supply hose, depressurize
the Blast Pot before shutting off
air supply from compressor.
