ECO-series suction blast cabinets 19
4.1.6 Foot pedal
Position the foot pedal on the Áoor at the front of the cabinet for easy accessibility.
Blast cabinet is designed for one-person operation. Be sure you can quickly remove your
foot from the pedal in an emergency.
4.2. Blasting operation
4.2.1 Media loading
With the exhauster off, add clean dry media, by pouring it into the cabinet hopper
through the cabinet loading door. Do not Àll past the cone on the reclaimer.
OverÀlling will result in media carryover to the dust collector and possibly blockage
in the conveying hose. ReÀll only after all media has been recovered from the cabinet. The
minimum amount of media to charge the system is as follows:
ECO-80S, ECO-100S, ECO-120S ECO-140S - 20kg
ECO-80SF, ECO-100SF, ECO-120SF, ECO-140SF - 20kg
ECO-80SL, ECO-100SL, ECO-120SL, ECO-140SL - 20kg
4.2.2 Media unloading
To empty the cabinet of old media turn off the exhauster. There are two different ways
of unloading media. The metering valve is mounted on a cover over a Áange underneath
the hopper. Place an empty container underneath the metering valve before removing the
1” screw on the bottom of the valve. The blast media should Áow out. If media doesn’t Áow,
it has caked. Open the cabinet door and stir media until it starts to Áow. If the blast media
is severely caked, one can also remove the Áange cover to which the metering valve is
afÀxed. Loosen the screws securing the cover to the Áange, and remove. Media will Áow into
container.
4.2.3. Parts loading and unloading
Parts may be loaded and unloaded through the front cabinet door. The door may be
opened so far as to allow loading from above, allowing use of a travelling crane, thereby
increasing operator safety. Blasted parts must be free of oil, water, grease, or other
contaminants that will clog media or Àlters. By closing the door, be certain that the door is
sealed securely or door interlock system will prevent blasting.
