Blasting; Blasting Technique - Cold Jet i3 MICROCLEAN Operator's Manual

BLASTING

1.
With the air hose pressurized and the unit ready,
2.
Purge the system, of any debris, by blasting with air
for 1 minute.
Before loading the dry ice block into the trough,
turn the feed rate control to its maximum and
squeeze the trigger while holding the safety switch
to the left to purge the system.
After purging, return the feed control to zero then
slowly increase the dial to the desired blast setting.

BLASTING TECHNIQUE

• Position the blast hose for maximum maneuverability before blasting.
• Do not kink the blast hose.
• Hold nozzles perpendicular to the surface for fastest cleaning
(recommended for most applications).
• Optimum stand off distance is 2 in (5 cm) for most nozzles.
• Never allow foreign objects to enter the ice trough!
• Do not abuse the blast applicator or cable.
• Reduce the feed rate to avoid clogging the nozzle at pressures below
50 psi (3.4 bar).
• To find optimum feed rate, set the feeder speed to 0 and increase the
rate to achieve desired results.
• Blast with air only for 1 minute after breaks (to melt any water ice
build-up inside the blasting unit).
Always purge the i³
MicroClean, before
inserting the dry ice
block, by blasting
with compressed air.
