CAUTION Use only Cold Jet approved dry ice for blast media. The use of any
other media will lead to loss of warranty coverage
h. Close the DX cover if equipped.
i. Close the trough lid.
Blasting Dry Ice Particles
For optimum performance while blast cleaning:
y Position the MicroClean 2 and blast hose to prevent kinking and allow for maximum
maneuverability.
y Hold the nozzle perpendicular to surface being cleaned at a distance of 2-6 inches
(5-15 cm).
y To nd the optimum feed rate, start at 0 and gradually increase until the desired cleaning
result and/or cleaning performance is achieved.
y Use a lower feed rate when the air pressure in is below 50 psi (3.4 bar).
Follow the instructions below to start blasting dry ice particles:
1. On the precision applicator, press the air/ice control (II) to activate (green light ON).
2. It is recommended to start blasting next to the target (but in a safe place) and move onto the
target.
3. Move the nozzle back and forth keeping it perpendicular to the surface being cleaned.
4. Monitor the trough level and reload dry ice blocks or pellets as needed:
a. On the applicator, the status light will be solid red when the trough is full and start
ashing when the trough level is low to empty.
b. On the control panel, the trough level is indicated by the color of the led bar. Green is
full, yellow is half-full, and red is empty.
5. Adjust settings or select a recipe:
a. To adjust the settings:
i. Use the rotary encoder dial to adjust the feed rate and blast pressure.
