Introduction
About This Manual
This manual should be kept with the machine and be readily accessible to machine operators and
maintenance personnel.
This manual contains information on the safety, transportation, operation, and maintenance of this
machine.
The graphics used in this manual may show machine details that may be dierent than the actual
machine. Components of the machine may have been removed for illustrative purposes or the
continuing improvement of the machine’s design may cause changes that are not included in this
publication.
The owner of this machine is responsible for verifying the operator of this machine is properly
trained and understands the contents of this manual.
About The i3 MicroClean 2
The i3 MicroClean 2 combines Cold Jet’s proven block shaving capability giving best in class micro
particle blasting performance added with its IoT/Industry 4.0 technologies. This machine adds to
Cold Jet’s existing “smart” dry ice blasting portfolio with its data monitoring and diagnostic features
with Cold Jet CONNECT. It allows customer’s key insights on the machine’s ongoing operation while
also providing Cold Jet’s technical support sta the ability to view these operational parameters for
improved technical support.
The 7” (17.8 cm) LCD display screen with digital controls allows for easy adjustments to blast settings
to dial in the optimal set up for specic applications. The customizable recipe options allows for
a user to save these settings for future cleanings, while the screen lock feature and its password
protection gives complete control of the blasting operation regardless of the operator. The i3
MicroClean 2 provides a more lightweight and compact solution that can be easily transported to
and around the job site.
The i3MicroClean 2 is designed for precision applications and is most commonly used in the Plastics
and Medical Device/Pharmaceutical industries.
Environmental Impact
Dry ice is a safe, clean, and non-toxic medium approved by the EPA, USDA, and FDA. The dry ice
used in this machine is made from reclaimed CO2generated from other industrial processes.

Safety
General Safety Guidelines
This machine is designed to comply with international design standards and the European
Machinery Directives. Therefore, using the machine does not pose a risk to the operator when the
instructions in this manual are followed carefully. However, certain precautions must be followed
during its use. To understand all the necessary precautions, the machine operator must read the
entire manual before operating or performing maintenance on the machine.
Operation and maintenance should only be performed by authorized and trained personnel. Below
are some basic safety guidelines:
yFollow local governing codes to ensure a minimum standard of safety.
yWear protective gloves, eye protection, and hearing protection.
yOperate the machine in a well-ventilated work area.
yFollow the prescribed maintenance schedule (see “Maintenance” on page <?>).
yStart up and shut down the machine according to the instructions in this manual.
yDo not operate a machine that is damaged or in disrepair.
yDo not store objects on top of machine.
CO2 Safety
This machine uses dry ice (CO2 in solid form). The temperature of dry ice is -109°F (-78.9°C). Avoid
coming into direct contact with dry ice as it may cause severe tissue damage.
Study the material safety data sheet (MSDS) of dry ice (CO2) supplied with the delivery of dry ice and
follow all the recommendations and guidelines listed therein.
Operate the blaster in a well-ventilated work area. The eects of CO2are entirely independent of
the eects of oxygen deciency. Therefore, CO2concentrations at 3-5% causes headaches, fast
breathing and discomfort while higher concentrations may cause unconsciousness, suocation or
respiratory arrest. The legal exposure limit set by OSHA is a 0.5% average over an 8-hour workday
and the acute (15 minute) exposure limit set is 3.0%.
Always use a CO2 monitoring/alarm system when working with machinery that emits CO2in a
conned room/space.
Electrostatic Discharge
Dry ice blasting may create electrostatic discharges. This machine is tted with eective electrostatic
dischargers to prevent injury or damage. Also, the machine must be plugged into a properly
grounded electrical outlet.
It is recommended to avoid operating the machine near explosive or ammable material. Also,
use a plastic scooper when handling dry ice pellets on the DX model to eliminate any electrostatic
discharge.

There may be other safety labels or warning signs on the machine that contain additional
information regarding potential safety hazards not explained in this manual. Operators and
maintenance personnel should familiarize themselves with these safety labels and warning signs.
Replace any safety labels or warning signs if they become damaged, missing, or illegible.
Cautions and Warnings
Please review the following cautions and warnings before operating or performing maintenance on
the machine.
CAUTION Read the instructions before using the machine. Only qualied personnel
should operate the MicroClean 2.
WARNING Ensure adequate ventilation when operating this equipment to prevent the
build-up of carbon dioxide gas. If used indoors or other conned space, a CO2
detector should be used to monitor for excessive unsafe levels of CO2gas, and
provide a suitable warning.
WARNING Ensure that expended dry ice media emissions are not in the vicinity of air
ventilation.
WARNING High pressure blast streams can be dangerous if subject to misuse. The blast
stream must never be directed at persons, live electrical equipment or the
machine itself.
WARNING Do not use the machine within range of persons unless they wear the
personal protective equipment (PPE).
WARNING Do not direct the blast stream against yourself or others in order to clean
clothes or foot-wear.
WARNING High pressure cleaners shall not be used by children or untrained personnel.
WARNING High pressure hoses, ttings and couplings are important for the safety of the
machine. Use only hoses, ttings and couplings recommended by Cold Jet.
WARNING To ensure machine safety, use only original spare parts from Cold Jet or
approved by Cold Jet.
WARNING The applicator and applicator hose contain electrical connections. Do not
immerse in water.

6
WARNING Do not use the machine if a supply cord or important parts of the machine are
damaged, e.g. safety devices, high pressure hoses, applicator.
WARNING Inadequate extension cords can be dangerous. If an extension cord is used, it
shall be suitable for the environment in which it is used, if used outdoors the
connection has to be kept dry and o the ground. It is recommended that this
is accomplished by means of a cord reel which keeps the socket at least 2.4
inches (60 mm) above the ground.
WARNING Always unplug the power cord when leaving the machine unattended.

Control Panel and HMI Screens
This i3MicroClean 2 uses a rotary encoder dial that allows the operator to navigate, select and adjust
settings on the control panel screen. You must rst press the rotary encoder to activate navigation.
Navigate between options by turning the rotary encoder dial left or right; this will highlight the option
in blue. Once the desired option is highlighted, simply press the dial to select it; this will highlight the
option in green. With the option selected (green), turn the rotary encoder dial left or right to adjust the
setting then press again to accept.
Some options can be adjusted directly from the home screen while other options can be found on other
screens. To access these other screens using the rotary encoder dial, navigate to the settings screen
and press to select. Continue to navigate through the screens (i.e. recipe, status, applicator, advanced,
reset, settings) and adjust the settings as needed by turning and pressing the rotary encoder dial.
When not being used, the screen on the control panel will display a screen saver with feed rate, particle
size, air pressure, blast pressure and trough level. Press the rotary encoder dial to bring up the home
screen.
Figure 1: Control Panel and Rotary Encoder Dial
There are two screen states for the MicroClean 2. A blue screen (home screen) which is the system
operating and settings screen. A black screen indicates that the MicroClean 2 is in the advanced settings
or the recipe screen. Changes can be made in each screen.
