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 PLT 60
This machine combines patented technology in a lightweight and compact design that gives the
operator unparalleled control for dry ice cleaning and other applications.
yThe Advanced Air-Flow System reduces pressure loss as the air ows straight through the
system which also decreases sublimation and loss of the dry ice particles.
yThe Blast Pressure Control System can be regulated digitally from the 7” HMI color screen on
the control panel or certain applicators.
yThe SureFlow System with Dynamic Agitation is designed to keep warm air, moisture and
debris out of the hopper while keeping the dry ice owing. The level of dry ice in the hopper
can be monitored from the HMI screen of the control panel or certain applicators.
yThe Advanced Direct Drive Feeding System is a two-stage feeding system that improves feed
rate consistency and maximizes dry ice particle integrity.
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 35).
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 hopper.
CO2 Safety
This machine uses dry ice (CO2in solid form). The temperature of dry ice is -78.9°C (-109°F). 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 with continuous CO2 -level monitoring. The eects
of CO2 are 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 discharge(s). 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 shovel when handling dry ice to eliminate any additional static electricity.

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 PLT 60.
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 pellet emissions are not in the vicinity of air
ventilation.
WARNING This machine has been designed for use with 3mm dry ice pellets
recommended by Cold Jet. The use of other cleaning agents or chemicals may
adversely aect the safety of the machine.
WARNING High pressure jets can be dangerous if subject to misuse. The jet must not 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.

6
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.
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 switch o the main disconnecting switch, or unplug the blaster power
cord when leaving the machine unattended.

Control Panel and HMI Screens
The PLT 60 uses a rotary encoder dial that allows the operator to navigate, select and adjust settings
on the control panel screen. Navigate between options by pressing the rotary encoder and 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 again 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, air
pressure, blast pressure and hopper level.
Figure 1: Control Panel and Rotary Encoder Dial
There are 2 screen states for the PLT 60. A blue screen (home screen) which is the system operating
and settings screen. A black screen indicates that the PLT 60 is in the advanced settings or the
recipe screen. Changes can be made in each screen.
