ELECTROSTATIC DISCHARGE
Static discharge may ignite flammables.
Electrostatic discharge can be hazardous to the operator and the equipment. The static charge of
CO2varies with the amount of dry ice and humidity present.
GROUND THE MATERIAL BEING CLEANED
Always ground the material being cleaned to assure safe operation while blasting.
1. Know your environment.
• Electrostatic buildup changes as humidity levels change and will vary by location.
Electrostatic discharge is higher at low humidity levels and occurs most often during
winter.
2. Attach static bond cable.
• To minimize electrostatic buildup between the part being cleaned and the
applicator, attach the static bond cable between the target surface and the blast hose
connection or to an electrically conductive supporting structure. Use a conductivity
tester for confirmation.
3. Plug into a grounded power outlet.
• This step is critical for electrostatic dissipation. If the ground is not connected, a
charge may build up on the unit or the applicator.
CO2SAFETY
• The SDI Select 60 uses solid state carbon dioxide (CO2). CO2is nontoxic, non-corrosive and
nonconductive. It is approved by the FDA and USDA.
• Solid CO2is extremely cold (-109 °F/-78 °C). Always protect skin from direct contact with
CO2pellets, nuggets or slices. Direct contact with skin or eyes quickly causes tissue damage.
• Vapor CO2can displace the oxygen from any breathing environment rapidly. Only operate
the SDI Select 60 with a proper ventilation system that maintains the concentration levels of
the governing codes of your local/national body.
• Always review and observe all safety guidelines when using materials that displace oxygen.
• All operators and supervisors should familiarize themselves with the literature on the
physiological characteristics of CO2before using the SDI Select 60. The information can be
obtained from the governing codes of your local/national body.
• Always use a CO2monitoring device when using the SDI Select 60 in a confined space.

UNIT OPERATION
START UP
Read all safety instructions before operation and follow them closely (p. 1-2)
Always wear proper personal protective equipment including eye protection to guard against flying
objects, ear protection to prevent hearing loss and gloves to protect hands from exposure to
cryogenic temperatures and sharp blade surfaces.
If an air drop is seldom used or is being used with the SDI Select 60 for the first time, water and rust
may have collected in the line. Before connecting to the air supply, purge the line to prevent
contamination of the SDI Select 60.
Before loading dry ice, clean excess moisture from the trough area with compressed air nozzle.
Before starting the SDI Select 60, verify the following parameters:
• The air supply pipe is at least 1" (25 mm) in diameter.
• The air pressure does not exceed the blast hose and blast system pressure ratings.
• The incoming air temperature does not exceed 122 ºF (50 ºC).
• The power switch, bleed valve and applicator safety switch are in the OFF (O) position.
• The dry ice trough is dry, clean and free of debris (use compressed air nozzle if it is not).
To start the SDI Select 60:
1. Securely attach the blast hose and control cable to the SDI Select 60.
2. Securely attach the blast applicator to the blast hose and control cable.
3. Securely attach a nozzle to the blast applicator.
4. Securely attach the air supply hose to the SDI Select 60 and fully extend hose whip check.
5. Securely attach the static bonding cable to the target surface and to an electrically

• The SDI Select 60 must be purged to ensure it is free of moisture to avoid forming a
clog between the feeder and shaver.
16. Set the dry ice feed rate and blast pressure to the desired setting.
17. Move the applicator blast switch to the “Off” position.
18. Verify the pusher plate is pushed back to the end of the trough away from shaver wheel.
19. Place dry ice into the trough. The SDI Select 60 is designed to use any type of dry ice,
including feeding full 3mm pellets (see p. 13).
•If using ice blocks/slices, load through the dry ice
block loading door, placing dry ice against the
rotary knives.
•For best performance, position smaller blocks/slices as shown in the following image when
stacking them in the trough.
•If using pellets/nuggets, load through the dry ice pellet/nugget
loading lid. Fill to the top of the blade wheel.
•Do not overfill the SDI Select 60 (fill only to the top
of pusher plate).
When using pellets/nuggets in extreme humidity, set pusher plate to the middle of the trough. In
order to achieve this, first ensure you have an empty trough. Next, pull the trigger to move the
pusher plate to the shaver disc, open the lid and manually slide the pusher plate to the middle of the
trough.

20. Close the dry ice loading block door or the dry ice pellet/nugget loading lid.
21. Move the applicator blast mode switch to the “Air and Ice” position.
22. Squeeze the blast applicator trigger to blast.
ADJUST THE AGITATION CONTROL
The SDI Select 60's design helps keep dry ice from forming a clog in the trough and between the
feeder and the shaver by isolating the trough, adding thumper agitation and using bursts of air in
the feeder chamber to break up any dry ice clumps that may begin to form during operation.
The bursts of air are controlled by the agitation control switch located on the Control Panel. The
switch can be set to automatic, manual or off.
The agitation control switch's center position is OFF (O). Cold Jet recommends using this setting
unless clogging is a frequent problem.
The agitation control switch's left position is AUTOMATIC. In the automatic setting, thumper
agitation will actuate and there will be a short blast of air in the feeder chamber every time the
blast applicator trigger is pulled and every 5-7 seconds afterwards. This setting is useful in high
humidity environments where the dry ice particles want to cling together.
The agitation control switch's right position is MANUAL (I). The SDI Select 60 will blast air into the
feeder chamber and the thumper agitation will actuate as long as the switch is held in this position.
The manual setting can be used as necessary to ensure the trough and feeder chamber remain free
and clear of any buildup that may form during use. Cold Jet recommends using the manual setting
occasionally during normal use.
ADJUST THE BLAST PRESSURE
The blast pressure regulation is an optional feature that allows you to adjust the blast pressure of
the SDI Select 60. By turning the blast pressure control knob, an operator can go from maximum
available operating pressure to a controlled blast pressure.
To adjust the blast pressure:
1. Turn the regulator bypass switch clockwise to activate blast pressure regulation.
2. To increase air pressure, rotate the blast pressure control knob clockwise until the desired
pressure is displayed on the regulated air pressure gauge. To decrease air pressure, rotate
the blast pressure control knob counter-clockwise until the desired pressure is displayed on
the regulated air pressure gauge.
• If the blast pressure control knob will not rotate, unlock the knob by pulling it
outward.
3. With the blast applicator on, pull the blast applicator trigger for a brief moment to verify
blast pressure setting.
