Safety equipment
Before starting wor , care should be ta en for the ind of dirt and object to be cleaned,
so that you can optionally ta e further safety measures, e.g. full protection.
For a safe operation of a dry-ice blasting unit you always need the following protecting
equipment:
1. Safety glasses
2. Ear protection
3. Long-sleeved wor ing suit
4. Protective gloves
5. Dust mas
6. Safety shoes
Caution!
In poorly ventilated areas, the elevated concentration of CO
2
can
lead to breathing difficulties and suffocation. Therefore, you should
always care for sufficient fresh air in confined spaces (exhaust and
fresh air).
When cleaning in silos, tanks or confined spaces, also ensure
adequate air circulation or use, in addition, a breathing mask, which
has an activated carbon filter interposed in the air supply line.

Emergency stop
The emergency stop button interrupts all functions of the unit immediately.
Caution!
Despite the use of the emergency stop button the unit is still under
pressure!

Safety precautions
When blasting in confined spaces sufficient supply of fresh air must be ensured, CO
2
is
odorless and tasteless. It reduces the oxygen content of the breathing air. Failure to do
so can be fatal!
If ignored, there is a risk of DEATH!
The maximum allowable concentration (maximum allowable concentration in 8 hours of
wor ) is of 5.000 ppm.
A CO
2
concentration of 8-10% (v/v) in the air is deadly!
Note:
1 kg dry-ice pellets sublimates into about 0.5m³ CO
2
when blasting.
Please avoid storing the dry-ice pellets longer than 15 minutes in the dry-
ice hopper to avoid freezing of the IC022. Hopper and dosing system may
freeze, if remaining ice stays in the hopper. Therefore, the hopper has to be
blasted empty or remaining dry-ice has to be removed by hand. Mechanical
interventions for removing the dry-ice pellets are prohibited, as they may
damage the dosing system.
When working with dry
-
ice, the safety data sheet of the supplier
must be observed. Make sure that only dry-ice pellets are filled into
the dry-ice hopper. Always use safety cloves when handling dry-ice,
because it can cause cold burns. See the safety data sheet at the end
of these operating instructions (page 21).
The dry-ice temperature is -79°C.

Due the high speed of the pellets serious injury may result. Therefore it must never be
blasted towards people or animals. Never reach into the blast- high risk of injury!
The wor space has to be closed where necessary, not to endanger third parties.
The IC 022 may only be operated by qualified personal and after a thorough training.
The user must operate the IC 022 only in flawless condition and repair any damages
immediately (see page 18).
High electrostatic charges may occur. Always ma e sure that the object to
be cleaned is grounded and remains so for the duration of the cleaning.
IC 022 is grounded continuously from the blasting gun through the blasting
hose pac age to the unit.
The user should always wear safety shoes class S2 or higher in order to protect himself
from the electrostatic charge.
eople who wear a pacemaker are not permitted to work with IC022.
Caution!
The procedure should not be used in areas with potentially
explosive air mixtures.

rocess description
The dry
-
ice blasting equipment IC 022
operates with granules of dry-ice pellets
(Ø3mm), produced through the
pressing of the CO
2
snow. The pellets
are blasted on the surface to be cleaned.
The dirt from the surface is frozen
through thermal shoc and it brea s
because of the different expansion
coefficients. The CO
2
granulate sublimes
in the moment of impact from solid to
gaseous state. Only the initial dirt
remains behind.
The dry-ice pellets in the hopper
(Ø3mm) will be mixed using a
compressed air operated dosing system,
transported through the blasting hose
and accelerated through blasting nozzle,
the pellets can reach the speed of sound
(depending on compressed air pressure
and blasting nozzle).

Operation of the blasting gun IG 022
To activate the blasting gun, pull the trigger from the handle. The blasting process will
stop by releasing the trigger, it will move in start position by itself. By closing the ice
control valve the ice supply will be interrupted, so that you can carry out the final dry of
the blasted surface only with compressed air.
With the pressure control valve you set desired blasting pressure directly on the gun.
The IC 022 has a time lag of about 2 seconds to eliminate residual ice from the dosing
system and thus avoid icing.
Caution!
Always make sure you have the gun safe and firmly in the hand in
order not to endanger yourself and others.

Start-up
For the start-up of the IC 022 proceed as follows:
1. Chec before each start-up if the pressure control valve is closed.
2. Connect the compressed air hose first with the quic coupling NW 7.2 on the rear
of the blasting unit and then with the compressed air source.
3. Chec the hose pac age and the gun for damages.
4. Open the compressed air source slowly!
5. Aim the blasting gun towards the floor and press it for about 10 seconds to
release the residual moisture from the dosing system.
6. Now fill the hopper with dry-ice pellets and close the lid to prevent foreign
bodies entering the hopper.
7. Now the IC 022 is ready for use.
Shut-down
After finishing the blasting work proceed as follows:
1. Blast the dry-ice hopper until empty.
2. Close the compressed air source.
3. Actuate the gun to release the residual compressed air.
4. Separate the compressed air hose from the unit.
5. Close the pressure control valve.

Transport
For easy transport from one place of wor to another within your company, please use
the transport handle.
For further transport of the IC 022 with a shipping company, we recommend to use the
original shipping carton included in the scope of supply.
Requirements for the compressed air
For an efficient blasting result, the compressed air to be used is of outermost importance.
The compressed air should be dry, clean, oil-free and free of foreign bodies.
We recommend that the minimum requirements for the quality of the compressed air comply
with ISO 8573-1: 12010 [1:4:1], i.e.
Particle = class 1 = 0,1 mg/m³
Water= class 4 = DTP 3°C
Oil = class 1 = 0,01 mg/m³
Non-compliance with compressed air requirements, when using the
dry-ice blasting system IC 022, the warranty is voided!
