ing regulations and directives are applica-
ble in the Federal Republic of Germany
(available from Carl Heymanns Verlag KG,
Luxemburger Straße 449, 50939 Cologne):

Switch-off in case of emergency
 Release the trigger of the jet pistol.
 Press emergency-stop button.
The dry ice dosing is topped and the air
flow from the nozzle is interrupted.
 Interrupt the compressed air supply.

Proper use

The machine is used to remove dirt using
dry ice pellets that are speeded up using an
air jet.
The machine should not be operated in ex-
plosive environments.
Use only dry ice pellets as jet medium. Us-
ing any other jet medium can cause dam-
age to the machine.

Function

The air pressure reaches the jet pistol via a
pressure regulation valve. The valve opens
when the trigger of the jet pistol is pressed
and the air flow comes out from the jet pis-
tol. Additionally, dry ice pellets are dosaged
into the air stream via the dosing device.
With the version "IB 7/40 Advanced" the
additional dosing can be switched off at the
jet pistol. The dry ice pellets hit the surface
to be cleaned and remove the dirt. Addi-
tional heat currents are formed between
the dirt and the object to be cleaned by the
-79 °C cold dry ice pellets; this results in the
dirt being loosened. At the same time, dry
ice immediately gets coverted into gaseous
carbon dioxide on contact and requires 700
times the volume of dry ice. Thus, the dirt
penetrated by the dry ice thus gets thrown
off.
During the spraying operation through the
jet, a vibrator located on the dry ice contain-
er ensures continuous sliding of the dry ice
pellets.
