Specifications and Guidelines
For the operation of this system the following regulations and directives are applicable in the Federal Republic of Germany (available from Carl Heymanns Verlag KG, Luxemburger Straße 449, 50939 Cologne): – BGV D 26 Spray jet tasks – Executing instructions for BGV D 26 – BGR 117 Working in closed rooms – BGR 189 Using safety gear– BGR 195 Using of safety gloves – BGR 500 Working with spraying devices – BGI 534 Working in closed rooms – BGI 836 Gas warner
Safety Devices
Emergency-stop button
If the emergency stop button is pressed, the dry ice dosing is stopped and the airflow from the nozzle is interrupted. Switch-off in case of emergency

• Release the trigger of the jet pistol.

• Press the emergency-stop button.
  The dry ice dosing is stopped and the airflow 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 explosive environments. Use only dry ice pellets as jet medium.
Using any other jet medium can cause damage 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 airflow comes out from the jet pistol. Additionally, dry ice pellets are dosed 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. Additional 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 covered 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 container ensures continuous sliding of the dry ice pellets.
