Proper Use; Control Elements - Kärcher IB 15/80 Bedienungsanleitung

Warning
Risk of injury on account of flying objects.
Fix light cleaning objects properly to pre-
vent them from being dragged off with the
dry ice jet.
Do not use the appliance when there are
other persons around unless they are also
wearing safety equipment.
The appliance must not be used if a con-
necting line or important parts of the appli-
ance, e.g. safety devices, spray hose,
spray gun.
Danger of crushing on account of the dos-
ing equipment. Always remove the ma-
chine plug from the socket before removing
the protective shield of the dry ice contain-
er.

Proper use

This dry ice spray device 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 pistol (operating type switch in position
"1"). If the opreating type switch at the jet
pistol is at position "2", then dry ice pellets
are also added to the air flow via the dosing
equipment. The dry ice pellets hit the sur-
face to be cleaned and remove the dirt. Ad-
ditional 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.
