The section of the 2K device containing the mixed material (valve unit, mixer, fluid pressure hose,
spray gun) must be flushed for longer stops (also refer to page 32) exceeding the processing time,
overnight and during the weekend.
Turn the"SPRAY" switch to OFF
Engage the gun and press the "RESET" button (21 on page 13) until spraying pressure is
reached.
Trigger the spray gun without the tip and flush, with the "FLUSH' switch in position "A", until clean
solvent is discharged from the gun. Repeat the flushing procedure with the switch in position "B".
Close the air pressure regulation valves for spraying and flushing. Close ball valve for air supply.
It is also recommended that the flushing agent is drained off and that the equipment is filled again
when work recommences (the next day), provided it has not been contaminated.
In order to drain the detergent, turn the detergent filling connector to the left (max. 180°).
Return to the original position before pouring in the solvent.
Do not tighten with a tool (lever)

Risk of breaking
When 2K devices are not used for a longer period (also refer to page 32), they must be flushed
completely (including the suction hoses for the base fluid and the hardener with solvent). To prevent
paint residue to settle, the solvent must be left in the 2K device during the period the device is not
used. We recommend the use of a "ASE" phenol alkylsulphon acid ester or MESAMOL.
Please consult the fluid supplier about the flushing agent and the compatibility of the flushing
agent.
Do not use nitro thinners or solvents as flushing agents.
