CLEANING THE UNIT
A clean state is the best method of ensuring operation with-
out problems. After you have finished work, clean the unit.
Under no circumstances may coating material rests dry and
harden in the unit. The cleaning agent used for cleaning (only
with a flash point above 21 °C) must be suitable for the coat-
ing material used.
Warm water improves the cleaning effect in
the case of water-dilutable coating materials.
For spray work:
Secure the spray gun, refer to the operating
manual of the spray gun. Remove and clean
the tip.
1. Open the discharge tap.
2. Set ON/OFF switch to ON.
3. Turn the pressure control valve back in order to set a mini-
mal pressure.
Only for units with suction system:
Remove suction sys-
tem from material container, leave return hose in material
container until hardly any material escapes. Immerse the
suction system in a suitable cleaning agent.
4. Close the discharge tap.
5. Hold the gun or material ball valve/hose whip in an open
bucket. Pull the trigger on the gun or open the material
ball valve to pump out the remaining material (if appro-
priate, increase the pressure at the pressure control valve
slowly in order to obtain a higher material flow).
The container must be earthed in case of
coating materials which contain solvents.
Caution! Do not pump in a container with
small opening (bunghole)!
See safety regulations.
6. Release the trigger on the gun or close the material ball
cock.
7. Fill up hopper with suitable cleaning agent.
8. Open the discharge tap .
9. Pre-clean the hopper and filter with a brush.
10. Pump suitable cleaning agent in the circuit for several
minutes.
11. Close the discharge tap
12. Hold the gun or material ball cock/whip hose in an open
bucket. Pull the trigger on the gun or open the material
ball cock to pump the cleaning agent out of the hopper.
Do this by pulling and releasing the trigger on the gun
several times/opening and closing the material ball cock.

outside of the hose.
Wipe down unit externally with a cloth which has been im-
mersed in a suitable cleaning agent.
