In the Hot Spray process, the material is circulated as
follows:
The material is suctioned from the container into the spray
pump and is then forced through the fluid heaters where it
is warmed up. Then it flows to the high pressure filter and
further to the spray gun. If the spray gun is not operated,
the backpressure regulator opens and the material flows
back into the inlet of the spray pump.

Circulation makes it possible to maintain a constant tem-
perature - even during breaks in spraying.
Observe the pot life of the material being
sprayed. A very short pot life and long pauses
in spraying can lead to blocked circulation
return hoses.
Burn danger!
When using a fluid heater, contact with the
heated material or surfaces can lead to burns
on the hands or arms.
Wear protective gloves!

If residue solvent in the fluid heaters becomes
warm, this can lead to an explosion causing
both injury and property damage. When using
a fluid heater, observe the:
3.
Close the air tap lock (Picture 8.1.3 + 8.1.5, Pos. 1).
The setting for the atomizing air on the Air
Combi unit does not need to be changed.
Adjusting the air pressure regulator:
Unlock: Pull the control knob upwards
Lock: Push the control knob downward
Instructions for cleaning the unit
The fine atomization of solvent can create a
health hazard.
Therefore, the supply of atomizing air must be
cut off during the flushing process.
