IDENTIFICATION MARK 'X'
X: The maximum surface temperature corresponds to the permissible material temperature.
This and the permissible ambient temperature can be found in the Technical Data.
Max. surface temperature
The maximum surface temperature of the pump hangs not of the equipment (frictional
heat) separates from the opening conditions (warmed material).
Ignition temperature of coating material
Ensure that the ignition temperature of the coating material is above the maximum
surface temperature.
Ambient temperature
The permissible ambient temperature is +10 °C to +60 °C; +50 °F to +140 °F
Medium supporting atomizing
To atomize the material, use only weakly oxidizing gases, e.g. air.
Mechanical sparks can form if the unit comes into contact with metal.

Do not knock or push the unit against steel or rusty iron.
Do not drop the unit.
Use only tools that are made of a permitted material.
Surface spraying, electrostatic
Do not spray system parts with electrostatic (e.g. electrostatic spray gun).

sparks can form if there is a discharge.
Remove deposits from the surfaces to maintain conductivity.
Use only a damp cloth to clean the unit.
