7.4.1 Cleaning procedure A
7.4.1.1 Pre-cleaning with non-flammable detergent
- Clean the entire atomizer including the 60° intermediate flange with
non-flammable detergent and a cloth or brush.
Most of the dirt can be removed thus.
The atomizer cannot be cleaned residue-free with just non-flammable
detergents.
Barely visible residues of paint and detergents form a protective film.
This coat leads to leakage currents when the high voltage current is
switched on.
7.4.1.2 Main cleaning with n-propanol or iso-propanol
- Heavy contamination: Before the main cleaning of the atomizer,
pre-clean the atomizer with a wet cloth with non-flammable
detergent.
- Light contamination: Carry out main cleaning without
precleaning.
- Moisten a clean cloth with volatile cleaning agent (n-propanol or
iso-propanol).
- Wring cleaning cloth well before cleaning.
- Remove the leftover dirt coat from the atomizer with the damp
cloth.
7.4.1.3 Drying the atomizer
Dry the whole atomizer with a dry clean cloth.
7.4.2 Cleaning procedure B
7.4.2.1 Cleaning with non-flammable detergent
As an alternative to cleaning procedure A, you can also clean the
atomizer exclusively with non-flammable detergent.
- Clean the surface of the atomizer including the 60° intermediate
flange very scrupulously with non-flammable detergent.
Only residues that can be removed completely while drying may
remain.
7.4.2.2 Drying the atomizer
Dry whole atomizer with a clean, dry, anti-static cloth. Make sure you
remove all residues completely.
