WORKING
Optimal coating results
– When relative humidity of 55–65% optimal coating results are expected.
– For the required electrostatic effect the work pieces to be coated must be conductive
and grounded.
– In the case of a wood coating, optimum results are achieved with a minimum of 12%
residual moisture.
Prerequisites
Ensure that:
The regular safety checks are carried out in accordance with Chapter
,
Commissioning is carried out in accordance with Chapter
.

VM 5020WA control unit
1. Set the main switch (1) to position 1.
During the start-up phase, the device automatically performs an internal function
test and then automatically switches to recipe 1 (15).
2. Set the desired recipe.
See Chapter
and the following for information on how to operate the control unit.
Product supply
3. Open the compressed air supply.
4. Set pump pressure regulator (9) depending upon the paint viscosity (see operating
manual of the product pressure generator).
– DD10 pump: approx. 0.2–0.6 MPa; 2–6 bar; 30–90 psi
– DD10-/ZIP52 pump with product pressure regulator: approx. 0.3–0.6 MPa; 3–6 bar;
40–90 psi
5. DD10-/ZIP52 pump with product pressure regulator:
Set product pressure regulator (10) to approx. 0.05–0.2 MPa; 0.5–2 bar; 7–30 psi
operating pressure.
6. Set external atomizing air to approx. 0.2 - 0.4 MPa; 2 - 4 bar; 30 - 60 psi.
