Pre-Operation Tasks

Pre-operation Checklist

Go through the Pre-Operation Checklist daily, before each use.

✔Checklist System grounded

Verify all grounding connections were made. See Grounding in the Installation manual.

All connections tight and correct

Verify all electrical, fluid, air, and system connections are tight and installed according to the Installation manual.

Fluid supply containers filled

Check component A and B and solvent supply containers.

Dose valves set

Check that dose valves are set 1–1/4 turns open. Start with the settings recommended in Valve Settings, page 18, then adjust as needed.

Fluid supply valves open and pressure set

The recommended component A and B fluid supply pressures are 1/2 to 2/3 of the target spray pressure.

NOTE: Low pressure systems may be set within a range of ± 100 psi (0.7 MPa, 7 bar); high pressure systems may be set within a range of ± 300 psi (2.1 MPa, 21 bar). If the inlet pressure is higher than the outlet pressure, ratio accuracy may be affected.

Solenoid pressure set

85-100 psi inlet air supply (0.6-0.7 MPa, 6-7 bar).
