✓Checklist
System grounded
Verify all grounding connections were made. See
Grounding, page 21.
All connections tight and correct
Verify all electrical, fluid, air, and system connec-
tions are tight and installed according to the man-
ual instructions.
Fluid supply containers filled
Check all supply containers - A1 (A2 and A3, if
present), B, and solvent.
Dose valves set
Check that the dose valves are set correctly. Start
with the settings recommended in Valve Set-
tings, page 38, then adjust as needed.
Fluid supply valves open and pressure set
Component A and B fluid supply pressures should
be equal unless one component is more viscous
and requires a higher pressure setting.
Solenoid pressure set
75-100 psi inlet air supply (0.5-0.7 MPa, 5.2-7
