Spray

Wear gloves when using flush solvents and/or if fluid temperature exceeds 110° F (43° C).

NOTE:

After the first day of spraying follow Pressure Relief Procedure, page 34, and then tighten throat seals on both pumps and dosing valves.

1.If heaters are used, use heater junction box to turn them on. To adjust heater temperature, refer to the Viscon HP manual for instructions, and the Heat Fluid section, page 31.

3.Adjust pump air regulator to 30 psi (0.21 MPa, 2.1 bar).

4. Select . Press .

5.Disengage trigger lock and trigger gun into a grounded metal pail. Use a metal pail lid with a hole to dispense through to avoid splashing. Dispense flush solvent out of mix hose until a well mixed coat- ing flows from the gun.

Also, look at bar graph to ensure mix manifold restriction adjustment is within optimal range. Refer to Batch Ratio Dispense Test, page 43 and Adjust B Machine Outlet Restriction, page 33.

8.Follow Flush Mix Manifold, page 36, or Park Fluid Pump Rods, page 38, when you are finished spray- ing or before potlife expires.

NOTE:

Mixed material potlife or working time decreases with increased temperature. Pot life in hose is much shorter than dry time of coating.
