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 Pres- sure Relief Procedure, page 22, and tighten the throat packing nuts on both pumps.

1.If heaters are used, turn them on. To adjust the

heater temperature, refer to the Viscon HP manual for instructions, and the Heat Fluid section, page 25. Circulate as necessary.

2.Close the circulation handle (AC) and the solvent flush valve (AD). Open the dual shutoff handle (AE).

3.Adjust the main air regulator (CB) to 30 psi (0.21 MPa, 2.1 bar).

4.Remove tip. Disengage the trigger lock and trigger the gun into a grounded metal pail. Use a metal pail lid with a hole to dispense through to avoid splash- ing. Dispense out of the mix hose until a well mixed coating flows from the gun.

5. Engage the trigger lock. Install the tip on the gun.

6.Adjust the main pump air regulator (CB) to the nec- essary spraying pressure and apply a coating to a test panel.

NOTE: Run system verification tests everyday. See page 31.

7.Excess pressure increases overspray and pump wear.

8.Check and record gauge readings frequently during operation. A change in gauge readings indicates a change in system performance.

NOTE:

•A pressure drop occurs during pump stroke changeover. It should be quick and synchro- nous.

•Flush the mix manifold as necessary during the day’s operation.

9.Follow Flush Mixed Material, page 28 when you are finished spraying or before potlife expires.

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