Prime Empty Sprayer

Prime A and B Fluids

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

NOTE: The equipment is tested with mineral oil at the factory. If necessary, flush out the oil with a compatible solvent before spraying. See Empty and Flush Entire System (new sprayer or end of job), page 27.

Do not install the gun spray tip yet. To avoid splash- ing, use the lowest pressure possible to prime.

1.Condition the materials prior to adding to the hop- pers (J). Ensure that the resin materials are thor- oughly mixed, homogenous, and pourable prior to adding to the hopper. Stir the hardeners back into suspension prior to adding material to hopper.

2.Fill the A and B reservoirs with proper materials. Fill the A side (blue) with major volume of material; fill the B side (green) with minor volume of material (unless 1:1 mix ratio).

J

3. Move the recirculation lines (U) to empty containers.

6.Slowly open the air regulator (CB).

7.Dispense fluid in to the containers until clean fluid comes out of the A and B recirculation lines.

8.Decrease air pressure. Close the main air shutoff valve (CA).

9.Move the recirculation lines (U) back to the correct hopper (J).

10.If using heaters, heat fluid throughout system before spraying. See Recirculate or Re-Prime After a Pump Runs Dry, page 23.
