Component Identification

Air Line

Bleed-type master air valve (CA): required in your sys- tem to relieve air trapped between it and the air motor when the valve is closed.

Trapped air can cause the pump to cycle unexpect- edly, which could result in serious injury from splash- ing or moving parts.

Be sure the valve is easily accessible from the pump and located downstream from the air regulator.

Pump air regulator (CB): to control pump speed and outlet pressure.

Air line filter (C): 40 micron filter that removes harmful dirt and moisture from compressed air sup- ply. Accumulated water is automatically drained from the filter.

Fluid Line Accessories

Fluid Manifold (AA): mounts fluid gauges and over pressure relief valves. Controls circulation and pump priming.

Mix Manifold (AB): brings A and B fluid together. Provides control and check valves for A, B, and flush fluids.

Circulation Handle (AC): open to relieve fluid pres- sure, prime pumps, and circulate material in hop- pers. Close to spray mixed material.

Dual Shutoff Handle (AE): Controls A and B on/off flow into mix manifold. Press down to provide A and B fluid to the mix manifold and into the static mixer for spraying. Press up to turn off A and B before flushing the mixed material.

Solvent Flush Valve (AD): to flush solvent through mix manifold, hose, and spray gun.

Static mixer/gun hose kit: to mix the two fluids and deliver mix to the spray gun. Includes static mixer and hoses to the spray gun.

Optional Accessories

Optional Fluid Heaters (N): to heat the resin and hardener before mixing. Improves the chemical reaction and lowers viscosity to improve the spray pattern.

Optional Solvent Flush Kit (G): to flush the mix manifold. Includes a solvent pump, mounting hard- ware, and solvent supply hose.

Flush Before Using Equipment

The equipment was tested with lightweight oil, which is left in the fluid passages to protect parts. To avoid con- taminating your fluid with oil, flush the equipment with a compatible solvent before using the equipment. See

Empty and Flush Entire System (new sprayer or end of job), page 27.
