Component Identification

Air Line

•Bleed-type master air valve (CA): Required in your system to relieve air trapped between it and the air motor when the valve is closed. Be sure the valve is easily accessible from the pump and located downstream from the air regulator.

Optional Accessories

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

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

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

•Pump air regulator (CB): Controls pump speed and outlet pressure.

•Air line filter (C): 40 micron filter removes harmful dirt and moisture from compressed air supply. Accu- mulated water is automatically drained from the fil- ter.

Fluid Line Accessories

•Fluid Manifold (AA): Controls circulation and pump priming.

•Mix Manifold (AB): Combines A and B fluid into one fluid line.

•Circulation Handle (AC): Directs fluid flow for cir- culation or mixing. Move to open position to relieve fluid pressure, prime pumps, and circulate material in hoppers. Move to closed position to spray mixed material.

•Dual Shutoff Handle (AE): Controls A and B fluid flow for mixing and dispensing. Close before flush- ing.

•Solvent Flush Valve (AD): Controls solvent flow to the mix manifold, hose, and spray gun.

•Static mixer/gun hose kit: Thoroughly mixes the two fluids and delivers the mixed fluid to the spray gun. Includes static mixer and hoses to the spray gun.

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 system or end of job), page 29.
