Supplied Components

See FIG. 1. Components vary by package ordered. See tables on pages 6 to 7. Your package may include:

•The red-handled bleed-type master air valve (U) is required in your system to relieve air trapped between it and the air motor and gun when the valve is closed. Do not block access to the valve.

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

•The pump air regulator (X) controls pump speed and outlet pressure by adjusting the air pressure to the pump.

•The air relief valve (not shown) opens automatically to prevent overpressurization of the pump.

•The gun air regulator (T) adjusts the air pressure to the air-assisted spray gun (H).

•The air-assisted or airless spray gun (H) dispenses the fluid. The gun houses the spray tip (not shown), which is available in a wide range of sizes for differ- ent spray patterns and rates of flow. Refer to gun manual for tip installation.

•The hose bundle (L) supplies fluid (and air for AA guns) to the gun, and allows recirculation of fluid when the gun is not triggered.

•The gun swivel (J) allows for freer gun movement.

•The suction hose (N) with strainer (P) allows the pump to draw fluid from a 5 gallon (19 liter) pail.

•A fluid filter (F) with a 60 mesh (250 micron) stain- less steel element filters particles from fluid as it leaves the pump.

•DataTrak (V) provides pump diagnostics and mate- rial usage information. See page 19.

•The back pressure regulator (E) controls pressure back to the gun and maintains proper circulation pressure.

•The 3-way valve (M) allows choice to circulate fluid back to the pump or return it to the supply container.

•A fluid drain valve (G) relieves fluid pressure in the hose and gun.

•The fluid heater (D) heats the fluid as it passes through, to maintain the correct spraying viscosity.

Read and understand all instructions in the supplied heater manual 309524 before operating the heater.

Heat causes fluid to expand. If the heated fluid is trapped with nowhere to expand, it can cause compo- nent rupture. Be sure to keep the heated fluid circulat- ing (turn the 3-way valve to CIRC). Do not install a fluid shutoff device between the heater and the gun.
