B Air Filter (optional accessory, purchase separately) - Removes harmful dirt and moisture from the com-
pressed air supply.
C Gun Air Pressure Gauge - Displays atomizing air pressure to spray gun.
D Gun Air Pressure Regulator - Adjusts the air pressure to the air spray or air-assisted spray gun (L).
E Bleed Type Master Air Valve - Red-handled valve required to relieve air trapped between it and the air motor
and gun when the valve is closed. Do not block access to the valve.
F Mix Manifold - Combines A and B fluid flows out to mixer.
G Pump Air Pressure Gauge - Displays pump air pressure.
H Pump Air Pressure Regulator - Controls pump speed and outlet pressure by adjusting the air pressure to the
pump.
J Solvent Flush Inlet - On the mix manifold; provides flush point for mixed material.
K Gun Swivel - Allows for easier gun movement and comes attached to the blue hose (AA packages). The airless
gun has a built-in fluid swivel.
L Spray Gun - The air spray, air-assisted, or airless spray gun (L) dispenses the fluid. The gun houses the spray
tip or nozzle (not shown), which is available in a wide range of sizes for different spray patterns and rates of
flow. Refer to gun manual for tip installation. See Related Manuals, page 3.
M Gun Fluid Supply Hose - Blue hose. Provides the gun fluid supply.
N Gun Air Supply Hose - Transparent hose (labeled “Air Hose Only”) provides the gun air supply.
PA Fluid Pressure Gauge A Supply Side - Displays fluid pressure from pump to mix manifold
PB Fluid Pressure Gauge B Supply Side - Displays fluid pressure from pump to mix manifold
Q Pinch Guard - Shield covering all moving parts.
R Pump Fluid Outlet - Outlet port of the pump.
S Grounding Wire - Provides true earth ground for static dissipation.
T Wet-Cup - Maintains consistent lubrication for packings and keeps paint from drying on displacement rod.
U Pump Fluid Inlet - Inlet port of the pump.
VA Suction Hose with Strainer A Supply - Allows the pump to draw fluid from a 5 gallon (19 liter) pail. A fluid hop-
per with screen also is available.
VB Suction Hose with Strainer B Supply - Allows the pump to draw fluid from a 5 gallon (19 liter) pail. A fluid hop-

W Fluid Drain Valve - Relieves fluid pressure in the filter and allows for easier filter removal for cleaning.
X Mixer - Static fluid mixer. Mixes combined flows of A and B from mix manifold.
Y Motor - Powers pump
Z Pressure Relief Valve - Prevents pumps from generating pressures higher than system rated pressure. Do not
cap or restrict the bottom threaded port. Fluid must be allowed to exit the bottom port if an over pressure
occurs. Refer to Relief Valve manual. See Related Manuals, page 3.
CC Pump Outlet Hose - Provides fluid to the mix manifold from the pump.
DD Solvent Flush Supply Hose -
Provides fluid to the mix manifold from solvent pump.
EE Fluid Filter - 60 mesh (250 micron) stainless steel element filters particles from fluid as it leaves the pump.
Air Relief Valve (not shown) - Opens automatically to prevent overpressurization of the air motor.
