Read and heed all warnings, cautions and safety pre- cautions before operation of this unit.
Be certain anyone operating this equipment or fluid system has been trained to use it safely.
WARNING HIGH PRESSURE DEVICE. Improper usage of this equipment could result in serious injury. The pos- sibility of injection into the flesh is a potential hazard. Wear approved safety glasses or face shield and other equipment as needed to prevent injury. Never al- low any part of the human body to come in front of or in contact with the material outlet, the tip, or the material outlet of the dispensing device. An injection injury can be serious. If an injection accident should occur, it is very important that you contact a qualified physician for immediate treatment.
WARNING MISAPPLICATION HAZARD. Do not use the regulator when the fluid inlet pressure is too high for the designed operating range. Excessive inlet pres- sure can cause a
WARNING COMPONENT RUPTURE. Do not operate regulator at an inlet pressure greater than specified. To avoid possible damage or personal injury do not operate this unit at pressure higher than the stated operating range as it appears on the model plate.
WARNING DISASSEMBLY HAZARD. Do not disassemble this regulator when it is under pressure. Relieve pres- sure in the pumping system before attempting service or disassembly procedures. Disconnect air lines and carefully bleed pressure off the system. Be certain the system is not maintaining pressure due to a material restriction in the hose, line, dispensing device, or the spray or extrusion tip. Failure to relieve pressure both up stream and downstream may result in an injury upon disassembly.
WARNING BONNET REMOVAL HAZARD. Do not at- tempt to remove the four bonnet retaining bolts without first relieving the tension on the main spring. Failure to relieve tension could result in an accident upon disassembly.
WARNING PREVENT FIRES. Keep solvents away from heat, sparks or open flame. Keep containers closed when not in use. When pumping, flushing or recir- culating volatile solvents, be certain the area is ad- equately ventilated.
CAUTION FLUSH SUPPLY LINE. Before installing fluid regulator blow the supply lines clear and flush to re- move contaminates.

INSTALLATION
Refer to the typical installation view which best applies. Locate the regulator as close as possible to the spray gun or dispensing device for best pressure control.
Identify the regulator INLET / OUTLET (flow direction). The regulator is marked with an arrow on the body base (refer to figure 10).
When flexible fluid lines are used, mount the regulator securely using the (2) 1/4” - 20 threaded holes in the base (see figure 10).
Flush supply line before installing regulator.
Remote models require maximum 100 p.s.i. (6.9 bar) signal pressure. Start with a signal pressure as low as pos- sible and adjust upward until proper flow is reached.
