Symbols Warning Symbol Caution Symbol WARNING CAUTION This symbol alerts you to the possibility of serious injury or death if you do not follow the instructions. This symbol alerts you to the possibility of damage to or destruction of equipment if you do not follow the corresponding instructions. WARNING SKIN INJECTION HAZARD Spray from the gun, hose leaks, or ruptured components can inject fluid into your body and cause an extremely serious injury, including the need for amputation.
WARNING FIRE AND EXPLOSION HAZARD Improper grounding, poor air ventilation, open flames, or sparks can cause a hazardous condition and result in fire or explosion and serious injury. D Ground all equipment in the work area. See Grounding in your separate system manual. D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvent or the fluid being sprayed. D Extinguish all the open flames or pilot lights in the spray/dispensing area.
WARNING EQUIPMENT MISUSE HAZARD INSTRUCTIONS Equipment misuse can cause the equipment to rupture, malfunction, or start unexpectedly and result in a serious injury. D This equipment is for professional use only. D Read all the instruction manuals, tags, and labels before operating the equipment. D Use the equipment only for its intended purpose. If you are uncertain about usage, call your Graco distributor. D Do not alter or modify this equipment. Use only genuine Graco parts and accessories.
Installation Air Regulator Air Supply Fluid Regulator Fluid Shutoff Valve Wall Bracket Fluid from Pump Check Valve Applicator Typical Installation (Air–Operated Fluid Regulator Shown) General Information NOTES: D Reference numbers and letters in parentheses in the text refer to the callouts in the figures and the parts drawing. D The Typical Installation shows a typical dead-end hookup. Regulators should be mounted close to the dispense point.
Operation Adjusting the Regulator Outlet Pressure WARNING To reduce the risk of serious injury, never remove the adjusting screw or diaphragm housing when the valve is under pressure. NOTE: Model 244740 is equipped with inlet and outlet pressure sensor ports. Pressure Sensor Kit 198082 can be used to monitor inlet and/or outlet pressures. This chart shows the approximate air pressure needed to regulate the air-operated regulator to a given fluid outlet pressure.
Maintenance WARNING To reduce the risk of serious injury, including fluid injection, or splashing in the eyes or on the skin, always relieve the air and fluid pressure in the system before adjusting, repairing, or removing the regulator from the system. Flushing 4. Open the fluid regulator fully. a. Spring Operated Regulators Only. Open the fluid regulator by turning the adjusting screw (6) fully clockwise. b. Air Operated Regulator Only.
