Caution Symbol
CAUTION
This symbol alerts you to the possibility of damage to
or destruction of equipment if you do not follow the
instructions.
D Do not exceed the maximum working pressure of the lowest rated system component. Refer to the
Technical Data on page 11 for the maximum working pressure of this equipment.
D Use fluids and solvents which are compatible with the equipment wetted parts. Refer to the Tech-
nical Data section of all equipment manuals. Read the fluid and solvent manufacturer’s warnings.
D Route hoses away from traffic areas, sharp edges, moving parts, and hot surfaces. Do not expose
Graco hoses to temperatures above 180_F (82_C) or below –40_F (–40_C).
D Do not kink or over bend the hoses or use the hoses to pull equipment.
D Wear hearing protection when operating this equipment.
D Do not lift pressurized equipment.
D Comply with all applicable local, state, and national fire, electrical, and safety regulations.

WARNING
INJECTION HAZARD
Spray from the gun, leaks or ruptured components can inject fluid into your body and cause extremely
serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin can also
cause serious injury.
D Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate
surgical treatment.
D Do not stop or deflect leaks with your hand, body, glove or rag.
D Keep your hands away from the end of the drain valve when opening it.
D Lock the gun trigger safety when you stop spraying.
D Follow the Pressure Relief Procedure on page 7 if the spray tip clogs and before cleaning,
checking or servicing the equipment.
D Follow the Pressure Relief Procedure on page 7 before removing the regulator’s adjusting knob.
D Do not pressurize the system when the fluid regulator’s adjusting knob is removed.
D Tighten all fluid connections before operating the equipment.
D Check the hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
Do not repair high pressure couplings; you must replace the entire hose.
D Use only Graco approved hoses. Do not remove the spring guard that is used to help protect the
hose from rupture caused by kinks or bends near the couplings.
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin,
inhaled, or swallowed.
D Know the specific hazards of the fluid you are using.
D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,
state and national guidelines.
D Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and
solvent manufacturer.

Installation
Fluid pressure regulators are used for accurate, positive control of the fluid pressure to spray guns, dispensing valves or atomizing heads.
Regulators installed at circulating line take-offs or
pumps are used to reduce main line pressure and
maintain the desired fluid pressure to the spray gun,
dispensing valve, or atomizing head.
Before Installing the Fluid Regulator
1. Determine placement of the fluid regulator in
system.
2. Install a ball valve for inlet and outlet of the regulator.
3. Install temporary plumbing between the ball
valves.
4. Thoroughly flush the system to remove metal
chips and other contaminants and to check for
leaks.
Installing the Fluid Regulator
1. Remove the temporary plumbing and install one
regulator for each spray gun. A mounting stud,
washers, and locknut are provided for mounting
the regulator either from the bottom or side.
2. Put sealer on threaded connections, except on
swivel unions as it interferes with the swivel action.
3. Connect the fluid supply line to the 3/8 npt(f) inlet
of the fluid regulator. Connect the fluid line between the gun and the regulator’s 1/4 npt(f) outlet
of choice. MAKE SURE that the direction of fluid
flow agrees with the IN and OUT markings on the
regulator body.
4. Flush and test the entire system.
