WARNING
INJECTION HAZARD
Spray from leaks, or ruptured components can inject fluid into your body and cause extremely serious
injury, including the need for amputation. Splashing fluid in the eyes or on the skin can also cause
serious injury.
Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate medi-
cal attention.
Do not stop or deflect fluid leaks with your hand, body, glove, or rag.
Follow the Pressure Relief Procedure on page 5 whenever you: are instructed to relieve pres-
sure; stop operation; or clean, check, or service the equipment.
Tighten all the fluid connections before operating the equipment.
Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.
FIRE, EXPLOSION, AND ELECTRIC SHOCK HAZARD
Improper grounding, poor air ventilation, open flames, or sparks can cause a hazardous condition and
result in fire or explosion and serious injury.
Ground the equipment as instructed in Grounding, page 4.
Never use the flow meter with an electrostatic gun isolation stand.
INSTRUCTIONS
Keep liquids away from the electronic sensor device.
Follow the material supplier recommendations when flushing or servicing the meter.
Do not service the electronic sensor. Return it to your Graco distributor for service.
If there is any static sparking while using the equipment, stop spraying immediately. Identify and
correct the problem.
EQUIPMENT MISUSE HAZARD
Equipment misuse can cause the equipment to rupture, malfunction, or start unexpectedly and result
in serious injury.
This equipment is for professional use only.
Read all instruction manuals, tags, and labels before operating the equipment.
Use the equipment only for its intended purpose. If you are uncertain about usage, call your Graco
distributor.
Do not alter or modify this equipment. Use only genuine Graco parts and accessories.
Check the equipment daily. Repair or replace worn or damaged parts immediately.
Do not exceed the maximum working pressure of the lowest rated system component. This equip-
ment has a 3000 psi (21 MPa, 210 bar) maximum working pressure.
Use fluids or solvents that are compatible with the equipment wetted parts. See the Technical
Data section of all the equipment manuals. Read the fluid and solvent manufacturer’s warnings.
Comply with all applicable local, state and national fire, electrical and other safety regulations.

WARNING
Installation
Grounding
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
To reduce the risk of fire, explosion, or
electric shock:
All electrical equipment must only be installed
by a qualified electrician.
Understand and follow your local code and
safety regulations for hazardous location wiring
of intrinsically safe circuits.
Dust and Foreign Matter
Avoid having dust or foreign matter enter the flow
meter by taking the following precautions:
Thoroughly flush the fluid supply lines before
installing the flow meter.
When installing fittings, make sure that no sealing
tape overlaps into the inside of the pipe.
Install a 200 mesh fluid filter upstream of the flow
meter.
WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
Proper electrical grounding of your
system is essential. For your safety,
read the warning section, FIRE, EXPLO-
SION, AND ELECTRIC SHOCK HAZARD, on
page 3.
1. Ground the flow meter by connecting a grounded
cable to the sensor. Part No. 116005 Cable is
available (must be ordered separately).
Have a qualified electrician check the electrical
grounding continuity between the flow meter
sensor and a true earth ground; remove the cable
connector from the sensor and measure the resistance from the cable connector Pin A to true earth
ground. Refer to the Wiring Diagram on page 7.
If the resistance is greater than 25 ohms, check
the cable ground connection. Reconnect the
ground sheath or replace the cable. Do not operate the system until the problem is corrected.
Installing the Flow Meter
Flow volume can only be measured at the location
where the flow meter is installed.
The meter is intrinsically safe for Class I; Division
1; Group D hazardous indoor (NEMA 1) locations
when installed with an intrinsically safe power
device and wiring.
Refer to ANSI standards ISA-RP12.6, NEC Article
504 and the Canadian Electrical Code Appendix F.
Do not use more than 200 ft. (61 m) of cable.
2. Always ground the fluid supply unit, using one of
the following options:
a. Mount the meter to a grounded conductive
surface, or
b. Connect the conductive fluid hose to the meter
inlet and outlet, or
c. Connect a ground wire to the meter’s 1/4–20
unc mounting holes.
3. Never use the flow meter with an electrostatic gun
isolation stand.

Operation
Pressure Relief Procedure
WARNING
INJECTION HAZARD
The system pressure must be manually relieved to
prevent the system from starting or spraying accidentally. Fluid under high pressure can be injected
through the skin and cause serious injury. To
reduce the risk of an injury from injection, splashing
fluid, or moving parts, follow the Pressure Relief
Procedure whenever you:
are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment.
1. Turn off the fluid supply to the meter.
2. Shut off all electrical power to the fluid system.
3. Follow the Pressure Relief Procedure for your fluid
system dispensing device.
Recommended Usage
Flow Volume Range
The meter flow volume range is 0.01–2.6 gal./min.
(40–10,000 cc/min.).
Checking the Meter Accuracy
1. To check the accuracy of the meter, turn your gun
fan and atomizing air off, then trigger the fluid into
a graduated cylinder; dispense at least 500 cc of
fluid.
2. Measure the volume of fluid in the beaker in cubiccentimeters (cc) and read the volume on the flow
meter monitor.
If the flow meter scale factor is not between
0.099–0.130 cc/pulse, recalibrate the flow meter.
WARNING
COMPONENT RUPTURE HAZARD
Do not exceed the maximum working pressure of
your meter or any component or accessory in your
system.
See the Technical Data for fluid and ambient
temperature limits.
Only use the flow meter with fluids that are compat-
ible with the “Wetted Parts” listed in the Technical
Data.
Maintenance
CAUTION
The only serviceable parts in the meter are the
o-rings. Order o-ring replacement kit 116004. Do not
disassemble other parts of the meter.
