WARNING
SKIN 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 surgi-
cal treatment.
Do not stop or deflect fluid leaks with your hand, body, glove, or rag.
Follow the Pressure Relief Procedure on page 6 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 5.
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. See manual
cover for pressure rating.
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
Mounting the Flow Meter
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 explosion proof 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.
Installing the Flow Meter
Flow volume can only be measured at the location
where the flow meter is installed.
CAUTION
The bare meter weighs 33 lb (15 kg). Do not mount
the meter in the fluid line without proper support, to
prevent stress on the fluid inlet and outlet connections. See Fig. 1.
TI0850A
Fig. 1
No special fittings or brackets are required for mounting. External vibration will not affect the accuracy of
the meter.
The meter is safe for Class I; Division 1; Group D
hazardous indoor (NEMA 1) locations when
installed in accordance to NEC power requirements.
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.
To prevent turbulence and cavitation in the fluid line, be
sure the line is adequately sized and contains a minimal number of restrictions (such as valves or bends).
For mounting dimensions, refer to page 10.
Continued on page 5.

Installation
Vertical Mounting
When mounting on a vertical surface, the preferred
fluid flow is upward through the meter. See Fig. 2. This
allows solids to settle out and air to rise away from the
metering tube. This also allows thorough draining of
the meter during shutdown, to prevent fluid from drying
in the meter.
Downward flow is permitted if a check valve is installed
at the meter outlet to prevent fluid from falling through
the meter.
Do not mount the meter so the fluid line runs horizontally across the vertical mounting surface.
Grounding
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 12.
Fluid Flow Fluid Flow

Horizontal Mounting
When mounting on a horizontal surface, the meter
transmitter must be either above or below the fluid line.
This ensures that solids do not collect and air does not
become trapped in the metering tube. See Fig. 3.

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.
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.
