Isocyanate Conditions
Spraying or dispensing materials containing isocyanates creates potentially harmful mists, vapors, and
atomized particulates.
Read material manufacturer’s warnings and material
MSDS to know specific hazards and precautions
related to isocyanates.
Prevent inhalation of isocyanate mists, vapors, and
atomized particulates by providing sufficient ventilation in the work area. If sufficient ventilation is not
available, a supplied-air respirator is required for
everyone in the work area.
To prevent contact with isocyanates, appropriate personal protective equipment, including chemically
impermeable gloves, boots, aprons, and goggles, is
also required for everyone in the work area.
Isocyanate Conditions
• Keep the ISO lube pump reservoir (if installed) filled
with Graco Throat Seal Liquid (TSL), Part 206995.
The lubricant creates a barrier between the ISO and
the atmosphere.
• Use moisture-proof hoses specifically designed for
ISO, such as those supplied with your system.
• Never use reclaimed solvents, which may contain
moisture. Always keep solvent containers closed
when not in use.
• Always lubricate threaded parts with ISO pump oil
or grease when reassembling.
Changing Materials
• When changing mater ials, flush the equipment multiple times to ensure it is thoroughly clean.
• Always clean the fluid inlet strainers after flushing.
• Check with your material manufacturer for chemical
compatibility.
Material Self-ignition
Some materials may become self-igniting if applied
too thickly. Read material manufacturer’s warnings
and material MSDS.
Moisture Sensitivity of Isocyanates
ISO will react with moisture (such as humidity) to form
small, hard, abrasive crystals, which become suspended in the fluid. Eventually a film will form on the surface and the ISO will begin to gel, increasing in viscosity.
If used, this partially cured ISO will reduce performance
and the life of all wetted parts.
NOTE: The amount of film formation and rate of crystallization varies depending on the blend of ISO, the
humidity, and the temperature.
To prevent exposing ISO to moisture:
• Always use a sealed container with a desiccant
dryer in the vent, or a nitrogen atmosphere. Never
store ISO in an open container.

Grounding
Grounding
This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric
shock by providing an escape wire for the electric current.
Metering valve: attach ground wire from grounding lug
to true earth ground. See Component Identification
starting on page 8.
Fluid hoses: use only electrically conductive hoses.
Feed system components: attach ground wire from
grounding lug to true earth ground. See feed system
manual for grounding points.
Fluid supply container: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts
grounding continuity.
Overview
This single-component meter and dispense device
accurately meters liquid and semi-paste materials.
The machine is ideal for a single-component application
requiring very small and precise shots.
The ratio of the pneumatic cylinder area to pump shaft
area provides the adjustable pressure intensification
needed to move the liquids through the needle with a
flow rate suitable for production requirements.
The complete system is enclosed. See Sequence of
Operation on page 16.

(1). Tighten the screws in a cross pattern gradually
to prevent binding due to misalignment (like you
would tighten lug nuts on a car tire).
20. Install the short air lines on the left and right sides of
the valve.
Install the Needle Block Assembly
21. Install any removable needles that were previously
removed.
22. If your valve has cycle detection, slide the cycle
detection sensors into the slots on the end caps and
secure with the set screws. Do not overtighten the
set screws as the sensors may be damaged.
Mount the Valve End Caps to the Seal Plate Cups
11. Install a lubricated U-cup Seal (4) onto the left Spool
Shift Piston (21) with lip side out as shown. Lubricate the bore in the End Cap (19). Slide the piston
into the left End Cap (19) tucking the lip of the seal
into the End Cap carefully.
12. Install the Piston/End Cap onto the left Seal Plate
Cup (26) using four Screws (18). Tighten the screws
in a cross pattern gradually to prevent binding due
to misalignment (like you would tighten lug nuts on a
car tire).
13. Push the Spool into the left side until it contacts the
piston.
14. Repeat steps 13 and 14 for the right side.
Install the Drive Cylinder
15. Install lubricated O-ring (5) on top of the Divorced
Section (10).
23. Connect the air lines.
24. Perform the Dry Run, Loading & Priming and Output
Verification procedures. Perform Operation Adjustment procedures if required.
