4 313812F
Isocyanate Conditions
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.
Material Self-ignition
• 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 materials, 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.
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.
313812F 5
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 7.
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.
Cycle Detection Spool Sensors
The spool sensors are magnetic reed switches and
must be connected to an electrical control. An LED on
the switch illuminates to indicate the shifting of the
spool.
Overview
This single-component meter and dispense device
accurately meters liquid and semi-paste materials.
The machine is designed for application that require
very small and precisely dispensed beads and/or dots of
material at a wide range of material inlet pressures.
The ratio of the flow rate/stroke length to pump shaft
area provides the adjustable pressure intensification
needed to move the separate liquids through the needle
with a flow rate suitable for production requirements.
The complete system is enclosed. See Sequence of
Operation on page 15.
