Important Isocyanate (ISO) Information
Important Isocyanate (ISO) Information
Isocyanates (ISO) are catalysts used in two
component materials.
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
Some materials may become self-igniting if applied
too thick. Read material manufacturer’s warnings
and material MSDS.
Keep Components A and B Separate
Cross-contamination can result in cured
material in fluid lines which could cause serious
injury or damage equipment. To prevent
cross-contamination:
•Never interchange component A and component
B wetted parts.
• Never use solvent on one side if it has been
contaminated from the other side.
Moisture Sensitivity of Isocyanates
Exposure to moisture (such as humidity) will cause
ISO to partially cure; forming 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.
NOTICE
Partially cured ISO will reduce performance and
the life of all wetted parts.
• Always use a sealed container with a desiccant
dryer in the vent, or a nitrogen atmosphere.
Never store ISO in an open container.
• Keep the ISO pump wet cup or reservoir (if
installed) filled with appropriate lubricant. The
lubricant creates a barrier between the ISO and
the atmosphere.
• Use only moisture-proof hoses compatible with
ISO.
• Never use reclaimed solvents, which may
contain moisture. Always keep solvent
containers closed when not in use.
• Always lubricate threaded parts with an
appropriate lubricant when reassembling.
NOTE: The amount of film formation and rate of
crystallization varies depending on the blend of ISO,
the humidity, and the temperature.
3A2800B 9

Important Isocyanate (ISO) Information
Changing Materials
NOTICE
Changing the material types used in your
equipment requires special attention to avoid
equipment damage and downtime.
• When changing materials, flush the equipment
multiple times to ensure it is thoroughly clean.
• Always clean the fluid inlet strainers after
flushing.
•Checkwith
your material manufacturer for
chemical compatibility.
• When changing between epoxies and urethanes
or polyureas, disassemble and clean all fluid
components and change hoses. Epoxies often
have amines on the B (hardener) side. Polyureas
often haveaminesontheA(resin)side.

Troubleshooting
Error Code Troubleshooting
System errors alert you of a problem and help
prevent off-ratio spraying. There are three types:
Advisory, Deviation, and Alarm.
An Advisory records an event in the system, and will
clear itself after 60 seconds.
ADeviation records an error in the system but does
not shut down the equipment. The deviation must be
acknowledged by the user.
If an Alarm occurs, operation stops.
If any of the three types occur:
•Alarm buzzer sounds (unless in silent mode).
•Alarm popup screen shows the active alarm code.
•Status bar on the Advanced Display Module shows
theactivealarmcode.
•Alarm is saved in the date/time stamped log.
NOTE: When an error occurs be sure to determine
the code before resetting it. If you forget which code
occurred, the Errors screen displays the 200 most
recent errors, with date, time, and description.
NOTE: In some error codes listed below, a # symbol
is shown as the last digit. This symbol represents the
applicable pump number, which can vary. The unit’s
display will show the applicable pump number as the
last digit in the code.
