Hazardous Location Approval
Models using a G3000, G3000HR, G3000A, or intrinsically safe Coriolis meter for both A and B meters are
approved for installation in a Hazardous Location - Class I, Div I, Group D, T3 or Zone I Group IIA T3.
Maximum Working Pressure
Maximum working pressure rating is dependent on the fluid component options selected. The pressure rating is
based on the rating of the lowest rated fluid component. Refer to the component pressure ratings below.
Example: Model AD110Y has a maximum working pressure of 190 psi (1.31 MPa, 13.1 bar).
Check the identification label on the EasyKey or fluid station for the system maximum working pressure.

WARNING

Important Two-Component Material Information
12 312778G
Important Two-Component Material Information
Isocyanates (ISO) are catalysts used in two component
materials.
Isocyanate Conditions
Material Self-ignition
Keep Components A and B
Separate
Spraying or dispensing materials that contain
isocyanates creates potentially harmful mists,
vapors, and atomized particulates.
• Read and understand the fluid manufacturer’s
warnings and Safety Data Sheet (SDS) to know
specific hazards and precautions related to
isocyanates.
• Use of isocyanates involves potentially hazardous
procedures. Do not spray with this equipment
unless you are trained, qualified, and have read
and understood the information in this manual and
in the fluid manufacturer’s application instructions
and SDS.
• Use of incorrectly maintained or mis-adjusted
equipment may result in improperly cured
material. Equipment must be carefully maintained
and adjusted according to instructions in the
manual.
• To prevent inhalation of isocyanate mists, vapors,
and atomized particulates, everyone in the work
area must wear appropriate respiratory protection.
Always wear a properly fitting respirator, which
may include a supplied-airrespirator. Ventilatethe
work area according to instructions in the fluid
manufacturer’s SDS.
• Avoid all skin contact with isocyanates. Everyone
in the work area must wear chemically
impermeable gloves, protective clothing and foot
coverings as recommended by the fluid
manufacturer and local regulatory authority.
Follow all fluid manufacturer recommendations,
including those regarding handling of
contaminated clothing. After spraying, wash
hands and face before eating or drinking.
Some materials may become self-igniting if applied
too thick. Read material manufacturer’s warnings and
Safety Data Sheet (SDS).
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.

Important Two-Component Material Information
312778G 13
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.
NOTE: The amount of film formation and rate of crystal-
lization varies depending on the blend of ISO, the
humidity, and the temperature.
Changing Materials
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.
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.
• Check with 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 have aminies on the A (resin) side.

Important Acid Catalyst Information
14 312778G
Important Acid Catalyst Information
The 2KS Plural Component Proportioner is designed for acid catalysts (“acid”) currently used in two-component,
wood-finishing materials. Current acids in use (with pH levels as low as 1) are more corrosive than earlier acids.
More corrosion-resistant wetted materials of construction are required, and must be used without substitution, to
withstand the increased corrosive properties of these acids.
Acid Catalyst Conditions
Moisture Sensitivity of Acid
Catalysts
Acid catalysts can be sensitive to atmospheric moisture
and other contaminants. It is recommended the catalyst
pump and valve seal areas exposed to atmosphere are
flooded with ISO oil, TSL, or other compatible material
to prevent acid build-up and premature seal damage
and failure.
Acid is flammable, and spraying or dispensing acid creates potentially harmful mists, vapors, and atomized
particulates. To help prevent fire and explosion and serious injury:
• Read and understand the fluid manufacturer’s warnings and Safety Data Sheet (SDS) to know specific
hazards and precautions related to the acid.
• Use only genuine, manufacturer’s recommended acid-compatible parts in the catalyst system (hoses,
fittings, etc). A reaction may occur between any substituted parts and the acid.
• To prevent inhalation of acid mists, vapors, and atomized particulates, everyone in the work area must
wear appropriate respiratory protection. Always wear a properly fitting respirator, which may include a
supplied-air respirator. Ventilate the work area according to instructions in the acid manufacturer’s SDS.
• Avoid all skin contact with acid. Everyone in the work area must wear chemically impermeable gloves,
protective clothing, foot coverings, aprons, and face shields as recommended by the acid manufacturer
and local regulatory authority. Follow all fluid manufacturer recommendations, including those regarding
handling of contaminated clothing. Wash hands and face before eating or drinking.
• Regularly inspect equipment for potential leaks and remove spills promptly and completely to avoid direct
contact or inhalation of the acid and its vapors.
• Keep acid away from heat, sparks, and open flames. Do not smoke in the work area. Eliminate all ignition
sources.
• Store acid in the original container in a cool, dry, and well-ventilated area away from direct sunlight and
away from other chemicals in accordance with acid manufacturer’s recommendations. To avoid corrosion
of containers, do not store acid in substitute containers. Reseal the original container to prevent vapors
from contaminating the storage space and surrounding facility.
NOTICE
Acid build-up will damage the valve seals and reduce
the performance and life of the catalyst pump. To pre-
vent exposing acid to moisture:
• Always use a sealed container with a desiccant
dryer in the vent, or a nitrogen atmosphere.
Never store acids in an open container.
• Keep the catalyst pump and the valve seals filled
with the appropriate lubricant. The lubricant
creates a barrier between the acid and the
atmosphere.
• Use only moisture-proof hoses compatible with
acids.
• Always lubricate threaded parts with an
appropriate lubricant when reassembling.
