312775J 9
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. Ventilate the
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
10 312775J
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
312775J 11
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.

the text refer to numbers and letters in the illustra-
tions.
•F
IG. 2, page 12, shows the basic components of a
manual system. Contact your Graco distributor for
actual system designs.
• Be sure all accessories are adequately sized and
pressure-rated to meet system requirements.
• There must be a shutoff valve between each fluid
supply line and the ProMix system.
• A 100 mesh minimum fluid filtermust be installed on
component A and B fluid supply lines.
• To protect the EasyKey screens from paints and
solvents, clear-plastic protective shields are avail-
able in packs of 10 (Part No. 197902). Clean the
screens with a dry cloth if necessary.
Wall Mounting
1. See Dimensions and Mounting Hole Layouts,
page 34.
2. Ensure that the wall and mounting hardware are
strong enough to support the weight of the equip-
ment, fluid, hoses, and stress caused during opera-
tion.
3. Using the equipment as a template, mark the
mounting holes on the wall at a convenient height
for the operator and so equipment is easily accessi-
ble for maintenance.
4. Drill mounting holes in the wall. Install anchors as
needed.
5. Bolt equipment securely.
Air Supply
Requirements
•Compressed air supply pressure: 75-100 psi
(517-700 kPa, 5.2-7 bar).
•Air hoses: use grounded hoses that are correctly
sized for your system.
•Air regulator and bleed-type shutoff valve:
include in each air line to fluid supply equipment.
Install an additional shutoff valve upstream of all air
line accessories to isolate them for servicing.
•Air line filter: a 10 micron or better air filter is rec-
ommended to filter oil and water out of the air supply
and help avoid paint contamination and clogged
solenoids. See FIG. 2.
Trapped air can cause a pump or dispense valve to
cycle unexpectedly, which could result in serious injury
from splashing or moving parts. Use bleed-type shutoff
valves.

Air Supply
312775J 17
Air Connections
See the System Pneumatic Schematic on page 31.
1. Tighten all ProMix system air and fluid line connec-
tions as they may have loosened during shipment.
2. Install a bleed-type air shutoff valve into the control
air filter inlet on Wall Mount Fluid Station. FIG. 4.
3. Connect a clean, dry, main air supply line to the
bleed-type air shutoff valve at the main air inlet. This
air line supplies air to operate the gun, solenoids,
and dispense valves.
NOTE: See Technical Data on page 43 for additional
air supply/consumption information.
4. lnstall a bleed-type shutoff valve into the air purge
valve line.
5. See FIG. 5. Install the supplied elbow (E), check
valve (CV), and tube fitting (F) at the inlet of the air
purge valve (APV). Use the 25 ft (7.6 m), 1/4 in. (6
mm) OD purge air tubing (AT, supplied) to connect
a clean, dry air supply to the fitting (F) at the air
purge valve inlet. Install filters/dryers as needed.
FIG. 4. Wall Mount Air Supply Inlet
NOTICE
Use a separate purge air supply line for the air purge
valve (APV). Do not connect the air purge valve to the
unit’s main air supply or to the air manifold (AM, FIG.
4), to avoid contaminating the solenoids, air logic
lines, or unit’s main air supply with fluid if the air purge
valve (APV) and check valve (CV) fail.
Do not shorten the 25 ft (7.6 m), 1/4 in. (6 mm) OD
purge air tubing (AT). Check daily for any visible sol-
vent accumulation. Notify your supervisor if solvent is

Fluid Supply
18 312775J
Fluid Supply
Requirements
ProMix models are available to operate air spray or
air-assisted systems with a capacity of up to 3800
cc/min.
• Fluid supply pressure tanks, feed pumps, or circu-
lating systems can be used.
• Materials can be transferred from their original con-
tainers or from a central paint recirculating line.
• For an airless system, the user must supply a gun
trigger signal to the ProMix 2KS.
• See manual 313599 for Coriolis meter installation
and operation instructions.
• If you are using dynamic dosing, see Fluid Connec-
tions at right and also see Setup the Fluid Mani-
fold for Dynamic Dosing on page 20.
NOTE: The fluid supply must be free of pressure spikes,
which are commonly caused by pump stroke change-
over. If necessary, install pressure regulators or a surge
tank on the ProMix fluid inlets to reduce pulsation. Con-
tact your Graco distributor for additional information.
Fluid Connections
1. Connect the solvent supply lines.
a. Connect the solvent supply line to the 1/4 npt(f)
solvent purge valve inlet. See FIG. 6.
b. Multiple color system: also connect a solvent
supply line to the color change stack (Q), top
valve 4 or 5. See FIG. 7.
NOTE: Solvent supplied by a single source can cause
cross contamination and damage to the system. Install
check valves or use separated solvent sources.
2. Connect the component A supply line(s).
Single color system: connect component
supply line to the component A flow meter
inlet.
Multiple color system: connect compo-
nent A supply lines to the color change
valve stack (S) inlets. See FIG. 7. The color
number is marked on the valve air supply
line.
NOTE: Paint Recirculating System Only
• The color change valves have two fluid
ports for each individual valve. If you are
recirculating paint, plumb the valves in one
port and out the other.
• Another option is to use a tee fitting to recir-
culate.
NOTE: Verify that all unused fluid ports on the color
change valve stack are plugged before operation. An
open port will leak fluid.
3. Connect the component B line to the component B
flow meter inlet.
NOTE: The component A and B fluid meter inlets have
fluid check valves to prevent backflow from fluid supply
pressure fluctuations. Backflow can cause ratio inaccu-
racies.
4. Connect the gun fluid supply line between the fluid
manifold static mixer outlet and the gun fluid inlet.
Do not exceed the pressure rating of the lowest rated
component. See the identification label (FIG. 1 on page
5).
To reduce the risk of injury, including fluid injection,
you must install a shutoff valve between each fluid sup-
ply line and the fluid manifold assembly. Use the
valves to shut off fluid during maintenance and service.
