Important Two-Component Material Information
Important Two-Component Material Information
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 thickly. Read material manufacturer’s warnings
and material MSDS.
Moisture Sensitivity of Isocyanates
Isocyanates (ISO) are catalysts used in two component
coatings. 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.
• 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.
• Never use solvent on one side if it has been contaminated from the other side.
• Always lubricate threaded parts with ISO pump oil
or grease when reassembling.
Changing Materials
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
of the equipment’s wetted parts, never interchange
component A (resin) and component B (isocyanate)
parts.
3A0869J 7
• 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.

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.
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 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.
If using a Graco electrostatic PRO™ Gun, a shutoff
valve must be installed in the gun air line to shutoff
the atomizing and turbine air to the gun. Contact your
Graco distributor for information on air shutoff valves
for electrostatic applications.

• Multiple color system: connect supply lines to the
component A2 and A3 dose valve inlets (DVA2,
DVA3). See F
NOTE: Solvent supplied by a single source can cause
cross contamination and damage to the system. Install
check valves or use separate solvent sources.
NOTE: Paint Recirculating System Only
• If you are recirculating paint, use the standard inlet
on Dose Valve A1 (A2, A3) or Dose Valve B.
Remove the plug directly opposite it on the dose
valve for the recirculation outlet. The second port is
on the back of the valve and must be reached from
inside the control box.
IG. 6.
• Fluid supply pressure tanks, feed pumps, or circulating systems can be used.
• Materials can be transferred from their original containers or from a central paint recirculating line.
• See manual 313599 for Coriolis meter installation
and operation instructions.
NOTE: The Coriolis meter can be used only on non-IS
systems 24F080-24F083. When installed on these systems, the meter’s hazardous location intrinsically safe
status is voided.
• If you are using dynamic dosing, see Fluid Connec-
tions, this page. See also Set Up the Fluid Manifold for Dynamic Dosing, page 16.
NOTE: The fluid supply must be free of pressure spikes,
which are commonly caused by pump stroke changeover. If necessary, install pressure regulators or a surge
tank on the ProMix 2KE fluid inlets to reduce pulsation.
Contact your Graco distributor for additional information.
Fluid Connections
1. See FIG. 6. Connect the solvent supply line to the
1/4 npt(f) solvent valve inlets (SVA and SVB).
2. Connect the component A supply line(s).
• Single color system: connect component supply
line to the component A1 dose valve inlet (DVA1).
Second port
ti16338a
FIG. 5. Paint Recirculation Port
• Another option is to use a tee fitting to
recirculate.
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
dose valve inlet (DVB).
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 inaccuracies.
4. Connect the gun fluid supply line between the static
mixer (SM) outlet and the gun fluid inlet.

NOTE: For more information about Dynamic Dosing,
see page 53.
NOTE: When using dynamic dosing it is very important
to maintain a constant, well-regulated fluid supply. To
obtain proper pressure control and minimize pump pulsation, install a fluid regulator on the A and B supply
lines upstream of the meters.
If you will be operating using dynamic dosing, the fluid
manifold must be set up properly for your application.

traffic areas in conduit to prevent damage from paint,
solvent, and traffic.
The ProMix 2KE operates with 85-250 VAC, 50/60 Hz
input power, with a maximum of 2 amp current draw.
The power supply circuit must be protected with a 15
amp maximum circuit breaker.
Not included with system:
• Power supply cord compatible to your local power
configuration. Wire gauge size must be 8-14 AWG.
• The input power access port is 22.4 mm (0.88 in.) in
diameter. It accepts a bulkhead strain relief fitting or
conduit.

Grounding
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by
providing an escape wire for the electrical current
due to static build up or in the event of a short circuit.
Connect the ProMix 2KE ground wire to the ground
screw. Connect the clamp to a true earth ground. If wall
power is used to power controls, ground electrical connection according to local codes.

Screw
Feed Pumps or Pressure Pots
Connect a ground wire and clamp from a true earth
ground to the pumps or pots. See pump or pressure pot
manual.
Air and Fluid Hoses
Use grounded hoses only.
Spray Gun
• Non-Electrostatic: Ground the spray gun through
connection to a Graco-approved grounded fluid supply hose.
• Electrostatic: Ground the spray gun through con-
nection to a Graco-approved grounded air supply
hose. Connect the air hose ground wire to a true
earth ground.

Gun Flush Box
Connect a ground wire from the Gun Flush Box ground
lug to a true earth ground.
Flow Meters
Verify that the meter cables are connected as shown in
the Hazardous Location Electrical Schematic on
page 74-75. Failure to properly connect the shield may
cause incorrect signals.
NOTE: The Coriolis meter can be used only on non-IS
systems 24F080-24F083. When installed on these systems, the meter’s hazardous location intrinsically safe
status is voided.
Follow local code.
All Solvent Pails Used When Purging
Follow local code. Use only conductive metal pails/containers placed on a grounded surface. Do not place the
pail/container on a nonconductive surface, such as
paper or cardboard, which interrupts the grounding continuity.
Check Resistance
To ensure proper grounding, resistance between
components and true earth ground must be less than
1 ohm.
