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.
Keep Components A (Red) and
Moisture Sensitivity of
Isocyanates
Isocyanates (ISO) are catalysts used in two component
foam and polyurea 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.
•Keep the ISO lube pump reservoir (if installed) filled
with IsoGuard Select™, part 24F516. 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.
•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.
B (Blue) 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 (Red) and component B (Blue) parts.
143A2176J
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.
•Most materials use ISO on the A (Red) side, but
some use ISO on the B (Blue) side. See the following section.
A (Red) and B (Blue) Components
IMPORTANT!
Material suppliers can vary in how they refer to plural
component materials.
A (Red) and B (Blue) Components
Be aware that when standing in front of the manifold on
proportioner:
•Component A (Red) is on the left side.
•Component B (Blue) is on the right side.
For all machines:
•The A (Red) side is intended for ISO, hardeners,
and catalysts.
•If one of the materials being used is moisture-sensitive, that material should always be in the A (Red)
side.
•The B (Blue) side is intended for polyols, resins, and
bases.
For HFRS Systems:
The high volume material is typically the ISO and is
located on the A (Red) side. Some material chemistries
may have an ISO which is the low volume material. The
ISO must always be in the A (Red) side containing the
Isolube.
NOTE: For HFRL Systems:
The high volume material will always be the B (Blue)
side.Typical Installation

Adjust Motor Control Module Selector
Switch
NOTICE
Repair
If the Motor Control Module is replaced, the selector switch must be set prior to initial startup of the
Motor Control Module or damage may occur.
The Motor Control Module uses an 8-position selector
switch (S) to set system maximum working pressure.
See FIG.9.
The system can be configured to run in two pressure
ranges:
•0-3000 psi (0-20.7 MPA, 0-207 bar): For systems
will all components rated to 3000 psi maximum
working pressure or higher.
•0-2000 psi (0-13.8 MPA, 0-138 bar): For systems
with one or more component rated less than
3000 psi maximum working pressure. For example,
if the dispense valve is rated to 2500 psi, then the
0-2000 psi range must be used.
NOTE:The Motor Control Module selector switch (S)
position #1 sets the system to 2000 psi maximum
working pressure. Selector switch position #3 sets
the system to 3000 psi maximum working pressure.
The factory setting for the Motor Control Module selector
switch is position #1 to set the machine to 2000 psi if the
machine is shipped with no hoses or hoses rated to
2000 psi maximum working pressure. If the machine is
shipped with hoses rated to 3000 psi maximum working
pressure or higher then the factory setting for the selector switch is position #3 to set the machine to 3000 psi.
•Do not install components rated to less than the
highest pressure in the selected pressure range.
For example, if the 0-2000 psi range is selected do
not install items rated less than 2000 psi. If the
0-3000 psi range is selected do not install items
rated less than 3000 psi. Doing so may lead to
overpressurization and ruptured components.
•High-pressure fluid from ruptured components will
pierce skin. This may look like just a cut, but it is a
serious injury that can result in amputation. Get
immediate surgical treatment.
To set the Motor Control Module selector switch:
1. Turn machine power off.
2. Remove the access cover (D). See FIG.9.
3. Set the selector switch (S).
4. Install access cover (D).
D
S
257396_3b9905_04b
FIG.9
The selector switch position will be properly set at the
factory for new systems. When a motor control module
is replaced, the selector switch must be set to the correct setting by the user prior to initial startup.
To change the maximum working pressure rating of the
system in the field, all outlet components including
hoses and dispense valve must be rated at or above the
new system maximum working pressure rating. For
example, if the new system rating will be 3000 psi, all
system components must be rated to at least 3000 psi
maximum working pressure.

‡ The maximum fluid working pressure for the base machine without hoses is 3000 psi (20.7 MPa, 207 bar). If
hoses rated at less than 3000 psi are installed, the system maximum fluid working pressure becomes the rating of
the hoses. If 2000 psi hoses were purchased and installed by Graco, the working pressure for the machine is
already setup for the lower 2000 psi (13.8 MPa, 138 bar) working pressure by Graco. If the machine was purchased without hoses and aftermarket hoses rated at or above 3000 psi are to be installed, see instruction manual 3A1276 for the procedure to setup the machine for higher rated hoses. The change in working pressure is
made by changing a rotary switch setting in the Motor Control Module. The minimum pressure rating for hoses is
2000 psi. Do not install hoses with a pressure rating lower than 2000 psi.
