* Full load amps with all devices operating at maximum capabilities. Fuse requirements at various flow rates and
mix chamber sizes may be less.
** Values are dependent on installed pump size. Values shown are for largest available pump size.
◆Flow rate is independent of frequency 50/60 Hz.
❖Flow rate increases with flow meters removed.
‡ The maximum fluid working pressure for the base machine without hoses is 3000 psi (21 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 (14 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 Adjust Motor Control Module
Selector Switch on page 27 for the procedure to setup the machine for higher rated hoses. The change in work-
ing pressure is made by changing a rotary switch setting in the Motor Control Module. The minimum pressure rat-
ing for hoses is 2000 psi. Do not install hoses with a pressure rating lower than 2000 psi.

BURN HAZARD
Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe
burns:
• Do not touch hot fluid or equipment.
SPLATTER HAZARD
Hot or toxic fluid can cause serious injury if splashed in the eyes or on skin. During blow off of platen,
splatter may occur.
• Use minimum air pressure when removing platen from drum.
WARNING
Spraying or dispensing materials containing isocya-
nates 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 ventila-
tion 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 per-
sonal protective equipment, including chemically
impermeable gloves, boots, aprons, and goggles, is
also required for everyone in the work area.
Some materials may become self-igniting if applied
too thickly. Read material manufacturer’s warnings
and material MSDS.
Cross-contamination can result in cured material in
fluid lines which could cause serious injury or dam-
age equipment. To prevent cross-contamination of
the equipment’s wetted parts, never interchange
component A (Red) and component B (Blue) parts.

A (Red) and B (Blue) Components
8313875J
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 crystal-
lization 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 pump wet cups filled with IsoGuard
Select®, part 24F516. The lubricant creates a bar-
rier 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 contam-
inated from the other side.
• Always lubricate threaded parts with ISO pump oil
or grease when reassembling.
Changing Materials
• When changing materials, flush the equipment mul-
tiple times to ensure it is thoroughly clean.
• 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 follow-
ing section.
A (Red) and B (Blue) Components
IMPORTANT!
Material suppliers can vary in how they refer to plural
component materials.
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.
• The B (Blue) side is intended for polyols, resins, and
bases.
NOTE: For machines with material volume ratios other
than 1:1, the higher volume side is typically the B (Blue)
side.
