Warnings
WARNING
MOVING PARTS HAZARD
Moving parts can pinch or amputate fingers and other body parts.
•Keep clear of moving parts.
•Do not operate equipment with protective guards or covers removed.
•Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,
follow the Pressure Relief Procedure. Disconnect power or air supply.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in the operating
area of the equipment to help protect you from serious injury, including eye injury, hearing loss, inhalation of toxic fumes, and burns. This equipment includes but is not limited to:
•Protective eyewear, and hearing protection.
•Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.
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
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 Graco IsoGuard Select
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.
®
(ISG), Part 24D086.
Keep Components A and
B Separate
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
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.
NOTICE
To prevent cross-contamination of the equipment’s
wetted parts, never interchange component A (red)
and component B (blue) parts.
Foam Resins with 245 fa
Blowing Agents
Some foam blowing agents will froth at temperatures
above 90°F (33°C) when not under pressure, especially
if agitated. To reduce frothing, minimize preheating in a
circulation system.
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.
63A0235G
A and B Components
A and B 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.
•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 ratios higher than 1:1, the higher volume is
typically the B (Blue) side.
3A0235G7
Grounding
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.
Pump: follow instructions in separate feed pump manual, supplied.
HFR: see operation manual.
Spray gun: see gun manual.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray gun or
dispense valve firmly to the side of a grounded metal
pail, then trigger the gun or valve.
Flush Pumps Before
Using
Position Drums
Place component A (red) and component B (blue)
drums as desired. Air hose (C) connecting feed pumps
is 15 ft (4.57 m) long. See F
