Important Two-Component Material Information
Important Two-Component Material Information
Isocyanate Conditions
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 vis-
cosity. If used, this partially cured ISO will reduce perfor-
mance and the life of all wetted parts.
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.
NOTE: The amount of film formation and rate of crystal-
lization varies depending on the blend of ISO, the
humidity, and the temperature.
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 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.
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.
•
•
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.
Material Self-ignition
•
•
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.
Some materials may become self-igniting if applied
too thickly. Read material manufacturer’s warnings
and material MSDS.
Changing Materials
•
When changing materials, flush the equipment mul-
tiple times to ensure it is thoroughly clean.
Keep Components A and B
Separate
•
•
Always clean the fluid inlet strainers after flushing.
Check with your material manufacturer for chemical
compatibility.
•
Most materials use ISO on the A side, but some use
ISO on the B side.
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 (isocyanate) and component B (resin)
parts.

Installation
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray
gun/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.
Grounding
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by pro-
viding an escape wire for the electrical current due to
static build up or in the event of a short circuit.
Mount the Pump
Mount the pump directly to the wall (order Wall Mounting
attached and tightened securely to the air motor. Con-
nect the other end of the ground wire (S) to a true earth
ground.
Wall-Mounted Pumps
1. Be sure the wall can support the weight of the
pump, bracket, hoses and accessories, as well as
the stress caused during operation.
2. Position the wall bracket about 1.2-1.5 m (4-5 ft)
above the floor. For ease of operation and service,
make sure the pump air inlet, fluid inlet, and fluid
outlet ports are easily accessible.
S
3. Using the wall bracket as a template, drill 10 mm
(0.4 in.) mounting holes in the wall. Wall mounting
dimensions are shown on page 31.
GS
FIG. 4. Ground the Pump.
ti12914a
4. Attach the bracket to the wall. Use 9 mm (3/8 in.)
screws that are long enough to keep the pump from
vibrating during operation.
Air and fluid hoses: Static electricity may build up
when fluids flow through pumps, hoses, and sprayers. At
least one hose must be electrically conductive, with a
maximum of 500 ft. (150 m) combined hose length to
ensure grounding continuity. Check electrical resistance
of hose. If total resistance to ground exceeds 25 meg-
ohms, replace hose immediately.
NOTE: Be sure the pump is level.
Cart-Mounted Pumps
Kit 24E885 is available if you plan to bolt your cart to the
floor. It includes two spacers that keep the legs stable.
Bolts not included.
Air compressor: follow manufacturer’s recommenda-
tions.
Spray gun / Dispense valve: Ground the spray gun
through connection to a Graco-approved grounded fluid
hose.
Air and Fluid Hoses
Be sure all air hoses (N) and fluid hoses (M) are prop-
erly sized and pressure rated for your system. See FIG.
3. Use only electrically conductive fluid hoses.
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 sur-
face, such as paper or cardboard, which interrupts
grounding continuity.

Operation
9. In a direct supply system, with the pump and lines
primed, and with adequate air pressure and volume
supplied, the pump will start and stop as the
gun/valve is opened and closed.
Prime and Adjust the Pump
NOTICE
The maximum fluid inlet pressure is 15 psi (0.1 MPa,
1.0 bar). Damage to the bellows may occur if you
exceed this pressure. Do not use another pump or
checking device to supply the bellows pump.
10. In a circulating system, the pump runs continuously
and speeds up or slows down as the system
demands until the air supply is shut off.
11. Use the air regulator to control the pump speed and
the fluid pressure. Always use the lowest air pres-
sure necessary to get the desired results. Higher
pressures cause premature tip/nozzle and pump
wear.
1. Lock gun trigger. Remove tip guard and spray tip
from gun. Refer to gun manual.
2. Close gun air regulator (D) and pump air regulator
(H) by turning knobs counterclockwise reducing
pressure to zero. Close bleed-type air valve (E).
Also verify that all drain valves are closed.
NOTICE
Never allow the pump to run dry of the fluid being
pumped. A dry pump quickly accelerates to a high
speed, possibly damaging itself. If your pump accel-
erates quickly, or is running too fast, stop it immedi-
ately and check the fluid supply. If the supply
container is empty and air has been pumped into
the lines, refill the container and prime the pump
and the lines with fluid, or flush and leave it filled
with a compatible solvent. Be sure to eliminate all
air from the fluid system.
3. Check that all fittings throughout system are tight-
ened securely.
4. Position pail close to pump. Do not stretch suction
hose tight; let it hang to assist fluid flow into pump.

5. Hold metal part of gun (L) firmly to side of grounded
metal pail, unlock trigger, and hold trigger open.
To avoid the buildup of static charge, do not rub the
plastic bottle with a dry cloth while it is attached to
the pump. Remove the bottle to clean, if needed.
6. Open bleed-type air valve (E). Slowly open the
pump air regulator (H) until the pump starts.
7. Cycle pump slowly until all air is pushed out and the

determine how often maintenance is required. Establish
a preventive maintenance schedule by recording when
and what kind of maintenance is needed, and then
determine a regular schedule for checking your system.
5. Hold a metal part of the gun firmly to a grounded
metal pail.
6. Trigger gun. Flush system until clear solvent flows
from gun.
8. Clean the tip guard, spray tip, and fluid filter element
separately, then reinstall them.
Tighten Threaded Connections
Before each use, check all hoses for wear or damage.
Replace as necessary. Check that all threaded connec-
tions are tight and leak-free.
9. Clean inside and outside of suction tube.
Flushing
Flush the pump:
•
•
•
•
Before first use
When changing colors or fluids
Before repairing equipment
Before fluid dries or settles out in a dormant pump
(check the pot life of catalyzed fluids)
•
•
At the end of the day
Before storing the pump.
Flush at the lowest pressure possible. Flush with a fluid
that is compatible with the fluid you are pumping and
with the wetted parts in your system. Check with your
fluid manufacturer or supplier for recommended flushing
fluids and flushing frequency.
