WARNING

Overview
8311075R
Overview
The Reactor E-10 is a portable, electric-pow-
ered, 1:1 mix ratio proportioner, for use with a
wide variety of coatings, foams, sealants, and
adhesives. Materials must be self-leveling and
pourable, and may be applied with impinge-
ment mix spray guns, disposable mixer guns,
or flush-type mix manifolds.
Reactor E-10 is gravity-fed from 7 gal. (26.5
liter) supply tanks mounted on the unit. The
tanks are translucent to allow monitoring of
fluid level.
Severe duty, positive displacement reciprocat-
ing piston pumps meter fluid flow to the gun for
mixing and applying. When set to recirculation
mode, Reactor E-10 will circulate fluids back to
the supply tanks.
Heated models include separate thermostati-
cally controlled heaters for each fluid, and an
insulated hose bundle with circulation return
hoses. This allows the hoses and gun to be
preheated to the desired temperature before
spraying. Digital displays show the tempera-
tures of the two fluids.
An electronic processor controls the motor,
monitors fluid pressures, and alerts the opera-
tor if errors occur. See STATUS Indicator,
page 13, for further information.
Reactor E-10 has two recirculation speeds,
slow and fast, and an adjustable pressure out-
put.
Slow Recirculation
• Slow circulation results in a higher temper-
ature transfer in the heater, so hoses and
gun heat up quicker.
• Good for touchup or low flow spraying, up
to moderate temperature.
• Not used to circulate full tanks up to tem-
perature.
• Use with 245 fa blowing agent foams, to
minimize heat returned to tank and reduce
frothing.
Fast Recirculation
• Use to support higher flow rates or higher
temperatures by preheating the tanks.
• Agitates fluid within tanks, to avoid heating
only the fluid at the top of the tank.
• Use for flushing.
Pressure Adjust
Automatically maintains selected pressure out-
put for dispensing or spraying.

Isocyanate Hazard
311075R 9
Isocyanate Hazard
Foam Self-ignition
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 perfor-
mance and the life of all wetted parts.
To prevent exposing ISO to moisture:
• Always use a sealed container with a desic-
cant dryer in the vent, or a nitrogen atmo-
sphere. Never store ISO in an open
container.
• Keep the felt washers in the pump wet-cups
saturated with Graco ISO pump oil, Part
No. 217374. 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 (see page 63).
• Never use reclaimed solvents, which may
contain moisture. Always keep solvent con-
tainers closed when not in use.
• Never use solvent on one side if it has been
contaminated from the other side.
• Always park pumps when you shutdown,
see page 27.
• Always lubricate threaded parts with Part
No. 217374 ISO pump oil or grease when
reassembling.
Spraying 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 provid-
ing sufficient ventilation in the work area. If
sufficient ventilation is not available, a sup-
plied-air respirator is required for everyone in
the work area.
To prevent contact with isocyanates, appro-
priate personal protective equipment, includ-
ing 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 manufac-
turer’s warnings and material MSDS.
The amount of film formation and rate of
crystallization varies depending on the
blend of ISO, the humidity, and the tem-
perature.

Keep Components A and B Separate
10 311075R
Keep Components A
and B Separate
Changing Materials
• When changing materials, flush the equip-
ment multiple times to ensure it is thor-
oughly clean.
• Always clean the fluid inlet strainers after
flushing, see page 28.
• Check with your material manufacturer for
chemical compatibility.
• Most materials use ISO on the A side, but
some use ISO on the B side.
• Epoxies often have amines on the B (hard-
ener) side. Polyureas often have amines on
the B (resin) side.
NOTICE
To prevent cross-contamination of the equip-
ment’s wetted parts, never interchange com-
ponent A (isocyanate) and component B
(resin) parts.

Setup
311075R 15
Setup
Connect Reactor E-10 to the correct power
source for your model. See TABLE 2. Models
with two power cords must be connected to
two separate, dedicated circuits. See FIG. 5.
Some models include cord adapters (55, 56)
for use outside North America. Connect the
appropriate adapter to the unit’s power cord
before connecting to your power source.
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by
providing an escape wire for the electrical cur-
rent due to static build up or in the event of a
short circuit.
1. Locate Reactor E-10
a. Locate Reactor E-10 on a level
surface.
b. Do not expose Reactor E-10 to
rain.
2. Electrical requirements
Improper wiring may cause electric shock or
other serious injury if work is not performed
properly. Have a qualified electrician perform
any electrical work. Be sure your installation
complies with all National, State and Local
safety and fire codes.
3. Ground system
a. Reactor E-10: grounded through
power cord.
b. Generator (if used): follow your
local code. Start and stop gener-
ator with power cord(s) discon-
nected.
c. Spray gun: grounded through the
supplied fluid hoses, connected
to a properly grounded Reactor
E-10. Do not operate without at
least one grounded fluid hose.
d. Object being sprayed: follow your
local code.
e. Solvent pails used when flushing:
follow your local code. Use only
metal pails, which are conduc-
tive, placed on a grounded sur-
face. Do not place pail on a
nonconductive surface, such as
paper, plastic, or cardboard,
which interrupts grounding conti-
nuity.
f. To maintain grounding continuity
when flushing or relieving pres-
sure, hold a metal part of spray
gun firmly to the side of a
grounded metal pail, then trigger
gun.

8. Fill wet-cups
Keep the felt washers in the pump
wet-cups saturated with Graco ISO
pump oil, Part No. 217374. The lubricant
creates a barrier between the ISO and
the atmosphere.
Fill wet-cups through slots
in plate, or loosen screws
and swing plate aside.
TI6985a
Pump rod and connecting rod move during
operation. Moving parts can cause serious
injury such as pinching or amputation. Keep
hands and fingers away from wet-cup during
operation. Shut off Motor Power
before filling wet-cup.
9. Fill fluid tanks
NOTICE
To prevent cross-contamination of fluids and
equipment parts, never interchange compo-
nent A (isocyanate) and component B (resin)
parts or containers.
Have at least two 5 gal. (19 liter) pails to
transfer fluid from drums to supply tanks.
Label one pail “A” and the other “B”, using
the red and blue labels provided. Always
doublecheck which material you have before
pouring it in the supply tanks. Pouring is eas-
ier if pails are not filled to the top.
Open only one supply tank at a time, to avoid
splashing material from one tank into the
other when filling.
Using a drill and mixing blade, mix filled or
separated materials in the pail before add-
ing to the tanks. Material left in the tanks
overnight may need to be remixed in the
tanks.
