Startup
8. Check coolant color.
Use a flashlight to inspect the color of th
e coolant
through sight glass (SG). The mesh filter
should
be visible inside the sight glass and the
coolant
should be green. If there are a lot of air b
ubbles,
then the coolant level may be low. If the c
oolant
is a milky color, then that indicates A o
rBmaterial
has likely leaked inside a heat exchan
ger and
that the coolant needs to be drained.
• To add more coolant, see
Refill Proportioner Coolant Loop, page 70 and
Refill Engine Coolant Loop, page 72.
• To drain the coolant system, see
Drain Coolant, page 69.
9. Switch on the air compressor, air dryer, breathing
air, and other accessories.
Complete the following steps for systems with a
supplied air compressor.
a. Before startup, close the main air shutoff
valve (CK), desiccant air dryer inlet valve
(CL), and water drain valve (CM) whenever
the pressure in the air supply tank has been
relieved.
Main Air Shutoff Valve (CK)
b. Press start on the air compressor power box
(CB). Wait until the pressure gauge (CJ) on
the air supply tank reaches 30 psi.
c. Open the desiccant dryer inlet valve (CL),
waterdrainvalve(CM),andthemainair
shutoff valve (CK).
10. During initial startup, ensure all three air
regulators are turned fully counterclockwise.
11. Open the main air shutoff valve.
12. Slowly increase the air pressure regulator
settings.
13. Load fluid with feed pumps.
a. Check that all Setup steps are complete.
See Setup, page 33.
b. If an agitator is used, open the agitator’s air
inlet valve.
c. If you need to circulate fluid through the
system to preheat the drum supply, see
Circulation Through Reactor, page 59If
you need to circulate material through
the heat hose to the gun manifold, see
Circulation Through Gun Manifold, page 60.
d. Turn both PRESSURE RELIEF/SPRAY
valves (SA, SB) to SPRAY
.

e. Adjust A and B feed pump air regulators to
desired air pressure, on front of proportioner,
to start the feed pumps. Do not exceed 130
psi (0.2 MPa, 2 bar) to the A and B feed
pumps.
