Startup
8.Check coolant color.
Use a flashlight to inspect the color of the 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 bubbles, then the coolant level may be low. If the coolant is a milky color, then that indicates A or B material has likely leaked inside a heat exchanger 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), water drain valve (CM), and the main air 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.
