Fluid Circulation
Fluid Circulation
Circulation Through Reactor
Do not circulate fluid containing a blowing agent without consulting with your material supplier regarding fluid temperature limits.
To circulate through gun manifold and preheat hose, see page 31.
1. Follow Initial Startup, page 21.
Do not install shutoffs downstream of the PRESSURE RELIEF/SPRAY valve outlets (BA, BB). The valves function as overpressure relief valves
when set to SPRAY 
. Lines must be open so valves can automatically relieve pressure when machine is operating.
2.See Typical Installation, with Circulation, page 10. Route circulation lines back to respective com- ponent A or B supply drum. Use hoses rated at the maximum working pressure of this equipment. See Technical Data, page 37.
3.Set PRESSURE RELIEF/SPRAY valves (SA, SB) to
PRESSURE RELIEF/CIRCULATION

5. Set temperature targets, see page 22. Turn on
A and B heat zones by pressing | . |
Do not turn on 
heat zone unless hoses are already loaded with fluid.
6. Press 
to display actual temperatures.
7. Turn the air regulator to a low pressure until A
and B temperatures reach targets. Increase the pressure once the temperatures are on target.
