NOTICE NOTICE
To prevent equipment damage, do not
circulate fluid containing a blowing agent
without consulting with your material supplier
regarding fluid temperature limits.
NOTE: NOTE: Optimum heat transfer is achieved at NOTE:
lower fluid flow rates with temperature set
points at desired drum temperature. Low
temperature rise deviation errors may result.
To circulate through gun
manifold and preheat hose, see
Circulation Through Gun Manifold, page
1. Follow Startup, page
To avoid injection injury and splashing,
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 system fluid
manifold to drum circulation, page
Route circulation lines back to respective
component A or B supply drum. Use
hoses rated at the maximum working
pressure of this equipment. See

3. Set PRESSURE RELIEF/SPRAY valves (SA, SB)
to PRESSURE RELIEF/CIRCULATION
4. Set temperature targets. See
Targets, page 40.
5. Press to circulate fluid in jog mode until
A and B temperatures reach targets. See
Jog Mode, page 49
about jog mode.
6. Press to turn on the hose heat zone.
7. Turn on the A and B heat zones. Wait until
the fluid inlet valve temperature gauges (FV)
reach the minimum chemical temperature
from the supply drums.
8. Exit jog mode.
9. Set PRESSURE RELIEF/SPRAY valves (SA, SB)
to SPRAY .
