To prevent equipment damage, do not
circulate fluid containing a blowing agent
without consulting with your material supplier
regarding fluid temperature limits.
NOTE:
NOTE:
NOTE: Optimum heat transfer is achieved at
lower fluid flow rates with temperature set
points at desired drum temperature.
To circulate through gun
manifold and preheat hose, see
Circulation Through Gun Manifold, page 38
.
1. Route the circulation lines back to respective
component A or B supply drum. See
Typical Installation with system fluid
manifold to drum circulation, page 16
.
Use hoses rated at the maximum
working pressure of this equipment. See
Technical Specifications, page 59
2. Follow
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.
3. Set the pressure relief/spray valves (SA, SB)
to pressure relief/circulation

on the ADM screen.
5. Use jog mode to circulate fluid until the
desired drum temperature for ISO and RES
temperatures reach their respective targets.
Reactor systems allow the entire system to
be in jog mode, or A and B-side transfer
pumps to be put into jog mode separately.
