NOTICE 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: Optimum heat transfer is achieved at lower
NOTE: NOTE:
fluid flow rates with temperature set points at desired
drum temperature. Low temperature rise deviation
errors may result.
Circulating fluid through the gun manifold allows
rapid preheating of the hose.
1. Install gun fluid manifold (P) on accessory
circulation kit (CK). Connect high pressure
circulation lines (R) to circulation manifold.
The Fusion AP gun manifold is shown.

2. Route circulation lines back to respective
component A or B supply drum. Use
hoses rated for the maximum working
pressure of this equipment. See
Technical Specifications, page
3. Follow procedures from
4. Turn main power switch on.
5. Set temperature targets. See
Targets Screen, page
6. Before starting the motor, unlock the hydraulic
compensator knob, then rotate counter-clockwise
until it ceases to move.
7. Press motor to start motor and pumps.
Circulate fluid at lowest possible pressure until
temperatures reach targets.
8. Press to turn on the hose heat zone.
9. Turn on the A and B heat zones. Wait until the
fluid inlet valve temperature gauges (FTG) reach
the minimum chemical temperature from the
supply drums.
10. Turn off motor.
