component A or B supply drum. Use hoses rated at
the maximum working pressure of this equipment,
see hose manual.
3. Set RECIRC/SPRAY valves (SA, SB) to RECIRC.
4. Turn Main Disconnect Switch (R) ON.
5. Open air inlet ball valve.
6. Set temperature targets; see page 22. Turn on
heater.
7. Set both Air Regulator pressures to start at 15 psi
(1.0 bar).
8. Turn PARK/RUN switch to RUN.
9. Turn Pump Mode Function switch to START.

Read Warnings; see page 4. Do not circulate fluid
containing a blowing agent without consulting with
your material supplier regarding fluid temperature
limits.
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 relive pressure when machine is
operating.
