Turn main power ON .
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 34.

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.
