NOTE: A minimum feed pressure of 50 psi (0.35 MPa,
3.5 bar) is required at both feed inlet pressure gauges
(FP). Maximum feed pressure is 75 psi (
Maintain A (Red) and B (Blue) feed pressures within
10% of each other.

g. Turn HFR main power ON
h. Navigate to the System Setup Screen. Set the
low pressure dispense to 25%.
NOTE: The following steps are referring to the B side
(Blue) components of the system.
i. Set PRESSURE RELIEF/DISPENSE valve (SA,
SB) to DISPENSE
material side.

j. Open feed inlet valve and the material supply
ball valve on the system.
k. Navigate to the Standby Screen and push
to start pumps.
NOTE: Material will dispense into the container from

Do not install shutoffs downstream of the PRESSURE
RELIEF/DISPENSE valve outlets (BA, BB). The valves
function as overpressure relief valves when set to
DISPENSE . Lines must be open so valves can
automatically relieve pressure when machine is oper-
ating.
If circulating fluid back to the supply drums, use high
pressure hose rated to withstand the maximum work-
ing pressure of this equipment.
o. Ensure all material hose connections are tight.
p. Open the RETURN ball valves on the tank
stand.
q. Repeat steps j thru p for A side (Red).
