If needed, solvent may be pushed past the mix
manifold and into the mix hose, or manifolds and
hoses if multiple stages. To prevent atomizing
solvent, it may only be dispensed to a percent of the
total mix hose volume. The default value is 0%, which
will not dispense solvent beyond the mix manifold
that introduces the resin. The mix hose volume is
set by the Stage Stage # # # Hose Stage Hose Length Hose
Diameter fields. See
Diameter Diameter System Screen 5, page
The displayed volume shows the total amount of
solvent to be dispensed during the solvent push
sequence. This volume includes, at minimum, the
total fluid stream volume from the inlet color stack
to the mix manifold. Additionally, this volume will
include a percentage of the total mix hose volume,
if set to greater than 0%.

If using an electrostatic gun, to reduce the risk
of fire and explosion, confirm the mix hose
parameters are accurately represented in the
settings.
The solvent push sequence is initiated
using a soft key on the Spray Screen (see
Spray Screen, page 62) or a PLC command (see
ProMix PD3K+ Network Inputs, page
Timing is critical to avoid having the solvent push
sequence end before the last part has been finished.
The system will go into Standby and must complete a
recipe change before it can mix again.
