10.6 Flushing Setup
1. In order to adjust the Flushing Setup, the password must be known. Press SETUP on the Pendant, and enter the
password. For help with the pendant, refer to
8.1 Pendant Guide
.
2. Advance to the System screen, and adjust the settings as needed, using the table below as a guide.
The recommended settings are a baseline for 25 foot x 1/4” ID fluid hose. Adjust the values accordingly.
NAME
SUGGESTED INITIAL
SETTING
DESCRIPTION
First Flush
AIR
Air or Solvent to initially flush fluid lines.
First Flush Time
15 seconds
Duration of first flush. This flush is used to move paint out of the
system before attempting to “clean” with the chop process.
Air Chop Time
1 second
Duration of each air burst in the chop process
Solvent Chop Time
1 second
Duration of solvent burst in the chop process
Chop Duration
30 seconds
Total duration of chop process.
Last Flush
SOLVENT
Last flush with Air or Solvent. Final clearing of system—this is also
the fluid left in the system if shut down.
Last Flush Time
20 seconds
Duration of last flush - should be timed to minimize solvent waste
but still completely load the fluid lines with solvent.
Load Volume
300cc—Use the chart from
9.2 Power Up Procedure
Volume needed to load mixed material into the fluid lines.
The following factors will influence
the choices listed above:
Worst case flushing
—Always set up the flush parameters using the most viscous/worst
case resin material.
Flushing air and solvent pressure
—Higher pressures may reduce the time needed
to flush the system, but can create significant spitting from the spray gun during the
process.
Material viscosity
—Viscous materials may move more slowly and require additional
time to be purged from the system.
Hose volume/ length
—Longer fluid lines encompass a larger volume and may require
a longer flush time. Also pressure drop through a longer hose or smaller diameter hose
will affect the time required to purge paint and clean the system.
Spray gun tip size
—Small tips may restrict flow during a flush.
Try to optimize the system to minimize solvent usage
during color changes and flushes by:
n
Using air instead of solvent for the first flush
n
Let the “chop” process do most of the cleaning
n
Don’t use more solvent than necessary for the last solvent flush.
