turn on heaters until fluid lines are clear of sol-
vent.
• Use the lowest possible pressure when flushing to
avoid splashing.
• Before color change or shutdown for storage, flush
at a higher flow rate and for a longer time.

Guidelines
Flush new systems if coating materials will be contami-
nated by 10W oil.
Flush system when any of the following situations occur.
Flushing will help prevent materials from clogging the
line between hoppers and pump inlets.
