turn them off and allow to cool before flushing. Do
not turn on heaters until fluid lines are clear of sol-
vent.
• Cover fluid container and 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.
