Flushing
• Flush out old fluid with new fluid, or flush out old
fluid with a compatible moisture-free solvent.
• Use lowest possible pressure when flushing.
• To flush feed hoses, pumps, and the heater sepa-
rately from the heated hoses, set PRESSURE
RELIEF/SPRAY valves (SA, SB) to PRESSURE
RELIEF/CIRCULATION. Flush through bleed lines
(N).
• To flush entire system, circulate through gun fluid
manifold (with manifold removed from gun).
• Always leave hydraulic oil or a non-water based,
non-water absorbent fluid in system. Do not use
water.
Flush equipment only in a well-ventilated area. Do
not spray flammable fluids. Do not turn on heaters
while flushing with flammable solvents.
Only use flush solvents that are compatible with
Fluoroelastomer seals. Non-compatible solvents will
damage seals and cause hazardous conditions, such
as high pressure leaks.
