Pressure Relief Procedure

Flushing

Flush equipment only in a well-ventilated area. Do not spray flammable fluids. Do not turn on heaters while flushing with flammable solvents.

•Flush out old fluid with new fluid, or flush out old fluid with a compatible solvent, such as toluene, naptha, or mineral spirits before introducing new fluid.

•Use lowest possible pressure when flushing.

•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.

Only use flush solvents that are compatible with Fluo- roelastomer seals. Non-compatible solvents will dam- age seals and cause hazardous conditions, such as high pressure leaks and pressure switch failure.
