Pressure Relief
Procedure
1. Set START/STOP switch to STOP.
2. Push in SECURE DISABLE switch.
3. Open the back pressure regulator and all fluid drain
valves in the system, having a waste container
ready to catch drainage. Leave open until you are
ready to pressurize system again.
4. Check that pressure gauges on fluid supply and
return lines read zero. If gauges do not read zero,
determine cause and carefully relieve pressure by
VERY SLOWLY loosening a fitting. Clear obstruc-
tion before pressurizing system again.
