Pressure Relief Procedure
Pressure Relief
Procedure
Flushing
•
•
•
Flush before changing colors, before storing, and
before repairing equipment.
System pressure can cause the pump to cycle unex-
pectedly, which could result in serious injury from
splashing or moving parts.
Flush at the lowest pressure possible. Check con-
nectors for leaks and tighten as necessary.
1. Set START/STOP switch (ST) to STOP.
2. Push in SECURE DISABLE (SD) switch.
Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
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.
2. Supply the appropriate flushing material to the sys-
tem.
3. Set pump to lowest possible fluid pressure, and start
the pump.
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.
4. Flush long enough to thoroughly clean the system.

a. Pressurize the system to 250 – 275 psi.
NOTE: To calibrate the transducer in systems using the
Graco ACS Module, see the ACS manual 3A0006.
Pressure sensor information (Pr 20.34, 20.35, and
20.36) for your system must be keyed into the Vari-
able Frequency Drive before system start-up.
Do not exceed pressure rating of the system! If system
is rated to a pressure lower then 250 psi, use maxi-
mum allowable rated pressure. Refer to Operation
Manual 311593.
To prevent accidental change of pressure sensor cali-
bration parameters, they are locked by Pr 20.16. To
enter calibration parameters, perform the following
steps:
