Pressure Relief Procedure
333586E 39
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
NOTE: The ADM must be in Local control mode to
depressurize the system. See the See the E-Flo iQ
Supply System Operation manual.
NOTE: For iQ Tandem Ram Supply Systems, make
sure both Ball Valves (S) on the Tandem Block are open
to ensure pressure is fully relieved.
NOTE: To relieve pressure for the entire E-Flo iQ
Dispense System, follow steps 1 through 12. To relieve
pressure for the fluid side only, leaving air on to the ram
cylinder follow steps 1 through 9.
1. Ensure the control mode is set to Local. See Con-
trol Modes in the E-Flo iQ Supply System Opera-
tion manual.
2. At the ADM (AF) Run screen, press the soft
key for Valve Depressurization. Then press the
soft key to open the iQ Dispense Valve (B) allowing
the system to depressurize.
3. The current pump pressure and current dispense
valve pressure show the progress of the
depressurization on the Run screen.
4. When all of the pressure has been relieved in the
system, press the soft key to close the iQ
Dispense Valve (B).
5. Press the soft key to exit the valve
depressurization mode.
NOTE: If using a tandem system, perform steps 6-12 on
both units.
6. If using an ambient system, turn the Disconnect
Switch (AZ) OFF. If using a heated system, turn the
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief Pro-
cedure when you stop spraying and before cleaning,
checking, or servicing the equipment.
