Pressure Relief Procedure

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.
NOTE: For iQ Tandem Supply Systems, make sure both
Ball Valves (S) on the Tandem Block (R) 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 on page 40.
2. At the ADM (AF) Run screen, press the soft
key for Valve Depressurization. Then press the
soft key to open the Dispense Valve (A) 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
Dispense Valve (A).
5. Press the soft key to exit the valve
depressurization mode.
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.
