Pressure Relief Relief Procedure Procedure
Pressure Pressure Relief Procedure
This equipment stays pressurized until pressure
is manually relieved. To help prevent serious
injury from pressurized fluid, such as splashing,
follow the Pressure Relief Procedure when you
stop spraying and before cleaning, checking, or
servicing the equipment.
1. Turn OFF (O) the ES On/Off switch.
2. Follow the Fluid Voltage Discharge and
Grounding Procedure, page
3. Turn off the air bleed valves to the fluid source
and to the gun.
4. Trigger the gun into a grounded metal waste
container to relieve the fluid pressure.
5. Relieve fluid pressure in the fluid supply unit as
instructed in your fluid supply unit manual.

Fluid Fluid Voltage Discharge
Grounding Procedure Procedure
Grounding Grounding Procedure
The fluid supply is charged with high voltage until
the voltage is discharged. Contact with the charged
components of the voltage isolation system or
spray gun electrode will cause an electric shock.
To avoid an electric shock, follow the Fluid
Discharge Discharge Discharge and and Grounding and Grounding Grounding Procedure:
• whenever you are instructed to discharge the
voltage
• before cleaning, flushing, or servicing the system
equipment
• before approaching the front of the gun
• or before opening the isolation enclosure for the
isolated fluid supply.
1. Turn the ES ON/OFF valve OFF and wait 30
seconds.
2. Fully unscrew the door T-handle locking screw.
This will shut off the air to the gun and trigger the
grounding cylinder to discharge any remaining
electrical charge.
3. Use the grounding rod to touch the pump
and supply pail. If you see any arcs, see
