Fluid Voltage Discharge and	Pressure Relief Procedure
Grounding Procedure

WARNING

Electric Shock Hazard

The fluid supply is charged with high volt- age until the voltage is discharged. Contact

with the charged components of the isola- tion system or spray gun electrode will

cause an electric shock. To avoid an electric shock, follow the Fluid Voltage Discharge and 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 safety enclosure for the isolated fluid supply.

1.Turn the ES ON/OFF valve OFF and wait 30 sec- onds.

2.Remove 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 sup- ply pail. If you see any arcs, see Electrical Trouble- shooting on page 39.

WARNING

Pressurized Equipment Hazard

The system pressure must be manually

relieved to prevent the system from starting or spraying accidentally. To reduce the risk of an injury from electric shock, accidental spray from

the gun, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:

•are instructed to relieve the pressure

•stop spraying

•check or service any of the system equipment

•or install or clean the fluid nozzle.

1.Turn the ES ON/OFF valve OFF.
