Pressure Relief Procedure
1. Turn the ES ON/OFF valve OFF.
2. Turn off the air bleed valves to the fluid source and
to the gun.
3. Trigger the gun into a grounded metal waste con-
tainer to relieve the fluid pressure.
4. Open the pump drain valve, having a waste con-
tainer ready to catch the drainage. Leave the pump
drain valve open until you are ready to spray again.
5. If the nozzle or hose is completely clogged or pres-
sure is not fully relieved, slowly loosen the hose end
coupling. Now clear the nozzle or hose.
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.
