Pressure Relief Procedure

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 off all the air to the spray gun except the cylin-
der air, which triggers the gun. If an air pilot fluid
regulator is used in the system, the air pressure is
needed at the regulator air inlet.

2. Turn off the fluid supply to the gun.
3. Trigger the gun into a grounded metal waste con-
tainer to relieve the fluid pressure.
4. If an air pilot fluid regulator is used, turn off the air
pressure at the regulator air inlet.
5. Relieve fluid pressure in the fluid supply equipment
as instructed in its instruction manual.
6. Turn off the main air supply by closing the
bleed-type master air valve on the main air supply
line. Leave the valve closed until you are ready to
spray again.
