WARNING
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including
splashing in the eyes or on the skin, injury from
moving parts or electric shock, always follow this
procedure when shutting off the system, when
checking or servicing any part of the spray system,
when installing, cleaning or changing fluid nozzles,
and whenever you stop spraying.
1. Turn off the high voltage power supply.
2. Turn off the air and fluid supply to the gun.
3. Trigger the gun into a grounded metal waste
container to relieve fluid pressure.
4. Open the pump drain valve, having a waste
container ready to catch the drainage.
5. Leave the pump drain valve open until you are
ready to spray again.

safely operate an electrostatic air spray
system.
Be sure all operators are trained how to prop-
