Pressure Relief Procedure
WARNING
INJECTION HAZARD
Fluid under high pressure can be in-
jected through the skin and cause
serious injury. To reduce the risk of an
injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
D
are instructed to relieve the pressure,
D
stop spraying/dispensing,
D
check or service any of the system equipment,
D
or install or clean the spray tip/nozzle.
1.
Shut off the air to the pump. If your pump has a
restrictor valve, close it also.
2.
Close the bleed-type master air valve (required in
your system).
3.
Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail, and trigger the gun/valve
to relieve pressure.
4.
Open the drain valve (required in your system),
having a container ready to catch the drainage.
5.
leave the drain valve open until you area ready to
spray/dispense again.
If you suspect that the fluid nozzle or hose is com-
pletely clogged, or that pressure has not been fully
relieved after following the steps above, very slowly
loosen the hose end coupling and relieve pressure
gradually, then loosen completely. Now clear the
nozzle or hose.
