Pressure Relief Procedure
WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected 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,
D
check or service any of the system equipment,
D
or install or clean the spray tip/nozzles.
1.
Lock the spray gun trigger safety.
2.
Shut off the air to the feed pumps.
3.
Turn off the electric motor switch in a hydraulic
system.
4.
Turn off the air to the proportioning pump in an
air-powered system.
5.
Close the gun manifold fluid valves.
6.
Unlock the spray gun trigger safety.
7.
Hold a metal part of the gun firmly to the side of a
grounded metal pail, then trigger the gun to relieve
pressure.
8.
Lock the trigger safety again.
9.
If possible, allow the heater to cool before opening
the drain valves. This prevents the Resin from
frothing.
10. Open both fluid filter drain valves; have a container
ready to catch the draining fluid.
11.
If you suspect that the spray tip/nozzle or hose is
completely clogged, or that pressure has not been
fully relieved after following the steps above,
very
slowly
loosen the tip/nozzle retaining nut or hose
end coupling to relieve pressure gradually, then
loosen completely. Wear protective gloves to avoid
skin injection or burns. Now clear the tip/nozzle or
hose.
12. If you are working on any part of the heater, shut
off the main electrical power to the heater.
