Operation
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of over-pressurization,
which can cause component rupture and
serious injury, never exceed 3000 psi (21
MPa, 207 bar) fluid pressure, or 120 psi (0.84 MPa,
8.4 bar) air pressure to the valve.
Pressure Relief Procedure
WARNING
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 dispensing
D
check or service any of the system equipment
D
install or clean the nozzle
SKIN INJECTION HAZARD
1. Shut off the air to the dispense valve, if applicable.
2. Shut off the air to the supply pumps.
3. Close the bleed-type master air valve (required in
your system).
4. Hold a metal part of the valve firmly to the side of a
grounded metal pail, and trigger the dispense
valve to relieve pressure.
5. Open the fluid drain valve (required in your sys-
tem), having a grounded metal container ready to
catch the drainage.
6. Leave the fluid drain valve open until you are ready
to dispense again.
If you suspect that the dispense needle or hose is
completely 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
needle or hose.
Electric Switch Hand Held Valve
D
Be sure the air supply lines are connected correctly
to the OPEN and CLOSE valve air ports.
D
To open or close the valve and maintain the open or
closed status, a minimum of 40 psi (280 kPa, 2.8
bar) air pressure must be supplied and maintained
at the OPEN or CLOSE port.
D
The trigger only activates the electrical switch in the
handle, which turns the remote solenoid on and off.
D
Trigger the gun to turn the solenoid on. Release the
trigger to turn the solenoid off.
Machine Mount Valve
D
Be sure the air supply lines are connected correctly
to the OPEN and CLOSE valve air ports.
D
To open or close the valve and maintain the open or
closed status, a minimum of 40 psi (280 kPa, 2.8
bar) air pressure must be supplied and maintained
at the OPEN or CLOSE port.
To open the valve:
1. Apply air pressure to the OPEN air port on the
valve, and remove air pressure from the CLOSE
air port on the valve.
2. Maintain air pressure on the OPEN air port to keep
the valve open.
To close the valve:
1. Apply air pressure to the CLOSE air port on the
valve, and remove air pressure from the OPEN air
port on the valve.
2. Maintain air pressure to the CLOSE air port to
keep the valve closed.
