Pressure Relief Procedure
This procedure describes how to relieve pressure from
the orbital dispenser. See your supply unit or system
documentation for instructions on relieving pressure for
the entire system. Use this procedure whenever you
shut off the orbital dispenser and before checking or
adjusting any part of the system, to reduce the risk of
serious injury.
1. Shut off the material supply. Follow the Pressure
Relief Procedure in the material supply instruction
manual.
2. Make sure that all material valves are open.
3. Make sure the pump air supply has been turned
OFF.
4. Shut off the conditioning unit to the automatic dis-
pense valve. See the conditioning unit's documenta-
tion for more information.
5. Actuate the PrecisionSwirl dispense valve repeat-
edly until no fluid flows. Have a container ready to
catch the drainage from the orbital dispenser.
6. Relieve air pressure to the dispense valve.
7. If the orbital dispenser nozzle or dispense valve fluid
hose is completely clogged or if pressure has not
been fully relieved after following the steps above,
very slowly loosen the 3/4 in.-16 swivel union
between the dispense valve and the orbital dis-
penser, and relieve pressure gradually, then loosen
completely. Now clear the nozzle or hose.
MATERIAL FLUID HAZARD
To reduce risk of injury, wear eye protection, gloves,
and protective clothing when installing, operating, or
servicing this orbital dispenser.
SKIN INJECTION HAZARD
The system pressure must be manually relieved to
prevent the system from starting or spraying acciden-
tally. 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:
•
Are instructed to relieve the pressure
•
Stop spraying/dispensing
•
Install or clean the nozzle
•
Check or service any of the system equipment
PRESSURIZED FLUID HAZARD
High pressures can cause serious personal injury. Be
sure to open the orbital dispenser during system
start-up to alleviate pressure which might occur in the
system due to material expansion.
