Operation
Pressure Relief Procedure
This procedure describes how to relieve pressure for
the supply unit. Use this procedure whenever you shut
off the dispenser/sprayer and before checking or
adjusting any part of the system, to reduce the risk of
serious injury.
WARNING
MOVING PARTS HAZARD
Follow the
Pressure Relief Procedure
below before checking or repairing the
ram or any other part of the system and
when shutting down the system. Keep
hands and fingers away from the follow-
er plate, fluid pump inlet, and lip of the
fluid container when raising or lowering
the ram to reduce the risk of pinching or
amputating hands or fingers.
During operation, also keep hands and
fingers away from limit switches to
reduce the risk of pinching or amputating
hands or fingers.
HOT SURFACE AND FLUID HAZARD
The material and equipment will be
hot!
To reduce risk of injury, wear eye
protection, gloves and protective clothing
when installing, operating, or servicing
this dispensing system.
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, moving
parts, follow the
Pressure Relief
Procedure
whenever you:
are instructed to relieve the pressure
stop spraying/dispensing
install or clean the spray tip/nozzle
check or service any of the system
equipment
PRESSURE FLUID HAZARD
High pressures can cause serious per-
sonal injury. Be sure to
open the dis-
pense valve during system heat-up
to
alleviate pressure which might occur in
the system due to material expansion.
To relieve pressure in the supply unit, perform the
following procedure:
1. Lock the gun/valve trigger safety.
2. Shut off the main air supply to the pump.
3. Close all air bleed valves.
4. Unlock the gun/valve trigger safety.
5. Hold a metal part of the gun/valve firmly to the side
of a grounded metal drum, and trigger the gun/
valve to relieve pressure.
6. Lock the gun/valve trigger safety.
7. Have a container ready to catch the drainage, then
open the drain valve or pump bleed valve.
8. Leave the drain valve open until you are ready to
spray/dispense again.
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 guard retaining nut or hose end coupling
to relieve pressure gradually, then loosen completely.
Now clear the tip/nozzle or hose.
9. If you want to relieve pressure in the ram, see the
Ram Pressure Relief Procedure
on page 39.
