9.19 Bolt Type Shut Off Nozzle Maintenance
WARNING
This procedure is done in the hot condition. Wear appropriate personal
protective equipment such as heat resistant gloves and goggles or a face
shield. Failure to do so can result in serious injury.
Failure to lower the shutoff heater temperature setpoint to ambient
temperature before removing the heater band will result in heater damage
and may result in injury.
Compressed air will cause the molten plastic to splash. Wear appropriate
protective clothing.
CAUTION
If the E-Multi injection unit is installed in the horizontal orientation, the well
surrounding the shut off nozzle bolt will accumulate plastic material. The
material must be regularly cleaned out or the bolt may not function properly
or it may seize. In a vertical orientation, any excess plastic material will
drain out and regular cleaning is not needed.
CAUTION
1.
Open the shut off valve using the controller software.
a) Navigate to the Valve Gate screen by tapping the valve gate button.
b)
Navigate to the Shut Off Nozzle screen by tapping the shut off nozzle
button.
c)
Open the shut off nozzle by tapping the Always Open button. For this
button to be enabled the three indicator lights must be on.
2. If possible, remove the heater band from the nozzle to allow better access
to the shut off bolt.
