Prepare to Service Automatic
Dispense Valve
If the unit is hot, determine whether or not you can
service the unit after it has cooled down. Some
materials, like polyurethanes, may cure permanently
when cooled and exposed to air, preventing you from
disassembling the dispense valve. If you are working
with such a material, service the unit while the material
is at a temperature where the material is soft enough to
work with. If the material can be reheated at a later time,
you can service the unit after it has cooled, reheating
the material as necessary.
Perform this procedure before servicing the automatic
dispense valve.
1. Relieve the system pressure.
2. Make sure material flow has been shut off.
3. Make sure system air has been shut off.
4. Remove power from the automatic dispense valve.
5. If the material in the dispense valve can be
reheated, wait for the dispense valve to cool thor-
oughly before servicing it.
If the material in the dispense valve cures perma-
nently when cooled and/or exposed to air, service
the unit while the material is at a temperature where
the material is soft enough to work with.
WARNING
To reduce the risk of serious injury, whenever you are
instructed to relieve pressure, always follow the
WARNING
HOT SURFACE AND FLUID HAZARD
The material and equipment will be hot!
To
reduce the risk of injury, wear eye protection,
gloves and protective clothing when
servicing this dispensing system component.
