System Pressure Relief
System pressure must be relieved before you can safely proceed with many
troubleshooting and service‐related activities. Follow this procedure
whenever you need to relieve system pressure.
WARNING! Risk of burns. Failure to relieve system pressure can cause hot
material to spray from a connecting point. Relieve system pressure before
loosening or removing a hose, module, or any other part of a hot melt system.
Wear heat‐protective clothing, safety goggles (ANSI Z87.1 or equivalent),
and safety gloves.
1. Shut off the main air supply or set the air pressure regulator to zero (0).
2. Momentarily activate the purge switch on the controller.
3. When the service activity is completed, restore the system to normal
operation.
