If no signal is being supplied to the solenoid valve, use the air pressure
regulator located on the F option drive cover assembly to adjust the output
pressure to the pneumatic PCV. The gauge on the drive cover displays the
air pressure provided to the pneumatic PCV.
NOTE: If a signal is being provided to the solenoid valve, the output
pressure to the pneumatic PCV corresponds to the melter supply pressure.

downtime or breaks:
1. Press the Standby key to reduce the system temperature and place the
system in standby mode.
2. Cover the applicator nozzles with petroleum jelly or submerge them in a
suitable oil.
