3-1. Replacing the Ejector Unit
Before replacing the ejector unit, always shut-down the main compressed air.
Since both the solenoid valve and pressure sensor are a type of connector connection, carefully
connect them to avoid improper connections. After the ejector unit has been replaced, turn on and
off the manual control head vacuum blow to check that the ejector unit functions correctly.
(Note)
Carefully disassemble the unit so that oil seals on the rear of the solenoid valve
and O-ring of the pressure sensor are not lost.
