■Removal/Mounting of the Solenoid Valve or Pressure Switch Connector
Do not attempt to insert or pull out the connector while the power is on. Otherwise, it may cause
switch output malfunction.
Before removal or mounting of the pressure switch connector, it is necessary to remove the
silencer assembly (exhaust block assembly). Remove the silencer assembly (exhaust block
assembly) following the procedure below in order to remove or to mount the pressure switch
connector.
Exhaust from Ejector
1. The exhaust resistance should be as small as possible to obtain the full ejector performance.
There should be no shield around the exhaust port for the silencer exhaust specification. For the
port exhaust specification, the back pressure should be 5 kPa or less, as exhaust resistance is
generated with some piping bore sizes and piping lengths.
DO NOT block the exhaust port. The product will fracture or break.
2. If the sound absorbing material is clogged, it will cause a reduction in the ejector performance.
In particular, if it is used in a dusty environment, not only the filter element, but also the sound
absorbing material can be clogged. It is recommended to replace the sound absorbing material
periodically.
3. Air is exhausted from the connecting part between the silencer case and silencer cover. This
does not affect the performance of the product.
Remove the clip using flat blade
screwdriver from the bottom of the
product. Remove the silencer assembly
(exhaust block assembly) from the body.
Remove or mount the pressure switch
connector.
