Component Maintenance—On/Off Control Option
Note
There are no replaceable components on the 4320 with the monitoring option.
Components are subject to normal wear and must be inspected and replaced as necessary. The frequency of
inspection and replacement depends upon the severity of service conditions. Conditions that may affect component
life include, but are not limited to: excessive water in the air line, freezing, or dirty air.
This section describes removing and replacing the spool valve and pneumatic gasket, the pneumatic interface and
housing gasket, and the filter assembly.
Key numbers are shown in figure 35 unless otherwise indicated.
Spool Valve and Pneumatic Gasket Removal
1. Remove the four hex socket cap screws (key 18).
2. Carefully remove the spool valve (key 17). If needed, gentle prying can be used at the corners to assist in separating
the spool valve from the 4320.
3. Remove the pneumatic gasket (key 16) from the device. Care is needed as the gasket may stick to the spool valve or
the outside face of the pneumatic interface.
4. Follow the instructions below to install a new spool valve and gasket.
