6.1. Maintenance and Repair

Do not remove the window from the 7500-01-... control unit. If the window is damaged
or removed, the control unit cannot be repaired. A new unit is required.
Do not remove the accessory conduit hub extension, 7500-HUB-AA-01, from the
7500-01-... control unit. If the conduit hub is damaged or removed, the conduit hub
cannot be reinstalled. A new conduit hub is required. The conduit hub is an accessory
and is not included with the 7500-01-... control unit.
The only special maintenance required on the 7500 system is cleaning of the
pneumatic filters on the overall installation, when used, and periodic function
checks. This includes pressure readings within the specifications contained in this
manual. When checking pressure measurements of the 7500 control unit, use
calibrated equipment to determine the measurements, or contact a Pepperl+Fuchs
representative or the factory to send the device back for function verification.
