Maintenance
The frequency of checks will depend on the particular application, but note that oil consumption will increase under
the following circumstances:
Running at elevated inlet pressures (either as a result of the application or a vacuum leak.)
Running with gas ballast.
Mist filter in conjunction with an oil return kit not fitted.
5.2
Servicing
The enclosure requires no regular servicing but it is suggested that the Acoustic Enclosure is inspected yearly to
ensure safe operation.
If the fan stops turning, check the electrical cable is still connected and that the fuse does not need replacing. If the
fan needs replacing a suitably trained and supervised technician must complete the task.
Ensure that the air duct is checked regularly and clean where appropriate.
Replace battery (PP9 Alkaline-Manganese dioxide cell) annually, or in case of failure (can be tested by sounding
buzzer).
Edwards spare part recommended:
There is no other servicing required.
5.3
Cleaning
The outside surface can be cleaned with a damp cloth and mild detergent. Do not allow water near the electrical
components.
