Routine Maintenance
Periodically inspect the drive for build-up of dust or obstructions that may affect ventilation of the unit. Remove this using dry air.
Preventative Maintenance
FAN CASSETTE (FRAMES D – J ONLY)

every 5 years operation, or whenever the drive trips on ‘heatsink overtemperature’ under normal operation. Spare fan cassettes are available to
order from your local Parker sales office.
