6 Maintenance

Ensure complete electrical isolation before performing any maintenance activity and always follow

guidelines and instructions as given in the air cooler product manual AHE00042.

6.1 Fan replacement

 

 

Unscrew fixing bolts and remove old fan. Mount new fan in identical position. Cable glands must be

positioned downwards. Use an anti-corrosion compound when remounting the fixing bolts.
Restore electric connection when the new fan has been mounted.

6.2 Driptray

 

The driptray can be opened for inspection, cleaning and maintenance purposes. Always disconnect drain

line before opening the driptray. To open tray, first loosen and remove fixing bolts and then lower driptray.
Respect the maximum opening angle (90°) to avoid damage to the driptray hinges.
