Installation of the anti-vibration fittings

1. The rubber elements as well as the fitting locks are engraved on the inside.
   

• When positioned towards "L" there is 1mm gap between the housing and the fan frame, resulting in the maximum possible decoupling.
• When you position the rubber elements towards "S" they fit flush with the housing.

2. The fan is then mounted into place using the washers and push-pins.
   

Do not touch the fan during operation!
