Decommissioning, dismantling
Decommissioning may only be undertaken by qualified personnel (ventilation specialists, qualified electricians) and under observation of the enclosed safety instructions.
Risk of skin burns in the vicinity of the fan caused by hot air medium, hot motor or hot housing. There is a danger to life near high-temperature fans with airstream temperatures of up to 200 °C.
Before working on the fan, wait until it (motor, housing) has cooled sufficiently and the air medium has mixed with cold air and cooled to below 60 °C. The fan should then only be approached close up and then only be touched if you are certain that it has cooled down. This applies in particular to high-temperature fans.
- Risk of cuts from metal housing plates with sharp edges. Use personal protective equipment (cut-resistant gloves) for installation work.
- Use the inspection switch to switch the fan Off/Aus and fit a padlock to make sure it isn't switched on again before decommissioning the fan.
- Wait until the fan has cooled down sufficiently and the impeller is stationary before removing the weather protection hood or any other protection against accidental contact or touching the fan.
- Now dismantle the fan and dispose of the components as described in the following chapter.
