7.7.4 Installation silencer
♦ Ensure correct installation of the silencer.
• This can cause damage to the bearings or other parts of the fan.
• The duty point may not be reachable.
• The fan may make noise.
♦ Ensure a direct, smooth and constant air flow to the device. Ensure a free exhaust, see the following pictures.
♦ To reduce transmission of vibration to the duct system, we recommend flexible connections from our accessory
range, see 5.2.4 Accessories, page 8.
