General safety information
♦ Installation may only be carried out by adequately qualified persons, details see Table 1 Qualifications, page 1.

♦ Abide by the system-related conditions and requirements of the system manufacturer or plant constructor.
♦ Do not dismantle or circumvent safety elements, or put them out of function.
♦ Move the impeller of the fan by hand before you install it in order to check that it moves freely.
♦ Provide contact and intake protection and ensure safety distances according to DIN EN ISO13857 and DIN 24167-1.
♦ Prevent the possibility of foreign bodies being drawn in.
♦ To reduce transmission of vibration to the duct system, we recommend flexible connections from our accessory

access for troubleshooting, maintenance and repair.
Important
Damage to the bearings or other parts of the fan can occur.
♦ Do not place a duct bend directly before or after the fan!
♦ Ensure a smooth and constant air flow to the device. Ensure a free exhaust. See Fig. 1 Straight ducts,
