8.1 Safety information
General safety information
♦ Installation may only be carried out by adequately qualified persons, details see Table 1 Qualifications, page 1.
♦ Wear protective equipment during all work in the vicinity of the fan, details see 2.2 Personal protective equipment,
page 2.
♦ 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.
♦ 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 fast clamps from our accessory range, see
chapter Accessories.
8.2 Preconditions
♦ Ensure that the fan and all its components are
undamaged.
♦ Ensure that there is enough space to install the fan.
♦ Protect against dust and moisture when installing.
♦ Ensure that the information on the name plates (fan
and motor) matches up with the operating conditions.
♦ Fit the fans in such a way that there is sufficient
access for troubleshooting, maintenance and repair.
Warning: “Unintended” start-up of the unprotected impeller!
If the unit is plugged in and the fan has been removed from the duct system or the protective grille is
not mounted on the fan, the impeller may start, resulting in injury.
♦ Unplug the unit immediately.
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,
