7.1 Safety information
Danger: Risk that the fan does not work in case of fire.
♦ Use installation material with fire resistance classes that meet temperature requirements.
Warning: Danger from falling fan or fan parts.
♦ Check the surface before installation for load bearing capacity.
♦ Consider all static and dynamic loads when selecting hoisting equipment and fastening components.
♦ Tighten all screw-type connections according to the data, see Table 14 Tightening torques according to DIN 13, page
15.
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.
♦ Safety elements may not be dismantled, circumvented or deactivated.
♦ Move the impeller of the fan by hand before you install it in order to check whether that moves freely.
♦ 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
range, see 5.2.3 Accessories, page 8.
♦ Bear in mind that parts of the impeller may protrude out of the fan housing.
7.2 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.
7.3 Tests after long storage time (more than 12 months)
Note:
We recommend an inspection by the after-sales service of Systemair before commissioning.
