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.
General safety information
♦ Installation may only be carried out by adequately qualified persons, details see Table 1 Qualifications, page 2.
♦ 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 7.
♦ Bear in mind that parts of the impeller may protrude out of the fan housing.
♦ If the product is installed with free suction or free discharge, install a protection grille to prevent injury from the fan
impeller. Make sure that the safety distance agrees with the standards DIN EN ISO 13857 and DIN 24167–1.
♦ Tightening torques of screw-type connections according to DIN 13.
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.
♦ Do not install the fan if the gap in the table (5.1.3 Air
gap between housing and impeller, page 5) is not
complied with.
♦ Ensure that the information on the name plates (fan
and motor) matches up with the operating conditions.
♦ A warning sign must be attached close to the air
outlet, stating that the air outlet must not be covered.
♦ Fit the fans in such a way that there is sufficient
access for troubleshooting, maintenance and repair.
Tests after long storage time (more than 12 months)
Note:
We recommend an inspection by the after-sales service of Systemair before commissioning.
Test the motor windings:
♦ Measure the insulation resistance of each motor winding against grounding at 500 V DC. The insulation resistance
must be > 10 mΩ.
Measures for an insulation resistance < 10 mΩ:
1. If the motor has drain plugs, remove them to allow any moisture to drain and replace them when the motor windings
are suitably dry.
2. Dry the motor in a warm dry airflow (typically 40 degrees Celsius).
3. Measure the insulation resistance of each motor winding against grouding at 500 V DC.
4. Repeat the aforementioned steps until the measurement outcome > 10 mΩ.
