7 Installation
7.1 Safety information
• Check the surface before installation for load-bearing capacity.
• Consider all static and dynamic loads when selecting hoisting equipment and fastening components.
• Installation may only be carried out by adequately qualified persons, see Table 1: Qualifications
• Wear protective equipment during all work in the vicinity of the fan, see 2.2 Personal protective equipment.
• 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 installation to ensure freedom of motion
• Prevent the possibility of foreign bodies being drawn into the impeller during operation
• Remove all foreign material from inside the housing, if applicable
• Due to the potential for debris falling or collecting inside the unit during shipping or uncrating, personnel should avoid being
downstream of the airflow (near the exhaust point) during initial start-up
7.2 Preconditions
• Ensure that the fan and all its components are undamaged.
• Ensure that there is enough space to install the fan.

355.2 requirements.
• If using Post-Installed Mechanical Anchors (Adhesive), anchors must be tested and evaluated to ACI 355.4
requirements.
• If you are mounting to steel or wood frames, you must use vibration isolators.
Anchoring
:
• Contractor to anchor suspended unit to concrete with (1) 3/8-inch diameter concrete anchor capable of resisting 40 lbs (Safety Factor
of 4 equals 160 lbs) of tension load with minimum embedment of 2-inch at each of the (4) support points
• Refer to the anchor manufactures installation instructions for proper installation torque and embedment depth.
Positioning
:
• Position the fan unit so that the outlet is pointing in the planned direction of flow.
• Provide enough free space for inspection and maintenance work on the fan unit.
