Further prerequisites are a completed maintenance plan with no gaps and a commissioning re- port. Systemair will require these in the case of a warranty claim. The commissioning report is a component of this document. The maintenance plan must be created by the operator, see section 12.2 Maintenance, page 13.
Description | Unpacking When opening the transport packaging, there is a risk of damage from sharp edges, nails, staples, splinters etc. ♦ Unpack the fan carefully. ♦ Check the fan for obvious transport damage. ♦ Only remove the packaging shortly before assembly. Transport Safety information Warning: Electrical or mechanical hazards due to fire, moisture, short circuit or malfunction.

The ball bearing of the motor and the balanced impeller may be damaged by forceful impacts. ♦ Attach the impeller and/or the shaft extension to the shaft or the rotor without forceful impacts. ♦ Do not separate the impeller and the hub. They were balanced as one unit by Systemair. Note: The hub can be heated for easier assembly and disassembly, for example with a hot-air blower.
