Delivery conditionF.2
With the exception of some models SR30 with option ‘SE’,‘BR’ or ‘SP’ delivered in an open wooden crate, all spring reels are delivered in a card-
board box. The reels can be delivered in different configurations.
Before starting installation, the delivery must be checked for completeness and defect-free condition.
Damage to components must be reported immediately!
Check that the delivered reel corresponds to the implementation and intended use, and in particular
its winding direction. The winding direction is the opposite of the pre-tensioning (bending) direction
indicated on the flank of the cable drum (yellow label) 
Installation of the reelF.3
HandlingF.3.1
If the installation of the reel cannot be done manually, place two
textile slings according to the opposite figure.
The load must be balanced to avoid any slippage of the
slings.
Only use slings in good condition and of suitable length: slings
that are too short can cause deformation (cable drum flanges).
When handling, be careful not to bump the flanges of the cable drum: deformed flanges do not allow a correct positioning
of the cable on the drum.
