12.4 - Heat recovery wheel module (BW and RW
assemblies)
Transport and handling
The module with the heat recovery wheel and its support bed are
supplied disassembled with the unit, for installation on site.
■ The module can be handled safely by using a forklift truck. The
base frame features guide rails to accommodate the forks of
the fork-lift truck. These guide rails avoid any slippage.
■ For transport and lifting up to the roof using a crane, a rocker
arm as well as approved slings must be used. These slings are
attached on the grips fi tted to the cover of the module.

■ First, the fresh air housing (1) is connected. Follow the steps
detailed in paragraph 12.3.
■ Next, the front panel (2) is secured using 8x40 hex screws.
