assemblies)
12.4.1 - Transport and handling
The module with the heat recovery wheel and its support bed are
supplied disassembled with the unit, for installation on site.

base frame features guide rails to accommodate the forks of
the fork-lift truck. These guide rails avoid any slippage.

arm as well as approved slings must be used. These slings are
attached on the grips fi tted to the cover of the module.
