Transport and handling
The module with the rotary heat exchanger 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.
