12.3 - Heat recovery wheel module (BW assembly)
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.
Installation
■ The fresh air housing (1) is factory-installed.
■ First, the front panel (2) is secured using 8x40 hex screws.
■ Then, in models 100 to 170 the support bed (3) is fi tted. This
is fi xed to the panel using 4.8 self-tapping hex screws on the
sides and 8x40 hex screws on the front. The recovery module
is positioned on the support bed but without eff orts on it.
Note: On models 180 to 280 there is no such support bed.
■ Next, the module is coupled to the unit. Do not remove the fork-
lift truck until the module is not secured to the unit.
■ The module is secured to the unit using 8x40 hex screws. To
do this, the side panels must be removed from the module. The
right-hand panel (front view) is secured using M6 Allen screws,
while the left-hand panel (4) incorporates dual locks.
Note: Check that the locks are not blocked. Open the locks with
a 4 mm Allen key (anticlockwise).
■ In models 100 to 170, the module is screwed to rest on the
support bed using 8x40 hex screws on both sides.
■ Finally, raise the hoods (5) and follow the assembly procedure
described in paragraph 12.1.
Note: All the screws required for this assembly are supplied secured
on the module and the support bed.
