4. TRANSPORT AND DELIVERY
mcr-PROLIGHT type C, E, NG-A vents are delivered assembled, but in specific cases
(additional external processing, low base heights, etc.) they may be delivered as assemblies
and subassemblies. Air deflectors are always delivered separately. This is due to the necessity
of protecting individual vent elements from transport damage, and ensuring safety in road traffic.
Unloading should be performed under the supervision of a person authorized by the
manufacturer, using generally accessible handling equipment, or manually, observing all
applicable SHE principles.

5. DEVICE INSTALLATION
The device must be installed in observance of all the applicable SHE principles, particularly
those related with working at height, using adequate personal protective equipment.
The vents must rest on the roof's structural elements such as: purlin, trimmers, structural sheet,
reinforced concrete plinth. Any elements causing collision with the vent leaf at full opening
range should be removed.
The vents may be installed on roofs of steel, concrete or wooden structure. The device base
has a protrusion (shelf) in its lower part, allowing to rest and fix the vent to the supporting
structure.
Fixture elements should be selected depending on the supporting structure's making, according
to the below table. Fixtures should be installed at 50-60 cm spacing.
