MOUNTING OF DEVICE
NOTE:
1.
After installing the vent, it is essential to remove the protective film from the external
aluminium elements of the vent (pressing frames, pressing strip) and from the vent glazing
(PCA, sandwich panels, acrylic domes). Keeping the film on may cause permanent
discoloration of the parts and make future removal difficult. After removing the film,
loosen the self-drilling screws with the 5.5x38 EPDM washer of the pressing frame,
remove the residual film from beneath the washers and screw the screws back in.
2.
If the vent leaf is not delivered to site completely assembled, special care must be taken
when installing the polycarbonate panels. Damage to the film protecting the edges of the
polycarbonate plates will cause penetration of dirt into the PCA chambers which voids the
warranty.
3.
Mounting of the equipment must be carried out in compliance with all the necessary
safety rules, in particular relating to work at height or using appropriate personal
protective equipment.

Assembling the steel base
The base of the mcr S-THERM vent is delivered in parts and requires self-assembly. Individual sides of
the assembled base are connected with each other by special locks located at the edges.
Fig. 5 Side of the base A - vent width; B - vent length (dimension along the hinge).
NOTE: attaching the first of the sides to the structure before proceeding to assemble the vent
simplifies the assembly process and helps in maintaining right angles at the corners. Details of how
to attach the base to the structure can be found in chapter 5.2 and 5.3 (page 10).
