CAUTION:
• Installation of the unit and accessibility must be compliant with the local regulations. Ensure that all access equipment allow
maintenance operation in safety (electrical cabinet, main switch, panels, filter, refrigerant circuit…); this recommendation is
valid for installations in general and in particular for return and curbs.
• It’s advised to fix curbs and roofcurbs to the unit
Levelling adjustable roofcurbs
The levelling operation must be done prior to put the unit on it.
Above all, ensure that all the adjustable returns are facing outward. They could be turned inside-out for transport.
Place the roof mounting frame on the trimmer beam by first lining up the inlet and the outlet opening.
After levelling the frame, secure the adjustable returns on the trimmer.
IMPORTANT NOTE: Securing the roofcurb
When the roofcurb is correctly positioned, it is essential to secure the assembly with a disconnected stitched welded seam (20 to 30
mm every 200 mm) or self-taping screws (every 200mm) along the outside.
