Installation Instructions
Direct Unit Mounting
The previous directions are the preferable way to mount the new rear grill. The unit’s performance is slightly better and
the possibility of draughts is reduced. As a last resort, direct mounting of the grille to the unit can be considered.
Note: The grille must be installed prior to inserting the unit into the sleeve.
