C) LARGE COUNTER BALANCED DOOR
By “large counter balanced door” we mean a counter balanced door wider
than 3.5 m. or higher than 2.5 m. In this case you would require 2 Scuti units.
Follow the steps shown in B) for both units fitted to the outside edges of the
door. Do not mechanically connect the two units together (Fig. 5).
D) FOLDING COUNTER BALANCED DOOR
The installation is similar to what has been described before. The only
differences are as follows:
- you need short side fixing brackets; these must be specified in the
purchase order;
- the differential shafts and bearings (No 6 - Fig. 2) must be positioned at
least 5 cm under the door hinge;
- the bracket (No 4 - Fig. 2) must be attached to the door frame in line with
the top hinge of the door or as near as possible.
E) COUNTER BALANCED DOOR WITH HORIZONTAL TOP GUIDE
TRACKS
The installation instructions are the same as for doors without top tracks
(see B).
In addition to this you must adhere to the following directions:
- position the unit with the rotating differential shafts in the middle of the
height of the door and the side fixing brackets central on the width of the
door;
- the bracket (No 4 - Fig. 2) must be fitted beside the top track or as close as
possible to the junction of vertical and horizontal tracks.
F) SPECIAL APPLICATIONS
If you have an application where you cannot fit the telescopic arms in line
(as shown in Fig. 8), follow these directions:
- set the unit on the door with the rotation shaft at least 5 cm higher than the
hinge of balance arm and door frame;
- the bracket (No 4 - Fig. 2) must be either fitted on the balance arm or the
door frame, anyway close to the top hinge of the balance arm;
- modify the tap section of the telescopic arm, forming an elbow as
shown in Fig. 8; when the door is fully open both arms should be parallel.
G) FINAL CHECK
The weight of the unit together with all its installation accessories will alter the balance of the door. It is necessary to increase
the original counter balance by approximately 8 10 daN.
The optimum balance is achieved when the door works smoothly in both directions.
