6.1 Installation of side panels
There are two types of head profiles:
•SUPPORTING:
This profile is used when the head profile can be completely
secured to a bearing structure in metal or masonry without
any significant deformation.
•FREE-STANDING:
This is the aluminium profile which, when assembled on the
telescopic support profile, provides the free-standing
characteristic to the head profile. It is used when the head
profile cannot be completely secured on a bearing structure.
Telescopic profile - securing it to the wall
•Establish the exact location of the head profile considering
the overall dimensions of fig. 7. The head profile must be
secured parallel to the floor.
•To begin with, fit the head profile on a vertical slot at one
end and on a horizontal slot at the other end (using M8
screws and appropriate expansion plugs), and level parallel
to the floor.
Secure at the centre, firmly lifting the head profile to align the
three securing points. Carry out the remaining securing
operations, alternating vertical and horizontal slots (fig. 7).
Free-standing profile - securing it to the wall
•Establish the exact location of the free-standing profile
considering the overall dimensions of fig. 8. The head profile
must be secured parallel to the floor.
•To begin with, fit the free-standing head profile on a vertical
slot at one end and on a horizontal slot at the other end
(using M8 screws and appropriate expansion plugs), and level
parallel to the floor.
Secure at the centre, firmly lifting the head profile to align the
three securing points. Carry out the remaining securing
operations, every 20 cm on the vertical slots as shown in figure
8.
Free-standing profile - securing with side brackets
The automation head profile with the free-standing profile
can be secured at the two ends by using the side brackets
accessory (fig. 9).
•Establish the exact location of the head profile considering
the overall dimensions of figs. 3 and 8.
•Loosen the end tie-rods securing the three profiles in order to
facilitate fitting the side plates.
Secure the side plates on the head profile as follows:
•Position the small pates in their seats and secure the side
