With horizontal collector position
> Attach the lower ridge plate couplings
(¬ Table 5.1/5.3, Item 16) above the
collector:
– one on the external edge
(max. 150 mm from the edge).
– in the centre of the collector
(1066 mm from the edge).
– one per collector joint (central).
> Make sure that the lower ridge plate cou-
plings are resting on the collector frame
slot (1).
> Slide a support board (¬ Table 5.3,
Item 18) through the straps on the lower
ridge plate coupling (2).
> Join the lower ridge plate couplings to the
support board with two No. 2 screws each
(¬ Table 5.2/5.4) using the Torx bit to
prevent it from slipping (3).
> Screw the lower ridge plate coupling at the
top to the roof batten (4).
> Remove the protective film from the ridge
plates (¬ Table 5.1/5.3, Item 14, 15, 10).
> Slide the ridge plates (1) over the lower
ridge plate couplings.
> Make sure that the ridge plates are above
the side sections and slip into the corre-
sponding rail (2).
> Start with a left hand ridge plate
(¬ Table 5.1/5.3, Item 14).
> If there are three or more collectors next
to one another, fit the corresponding
number of centre ridge plates
(¬ Table 5.1/5.3, Item 10) an.
> To finish, fit the right hand ridge plate
(¬ Table 5.1/5.3, Item 15).
> Fasten all the ridge plates to the roof
battens with the No. 1 screws
(¬ Table 5.2/5.4) using the Torx bit (1).
> Take the required number of upper ridge
plate couplers (¬ Table 5.1/5.3, Item 11).
An upper ridge plate coupling must be
screwed between each left hand, centre
and right hand ridge plate.
> Fasten all the upper ridge plate couplings
(2) above the ridge plate joint with two
No. 4 screws (¬ Table 5.2/5.4), Item (3)
in Fig. 5.34, and one No. 1 screw
(¬ Table 5.2/5.4), Item (4) in Fig. 5.34,
using the Torx bit.
