APPLY ONE HALF OF THE COUPLER TO EACH END OF THE CHAIN AND THEN LOCK BOTH COUPLER
HALVES.
If a fixed tensioning system
– pulley – is used:
The pull cord length must be limited as follows:
1) If installation height (H0) is not specified, and
i) if the blind height (H) is less than or equal to 2.5 m, the length of the pull cord(s) (H2) shall be less than or equal
to 1 m (see Fig.
): H2 ≤ 1 m.
ii) if the blind height (H) exceeds 2.5 m, the length of the pull cord(s) (H2) shall be less than or equal to the height
of the blind minus the value of 1.5 m (see Fig. 6): H2 ≤ H - 1.5 m.
2) If installation height (H0) is specified, the distance from the floor to the bottom part of the pull cord(s) (H1) shall be
at least 1.5 m (see Fig.): H1 > 1.5 m.
b) The distance between two loop strands shall not exceed 50 mm at the output from the fixed tensioning device.
THE PULLEY POSITION SHALL PREVENT EXCESSIVE CHAIN TENSIONING AND THE CHAIN MUST NOT COME
OFF!
WHEN PULLED APART, THE GAP BETWEEN THE CHAIN STRANDS SHALL NOT EXCEED 50 mm!
Cord controls:
The blinds shall meet the following requirements:
If fully pulled up, the pull cord(s) length shall be limited (the two wheels shall be located as follows):
If installation height (
H
0
) is not specified, and
i) if the blind height (
H
) is less than or equal to 2.5 m, the length of the pull cord(s) (
H
2
) shall be less than or equal
to 1 m (see Fig.):
H
2
≤ 1 m.
ii) if the blind height (
H
) exceeds 2.5 m, the length of the pull cord(s) (
H
2
) shall be less than or equal to the height
of the blind minus the value of 1.5 m (see Fig.):
H
2
≤
H
- 1.5 m.
