2.3 Mounting the flange and the suspension tube to the ceiling
Before mounting the flange and the suspension tube, assembly work on the ceiling (setting the dowels or
mounting the ceiling anchorage ring and possibly mounting the intermediate flange) must be completed
and all pre-assembly work finished.
Type with ceiling anchorage ring
•
Screw three nuts
B
(each 120°) to the plate of
the ceiling anchorage ring, holding the other
three nuts 0,5cm away from the plate, unscrew
nuts
A
.
•
Position six washers
C
and six insulating wash-
ers
D
on the flange.
•
Position the flange with suspension tube on the
threaded bolts and adjust it to the required
height using three nuts
A
and washers
C
, insu-
lating washers
D
, and retaining washers
E
(each 120°).
Note: Washers C, insulating washers D and
retaining washers E must be put on the
flange in the same order as shown in the
figure.
•
The three-point mounting allows a simple verti-
cal adjustment of the suspension tube.
Vertical adjustment is very important and
must be carried out with great care.
If the flange with suspension tube is not in the cor-
rect vertical setting, the support arms of the lamp do
not remain precisely in the proper position, they
could turn away and would therefore require exces-
sive braking.
•
Then position from above all six nuts
B
gently
against the flange.
•
Screw on the remaining three nuts
A
with
washers
C
, insulating washers
D
and retaining
washers
E
and tighten all six nuts equally
cross-wise with a torque wrench (25 Nm).
Note: Washers C, insulating washers D and
retaining washers E must be put on the
flange in the same order as shown in the
figure.
•
Verify balance with a spirit-level.
