7. INSTALLING CURTAIN TO BARREL
(CURTAIN ROLLED SO TOP SLAT IS SEEN)
1
Your locking straps will come attached to the barrel
in no particular place or direction as this is dictated
on installation
(fig.7.2)
.
2
Remove all straps from barrel by removing the
screws from the left collars of every pair and
keeping safe for later, then slide the left collar
across far enough so you have room to remove
the straps
(fig.7.3)
, remove straps and leave in a
safe place then remove all screws from the right
collars and keep safe for later.
3
Press and hold the down button until the barrel
stops on its own, this will be the bottom limit.
Using the manual override handle, wind the barrel
so it rotates in the closing direction until you have
clear access to the screw holes
(fig.7.4)
.
4
Measure 250mm from the head of the motor and
mark the barrel with a pen, measure 250mm from
the safety brake and mark barrel with a pen, then
measure to the middle of the door and mark barrel
with a pen.
5
Attached to the barrel are the White plastic covers,
you have 1 strap and 1 cover per pair of collars
(fig.7.5)
.
6
Slide the nearest ring to the end of the barrel to
line up with your marks and secure in place with
provided screw, then slide the other ring from
the pair over to this one leaving enough room to
be able to get the strap in
(fig.7.4)
. Spread the
remaining pairs of rings out evenly across the
barrel, if there is an odd number of pairs of rings
make sure the middle pair of rings are one either
side of the center mark.
7
Slide the locking straps on to the top slat of the
curtain trying to make sure they line up with the pairs
of collars you have laid out. The plastic covers are
provided to add extra protection against marking to
the back of the curtain as the roller door will be rolling
on itself, sometimes this can cause marking on the
back of the slats. You Do Not have to install these but
we would advise you do. The covers are installed on
the locking strap as in
(fig.7.6)
