fig.2.2
fig.2.3
1 On unpacking your RD77 kit you will see that the
barrel has the motor in 1 end (fig.2.1) and the
adjustable bung end the other (fig.2.2).
2 If your header plates have come separate from the
casing please drill though the ‘L’ shaped front case
and the flange on the header plate at each end,
then secure ‘L’ shaped front case to the flange with
at least 4 rivets (2 per face) (fig.2.3).
3 Remove screws from header plate (fig.2.4)
and keep them safe for later.
4 Round shape safety brake (fig.2.5): Loosen screw
at the end of adjustable bung end to allow it to slide.
Check the position of the safety brake to make sure
that the big silver allen key bolt is running parallel to
the shortest edge near the inlet wheel as in (fig 2.5).
Square shape safety brake (fig.2.6): Make sure
the cable is coming out of the top of the safety break
in line with the long flat side and the red curve on
the safety break (fig.2.10) is going from fat to thin
towards the front case. Loosen screw at the end of
adjustable bung end to allow it to slide.
5 (For IMO system) remove winding stem from your
winding handle where it has been taped securely
(fig.2.8.IMO). (For EMO system) remove metal
sha via the plastic circlet (fig.2.9.EMO).
6 With the top case sitting flat & the locating stem
facing up (fig.2.3), insert the barrel into the
case, whilst one person holds the motor end
extend the adjustable tube end so it goes into
the safety brake as far as possible. Round safety
break (fig.2.11) Square safety break (fig.2.12).

7 Remove the screw from the end of the
winding stem and keep safe for later, insert
the stem into the head of the motor, then
rotate so the motor can be secured with
the 4 screws onto the header plate through
the 100x100 metal plate, making sure that
the motor wire is facing down towards the
case (fig.2.7), remove the winding stem and
keep safe for later.
8 There is a cable coming from the brake, this
may vary in length and depending on your
width of opening a extension cable may need
to be added, if so connect as follows; Brown
to Brown and Blue
to Blue.
9 Place the plastic wand from your fixing kit
into the hole in the head of the motor so it
sticks up past the flange of the header plate,
then using this as a guide drill a 10mm hole
through the middle of the flange for the
winding stem so it lines up with the hole
in the motor, then insert the winding stem
through the hole and back into the motor
before securing inplace with the screw.
Please check the barrel is all the way to the
motor head as (fig.2.7). Then check the
opposite end where the tube end is and if
fully extended, slide the locking collarall the
way up to the bung and tighteninto place (we
advise using a thread lock adhesive to hold in
place) as (fig.2.11) or (fig.2.12).

3. PREPARING GUIDE RUNNERS
FOR INSTALLATION
1 We use 2 types of guide runners
whichever is supplied with your kit will
be marked with the letter ‘F’ to indicate
the front, as seen in (fig.3.1 type 1) and
(fig.3.1 type 2). This marked face will
fit against the wall for a standard back
fixing or face out of the opening for a
between fixing (fig.3.5).
2 Your guide runners are supplied
oversize and need to be CUT down
to size, check the lintel is level then
measure from floor to lintel both sides
before referring to (fig3.6) and making
the cuts as necessary (for best results,
install the guide runners so that the cut
end is against the floor).
3 Offer both cut guide runners up against
the walls they will be fixed to and mark
the fixing points, either on the flat face
for a behind fixing (fig.3.3) or for a
between fixing in the opening (fig.3.4).
For best results these should be as
follows;
A Top fixing between 50mm to
100mm down from the top of the
guide rail.
B Bottom fixing 50mm to 100mm
up from the floor.
C Marking as many fixings as
necessary but must be at least
two extra fixings. Spread these
evenly between the two already
marked points on the guide
runners so that you have a secure
fix.
D Drill a 7mm hole all the way
through each of the marks
and then drill a 10mm hole to
countersink through the first layer
only so you can get the screw
head through.

4. INSTALLING HEADER ASSEMBLY
1 Place your hop ups / step ladders and one guide runner
each side of the opening.
2 With one person each end, lift the header assembly by the
header plate up and then guide the locating stem at each
end into the hollow section of guide runners. If there is
not enough room to simply drop the locating stem in, you
can angle the header plate (fig.4.1). Make sure to insert
the stem fully into the guide runner (fig.4.2).
3 Lift the whole unit flush into place and check that the top
box and guide runners are plumb, level and square.
4 Drill your fixing through the top hole in the guide runners
and secure into place (fig.4.3).
5 Check the case and guide runners are still level and square,
then proceed to drill your remaining fixings, remembering
to check the guide runners are square and plumb aer each
fixing.
6 Once the guide runners are fixed you will need to secure
the top box with 2 fixings each side. This is best done by
drilling through the end flanges of the header plate for a
behind fix, or sideways through the header plate itself if a
between fixing (fig.4.4), PLEASE NOTE: The large cut outs
in header plate are only for use with larger fixings e.g.
shield anchor or coach screw.
7 Check to make sure all fixings have not caused the front
fascia to be pulled in, as this will rub against the slats
causing damage and scratching to the face.

6. INSTALLING CURTAIN TO BARREL
(CURTAIN ROLLED SO BASE RAIL 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.6.1).
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.6.2), 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.6.3).
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.6.4).
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.6.3). 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 Place a tool box into the opening for the curtain to sit
on to, we recommend placing something so onto
the barrel for this stage to reduce damage to the back
of the curtain. with 1 person each side li the curtain
up and carefully feed it over the barrel into the guides
(fig.6.5) lowering all the way down so it sits on the
tool box.
8 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.

8. SETTING MOTOR LIMITS
(STANDARD MOTOR)
1 Curtain already in guides: Press and hold the up button on
receiver box so the curtain starts to roll up around the barrel,
keep going until the motor stops or press the stop button if
you get to 300mm (roughly 4 slats) from the top, then remove
item from opening that was used to sit the curtain on.
Curtain in arms: Press and hold the up button on receiver
box so the curtain starts to roll up around the barrel, Making
sure to check the curtain rolls up away from the guide run-
ners, the person with the curtain in their arms needs to let
the door unroll and make sure it doesn’t drop when you get
to the last slats, keep going until the motor stops or press
the stop button if you get to 300mm (roughly 4 slats) from
the top, then use the manual winder to wind the curtain the
last bit until it has passed the guides. Once it has passed the
guides, wind the door back down so 4 slats are in the guides.
2 There are 2 straight line arrows on the head of the motor,
these are to show you the direction that the limit nearest to
it controls, place the plastic wand in to the limit with the
arrow pointing towards the front case (fig.8.1 & fig.8.2)
and turn 10 times in the negative direction, negative (–) and
positive (+) are marked on the head of the motor and are the
same direction for both limits.
3 Press and hold the up button and the curtain will travel to
the top and should stop on its own, if the curtain gets
to 100mm from the top of guide runners (roughly 2 slats)
and hasn’t stopped, then stop the curtain and take
it back down to 300mm from top of guides (roughly 4 slats)
turn again 15 times in the negative direction, take the curtain
up and repeat until the curtain does stop before it gets to
100mm from top.
4 For Somfy Rollixo ONLY: Turn the limit towards the positive
direction (+) and aer each couple of turns, use the buttons
on the control box to close the curtain slightly before opening
it again each time moving a little higher. Keep doing this until
there is one full slat in the guide runners. Take the curtain
down a little and back up to make sure you are happy.
For every other control system: Whilst holding the up
button turn the wand in the positive direction and the
curtain will start to judder up, keep going until there is only
the last slat in the guides. Take the curtain down a little and
back up to make sure you are happy.

5 Move the plastic wand in to the other limit with the arrow pointing
towards you and turn 10 times in the negative direction.
6 Press and hold the down button so the curtain closes, it should stop
before it touches the floor if this is not the case take the curtain back up
300mm o the floor and turn again 15 times in the negative direction,
take the curtain back down and repeat until the curtain does stop before
it reaches the floor.
7 For Somfy Rollixo ONLY: Turn the limit towards the positive (+) direction.
Aer each couple of turns, open the curtain slightly and then close it each
time closing a bit further.
For all other control systems: Whilst holding the closed button on the
handset turn the wand in the positive direction and the curtain will start
to judder down.
8 Keep repeating until the curtain is fully compressed and pressure is
applied from the top via the locking strap. The ideal finishing position of
the curtain is to have the top of the guide runner exactly in the middle of
the very top slat (fig.8.4) but no more than 1 full slat above the top of the
guide runner (fig.8.3) if there is more than this you will need to remove
the extra slats.
9 Close the curtain down to make sure it doesn't catch anywhere and the
front case is not bowed in so as to rub on the curtain during operation,
then seal down the sides and along the top case as needed (silicone
sealant is recommended).

you get to the last slats, keep going until the whole curtain
is up passed the top of the guide. Once passed the guides,
wind the curtain down so 2 slats are in the opening, then
press and hold the up button on the receiver box again so
the curtain goes up. Stop the curtain when 1 full slat is le in
the guide runners.
4 Using a screw driver press in and release the coloured limit
for the open / up direction as per diagram (fig.9.5).
5 Run the curtain down until fully compressed and pressure
is applied from the top via the locking strap. The ideal
finishing position of the curtain is to have the top of the
guide runner exactly in the middle of the very top slat
(fig.9.6) but no more than 1 full slat above the top of the
guide runner (fig.9.7) if there is more than this you will
need to remove the extra slats.
6 Using a screw driver press in and release the coloured limit
for the close/down direction as per diagram (fig.9.5).
7 Run the curtain all the way to the top limit to check it stops
in the correct position, then run the curtain all the way to
the bottom limit to check it stops at the correct position
and if happy, replace the cap to cover the limits (fig.9.1). If
the limits are incorrect repeat procedure from start.
8 Close the curtain down to make sure it doesn't catch anywhere
and the front case is not bowed in so as to rub on the curtain
during operation, then seal down the sides and along the top
case as needed (silicone sealant is recommended).

3 Clean up any loose or rough edges (fig.10.4).
4 Lift the back case up as close to the winding stem
and gland as possible, hook the back case into
the top lip where the two cases meet (fig.10.5)
and slide across to go all the way to the edge of
the header plate, making sure when it is all the
way over that the whole of the two cases are
slotted together.
5 With the self-tapping screw provided, secure
through the back case into the bottom flange
of the header plate on both sides (fig.10.6).
