Both one and two-car doors are installed in
the same manner.
Be sure all warning labels and tags are
properly affixed to the door and that the home
owner information is left with the purchaser.
GENERAL NOTES
WHO SHOULD
INSTALL THIS DOOR?
A minimum of two people must be
available for fitting. However due to the
weight and spring tension of larger doors,
we insist that three people or suitable
lifting gear be available for installation on
doors over 10ft wide or 9ft high.
PRE-INSTALLATION CARE AND HANDLING
• The door curtain must be handled with care at
all times
• The doors length must be supported in its
entirety during transport and handling
• The door must be stored on a flat DRY surface
• Packaging must not be removed until
instructed (at the correct step in the
installation)
Ensure that the area around the opening is
strong enough to support the door.

WARNING!
KEYPOINTS: ELECTRICALLY
OPERATED DOORS
Please read the instructions relating to the
installation of an electric motor prior to
commencing. Key guidance is summarised
here and repeated at the relevant step in the
installation.
• The installed door must operate efficiently when
used manually. Ensure sufficient clearance
between door and bracket to facilitate fitting of
motor (See Side Clearance, page 4).
• Turn off the power before making any
adjustments.
• Make sure the anti-coning collar is adjusted
and secure on the drum shaft to eliminate
sideways movement on the opposite side to
which motor is to be fitted.
• When installing the door, ensure the motor is
disengaged and the drum turns freely.
• Never engage the manual release with motor
running.
• The upper limit on the operator should be set
to stop the roller door, 30-40mm below the
guide stop, to avoid damaging the drive gears.
• Weight bar must be attached to bottom bar
with rivets/bolts.
This new GDS door has been designed for ease of operation, security and attractive
appearance with minimal maintenance. Performance of the door will be impaired if it
is installed incorrectly. Read these instructions carefully before commencing the
installation. Warranty is void if the door is not installed correctly according to
these instructions.

How much room do I need at the side of the garage opening?
The door is mounted onto brackets and the brackets must be set
in from the side of the garage opening by the minimum distance
to the outside edge of the bracket as shown in the table below.
Doors with a motor require extra clearance on the side the motor
is fitted - see table below.
To achieve the minimum side clearance you will need to cut the
ends of the door axle.
STANDARD DOORS
MINI DOORS
STRUCTURAL CONDITIONS OF OPENING:
The surface where the door is to be fitted must be flush and reasonably smooth. Small irregularities in
brick work will be acceptable. The lintel must not protrude backwards or forwards from the brick piers.

How much room do I need above the garage opening?
The door curtain is mounted on brackets above the garage opening and to
allow maximum drive through height, the minimum headroom required is
shown in the table below.
If insufficient headroom is available to allow the door roll to be fitted fully
above the opening, the door may be fitted projecting down into the opening
up to a maximum of 100mm without the need for a fascia. If the door
projects down by more than 100mm a fascia (not supplied) will be required -
see figure 1.
Note: 10mm more headroom is required to install the door than is needed
to operate the door once installed. If the available headroom is right at the
minimum, the bracket can be fixed 10mm lower whilst the door roll is fitted
and tensioned and then tapped up by 10mm once the door is installed to
give full clearance with no hangdown.
*The minimum headroom but will require bracket position adjustment
during installation to achieve full opening height. (see page 9)
**The minimum headroom that requires no bracket position adjustment
during installation to achieve full opening height. (see page 9)

Do not remove any wrapping, or steel protective outer
wrapping if fitted to your door, until instructed.
(a) Door package and its contents
should be checked for obvious damage before removal of
protective outer wrapping (If on your door).
(b) The door should only be fitted after any plastering of the area
has been completed. Plaster splashes will damage the pre-finish
on the curtain and cause premature wear of the nyloflex within
the guides.
(
c) The door must be fitted square and level irrespective
of the shape of the opening. On no account should any
compensation be made to suit an irregular opening

WARNING DANGER!
HIGH SPRING TENSION CAN CAUSE
SEVERE INJURY OR DEATH. REPAIRS
OR ADJUSTMENTS MUST BE MADE
BY 2 PEOPLE.
IMPORTANT NOTE: Pre-tension should
now be applied to the springs by
turning the curtain roll approx 2 turns
forward for standard door and 3 turns
for mini doors
The amount of pre-tension required
may vary with individual doors and
applications - See adjustments section
on page 16 and 17.
PRE-TENSION:- Do not cut the
CARDBOARD bands that hold the
door curtain in a roll. However, ,
if the door has a protective steel
wrapping, cut the bands and remove
this before you pre-tension.
Carefully cut the wrapping to expose a
small portion of the bottom rail. Hold
the door by the bottom rail before
removing all wrapping. DO NOT
RELEASE THE BOTTOM RAIL. The door
will have a strong tendency to rise,
WHICH IF UNCONTROLLED COULD
CAUSE SERIOUS DAMAGE OR INJURY
DUE TO SPRING TENSION. The door
must be held until both guides are
securely fixed in place.
NOTE: Knife marks or cutting of the
bottom seal or the nyloflex webbing
voids the door warranty
ENSURE THE DOOR CURTAIN IS
CENTRED. IF ADJUSTMENT IS REQUIRED,
CENTRE THE DOOR ROLL BY LIFTING
THE CURTAIN AND AXLE TOGETHER
A person must hold and control

adjustment - figure 3).
CONING: Check that the door rolls up
evenly and squarely with the ends of the roll,
if it rolls out unevenly (cones out at one end)
repeat FINAL adjustment section on page 16.
DOOR TENSION: The door is now
installed. Lower the door curtain to the half
open position to check that the spring tension
is in balance. From this position the door
curtain does not rise or lower of its own accord
when released.
The door should be slightly over tensioned
during this running in period. i.e. when put
to the ground it should want to rise 25mm -
40mm unless locked down.

If the door is very difficult to close during the
last 600mm of travel, check that the guides are
fitted in the correct relationship to the brackets
and that the axle is the correct distance from
the wall. (see step 3, page 10, 11). One or
both will be incorrect, thereby increasing lead
angle into the mouth of the guides, making the
door difficult to close.
CONING (SEE FIGURE 4)
If the curtain rolls up unevenly (cones out at
one end) and the bottom rail appears out of
parallel with the door roll and guides, check
for the following:
(a) Brackets not level.
(b) The axle is not the same distance back from
the wall at each side.
(c) Axle not correctly centralised in roll.
If the brackets are level and the axle distance
from the wall is equal at both sides, remove
the coning by moving the axle through the roll
in the opposite direction to the coning.
This operation should be done by minimum of
two people and ensure the door is fully rolled
up to minimise spring tension before starting.
CONING ADJUSTMENTS
Follow the steps in final spring tension
adjustments, (see next section) up to (e) where
it states “to increase tension”. Do not rotate the
axle unless spring tension is to be changed.
While still retaining a firm hold on the axle to
prevent axle rotation using a pipe wrench, the
axle should be lightly tapped in the direction of
the coning (See figure 4). Move no more than
20mm at a time. Then follow the steps and
secure axle. After adjustment the door needs
to be opened and closed 2-3 times to settle
the new alignment. You may need to repeat
this step a number of times.
If coning persists, fitting of an anti coning
collar/exhaust clamp (1 3/8”/35mm) may be
necessary. Note the side to which the door is
coned and, with the door closed, fit an anti
coning collar onto the axle tight against the
boss of the drum wheel to prevent movement
to the left or right as the door opens or closes.

MAINTENANCE
The following suggestions will keep the
door working efficiently.
1. Do not grease or oil the guides.
2. Periodically clean the inside of the
guides with white methylated spirits or
similar and spray with silicone spray or
car/furniture polish.
3. It may be necessary to lubricate the
locking mechanism via the key hole
using graphite dust lubricant if operation
becomes difficult.
4. Your door should be washed with a
quality car shampoo at least every 2
months to prevent the build up of dirt,
salt and other corrosive substances. If
your door is installed within 2 miles of
the sea, your door should be cleaned in
this way at least monthly.
WARNING! DANGER! HIGH
SPRING TENSION CAN CAUSE
SEVERE INJURY OR DEATH. REPAIRS
OR ADJUSTMENTS MUST BE MADE
BY TWO PEOPLE USING PROPER
TOOLS AND INSTRUCTIONS.

FINAL SPRING TENSION ADJUSTMENTS
(SEE FIGURE 6)
AS A PRECAUTION, ATTACH A PIPE
WRENCH AT THE OPPOSITE END TO
BE WORKED ON AND ENSURE IT IS HELD
TIGHTLY BY ANOTHER PERSON.
(a) One ‘U’ bolt clamp should be selected to
loosen first and the other side should remain
fully tightened. The remaining tight ‘U’ bolt
clamp will retain the existing tension when
the door is fully open (rolled up). However,
as a precaution a pipe wrench must be also
be attached to the axle at the opposite side to
be worked on and held tightly by one of the
installers.
THIS OPERATION SHOULD NOT BE
ATTEMPTED WITH THE DOOR IN THE
CLOSED POSITION AS THE TENSION IS
VERY MUCH GREATER AND COULD LEAD
TO DAMAGE OR SERIOUS INJURY.
(b) Loosen but do not fully remove the selected
‘U’ bolt clamp.
(c) One person should then grip the axle on
that side firmly with an 18” pipe wrench.
(d) The other person should then move to the
other end of the door roll and with an 18”
pipe wrench, grip the axle firmly. Loosen but
do not fully remove the other ‘U’ bolt clamp
until the axle is free.
(e) To increase tension pull down on the pipe
wrench and to decrease tension allow the pipe
wrench to move up (see figure 6).
(f) Fully tighten adjacent ‘U’ bolt clamp while
holding tension with a pipe wrench. Do not
release pipe wrench until ‘U’ bolts are tight.
(Ensure that it never slips as this would cause
loss of tension and possible injury or damage
to door).
