Index
Use caution when operating the manual release with the door open since
it may fall rapidly due to weak or broken springs or an imbalanced door.
Do not use the manual release cord to pull the door open. The cord or
release may break under load.
Frequently examine the installation, in particular cables, springs and mountings, for signs of wear damage or imbalance. Do not use if repair or adjustment is needed since a fault in the installation or an incorrectly balanced
door may cause injury.
Each month check that the drive reverses when the door contacts a 40mm
(50mm for UK) high object placed on the floor. Adjust if necessary and
recheck since an incorrect adjustment may present a hazard.
Disconnect electric power to the garage door opener before making any
repairs or removing any side covers.
To prevent fire or shock hazard, do not expose the opener to rain or moisture.
To avoid electrical shock do not open the cabinet without disconnecting
the opener from the mains.

Site requirements
Radio interference
Radio interference can reduce the performance of garage door opener remote controls. Garage door remote controls␣ are required to operate in shared radio frequency bands. Regulations permit other users to continuously operate higher powered devices such as baby monitors or wireless headphones in these shared bands. These devices may cause radio interference that reduces the performance of your remote control. Switch off interfering devices if
possible.␣
Remote controls and receivers that operate on alternative frequencies are available at additional cost.
Electrical Power Supply
The opener is for Australian and New Zealand conditions of 220-240 Volts AC - 50 Hz.
There must be an earthed power point within 1.6 metres of the mounting position.
Tilt door clearances
The opener has been designed to fit most existing doors. The minimum installation clearance
from the garage ceiling to the top edge of the door during any part of the door’s travel is 100
mm.
The header bracket is to fit as close as practical above the top of the door, in the centre.
The door bracket is to fit at the highest possible point of the door, in the centre. The bracket
may be fixed vertically or horizontally to suit. A solid fixing point is required.
The overall length of the opener when assembled is 3150mm.
Clear space of around 600 mm is required behind the fully open door.
Sectional door clearances
For sectional doors using torsion springs the minimum allowable height from the top of the
closed door to the ceiling is 200 mm.

EDR4 1169 G 10/03
Garage Door
This opener is designed for a residential sectional door to 2.1 metres high or a one piece
tilting door to 2.4 metres high and 6.0 metres wide. For installation on taller doors see your
Merlin dealer.
Check that it is possible to raise the door by hand through the full height of the opening. The
door should operate smoothly, lifting up and down without the door or door mechanism binding. The door must not jam in the tracks.
A properly balanced tilt door will stop of its own accord at about the two thirds closed position. (Springs may need adjustment accordingly).
A properly sprung sectional door will either close of its own accord for the last 500 mm of its
travel or it will require a very light added force. If the door springs back, it is advisable to have
the spring tension adjusted. Do not attempt this yourself. Springs can only be adjusted safely
by a trained professional installer.
If in doubt about whether the door is suitable for automation consult an Authorised Merlin
Installer.
For sectional doors using tension springs the minimum allowable height from the top of the
closed door to the ceiling is 280 mm.
The header bracket is to fit 200-300 mm above the top of the door at the centre or directly
above the torsion bar.
The door bracket is to fit in line with the top rollers in the top panel. It may fit vertically or
horizontally. A solid fixing point is required.
The overall length of the opener when assembled is 3150mm.
Clear space of around 600 mm is required behind the fully open door.
Door Locks
Existing door locks must be removed or disabled. (The opener or the door can be damaged if
you try to open a locked door).

The assembled pole should be one segment shorter for a trackless tilt door. A shorter pole
flexes less during the opening and closing of the door. (Due to the lack of restraining tracks
the momentum of the moving door will tend to flex the pole.)

Installing the opener
EDR4 1169 G 10/03
WARNING Garage doors are under great spring tension. Do not attempt to adjust the spring tension on your garage door. Do not remove the springs. Merlin
Garage Openers Limited do not accept responsibility for damage or injury resulting
from installing this opener. Please read this manual fully before attempting installation. If you have any concerns please consider getting the opener installed by an
Authorised Merlin Installer.
STEP 1:
Check that there is a power point available and that there is adequate clearance
to mount the opener onto the door.
STEP 2:
Close the door.
STEP 3:
Mark the centre line of the door using a tape measure and pencil. Mark on the
7
header above the door and mark the door itself
at the top edges.
Header
Mark highest point
onto header
STEP 4:
Check the installation height of the opener.
Slowly open the door and observe the point at
which the top edge of the door is closest to the
ceiling. Measure the height of the top edge of
the door from the floor of the garage at this point.
You may have to clamp the door in position or
use blocks to hold it.
STEP 5:
Close the door again and mark this maximum
door height onto the header above the top edge
of the door. (On tilt doors with tracks, this maxiMaximum height
mum height might be as low as the top edge of
marking on header
the closed door.) If a sectional door torsion bar
or spring is in the way, mark the next clear space on the wall above. Extend the
door centre line up to intersect with the new height line.
Additional setup for trackless tilt doors (jamb fittings) only
Mark a horizontal line 300 mm above this maximum door height line. If there is insufficient
space above to allow the line to be 300 mm above the maximum height, then draw the line
80 mm below the ceiling. Extend the door centre line up to intersect with the new height line.
STEP 6:
Fit the header bracket to the header above the top of the door. The header bracket
must be attached to a rigid part of the garage such as a beam, with the bottom
edge of the bracket no lower than the height line that has just been marked. The
centre line of the door must align with the centre line of the header bracket. Two
lag screws are sufficient to hold the bracket to the header. Pre drill the screw
holes with a 1/4 inch bit.
STEP 7:
Place the opener assembly in the centre of the garage floor, resting on its styrofoam
or cardboard packing to protect the power head from scratching by the garage
floor.
STEP 8:
Lift the return pulley assembly up to the header bracket and attach by pushing the
clevis pin through both the header
bracket and the return pulley assemHeader bracket

have difficulty locating the joists. Try
either of these methods:
• Look for indications of the nails
that hold plasterboard to joists. You
may be able to locate nail positions
by imperfections in the joint compound or by using a magnetic stud
detector.

STEP 16: Connect one end of the straight door arm to the
trolley. Attach to the trolley using the short clevis
pin and its clip.

tilting doors. Usually the L arm is attached between
the door and the straight arm for use with sectional doors. Each installation
is a little different and you may have to shorten or re-drill the door arm in some
cases.
If you have not been able to attach the door bracket near the top edge of the door
then you may need to use the L-arm to prevent fouling of the door in the fully open
position.
CAUTION When the door is fully closed the door arm must not ever become vertical.
If the door arm is vertical then the opener can not sense an obstruction. The door arm
must remain at less than a right angle to the pole.
Disengage the trolley by pulling the red release cord straight down. Slide the trolley towards the door until the free end of the door arm reaches the door bracket.
Connect the free end of door arm assembly to the door bracket using the M8 bolt,
hex nut and nylok nut. The bolt goes through the door bracket and the lock nuts
lock either side of the door arm. After tightening the lock nuts the bolt must be
able to turn freely in the bracket.
STEP 17: Locate a convenient position to mount the pushbutton. The garage door should be
visible from this location. There should be no moving parts of the door or opener
within 1.8 metres of this button and the button should be placed higher than 1.5
metres from the floor.
If you are using a wireless pushbutton then follow the instructions on setting up wireless controls.
If you are using a wired pushbutton connect the pushbutton wire to the manual
control accessory terminals on the rear of the power head. Take care to keep
frayed wire ends from shorting across terminals.
Route wire from the power head to the location for the pushbutton. Fasten the
wire to the wall with the staples provided. Take care to allow some slack in the
wire between the first staple and the power head. Take care not to puncture the
10

nuts and washers. For a metal
door you may
prefer to use pop
rivets or Tek
screws.
insulation with the staples. Cut the wire to the length needed and strip approximately 10 mm of the insulation. Connect the wire to the two terminals on the
pushbutton. Mount the pushbutton to the wall.
CAUTION Keep the push button cable at least 600 mm clear of mains power cables if it is parallel to them. Do not run the push button wiring through the same
cavities in the wall as the mains power. Mains and low voltage wiring can cross
with no problems.
STEP 18: We recommend that you allow the antenna wire at the rear of the opener to
hang freely behind the opener. Generally the remote control transmitter will
be received from a longer distance if the antenna is visible.
STEP 19: Remove or disable any door locking mechanism. Failure to disable the locking
may result in damage to the opener or door.
STEP 20: Fit the light bulb and light cover into position and lock the cover securely with
its latch.
STEP 21: Manually raise the door until the trolley passes over the torpedo and engages. If
the trolley will not reach the torpedo then you must follow the appropriate procedure in the next section on setting door travel limits.
STEP 22: Attach the red release rope through the hole in the trolley release lever.
Ensure the release cord is threaded through the manual release warning card.
Setting the door travel limits

NOTE Repeated operation of the opener in a short period of time during setup may
trigger the thermal cutout of the motor. In this
case you will have to wait for approximately
five minutes for the motor to cool sufficiently
to continue the installation process. If the unit
has overheated you will hear the relays clicking in response to the transmitter or pushbutton
but the motor will not operate. After cooling
down, normal operation is able to resume.

STEP 1: Plug the opener into an earthed three-pin 220-240V outlet and switch on the power. The
opener’s courtesy lamp may turn on, or may flash for five seconds.
STEP 2: Remove the lamp cover by turning the catch on its underside. Remove the green control
panel cover to expose the setup controls. Observe the red and green indicator LEDs. The red LED
will stay on continuously at the fully closed position. The green LED will stay on continuously at the
fully open position. Identify the green operate button.
Ensure the door is engaged on the trolley.

The aim of these steps is to make the opener push in the direction that the door edge is
moving. Preferably the door edge is being forced upward slightly as the closing cycle begins.
You must adjust the top limit of travel so that if you sight along the fully open door the sight
line intersects the pole in front of the trolley - not behind the trolley.
If the door does not open far enough after setting the top limit of travel correctly
then it will be necessary to make some Sight line intersects pole

Setting the force sensitivity
STEP 1: Remove the lamp cover by turning the catch on its underside. Remove the green
control panel cover.
STEP 2: Identify the green and the red control knobs marked open-force and close-force.
Note: The opener can be set to either determine its own safe operating force level, or it can

WARNING The door is not safe for unsupervised operation until the force sensitivity has been be set.
be set to allow a deliberately greater amount of force to be applied to the door.
STEP 3: To set the force levels automatically, turn the control knobs clockwise and then fully
back anticlockwise. Ensure that the door is engaged to the opener. Then operate the opener
to move the door in a single unobstructed movement from one limit position to the other. If no
obstruction was sensed during this cycle then the opener will save the settings to memory.
Operate the opener to move the door back to the original limit position. Again, if no obstruction is sensed, the settings will be stored in memory.
STEP 4: To set the force levels at some higher level, rotate the control knob to some position
clockwise from the auto-setting point.
STEP 5: If a very light door is being operated, and if a very gentle closing force is required,
then set the option switch marked ‘Light door’ to the ON position. Note that on a heavier door
this option switch position may result in unintended detections of obstructions.
Setting up wireless controls
Wireless controls can operate the opener, or the opener’s courtesy lamp, by sending coded
radio signals. These coded signals use high-security code-hopping.
Wireless controls can be hand-held or fixed to walls, such as a wireless keypad, or a wireless
wall-switch.
Up to 20 Merlin wireless controls can be learned by the opener. After this, the 20th wireless
control is over-written in the opener’s memory.
All wireless controls can be deleted from the opener’s memory.
There is a learn button on the underside of the opener inside the lamp cover. The small
button on a Merlin M-122 wired wall-switch can also be used as the learn button.
If a setting is enabled in the opener, then it is possible to use any existing learned wireless
control as a learn button. (See separate section following.)
Remove the lamp cover by turning the catch on it’s underside. Remove the green control
panel cover to expose the setup controls. Identify the red learn button.
EDR4 1169 G 10/03
To learn a remote button to operate the opener:
Press the learn button for 1-2 seconds, until the courtesy lamp begins to flash slowly.
Press the desired remote button, wait 1 second, press the desired remote button again. The
courtesy lamp will stop flashing once learning is complete.
To learn one remote button to operate the opener and another to operate the
lamp:
Press the learn button for 1-2 seconds, until the courtesy lamp begins to flash slowly.
Press the desired remote button for control of the opener, wait 1 second, press the desired
remote button for control of the courtesy lamp. The courtesy lamp will stop flashing once
learning is complete.
To delete all remote controls from the opener’s memory
Press and hold the Learn (or setup on some models) button for eleven seconds, until the
courtesy lamp stops flashing. After six seconds it will flash fast as a warning. If you release
the learn (or setup) button during this warning period then the memory will not be wiped.
13
Adding the Merlin M102 noncontact beam sensor (Optional)
Non-contact beam sensors are optional but Merlin strongly suggests they be fitted for increased levels of safety. They may be fitted at any time. If sensors are fitted the opener will
only close when the sensors are fully functional and where their beam is unobstructed. The
door can open regardless of the sensor beam.
The sensors should be placed either side of the door opening, within 300mm of the door’s
opening, and within 100mm of the floor. Choose positions that will protect the sensors from
accidental impact or water. The receiving sensor should not be placed where it will be subjected to bright direct sunlight. The high level of Infra Red light in bright sunlight may temporarily prevent normal operation of the opener.
Switch off the power to the opener. Run the pair of cables from each sensor back to the
accessory terminals marked ‘beam sensor’ on the rear of the opener.
There is no need to connect the cables with
any particular polarity.
Switch the power to the opener back on. Aim
the sensors at each other using the adjustments
provided. When correctly aligned and unobstructed the sensor LEDs will stop flashing and
stay on continuously.
If the beam is obstructed or if the sensors are
not functioning then the door may still be closed
by holding the manual control button down for
at least two seconds, and keeping it held until
the door is closed.
Improving the door security
Manually operating the door
The garage door opener can be disengaged from the garage door to enable the door to be
operated manually.
14
EDR4 1169 G 10/03
If there is a clear gap above the top of the closed door it is possible in some cases for people
to gain unauthorised access to the garage after an opener is fitted. A piece of stiff wire can
sometimes be threaded through the gap to hook onto the safety release rope or lever. You
can improve the security by adding a strip of metal or wood over any gap to block access in
this manner.
WARNING Door may move suddenly when released.
Do not use the manual release cord to pull the door open.
The cord or release may break under load.
To disengage the opener
Pull the release cord down.
