SAVE THESE INSTRUCTIONS

Warning: If your garage has no service entrance door, a E1702M outside quick release must be installed. This accessory allows manual operation of the garage door from outside in case of power failure.

BEFORE YOU BEGIN:

1. Look at the wall and ceiling above the garage door. (The opener and header bracket must be securely fastened to structural supports.)
2. Do you have a finished ceiling in your garage? If so, a support bracket and additional fastening hardware (not supplied) may be required.
3. Do you have an access door in addition to the garage door? If not, model E1702M Outside Quick Release Accessory is required. This accessory allows manual operation of the garage door from outside in case of power failure.
4. Complete the following test to make sure your garage door is balanced and is not sticking or binding:

• Lift the door about halfway. Release the door. If balanced, it should stay in place, supported entirely by its springs.
• Raise and lower the door to see if there is any binding or sticking, 20 kgf is the absolute maximum allowable force to raise or lower the door in any position. If your door binds, sticks, or is out of balance, call a trained door technician.

DOOR TYPES

A. Sectional Door with curved track To suit spring balanced Residential Sectional doors up to 13.0 m=. Electrical Connection

ASSEMBLY SECTION

ASSEMBLING THE 3 PIECE SEGMENTED RAIL

The segmented rail is largely preassembled and consists of 3 parts. The carriage, push rod, release handle, the guide pulley and the lintel bracket with chain tensioner are in the front part (A). The seating for the drive shaft and the sprocket are in the rear part (B). Hardware items are placed in the rails during transportation – remove these. Lay the front and rear rail sections one behind the other.

1. Remove cable ties that secure chain. Leave the transport lock (X) still in position.
2. Pull apart the two rail sections completely in order to create a gap for the middle section (C). This rail is designed in such a way so as to easily add the middle section. Slide the 2 connecting pieces (D) over the seams of the rail sections up to the markings. To secure the connecting pieces, bend the sheet metal lugs outwards with a suitable tool. The assembly of the rail is complete.

TIGHTEN THE CHAIN
Note: The spring must be able to compress and bounce during operation. Final tensioning can be performed after installation if necessary. Over tightening the chain may overload the system and cause excessive wear.

1. Tension the chain by adjusting the nut (1), on the pulley assembly, clockwise until the spring is engaged.
2. Continue tightening to compress the spring and remove all the slack in the chain. DO NOT OVERTIGHTEN but ensure chain is firm.
3. 37-41 mm as indicated in the diagram is normal.

FASTEN RAIL TO OPENER

1. Remove transport lock (X). Check if the chain is seated on the gearwheel. If it has slipped off during assembly, relax the spring and tighten again.
2. Position the rail drive spocket (2) over the opener motor shaft (3) and push down to install.
3. Secure the rail on the opener with two C-Rail brackets (4) and the screws (5).
   This completes the assembly of the door opener to the rail.

INSTALLATION SECTION

Wear protective goggles when working overhead to protect your eyes from injury.
Disengage all existing garage door locks to avoid damage to the garage door.
To avoid serious personal injury from entanglement, remove all ropes connected to the garage door before installing the opener.

HEADER BRACKET POSITIONING
The header bracket must be rigidly fastened to a structural support of the garage. Reinforce the wall or ceiling with a 40 mm (1-1/2″) board if necessary. Failure to comply may result in improper operation of safety reverse system.
You can attach the header bracket either to the header wall (1) or to the ceiling (3). Follow the instructions which will work best for your particular requirements.
With the door closed, mark the vertical centre line (2) of the garage door. Extend line onto header wall above the door.
Open door to highest point of travel. Draw an intersecting horizontal line (4) on header wall at least 50 mm above high point to provide travel clearance for top edge of door.

INSTALL THE HEADER BRACKET
NOTE: Refer to vertical centre and horizontal lines created in the previous section for proper placement of header bracket.
A. Wall mount: centre the header bracket (1) on the vertical centre line (2) with the bottom edge of the header bracket on the horizontal line (4) (with the arrow pointing toward the ceiling). Mark all of the header bracket holes (5). Drill 4.5 mm (3/16″) pilot holes and fasten the header bracket with wood screws (3).
B. Ceiling mount: extend vertical centre line (2) onto the ceiling.
Centre the header bracket (1) on the vertical mark no more than 150 mm (6″) from the wall. Make sure the arrow is pointing toward the opener. Mark all of the header bracket holes (5). Drill 4.5 mm (3/16″) pilot holes and fasten the header bracket with wood screws (3). For concrete ceiling mount, use concrete anchors provided.

EAWACH RAIL TO HEADER BRACKET
Attach the Rail to the Header Bracket

• Position the assembled opener on the garage floor below the header bracket. Use foam packing material as a protective base.
  NOTE: If the door spring is in the way you’ll need help.
  Have someone hold the opener securely on a temporary support to allow the rail to clear the spring.

• Position the rail bracket against the header bracket.

• Align the bracket holes and secure with the 80 mm trusshead screw and locknut (1) and (2).

POSITION THE OPENER
Disengage the trolley mechanism (see section “Operating the manual release”) and slide it back towards the powerhead.
Secure the hanging push arm up into the rail assembly temporarily using tape or rope, to avoid a hazard.
SECTIONAL DOOR
You will need a 50 mm piece of timber or similar spacer to gauge the distance between door and rail.

1. Raise the opener onto support.
2. 0pen the door completely, place a 50 mm spacer between the door and the rail (as shown).
3. The final positioning of the rail should be relatively parallel to the horizontal door panels.

EHANG THE OPENER
The opener must be securely fastened to a sound structural support above the opener.

1. Postion the opener as in the previous step. Check the rail is centred over the door (fig. A).
2. The mounting bracket must be mounted so far back that the carriage is not obstructed. The carriage can not pass through the bracket. Mounting at the very back (fig. B) is ideal.
3. Bend ceiling fixtures (1) in such a way that they lie flat against the ceiling. Depending on how large the distance to the ceiling is, none, one or two of the support brackets are to be mounted (fig C1, C2 and C3).
4. Secure the hanging brackets to the ceiling using appropriate screws.
5. Place mounting bracket (2) around the rail, then align to the ceiling fixture and bolt them together.
6. Centre Rail Support Brackets (kit contents item 12) can be installed along the centre of the rail if required. This will reduce flex in the rail that may occur with segmented rails or rail extensions.
7. Check the opener is securely centred over the door.
   Remove the 50 mm spacer, and any other assembly tools. Operate the door manually and check for unrestricted operation.

FASTEN DOOR BRACKET
The door bracket must be securely fastened to the frame or a structural support on the door.
Mounting position for Sectional Doors

1. Align the bracket on the centre line, measure down 100 mm from the door top edge.
2. Secure the bracket in this position on a structural support of the door, using the most suitable variation of holes available.

ATTACH DOOR ARM TO TROLLEY
Make sure the garage door is fully closed. Pull the manual release cord to disengage the trolley. Slide the trolley to around 300 mm from the header bracket.

1. The straight door arm is already preassembled to the trolley.
2. Install the curved arm onto the door bracket using the Clevis pin (2) and R-Clip (3) supplied.
3. Move the straight and curved arms together and secure using two bolts and nuts provided (4). Ensure the angle of the straight arm is around 20 degrees from vertical, when the door is fully closed.

OPERATING THE MANUAL RELEASE

DO NOT DISENGAGE THE OPENER TO MANUAL OPERATION WITH CHILDREN , PERSONS OR OTHER OBJECTS INCLUDING MOTOR VEHICLES WITHIN THE DOORWAY : (The door is under significant tension and if the door has developed a fault or incorrect tension, it may be unsafe and may fall rapidly.)

Without a properly installed safety reversal A system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing door.

• Incorrect adjustment of garage door travel limits will interfere with proper operation of safety reversal system.
• NEVER use force adjustments to compensate for a binding or sticking garage door.
• After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 40 mm high object laid flat on floor.

CAUTION
To prevent damage to vehicles, be sure fully open door provides adequate clearance.

TEST THE SAFETY REVERSE SYSTEM

The safety reverse system test is important. Garage door must reverse on contact with a 40 mm obstacle A laid flat on the floor. Failure to properly adjust opener may result in serious personal injury from a closing garage door. Repeat test once a month and adjust as needed.
Procedure: With door opened place a 40 mm obstacle (1) laid flat on the floor under the garage door. Operate the door in the down direction. The door must reverse off the obstacle. If the door stops on the obstacle, remove obstacle and repeat Program the Limits and Force Steps, then repeat safety reverse test.
When the door reverses off the 40 mm obstacle, remove the obstacle and run the opener through a complete travel cycle. Door must not reverse in closed position. If it does, repeat Program the Limits and Force then repeat safety reverse test.

INSTALL THE PROTECTOR SYSTEM™ (OPTIONAL)

NOTE: This accessory must be used for all installations where the closing force as measured on the bottom of the door is over 400 N (40 kgf).
SPECIAL NOTE: Merlin strongly recommends that The Protector System™ be installed on all garage door openers.
IR BEAMS: By installing IR Beams, an open door is prevented from closing if a person or object is located in the beam area. If the door is already closing, it will return to the open position. A closed door is not prevented from opening.
If the Protector System™is installed and needs to be removed, the opener will need to be reprogrammed (refer to paragraph 4 of the troubleshooting section).
NOTE: A complete set of installation and setup instructions are supplied with the accessory item.
Figures 1, 2 and 3 show recommended assembly of bracket(s) and “C” wrap based on the wall installation of the sensors on each side of the door shown above, or on the door tracks themselves. Figure 4 shows variations which may fit your installation requirements better. Make sure the wraps and brackets are aligned so the sensors will face each other across the door.

• Connect each assembly to a slotted bracket, using the hardware shown. Note alignment of brackets for left and right sides of the door. Finger tighten the lock nuts.

• Use bracket mounting holes as a template to locate and drill two (4.8 mm) diameter pilot holes on both sides of the door so that the beam mounting height is no greater than 100 mm above the floor.

• Attach bracket assemblies with carriage bolts as shown.

• Adjust right and left side bracket assemblies to the same distance out from mounting surface. Make sure all door hardware obstructions are cleared. Tighten the lock nuts.

• Centre each sensor unit in a “C” wrap with lenses pointing toward each other across the door.

• Secure sensors with the hardware provided. Finger tighten the wing nut on the receiving eye to allow for final adjustment.
  Securely tighten the sending eye wing nut.

• Run wires from both sensors to the opener and connect the two white only wires to terminal (2) and the black/white wires to terminal (3) on your opener.

To prevent entrapment, install The Protector System™ no higher than 100 mm above the floor.

TROUBLE SHOOTING

1. Opener doesn’t operate from either door control or remote:
   • Does the opener have electric power? Plug lamp into outlet. If it doesn’t light, check the fuse box or the circuit breaker. (Some outlets are controlled by a wall switch.)
   • Have you disengaged all door locks? Review installation instruction warnings on page 1.
   • Is there a build-up of ice or snow under door? The door may be frozen to ground. Remove any obstruction.
   • The garage door spring may be broken. Have it replaced.

2. Door operates from door control but not from remote:
   • Replace batteries in the remote if necessary.
   • If you have two or more remotes and only one operates, review Program Your Opener, Remote and Keyless Entry.

3. Remote has short range:
   • Check the battery in the remote is fully charged.
   • Change the location of the remote control in the car.
   • A metal garage door, foil-backed insulation or metal siding will reduce the transmission range.

4. Door reverses for no apparent reason and opener light flashes 10 times:
   • Check The Protector System™ (if you have installed this accessory). If the light is flashing, correct alignment.
   If the Protector System™is installed and needs to be removed, the Opener will need to be reprogrammed as follows:
   • Remove the IR Beam wiring from the Opener
   • Turn the power OFF for 5 seconds
   • Turn the power ON for 5 seconds
   • Again turn the power OFF for 5 seconds
   • Turn the power back on and test the opener for normal operation.

5. The garage door opens and closes by itself:
