WARNING!

START BY READING THESE IMPORTANT SAFETY INSTRUCTIONS

•Failuretocomplywiththefollowinginstructions mayresultinseriouspersonalinjuryorproperty damage.

• Read and follow all instructions carefully.

• The garage door opener is designed and tested to offer safe service, provided it is installed and operated in
strict accordance with the instructions in this manual.

These safety alert symbols mean WARNING : A possible risk to personal safety or property
damage exists.

Keep garage door balanced. Do not let the garage door
opener compensate for a binding or sticking garage door.
Sticking, binding or unbalanced doors must be repaired

efore installing this opener.

b
Do not wear rings, watches or loose clothing while

installing or servicing a garage door opener. Wear gloves,
safety goggles and suitable protective clothing where
appropriate.

Frequently examine the door installation, in particular
cable, springs and mountings for signs of wear, damage or
imbalance. Do not use if repair or adjustment is needed
since springs and hardware are under extreme tension
and a fault can cause serious personal injury.

To avoid serious personal injury from entanglement,

remove all ropes, chains and locks connected to the
garage door before installing the door opener.

Installation and wiring must be in compliance with your

local building and electrical codes.
The safety reverse system test is very important. Your

garage door MUST reverse on contact with a 40 mm
obstacle placed on the floor. Failure to properly adjust the
opener may result in serious personal injury from a closing
garage door. Repeat the test once a month and make

any necessary adjustments.

This appliance is not intended for use by persons
(including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction
concerning use of the appliance by a person responsible
for their safety.

Use the Manual Release only for the seperation of the
carriage from the drive and - if possible - ONLY with the
door closed. Do not use the red handle to push the door
up or pull it down. Operation of the emergency release can
lead to uncontrolled movements of the door, if springs are
weak or broken or if the door is unbalanced. Mount the
release handle of the emergency release at a height less
than 1.8 m from the floor.

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

be installed on all garage door openers.

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.)

. Do you have a finished ceiling in your garage? If so, a support bracket and additional fastening hardware (not supplied) may

2

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

ASSEMBLING THE 3 PIECE SEGMENTED RAIL

8

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.

. 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

2
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

9

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

10

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.

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

12

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.

be installed on all garage door

openers.

R BEAMS: By installing IR Beams, an open door is prevented

I

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.

TM

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
