IMPORTANT INSTALLATION INSTRUCTIONS

Congratulations on your purchase of Skylink Garage Door Opener, IQ series, a garage door
opener with many innovative features. Features include extremely quiet operation with DC
motor; automatic force adjustment so the door can be closed with just the right amount of
force, not overpowered; state of the art safety reversal systems that protect your family and
property near the door.
This documentation provided with your opener has been carefully designed and organized to
make the assembly, operation and continued maintenance of your product as easy and safe
as possible, provided it is installed, operated, maintained and tested in strict accordance with
the instructions and warnings contained in this manual. Read and follow all guidelines and
operating instructions before the first use of this product. Store the manual in a safe, easily
accessible location.
Check the following items before assembling the opener:
·Identify the door type, 1) Sectional Door or 2) One-piece Door
·Ensure your garage door is balanced and is not sticking or binding.
·Here is how to check the door balance:
· From outside the garage, slowly open the door all the way and close it all the way,
DOOR SHOULD NOT BIND OR RUB;
· Raise the door halfway up, DOOR SHOULD STAY IN PLACE, SUPPORTED
ENTIRELYBY ITS SPRING
·IMPORTANT: IF THE GARAGE DOOR FAILS EITHER OFTHESE TESTS, HAVE A
QUALIFIED GARAGE DOOR PROFESSIONALADJUST OR REPAIR THE DOOR
·If door is lightweight (made with frame and skin not solid), door (including door frame)
must be braced or reinforced before installing the opener. Check with the garage door
manufacturer or a qualified garage door service professional for a door reinforcement kit.
·If you do not have an access door in addition to the garage door, you should install an
emergency key release kit
·If your door is more than 7 feet high, you will need a rail extension kit (purchased
separately).
·With the garage door closed, check alignment of door and garage floor. The gap, if any,
should be no more than ¼”. If the gap is larger than this, repair floor or door before
installing opener.

1. READANDFOLLOWALLINSTALLATION
INSTRUCTIONS.
2. Check with the door manufacturer to determine
if additional reinforcement is required to support
the door prior to installation of the garage door
opener.
3. Install garage door opener only on a properly
balanced garage door. An improperly balanced
door could cause serious injury. Have a qualified
service person make repairs to garage door
cables, spring assemblies, and other hardware
before installing the opener.
4. Remove all ropes and disable all locks connected
to the garage door before installing opener.
5. If possible, install the door opener 7 feet or more
above the floor. Mount the emergency release
handle 6 feet above floor.
6. Do not connect the opener to source of power
until this manual instructs you to do so.
7. Locate the wall console or wall button:
I. Within sight of the garage door
II. Out of reach of children at minimum height of
5 feet
III.Away from all moving parts of the door
8. Place Entrapment Warning Label on wall next
to garage door wall control
9. Place manual release / safety reverse test label
in plain view on inside of garage door.
10.Upon completion of the installation, the door
must reverse when it comes in contact with a
1-1/2" high object (or a 2 X 4 laid flat at the
center of the door) on the floor and when the
infrared safety beam is blocked.

Hanging brackets should be angled to provide
rigid support. Measure the distance from the
motor unit to the structural support. Cut and
bend the hanging brackets as required.
For “Open-Seam” garage, attach the hanging
brackets directly to joists with two lag screws. On finished ceiling, attach a sturdy metal bracket (not provided) to

Important Information: The safety beam sensor can detect obstacle in the
path of its invisible beam. When the beam is obstructed while the door is
closing, the door will stop immediately and reverse to the fully open position,
and the opener lights will flash. It is important to ensure the invisible infrared
beam must be unobstructed by any part of the garage door, door tracks,
other hardware or objects near the garage door.
The unit has red LED is the transmitting
sensor. The unit has green LED is the
receiving sensor. Avoid sun light shinning
directly into the receiving sensor.
Note: Receiving sensor has
a label marking “Receive”
on the wire.
Follow the same procedure to
install the sensor on the other
track. Ensure they are on the
same level facing each other.

Loosen the wing nut on
the mounting bracket.
Slide the mounting bracket

Ensure the sensor is no

wing nut so the safety
beam sensor is secure on
the door track.

If the receiver LED is off,

not obstructed), alignment
is required.
Loosen the wing nut on the transmitting sensor (with
RED LED on) and adjust the angle so it points toward
the receiving unit.
If the green LED on the receiving unit is on steadily, your
safety sensors are aligned properly. If the green LED is
flashing or off, loosen the wing nut on the receiving unit,
adjust the angle until the green LED is on steadily, then
tighten the wing nut.

Note:
Be sure to stay out of the beam’s path while aligning

Note:
If the transmitting sensor LED does not glow steadily, check the following:
I. Power to the Opener is connected
II. A short in the white or white/red wires (from wire holders or at the openers terminals)
III. Incorrect wiring between sensors and opener
IV.A broken wire
If the transmitting sensor LED glows steadily but the receiving sensor LED doesn’t glow:
I. Check alignment
II. Check for an open wire to the receiving sensor
III. Check for dirt on lens, or sun shinning into lens
