The opener must not be used on a wicket
door (door within a door).

The Protector SystemTMmust be used for all
installations where the closing force as
measured on the bottom of the door is over
400 N (40 kgf). Excessive force will interfere

with the proper operation of the safety reverse
system or damage the garage door.

After installation, ensure that the parts of
the door do not extend over public
footpaths or roads.

Install the wireless wall control (or any
additional wall control) in a location where

the garage door is visible, at a height of at
least 1.5 m and out of the reach of children.
Do not allow children to operate push
button(s) or transmitter(s). Serious personal

injury from a closing garage door may result
from misuse of the opener.

Permanently fasten the Warning Labels in
prominent places, adjacent to wall controls

and manual release mechanisms as a
reminder of safe operating procedures.

Activate opener only when the door is in
full view, free of obstructions and the
opener is properly adjusted. No one should
enter or leave the garage while the door is
in motion.

Do not allow children to play near the door,
or door controls.

If the supply cord is damaged, it must be replaced
by the manufacturer, its service agent or similarly
qualified persons in order to avoid hazard.

Disconnect electric power and battery to
the garage door opener before making
repairs or removing covers.

• 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.

T

hese safety alert symbols mean WARNING : A possible risk to personal safety or

property damage exists.

NOTE: If your garage has no service entrance door, a CM1702 outside quick release must be installed.

garage door opener compensate for a binding or
sticking garage door. Sticking, binding or
unbalanced doors must be repaired before
installing this opener.

Do not wear rings, watches or loose clothing

while installing or servicing a garage door opener.
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 capablities, 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

drum is on the edge of the curtain or is a smaller diameter, additional clearance may be required.

If the drum is more than 60 mm from the curtain edge or of a smaller diameter, an extension pole kit
may be required.

Different drum and bracket types may result in the minimum side room clearance not being possible and
extension poles being required. Ensure there is a power point near the opener.

ESTING THE DOOR

4

Complete the following test to ensure your door is well
balanced, and not sticking or binding:

• Disable all locks and remove any ropes connected to the
garage door.

•

Lift the door to about halfway and then release it. The
door should remain spring balanced.

• Raise and lower the door to determine if there are any
sticking or binding points (20 kgf is the absolute maximum
allowable to raise or lower the door in any position).

• If your door does not hold in place or the door binds or
sticks, call a qualified door technician before installing the
opener.

Non opener side

Opener side

• Install the stop collar on the opposite end to where
the opener is to be installed.

• Fit the stop collar hard against the boss of the door
drum. Ensure the U-bolt holding the door shaft to the door
bracket is tightly secured.

INSTALLING THE STOP COLLAR

5

• Place the weight in the centre of the door (as shown).

• Use a pencil to mark the two hole positions.

• If the door curtain does not have a handle you will need
to drill two 5.5 mm holes through the two marked

positions, then place the weight bar on the inside of the
door.

• Use the bolts, washers and nuts (provided) to

fasten the weight bar in place.

NOTE: If the door has a lifting handle, remove the
handle, nuts & bolts. Place weight bar over the
handle holes, insert extended bolts through the
weight bar & fasten handle back in place.

SAFETY CHECK!

Is the stop collar

installed?

YES: proceed to the next

step

NO: install the stop collar

before proceeding

PINNING THE DOOR

Note: A ballooning door may delay the safety reversal
response and can compromise garage door security.

• To remedy any ballooning place self tapping metal screws
or rivets where the curtain leaves the roll. Secure these
through the curtain into the drum wheel at each end of the
roll.

• After determining the correct fastener location as shown, lift
the door approximately half a turn from the closed position
to allow access for drilling.

THE RELEASE HANDLE & CORD

• Thread one end of the rope through the hole in the top
of the red release handle so that “NOTICE” reads
right side up as shown.

• Secure with an overhand knot at least 25 mm from the

e

nd of the rope to prevent slipping.

• Thread the other end of the rope through the loop of

the manual release cable.

•

Adjust rope length so the handle (when installed) will
be no higher than 1.8 m above the floor. Secure with

an overhand knot. If the door is greater than 2.5 m in
height the release cord extension kit accessory is
required.

NOTE: Final adjustment of handle height should be
completed after the opener is installed. If it is
necessary to cut the rope, heat seal the cut end to
prevent unravelling (refer section 16).
