The Protector System

TM

must be used for

all installations where the closing force
as measured on the bottom of the door is
over 400N (40kgf). 
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 1.5m and out of the reach of
children. The appliance is not intended
for use by young children or infirm
persons without supervision. 
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.

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

KEEP THESE INSTRUCTIONS

WARNING

• Failure to comply with the following instructions may result in serious personal injury or property 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.

NOTE: If your garage has no service entrance door, a CM1702 outside quick release must be installed.
This accessory allows manual operation of the garage door from outside in case of power failure.

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 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 40mm 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 opener should not be installed in a
damp or wet space exposed to weather.

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