The Protector System 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.
Disengage all existing garage door locks to avoid
damage to garage door.
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 Label adjacent to the
wall control 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.
Disconnect electric power to the garage door
opener before making repairs or removing covers.

repaired. Garage doors, door springs, brackets and
their hardware are under extreme tension and can

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.

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.
Take care when operating the manual release as an
open door may fall rapidly due to weak or broken
springs, or being out of balance.
