Chamberlain LiftMaster Professional LM800A Manuel D'instructions page 11

Failure to comply with the following instructions may result in serious personal injury or property damage.
• Read these instructions carefully
• The garage door opener is designed and tested to offer reasonable safe service provided it is installed and operated in strict
accordance with the instructions in this manual.
These safety alert symbols mean Warning – a personal safety or property damage instruction. Read these instructions carefully.
Warning: If your garage has no service entrance door, Model 1702E 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 or binding doors must be repaired. Garage doors,
door springs, cables, pulleys, brackets and their hardware
are under extreme tension and can cause serious personal
injury.
Do not attempt to loose, move or adjust them. Call for
garage door service.
Do not wear rings, watches or loose clothing while
installing or servicing a garage door opener.
To avoid serious personal injury from entanglement,
remove all ropes connected to the garage door before
installing the door opener.
Installation and wiring must be in compliance with your
local building and electrical codes. Connect the power
supply cord only to properly earthed mains.
Lightweight doors of fiberglass, aluminum or steel
must be substantially reinforced to avoid door damage.
(See page 6.) The best solution is to check with your
garage door manufacturer for an opener installation rein-
forcement kit.
The safety reverse system test is very important. Your
garage door MUST reverse on contact with a 40mm obsta-
cle placed on the floor. Failure to properly adjust the open-
er may result in serious personal injury from a closing
garage door. Repeat the test once a month and make
any needed adjustments.
This unit should not be installed in a damp or wet
space.
Door must not extend over public byway during opera-
tion.

BEFORE YOU BEGIN:
1. Look at the wall or ceiling above the garage door. The header bracket must be securely fastened to structural supports.
2. Do you have a finished ceiling in your garage? If so, a support bracket and additional fastening hardware (not supplied) may be required.
3. Depending on your door's construction, you might need a special door arm. See your dealer.
4. Do you have an access door in addition to the garage door? If not, Model 1702E Outside Quick Release Accessory is required. This accessory
allows manual operation of the garage door from outside in case of power failure.

The Protector System must be installed when the
force at the edge of the closing door force exceeds
400N (40kg). Excessive force will interfere with the proper
operation of the Safety Reverse System or damage the
garage door.
Permanently fasten the caution label adjacent to the wall-
mounted door control control button as a reminder of safe
operating procedures.
Disengage all existing garage door locks to avoid dam-
age to garage door.
Install the lighted door control button (or any additional
push buttons) in a location where the garage door is
visible, at a height of at least 1.5m and out of the
reach of children. Do not allow children to operate
push button(s) or remote control(s). Serious personal
injury from a closing garage door may result from misuse
of the opener.
Activate opener only when the door is in full view, free
of obstructions and 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.
Use manual release only to disengage the trolley and, if
possible, only when the door is closed. Do not use the
red handle to pull the door open or closed.
Disconnect electric power to the garage door opener
before making repairs or removing covers.
This product is provided with a power supply cord of spe-
cial design which, if damaged, must be replaced by a
power supply cord of the same type; such a power sup-
ply cord may be obtained and fitted by a specialist.
