Start by Reading These Important Safety Instructions
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 1702AML 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.
This is a class 2 double insulated product,
connection to earth is not required or
provided.
Lightweight fiberglass doors, aluminum or
steel must be substantially reinforced to
avoid door damage. (See page 3.) The best
solution is to check with your garage door
manufacturer for an opener installation
reinforcement kit.
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 needed adjustments.
This unit should not be installed in a damp
or wet space.
Door must not extend over public byway
during operation.
