Pre-Installation
IMPORTANT!
Before
starting
the
installation
read
these
instructions
thoroughly
to
familiarize
yourself
with
all
aspects
of
installation
and
adjustment.
WARNING
IMPORTANT:
IF YOUR GARAGE HAS NO SERVICE ENTRANCE DOOR, INSTALL AN OPTIONAL OUTSIDE QUICK RELEASE LOCK.
THIS ACCESSORY ALLOWS MANUAL OPERATION OF GARAGE DOOR FROM OUTSIDE IN CASE OF POWER FAILURE.
IDENTIFY YOUR DOOR
Identify your door by referring to illustrations below and verify that your door type is a sectional door with curved track.
Do not install if the door is any type of one piece door.
NOTE
: The opener has been designed for sectional doors. Do not attempt to install this opener on any style one piece door.
Using this opener on a one-piece door may result in serious personal injury or property damage.
TEST
YOUR DOOR
Door Test One
Raise and lower the door and check closely for
any sticking or binding that may occur. Lift the
door approximately half way open, as illustrated.
When releasing the door, it should stay in
position. If spring tension pulls the door further
open or door weight pulls it down, your door is
not properly adjusted.
Door Test Two
When properly installed, a door should remain
clear of the opening, when allowed to rest at
its natural, full open position. If “door drift”
pulls door back into opening or spring tension
is not sufficient to pull door totally clear of the
opening, the door is not properly adjusted.
CAUTION:
KEEP CLEAR OF ALL ROTATING AND MOVING PARTS.
FAILURE TO KEEP CLEAR OF ROTATING AND MOVING PARTS CAN RESULT IN SEVERE INJURY.
Before you begin, complete the following two tests to ensure that the door is balanced and working
properly. A door that binds, sticks or is out of balance could cause severe injury. Do not attempt to
compensate for an improperly adjusted door by the installation of an opener. This will interfere with
the proper operation of the opener’s safety features and/or may damage the door or opener. Have a
qualified service person make any needed adjustments or repairs before proceeding with installation.
