IMPORTANT! PLEASE READ THESE INSTRUCTIONS CAREFULLY PRIOR TO
INSTALLATION OF THE ROLLER DOOR MOTOR.
This automatic opener has been designed to provide years of trouble free use. The opener will
perform efficiently only if it is installed and operated correctly.
READ THESE IMPORTANT SAFETY RULES FIRST.
Keep garage door balanced. Sticking or binding doors must be repaired. Garage doors, door
springs, brackets and their hardware are under extreme tension and can cause serious personal
injury. Do not attempt adjustment. Call professional garage door installers.
Do not wear rings, watches or loose clothing while installing or servicing a garage door operator.
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 a contact
with a
5 to 10cm high object on the floor. Failure to properly adjust the operator may result in serious
personal injury from a closing garage door. Repeat the test once a month and make any needed
adjustments. (See Sensitivity adjustment).
ET-12A operator has an electronic obstruction system that provides safe and reliable operation.
It is however a legal requirement in some countries to also install a Photo-electric sensor across
the door way. Please check this requirement with your local distributor.
Do not use the force adjustments to compensate for binding or sticking garage doors. Excessive
force will interfere with the proper operation of the Safety Reverse System or damage the garage
door.
This unit should not be installed in a damp or wet space.
Disengage all existing garage door locks to avoid damage to garage door.
Install the lighted door Control Box (or any additional Push Buttons) in a location where the
garage door is visible, but 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 operator.
CAUTION: Activate operator only when the door is in full view, free of obstructions and operator
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 operator before making repairs or removing covers.
IMPORTANT: Label a caution mark to the rear of the garage door as a reminder of safe
operating procedures.

Pre-installation Notes
Right hand installation shown (inside garage looking out)Fig1
Check that there is sufficient side clearance to fit the operator unit. It may be fitted to either
the right or left hand side.
(1) Minimum side clearance:
The minimum side clearance between door
curtain and the inside edge of mounting
bracket is 85mm; The minimum side
clearance between door curtain and the
outside edge of mounting bracket is 135mm.
(2) Recommended side clearance The
recommended side clearance between door
curtain and the inside edge of mounting bracket
is 110mm;
The recommended side clearance
between door curtain and the outside
edge of mounting bracket is 160mm.
If the operator is being fitted at the same time as the new door installation, read these
instructions in conjunction with the roller door installation instructions.
If the operator is being retro-fitted, make sure the door operates smoothly and is properly
balanced.
N.B.: SPECIAL CARE SHOULD BE TAKEN IF RE-TENSIONING OF THE DOOR IS
REQUIRED.
At no stage should you loosen both “U” bolts if door is under tension.
