OPENER
INSTALLATION FOR TRACKLESS DOOR:
Doors that are one piece without tracks are either pivot or jamb
hardware style doors. The principle of installing the guide rail
clear of the door is the same. The major difference is that the
opener unit and track are probably sloped upward toward the door.
- Assemble
the opener unit, track, chain and cable as in "Assembling the
Opener" described earlier.
- Find
the center of the door and place a pencil mark on both the door
and header.
- Open
the door to the highest point of travel and perform the following
calculations: (Height at Highest Point) - (Door Height) = Door
Rise
1. If the rise equals 4" to 8" then locate header bracket 10"
to 15" above the top edge of the closed garage door.
2. If the rise equals 8 to 12", then locate header bracket 15
to 20" above the top edge of the closed garage door.
- Use
a level to draw a line through the center line on the header at
the height above the door determined in Step 3.
- Drill
holes and fasten the header bracket into the header with the hardware
specified in the owner's manual. Have someone assist you in lifting
the pulley end of the guide rail and fasten it to the header bracket.
Leave the opener unit on the floor or slightly elevated during
this step.
- Raise
the opener unit onto a support platform, such as a stepladder
allowing at least 1" clearance from the highest point of the door
travel to the guide rail. The door itself should not be allowed
to swing downhill or past level (horizontal). Adjust the height
to prevent this and/or use stops on the header to prevent this.
- Assemble
the curved arm to the straight release lever attached to the carriage.
- With
the door closed, attach the door bracket to the top of the door
itself. Add an additional piece of wood if needed, or you can
attach it as with a tracked door if the top mounting will not
work.
- With
the door still closed, attach the inner slide to the first link
of the chain before the cable.
COMPLETING
INSTALLATION:
Locate the opener wall switch high enough to prevent children from
playing with the door. Also choose an area that is clear from someone
brushing against it, accidentally causing the door to open or close.
Mount the button with the screws provided. Try to find a wood backing,
such as on a stud or use drywall anchors in wallboard to secure
the button.
Strip
1/2" insulation from the end of the wires and attach them to the
terminals on the button. Mount the operating instructions and provide
warnings on the wall near the push button.
- With
the door open and the carriage disconnected, measure the distance
from the center of the carriage to the "up" actuator.
- Close
the door by hand. Fasten a limit clip on the chain the same distance
from the inner slide that you measured from the carriage to the
"up" actuator, when the door was opened.
- Attach
a third clip to the chain two rollers away from the first "up"
clip. Place this clip toward the inner slide. This clip is called
the safety clip.
You can
adjust the limit clips or adjust the door with the control knobs
on the opener unit, both "up" and "down" by the following test.
- Attach
the carriage to the inner slide or the chain. It is assumed that
the opener unit is plugged into a powered and grounded outlet.
- Press
the wall button to open/close the door. If the clip does not stop
the door at the proper location, move the clip(s). If your opener
does not use clips, make the adjustment at the control knob on
the opener housing.
Push
the button again after any adjustments or to check the opposite
action. Move the clips if they do not allow the door to properly
open or close. Or, use the control knobs on the housing provided.
Moving an "up" clip also required moving the safety clips.
The safety
reverse adjustment is done by testing the pressure that the door
exerts on someone caught in the door closing. Stand clear from the
door and let the closing door push against your hands.
If the
pressure is too great, make the adjustment at the opener unit as
per your owner's manual instructions. Or, adjust the safety beam
location, whichever safety mechanism is used.
Set the
transmitter codes according to the owner's manual instructions.
Locate the transmitter in an accessible position in your car(s),
such as on the sun visor. Most transmitters come with a visor clip.
Replace
the batteries each year or as specified by your owner's manual.
You can usually get replacement transmitters quite easily in case
they are lost or stolen. Always change the code settings when replacing
a transmitter.
