Planning

Survey your garage area to see if any of the conditions below apply to your installation. Additional materials may be required. You may find it helpful to refer back to this page as you proceed with the installation of your opener.
Depending on your requirements, there are several installation steps which may call for materials or hardware not included in the carton.
This opener is compatible with:
• Doors that use a torsion bar, springs and a door no more than 14' (4.2 m) high.
• 4"-6" (10 cm - 15 cm) drums, not to be used on tapered drums over 6" (15 cm).
• High lift and standard lift sectional doors up to 14' (4.2 m) high.
• Doors up to 18' (5.4 m) wide.
• Doors up to 180 sq. ft. (16.7 sq. m).
• 1" (2.5 cm) torsion bar only.
• Review or inspect proposed installation area. Opener can be installed on left or right side of door. Select the side that meets the requirements listed below.
- Must have minimum of 2-1/2" (6.4 cm) between the garage wall and the center of the torsion bar.
- Must have minimum of 3" (7.6 cm) between the ceiling and the center of torsion bar.
- Must have minimum of 8" (20.3 cm) between the side garage wall (or obstruction) and the end of torsion bar.
• The torsion bar must extend at least 1" to 5" (2.5 cm to 12 cm) past the bearing plate.
• An electric outlet is required within 6' (1.8 m) of the installation area. If outlet does not exist, contact a qualified electrician.
• Depending upon garage construction, extension brackets or wood blocks may be needed to install safety reversing sensors.
• Alternate floor mounting of the safety reversing sensors will require hardware not provided.
• A model 475LM EverChargeTMBattery Backup System is strongly recommended if there is no access door to the garage, as this opener cannot be used in conjunction with an external emergency release mechanism.
• Any gap between the floor and the bottom of the door must not exceed 1/4" (6 mm). Otherwise the safety reversal system may not work properly.
NOTE: Inspect the torsion bar while the door is raised and lowered. It is important that there is no noticeable movement up and down or left and right. If this type of movement is not corrected, life of this opener will be greatly reduced.

Preparing your Garage Door

Before you begin:
• Disable locks.
• Remove any ropes connected to garage door.
Complete the following test to make sure your garage
door is balanced and is not sticking or binding:
1. Lift the door about halfway as shown. Release the door. If balanced, it should stay in place, supported entirely by its springs.
2. Raise and lower the door to see if there is any binding or sticking.
If your door binds, sticks or is out of balance, call a trained door systems technician.
3. Verify equal cable tension on each side of door. Cable tension should remain equal during the entire travel of the door.
To prevent damage to garage door and opener:
• ALWAYS disable locks BEFORE installing and operating the opener.
• ONLY operate garage door opener at 120V, 60 Hz to avoid malfunction and damage.
To prevent possible SERIOUS INJURY or DEATH:
• ALWAYS call a trained door systems technician if garage door binds, sticks or is out of balance. An unbalanced garage door may not reverse when required.
• NEVER try to loosen, move or adjust garage door, door springs, cables, pulleys, brackets or their hardware, ALL of which are under EXTREME tension.
• Disable ALL locks and remove ALL ropes connected to garage door BEFORE installing and operating garage door opener to avoid entanglement.

INSTALLATION STEP 5

Install the Door Control

Locate door control within sight of door, at a minimum height of 5' (1.5 m) where small children cannot reach, away from moving parts of door and door hardware. If installing into drywall, drill 5/32" holes and use the anchors provided. For pre-wired installations (as in new home construction), it may be mounted to a single gang box (Figure 1).
NOTE: The functional temperature range of the door control is between -20°C (-4°F) and +50°C (+122°F). Scroll speed of display is slower at lower temperatures although the door control remains fully functional.
CAUTION: Continuous exposure of the door control to temperatures below -22°F (-30°C) may damage the LCD screen.
SPECIAL NOTE: Only one 398LM can be connected to each garage door opener. If additional wall controls are desired to operate the same garage door opener, it is recommended to use model 378LM wireless wall control as the secondary door control.
1. Strip 7/16" (11 mm) of insulation from one end of bell wire and connect to the two screw terminals on back of door control by color: white wire to the W (2) and white/red wire to the R (1) (Figure 2).
2. Remove push bar cover by gently prying at the lower/middle portion of the cover with a small flat-head screwdriver. Fasten with 6AB x 1-1/4" self-tapping screws (drywall installation) or 6-32 x 1" machine screws (into gang box) as follows:
• Install bottom screw, allowing 1/8" (3 mm) to protrude
above wall surface.
• Position bottom of door control on screw head and
slide down to secure. Adjust screw for snug fit.
• Drill and install top screw with care to avoid cracking
plastic housing. Do NOT overtighten.
• Replace cover by inserting top tabs first and then snap
