INSTALLATION STEP 6
Install the Door Control
Locate door control within sight of the door at a
minimum height of 5 feet (1.5 m) where small
children cannot reach, and away from moving parts
of the door and door hardware. The installation
surface must be smooth and flat. If installing into
drywall (Figure 1), drill 5/32" holes and use anchors
provided. For pre-wired installations (as in new home
construction), it may be mounted to a single gang
box (Figure 2). NOTE: After installation, a green
indicator light behind the cover will indicate proper
connection. If not lit, the Lock and Light features will
not function (reverse wires to correct).
1. Strip 1/4" (6 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 2 and
white/red wire to 1 (Figure 3).
2. Remove cover by gently prying at slot on the side
of the cover with a small flat head screwdriver
(Figure 4). Fasten with 6ABx1-1/4" self-tapping
screws (standard installation) or 6-32x1" machine
screws (into gang box) as follows:
• Drill and install bottom screw, allowing 1/8" to
protrude above wall surface.
• Position bottom of door control on screw head
and slide down to secure. Adjust for snug fit.
• Install top screw with care to avoid
cracking plastic housing. Do not overtighten.
• Insert bottom tabs and snap on cover.
(To remove cover after mounting, gently pry at
top with paper clip or small flat head screwdriver.)
NOTE: The push bar may stick if the door control is
not mounted on a smooth surface. If a click is not
heard when pressing the push bar, loosen the two
mounting screws or relocate the door control to a
smoother surface.
3. (Standard installation only) Run bell wire up wall
and across ceiling to motor unit. Use insulated
staples to secure wire in several places. Do not
pierce wire with a staple, creating a short or open
circuit.
4. Connect bell wire to the opener terminal screws as
follows: white to 2 and white/red to 1 (Figure 5).
5. Use tacks or staples to permanently attach
entrapment warning label to wall near door control,
and manual release/safety reverse test label in a
prominent location on inside of garage door.
NOTE: DO NOT connect the power and operate the
opener at this time. The trolley will travel to the full
open position but will not return to the close position
until the sensor beam is connected and properly
aligned. See Safety Reversing Sensor Instructions
beginning on page 16.
