Install The Door Control - Chamberlain PD752CDS 3/4 HP Owner's Manual

INSTALLATION STEP 6

Install the Door Control

Locate door control within sight of door at a minimum
height of 5 feet (1.5 m) where small children cannot
reach, and away from moving parts of door and door
hardware. The installation surface must be smooth and
fl at. 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 or amber 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 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 WHT and
white/red wire to the RED (Figure 3).
2. Remove cover by gently prying on a side corner near
the top of the cover with a small fl at head screwdriver
(Figure 4). Fasten with 6ABx1-1/4" self-tapping screws
(drywall installation) or 6-32x1" machine screws
(into gang box) as follows:
• Drill and 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 fi t.
• Install top screw with care to avoid cracking plastic
housing. DO NOT overtighten.
• Insert bottom tabs and snap on cover.
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. Strip 7/16" (11 mm) of insulation from end of bell wire.
Connect bell wire to the quick-connect terminals as
follows: white to white and white/red to red (Figure 5).
NOTE: When connecting multiple door controls to the
opener, twist same color wires together. Insert wires
into quick-connect holes: white to white and red/white
to red.
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 power and operate 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.
To prevent possible SERIOUS INJURY or DEATH from
electrocution:
• Be sure power is NOT connected BEFORE installing
door control.
• Connect ONLY to 24 VOLT low voltage wires.
To prevent possible SERIOUS INJURY or DEATH from a
closing garage door:
• Install door control within sight of garage door, out
of reach of children at a minimum height of 5 feet
(1.5 m), and away from ALL moving parts of door.
• NEVER permit children to operate or play with door
control push buttons or remote control transmitters.
• Activate door ONLY when it can be seen clearly, is
properly adjusted, and there are no obstructions to
door travel.
• ALWAYS keep garage door in sight until completely
closed. NEVER permit anyone to cross path of
closing garage door.
