IMPORTANT SAFETY INFORMATION
Both the installer and the owner and/or operator of this
system need to read and understand this installation
manual and the safety instructions supplied with other
components of the gate system. This information
should be retained by the owner and/or operator of the
gate.
WARNING! To reduce the risk of injury or death
1. READ AND FOLLOW ALL
INSTRUCTIONS.
2. Never let children operate or play with gate
controls. Keep the remote control away from
children.
3. Always keep people and objects away from
the gate. NO ONE SHOULD CROSS THE
PATH OF THE MOVING GATE.
4. Test the gate operator monthly. The gate
MUST reverse on contact with a rigid object
or stop when an object activates the noncontact sensors. After adjusting the force or
the limit of travel, retest the gate operator.
Failure to adjust and retest the gate operator
properly can increase the risk of injury or
death.
5. Use the emergency release only when the
gate is not moving.
6. KEEP GATES PROPERLY MAINTAINED. Read
the owner’s manual. Have a qualified service
person make repairs to gate hardware.
7. The entrance is for vehicles only. Pedestrians
must use separate entrance.
8. SAVE THESE INSTRUCTIONS.
When installing the photo-beams supplied with this
unit two things need to be considered.
1. Care should be exercised to reduce the risk of
nuisance tripping, such as when a vehicle, trips
the sensor while the gate is in motion.
2. One or more photo-beams shall be located
where the risk of entrapment exists, such as
the perimeter reachable by the moving gate
leaf.
GATE DESIGN
1. A gate is a potential traffic hazard, so it is important that you locate the gate far enough away
from the road to eliminate the potential of traffic
getting backed up. This distance is affected by the
size of the gate, how often it is used, and how fast
the gate operates.
2. The operator you choose to install on your gate
must be designed for the type and size of your
gate and for the frequency with which you use the
operator.
3. Your gate must be properly installed and must work
freely in both directions before the automatic
operator is installed.
4. An automatic operator should be installed on the
inside of the property/fence line. Do not install the
operator on the public side of the property/fence
line.
5. Pedestrians should not use a vehicular gate system.
Prevent such inappropriate use by installing
separate gates for pedestrians.
6. Exposed, reachable pinch points on a gate are
potentially hazardous and must be eliminated or
guarded.
7. Outward swinging gates with automatic operators
should not open into a public area.
8. The operating controls for an automatic gate must
be secured to prevent the unauthorized use of those
controls.
9. The controls for an automatic gate should be
located far enough from the gate so that a user
cannot accidentally touch the gate when operating
the controls.
10. An automatic gate operator should not be installed
on a gate if people can reach or extend their arms
or legs through the gate. Such gates should be
guarded or screened to prevent such access.
INSTALLATION
1. If you have any question about the safety of the
gate operating system, do not install this operator.
Consult the operator manufacturer.
2. The condition of the gate structure itself directly
affects the reliability and safety of the gate
operator.
3. Only qualified personnel should install this
equipment. Failure to meet this requirement could
cause severe injury and/or death, for which the
manufacturer cannot be held responsible.
4. The installer must provide a main power switch that
meets all applicable safety regulations.
5. Clearly indicate on the gate with the 2 warning signs
that are included (visible from either side of the
gate).
6. It is extremely unsafe to compensate for a damaged
gate by increasing hydraulic pressure.
7. Devices such as reversing edges and photobeams
must be installed to provide better protection for
personal property and pedestrians. Install reversing
devices that are appropriate to the gate design and
gate application.
8. Before applying electrical power, be sure that the
voltage requirements of the equipment correspond
to your supply voltage. Refer to the label on your
operator system.

THE 750 OPERATOR
GENERAL CHARACTERISTICS
The FAAC 750 Operator is an automatic gate operator
for a swinging gate leaf. It can accommodate a gate leaf
of up to 1760 lb (800 kg) and up to 13 ft (4 m) in
length.
The 750 Operator is a two piece unit consisting of a
hydraulic power (or pump) unit and a hydraulic ram (or
drive) unit which are connected by the means of two
hydraulic hoses.
The 750 Operator can be used to swing the gate leaf
inward or outward. Some versions provide hydraulic
locking in at least one position, either opened or closed,
depending on how it was ordered.
The hydraulic lock is a service device rather than a
security device. Additional, external locks are
recommended under the following conditions:
• You are installing the Model 750 SB.
• The length of the gate leaf is 7 ft or more.
• The installation requires tight security.
• The site is subject to vandalism.
• The site is subject to strong or very gusty wind.
• You are installing a solid face gate.
For gates with two leaves, two operators are installed,
one on each leaf, and both are wired to one control
panel. In such two-operator gate installations, one leaf
can be programmed to open/ close slightly later than
the other leaf to accommodate overlapping gate
designs.
For its protection, the single-phase, bidirectional motor
shuts off automatically if its operating temperature
reaches 212 deg F (100 deg C). Also for the protection
and proper operation of the 750 Operator, each gate
leaf on which it is installed must have a fixed positive
stop in both the opened and closed positions.
The 750 Operator also includes a key operated Manual
Release mechanism and two bypass valves that precisely
control the force applied to the gate leaf through the
750 Operator.
The Manual Release mechanism is a lever that
disengages (or engages) the hydraulic system of the 750
Operator. When the hydraulic system is disengaged, you
can open and close the gate leaf by hand. Such manual
operation of the gate is necessary during installation
and useful during power failures.
Additional reversing devices (such as inductive loops
and photocells) should be installed to provide more
complete protection for people and property.
The electronic control panel is a microprocessor-based
controller that accepts a wide range of product
accessories and reversing devices, thus allowing for
flexible gate system design.
INSTALLATION INSTRUCTIONS
Note: The following installation instructions assume
you are fully capable of installing a gate operator.
This manual does not instruct you in designing a
gate, installing a gate, or basic electrical wiring. The
installation tasks discussed in this manual are tasks
particular to the 750 Operator
.
PREPARING THE GATE
Before you install the 750 Operator, you must insure
that the gate leaf meets the following criteria.
1. The gate leaf must not exceed the weight and
length constraints for 750 Operator that you
have.
June, 2004
750 Operator And
455 D Control Panel Installation Manual
Page 7
2. The distance between the gate post and the
center of the gate hinge must be at least 2 3/8
in. (6 cm).
3. Make sure the gate leaf has positive stops in
both the opening and closing directions (see
Figure 3).
Note: If you are installing the 750 Operator with an
extension arm, some of the constraints about the
gate leaf may not apply to you. See the section
"Installing an Extension Arm" for more information
on page 14 & 15.
INSTALLING THE 750 OPERATOR
Installing the 750 Operator consists of the
following steps:
• Setting the concrete forms
• Installing the power unit
• Installing the drive unit
• Connecting the hydraulic lines
• Synchronizing the hydraulic system
• Installing the gate leaf shoe
• Installing the gate leaf
• Installing the control panel
• Adjusting the hydraulic pressures for the
operator
• Checking the motor rotation
• Bleeding the hydraulic system
• Adjusting the bypass valves
SET THE CONCRETE FORMS
You need to lay out the concrete forms according to the
dimensions shown in Figures 3 and 4. (Your soil
conditions will also determine the size of the cement
footing.)
Note: If the vertical distance between the finished
grade and the bottom of the gate leaf exceeds 1 1/4
in. (3.3 cm) as shown in Figure 4, you can install a
shear-pin assembly as shown in Figure 8 and as
discussed in “Installing the Gate Leaf Shoe.”
Accurately positioning the foundation plate beneath the
gate hinge is critical especially if it supports the drive
unit, which supports the gate leaf.
Note: The foundation plate may be supplied by the
installer. If so, it must meet the specifications
shown in Figure 3.
Note: Insure that the cavity where the drive unit is
located is well drained by means of pipes, gravel
drainage, or both, whatever is appropriate for your
soil conditions.
After the concrete is poured in the form and before it
has a chance to set, insert the foundation plate into the
cement and position it so that it is flush with the top of
the concrete and is level.
Allow the concrete to set a minimum of two full days
before you install the drive unit on top of it.

INSTALL THE POWER UNIT
Figure 5 shows important dimensions and parts of the
vinyl power unit box.
There are two constraints to installing the power unit
box for the 750 Operator:
1. We recommend that you install the power unit box
so that the hydraulic lines between it and the drive unit
are no longer than 20 ft (6 m).
2. The power unit itself must be installed so that the
vent screw is on the top of the unit as shown in Figure
5.
The power unit box that ships with your operator
hinges on the left, but you can reverse the opening
direction of the door if necessary for your installation.
To reverse the opening direction, open the cover, and
then gently pull it off the box. The vinyl hinges can now
be placed in the hinge receptacles on the right-hand
side. Secure the hinges with the screws provided.
You may surface mount the power unit box to a vertical
surface or you may recess it.
To mount the power unit box use the 3/16-in. holes
provided (relocating the holes in the box will
compromise its integrity).
If you recess the box, keep in mind that hydraulic hoses
and electrical wiring need to enter the bottom of the
box.
Also, recessing must not interfere with the hinge
assembly of the power unit box. You need to keep in
mind the following dimensions.
Height: 14 1/4 in. (36.2 cm)
Width: 10 in. (25.5 cm)
Depth: maximum of 2
At this time, you also need to remove the vent screw
located on the power unit. The vent screw is in the
middle of the top, left side of the power unit as shown
in Figure 5.
Caution: Failure to remove the vent screw in the
power unit may result in erratic operation of the 750
Operator.

INSTALL THE DRIVE UNIT
To install the drive unit, first make sure the four
leveling bolts on the base of the unit do not protrude
from the bottom of the unit. Then place the unit on the
foundation plate (see Figure 6).
Position the drive unit according to the following:
The side of the drive unit with the splined shaft should
be the side nearest the gate post.
The longitudinal axis of the drive unit is perpendicular
to (at right angles to) the fully closed gate leaf.
The center of the splined shaft is vertically aligned with
the center of the gate hinge axis (use a plumb line).
Caution: NEVER weld the base plate of the drive unit
to the foundation plate. Weld only the mounting C
brackets to the foundation plate.
When the position of the drive unit meets these
conditions, weld the C-shaped mounting brackets to the
foundation plate to hold the drive unit in position (see
Figure 6).
Next you need to prepare the two L-shaped "box halves"
for installation. Note that the lip on each piece should
be on top so as to support the top cover. Make the
necessary holes for the two hydraulic lines that run
from the drive unit to the power unit.
Once you have made your access holes, you can weld
the box halves to the foundation plate and to one
another so as to enclose the drive unit on four sides. Be
sure to protect the drive unit during welding.

455 D Control Panel Installation Manual
CONNECT THE HYDRAULIC LINES
Caution: It is important that the hydraulic lines
be kept clean of any debris.
The drive unit and power unit are connected by two
hydraulic lines, each with an outside diameter of 5/16 in.
(0.8 cm), an inside diameter of 5/32 in. (0.4 cm), and a
2,500 psi (170 bar) rating.
Caution: After removing the nylon piping, do not
rotate the splined shaft while you are connecting the
hydraulic lines to avoid squirting hydraulic fluid.
Remove the nylon piping connecting the two hydraulic
pipe fittings on the drive unit. Clean up any spilled
hydraulic fluid.
Be sure the hydraulic lines are free of any debris by
flushing them with a jet of compressed air. Then attach
one line to each fitting on the drive unit.
Next you attach the other end of the hydraulic lines to the
pipe fittings on the power unit (see Figure 7; additional
information can be found in the technical drawing on
page 21. Attaching the correct line to the correct fitting is
important. Make sure that the hose on the end of the
drive unit that is on the closing side of the gate/fence line
attaches to the hydraulic pipe fitting in the power unit
that is nearest the green bypass valve screw. This
connection insures that the green valve controls opening
pressure.
SYNCHRONIZE THE HYDRAULIC SYSTEM
Next you need to disengage the hydraulic system in order
to synchronize it.
Inside the power unit is the Manual Release lever that
disengages the hydraulic system (see Figure 1). Make sure
the Manual Release lever is turned toward you and down
to disengage the hydraulic system.
Now you can synchronize (set) the hydraulic system to the
closed position by turning the splined shaft in the closing
direction. Turn the shaft as far as it will go. To prevent
the piston in the drive unit from bottoming in its cylinder,
next turn the splined shaft about 5 deg in the opening
direction.
The position of the shaft now corresponds to the fully
closed position of the gate leaf. The hydraulic system is
now synchronized (set).
Caution: The splined shaft must not be moved from
its closed position until the gate leaf shoe that holds
the gate leaf has been attached.
INSTALL THE GATE LEAF SHOE
If the vertical distance between the finished grade
under the gate and the bottom of the gate leaf is
more than 1 1/4 in. (see Figure 4), you need to do one
of the following:
• Install a length of appropriately sized pipe
between the sleeve that fits around the splined
shaft of the operator and the gate leaf shoe.
• Construct a shear-pin assembly to accommodate
the extra vertical distance. The assembly is
welded to the bottom of the gate leaf shoe on one
end and to the sleeve for the splined shaft of the
pinion on the other end (see Figures 8 and 9).
Such an assembly requires a bottom hinge and
also protects the pinion and splined shaft in the
event something hits the gate with great force.
Installing the gate leaf shoe involves making the gate
leaf shoe, positioning it, and welding it to the splined
shaft sleeve. If you are retrofitting the 750 Operator
to an existing gate, these tasks require you to remove
the gate leaf from its hinges. If you are using a shearpin assembly, refer to Figures 9 and 10 to determine
what you should weld together.
The gate leaf shoe is designed to carry the weight of
the gate leaf and transfer the weight to the splined
shaft. The shoe surrounds the 90-deg gate-post
corner of the gate leaf to carry the gate and to act as
a lower hinge. The shoe is made of a U-shaped
section and a vertical section (see Figure 9). Later you
will weld the bottom of the U-shaped section to the
sleeve for the splined shaft (or to the shear-pin
assembly, which is welded to the sleeve).
Since the gate leaf shoe holds the gate leaf, both
sections must be made of steel at least 1/4 in. (0.6
cm) thick. The U-shaped section of the shoe must be
Figure 7. Connect the hydraulic line to the power unit.
See the technical drawing on page 21 for more infor-
mation.

Axis of rotation of the gate leaf
Weld this end of this pipe to
the bottom of the gate leaf
shoe, being certain you have
aligned the axes of rotation.
This 2 in. pipe (schedule 160)
has an inside diameter of 1.689 in.
Bolt or shear pin goes
through these holes and
the holes on the opposite
sides of the pipes.
Weld this end of this pipe to the
sleeve
for the splined shaft (do
weld anything to the splined shaft
itself). This 1 1/4 in. pipe (schedule
160) has an outside diameter of
1.660 in.
not
Figure 8. A sample shear-pin assembly
a minimum of 5 3/4 in. (2.1 cm) long and must be as
wide as the gate leaf is thick and must fit as tightly as
possible to minimize leaf movement within the shoe
(see Figure 9).
Construct the U-shaped section of the shoe and verify
that it fits around the gate leaf. Position the U-shaped
section over the splined shaft so that the leaf's axis of
rotation will fall within the minimum dimensions shown
in Figure 10.
On the U-shaped section of the shoe, mark the position
for the leaf's axis of rotation. Next, drill a pilot hole in
the U-shaped section to mark the axis of rotation point
and mark the position for the placement of the vertical
section of the shoe.
Next you need to position the sleeve for the splined
shaft of the pinion (or the shear-pin assembly) on the
bottom side of the U-shaped section of the shoe as
shown in Figure 9. On the bottom of the U-shaped
shoe section, center the sleeve around the pilot hole
that marks the axis or rotation. Accurately centering
the pilot hole is important.
Caution: NEVER weld the splined shaft to
anything.
Spot-weld the sleeve into place on the bottom of the
shoe's U-shaped section. If you are using the shear-pin
assembly, spot weld the sleeve to the bottom of the
shear-pin assembly, and spot weld the top of the
shear-pin assembly to the bottom of the shoe’s Ushaped section.
Next you must test the temporarily welded position of
the splined shaft's sleeve. Fit the shaft sleeve over the
splined shaft with the U-shaped section aligned in the
gate leaf's fully closed position. Verify with a plumb
line that the axis of rotation falls through the pilot
hole to the center of the splined shaft.
If the axis of rotation alignments are correct, then
permanently weld the sleeve for the splined shaft to
the bottom of the U-shaped section of the shoe.
Also, you now need to weld the pilot hole closed, and
you need to weld the vertical section of the shoe to
the U-shaped section of the shoe.
Lubricate the splined shaft with grease and place the
finished gate leaf shoe over the shaft in the closed
position.

If you are not using the telescoping shear-pin assembly,
install the gate leaf by placing its 90-deg corner into the
gate leaf shoe and then installing the top gate hinge.
Installing the top gate hinge may require the gate leaf
to be at a particular height. To raise (or lower) the gate
leaf to the proper height, equally adjust the four leveling
bolts on the base of the drive unit. The bolts raise (or
lower) the splined shaft and thus the gate leaf shoe and
gate leaf.
To test the installation of the gate leaf, first make sure
that the hydraulic system has been disengaged (the
Manual Release lever should point down).
Next, very slowly open and close the gate leaf a few
times to see if it moves smoothly and evenly through its
entire path. As necessary, adjust the leveling bolts on
the base of the drive unit to correct any problems with
the gate’s travel.
INSTALLING THE 455 D CONTROL

P
Installing the control panel consists of the following
general steps:
• Connecting the main power to the control
panel
• Connecting the activating device
• Connecting the operator to the control panel
• Checking the direction of the motor's rotation
• Connecting other devices to the control panel
• Set operating modes
The installer is responsible for grounding the gate and
operator systems, for providing the main power breaker

Instructions, see pages 22 - 33 of this manual.
BLEEDING THE HYDRAULIC SYSTEM
For the 750 Operator to work smoothly, it is critical that
you bleed the hydraulic system of any air. Before you
bleed the system, be sure that you have removed the
vent screw on the top, left side of the power unit.
One bleeding operation consists of the following:
• Running the gate leaf through three open-close
cycles
• Allowing the gate leaf system to sit idle for
5 minutes
• Releasing the air from each end of the drive unit
through the bleed screw holes (see Figure 1)
You need to bleed the hydraulic system before setting
the gate up for normal operation.
To run the gate leaf through an open-close cycle, make
sure the gate is set up for hydraulic operation (the
Manual Release lever is turned up) in the A mode.
Activate the gate once to open, pause, and then
automatically close. The gate needs to open and close
three times.
Then you need to allow the gate to sit idle for a full five
minutes. During this time, you can disengage the
hydraulic system (turn the Manual Release lever down)
and make sure that the top cover is removed from the
drive unit to allow you access to the bleed screws on
either end of the unit.
