HARACTERISTICS
The FAAC 422 Operator is an automatic gate operator
for a swinging gate leaf. It can accommodate a gate leaf
of up to 900 lb (410 kg) and up to 10 ft (3 m) in length.
The self-contained 422 Operator is an electro-hydraulic
unit consisting of an electric motor, a pump, a valve
assembly, and a hydraulic cylinder, all housed in an
anodized aluminum oil reservoir.
The 422 Operator can be used to swing the gate leaf
inward or outward. Most 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 422 SB
• The length of the gate leaf is 12 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 422 Operator, each gate
leaf on which it is installed must have a fixed positive
stop in both the opened and closed positions.
The 422 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 422 Operator.
The Manual Release mechanism is a key-operated
device that disengages (or engages) the hydraulic
system of the 422 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.
The two bypass valves are located beneath the locking
cap. You need to adjust the bypass valves to meet the
safety standards of FAAC International, Inc. The
standards state that the gate leaf should stop if it
encounters a force of more than 33 lb (15 kg).
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.

REPARING THE
G
ATE
Before installing the 422 Operator, you need to prepare
the gate itself for the operator. Be sure to do the
following things:
1. Make sure that the gate is plumb.
2. Make sure that the gate moves smoothly on its
hinges without excessive friction by swinging
it open and closed by hand. Lubricate all the
gates’ moving parts.
3. Provide positive stops for the gate leaves in
the fully open and fully closed positions (see
Figure 2).

NSTRUCTIONS
Installing the 422 Compact Operator involves preparing
the gate, installing the operator(s), installing the control
panel, and fine-tuning the pressure adjustments on the
operator(s).
Note: The following installation instructions
assume you are fully capable of installing an
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 422
Operator.
