ECHANISM
The Manual Release mechanism is a built-in release
device of the 412 Operator (see Figure 4). To access the
keyhole, remove the plug on the top of the motor
housing. Then insert the key and turn it a half turn in
the direction of the gate’s closing to disengage the
operator’s motorized operation. You can now move the
gate leaf by hand to open or close the gate. Operating
the gate leaf by hand is necessary during installation
and is useful during power failures.

Once you have prepared the gate, you are ready to
proceed with the installation of the operator.
Follow the instructions below to install your operator
whether in an inward or outward swinging
configuration.
Installing the operator consists of the following steps:
∗
Establishing the orientation of each gate leaf and its
operator.
∗
Attaching the rear mounting bracket
∗
Attaching the operator to the rear mounting bracket
∗
Attaching the front mounting bracket to the

Before you begin mounting brackets or attaching parts,
you first need to establish the proper orientation of
each operator in relation to its gate leaf.
Figure 2 (page 5) shows a biparting gate from the side
where the operators are mounted. The operator
attached to the hinge on the left of the gate must be an
SX model. If the hinge is on the right side, the DX
model must be installed.
Installing the operator on the wrong side makes it
impossible to install the protective cover of the
operator.

Inward swinging gate:
You need to determine whether to attach the rear
mounting bracket directly to the post (or wall) or to
notch the post and install a recessed liner. Large pillars
require a recessed liner to house the rear mounting
bracket and part of the operator so that the pillar will
not interfere with the swing of the gate when it is fully
opened.
To determine whether you need a recessed liner,
measure the distances B and D (shown in Fig. 5) on your
gate. If your measure of B or D is greater than the
dimensions shown for your operator in Figure 5, notch
the post and construct a recessed liner for the post
mounting bracket (see Figure 6). The recessed liner
should be constructed of 3/16 or 1/4 in. steel with a
minimum interior height of 11 13/16 in. (30 cm) so as
to allow you to meet the required dimensions shown in
Figure 5. Make sure the recessed liner is securely
embedded in the post (or wall).
There are two parts to the rear mounting bracket. The
horizontal bracket attaches to the operator, and the
slotted vertical plate attaches to the gate post (see
Figure 8). Weld the two parts together and bolt the
assembly to the gate post of column. Note, though, that
use of the vertical rear mounting plate is optional.
Once you have positioned the rear mounting bracket,
attach the bracket to the post (or wall or recessed liner),
making sure the dimensions on your gate system match
those shown in Figure 5.
