2.2. INSTALLATION DIMENSIONS
2.1. PRELIMINARY CHECKS
To ensure a correctly operating automated system, the structure
of the existing gate or gate to be built must satisfy the following
requirements:
• Leaf dimensions are within the limits specified in Table 1
• The gate swings level
• Smooth, uniform leaf movement, without any irregular friction
during the entire travel
• Existing hinges in good condition
• Positive stops are provided in the fully opened and closed
positions

GENERAL RULES
If the dimensions indicated in table A or B cannot be obtai-
ned the following general rules can be used determine diffe-
rent installation dimensions:
- to obtain 90° opening of the leaf: a + b = rod stroke.
- to obtain over 90° opening of the leaf: a + b < rod stroke.
- lower a and b dimensions will result in higher speeds.
- limit the difference of the a and b dimensions to within
1.5 in, higher differences will create high speed variations
during the opening and closing movement;
- if the column dimensions or the position of the hinge (di-
mension D) do not make it possible to reach the required
A dimension, a niche must be carved in the column as
shown in Fig. 5;
(1) Length of dimension “A” - 2 in.
(2) Length of dimension “B” + 4 in.
2.4. INSTALLATION OF THE OPERATOR
Installing the model 422 operator consists of the following
steps:
1. Attach the rear mounting bracket
2. Attach the operator to the rear mounting bracket
3. Attach the front mounting bracket to the operator
4. Attach the operator to the gate
5. Adjust the hydraulic pressures for the operator
