INSTALLATION PAD MOUNTING (SW470) 1. Layout the concrete pad (Figure 1). IMPORTANT NOTE: The relative location of the operator to the fence and the gate is critical. Be sure that the measurements for operator mounting are taken from the centerline of the fence and of the gate hinge. 2. Locate electrical conduit, as required, prior to pouring concrete. 3. Pour concrete pad. 4. Bolt the (2) pad mount brackets to the bottom of the operator with the hardware provided. 5. Secure the operator to the concrete pad. It is very important that the operator be level and square to the gate. Figure 1 Hinge Pin Fence c 9-3/4" 22-1/2" 24" 8" 1/2" Redhead (4 required.) Concrete pad 18"x34" min.

PAD MOUNTING (SW470)
1. Layout the concrete pad (Figure 1).
IMPORTANT NOTE:
The relative location of the operator to the
fence and the gate is critical. Be sure that the measurements for
operator mounting are taken from the centerline of the fence and
of the gate hinge.
2.
Locate electrical conduit, as required, prior to pouring concrete.
3. Pour concrete pad.
4.
Bolt the (2) pad mount brackets to the bottom of the operator
with the hardware provided.
5.
Secure the operator to the concrete pad. It is very important
that the operator be level and square to the gate.
