PAD MOUNTING
RETRO-FIT INSTALLATION
The operator is shipped from the factory with the lower mounting
angles configured out (Figure 1). If you have pad constrictions,
either angle can be unbolted and reversed to ‘angle in’.
NOTE: If you are replacing an SL540/SL570 and wish to use the
same pad mounting hardware, the gate side mounting angle must
be installed angle in.
NEW INSTALLATION
Concrete Pad Preparation:
1. Lay out concrete pad. (Figure 2).
2. Locate electrical conduit, as required, prior to pouring
concrete.
3. Pour concrete pad.
4. Secure operator (Figure 3) to the concrete pad using four 1/2"
concrete anchors (not provided).
