INSTALLATION Attach Operator to Gate 13 Installation Identify Hinge Type The illustrations below show common gate hinges. There are many styles of hinges available.
Installation 14 Measuring and Marking for the Gate Bracket Before proceeding, begin with the gate in the fully closed position. There are two methods described to determine proper location of the post brackets: • Paper template (to be cut out) located on the back page of this manual.
15 Installation Position the Extension Bracket to Post Bracket Hold post bracket in desired position. Align extension bracket to a position as CLOSE AS POSSIBLE above the marker. Assemble post bracket by placing the extension bracket on top of post bracket.
“Slowly extend the piston 1/4" (.64 cm) from collar and draw a mark.” THIS SIDE TO GA T E Screws Remove Motor Assembly Remove screws (4) and remove motor assembly. Set motor aside and place in clean, dry location. NOTE: Turn operator over to remove screws.
17 Installation Position Gate Bracket Hold the gate operator against the gate. The gate operator (arm) must be level. Clamp bracket to gate. Some installations require a reinforcement be installed on the gate. Attach Brackets to Gate Operator Attach post bracket to gate operator using hex head shoulder bolt and lock nut with nylon insert.
Check Piston Travel Visually check the clearance. Holding the gate firmly, slowly walk the gate to the fully open position. Check for pinch points at the post mount area. Allow a minimum of 1/4" between the post bracket and operator. Adjust gate bracket if the piston marks are not visible in both the open and close direction.
19 Installation Secure the post bracket to gate post using hardware. The gate operator (arm) must be level. Secure Gate Bracket to Gate Remove the operator from the brackets. Mark and drill holes in gate or reinforcement (if necessary) according to gate bracket mounting hardware.
Moving Gate Can Cause Injury or Death KEEP CLEAR! Gate may move at any time without prior warning. Do not let children operate the gate or play in the gate area.
21 Installation The control box MUST be mounted within 5' of the gate operator. Mount the control box as high as possible for best radio reception. Mount the Control Box Open the Control Box Remove screws and open the control box. RE SE T Remove the Control Board Disconnect reset button, alarm and coaxial connector.
Mount the Control Box Secure the control box to mounting surface (post, wall, column, etc.) using appropriate hardware (not provided). Install the Control Board Attach antenna. Reinstall batteries, control board, alarm, and reset button. Reconnect coaxial connector.

Occasionally in dual gate installations, one gate would need to open first and close second. This would happen if there was an ornamental overhang on one gate or if using a solenoid lock, for example. This gate is called the Primary gate and needs to be connected to Gate 1 connections on the control board.
Connect second Operator to Control Board (Model Ga420D Only) • Before digging, contact local underground utility locating companies. • Trench across driveway to bury the extension cable.
27 Wiring Junction Box The f ollowing items are required to complete the junction bo x (not provided) installation: • 4 x 4 Junction Box with 3/4 NPT threaded port holes • Screws • PVC Conduit Open the junction box by removing screws (4) and set aside.
Secure Junction Box Put wires inside of junction box. Secure operator and extension cables with watertight nut. Reinstall cover. Connect Wires in Junction Box Remove terminals from operator cable. Strip wires and twist like colored wires together with wire nuts.

31 Wiring Connect Batteries The batteries are charged in circuit by using the transformer (provided). Locate the two white battery plugs on the left-hand side of the control box. Connect the plug from the battery to connector on the control board. NOTES: Batteries will degrade over time depending on temperature and usage.
Test the limits by pressing the SBC to open and close the gate. NOTE: If the SET OPEN LIMIT LED is still blinking, the limits were not programmed successfully. Repeat the programming making sure the gate is fully opened and closed for each respective limit.
NOTES: • If one gate is overlapping the other, the gate that is overlapping must be connected to GATE 1 so it will start moving before the other gate; gate 2 may need to be closed fi rst if there is overlap or a gate lock is being used. • The programming can be exited at any time by pressing the RESET button.
Force/Timer to Close/Party Mode Controls Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing gate. • Too much force on gate will interfere with proper operation of safety reversal system.
