- For the Front Panel:
- Unscrew the reversing screw on the front panel.
- Turn the handle to the desired opening direction.
- Put the reversing screw back and tighten it.
- For the Rear Panel:
- Unscrew the reversing screw on the rear panel.
- Turn the handle to the desired opening direction.
- Put the reversing screw back and tighten it.
Important: When installing the rear lock, the arrow marking and handle should be in the opposite direction to the front lock's handle.
3.2. Installing Pads and Solenoid
- Install the Front Locking Rubber Pad onto the front panel.
- Mount the solenoid into the front panel and tighten it with pliers.
- Fit the Rear Locking Spacer with its corresponding rubber pad.
3.3. Preparing the Door

The lock supports various mortise sizes like 240x22 (6085), 240x22 (5085), 240x22 (4585), 240x22 (4085), 240x22 (3585), 240x22 (3085), SG-270x22 (3585), SG-270x22 (2885), 240x22 (7085).
3.4. Installing the Lock Body and Panels
- Insert the lock body into the door.
- Secure the lock body with fasteners using a drill.
- Run the power wire through the door hole from the front panel.
- Insert the square rod into the front panel, aligning it with the round hole position.
