Setup and Installation
Tools Required:
- Phillips Head Screwdriver
- Measuring Tape
- Pencil
- Drill (if new installation)
- Chisel (if new installation)
Installation Steps:
- Prepare the Door: If installing on a new door, mark and drill holes according to the provided template (not included in this manual, refer to manufacturer's template). Ensure the mortise pocket is correctly sized for the deadlock body.
- Install the Deadlock Body: Insert the mortise deadlock body into the prepared mortise pocket in the door edge. Secure it with the appropriate screws. Ensure the deadbolt extends and retracts smoothly.
- Install the Cylinders: Insert the 6-pin cylinders into the lock body from both sides of the door. Align the tailpieces with the mechanism inside the lock body. Secure the cylinders with the cylinder screws or retaining rings as per the design.
- Install the Trim (if applicable): Attach any decorative trim plates or escutcheons over the cylinders, securing them with the provided fasteners.
- Install the Strike Plate: Close the door and mark the position of the deadbolt on the door frame. Chisel out a recess for the strike plate and secure it with screws. Ensure the deadbolt fully extends into the strike plate opening without obstruction.
- Test Operation: With the door open, insert a key into each cylinder and turn to extend and retract the deadbolt. Repeat with the door closed to ensure smooth operation and proper engagement with the strike plate.
Operating Instructions
The Corbin Russwin DL4112-626 is a double cylinder mortise deadlock, meaning it requires a key to lock and unlock from both the interior and exterior sides of the door.
- To Lock: Insert the key into the cylinder on either side of the door. Turn the key to extend the deadbolt fully into the strike plate. Remove the key.
- To Unlock: Insert the key into the cylinder on either side of the door. Turn the key to retract the deadbolt fully from the strike plate. Remove the key.
Always ensure the deadbolt is fully extended or retracted for optimal security and smooth operation.
Maintenance
Regular maintenance will help ensure the longevity and smooth operation of your deadlock.
- Cleaning: Clean the exterior surfaces of the lock with a soft, damp cloth. Avoid abrasive cleaners or solvents, as these can damage the finish.
- Lubrication: Periodically (e.g., once a year or if operation becomes stiff), apply a small amount of graphite-based lubricant or a silicone-based spray lubricant specifically designed for locks into the keyway and around the deadbolt mechanism. Do not use oil-based lubricants, as they can attract dirt and dust.
- Inspection: Periodically check all mounting screws for tightness. Ensure the deadbolt moves freely and the strike plate is securely fastened.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Key is difficult to insert or turn. | Dirt or debris in keyway; worn key; lack of lubrication. | Clean keyway with compressed air. Lubricate keyway with graphite or silicone-based lock lubricant. Try a spare key. |
| Deadbolt does not extend or retract smoothly. | Misalignment with strike plate; loose screws; internal mechanism obstruction. | Check strike plate alignment and adjust if necessary. Tighten all mounting screws. Lubricate the deadbolt mechanism. |
| Deadbolt does not fully engage the strike plate. | Door or frame has shifted; strike plate misalignment. | Inspect door and frame for warping or settling. Adjust strike plate position. |
