4. Setup and Installation
The Phillips 549 ABL Mortise Lock is designed for installation into aluminum door profiles. Detailed installation instructions are typically provided with the product. The following steps outline the general procedure:
- Prepare the Door: Ensure the aluminum door profile has the correct mortise cutout for the lock body and appropriate holes for the spindle, key cylinder, and mounting screws. Refer to the provided template (if included) for precise measurements.
- Insert the Mortise Body: Slide the main lock body into the prepared mortise cutout in the door edge. Secure it with the provided screws through the faceplate.
- Install the Key Cylinder: Insert the key cylinder through the designated hole in the door and into the lock body. Secure it with the cylinder screw from the door edge.

6. Maintenance
Regular maintenance ensures the longevity and smooth operation of your lock:
- Cleaning: Wipe the exterior surfaces of the lock with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish.
- Lubrication: Periodically (e.g., once a year), apply a small amount of graphite-based lubricant or a silicone-free lock lubricant into the keyway and moving parts of the latch and deadbolt mechanism. Do not use oil-based lubricants, as they can attract dirt and dust.
- Tighten Screws: Check all mounting screws periodically and tighten them if they have become loose.
- Inspect: Regularly inspect the lock for any signs of wear, damage, or misalignment.
