Setup and Installation
Installation of the Schlage F80-LAT lever set is designed to be straightforward and typically requires only a screwdriver. The set is compatible with standard door preparations.
Required Tools:
- Phillips Head Screwdriver
Pre-Installation Checks:
- Door Thickness: Ensure your door thickness is between 1-3/8" to 1-3/4".
- Backset: The latch bolt is adjustable for either 2-3/8" or 2-3/4" backset. Adjust as needed before installation.
- Handing: This lever set is field reversible, meaning it can be installed on both left-handed and right-handed doors. No special adjustments are needed for door handing prior to installation.
Installation Steps:
- Prepare the door by ensuring all necessary holes (cross bore, edge bore) are correctly drilled according to standard door preparation specifications.
- Install the latch bolt assembly into the edge bore of the door. Ensure the latch faceplate is flush with the door edge. Secure with screws.
- Insert the exterior lever assembly through the cross bore from the outside of the door.
- Align the interior lever assembly with the exterior assembly and the latch bolt.
- Secure both lever assemblies together using the provided mounting screws. Ensure the levers are level and operate smoothly.
- Install the strike plate and reinforcement plate on the door frame, aligning them with the latch bolt. Secure with screws.
- Test the operation of the lever set with the key from the exterior and by turning the interior lever.
Operating Instructions
The Schlage F80-LAT Latitude Storeroom Door Lever Set features a specific function designed for storeroom applications:
- Exterior Operation: The outside lever is always rigid and locked. Entry from the exterior is achieved by inserting the key into the cylinder and turning it to retract the latch bolt.
- Interior Operation: The inside lever is always free-turning and unlocked. Turning the inside lever will retract the latch bolt, allowing immediate egress without the need for a key.
Maintenance
Proper maintenance ensures the longevity and smooth operation of your Schlage door lever set.
- Cleaning: Clean the lever set with a soft, damp cloth. Avoid abrasive cleaners, solvents, or harsh chemicals, as these can damage the Satin Nickel finish.
- Lubrication: Periodically apply a small amount of graphite lubricant to the keyway if the key feels stiff or difficult to turn. Do not use oil-based lubricants, as they can attract dust and debris.
- Screw Tightness: Periodically check and tighten all mounting screws to ensure the lever set remains securely fastened to the door. Do not overtighten.
Troubleshooting
If you encounter issues with your Schlage F80-LAT lever set, refer to the following common problems and solutions:
- Lever is loose or wobbly: Check and tighten the mounting screws on both sides of the door. Ensure the internal components are properly aligned.
- Key is difficult to insert or turn: Apply graphite lubricant to the keyway. Ensure the key is fully inserted before turning. Check for any debris in the keyway.
- Latch bolt does not retract fully: Verify that the latch bolt assembly is installed correctly and moves freely. Check for any obstructions in the door frame or strike plate. Ensure the lever assemblies are not overtightened, which can bind the mechanism.
- Door does not latch: Ensure the strike plate on the door frame is correctly aligned with the latch bolt. Adjust the strike plate position if necessary.
