3. Setup and Installation
Proper installation is crucial for the secure and reliable operation of your paddle handle lock. Refer to the provided dimensions for accurate cutout and mounting.
Tools Required:
- Drill
- Appropriate drill bits (for pilot holes and mounting screws)
- Jigsaw or hole saw (for main cutout)
- Measuring tape or ruler
- Marker or pencil
- Screwdriver (Phillips or flathead, depending on mounting hardware)
- Safety glasses and gloves
Installation Steps:
- Prepare Mounting Surface: Identify the desired location for the lock on your RV door, truck tool box, or enclosure. Ensure the surface is flat and provides sufficient clearance for the lock mechanism on the interior side.
- Mark Cutout Area: Using the dimensions provided in Figure 3.1, carefully mark the rectangular cutout area and the circular hole for the key cylinder (if applicable) on your mounting surface. The main body requires a cutout of approximately 90mm x 106mm, with a depth of 34mm for the recessed portion. The key cylinder requires a 17.5mm diameter hole.
- Cut Opening: Carefully cut out the marked rectangular opening and drill the circular hole using appropriate tools. Ensure clean edges to prevent damage to the lock or mounting surface.
- Insert Lock Body: Insert the main body of the paddle handle lock into the prepared opening from the exterior side. Ensure it sits flush with the surface.
- Secure Lock: From the interior side, attach the mounting plate and secure the lock using appropriate screws or bolts. Tighten fasteners evenly to prevent distortion.
- Connect Wiring (if 12V): If your model includes 12V functionality (e.g., for central locking or alarm integration), connect the wiring according to your vehicle's or system's electrical diagram. Ensure proper polarity and insulation.
- Test Operation: Before fully closing the enclosure, test the lock's operation. Ensure the paddle handle moves freely, the latch engages and disengages smoothly, and the key cylinder (if present) operates correctly.

4. Operating Instructions
Operating the RFXCOM Recessed Zinc Alloy Paddle Handle Lock is straightforward.
To Unlock:

To Lock:
- Close the door or lid firmly until the latch engages with the strike plate.
- Insert the key into the key cylinder and turn to the lock position. Remove the key.
- Verify that the lock is engaged by attempting to open the door or lid without pressing the paddle handle.
5. Maintenance
Regular maintenance will help ensure the smooth operation and extend the lifespan of your RFXCOM paddle handle lock.
- Cleaning: Clean the exterior of the lock periodically with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish.
- Lubrication: Apply a small amount of graphite lubricant or a silicone-based spray lubricant to the key cylinder and internal moving parts of the latch mechanism once or twice a year, or as needed in harsh environments. Do not use oil-based lubricants as they can attract dirt.
- Inspection: Periodically inspect the lock for any signs of wear, damage, or loose mounting screws. Tighten any loose fasteners.
- Corrosion Prevention: For locks exposed to moisture or corrosive environments, consider applying a thin layer of protective wax or silicone spray to metal surfaces after cleaning.
