5. Installation Guide
The ARREGUI 22100-S1 safe box is designed for hidden installation, typically under a kitchen cabinet or within a plinth. Professional installation is recommended.
5.1. Preparation
- Choose Location: Select a suitable location under a cabinet or within a plinth that can accommodate the safe's dimensions (17.72"D x 16.14"W x 5.83"H). Ensure there is sufficient clearance for the drawer to open fully.
- Gather Tools: You will need a drill, appropriate drill bits for your cabinet material, a wrench, a measuring tape, a marker, and safety glasses.
- Clear Area: Ensure the installation area is clean and free of obstructions.
5.2. Mounting the Safe
The safe is mounted using a separate plate that attaches to the underside of your cabinet or plinth base.
- Position Mounting Plate: Place the mounting plate (as shown in Image 5.1) in the desired installation location. Mark the positions for drilling holes through the plate onto the cabinet base.
- Drill Holes: Carefully drill pilot holes through the marked positions on the cabinet base. Ensure the drill bit size is appropriate for the mounting bolts.

7. Maintenance
To ensure the longevity and smooth operation of your ARREGUI safe box, follow these simple maintenance guidelines:
- Cleaning: Wipe the exterior and interior surfaces with a soft, dry cloth. Avoid abrasive cleaners or solvents that could damage the finish.
- Lock Mechanism: Periodically apply a small amount of graphite lubricant (not oil-based) to the keyhole to ensure smooth key insertion and turning. Do not over-lubricate.
- Drawer Rails: Keep the drawer rails clean and free of debris. If the drawer movement becomes stiff, a light application of silicone spray lubricant on the rails can help.
- Key Care: Store spare keys in a safe, memorable location away from the safe itself. Avoid bending or damaging the keys.
8. Troubleshooting
If you encounter any issues with your ARREGUI 22100-S1 safe box, please refer to the following common problems and solutions:
- Drawer is Stiff or Not Opening/Closing Smoothly:
a. Check for any obstructions in the drawer rails or within the safe compartment.
b. Ensure the safe is installed level and square. Uneven installation can cause binding.
c. Clean and lightly lubricate the drawer rails as described in the Maintenance section. - Key is Difficult to Turn or Insert:
a. Ensure the key is fully inserted into the lock cylinder.
b. Apply a small amount of graphite lubricant to the keyhole.
c. Check if the key is bent or damaged. Use a spare key if available. - Safe Not Locking:
a. Ensure the drawer is fully closed and flush with the safe body.
