The DiaDorn Deposit Safe is designed for secure anchoring to a floor or wall. Proper installation is crucial for maximum security.
4.1 Unpacking:

- Check for any signs of damage during transit. If damaged, contact your supplier immediately.
- Verify that all components listed in Section 3. Product Overview are present.

The safe comes with pre-drilled holes at the back and bottom for anchoring. Use the provided heavy load anchors (steel dowels) for secure installation.
- Position the safe in the desired location.
- Mark the drilling points through the pre-drilled holes on the floor or wall.
- Move the safe aside and drill holes at the marked points using an appropriate drill bit for the anchors. Ensure the depth is sufficient for the anchors.
- Clean any dust or debris from the drilled holes.
- Reposition the safe over the drilled holes.
- Insert the heavy load anchors through the safe's holes and into the drilled holes.
- Tighten the anchors securely until the safe is firmly fixed to the surface. Do not overtighten.
