4. Setup and Installation
The MOTTURA Serie Personal Under 11.1331 is designed as a wall safe, requiring professional installation into a suitable wall structure. Incorrect installation can severely compromise the safe's security and stability. If you are unsure about any step, consult a qualified professional.
4.1. Choosing a Location
- Select a location in a structurally sound wall (e.g., brick, concrete, or reinforced stud wall).
- Consider a discreet or concealed location for added security.
- Ensure there are no electrical wires, plumbing, or other obstructions within the wall at the chosen installation site.
4.2. Required Tools (Not Supplied)
- Measuring tape and pencil
- Level
- Angle grinder or wall saw (for cutting wall opening)
- Drill with appropriate masonry bits
- Hammer
- Wrench/Spanner (for anchor bolts)
- Protective gear (gloves, safety glasses, dust mask)
4.3. Installation Steps (General Guidance)
- Mark and Cut Opening: Carefully measure the safe's external dimensions (H.395 L 495 T 325 mm) and mark the precise opening on the wall. Cut the opening using appropriate tools, ensuring a snug fit for the safe body.
- Prepare Cavity: Clear any debris from the wall cavity. Ensure the cavity is deep enough to accommodate the safe's depth (325 mm) and allow for flush mounting.
- Insert Safe: Carefully slide the safe into the prepared wall opening. Use a level to ensure it is perfectly horizontal and vertical.
- Secure Anchoring: The safe features pre-drilled holes for anchoring. Mark the positions of these holes on the wall. Remove the safe, drill pilot holes into the wall, and then re-insert the safe. Secure it firmly using the provided anchor bolts and washers. Tighten all bolts securely.
- Finish Wall: Once the safe is securely anchored, finish the surrounding wall area with plaster, drywall, or other suitable material to conceal the installation and integrate the safe seamlessly.
Important: Always ensure the safe door is closed and locked during installation to prevent accidental opening or damage.
5. Operation
The MOTTURA Serie Personal Under 11.1331 safe uses a high-security double-bit key lock.
5.1. Opening the Safe
- Insert one of the supplied double-bit keys fully into the keyhole.
- Turn the key clockwise (or counter-clockwise, depending on the specific lock mechanism) until the locking bolts retract. You should feel a distinct click.
- Pull the door open.
5.2. Closing and Locking the Safe
- Ensure all items are placed inside the safe and nothing obstructs the door from closing completely.
- Close the safe door firmly.
- Insert the key into the keyhole.
- Turn the key counter-clockwise (or clockwise) until the locking bolts extend and the door is securely locked.
- Remove the key and store it in a secure, separate location.
Key Management: It is highly recommended to keep one key as a spare in a very secure, separate location, not inside the safe. Never give keys to unauthorized persons.
6. Maintenance
Regular, simple maintenance will help ensure the smooth operation and longevity of your MOTTURA safe.
- Cleaning: Wipe the exterior of the safe with a soft, damp cloth. Avoid abrasive cleaners or solvents, as these can damage the finish.
- Lock Mechanism: The key lock mechanism is designed for maintenance-free operation. Do not apply oil, grease, or any lubricants into the keyhole or locking mechanism, as this can attract dust and cause malfunctions. Keep the keyhole clean and free of debris.
- Door Hinges: Periodically check the door hinges for any signs of wear or looseness. If the door does not open or close smoothly, contact customer support.
- Mounting Security: Occasionally check the security of the safe's mounting. Ensure all anchor bolts remain tight and the safe is firmly fixed in the wall.
