4. Setup and Installation
Proper installation is crucial for the optimal performance and longevity of the concealed hinge. Refer to Figure 3.1 for precise measurements and hole placement.
Tools Required:
- Drill
- Drill bits appropriate for mounting screws (not included)
- Screwdriver (Phillips head recommended)
- Measuring tape or ruler
- Pencil or marker
Installation Steps:
- Prepare the Mounting Surface: Ensure the surfaces on both the cabinet frame and the inner door are clean, flat, and free of obstructions.
- Mark Drilling Points: Using the dimensions provided in Figure 3.1, accurately mark the drilling points for the hinge on both the cabinet frame and the inner door. Pay close attention to the "Long hole" dimensions for potential adjustment.
- Drill Pilot Holes: Drill pilot holes at the marked points. The size of the pilot holes should be slightly smaller than the diameter of your mounting screws to ensure a secure fit.
- Attach Hinges to Door: Secure one side of the hinge to the inner door using appropriate screws. Ensure the hinge is flush and aligned correctly.
- Attach Hinges to Cabinet Frame: Align the door with the cabinet opening and secure the other side of the hinge to the cabinet frame. It may be helpful to have assistance during this step to hold the door in place.
- Test Operation: Gently open and close the door to ensure smooth operation and proper alignment. Make any necessary adjustments using the elongated screw holes if present.

5. Operating Instructions
The FANGZHNHT concealed hinge operates on a four-axis folding mechanism, allowing the door to open and close smoothly while remaining hidden within the cabinet structure. To operate, simply open or close the cabinet door as usual. The hinge will articulate to allow the door to move freely and then fold compactly when the door is closed, maintaining a clean exterior appearance.

6. Maintenance
The 304 stainless steel construction of this hinge provides excellent resistance to corrosion and requires minimal maintenance. However, periodic inspection and cleaning can extend its lifespan and ensure smooth operation.
Maintenance Tips:
- Cleaning: Wipe the hinge surfaces periodically with a soft, damp cloth to remove dust and grime. For stubborn dirt, a mild soap solution can be used, followed by thorough drying. Avoid abrasive cleaners or harsh chemicals that could damage the stainless steel finish.
- Lubrication: While not typically required for this type of hinge, if you notice any stiffness or squeaking over time, a small amount of silicone-based lubricant can be applied to the pivot points. Avoid oil-based lubricants that can attract dust.
- Fastener Check: Periodically check all mounting screws to ensure they are tight. Loose screws can lead to misalignment or damage to the hinge and door.
7. Troubleshooting
If you encounter any issues with your FANGZHNHT concealed hinge, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Door does not close flush or is misaligned. | Loose mounting screws or incorrect initial alignment. | Tighten all mounting screws. If misalignment persists, loosen screws slightly, adjust door position, and re-tighten. Utilize elongated holes for fine adjustments if available. |
| Hinge feels stiff or makes noise. | Accumulation of dust/debris or lack of lubrication. | Clean the hinge mechanism thoroughly. Apply a small amount of silicone-based lubricant to the pivot points. |
| Hinge appears damaged or bent. | Excessive force applied to the door or impact. | If the hinge is physically damaged, it should be replaced to ensure proper function and safety. |
