4. Operating the Case
Closing the Case
To ensure the IP66 splash-proof seal, make sure the lid is properly aligned with the base and both latches are securely fastened. A firm click indicates proper closure.
Water and Dust Protection
The HC-1810 is designed to protect against dust ingress and water splashes from any direction. This makes it suitable for use in environments where items might be exposed to rain, spray, or dust. However, it is crucial to understand that the case is not designed for submersion. Submerging the case in water may lead to leakage and damage to contents.

The case is designed to be IP66 splash-proof, protecting contents from water splashes and dust. It is not intended for full submersion.

Constructed from durable ABS resin, the hard shell provides robust external protection against impacts.
5. Maintenance
- Cleaning: Wipe the exterior of the case with a damp cloth. For stubborn dirt, a mild soap solution can be used. Ensure the case is completely dry before closing.
- Foam Care: The foam insert can be gently cleaned with a vacuum or a lint roller. Avoid harsh chemicals that may degrade the foam material.
- Seal Inspection: Periodically inspect the rubber seal around the lid for any signs of wear, cracks, or debris. A clean and intact seal is crucial for maintaining the IP66 rating.
- Storage: Store the case in a cool, dry place away from direct sunlight when not in use.
6. Troubleshooting
Padlock Compatibility
The padlock hole on the Lykus HC-1810 case has a diameter of approximately 0.18 inches. Please ensure that any padlock you intend to use has a hasp with a diameter of 0.18 inches or less to ensure proper fitment. Padlocks with larger hasps (e.g., 0.25 inches) will not fit.
