# Installation

## Open The Enclosure

Use the 5mm hexagonal end of the T-shaped wrench to loosen the bolts on the top lid counterclockwise. It is not necessary to remove the bolts completely. 

The bolts are designed without center pins. This design facilitates safer and more efficient operation during outdoor use, particularly at elevated heights.

## Seal The Enclosure

Before closing the enclosure, ensure the orange gasket is in place, then press the lid down by hand.

1. Firstly, turn the two bolts near the lock hole clockwise. 
2. Then, tighten the other two bolts. 
3. Check the enclosure to ensure no gaps remain, and finally tighten all the bolts.
