This replacement water tank is compatible with the 3b Luna Series & Resmart GII Series cpap machine.
The water chamber tub is a replacement chamber that is used with the 3b Luna / RESmart GII H60 heated humidifier and is integrated with the 3b Luna / RESmart GII CPAP machine. Do not fill the hole on the top of the chamber with water.
Turn to view the underside of the water chamber to locate the small dial on the front left side of the chamber.
With the bottom facing upward, turn the water inlet cap in a counterclockwise direction until the arrow on the cap is facing the triangular mark by the opening.
Release any residual water still sitting in the chamber to make sure all of the water is fresh.
Add approximately 350mL of water into the water inlet.
