Setup

1. Unpacking

Carefully remove all components from the packaging. Ensure all protective films and packaging materials are removed from the machine before use. Place the machine on a stable, level surface away from direct sunlight and heat sources.

2. Water Tank and Filter

The J8 Twin features a removable water tank with a capacity of 64 fluid ounces, located on the side of the machine. It includes a filter designed to improve water quality and reduce the need for descaling. Before first use, test your home's water hardness level using the provided test strip and program it into the machine. Fill the water tank with fresh, cold water.

3. Bean Hoppers and Grinders

The J8 Twin is equipped with two separate 6.3-ounce bean containers, each with its own high-performance conical grinder. This allows for the use of two different types of coffee beans (e.g., regular and decaf) without mixing. Adjust the grind intensity for each grinder using the aroma control dials located on top of the machine. A finer grind typically results in a stronger coffee.
