Assembling your NEO Flex
- Align the fins on the front and back of the base with the openings in the bottom of the post. Push down to seat.
- The Flair logo on the base and the NEO logo on the post must be on the same side.

Flow-Control vs. 2-in-1 Bottomless Portafilter
![]() |
Portafilter and Flow Control (Red), Includes Pressure Portafilter Everyone should start here! The Flow-Control Portafilter has a restricted outlet port that creates pressure to brew espresso in the chamber. This portafilter can be used with almost any grinder or coarse pre-ground coffee without having to "dial" your shot. Use for convenience. |
|
|
2-in-1 Bottomless Portafilter (Black) with Removable Spout Requires a quality coffee grinder! You will need to "tune in" or try different grind sizes until you get the right pressure. Grind too fine and you won't be able to lower the lever. Grind too coarse and the lever will lower without resistance and won't make espresso.

Preparing your NEO Flex for Brewing
- Separate Your Brew Head - Separate the brew head into four parts: 1) Piston, 2) Brew Cylinder, 3) Screen, 4) Portafilter. Tip: Use dosing cup to remove piston.
- Preheat the Brew Cylinder - Boil water. Add preheat cap to bottom of brew cylinder. Fill with boiled water. Leave for at least 30 seconds. Repeat as needed.
- Prepare your Freshly Roasted Beans - Start with 15 grams of beans or grounds (roughly 3 tablespoons). If grinding, do so right before brewing for the best results.
- Start with the Flow-Control Portafilter - When ready to brew with the Bottomless portafilter (black), an espresso capable burr grinder, and dialing-in, is required.

Pressure Release Valve
Your Flex comes with two “training discs” (red); one of which is installed in the plunger. Use this red disc when you have determined how much lever force is appropriate. The foil seal of the training disc (red) will break if excessive force is applied to the lever, indicating that your ground coffee is too fine. If the foil breaks, water will flow into the brew head. Repeat the test with a coarser grind (try the consistency of fine sea salt if using a Flow-Control Portafilter) and repeat the test with the second red disc.
Install the “grading disc” (black) when you are confident that the force applied is never excessive. If you are testing a new coffee with the measuring disc and feel that you are applying excessive force to the lever, carefully STOP brewing and start over with a coarser grind.
- Pressure Release Valve (Never Remove Foil)
- Broken Seal
*Remove the broken valve by pulling it out by the small recess at the edge of the valve. Replace by pushing new valve into the recess on underside of piston, with the foil facing out.

Cleaning your NEO Flex
Follow the steps below. Cleaning your NEO Flex should be done with water only. No soap is needed, as
it can affect your espresso’s taste. Never put your Flex parts in the dishwasher.
- Grip Here
- Lift lever and remove assembled Brew Head from NEO Flex frame, gripping the silicone where indicated above.
- Detach portafilter over sink by gripping portafilter in one hand and silicone on brew cylinder in other hand and pulling apart.
- Remove dispersion screen and eject grounds by knocking them out against the side of a trash can, or dig the grounds out with a utensil.
- Remove the piston using the dosing cup. Place cylinder over dosing cup and press down on a hard surface.
- Rinse all brewing parts with water from the tap. Reminder, don't use soap as it will impact your espresso's taste.

Troubleshooting your NEO Flex
We recommend periodically flushing your Flow-Control portafilter and brew head with fresh water. This
will prevent the build-up of any coffee residue and ensure optimum flow. Simply follow the brewing
steps, without coffee, to flush. For more thorough cleaning, remove the flow-control spout and rinse all
pieces with water, as shown below.
- Removable, replaceable spout to enable cleaning and declogging. Each Flex comes with an additional spout. Replace as necessary and if clogged.
- For cleaning: Unscrew the spout cap and rinse spout and bottom of portafilter in cool water. No soap is needed and may alter your espresso's taste.
