Dual boiler system

• Simultaneously pull an espresso shot and steam milk – Steam is always readily available. Hence, there is no wait time going from coffee to steam mode.
• Insulation with stainless steel boiler – The boiler is made of stainless steel which is less susceptible to limescale. Typically stainless steel boilers do not retain their heat as well as copper or brass boilers. This machine compensates that by being wrapped with insulation This helps with temperature stability for the espresso extraction and also helps save energy.

E61 grouphead

• Pressure gauge from within – Gives a more accurate reading of brew pressure.
• Consistent heating – Hot water circulates from the boiler through the grouphead and back to keep the grouphead and your portafilter nice and hot. This keeps the grouphead at a constant, stable temperature compared to other groupheads that have a built-in heating element.
• Flow control capable – You can convert the grouphead and make it flow control capable via a kit sold separately.

PID control

• The PID display is used to program the temperature of both the coffee and steam boilers.
• Shot timer from within – As soon as you start the espresso extraction, you can view the shot time  on the display screen

Vibratory pump

• Profitable – Pumps will degrade in performance over time. Replacing a vibration pump will cost less than a rotary vane pump.
• Effective – 41 watts, rated up to 15 bar with air valve bypass. You only need 9 bar to extract perfect espresso, and wattage has no correlation to longevity.

Tank / reservoir system

• Automatic turn-off feature – Prevents burning out the heating element. The water tank sits on a spring-activated plate. Once the water is low, the plate depresses the tank microswitch which turns off the heating element.
• Particle filter – Protects the machine from any unseen particles from entering the boiler. You can remove this filter if you are installing an inline water softener.

Steam & hot water wand

• Multidirectional wands
• 2 hole steam tip – effective 8/1/2022, the steam tip has been changed from 3 to 2 hole.
• Hot water wand that is non-insulated
• Non-insulated steam wand goes faster throughout the steam.

Construction

• Drip tray –  The coffee side has a drip tray extender if you are using small espresso cups.  The right side of the front body is angled back. This gives more space for frothing and reduces the chance of burning yourself being further away from the grouphead.
• Body panel – Stainless steel that is polished to a mirrored finish. Some machines may have a white film which can and only should be removed after testing the Minima espresso machine with water

1. Upon receiving – We test this machine with water prior to shipping out. Your machine may arrive wet. Please let air dry for at least 24 hours prior to turning on. Also, there can be a white film left over the stainless, depending upon what the manufacturer does. Please do not remove the film until you confirm the machine has arrived in good working condition and without damage.
2. Flow control capable – You can convert the grouphead and make it flow control capable via a kit sold separately.
3. Some default settings of note:
   • Steam boiler safety valve is set at 2.5 bar
   • The max temperature is 255° Fahrenheit
   • OPV is set between 9-10 bar

General Espresso Machine Notes/Warnings:

• Upon first use (tank/reservoir models): On the initial start-up (or after a long period of non-use), it is important to make sure the pump is removing water from the tank. When the machine is powered on, you will hear the pump running. After 5 seconds, squeeze the in-line hose in the tank (usually the longest hose, has a particle filter attached). if you hear a different sound, this means the pump is working correctly. If not, immediately power down the machine and contact us. For more information, visit this page General Manual Pump Priming.
• Electrical: To avoid electrical damage to this espresso machine which is not considered a manufacturer's defect, please acquire and install a single-outlet surge suppressor rated at 1080 joules or higher. Without the recommended surge suppressor, the espresso machine can be damaged at the power switch, the electronics, the heating element, the pressurstat, or the wiring inside. For more information, visit this page Power Protection.
• Water: To increase the useful life and not damage your espresso machine, please use softened water. Softened water is water without calcium and magnesium, but still has other minerals for espresso extraction. Do not use distilled, purified, or reverse osmosis water as these types of water create oxidation with the metals and cause the same damaging effects as limescale. For more information, visit this page Water Choice.
• Descaling: We do not recommend descaling unless there is an issue with the espresso machine. Too much descaling can eat away at the metals and gaskets inside an espresso machine. As a preventative measure, we recommend using softened water as explained in the bullet point above.
• Backflushing: This procedure of cleaning the grouphead will need to be performed from time to time. For more information, visit this page Espresso Machine Backflush – Why 50?
