Nanopresso has been manufactured using very high quality
materials that can be reused or recycled.
Dispose of the appliance in a suitable waste collection center.
FOR BEST RESULTS
Use fresh roasted coffee beans and filtered water.
Preheat all Nanopresso parts as well as your cup by running a cycle
with only hot water.
Grind coffee beans just prior to prepare your espresso shot.
Use a scales to measure the coffee grind quantity and make sure
the weight is equal to 8 grams.
Pump at the right tempo: one squeeze per second. Most types of
espresso shot (ristretto, single, double...) extraction takes 30 around
seconds. Don't hurry, take your time.
TROUBLESHOOT
Nanopresso integrates a new pumping system engineered
around the addition of a pressure release valve. When the pressure
inside the filter basket reaches 18 bar, the valve will open,
allowing the water back into the water tank. For a perfect
espresso shot, it's important to keep the pressure under 18 bar
and avoid any opening of this valve.
To do so, there are 3 parameters to control :
Coffee grind quantity. Too much coffee grind inside the filter
basket increases the inner pressure.
Coffee grind finesse. Too fine coffee grind increases the inner
pressure.
Pumping speed. A fast pumping action increases the inner
pressure.
If coffee does not come out or the flow is negligible at each
pumping :
Slow down your pumping speed.
Grind the bean a bit more coarsely. If you are using pre-ground
coffee, try to lower your tamping force or decrease slightly the
coffee grind quantity.
If the valve opened, wait few minutes before attempting to prepare
a new espresso shot..
