USER GUIDE

Dispensing Coffee

The left tap delivers still cold brew which is refreshing and less acidic than hot coffee. The right tap delivers nitrogen-infused
coffee which is the ultimate cold brew experience. Thousands of micro-nitrogen bubbles are infused as the coffee is dis-
pensed. This creates a naturally slightly sweet taste and thicker and smoother texture.

SOLUTION
See cleaning section
If applicable, assure that the nitrogen tank is not empty and
that the nitrogen shutoff switch is in the on position (in-line with
the tube). Also assure that the knob on top of the tank is turned
all the way counterclockwise. If the tank is empty, replace it
with a full one.
Attach the liquid/nitrogen ball lock disconnects to the product
tank. If they already appear to be connected, disconnect/
reconnect them.
Detach the nose cone assembly from the stout faucet by turning
it counterclockwise. Remove the stainless steel restrictor disc
and inspect the small holes to assure that none of them are
clogged.
Follow the line cleaning procedure above to remove buildup and
restore full flow.
If there is less/more nitro effect than desired, use the black
knob on the secondary regulator assembly to make a change.
To adjust the secondary regulator, pull the black knob out until
you feel a slight click. This is the adjustment mode. To increase
the level of nitro, turn this knob clockwise. To decrease the level
of nitro, turn the knob counterclockwise. Continue adjusting and
pouring until the level of nitro meets your requirements. Once
you have found your desired level of nitrogenation, push the
black knob back in to lock it in place.
