What is ReverseTap?
ReverseTap is an innovative beer dispensing system. It is an upward dispensing system,
different from the conventional downward dispensing system. ReverseTap dispenser
dispenses beer upward through the bottom of the cup. ReverseTap cup is uniquely
designed for this system with its patented plastic tension and sealing technology.
There are several benefits of ReverseTap compared to the conventional dispensing
system. 1) It maximizes the keg yield rate by preventing the loss of beer with its foam
amount control feature. 2) Its automatic amount control feature enhances the operator’s
productivity. 3) Its fast dispensing time enables the operator to sell more beer to more
people. It is extremely effective in a time-limited venues such as stadiums or concerts.
4) The novelty of upward dispensing concept itself is a powerful marketing tool to attract
more customers.
In conclusion, ReverseTap provides huge financial benefit to the users.

By executing this mode, the dispenser can measure and memorize the flow rate of the
beer during dispensing. Memorizing the flow rate is important because it will enable FOB
mode to work properly. This mode should be executed every time when there is a change
of system environment such as change of cooling machine, change of CO2 pressure rate,
and change of beer brand.
•Once entered into this mode, plug the cup into the dispenser

FOB Mode
FOB (Foam On Beer) refers to foam explosion. When the KEG is almost empty, only beer
foam is left in the KEG, and this foam will explosively come out of the dispenser. If users
activate FOB mode, this beer foam explosion can be prevented.
•On/Off : You can press Up and Down button to set the Mode
•Flow rate coefficient : You can change the value using Up and Down button
(Default value : 1.30)
•Meaning of Flow rate x 1.30 : FOB Mode will be activated when the speed of beer flow
becomes faster than 1.3 times of normal Flow rate
(Normal Flow rate is detected and memorized when Sync Mode is activated)
(Beer flow becomes faster when beer is dispensed together with foam)
•When the FOB Mode is activated, the below display will show up and stop dispensing
•Step-by-step procedure to replace with the new KEG

4) Close the middle valve of CO2 tank and replace the KEG with the new one
5) If you dispense a few cups of beer with the new KEG, those beer foam remaining in
the cooler and the tube will come out. 2-3 cups will be enough to remove all the
remaining foam
6) Once the foam is cleared, go to Mode Setting and turn on the FOB mode again
•If FOB Mode is activated even when the KEG is not empty, follow the below steps
1) Execute the Sync Mode to reset the flow rate of the dispenser
2) If FOB Mode is activated again even though the beer is not empty after Sync Mode
execution, change the flow rate coefficient number higher than 1.30 (ex. 1.40)
