Equipment Operation and Troubleshooting


Changing the Keg


  1. Remove the keg from the fridge.
  2. Lift the black handle of the coupler that connects to the top of the keg. This will disengage the keg, allowing you to remove the coupler without the product spraying from the keg. Make sure to keep this handle in the disengaged (up) position throughout changing process.
  3. Get a firm grip on the coupler and twist counter-clockwise about 45°. You should now feel the coupler detach from the keg.
  4. Line up the teeth on the bottom of the coupler with the slots on the top of the new keg. The coupler should be sitting flat, not on an angle on top of the keg.
  5. Proceed to twist the coupler about 45° clockwise this time.
  6. Once the coupler is firmly in place engage the new keg by pushing the black handle on the coupler back down. You will hear it click into place.

Changing a Gas Tank


  1. Turn off the gas by turning the valve on top of the tank clockwise until fully closed (valve will have open and close directional labels on top).
  2. Turn the red safety valve so that it is horizontal.
  3. Use a wrench to unscrew the brass nut on the regulator from the tank.
  4. Make sure the white plastic piece located inside the connection nut on the regulator is still in place, then proceed to tightly screw the regulator on to the new tank.
  5. Open the valve on the top of the gas tank by turning the top valve all the way counter-clockwise.
  6. Open the red shut off valve by moving it back to the vertical position.
  7. Check the gas pressure (PSI) on the top regulator gauge (35-40 PSI for Cold Brew, 5-10 PSI for Kombucha) and adjust accordingly.  






Troubleshooting


Scenario 1: Liquid is pouring out of the tap slowly with little or no Co2 or No2.

Possible issue 1: Empty keg

Diagnosis: Feel weight and gently shake keg

Solution: Change keg

Possible issue 2: Low PSI (gas pressure)

Diagnosis: Take a look at the corresponding gas tank: Co2 tank for Kombucha (the smaller tank inside fridge on two-tap units), or No2 tank for Cold Brew (the larger tank outside of the fridge on two-tap units). On the top of the corresponding tank there are two regulator gauges. The top gauge measures the gas pressure (PSI). For Kombucha this reading should be between 5-10 PSI, for Cold Brew it should be between 35-40 PSI. If the reading is below either of these ranges, the flow will slow down.

Solution: There is a flat head screw facing directly out from the regulator at the top of the gas tank. To increase the pressure, turn the screw clockwise (tighten) with a flathead screwdriver. The PSI reading on the gauge will start to increase as the screw tightens.


Scenario 2: No liquid is coming out of the tap.


Possible issue 1: Empty keg.

Diagnosis: Feel weight and gently shake to assess remaining liquid in keg.

Solution: Change keg.


Possible issue 2: Empty gas tank.

Diagnosis: Take a look at the corresponding gas tank: Co2 for Kombucha (the smaller tank inside the fridge on two tap units), or No2 for Cold Brew (the larger tank outside of the fridge on two-tap units). On the top of the corresponding tank there are two regulator gauges. The gauge on the side of the regulator measures the volume of gas in the tank. If this reading is 0, liquid will not come out of the faucet.

Solution: Change gas tank.


Possible issue 3: Shut off valve is closed.

Diagnosis: Check that the top black valve on the top of the corresponding gas tank is open.

Solution: Spin the valve all the way to the open position (counter-clockwise). The valve will have open and closed direction labels on it.

Possible issue 4: Safety valve is closed

Diagnosis: Check that the red shut off valve on the corresponding regulator is vertical (open).

Solution: Turn red shut off valve to vertical position if it is horizontal.
