Frequently Asked Questions - BVB4 CDA

How do I connect the CO2 cylinder to the CDA BVB4 beer dispenser?

First, ensure the dispenser is turned off. Connect the CO2 regulator to the cylinder, then attach the gas line to the inlet on the back of the dispenser. Open the cylinder valve slowly and check for leaks. Adjust the pressure according to the manual (typically 2-3 bar).

What kegs are compatible with the BVB4?

The CDA BVB4 is designed for standard 5-liter mini kegs, but it can also accommodate large 20-liter kegs with the appropriate adapter. Always check the keg size and type before use.

How do I clean the beer dispenser?

Unplug the unit and wait for it to warm up. Remove the keg and drip tray. Wash the tap and tray with warm soapy water. Use a cleaning solution (e.g., beer line cleaner) to flush the internal lines. Rinse thoroughly with water before reattaching.

Why is my beer not cold enough?

Ensure the temperature setting is at the desired level (2-8 °C). Allow the dispenser to cool down for at least 4 hours after plugging in. If the problem persists, check if the vents are blocked or if the compressor is working properly.

How do I adjust the foam level?

The tap has an adjustable flow control. For less foam, open the tap fully; for more foam, partially close it. Also, ensure the CO2 pressure is set correctly—too high pressure causes excess foam.

What should I do if the beer won't dispense?

Check that the CO2 cylinder is turned on and has gas. Ensure the keg is properly connected and not empty. If the system is clogged, clean the tap and lines. Also, verify the power supply and that the cooling system is running.

Can I use the BVB4 for other beverages?

The BVB4 is specifically designed for beer and may not maintain the carbonation levels for soft drinks or wine. However, you can use it for pre-carbonated beverages if the keg is compatible.

How often should I replace the CO2 cylinder?

The frequency depends on usage. A standard 5-liter CO2 cylinder (e.g., 16g) can dispense about 5-10 kegs. When the beer flow slows or stops, replace the cylinder.

Is the beer dispenser energy efficient?

The CDA BVB4 consumes approximately 80W, making it relatively efficient for its size. It cycles on and off to maintain temperature, but leaving it on 24/7 may increase energy usage. Consider unplugging when not in use.

Where can I find spare parts for the BVB4?

Spare parts such as taps, drip trays, gaskets, and regulators are available through authorized CDA dealers or online retailers. Use the model number BVB4 when ordering.

6. CONNECTING AND REPLACING THE CO ^2 CYLINDER

CAUTION: The cylinder contains high pressure CO ^2 gas, pressurised to approximately 230 bar.

Handle the cylinder with the utmost care and always close tap "O" (fig. 1) even when the cylinder is empty. Taps "O" and "S" (fig. 1) should be kept closed, even when the machine is not used.

Do not open the cylinder tap (valve) until all items, including the dispense head "I" (fi g. 1) have been connected.

To connect the CO ^2 cylinder, proceed as follows:

• Close tap "S" (fi g. 3).
• Remove the seal from the cylinder.
• Fit the CO ^2 outlet nozzle of the cylinder to the attachment with the reducer manual clamp.
• Tighten carefully, screwing down the manual clamp device until it is firmly secured.
• Tighten the cylinder straps "L" (fi g. 3).
• Open tap "O" (valve) (fi g. 3).
• Open tap "S" (fi g. 3).

To remove the empty cylinder, proceed as follow:

• Close tap "O" (valve) (fi g. 3).
• Close tap "S" (fi g. 3).
• Release the cylinder straps "L" (fi g. 3).
• Loosen the manual clamp device until the cylinder is completely released.

(Fig. 3)

7. REGULATING CO ^2 , TEMPERATURE AND SERVING BEER

Important: Beer is not a drink for children. Children should only have access to the dispenser under the strict supervision of their parents or responsible adults.

If children are at home alone, close taps "O" and "S" (fi g. 1) and remove the dispense head "I" (fi g. 1) from the keg.

Beer will keep for approximately 8 days after a new keg has been opened. However this can differ per brand and type of beer. Check for accurate durability after opening the keg with your keg supplier.

Beer quickly deteriorates, posing a hazard (bacteria develop), so the dispenser should be washed and disinfected regularly. This should preferably be done every time the keg is changed or at least every 15 days.

A dispenser with stale beer residues can smell unpleasant and give the beer an unpleasant taste. The beer in a new keg, connected to a dirty dispenser, is quickly contaminated if bacteria are present, and even if a new keg is connected, the beer acquires an unpleasant taste. Carefully follow the instructions for “washing and disinfecting the dispenser”.

C D A shall not be held liable in any way for damage caused to people or objects as a result of failure to comply with the above.

REGULATING CO ^2 PRESSURE

Caution: Do not disassemble or tamper with the pressure reducer.

The high pressure of CO^2 is lowered to a set value using the adjusting screw “R” (fi g. 1) on the pressure reducer.

The pressure value is configured based on the temperature that the keg and type of beer (Pils or Lager) is exposed to.

The wrong pressure regulation will make the beer too frothy or under carbonated (dull beer or with little froth).

N.B. If the pressure is too low for the keg temperature, the beer will be served very frothy. To regulate pressure, see the values in the table (table 1).

The table (tab. 1) shows the pressure to use.

• Open taps "S" and "O" (fi g. 1).
  • Make sure all fittings and connections are properly sealed and that there are no CO ^2 leaks. If there are leaks, close taps “O” and “S” (fig. 1) and check the cause of the leak.
• Read and take note of the temperature on the thermometer "T" (fi g. 1).
• Check the pressure to select, from the table.
• The pressure is indicated by the hand on the pressure gauge "Q" (fi g. 1).
  • Turn the adjusting screw clockwise or anticlockwise until the hand on the pressure gauge "Q" (fig. 1) is on the selected value.
• Secure the adjusting screw using the lock nut below the screw.

N.B. The pressure gauge "U" (fig. 1) indicates cylinder pressure. When the hand (with the tap "O" (fig. 1) open) drops to the red zone, the cylinder is empty. A full cylinder will serve approximately 50 litres of beer.

To replace, see chapter CONNECTING AND REPLACING THE CO ^2 CYLINDER

(table 1)

The dispenser can serve beer at a temperature from approximately 4^ C to 8^ C. This value is affected by the temperature of the keg, which must not be stored at a temperature above 25^ C. If the temperature is higher than 25^ C, the dispenser cannot serve beer properly (too much froth and beer flowing unevenly).

- Turn knob "C" (fig. 1) clockwise to lower the temperature, or anticlockwise to increase the temperature. Turn the knob to the desired temperature and keep in position, even when the machine is turned off.

SERVING BEER

As the dispenser consumes little energy, we recommend leaving it turned on. The beer in the circuits will not heat up and will not deteriorate. Besides an unpleasant taste, bacteria harmful to health could grow.

• Turn on the dispenser and the lighting, turning knob "A" (figure 1) to position "I".
  • After around 5 minutes, the dispenser is ready to serve beer at temperature from approximately 4°C to 8°C.

! We recommend rinsing glasses with cold water (draining them rather than drying them), before serving the beer. This will cool the beer and maintain its serving temperature for longer.

Serving beer:

• Pull the tap entirely towards you, quickly and firmly. Be sure not to keep the tap halfway open, for this way only froth will come out of the tap.
- As soon as you see the beer flowing out of the tap, put the glass underneath and tilt.
• This needs a little practice, as it should be done quickly.
- Gradually straighten the glass while it is being filled, until it is nearly in an upright position.

N.B. If you want a froth "decoration" or extra froth, move the tap very slightly towards you, so only froth will come out.

Important: When the dispenser is not in use, it must be washed and disinfected (see the next chapter "WASHING AND DISINFECTING THE DISPENSER") and the circuits emptied. Open the tap handle and drain the water left in the circuits from the dispense head, after removing it from the key.
