CDA BVB4 manual Regulating Beer Temperature, Serving Beer, Maintenance and Cleaning

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” (fig. 1).

•Make sure all fittings and connections are properly sealed and that there are no CO² 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” (fig. 1).

•Check the pressure to select, from the table.

•The pressure is indicated by the hand on the pressure gauge “Q” (fig. 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.

REGULATING BEER TEMPERATURE

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 unplea- sant 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 keg.
