Benchy Sparkling Zero | Initial Startup Procedure
The Benchy Sparkling Zero should be set to to 2°C to ensure the sparkling/still water within the soda carbonator keg is cold without freezing the water lines or carbonated water. The unit should not be set below 2°C as there is a risk of the water freezing which can damage the Benchy Sparkling.
For detailed instructions on the operation of the temperature controller refer to the KegLand STC-1000 Instruction Manual
To check the set point termpature, press and release the Up button once. This will display the current set point temperature.
To change the set point temperature to the receommended setting of 2°C, press and hold the S button for at least 3 seconds to enter the parameter modifying mode. When the display shows parameter F1, Press the S Button again to show the current set point temperature. To change the set point press and hold the S Button and the Up or Down button until the desired set point temperature is displayed (2°C is the best setting). Once the desired temperature is displayed, press the Power button to confirm the temeprature setting otherwise it will not be saved.
Please review the previous steps to ensure everything is connected correctly and a leak test has been performed and passed.
Ensure the mains water supply and CO2 gas supply are turned off and the Benchy Sparkling is connected to your dispensing taps
Set the pressure on your CO2 regulator to your desired carbonation level (55psi recommended, no higher than 60psi). A higher gas pressure correlateds to a higher carbonation level and fizzier water. If you wish to have lower carbonation levels you will need to add a KL26918 6.35mm duotight - Inline Regulator with integrated gauge 0-150psi (1/4") in order to drop the water pressure such that there is a 10-15psi differential between CO2 presseure and water pressure.
Turn on the mains water pressure after double checking that the KL42925 - 6.35mm (1/4″) In Line Pressure Limiting Valve - 70psi (490kpa) - NSF Watermark is correctly installed.
Open your taps for a few seconds to purge any air which is in the hosing between the Benchy Sparkling and the tap
Enjoy a continuous supply of cold soda water and cold still water!
NOTE: The Benchy Sparkling will provide an uninterrupted supply of chilled and sparkling carbonated water. THE INITIAL CARBONATION MAY TAKE 24-48 HOURS AFTER SETUP. After this time carbonation will be continous.
If you do not have access to a mains water supply - for example if you are using tank water or bore water - we suggest using a 12V self-priming diaphragm pump to increase the water pressure to 10-15 psi above the pressure on your regulator.
A self priming pump such as the KL24433 Super Sucker - Siphon Pump (1/2' BSP) is ideal for this.
It is suggested that the pump you choose has an output pressure of at least 80psi and it has an auto pressure switch. The auto-pressure switch ensures that the pump provides a constant water pressure and switches off once that pressure
The included KL42925 - 6.35mm (1/4″) In Line Pressure Limiting Valve - 70psi (490kpa) - NSF Watermark will maintain a constant, regulated mains pressure of 70psi (in areas where mains pressure is >70psi), which is well suited to a carbonation level of ~55psi.
If you wish to have lower levels of carbonation, then the mains pressure must be regulated to a lower pressure. It is important to ensure that the pressure differential between the CO2 pressure and the regulate mains water pressure is maintained at ~15psi. Hence, to acheive a CO2 pressure of 40psi (for relateively lower carbonation levels) a KL26918 6.35mm duotight - Inline Regulator with integrated gauge 0-150psi (1/4') must be used in addition to the Pressure Limiting Valve to further regulate the mains water pressure down to 55psi (for example).
The KL26918 Inline Regulator needs to be installed after the Pressure Limiting Valve and before the Check Valve. Please refer to the Benchy Sparkling Under Counter Plumbing Diagram above
