All about GROHE Blue Professional


GROHE Blue Home is the solution for the home and non-commercial use. GROHE Blue Professional is the business solution but can also be used at home. The difference lies in the systems’ capacities. The GROHE Blue Professional cooler is designed to deliver 12 liters of chilled and sparkling water per hour, which is enough for a larger group of up to 40 users.
The kitchen cabinet must have a minimum width of 600 mm and a minimum depth of 500 mm. The cabinet opening must be at least 430 mm tall. Please note that additional ventilation holes are needed for aerating of the cooler. Watch our installation video for more details.
The cooler is required for the carbonation of carbon dioxide in drinking water and is therefore necessary for the production of carbon dioxide in drinking water. The colder the water, the more carbon dioxide can be bound. Moreover, the cooler should not be switched off for hygiene and contamination reasons!
The water temperature at the cooler can be set between 5 and 10 °C. The colder the water, the more carbon dioxide can be bound in it. This means that an increase in temperature has an impact on the water’s CO2 content.
The GROHE Blue faucet provides filtered still water (top button) or filtered sparkling water (lower button). If you press both buttons in sequence, the faucet provides medium sparkling water.

However, carbon dioxide binding in water is affected by various factors. The colder the water from the cooler, the more carbon dioxide can be bound. Another factor is the local carbonate hardness (°dKH) of the water.
The GROHE Blue Professional kit contains a GROHE Blue Professional single-lever sink mixer with filter function, a GROHE Blue Professional cooler with Bluetooth and WIFI interface, a filter head with flexible water hardness adjustment, a cleaning cartridge adapter, a pressure indicator for 2 kg bottles and installation material. Not included are a GROHE Blue filter, a CO2 bottle and a cleaning cartridge. Those items have to be ordered separately.
CO2 bottles, filters and cleaning cartridges are easy to purchase from our online shop. We offer a refill system for original GROHE CO2 bottles so that you will never run out of bubbles.
If you require larger quantities of bottles, then please get in contact with our customer service.
If the carbonate hardness is below 9° dKH, the activated carbon filter should be used in any case, as this will not make the water even softer. For carbonate hardness greater 9° dKH, you can use the standard filter (S Size, M Size or L Size) or the Magnesium + Zinc filter.

To remove even microplastic (> 1µm) and 99,999% of bacteria, you choose the UltraSafe filter.

We recommend cleaning your GROHE Blue Professional with our GROHE cleaning cartridge every time you change the filter, or at least twice a year.
GROHE Blue Professional can be used with a GROHE 2kg CO2 bottle which must be purchased separately. A 2 kg CO2 bottle is enough to provide up to 350 liters of sparkling water. The watersystem can also be connected to our 425gr CO2.
With the parts enclosed with the GROHE Blue system, the maximum distance permitted between the tap and the cooler is 75 cm. With the help of the separate extension set (item no. 40843000), it is possible to install it at a distance of up to 5 m. This means you can also place the cooler in an adjacent room or a cellar room that is situated underneath. Please note, however, that the hose extension should be kept as short as possible.
If you require a solution for low pressure, in addition to your existing low pressure tap, you can use the GROHE Blue Mono tap. Your kitchen sink would have two taps. Another alternative would be a combination with our GROHE Red. In this case, the existing low pressure boiler with tap would be replaced by our GROHE Red with its boiling water boiler and the special accessory GROHE Red mixing valve. Your sink would have two taps in this solution, too.
Here you can use our GROHE Switch (item no. 40402000), a battery-operated stop valve for dishwashers, as an accessory.
Yes, you must ensure there are openings for ventilating and aerating the cooler. Please watch our installation video for more details.
You will find a list of recommended installation companies on our website.
Yes, the filter can also be installed horizontally.
The remaining capacity of the CO2 bottles is shown on the LED display of the cooler while you are tapping carbonated water. You will also see the value on the GROHE Watersystem app.

When the CO2 level has passed a certain threshold, you will receive a push notification on the app, reminding you to order new CO2 bottles. Moreover, the LED on the left handle of the tap flashes white 5 times if the capacities has fallen below 10%.
Latest when the CO2 bottle is completely empty (the water does not sparkle anymore), it is time to replace the CO2 bottle and reset the CO2 settings.
The remaining capacity of the filter is shown in the cooler display and on the GROHE Watersystem app. If the residual capacity is <10 %, the LED on the handle flashes and, depending on the settings, you receive a push notification telling you the filter needs to be replaced soon.
GROHE recommends that GROHE Watersystems are not left unused for a long period of time. If the GROHE filter systems are not used between two days and four weeks, the system must be flushed with at least four liters of water (depending on filter size. Please consulate the technical product information of the filter for further details). If the GROHE Blue system is not used for more than 4 weeks, it must be cleaned with the GROHE Blue Cleaning cartridge and the filter must be exchanged. During absence, the cooler should not be switched off for hygiene and contamination reasons!
GROHE Blue Professional consumes approx. 0.014 kWh of electricity in an hour. The values constitute an average over a 24-hour period with different drawing processes. The figure depends on a range of variables such as frequency of use and ambient conditions.
In addition to the cleaning of your GROHE Blue Professional watersystem with the GROHE cleaning cartridge twice a year, the supply and outlet air grilles must also be cleaned regularly. The hoses, the carbonate hardness setting and the aerator should also be checked regularly. The filter head must be replaced after five years. GROHE also offers maintenance contracts for companies. Please get in contact with GROHE customer service team for further support.
