frequently asked questions

Installation

What do I need to consider when installing Grohe Blue?

The cooler requires sufficient air ventilation and required a warm air exhaust outlet to the bottom of the cabinet. A gauge for the cut-out is included in every product set.

Where do I get the water hardness from?

The carbonate hardness (relevant for the GROHE Blue S-, M- and L-size filter) can be measured with the included test stripe while the total water hardness (relevant for the GROHE Blue Mg+ filter) can easily be requested at your local water supplier

Maintenance

When do I need to change the Filter?

The filter must be changed after 12 months or when capacity is exhausted. The LED in the fitting’s left handle indicates the filter capacity: Flashing blue/tourquoise/green light - less than 20l filter capacity -> order a filter cartridge. Rapidly flashing orange light -> filter cartridge must be changed.

How do I change the filter?

The filter can be easily screwed in and out. The water supply does not need to be turned off.

How can I dispose the filter?

The filter can be disposed of as normal plastics.

When do I need to change the CO2 Bottle?

When the CO2 bottle is empty the Ondus app will inform you with a push notification and the affected system will be ranked ahead of all others in your control desk. Moreover the LED LED in the fitting’s left handle will start to flash in white.

How do I change the CO2 bottle?

For the 425 gr bottle, release the pressure valve including adapter from the bottle and connect new bottle. For the 2kg bottle, close the bottle, release the pressure valve including adapter from the bottle and connect new bottle and then open it.

What are the capacities of the GROHE CO2 bottles?

  • 425g bottle = 55 Liters of full sparkling water
  • 2kg bottle = 350 liters of full sparkling water

What happens if I do not use Grohe Blue for an extended period of time?

GROHE recommends not leaving the filter system out of service for extended periods of time. If the GROHE Blue filter system is not used for a few days, the filter system must be rinsed with at least four liters of water. If you leave the system unused for more than four weeks then the system has to be cleaned with the GROHE Blue® Bio-Clean cleaning liquid 40 434 001 and the filter must be replaced.

Alternatively you can activate the auto-flush function via the Ondus app to have the system flushed automatically once a week.

How do I clean/desinfect the system?

Disconnect the filter and CO2 bottle from the system. Disinfect your hands and the cleaning adapter by using the sprayhead of the cleaning cartridge. Then attach the cleaning adapter to the filter holder, screw the cleaning cartridge into the preassambled adapter and activate the automatic cleaning mode via the Ondus app or cooler display.

?The cleaning will take 20 minutes and in the process the LED in the faucet's left handle will light up purple. Once the cleaning is finished the purple light will dissapear. The cleaning catridge and adapter can be removed and the CO2 bottle and a new filter can be connected again.
