Reverse osmosis system

Reverse Osmosis (RO) system

– Brewing water for filter coffee

Achieve ultimate control over your brewing water with this highly efficient reverse osmosis system. With three-stage filtration, the system effectively removes lime, chlorine, heavy metals, pesticides and other impurities, ensuring clean and neutral water, perfect for creating the exact water profile your brew requires.

Features:

• 3-stage filtration (pre-filter, activated carbon filter and RO membrane)
• Effective even at low water pressure (from 2.1 bar)
• Produces up to 12 litres of clean water per hour at 3 bar and 12°C
• Easy installation directly on existing tap
• Ideal for all types of beer brewing and precise water adjustment

Use the RO water as a starting point for precise adjustment of the mineral profile for manual brewing.

Content:

• 1 tap adapter
• 1 inline sediment filter 5µ

• Osmosis membrane 75 GPD ULP - Ultra Low Pressure
• 1 diaphragm housing and collet
• A straight fitting with gasket and 1/2" internal pipe thread
• 3 metre 1/4" plastic hose, 1 metre white, red and blue
• 450ml restrictor
• Brackets and screws for wall mounting

Extended User Guide

Installation

1. Location:
   • Find a suitable location close to water connection and drainage.
   • Make sure the system is stable and upright.
2. Assembly:
   • Remove the blue lock and hose to the RO membrane housing
   • Install the RO membrane as shown in the picture and reinstall the hose.
   • Connect the water hose (white) to the system and the tap with the included adapter or tap connector.
   • Connect the waste water hose (red) and lead it to the drain or tank for garden watering etc.
   • Connect the RO water out hose (blue)
   • Replace all the little blue fuses.
   • The tap is used to adjust the ratio between wastewater and RO water.
3. Density test:
   • Slowly open the tap and check that all connections are tight.
   • Fix any leaks immediately.

Operation and use

1. Start:
   • Allow the system to run for at least 15 minutes on first use to clean the system.
   • Adjust the tap to approx. 1/3 RO water
   • If you have a TDS meter, you can fine-tune the ratio of RO to waste water for optimal water utilisation.
   • Now collect the first RO water.
2. Daily use:
   • Leave the system running and collect the purified water in a clean, preferably sterile container.
   • The water is now ready to use in your beer brewing.
3. Mineral customisation:
   • Customise the mineral profile as needed with desired salts (e.g. calcium chloride, calcium sulphate, calcium carbonate or magnesium sulphate). See more under Water treatment

Maintenance

• Filter replacement:
  • Sediment filter and carbon filter should be changed every 6-12 months depending on usage and water quality.
  • The RO membrane is typically replaced every 2-3 years or when efficiency drops noticeably.
• Regular cleaning:
  • Flush the system with clean water if it has not been used for an extended period of time.
  • Store the system in a dry place when not in use to avoid bacterial growth.

Troubleshooting

• Low water production:
  • Check the water pressure and temperature (ideally 2.1 bar and 12-20°C).
  • Check filters and membrane for clogging and replace if necessary.
• Leaky system:
  • Check all fittings and gaskets and tighten or replace if necessary.

Following this extended guide will ensure optimal performance, longevity and the best quality of your brewing water.
