Step 1: Tapping into cold water supply
There are a number of ways to connect the system to the mains water supply. Provided RO
systems will be equipped with 3/8” Brass Water Feeder. We use special brass water feeders
which provide a check valve according to DIN 1988. This prevents water from returning back
into the mains system which in Germany is required according to law.
CAUTION: The water supply to your RO unit MUST be from a COLD water
line. Hot water will severely damage your RO system.
Important:
The following installation manual is a recommendation for a typical mounting. Local
regulations for installation and standards for construction may contain different or additional
requirements. The plumber that does the installation is responsible for the compliance with
effective regulations.
Installation
1. Locate the cold water shut off valve under your sink (if the feeder is installed after this
valve) and turn it off.
2. Open cold water faucet to release pressure and make sure there is no water running.
3. Mount the brass water feeder (3/8'') between cold water shut off valve and cold water tube
to your standard faucet or to 3in1-faucet (especially made for RO units).
4. Unscrew flexible hose from cold water shut off valve.
5. Connect brass water feeder to cold water shut off valve.
6. Connect brass water feeder to flexible hose (cold water supply to faucet).
7. Tighten all connections. You don’t need to seal the connections as there is a rubber o-ring
at the end of the connection which seals it.
8. Push white tube (connection to RO unit) into JG type push-in fitting (see page 13) and
secure connection by inserting safety clip.
9. Turn the ball valve handle to close position (push grey lever at right angle to white tube),
open main or cold water shut off valve and check for any leakages.
We have enclosed the most common thread dimension used in Germany. If you
need a different thread dimension such as ½“ or ¾“ for your connection, please let us
know or you can buy an adapter in a construction market or at a sanitary retailer.
Important: The brass water feeder according to DIN 1988 is only availabe in thread
sizes 3/8“- or 1/2“. The size 3/4“ is only available without check valve.
