Use of the osmosis system

6. Description of use of the osmosis system

Depending on raw water quality and pre-treatment, the maximum permissible yield is ap-
prox. 60% (RO30G & C: at 15°C approx. 350l/h, at RO60S: approx. 710l/h.).
This is a fi xed setting and must not be changed!

In practice this means that the permeate output of the osmosis can deviate widely,
depending on the raw water temperature. Water temperatures in Germany generally
range between 8 - 10°C in winter and between 13 -17°C in summer.
Depending on the line arrangement in the building, these fi gures may also be corrected
upwards.

Use of the osmosis system

6.1. Switching off the system

•
Cut off the water supply (2) and wait until the system switches off.
Now cut off the water at the water line and remove the hose.
Remove the system from the power supply.
•
Now close the water outlet (9) and pull the hose off the pole.
•
Now open both water connections (2) & (9) again in order to depressurise the
line and allow the rest of the water to run out.
6.2. Maintenance and care
If the system is shut down for a prolonged period (7 days), it must be prepared for
storage to prevent contamination of the membrane.
It is recommended to have the system serviced 1x per year by an authorised dealer or
Unger.
6.2.1. Pre-fi lter
Prior to each start-up, visually check the degree of contamination of the pre-fi lter (3)
and replace, if necessary.

6.3. Anti-freeze protection

The system must be protected against frost. Minimum ambient temperature 5°C.
CAUTION
Never use any other chemicals, since all agents used must be tested for mem-
brane compatibility.
