measuring. (The high-pressure pump works, the inlet valve opens, the
outlet valve closes.)
1. When the low-pressure switch determines that the raw water pressure
is beneath the pre-set value, the water filtering system changes to the
lack of water programme, and a buzzer sounds.
2. Neither the TDS value is measured nor it is indicated. (The high-pres-
sure pump works, the inlet valve opens, the outlet valve closes.)
1. If after 12 successive hours there is not any water inside the system
tank yet, the system changes to the maintenance mode. In that case,
contact an expert.
2. Neither the TDS value is measured nor it is indicated. (The high-pres-
sure pump works, the inlet valve opens, the outlet valve closes.)
Error message
•
This error message means that the TDS value is higher than 100 ppm. The controller setting
limit is at 100 ppm precisely. If the value is beyond this limit, the controller cannot determine the
value any longer, and the OVA message is showed.
•
The normal value is between 10 and 20 ppm.
•
There are several alternatives that lead to this error:
1. When the system is reinstalled, water contaminations can cause a high TDS value to be
indicated. We recommend to thoroughly rinse the osmosis system. The TDS value should
normalize by rinsing the system.
2. Check if the RO membrane has been correctly installed. It may lack or have been incorrectly
set into the housing. Thus, the water cannot be purified, and this leads to a high TDS value.
3. If the RO membrane is newly set in, you have to repeat the rinsing for otherwise the TDS
value can become too high.
4. The TDS controller may be dirty. Check the controller condition and clean it if necessary.
