Start-up:
Having connected the water system:
• Open the water supply slowly, making sure there is no leakage.
• Press the start button
• Open the tap and let water flow to bleed the air.
ATTENTION: Do not operate the machine without having opened the water supply first.
The pump can get damaged if run dry.
After operation, sanitise the system.
Carefully fill in the installation certificate and the maintenance table and affix the serial
number sticker from the sanitising agent packaging on the cap. Everything must be kept
with the system. Alternatively, preserve and manage data and records of intervention
using the RO-Check app. If the documentation is not filled in properly, the manufacturer
cannot be held in any way liable for the quality of the water treated and for the integrity
of the system.
Check and, as necessary, adjust pressure and fixed residue (see dedicated section).
Pump adjustment
The vessel is equipped with a pressure adjustment system. In the pressure testing
phase it is adjusted to 8 bar. The pressure can vary based on the actual conditions at the
installation site or based on system wear. After installation and during the maintenance
phase, check and adjust the pressure if necessary.
Procedure
Activate the system and check the pump pressure.
If calibration is necessary, proceed as follows:
• Unscrew the adjustment device to minimum pressure
• Screw in the adjustment device to slightly exceed the calibration pressure
• Work on the adjustment device to reach the calibration pressure
Mixer adjustment
The pump is equipped with a bypass system to adjust the fixed residue of the produced
adjustment, measure the pH, checking it has returned within the potability values.
Permitted values:

water; the bypass is completely tightened in the test phase. After
installation and in the maintenance phase, check and adjust the
bypass if necessary.
The fixed residue can be estimated with the TDS meter or
conductivity meter. Use the bypass system knob until you reach
the desired value.
Fixed residue that is too low could influence the pH. After
