Initial start-up and flushing of the membrane(s) WTS +0300130EN rel. 1.0 - 05.09.2022
8. INITIAL START-UP AND FLUSHING
OF THE MEMBRANE(S)
When the system is started for the first time and each time it is put into operation after a period of non-use, you must
remove the chemical maintenance solutions and/or standing water. If the system is not used for a longer period of time,
the membrane(s) must be replaced.
Risk of electrical shock!
Hazardous electrical voltage!
Follow safety instructions for work on live components
Notice: Do not use the water produced during this phase.
» Lead the hose for the permeate into the drain
» Make sure that the water supply is interrupted
» Close the valve to the expansion vessel
» Insert the membrane(s) and the 5µm prefilter into the pressure pipes
» Screw the covers of the pressure pipes tight
» Connect the unit to the power supply. The system goes into error mode due to lack of water
» Press

for two seconds, the display shows: "PASSWORD 0000".
» Enter the service-password (see additional information attached to the unit/ membrane)
» Confirm with

» Select menu item 14 (system test)
» Open the water supply (solenoid valve) to the unit
» Press é (Open the water inlet valve / activate the solenoid valve to flush the membrane(s)).
Let the system run for 10 minutes
» Press è (switch on the pump)
» Check the system for leaks
» Let the system run for another 10 minutes
» Press
è
(switch off the pump)
» Press é (this close the water inlet valve/ solenoid valve)
» Open the valve of the expansion vessel
» Press "ESC" twice (leaving the service level). The system starts to produce permeate
» Check whether the unit switches off after reaching the operating pressure (approx. 4 bar).
» Connect the permeate line to the expansion vessel
Notice
:
• At the start of each commissioning with the use of new membrane(s), the ROC unit produces a higher permeate quantity in
the first 2-4 hours, which is also accompanied by higher conductivity.
• Observe the note on the influencing factors (see chapter 4.1 mode of operation).
• The measured permeate conductivity value shown on the display of the controller will settle down to the actual value within
the first minutes.
8.1 System start-up after initial commissioning
Caution: Danger due to incorrect operation!
Commissioning may only be carried out by qualified personnel (electricians or specialists with equivalent training).
Step 1: Check mechanical integrity, water connection and cabling
» Check functionality of water and electrical installation.
» Check functionality of the pre-treatment system (if available).
Step 2: Check the feed water
» Check whether the feed water parameters are within the limits specified in chapter 4.3.
Step 3: Switch on the unit
» Switch on the main fuse
» Open the water supply shut-off tap
» Insert the power plug
Step 4: Observe device and check for leaks
» Let it run for 15 to 30 minutes
» If leaks occur, switch off the unit immediately.
Step 5: Remove leaks
» Locate and eliminate leaks
» Repeat leakage test
Step 6: Connecting the permeate line to the expansion tank
