6. Startup & Commissioning
Before you start:
• Take the 10 mm hose from RO permeate and disconnect it at the tank and put it to the drain.
•
Slowly turn on water supply to avoid pressure boost.
Power on:
• Connect power supply.
• System will startup and open water inlet, permeate production starts.
• Let the system run in this position until all air is out of the membrane.
Adjust drain %:
• Measure and note the permeate water ow l/h.
• Measure and note the drain water ow l/h.
• Adjust the 1/4” drain needle valve until the required drain ow is reached:
min. 30 % with softener. - Use formula ”with softener” to calculate.
min. 50 % without softener. - Use formula ”without softener” to calculate.
• Lock the valve with the designated nut.
• Disconnect power supply to stop the water ow.
• Reconnect the 10 mm permate hoses to the tank.

• Messure µS/cm.
• Normal limit 5-30 µS/cm, in clean water areas µS/cm can drop to 0.
• This can have a negative eect on some processes.
End with:
• Check that the water inlet pressure during RO production is min. 3 bar .
• Check for leaks.
• Fill out AirtecCare checklist.

• Take the 3/4” hose going to the consumer and put it to drain.
• Turn on fuse F2 6A, PM2 default starts in alarm - press reset.
• Wait until the 3/4” hose has a clean water ow without air, the pump should now be producing
water pressure.
• Turn o fuse F2.
• Reconnect the consumer hose.
• Turn on fuse F2.
