Initial Washing:
After installation it is recommended to perform the initial washing of the unit and connected
R.O. system.
For this, for R.O. systems with tank:
■
■
close the tank valve;
■
■
open the inlet valve;
■
■
open the filtered water faucet;
■
■
plug the unit’s power cord into the electrical outlet;
■
■
wait for water to arrive at the faucet (it may take a while, water flow usually is not high,
water foam and air may be going out of the system);
■
■
wait 1-2 minutes for more or less steady (yet usually low) water flow from the faucet and
close the faucet;
■
■
wait for auto flush to complete (18 s);
■
■
repeat steps “open faucet – wait 1-2 minutes – close the faucet – wait for auto flush to
complete” at least 5 times;
■
■
after you finished with previous step close the faucet and open the tank valve;
■
■
wait for the tank to fill to full (until “ready” LED indicator lights up) then drain the tank
completely by opening the faucet;
■
■
you may repeat the tank full refill – tank drain once again;
■
■
after you close your faucet the tank will refill again, and your system is ready for use.
For direct flow R.O. system:
■
■
open the inlet valve;
■
■
open the filtered water faucet;
■
■
plug the unit’s power cord into the electrical outlet;
■
■
wait for water to arrive at the faucet (it may take a while, water foam and air may be going
out of the system);
■
■
wait 2 minutes for more or less steady water flow from the faucet and close the faucet;
■
■
wait for auto flush to complete (18 s);
■
■
repeat steps “open faucet – wait 2 minutes – close the faucet – wait for auto flush to
complete” 5-10 times;
■
■
after you finished with previous step close the faucet, and your system is ready for use.
Please note that after initial installation of the unit and/or R.O. machine or changing the
filters or membrane, air contained in the new dry system or filter may come out sometimes
producing foamy, white filtered water. Water may look white due to tiny air bubbles in it. If you
leave the water to stand for few minutes all bubbles will surface and eliminate. Such aerated
water is clean and safe. Gradually over the coming days all air inside your system will find
its way out. To make this process faster you may repeat the initial washing procedure until
you’re pleased with the result. Also note that if for some reason the water supply contains a
lot of dispersed air, your R.O. machine may start producing aerated water again. The unit’s
internal pipes and components never take air from outside as they are completely air and
water sealed and leak-free.
