QuaRO PUR ECO and QuaRO PLUS ECO
The RO units QuaRO PUR ECO and QuaRO PLUS ECO are equipped with a
“permeate pump”.
A reverse osmosis system such as QuaRO Pur/Power utilizes an automatic shut-off
valve (ASO) that stops the RO system from producing water when the storage tank
reaches 50%-67% of the incoming water pressure. As the storage tank gets close to
being full, the system is sending more water down the drain due to the increasing
back pressure from the storage tank.
When a
permeate pump
is installed, the RO membrane is isolated from this back
pressure and allows the RO membrane to operate with up to 85% of the incoming
water pressure, even when the storage tank is nearly full. This dramatically improves
the efficiency of the membrane and overall quality of your water, as well as
increasing the pressure and related volume of stored water in the storage tank.
When you install your system, make sure the in and out ports are oriented
vertically one above another. The brine IN and permeate IN ports must be
located down and the brine OUT and permeate OUT ports must be located at
the top. If you don’t install the permeate pump as described the permeate pump/your
RO system can’t work properly.
How to test the proper function:
Open cold water supply. The RO unit should produce filtered water. If you close the
storage tank valve, you should see that a small amount of water pours out of the
faucet and then out of the drain water tube – continuously one after another. The
permeate pumpe will click regularly while the water filter system is producing water.
This sound is normal. If you hear this sound your permeate pump is working properly.
