How It Works:
After the install use your R.O. unit as you normally would.
If your tank is not full the pump box will turn on automatically
and quickly fill it up with filtered water. Then it will flush the
membrane and shut off automatically. If you open the faucet
and take some filtered water from the tank the pump will
turn on automatically to refill the tank again.
For direct flow systems, just open the filtered water
faucet. The pump will turn on automatically and will
produce filtered water in real time until you close the
faucet. At the end of each water production cycle the
membrane will be flushed for 18 seconds, and then the
system will shut off automatically.
LED Indicators:
■
■
No Source: there is no water in the inlet line or it’s pressure is less than 7.25 psi (0.05
MPa). Make sure the inlet tube is connected and not kinked, and the water inlet valve is
open.
■
■
Working: the pump is working and connected R.O.machine is producing the filtered water
for you. Either tank is not full yet or filtered water faucet is open. No action is required.
■
■
Ready: filtered water faucet is closed and tank (if installed) is full. The pump is off. No
action is required.
■
■
Flush: 18 s membrane flush is going. No action is required.
■
■
Reset: idling protection was triggered. The pump is off. To restore normal operation
power cycle the unit.
Pressure Switches:
The unit is equipped with low and high pressure switches. The low pressure switch shuts off
the pump when there is no inlet water or its pressure is too low. The high pressure switch
shuts off the pump when the filtered water faucet is turned off and tank is full (if installed) and
high back pressure of the filtered water line is built.
Pump:
The unit is equipped with the low voltage booster pump powered by the included transformer
for safe operation.
Precaution:
Please do not use the model X855 with R.O. units equipped with low-production membranes
of flow rating less than 150 GPD. Also, your membrane should be “true” thin film composite
R.O. membrane,
not nano-membrane. The latter is usually identified by word ‘Nano’ or ‘LP’ or
‘ULP’ in the membrane model description. ULP/Nano membranes may be damaged overtime
by powerful pump of X855. Consult your service provider for proper type of R.O. membrane.
Upgrade your membrane if necessary.
Model X845 can be used with both R.O. and ULP/Nano membranes of 50-100 GPD rating.
Neither model is suitable for ultra-filtration (UF) systems.
