(1) Filtration indication:
during the filtration process, the water drop-shaped drips from top to bottom, the ripple spreads
out from inside to outside.
(2) Flushing indication:
after 40 minutes filtration, it enters into flushing process. The icon shows that:
flushing 1: pressure tank storing water;
flushing 2: pressure tank backwashing;
flushing 3: forward washing.
(3) Power button:
press this button to turn ON/OFF the device operation, when the device is in the stop condition,
all valves are closed (adopted electric valves).
(4) Time code:
shows the time of each stage (water producing, water storing, back washing, forward washing). If
the time code is not flashing, press (power button) to enter into the next stage time setting.
After time setting in any stage, press (mandatory flushing button) for 2 seconds can save the
set time, the new set time will take effect on the next startup.
(5) Mandatory flushing button:
when press this button, the device will execute once flushing process.
(6) Electricity lost detection function:
for water safety guarantee, if there is no city electricity, all valves will be closed automatically.

7. Time Setting
Step 1:
power on, in the standby status, press and hold (mandatory flushing button), then press (power
button), 2 seconds later (time code) lights up.
Step 2:
release (power button) and (mandatory flushing button), (time code) flashing, press (power
button) can modify the flashing digital.
Step 3:
after setting finished, press (mandatory flushing button) can switch the flashing digital.
Time modification:
The time of water producing, water storing,
back washing, forward washing can be
modified.
Time modification is divided into five stages:
water producing 1, water producing 2,
flushing 1, flushing 2, flushing 3.
The corresponding time: water producing
time (0~99hour), water producing time
(0~59min), water storing time (0~99sec),
back washing time (0~99sec), forward
washing time (0~99sec).
The corresponding status shown on the panel:
“filtration indication + number 1” lights up,
“filtration indication + number 2” lights up,
“flushing indication + number 1” lights up,
“flushing indication + number 2” lights up,
“flushing indication + number 3” lights up.

8.Power Connection
a. Power supply is low voltage DC (12V), the interface is socket type at the top.
b. Control element: three low voltage reversing electrically operated valves.
c. Connection principle:
1. SW and OPEN short sub, electrically operated valve open, after putting in place and maintain.
2. SW and CLOSE short sub, electrically operated valve close, after putting in place and maintain.
9.Working Process
1. Filtration:
Under the action of water pressure, raw water through DD1 and enters into UF filters; DD2 is closed
at the moment. DD3 opens, filtered water comes out.
2. Flushing:
a) DD1 opens, DD2, DD3 are closed, pressure tank starts to store water (20 seconds).
b) After water storing finished, DD1, DD3 are closed, DD2 opens, water stored in the pressure tank
starts to back wash UF filters, the flushing water comes out from the discharge outlet (20 seconds).
c) After back washing finished, DD1 opens, raw water forward washes UF filters and comes out from
the discharge outlet (20 seconds).
