Water Purification System Instruction Manual
6 / 11
The usage to keep high quality pure water:
(1). The Ultrapure water is easily polluted by surrounding environment. So getting fresh pure water is
suggested.
(2).
Keep source water tank from sunlight for microbe’s reproducing.
(3). When get high pure water, initial high pure water is suggested to drain to get steady pure water.
(4). Avoid air bubble when get pure water to reduce air pollution.
Attention: The microbe’s reproducing will reduce the life of filter cartridge when the machine does not
work for long time. So t
he machine’s work every 7-10days is necessary.

Microcomputer Controller
Panel
There are 6 key-press on the panel. As follows:
6 key-press from left to right:
“RO”
key-press: open or close RO water valve.
“MENU”
key-press: main menu, all the data of the system will be set in the menu.
“ ”
key-press: choose the 1000,100,or 10-bit of set data. chosen position will show anti-color status.
“ ”
key-press: adjust the data of chosen position(0-9circle)
“OK”
key-press: confirm the adjusted data and execute corresponding function.
“UP”
key-press: open or close Ultrapure water valve.
Remarks:
The initial code is “1000”. After pressing “MENU” key-press, “please in code” will appear. Inputting the
code “1000” through shiftin “ ” and “ ”, then entering the main menu.

(2). After 5 seconds, the system will check the state of inlet water source. No inlet water or low pressure of inlet
water, the system will warn (picture 2).If the state of inlet water source is ok, system will implement the
following program.
(3). Check the conductivity of inlet water. Compare with previously set down conductivity of alarm. Check
whether the current conductivity of inlet water exceeds the previously set down conductivity of alarm. If so,
display the current exceeded conductivity and warn (picture 3).
（
for the following “flush” program (picture 4),
press “OK” key-press is needful
）
If not, system will switch to “flush” program (picture 4).

(4).
Under “flush” state (picture 4), RO membrane will be flushed for 25 seconds. Meanwhile system checks
the state of inlet water. No inlet water or low pressure of inlet water, the system will warn (picture 2). When
