 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 the machine’s work every 7-10days is necessary.

10. Trouble Diagnosis

Ⅰ. Motor failure

A. Check whether the pressure of the tap water is high enough. When pressure is low, low pressure switch

will cut off power.
B. Check whether the high pressure switch or water level controllor is normal.
C. Check whether special PP filter or Active carbon is blocked which cause the overload of the motor.
D. Check whether control panel is OK (for full automatic model)

Ⅱ. Pump Leaking

A. Check whether special PP filter or Active carbon is blocked which cause the overload of the motor.

Then high pressure lead to leaking. Resolution: change special PP filter or Active carbon and repair the

pump.
B. The expiring of the pump rubber membrane or the dirt will cause leaking too. Please repair the pump

and pay attention to checking the LV. 1-special PP cotton.
C. The block of the waste water proportion vessel will cause the block of the reverse membrane. Then

pressure increase. Water with high pressure will break the pump rubber membrane, then causes

leaking. Change relative components will be ok.

Water Purification System Instruction Manual

11 / 11

Ⅲ. Motor working but no water

RO membrane is blocked or pump’s pressure lost. For the former, change the RO membrane; For the later,
check whether expiring of pump is caused by long time overload or blocking of the cartridge. Repair motor.

Ⅳ.Motor works ever and again

The motor works ever and again. It is the reason that low pressure or blocking of LV.1cartridge. Please
install a booster pump or replace LV.1cartridge.

Ⅴ.The pressure tank is full of water, but pure water can not flow out

A. Air in the pressure tank leaks. Please fill it with 7psi air and check whether air leaks. If air can not be

put into tank, change the pressure tank..

B. Backset active carbon is blocked. Please replace it with a new one.

Ⅵ. Power is off, but RO water does not stop flowing.

A. Check the four-side water circuit breaker, and replace it if it goes wrong.
B. Pressure of inlet water is higher then the set pressure of high pressure switch. Please regulate the

pressure of inlet water no more then 2kg/cm2.

Ⅶ. The machine can not stop running when pressure tank is full of water or it runs at once after one stop.

A. High pressure switch or liquid level controller goes wrong. Repair it if it works after repairing, otherwise,

replace it with a new one.

B. Non-return valve leaks pressure so that it can not close. Replace it please.
