Figure 5

6.2 Getting Corresponding Pure Water

There are 2 kinds of dispensing models to get pure water, instant dispense and quantified dispense.

In the main interface, touch the icon "Dispense-pure water" or "Dispense-ultrapure water" to switch to the interface of "Dispense-pure water (2-stage RO water)" or "Dispense of ultrapure water (DI water)".

Instant dispense

In the interface of "Dispense- pure/ultrapure water", touch the icon "Instant" to switch to the interface of "Instant dispensing-pure/ultrapure water", then pure/ultrapure water goes out. When dispensing water is ok, touch the icon "Stop" to stop pure/ultrapure water going out.

Quantified dispense

In the interface of "Dispense- pure/ultrapure water", touch the icon "Quantified" to switch to the interface of "Setting-quantified dispense". Input the amount and confirm it, at last touch the icon "Dispense" to switch to the interface of "Quantified dispense-pure/ultrapure water". Touch the icon "Start" to get pure/ultra-pure water, touch the icon "Pause" to pause, and touch the icon "Pause" again to regain water. Touch the icon "Cancel" to stop getting water.

When the dispensing water process is ok, touch the icon "Back" to switch to the main interface.

ATTENTION

The value of quantified dispensing water will be more accurate, when the pure water in the external pressure tank is enough.

6.3 Standby

When DI water is not for use, the system will be in standby state. The system still produces RO water to store in the water tank (optional). Until the tank is full, the system will automatically stop. The system will begin to produce pure water again when any pure water is used.

6.4 Releasing internal air of terminal filter (Optional)

Unscrew the rounded nut, which is on top of the terminal filter, open the valve of DI water (Additional DI water outlet, which is on the back of the machine, should be closed at this time, or all the DI water will go out from this outlet).

When DI water goes out, the internal air of the terminal filter will be released. Until the terminal filter is nearly full of DI water, then tighten the rounded nut.

ATTENTION

If the internal air of the terminal filter is not released,pure water can not go through the terminal filter for air resistance, then the system will stop working for high pressure.

6.5 Shutdown

Turn off the tap water valve and turn off the power switch. Then it is ok.

ATTENTION

Make sure that the source water and power source is not connected, when the system is not in the use state for a long time (for example, off duty).

6.6 The Usage to Keep High Quality Pure Water

1. The pure water is easily polluted by the surrounding environment. So getting fresh pure water is suggested.

2. Keep the water tank from sunlight for microbes reproducing.

3. When get high pure water, initial high pure water is suggested to drain to get steady pure water.

4. Avoid air bubbles when getting pure water to reduce air pollution.

ATTENTION

The microbe's reproduction will reduce the life of the cartridge, when the machine does not work for a long time. So the machine's work every 7-10days is necessary.

6.7 Water leakage protector

This series of pure water machines is equipped with a water leakage protection system. Once water leakage is detected in the pure water system, the protection system will automatically close the ball valve, cut off the water source, and constantly sound and light an alarm, prompting the user to check in time and press the button to restore after eliminating water leakage.

When the water leakage problem is removed, remove the water leakage sensor switch and wipe the water stains on it. Otherwise, it will cause misjudgment, and the water leakage problem is not removed and the alarm will be kept.

8. Water Quality Test

The system has 3 monitor sensors of water quality measuring.

The first, monitors source water's quality (Source water). Measure unit: Conductivity (us/cm)

The second, monitors 2-stage RO water's quality (2-stage RO water). Measure unit: Conductivity (us/cm)

The third, Resist, monitors DI water's quality (DI water). Measure unit: Resistivity (MΩ.cm)

REMARKS

Under normal conditions, new RO membrane's desalination rate is above 97%. It means that TDS of RO water should be less than TDS of inlet tap waterx5%.

If TDS of RO water > TDS of inlet tap waterx10%, it means that RO membrane's desalination can't meet the minimum requirements. RO membrane should be replaced at once.

Conversion relations between TDS and conductivity rate(μs/cm): If TDS<50ppm, conductivity rate (μs/cm) ≈TDSx2

If TDS>200ppm, conductivity rate (μs/cm) ≈TDSx(1.5~1.7).
