A、Overview of Ultraviolet Water Sterilizer：
The ultraviolet ray is a kind of invisible light wave to the naked eyes. It exists on
the outside of the purple ray on the spectra. So it is called ultraviolet ray. The
ultraviolet ray is subdivided into wave band A (UVA), wave band B (UVB), and
wave band C (UVC).The wave length of UVC is between 100nm to 280nm, and
the most effective germicidal wave band is 253.7nm.
1. Principles：Put the water in the exposure of UVC spectrum at the wave peak of
254nm for some time. The nucleic acid, deoxyribonucleic acid (DNA) and
ribonucleic acid (RNA) of microorganisms will absorb UV rays and be damaged
by the rays. So the water is sterilized. UV rays have a certain effect on protein
and other life forms too.
2. Sterilization range: UV water sterilizer can effectively kill the algae, fungi,
bacteria, richettsia and virus to purify the water.
3. Merits of the sterilizer: UV sterilizer uses a completely physical way to sterilize
water, which makes it easier to operate and more efficient without second
pollution, corrosion, pollution and residue. It has broad spectrum and is quite
convenient for maintenance.
4. Application range: UV water sterilizer can be mounted as a pre-posed or rear
sterilization equipment in domestic or industry water purification equipment. It
can be applied to various kinds of water sterilization.
B、Structure Diagram of Ultraviolet Water Sterilizer：
1. Structure diagram of economical UV-C water sterilizer：Each model of the
sterilizer cylinder adopts 304 or 316 stainless steel which is non-toxic, no- rust,
no metal ion pollution and meets food hygiene requirements.

2. UV lamp wiring diagram: adopt European Philips UV lamp which is of high

quality and long service life.

3. Replacement diagram of safe lamp holder：

You need to screw the nut of the safe lamp holder clockwise to the suitable place and
then you’ll hear the sound of the switch. If you don’t hear the sound, it means that
the nut isn’t screwed to the suitable place. In that case, you can choose to switch off
the holder a little bit anticlockwise and adjust the angle between the thread and the
nut to make sure that the thread of the safe holder can be easily screwed into the nut.
Note: Please don’t screw the lamp holder too much.

5. Monitor reset
After the lamp is replaced, reset the monitor. (no need to reset after clean the
sleeve) The specific way is as below:
First keep lamp working for over 1 hour. Press the “SET” key for over 5 seconds.
The UV intensity will be back to 100% and time back to “0000”. Reset is
finished. Monitor enters into normal operating status.
I、Disassembly Diagram of Ballast XH-3 and XH-6:
If ballast fails please disassemble the circuit board according to the below diagram
or directly change the ballast. Please turn off the power before disassembly.
Disassembly steps: disassemble the front wiring row, use a screwdriver to remove
two retaining screws of the fixed slider. Then take out the fixed slider and pull out
the ballast conforming to its own direction. Finally install the new ballast
according to the disassembly steps.

PS: The first ballast in the UV sterilizer control box is the backup ballast. It can be
used immediately in case the other ballasts fail. Just take down the failed ballast
from the wiring row and plug the backup one.

C、Mounting steps and matters need attention
1. Before mounting, please refer to the “Structure diagram of ultraviolet water
sterilizer” to learn about sterilizer components. Mounting the sterilizer
according to the “mounting steps and matters need attention” in user manual.
2. If you choose vertical mounting, make sure that water inlet mounted at a lower
level while outlet at a higher level to lower down the flow speed to increase
radiation.
3. If water current exceeds rated flow please fix current-limiting or
pressure-limiting device.
4. If water pressure is over 5kg/7kg, please fix a check valve in the inlet/outlet in
order to protect the quartz sleeve.
5. If the normally closed solenoid valve is needed, please fix it in the inlet.
6. Please add a no fuse breaker when mounting a big horizontal type.
7. Please fix the sterilizer at a certain position by retaining clip, retaining nuts or
other fixing device in order to prevent it from dropping because of the shake
caused by water and damaging the internal fragile parts.
8. Connect lamp according to “UV lamp wiring diagram”. Four-core lamp holder
and lamp connector wires are butted according to number and connected with
both ends of lamp then get through perforation nut and covered with dust cap.
9. Connect up the inlet/outlet to related water pipes and fill water to test leakage.
Use visual inspection to check every connector whether there is a leak. If there is
no leakage please insert the plug and turn on the power.
10. Ballast can automatically inspect whether the UV lamp is well-connected. If
damaged or the four-core lamp holder or connector wires are not well-connected,
ballast will give out “BB” sound. Red light will turn on.
11. When the power of horizontal UV-C sterilizer is on, UV radiation intensity
monitor (optional) or timer starts to monitor the radiation intensity or timing too.

D、Notices for Maintenance

1. For safety, please put on goggles and power off before replacing the UV lamp or
cleaning the quartz sleeve! Do not replace it with naked eyes or power on! It
will damage the ballast, too.
2. When replacing UV lamps, please don’t pull the lamp connector wires forcibly.
Please press the big terminal of wires and pull out the lamp slowly. Do not pull
out the big terminal of wires or wiring port of four-core lamp holder forcibly.
3. UVC has a strong ability of sterilization. Please do not look at the UV lamp
with naked eyes directly. The radiation will cause you conjunctivitis.
4. Ultraviolet water sterilizer ≠ water filter. It is unable to eliminate the bad taste,
bad smell, biological materials, kinds of chemicals, silt, heavy metal and other
kinds of impurities or lower the water turbidity which will decrease sterilizer
germicidal ability. So it is necessary to install a pre-posed filter to ensure that
the sterilizer can achieve the best disinfection effect.
5. Take the quartz sleeve out every 3-6 months to check whether there is scaling on
surface. This is helpful to predicate when to clean the sleeve surface again.
3
E、Cleaning and Assembling Steps
Use the neutral soap or citric acid to clean the scaling on the sleeve surface.
1. After cleaning, please wipe the sleeve with alcohol and then fix it inside the pipe.
2. Cleaning steps ：turn off the powertake out the lamploose the nuts of
both endstake out the quartz sleeve (keep silicone rings) clean the sleeve
3. Assemble steps：fix the silicone ring on the no-hole terminal of quartz sleeve and
put the sleeve straight in steel pipe tighten the no-hole nut fix the silicone ring
on the open terminal of quartz sleeve tighten the perforation nut to make sure the
nuts on the two terminals are tight enough with no leakage fill water to test
leakage connect the two ends of the lamp with four-core lamp holder and lamp
connector wires then put them into the sleeve turn on the power, the green
working light turns on.

3. UV lamp manufacturer suggests lamp should be replaced after being used for
about 8000 hours to ensure its designed germicidal effect.
4. Once a UV lamp is replaced, the timer needs to be retimed. Press “SET” key for
5-10 seconds. Timer will become zero automatically and start timing again.
5. If you need to reset the timer. First press the shift key for about 5-10 seconds.
The panel will show “29-1”. Then press the up key to set the number to “22-1”.
About 10 seconds later, the automatic reset is done. Both of the lines will show
“0000”. Now press the shift key until the above line shows “9999” and below
shows “5959”. Finally use the shift key and up key to set the above line to
“8000” and the below line to “0000”. Then release both of the keys, 10 seconds
later the timer starts to work again automatically.

3. At the very beginning, the UV intensity is low. It is a normal phenomenon if
monitor gives out alarm. A few minutes later it will resume normal operation.
4. Fault mode：
a. When the UV intensity is lower than 80% of the initial value, the alarm
indicator turns on and the panel shows fault mode E-01 like diagram 2, the UV
lamp needs to be replaced or the quartz sleeve needs to be cleaned.
b. When a UV lamp has been used for over 8000 hours, the alarm light turns on
and the panel shows fault mode E-02 like diagram3. Replace the UV lamp.
