5. For each of the following situations, do not attempt to repair the appliance on your own; return it to an auth
rized service facility for revision:
5.1 If the appliance falls into the water, DO NOT reach for it! First unplug it and then retrieve it. If electric
components of the appliance get wet, unplug the appliance immediately.
6. Do not operate this UV-C system if the cord or plug is damaged, if it is not operating properly after a fall or
other wise caused damage.
7. Never look at the UV lamp directly while it is operating, as it may cause eye injury, burns, or even blindness.
8. Lamps and quartz sleeves are extremely delicate. Care should be taken when handling or replacing these
components:
8.1 Wear cotton gloves when handling lamps or sleeves.
8.2 Hold bulbs by the ends only and never touch the glass with bare hands, since it would leave dirt which
would reduceit working life.
8.3 If any fingerprint is left, clean it with alcohol.
9. Allow the ultraviolet lamps to cool before handling.
10. Make sure that the nut, the washer and the O-Ring are correctly positioned, otherwise the quartz sleeves
could be expelled from their holder at speed and injure you.
11. Special safety warning must be taken into conside ration for the model Nano-Tech UV-C Ozone NT-UV87-TO:
11.1 The UV lamp generates ozone that emits a strong odour, even in very small quantities, and can be harmful
for eyes, nose and skin.
12. Check the system for any leakage. A proper installation and the correct position of the sealing rings are of
crucial importance.

P3 INTRODUCTION
2. INTRODUCTION
Ozone and UV-C are the two most efficient disinfection processes in water treatment. By mixing these two
concepts in one unique equipment you will keep your swimming pool water always fresh, crystal clear and to
tally disinfected, reducing the use of chlorine to a minimum.
2.1 HOW ULTRAVIOLET DISINFECTION WORK
Ultraviolet technology is a non-chemical approach to disinfection. In this method of disinfection, nothing is
added which makes this process simple, inexpensive and requires very low maintenance. UV-C light is becoming
increasingly favored by the pool industry as its ability to break down and remove chloramines, which will cause
eye, skin and nose irritation, and breathing difficulties.
UV-C light at a particular wavelength 253.7nm is a very powerful germicide. It deactivates the DNA of bacteria,
viruses and other pathogens and thus destroys their ability to multiply and cause disease.
UV dose of 30mJ/cmis sufficient for disinfection of the water and protection against 99.9% chlorine-resistant
micro organisms.
2.2 HOW OZONE DISINFECTION WORK
Emaux has developed a special model which combines the ozone and UV-C technology in one unique equipment
(see technical specifications for NT-UV87-TO).
Nano-Tech UV-C & Ozone (NT-UV87-TO model) contains a high intensity Ultraviolet lamp different from the
other UV models. This special lamp emits two separates wavelengths within the UV spectrum: 254nm and 185nm.
While the 254nm wave deactivates the DNA of bacteria, viruses and other pathogens, the 185 nm wave is
responsible for converting the oxygen contained in the quartz sleeve area into ozone.

5. INSTALLATION
Install the unit taking into consideration the access and space for servicing, and in a position where the lamp can
be taken out easily. It is important to choose your disinfection system according to the flow rate required for the
installation. If water passes through the unit too fast, the exposure time required for its maximum efficiency will
be not enough. For this reason, the ultraviolet equipment selected for your pool should correspond to the
maximum flow rate of your filtration system(pumps).
We also recommend to install the unit in a by-pass.
5.1 PLUMBING INSTALLATION
WARNING:
It is recommended to use the same power source for UV-C system and the filtration pump
such that they can be power ON / OFF simultaneously to prevent no water flow for UV-C
lamp cooling inside the stainless steelcylinder.
This UV-C disinfection system comes with all internal components assembled and it is ready
to be installed. Only pipesconnections should be made before starting up the equipment.

P7 INSTALLATION
To achieve the correct installation, please follow the recommendations listed below:
1. Never install the UV-C system in an area exposed to full sunlight. This equipment must be in stalled in a dry
and ventilated area.
2. The UV-C system must be fitted in a vertical position, and leaving a minimum space of 30cm und neathand
1.5meters at the top of the equipment for servicing and replacing the lamp.
3. The UV-C system will need to be plumbed into the swimming pool / spa / water feature circuit, always after
the filter and before pH regulator or salt electrolysis system (if any).
4. If the filtration pump exceeds the maximum flow rate allowed for the UV-C system, a by-pass circuit will be
required.
5. Fit the UV-C system with the supplied clamps in a fixed position and hand-tighten the 3 part couplings. Neve
use a wrench, tongs or other tools to tighten synthetic parts.
6. Make the UV-C connections 1½”or 2” to the circuit pipes.
7. Activate the pump and check that there is not any leakage in the circuit.
5.2 TYPICAL INSTALLATION
This water circulation system flow from water pump from swimming pool skimmer to sand filter and position the
Nano Tech UV-C lamp or ozone disinfection unit after filter and before chlorinator.
Water pH or ORP probe should be mount in front of the Ozone generator and chemical dosing, such as acid or
chlorine, after the ozone UV-C unit.
WARNING:
For UV-C and Chlorinator put together as disinfection system, the UV-C should be place
before Chlorinator.
Nano Tech, UVC products are not recommended to be used in seawater or seawater-like
environments with high salt content, as the stainless steel body will be corroded and
leaked in long term operation.

VENTURI INSTALLATION GUIDE
Follow the instructionsprocedure below for installing the Nano-Tech UV Ozone System:
1. Fit the manometer (A) onto the Venturicircuit using Teflon tape. Hand-tighten the manometer.
2. Insert (B) into the outlet (C), make sure that the threaded nut (D) is asthe following image displays :
3. Screw the female hose fitting (E) onto the male thread of the Venturi circuit. The other end of the hose must
be fitted into the elbow adapter, on the top of the system (F). There is a Non-Return valve (K) between (E) and
(F) which is a one direction valve to prevent air go backto the UV lamp Ozone generator.
4. Reverse the Non Return Valve will not inject Ozone to the Venturi systemand
5. Joint the 3parts(B), (D) and (L), so that the Venturicircuit and the UV systemare firmly assembled.
6. Afterwards, choose at suitable place to install the assembled system, if and when it follows the order
accoring to Section 3Typical Installation.
7. Fit the UV-C reactor with the supplied clips (H) and ensure that the 3-part couplings (B) (D) (L) are still
solilytighten. Never use a wrench, clamps or other tools whatsoever to fix the reactor.
8. The power supply wire (I) has to be connected in a way that the UV system works as the same time as the
filtrtion pump does. If not, all the UV systemcould get overheated.
