1.-SAFETY WARNINGS
IMPORTANT: The instruction manual you are holding includes essential information on the safety measures to be implemented
for installation and start-up. Therefore, the installer as well as the user must read the instructions before beginning installation
and start-up. Keep this manual for future reference.
The following safety instructions have to be taken into consideration when installing or using the Ultraviolet Unit:The unit is for swimming
pool and Spas only. Do not use this device for potable water sanitation (drinking water).The system must be connected only to a supply
circuit that is protected by a Ground Fault Circuit Interrupter (GFCI), otherwise could result in electrical shock causing serious bodily
injuries, including death.
- Disconnect all power supplies during installation.
- Do not operate the Ultraviolet unit if the power supply lead is damaged.
- Replace damaged cords immediately.
- To avoid possible electrical shock, special care should be taken keeping all connections dry and off the ground. Do not touch the
plug with wet hands.
- For each of the following situations, do not attempt repairs yourself; return the unit to an authorized service facility for servicing:
·If the appliance falls into the water, DO NOT reach for it! First unplug it and then retrieve it. If electrical components of the
appliance get wet, unplug the appliance immediately.
·Do not operate any unit if it has a damaged cord or plug, or if it is malfunctioning of if it is dropped or damaged in any manner.
- Never view the ultraviolet lamp directly while operating as it could cause eyes injures, burns or even blindness.
- Lamps and quartz sleeves are extremely delicate. Care should be taken when handling or replacing these components:
·Wear cotton gloves when handling lamps or sleeves.
·Hold bulbs by the ends only and never touch the glass with bare hands, since it would leave dirt which would reduce it working life.
·If any fingerprint, clean it with alcohol.
- Allow the ultraviolet lamps to cool before handling.
- Check that the nut, washer and O'ring are correctly positioned, otherwise the quartz sleeves could be expelled from their holder at
speed and injure you.
Special safety warning must be taken into consideration for the mode ATEC UV- C Ozone:
- The UV lamp generates ozone that emits a strong odor, even in very small quantities, and can be harmful for eyes, nose and skin.
- Check the system for any leakage. A proper installation and the correct position of the sealing rings are of crucial importance.
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 totally disinfected, reducing the
use of chlorine to a minimum.
2-1.-HOW DOES THE UV 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 pow erful germicide. It deactivates the DNA of bacteria, viruses and
other pathogens and thus destroys their ability to multiply and cause disease. (Fig 1)

UV dose of 30mJ/cm , is sufficient for disinfection of the water and protection against 99.9% chlorine-resistant
microorganisms.
