Page 4: General Principles
2. General Principles The UV 80 IT SERIES sterilizers have been planned specially for destroying harmful bacteria and viruses present in your water. Their working is based on a physical principle which is a warrant of security: the output of ultra-violet irradiation. - Page 5 Attention: Working on live equipment is forbidden. INFORMATION TO USERS pursuant to art. 14 of the 2012/19 / EU DIRECTIVE OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 4 July 2012 on waste electrical and electronic equipment (WEEE) The crossed bin symbol on the appliance or on its packaging indicates that the product at the end of its useful life must be collected separately and not disposed of together with other mixed urban waste.
- Page 6 INSTALLATION GUIDANCE The reactor control panel utilises air cooling. The following guidelines must be adhered to when locating the unit. The reactor and control panel must not be located in a position where the ambient air temperature exceeds 40ºC. The reactor and control panel must not be located adjacent to other equipment that directly emit heat The reactor and control panel must not be located adjacent any chemical equipment that is likely to emit fumes.

Page 13: The Uv Chamber Installation
5. The UV Chamber Installation 5.1. Assembling of the UV chamber ● Unscrew the s/s sleeve bolts (A) from both sides by using the key supplied. ● Insert the quartz sleeves (B) by using the special bar supplied and the o-rings 38x4 (C) on both sides of the quartz sleeves. - Page 14 ● Screw again the s/s sleeve bolts on both sides of the UV chamber, and carry out the hydraulic test, verifying that the o-rings are watertight and that no water leaks outside the sleeve bolts or inside the quartz sleeves. ●...
- Page 15 ● Each lamps has 2 wires connected from the top to the bottom .Lamps must be inserted into the chamber with these wires in the opposite side to the sensor. To do this the two pins (signed with the red circle in the photo below) must be in the opposite side to the sensor.
- Page 16 ● Screw the Ø 1 ¼” ring nuts (F) on the s/s sleeve bolts. ● Mount the o-ring (I) (4112 type) on the measuring window (L) and screw this one on the Ø 1” bush welded in the middle part of the UV chamber.

To calculate the radiation factor % it is necessary that the lamps reach the steady state conditions. Delay time depends on lamps type and water temperature. We therefore advice to wait 30 min from the system start up.
- Page 30 ➢ Max temperature: settable threshold that defines the maximum acceptable temperature in the plant before shut off for safety. Important! In case of absence of flow the UV lamps can increase water temperature. This can damage lamps and UV system. If the temperature is higher than the threshold then the system will automatically turn off.
