General Principles and Safety Instructions
Information about UV irradiation:
MIOLEDhas been planned specially for destroying harmful bacteria and viruses present in your water.
Their working is based on a physical principle which is a warranty of security: the output of ultra-violet irradiation.
The UV light given out by special mercury vapours lamps (UV-C rays
λ
= 254nm) is highly germicidal because it
interacts with DNA and RNA, at a molecular level.
The deep bio-structural disorder caused by such irradiation interferes with the development and the ability of
reproduction of every kind of micro-organism, making it harmless.
Generally it is better to mount a pre-filter before the UV sterilizer, in this way the impurities of every nature and
consistence are kept.
This system comes to be necessary if we want to have a high degree of sterilization, infact the non-filtration and
removal of suspended particles in the water has, as a consequence, a decrease of the sterilizer's efficiency.
If the water to be treated contains sulphydric acid or more than 0.3 p.p.m. of iron or filtrable solids, once passed
through the sterilizer, it leaves a residual sediment on the quartz sleeve, which, therefore, must be periodically
cleaned (the frequency depends on the quantity and quality of water treated).
General directions:
According to the European rules EN 60204-1 (safety of the set-up off the electrical equipment-general rules) the
low tension electrical instruments (rule 2014/35/CE) must be connected to a current-tap provided with grounding.
Electrical Safety Instructions:
The lightning flash and arrowhead symbol is to alert the user to the presence of un-insulated
"DANGEROUS VOLTAGE” within the enclosure. The equipment may only be opened if main supply
is isolated. The main supply must not be restored as long as the equipment is open. This applies to
both the electrical panel and the UV reactor vessel.
WARNING
: Working on live equipment is forbidden.
