GENERAL INFORMATION
An
Ultra Violet Disinfection System
is a versatile unit designed to kill waterborne bacteria using the proven
method of exposure to ultra violet light.
The unit is made from a tubular quartz sleeve in which a UV lamp is inserted. Both components are housed in a
stainless steel outer chamber called a reactor. Water is disinfected as it passes through the reactor and is exposed
to a high intensive UV light that penetrates and deactivates bacterial cells.
The outer of bacteria and viruses differ in thickness and it is this thickness of skin which determines the amount of
UV light exposure to prevent their reproduction, rendering them dead.
UV systems should be installed with pre-filtration down to 5 micron. This prevents an effect called shadowing
where micro-organisms could hide behind particles in the water.
LOCATION
The steriliser should be mounted in a location
allowing sufficient room at the end of the unit to
withdraw the lamp and quartz sleeve. If this is not
possible use a flexible hose set allowing the chamber
to be unclipped from it’s mounting bracket(s) for
service and lamp change. Where possible the unit
should be installed to treat all the water as it enters
the system. If treated water is to be stored, the
storage tank should be fitted with a close fitting lid
and the overflow protected with a fly screen (Water
by-law 30). Tanks should only hold sufficient water for
a few hours use.
LAMP LIFE
The lamp will continue to emit sufficient ultra violet
for efficient operation of the unit for a period of
4,000 hours. The lamp must always be replaced at
this interval although a safer recommendation
usage period is one year or 2,000 hours. Failure to
change the lamp will result in insufficient UV
dosage for bacteria killing.
ELECTRICAL INSTALLATION
All metal components should be earth bonded.
Ensure the earth wire from the power supply is
connected to the earth point located at the one end
of the chamber. To avoid possible electric shock,
special care should be taken since water is present
near electrical equipment.
PLUMBING INSTALLATION
Although the chamber can be mounted at any
angle, the outlet connection should always be
uppermost to prevent airlocks in the chamber - the
ideal installation is vertical. Good quality pre
filtration is essential for correct operation. Replace
filters as required and always fit new elements,
never wash a dirty filter.
QUARTZ SLEEVE
The quartz sleeve should be checked and cleaned
periodically. When cleaning the quartz sleeve
ensure the unit is isolated from the electrical supply
and check the water supply is also turned off prior
to servicing.

UV DISINFECTION - OPERATING & MAINTENANCE
Never operate the unit if the lamp is outside the chamber.
Never stare at the light source.
Exposure to ultra violet light can cause conjunctivitis and erythema.
