Legionella prevention system
17.4.1. General.
As of mid-2020, the UVC6000 legionella prevention system
will be used for various TERA dust control unit models as an
option.
Legionella are bacteria that could cause legionnaires’
disease.
Infection takes place through breathing in the
bacteria in minuscule drops of water that are spread in the air
(shower, whirlpool, dust control unit). The bacteria can grow
at 20°-50°C in stagnant water.
Simple basic rules of prevention are:
•
Always use mains water.
•
Allow water to flow through the water hose before
connecting.
•
Carefully empty the dust control unit after use.
The UVC6000 kills the bacteria that are present in the water
by means of ultraviolet light, significantly reducing the risk of
spreading legionella.
The UV unit is placed against the left column of the TERA, the
control panel against the right column.
17.4.2. Starting.
