5.3 Water supply / water quality
Due to the moistening of the outlet air, the water is little by little extracted from the filter unit. That is why
water must be regularly be refilled. It is ensured by the automatic monitoring of the water level and the
automatic refilling through the electrovalve.
WARNING
Danger due to unhealthy exhaust air released by contaminated water.
Make sure that the supplied water is of irreproachable hygienic and microbiological quality.
The supplied water must be clear, colourless and odourless. The water must also be
“non-putrefactive in 5 days”.
Equally, in the event of a system stoppage lasting 5 or more days, the operator must check
whether the water still meets the quality requirements or whether it needs to be changed. As
soon as an extended stoppage of the system is envisaged, it is urgently recommended to
drain off the water for this period.
The operator must also make sure that the admixture of the water with the extracted
dusts/fumes does not result in any interactions that jeopardize fulfilment of the above quality
requirements.
NOTICE
Possible damage to equipment (valves, supply line, etc.) due to contaminated water.
Make sure that the supplied water is free from suspended matter and other contaminants.
●
During operation, the ball valve (see chapter 2.1) has to be equipped with an open water supply
of ¾“.
●
When carrying out cleaning operations, you have to pay attention that no polluted water enters
the canalisation.
●
Before switching on the unit for the first time, it is advisable to let in water manually until the
water level reaches the middle of the water level indicator.
