19.3 Desinfection
The use of chemical disinfectants for daily maintenance of the panels is not recommended as it may reduce
their efficiency and useful life. If chemical products need to be used, because of a long time without operation
or any other reason, an effective method is to immerse the panels in a chlorine-based disinfectant, such as
sodium hypochlorite (bleach) or sodium peroxycarbonate. If chlorine-based disinfectants are used, they should
not be mixed with an acid solution due to the potential formation of toxic chlorine gas.
Remark:
The manufacturer’s safety steps for the disinfectant solution should be followed.
The inorganic high efficiency panel the HEF2 Series cassettes includes agents, such as silver ions, that inhibit
the growth of bacteria and fungi. This works against bacteria and mold, but not as a sterilizing agent.
The same bleach disinfectant solution may be appropriate to disinfect the other components. The number and
periods of application of the disinfection processes must be established by the person responsible for the
facility, taking into account the time of use of the equipment, its location, piping system and water quality, for
example.
Therefore, good operating practices, based mainly on an adequate control of the bleed-off system and
watering/emptying, should be followed.
An additional and highly recommended practice would be to treat to the humidifier supply water.
