Do not use scouring powder, organic solvents (may damage
materials) or solvent based cleaning fluids (benzene, alcohol,
spot remove). As is commonly known,the ingredients in
disinfectants are hazardous to your health. Ensure that room is
well ventilated when using any disinfectant. Follow the
instructions for using disinfectants.

 

Do not spray the unit.The cleaning fluid must not seep into the
generator. Substituted phenol based or chlorine releasing
disinfectant can weaken materials and are not recommended.
The same restrictions apply to undiluted solutions with a high
alcohol content (e.g. for disinfecting hands). Disinfectant
sprays should generally not  be used, the spray can seep into
the system,and safety features can no longer be guaranteed
(possible damage to electrical components, formation of
flammable mixtures of air and the solution vapour).

 

 

To disinfect surfaces, we recommend common liquid solutions of aldehyde-based or
ampholytic surfactant -based disinfectant.
