7.3 Maintaining and cleaning components
All installed components are either freely accessible for cleaning or can be pulled out of the AT4F ATEX unit or removed
after opening the inspection doors/removing the inspection cover.
„
Coarse dirt in the housing can be removed using an industrial vacuum cleaner.
„
Remove other dirt with a damp cloth.
Cleaning
WARNING
Risk of explosion due to electrostatic discharge.
When cleaning the unit type plates, the type plates, roof film and the cable duct cover, the unit
can become electrostatically charged and cause an explosion.
„
Only clean the AT4F ATEX unit with a damp cloth.
„
Only lukewarm water, possibly with a mild detergent without perfume, should be used for cleaning. Do not use me-
chanical aids, e.g. sharp tools, grinding stones, wire brushes, files, steel wool made of unalloyed or low-alloy car -
bon steel, etc.
Disinfection
„
If disinfection is necessary with air handling units, a check must be performed at a suitable and non-critical point
before using disinfectants to ensure that the disinfectant does not cause damage to the seals, surfaces, etc.
ATTENTION
Only lukewarm water, possibly with a mild detergent without perfume, should be used for
cleaning of the inspection glass.
No cleaning agents and disinfectants that attack the materials used in the HV unit are permit -
ted to be used.
The following points are to be observed for the use of disinfectants and for carrying out the disinfection:
„
Specifications from the safety data sheet of the disinfectant must be complied with.
„
The disinfectant must be used according to the manufacturer's instructions (e.g. concentration, exposure time,
etc.).
„
Remove the disinfectant completely.
„
Dispose of the disinfectant and the necessary aids correctly.
„
Disinfectants containing chloride in combination with a strong continuous action of moisture (e.g. areas around
spray humidifiers) can cause corrosion damage to (even coated) materials and may not be used in this application.
Also observe the following:
„
Do not use a high-pressure cleaner for cleaning or disinfection.
„
Detergents or disinfectants must not penetrate into electrical or mechanical system parts.
„
If necessary, completely reinstall the protective and safety installations or coverings removed for cleaning or disin-
fection and check their functionality.
(Subsequent) damage resulting from a nonetheless carried out or incorrect application of corresponding disinfection or
cleaning are at the expense of the initiator.
