These parts should be washed and disinfected by using the methods to be presented later on. The cleaning
operation should be carried out at least once a month. This cleaning should be repeated for the places known
for bacteria to have a potential to reproduce them.
Cleaning of Outer Surfaces of Devices; As the outer surfaces of the devices are painted, only fulfilling
the cleaning operation will suffice. This cleaning should be carried out in accordance with the criteria
and methods described below.
Each part will have a different cleaning and disinfection procedure due to its unique features. For that
reasons, the procedures are presented below under three main titles.
Procedure of cleaning the technical parts
Procedure of cleaning and disinfecting the inside of operative parts
Procedure of cleaning the outer part of the device
13.6.3.1 Cleaning Procedure of the Technical Part
Technical parts should be cleaned with a vacuum and replaceable paper filtered cleaning instrument (like a
vacuum cleaner) and a soft brush. There is n need for disposing the paper filter with septic wastes unless
otherwise stated to technicians.
Fulfill the following instructions throughout the cleaning process:
Stop the device and take the main switch and the service switch to the off position to cut the electricity.
Post onto the electricity panel a note stating that the device has been serviced and the electricity switch
should never be taken to the on position.
Open the cover of the technical part by using the appropriate spanner.
Make the vacuum cleaner absorb the dust on the equipment and the wall. This operation should be carried
out from the top towards the bottom.
Wipe the device cover with a damped clothe.
Then wipe carefully the side walls and the cover with a clean and dry clothe.
Close the cover carefully in order to avoid damages to the power switch.
If operative parts and the outer surface are not to be cleaned, take the power switch to the on position to
supply electricity to the device again. The device is now ready for working.
13.6.3.2 Procedure of Inner Cleaning and Disinfection of Operating Parts
İnner surfaces of operative parts are continuously in touch with outdoor air and and the indoor air (for
mixing air devices). Even though filters are located inside the unit and in the outdoor air input this touch
causes micro-organisms to settle and reproduce on the inner surfaces of the device. Thus these surfaces
should be periodically cleaned and disinfected.
