5.8 Preventive maintenance
All equipment must be serviced and commissioned by qualified personnel.
This table relates to "standard" use of our units and is provided for guidance only. Servicing frequency rates must therefore be adjusted
based on your conditions of use.
5.9 Cleaning the units
On site: Keep the units wrapped for as long as possible. Upon unwrapping them, immediately make the air connections and keep the
boxes closed.
Before turning on and installation, vacuum the inside of the air handling units and, if necessary, clean the panels with a spray bottle
of solution and a soft cloth. Start up the system with just the prefilters (dust in the ducts, etc.). Wait a few hours; change the filters if
necessary and then fit all the filter stages.
Cleaning in cleanrooms and associated controlled environments
Follow the procedures in force on the site of installation.
Cleaning and decontamination can be reduced to a strict minimum with the right filtration and by following the relevant procedures.
High-pressure washers are sources of contamination and therefore prohibited. Clean with either a spray bottle filled with a cleaning
solution or disinfectant and soft cloth or special wipes.
Reminder: Contaminants may be brought in each time a door is opened in a cleanroom or associated controlled environment.
