3.9.1. HEPA12 Filter
For safety reasons, between the working area and the defrost pump, there is a HEPA12 filter that filters
possibly dangerous pathogens in the vapors.
This filter must be changed after the defrost pump has worked for 250 hours.
The software advises you that the filter life is finished with the message “Filter needs to be replaced. Please
do it”, at the starting of the first freezing program of the day.
Change the HEPA12 filter following the instructions in the chapter 4.4.1 How to change the HEPA12 filter.
Check the cool trap daily. If needed, empty it. Refer to chapter MAINTENANCE 4.3.
It is strongly suggested to do a defrost cycle once a day.
Defrost settings are under Service settings, accessible only to Service personnel.
Contact application@milestonemedsrl.com for further information.
The preset defrost temperature is 30°C, but during the cycle higher temperature values
can be reached.
Avoiding HEPA12 filter change, can be dangerous for operator safety.
To change the filter, refer to chapter 4.4.1.
