Operation and maintenance, Discfilter HPF2200-series PFLC

7.4 Filter panels

NB Prior to servicing, read section 2.7.

7.4.1 Additional cleaning

Additional cleaning of the filter panels may be necessary. The need for additional cleaning be-

comes clear if the frequency of automatic backwash starts increases. Additional cleaning can be 

chemical cleaning or cleaning with a high pressure washer.

When using a high pressure washer a wash pressure of max. 80 bar may be used. Maxi-

mum allowed water temperature is 60 °C. Never hold the cleaning nozzle directly against 

the filter media.

A chemical cleaning programme can be started in accordance with section 7.4.2.
