Cleaning of the filter must be done when pressure differential across the disc reaches 0.5 kg/cm2 or when the clogging indicator red button pops up.

To start cleaning mode of filter, turn the handle (top of the filter) 90 degree in clockwise direction.

Cleaning operation starts, system pressure might increase during clearing operation.
