operating range", Rev. 3, dated 2009-03-31.

The following operational specifications apply for the different components:

C3T cavitation unit

Minimum flow rate: 540 m3/h; with differential pressure between 1.6bar and

2.4bar for the model tested during ship baord test.

C2E disinfection unit

The hydrogen trap and ventilation of the C2E unit, together with all 

electrical

and electronical sensors in the C2E unit must be installed according to the
