2.3 Flow adjustment
Change transmission ratio
Change the frequency supply of the motor
Use a two speed motor
Discharge excess flow and silence it
Warning : Do not use relief valve to discharge excess flow
Warning : Do not recirculate flow to ROBOX DV inlet.
Warning : Do not adjust flow by throttling inlet or outlet pipe.
2.4 Noise level
Noise level radiated from the surface of ROBOX DV is indicated at page 4 as Sound Pressure Level measured according to ISO 3476 at 1 m
distance from ROBOX DV and in free air (tolerance +/- 2 dB(A))
Warning : For high compression ratio and for high speed of rotation noise level of ROBOX DV can be higher
than 85 dB(A).
Note : The noise radiated from the piping connected to ROBOX DV can be different from the value indicated in
this manual because it depends by the piping configuration.
