All INNOV@DM CW units are supplied with 3-way valve setted by 3 points motor. Upon request, is possible to
set an advanced precision control with 0 ÷ 10 V signal regulation.
Air presence on hydraulic circuit
It is necessary to leak air from the hydraulic circuit of unit after the connection to the external circuit. To do this,
open the frontal panels and remove the air filter; after this, open the small valve on the right-top side of the coil’s
collector (take the front side of unit in reference). Use adapted tools for the manual valve’s setting.
