• Before opening the water inlet, guarantee that the humidity calibrator is no longer
under pressure. (Controller turned all the way to the left, if HUMOR is already in
operation, display RH > 90% )

• Before connecting the compressed air, guarantee that the controller is turned all
the way to the left.
