Inside the circuit, the incoming pressurized medical gas, is sent to the mixing block by means of a device operated by a valve controlled by
the electronic circuit of the device. When the device is turned off the pressurized medical gas, even if introduced in the device, is not
delivered because intercepted by the electrovalve in closed position. Everything is controlled by the electronic circuit of the device, which
also controls the main breathing parameters.
This diagram is provided only to illustrate the operation of the device. It is not allowed to
intervene in any way on it as well as on the electronic circuit. If opening of the case of the device or any other type of unauthorized
modification will be found, the warranty would be voided and Spencer Italia will not have any liability related to the functionality and use
of the product.

Guide and Manufacturer's Declaration
190 ventilator is intended for use in the electromagnetic environment specified below. The customer or the user of the ventilator 190 must ensure that it is
used in such an environment.
EMISSION TESTS
Conformity
Guide to the electromagnetic environment
Emissions in RF CISPR 11
Group 1
The 190 ventilator uses RF energy only for its
internal functions. Its RF emissions are therefore
very low and unlikely to cause any interference
with electronic equipment nearby.
Emissions in RF CISPR 11
Class B
The 190 ventilator is suitable for use in all
environments including domestic as well as those
directly connected to a low-voltage public
network source supply of which supplies
buildings used for domestic purposes.
Harmonic emissions IEC 61000-3-2
Emissions as a result of voltage fluctuations /
