Cautions The following cautions apply any time you work with the ventilator. • Ensure that the voltage selection and installed fuses are set to match the voltage of the wall outlet, or damage may result. • A battery that is fully drained (i.e. void of any charge) may cause damage to the ventilator and should be replaced. • All accessory equipment that is connected to the ventilator should comply with CSA/IEC601/UL2601. • To avoid damage to the equipment, clean the air filter regularly. The following cautions apply when cleaning the ventilator or when sterilizing ventilator accessories. • Do not sterilize the ventilator. The internal components are not compatible with sterilization techniques. • Do not gas sterilize or steam autoclave tubing adapters or connectors in place. The tubing will, over time, take the shape of the adapter, causing poor connection and possible leaks.
