General:
• A 'Preventive maintenance' must be performed at least once every year as long as the unit is not used more than normal. Normal operation is estimated to correspond to approx. 5,000 hours of operation.
• The Battery modules shall be replaced every three years.
• The internal Lithium batteries on PC 1771 and
PC 1772 shall be replaced every five years.
• After or in combination with performing the 'Preventive maintenance' described in this chapter, a 'Routine cleaning' and an 'Extended cleaning of Inspiratory channel' must be performed. For cleaning procedures, refer to the 'Servo-i Ventilator System – User's manual'.
• In some parts of the Preventive maintenance, as described in this chapter, access to the Field Service System (FSS) is required.
• Some optional equipment used with the Servo-i, but not covered by this Service Manual, may also demand maintenance actions. Refer to the optional equipments documentation.
Example on such optional equipment are:
– Humidifier
– Compressor Mini.
Equipment:
• Standard service tools.
• Barometer (or information about the actual barometric pressure).
• Access to the Field Service System (FSS ). Recommended but not required.
• Preventive maintenance-kit containing all parts
needed during the maintenance.
