Servicing

WARNING
Inspection and repair should only be performed by an authorised agent. Under no circumstances
should you attempt to service or repair the device yourself. Failure to do so could void your Astral
device warranty, damage the Astral device or result in possible injury or death.
Note: Retain the original packaging of the Astral device for use when shipping to/from an authorised ResMed

WARNING
•
To prevent the risk of cross-contamination, an antibacterial filter, placed on the inspiratory port
is mandatory if the device is to be used on multiple patients as under some fault conditions,
expired gas may be returned through the inspiratory port.
•
The expiratory module, internal antibacterial filter, expiratory flow sensor and blue membrane
come into contact with exhaled gases but do not form part of the inspiratory pathway.
