Periodic Test of the Internal Battery
Your ventilator continuously and automatically checks the state of the internal battery, even when the
internal battery is not used as the main power source.
However, the battery charge status should be checked MONTHLY by disconnecting the ventilator
from external power supplies (refer to section
6.2, “Battery Operation” ). Such a test is imperative after
opening the ventilator or after a prolonged period of non-use (one month or more), in order to ensure
the correct operation of internal connections linking the battery to other components.
Replacement of the Internal Battery
The internal battery should be replaced when the battery capacity drops below 3450 mAh. Keep in
mind that, for environmental protection, the ventilator and its components—including its internal
battery—cannot be disposed of with household waste. You must submit the ventilator and its
components for suitable selective collection and possible recycling and observe all applicable
regulations.
8.3 Service Assistance
In the event of a problem with the ventilator, refer to chapter 3, “Alarms and Troubleshooting” . If you
cannot determine the cause of the problem, contact your equipment supplier or Puritan Bennett.

Caution
Do not store the internal battery, either installed within or removed from the ventilator, for more than
two (2) years. Storage here is taken to mean a period of continuous non-use.
Note: As
the total number of battery charge/discharge cycles approaches 300, a drop in potential of
as much as 20% may be detected.
WARNING
•
If a problem with the ventilator is suspected, FIRST CHECK THAT THE PATIENT IS NOT IN DANGER. If
necessary, remove the patient from the ventilator and provide an alternative means of ventilation.
•
Do not attempt to repair or otherwise service the ventilator yourself. Doing so might endanger the
patient, damage the ventilator, and/or void your warranty. Only qualified service personnel should
repair or service the ventilator.
