While in storage, every
two months

once a month
Every 10,000 hours or
10
two years , whichever

Every 30,000 hours or
six years, whichever
10

This is the recommended schedule for typical clinical or home settings. Some environmental
conditions may require you to perform the maintenance procedures more frequently.
8
For the number of hours the ventilator has been in service, see Extended Features in the LTV Operator's Manual.
9
If the battery is deeply discharged, it may take several charge and discharge cycles before it is at full capacity.
10
10,000 hour, two year and/or 30,000 hour, six year extended maintenance and ventilator repair must be performed by a
service technician who has been trained and certified by CareFusion.
11
Replacement at 10,000 hours or 2 years is based on normal use of up to 200 charge cycles. The battery may need to be
replaced more frequently if it is being charged more often. The battery should also be replaced any time it fails to reach a
full charge, or if the ventilator runs for less than 40 minutes on a fully charged battery.
