Battery Replacement and Shipping Regulations
Only trained technicians at an authorized ZOLL Service Center can replace the ventilator’s
battery. Contact your local service center for return instructions and please note the following:
•
Shipping of the ventilator’s battery should always use proper State of Charge (SOC), which
must never exceed 30%. The ventilator’s Rechargeable Li-Ion battery follows these and
other important regulations, which IATA/DOT UN 38.3 mandates.
•
The ventilator’s battery is less than 100 Wh, and thus is Classified as Class 9 Exempt and
does not require Class 9 labeling or marking.
•
Always check all applicable local, national, and international regulations before transporting
a Lithium-Ion battery.
•
Transporting an end-of-life, damaged, or recalled battery may, in certain cases, be
specifically limited or prohibited.
Calibration Checks
The ventilator continuously performs a self check to monitor the pneumatic system.
The ventilator’s calibration is checked as part of the annual service procedure. You should send
the ventilator for preventative maintenance:
•
Every 12 months.
•
Whenever significant usage or rough handling warrants a shorter period between
preventative maintenance inspections.
•
Whenever you suspect the device is not functioning properly.
•
Following mass deployment before the device is returned to storage.
If the ventilator fails the self-check, restart the device, if it fails again, it should be returned to
ZOLL or an authorized Service Center for calibration.
Electrical Safety Check
The ventilator’s power system has an internal protection system that continuously monitors the
device. In event of a fault or failure condition. the device triggers an alarm.
The ventilator is double insulated, and is categorized as both Class I and Class II meeting all
regulatory codes. When attached to the an AC power source the ventilator’s external AC/DC
power supply protects the device in two steps:
1. Class I: Basic Insulation: the earth grounding provides a dissipation route under this fault
condition. Under fault conditions with resistances of 100 m
Ω
or less, the AC/DC power
supply shunts the current away and opens the safety fuse.
2.
Class II - Supplementary Insulation: the impedance of the isolation barrier integral to the
AC/DC power supply provides the protection to the user and patient. Under high voltage fault
conditions, the device relies on isolation of the high voltage internal circuitry from the
equipment's enclosure as the safety countermeasure.
Protection against electric shock does not rely on basic insulation only, the device has
additional safety precautions that prevent accessible metal parts from becoming live should the
basic insulation fail.
Protective grounding testing, typical for many medical devices, is applicable only to Class I
equipment. The ventilator’s electrical safety design is not dependent on earth grounding as the
means of protection.
