3100B HFOV Operator Manual - CareFusion

Operator’s Manual 69
Scheduled Periodic Maintenance
There are three other scheduled maintenance intervals suggested by CareFusion, based on
accelerated life testing data and clinical usage history. These are:
Troubleshooting
1. Every three (3) years or 4,000 operating hours, whichever comes first, replace the
Oscillator Subassembly (the “driver”) with a new or rebuilt unit that has new diaphragms
and support spiders (the parts subject to flexure fatigue). A factory-trained technician
must do this replacement.
2. Every 8,000 operating hours or six (6) years, whichever comes first, replace all parts
subject to usage wear and aging (for example, solenoid valves, regulators, plastic tubing,
and cooling fans) and the Oscillator Subassembly. A factory-trained technician must do
the replacement.
3. Every seven (7) years, replace the Driver Power Module. A factory-trained technician
must do the replacement.
This section is intended to assist the operator in identifying and correcting any apparent malfunctions of
the 3100B System. For assistance, the CareFusion Technical Support Department can be reached 24
hours a day, 7 days a week.
Special Environmental Considerations
Excessive amounts of dust and lint in the area around the 3100B can cause malfunctions due to
blockage of the cooling fan input at the base of the instrument. We recommend keeping the instrument
environment as clean and well-ventilated as possible, along with the normal maintenance of the cooling
fan filter as described earlier in this chapter.
Electrostatic Discharge
The 3100B is designed and tested to withstand normal to high amounts and occurrences of
Electrostatic Discharge (ESD). Under certain circumstances, however, it is still possible for ESD to
cause component damage to the 3100B. ESD takes place when a person has built up enough static
electricity on their body and clothing that a “shock” occurs when they touch something conductive, like
metal or another person. This can damage instrument components if the charge is of sufficient strength.
To avoid this, especially during conditions of extremely low humidity when the levels of ESD are
generally high, touch the outer metal cabinet of the instrument before touching any other component.
Electromagnetic Interference
The 3100B is also designed and tested to withstand normal amounts and occurrences of
Electromagnetic Interference (EMI). Under certain circumstances, however, it is possible for EMI to
effect the components of the system. EMI consists of electromagnetic waves from one electronic device
interfering with the function of another electronic device. These waves can be radiated through the air
or conducted through electrical wiring. Likely causes of troublesome EMI in the hospital setting include
(but are not limited to) MRI systems, lasers, diathermy equipment, cauterizers, transmitting computers,
and hand-held radio transmitters.
