6.0 Functional Check and Safety Inspection

Procedures within this section should be performed only by qualified
personnel such as biomedical electronics technicians or certified clinical
engineers familiar with repair practices for servicing medical devices and
accessories in accordance with this manual. Damage to the inflator or
malfunction could otherwise result.
Perform the following procedures every six months to assure optimum performance,
dependability, and safety.
6.1 Enclosure
Unplug the inflator from the mains. Examine the enclosure. Check that screws are tight,
labels and markings are legible, and air vents are free of dirt. Examine the power inlet for
cracks and bent, broken, or missing pins.
6.2 Protective Earth Continuity Test
Measure the resistance between the protective earth pin of the inflator's power inlet and
the metal enclosure. It should be less than 0.5 ohms. If it is greater than 0.5 ohms, check
the condition of the protective earth connections inside the inflator and the enclosure
screws. Remove the front cap for access to the interior of the inflator. Refer to sections 8
and 9.
6.3 Current Leakage Test
Measure the current leakage between the inflator enclosure and protective earth. It should
not exceed 400 µA for any combination of line polarity with the protective earth open. It
should not exceed 800 µA with neutral open (single fault). If the inflator fails the current
leakage test, suspect the motor or the power inlet/EMI filter. Replace these components
per section 8 or return the complete inflator to your local dealer for repair.
