Inspection
Ensure all cords and connectors are in good condition and void of any cuts, cracks, or frays.
Ensure units are clean and void of any cracks or other signs of damage.
Performance Test Setup
Set up the system for normal operation. Provide a 0.5 liter source of fluid at 20 °C ± 2 °C. Measure the temperature within 22.9 cm (9 in) of both the input and output
connections of the Disposable Cartridge by inserting a T connector in the direct fluid path, which will accommodate a temperature probe. Connect the temperature probes to a
meter capable of measuring between 10 °C and 60 °C with 0.1 °C accuracy. Prime the IV line setup according to standard IV protocols. Turn the enFlow system on and establish a
fluid flow of 100 ± 20 mL/min. Wait for the temperature probes to stabilize.
Record the input fluid temperature. Input fluid temperature 20 °C ± 2 °C.
Record the output fluid temperature. Output fluid temperature 40 °C ± 2 °C.
Over-Temperature Alarm Check
Use performance testing setup. Change the source of fluid’s temperature to 50 °C ± 2 °C. Turn the enFlow system on and establish a fluid flow of 100 ± 20 mL/min. Wait for the
temperature at the probes to stabilize.
Record the input and output fluid temperatures.
The High Priority Over Temp Alarm occurs within less than 20 seconds of reaching input temperature. (See Appendix C.)
High Priority Alarm indicated by Audible beep and Over-Temp message in Red appearing on the Controller
Red Temperature LED flashes on the Warmer, also indicating a High Priority Alarm
Electrical Safety
Follow safety analyzer manufacturer’s instructions
Test leakage current at the AC power cord using a safety analyzer.
Test leakage current of the Warmer to the saline in the IV line using a safety analyzer.
