Appendix E: Preventive maintenance procedure

Employ local regulations to determine the frequency of required testing (i.e. Earthing Impedance, Leakage Current) for the enFlow Warmer (Model 100) and

Controller (Model 121).

Functional and Operational Testing Protocols

Inspections

Temperature Readout Display and Status Indicator Lights

Electrical Safety

Simulated Use Performance Testing: enCheck Model 400 or Alternative Method

Alarm Test: enCheck Model 400 or Alternative Method

Inspections

1. Ensure all cords and connectors are in good condition and void of any cuts, cracks, or frays. Discoloration from cleaning solutions and disinfectants is

normal and to be expected.

2. Ensure the unit is clean and void of any cracks or other signs of damage. If signs of damage are visible, remove it from service and contact Vital Signs as

soon as possible.

Temperature readout display and status indicator lights

1. Plug the Controller into a functioning power supply. Set the MAINS power to ON. Confirm the Controller power indicator is illuminated and displaying a

green color. Confirm the display panel (Controller only) shows in yellow the conditional message "not heating. "

2. Connect the Warmer without a Disposable Cartridge inside to the Controller. Confirm the beep signaling connection. Confirm the display continues to

show the conditional message "not heating. " Confirm the Warmer power LED is flashing green.

Electrical safety

1. Ground wire resistance

Equipment

enFlow Controller

Safety analyzer with test lead

Purpose

The purpose of this test is to check the resistance in ohms of the ground pin to the chassis. For purposes of this check, the pole screw will be considered to be

the ground pin, and the chassis is the Controller.

Procedure

A. USA (Tests the equipment inclusive of its power cord.)

1. Remove the Controller from the IV pole.

2. Reinsert the pole clamp screw; screw in tight against the case. (Do not over-tighten.)

3. Attach the banana end of the ground lead on the safety analyzer to the pole clamp screw.

4. Plug the power cord of the Controller into the safety analyzer.

5. Set the function knob on the safety analyzer to ground wire resistance.

6. Set the ground switch to normal.

7. Set the polarity switch to the off position.

8. Power the safety analyzer by plugging in and setting the MAINS power to ON.

9. Record the resistance reading. An acceptable reading is a maximum of 500.0 mΩ.
