4. Initial Inspection

4.1. Check labels, cleanliness, line cord, cracks in cabinet.

4.2. Exercise the latch mechanism, checking for normal movement.

4.3. Check appearance of peristaltic cam actuators.

4.4. Mounting bracket and its knob/screw.

4.5. Check tightness of cable strap screw.

4.6. Air-in-Line detecting surface must be clean. There is a

small note on the front case pointing to this spot.

5. Setup and Diagnostics

5.1. While holding down the upper left-hand soft key, press

the power-on button; this opens the unit in the diagnostic
mode.

Note: Hit <page> to “scroll” forward.

5.2. Check Date/time and update if necessary

5.3. Reset the PM interval.

Note: Electrical Safety: Use the strap metal button as a contact for the following.
Loosen and then re-tighten this screw to insure good chassis contact. Holding your gnd
lead tight to button helps.

5.4. Using the safety tester, check that leakage with ground open is less than 100 uA

(“Case In” on some testers).

5.5. Using the safety tester, check that ground lead resistance is less than 0.100 ohms.

5.6. Fan Check: Turn unit on unplugged; then plug in line cord. Normal faint fan noise

should now be heard. Recommended: Blow dust from fan housing after first
removing battery for access.

5.7. Battery Check: The Measured capacity > should be greater than the assigned

capacity. After a ½ hr charge, the bat bar graph should be at least 50%. If not, see
appendix for the Battery Refresh procedure.

6. Flow, Rate, Occlusion, Air-in-line, and Pressure Check

6.1. Turn unit on; <Accept>ing the current configuration (ICU for

example); Clear patient data <Yes>, and then hitting <Primary
Infusion> . Get administration set (see picture) ready by
insuring that it flows freely with no air bubbles apparent.

Note: The following for flow/volume is only a QuickCheck. See
Appendix when updating the volume cal factor is required.

6.2. Set Flow rate to 600ml/hr and Volume = 20mL.

6.3. Hit Run/Hold. With no cassette, get message “Set Out” etc.

6.4. Inset full cassette; press “Run/Hold”. In exactly 2 minutes, the

pump should deliver 20mL +/- 5% If outside this range, see
appendix.

Note: If display says “Instrument Self Check is Due”, follow on screen prompts and wait
for up to one minute for this internal task to finish.

6.5. Reprogram the unit for 7-9 mL volume; press <Run>.

6.6. Upstream Occlusion: As soon as the flow begins, pinch the upstream hose line.

Pump will halt and display “Occlusion upstream” or equivalent.

6.7. Silence Alarm: Now is good time to check this.

6.8. Downstream Occlusion: Restart the flow. Pinch the output hose. The unit often

displays “Checking Line” multiple times before finally halting with an Occlusion
message.

6.9. Air-in-Line: Before proceeding, clean both surfaces on the inner side of

the blue paddle with a damp Q-tip. False air alarms are often cured by
performing this. Run unit with empty cassette. Must get alarm.

6.10.Pressure Calibration (or check). If/when required, see Appendix.

7. Wrapup (depends on institution)

APPENDIX

Battery Refresh Cycle

1. Disconnect the battery; press the ON/OFF switch for 5 seconds; and reconnect the battery.

2. Plug unit in. Turn-on in the diagnostic mode. If software is 2.02 or higher, enter 0.0 aH in

the rated capacity for battery; hit OK. Re-enter 1.3 into the battery capacity field. Once
<ok> is pressed, cycle will start. Note that the battery bar graph will jump to 15-16 bars.

3. Leave connected to AC for 24 hours to complete cycle. The discharge, as shown by a

diminishing bar graph, will take several hours for just this phase.
