Operating Procedures
AC Light On whenever pump is plugged in. Rate Control Knob Increases or decreases flow rate desired. ON Powers the pump. OFF Shuts pump off.
START/HOLD Starts pump rotor to deliver feeding formula and alternately puts unit on HOLD. HOLD is used to stop fluid flow to: 1. Correct alarm condition (alarm is silenced) 2. Change the flow rate 3. Change pump set NOTE: IF THE PUMP HAS BEEN PLACED ON HOLD AND NOT RESTARTED WITHIN 2.5 MINUTES, AN ALARM WILL SOUND. NOTE: BATTERY WILL CHARGE WITH PUMP PLUGGED INTO WALL OUTLET, EVEN WHEN OFF BUTTON HAS BEEN PRESSED.
Normal Operations Insert hospital grade plug into AC wall outlet.
Battery Operation Unplugging the pump from the AC line outlet will automatically put the pump on battery power. A new battery, when fully charged, will operate the instrument for more than 24 hours at 125 milliliters per hour. Approximately 15 minutes prior to battery discharge, a low battery alarm will occur, (see alarm section). When complete discharge occurs, the pump will automatically turn itself off. NOTE: AS THE BATTERIES GET OLDER, THE TIME FROM LOW BATTERY ALARM TO COMPLETE DISCHARGE MAY BE LESS THAN 15 MINUTES. The battery will charge continuously during AC line operation. To recharge battery, insert hospital grade plug into AC wall outlet. Battery will automatically begin charging. The recharge time for a fully discharged battery is approximately 15 hours. The battery will charge whenever the pump is plugged into a wall outlet, even when the OFF button has been pressed. To be certain that power to all circuits has been disconnected, the power cord must be unplugged from the wall outlet.
Beginning Administration Below are general instructions for inserting all Sherwood Medical Pump Sets into the KangarooŽ 224 Feeding Pump. 1. Press ON. 2. Wait while pump performs system check. 3. When flow rate is displayed, set desired rate in ml/hr by turning rate control knob on side of pump.
4. Slide drip chamber into upper drip chamber guide.	5. Seat and secure chamber in lower drip chamber guide. (A).
6. Remove distal connector protective cover. 7. Slowly open clamp and fill entire line with fluid, leaving a few drops of fluid in the drip chamber.  NOTE:AVOID FILLING THE DRIP CHAMBER MORE THAN HALF FULL. 8. Close clamp 9. Attach distal connector to feeding tube.
10. Grasp silicone tubing and gently stretch around rollers. Insert retainer into retainer lock (B). Thread tubing over tubing guide (C). Secure latch over tubing (D). VERIFY THAT THE PUMP SET IS PROPERLY LOADED IN THE PUMP BEFORE PROCEEDING. AN IMPROPERLY LOADED PUMP SET COULD RESULT IN UNCONTROLLED FLOW AND POSSIBLE PATIENT INJURY.  11. Open control clamp. 12. Press START/HOLD. 13. Proceed with feeding.

Alarms

The Sherwood Medical KangarooŽ 224 Feeding Pump has been designed to provide audible and visible alarms under several conditions where proper performance cannot be maintained. When an alarm occurs, press the START/HOLD button on the pump and perform the necessary procedures to correct the alarm condition. NOTE: THE VISIBLE ALARM IS IN THE FORM OF A MESSAGE SHOWN ON THE DISPLAY.

Visible Alarm Definitions

No Set (no SEt) The feeding set is not installed or is installed improperly. See Operating Procedures for installation instructions. Flow Error (FLO Err) The feeding container is empty. To correct this situation, if more feeding is required, refill the container with the desired amount of formula and follow the steps in the Operating Procedures of this manual. The feeding container, the feeding set tubing, or the feeding tube itself has become occluded beyond the pump's capability to pump. Alarm will activate at approximately 12 psi (8~.7 kPa). To correct this condition, determine where in the system the occlusion has occurred. Correct occlusion condition. Press START/HOLD switch. Continue with feeding. The drop sensors are blocked and will not be able to detect drops as they come through the drip chamber. To correct this condition, check drop sensors on inside of upper drip chamber guide and clean off any material that may be blocking sensors. Low Battery (Lo bAt) This alarm is activated when the battery begins to run down and flow rate accuracy can no longer be maintained. The low battery alarm occurs approximately 15 minutes before complete discharge. When complete discharge occurs, the pump automatically turns itself off. To correct this condition, plug the pump into an AC wall outlet. When the pump is connected to a wall outlet, it will continue to operate and charge the battery at the same time. Once the low battery alarm has sounded, it will take approximately 15 hours to fully recharge. Hold Error (Hid Err) If the pump is left in the hold mode for approximately 2 1/2 minutes "HOLD ERROR" will alarm. System Error (Sys Err) Rotor is not turning while pump is in start mode. NOTE: DOTS WILL FLASH ACROSS TOP OF LED DISPLAY WHILE PUMP IS RUNNING. Rotor is turning, but is not detected by rotor sensors. Do not try to repair pump. Return pump for technical service. NOTE: FOR ALL ALARM CONDITIONS, PRESSING THE START/HOLD BUTTON WILL SILENCE THE AUDIBLE ALARM. THE VISIBLE DISPLAY WILL CONTINUE TO FLASH UNTIL THE START/HOLD BUTTON IS PRESSED AGAIN.

Troubleshooting Guide
Listed below are some of the probable causes of alarm conditions and their corrections.
Symptom	Probable Cause	Corrections
Flow Error Alarm (FLO Err)	Feeding Container is empty.   Feeding tube or feeding set tubing occluded.         Drip chamber is improperly placed in pump. Drip chamber walls are coated with feeding formula.   Sensors in upper drip chamber guide are blocked.	Refill feeding container. If bag has been in use for 24 hours, replace Locate point of occlusion and correct. Note: occlusion may occur upstream from pump. Feeding Container Feeding Pump Set (control clamp closed) Feeding Tube-patency of feeding tube should be checked Check to make sure drip chamber is properly "locked" in position is drip chamber. Check to make sure formula is not preventing detectors from proper operation. If formula cannot be removed from inside walls of chamber via chamber manipulation, replace set. Check to make sure formula is not preventing detectors from proper operation. If formula cannot be removed from inside walls of chamber via chamber manipulation, replace set.
Low Battery Alarm (Lo bAt)	Battery has been run down below point of maintaining accuracy of pump.	Plug pump power cord into outlet.
No Set (no SEt)	Pump set has been improperly placed into pump.	Check to make sure only KangarooŽ Pump Pet has been placed onto the pump. Check to make sure that retainer clip on pump set has been properly positioned into retainer lock on pump.
System Error (SYs Err)	Rotor is not turning while pump is running. Rotor is turning but is not detected by rotor sensors.	Return pump for technical service.
