INTRODUCTION
The Hospira Plum A+®3 infusion system is designed to meet the growing demand for
hospital wide device standardization. The system consists of three component infusers,
which are designated line 1, line 2, and line 3. By incorporating three lines into one unit,
the Plum A+®3 provides three primary lines, three secondary lines, and piggyback fluid
delivery capabilities. The Plum A+®3 serves a wide range of general floor and critical care
needs. Compatibility with the LifeCare®5000 PlumSet®administration sets and
accessories make the Plum A+®3 infusion system convenient and cost-effective.

1.5 USER QUALIFICATION
Technical Service Manual 1 - 5 430-95424-002 (Rev. 01/06)
1.5
USER QUALIFICATION
The infusion system is intended for use at the direction or under the supervision of licensed
physicians or certified healthcare professionals who are trained in the use of the infusion
system and the administration of parenteral and enteral fluids and drugs, and whole blood
or red blood cell components. Training should emphasize preventing related IV
complications, including appropriate precautions to prevent accidental infusion of air.
The epidural route can be used to provide anesthesia or analgesia.
1.6
ARTIFACTS
Nonhazardous, low-level electrical potentials are commonly observed when fluids are
administered using infusion devices. These potentials are well within accepted safety
standards, but may create artifacts on voltage-sensing equipment such as ECG, EMG,
and EEG machines. These artifacts vary at a rate that is associated with the infusion rate.
If the monitoring machine is not operating correctly or has loose or defective connections
to its sensing electrodes, these artifacts may be accentuated so as to simulate actual
physiological signals. To determine if the abnormality in the monitoring equipment
is caused by the infuser instead of some other source in the environment, set the device
so that it is temporarily not delivering fluid. Disappearance of the abnormality indicates
that it was probably caused by electronic noise generated by the infuser. Proper setup and
maintenance of the monitoring equipment should eliminate the artifact. Refer to the
appropriate monitoring system documentation for setup and maintenance instructions.
1.7
INSTRUMENT INSTALLATION
PROCEDURE
CAUTION: Infusion system damage may occur unless proper care is exercised
during product unpacking and installation. The battery may not be fully charged
upon receipt of the infuser. Do not place the infuser in service if it fails the self test.
CAUTION: Infusion system performance may be degraded by electromagnetic
interference (EMI) from devices such as electrosurgical units, cellular phones,
and two-way radios. Operation of the infusion system under such conditions should
be avoided.
Accessory equipment connected to the analog and digital interfaces must be certified
according to the respective IEC standards (e.g., IEC 60950 for data processing equipment,
and IEC 60601-1 for medical equipment). Furthermore, all configurations shall comply
with the system standard IEC 60601-1-1. Any person who connects additional equipment
to the signal input or output part configures a medical system, and is therefore responsible
for ensuring that the system complies with the requirements of IEC 60601-1-1. If in doubt,
contact Hospira Technical Support Operations (see Section 6.1).
The instrument installation procedure consists of unpacking, inspection, and self test.

1.7.1
UNPACKING
Inspect the shipping container as detailed in Section 1.7.2. Use care when unpacking the
infusion system. Retain the packing slip and save all packing material in the event it is
necessary to return the infuser to the factory. Verify the shipping container contains a copy
of the system operating manual.
1.7.2
INSPECTION
Inspect the shipping container for damage. Should any damage be found, contact the
delivering carrier immediately.
CAUTION: Inspect the infuser for evidence of damage. Do not use the device if it
appears to be damaged. Should damage be found, contact Hospira (see Section 6.1).
Inspect the infusion system periodically for signs of defects such as worn accessories,
broken connections, or damaged cable assemblies. Also inspect the infuser after repair
or during cleaning. Replace any damaged or defective external parts.
1.7.3
SELF TEST
CAUTION: Do not place the infuser in service if the self test fails.
Note: Do not place the infuser in service if the battery is not fully charged. To make
certain the battery is fully charged, connect the infuser to AC power for six hours
(see Section 8).
Note: If an alarm condition occurs during the self test, cycle the power and repeat the
self test. If the alarm condition recurs, note the message and take corrective action
(see Section 6). Repeat the self test. If the alarm condition continues to recur, remove
the infuser from service and contact Hospira.
Note: Records prior to the date the infuser is received may be from the manufacturing
process. Disregard any events from dates prior to receipt of the infuser.
Note: When performing the self test, line 1, line 2, and line 3 must be tested.
However, if appropriate, the test may be performed on all lines concurrently.
To perform the self test, see Figure 1-1, and proceed as follows:
1. Connect the AC power cord to a grounded AC outlet. Verify the charging/line
indicator CHARGE illuminates and an alarm beep sounds.
2. Without a cassette installed, press [ON/OFF] to turn on the infuser.
3. The LCD screen briefly displays the SELF TEST screen (see Figure 1-1).
Note: If the SELF TEST screen does not appear, contact Hospira.
4. After the self test is complete, the message “INSERT PLUM SET CLOSE LEVER”
appears.
5. Verify the time and date. To set the time and date, see Section 1.8.3.

1.7 INSTRUMENT INSTALLATION PROCEDURE
Technical Service Manual 1 - 7 430-95424-002 (Rev. 01/06)
6. Open the cassette door and insert a primed cassette. Close the cassette door.
The cassette test is complete when the “CASSETTE TEST IN PROGRESS” message
disappears.
Note: The message “MECHANISM INITIALIZATION IN PROGRESS” may briefly
appear prior to the “CASSETTE TEST IN PROGRESS” message.
7. The “CLEAR SETTINGS?” message may appear. Press the [YES] softkey.
8. Press [ON/OFF] to turn off the infuser.

BIOMED SETTINGS
The biomed settings screens contain the following options that can be changed or reviewed
by qualified personnel:
- IV screen parameters
- Alarms log
- Set time and date
All infusers (new or refurbished) are shipped with factory settings (see Table 1-2).
Note: Biomed screens do not time out for the Infuser Idle alarm or No Action alarm.
Note: The battery will not be detected in the biomed service mode.
To access the biomed settings, proceed as follows:
1. Open the door and turn on the device. The infusion system will perform a self test.
2. After the self test is complete, the message “INSERT PLUM SET CLOSE LEVER”
appears. Press the decimal [.] key, then [START], and verify the BIOMED SETTINGS
screen is displayed (see Figure 1-2).
Note: The [CHANGE BATTERY] softkey does not appear on earlier versions
of the Plum A+®3.
