Introduction and Start Up
Secondary Infusion (Model 572)
Starting the Pump with Secondary Infusion
1. Load the primed set. See 'Loading the IV Infusion Set' earlier in this
chapter for instructions.
2. Prepare the secondary infusion using a secondary solution container
and the IVAC® "52" Series back check valve set; lower the primary
container. See Figure 1-3 below.
Prime the secondary IV infusion set in accordance with the set
Directions for Use
Attach a secondary IV infusion set to the upper Y-site of the
primary IV infusion set
3. Press the ON/OFF switch to power on the pump. Pump always starts
up in PRIMARY mode.
4. Use the JK switches to set the primary rate.
5. Press VOL TO BE INF if required.
6. Set primary VTBI if required.
7. Press the SEC switch to place the pump into SECONDARY mode. The
pump will sound a four beep verification tone.
8. Use the JK switches to set the secondary rate.
9. Press the VOL TO BE INF switch.
10. Set secondary VTBI by using the JK switches.
11. Press RUN/HOLD to start secondary infusion.
WARNING:
Secondary infusion applications using a back check
valve set must have a VTBI setting equal to the
volume in the secondary container; this will require
consideration of such variables as factory overfill,
medication additions, priming volume, etc.
Underestimating the volume will cause remaining
secondary solution to be infused at the primary rate;
overestimating will result in primary solution being
infused at the secondary rate.
Introduction
This mode of operation supports automatic secondary infusions ("piggybacking") in the same pump channel. When
the secondary VTBI reaches zero, a transition tone will sound and the primary settings will automatically take effect.
Secondary mode can be used where a second, independent VTBI is required, and also when an automatic rate change is
required.
When the pump is programmed and delivering in the secondary mode, the primary infusion is temporarily stopped and
fluid is drawn from the secondary (higher) container. Delivery from the primary container resumes when the fluid level in
the secondary line is level with the fluid in the primary container.
Notes:
1) The primary fluid container must hang lower than the secondary fluid container to allow the secondary infusion to
run.
2) On completion of the secondary infusion the pump will automatically return to primary infusion.
When using a flow sensor it must be positioned on the
primary IV infusion set (as shown in Figure 1-4). Correct
placement of a flow sensor is essential for proper
operation.

Configuration & Calibration
Calibration Procedures (continued)
Dry Set Pressure Calibration (Test 13)
Equipment required:
 Test jumper cable (142109)
 Pressure gauge
 "52" Series IV infusion set (dry set)
Procedure:
1. Remove the chassis from the body. See Chapter 6, 'Spare Parts Procedures' for instructions.
2. Attach the jumper of the test jumper cable between connector J7 on the Logic Board and connector P7 on the
Accessory Interface Board.
3. Connect the battery pack to the battery connector.
4. Set up equipment as shown below.
Note: Set the pressure unit selector switch (on the back panel of the pump) to the same units as the air pressure
source.
5. Enter self-test mode, press the RUN/HOLD switch and select test 12. Press the RUN/HOLD switch again to display the
pressure MMHG (or CMH20).
Ensure the pump is connected to the AC power supply for approximately 30 minutes before continuing with this
calibration.
6. Enter self-test mode, press the RUN/HOLD switch and select test 13. Press the RUN/HOLD switch again to display
PRES CAL.
7. With the door open and no set loaded, adjust the zero potentiometer (R20 on the Analog Board) so the pump reads
000 ±1 mmHg (or 000 ±1.4 cmH20).
8. Install an IV infusion set, close the door and apply a test pressure of 000 mmHg (000 cmH2O) to the distal end of the
set. Record the reading displayed as the PI offset value.
9. Apply a test pressure until the meter reads 400 mmHg (544 cmH2O) and adjust the span potentiometer (R23 on the
Analog Board) so the pump reads 400 mmHg ±2 (544 cmH20 ±10 ) plus the offset value, PI, recorded in the previous
Step.
10. Return the test pressure to 000 mmHg (000 cmH2O), bleed off any air from the IV infusion set then remove the IV
infusion set.
Note: If the set is removed when still under pressure may result in damage to the pressure sensing disc film.
11. Leave the door open and reverify that the pump reads 000 ±1 mmHg (000 ±1.4 cmH2O). If not, repeat the procedure
from Step 7, until no further adjustment of the zero and span potentiometers is required.

Dry Set Pressure Calibration (Test 13) continued
12. Press the Junit and RATE switches simultaneously for a minimum of one second to set the 000 mmHg (000 cmH2O)
calibration point.
13. Reload the IV infusion set and apply test pressure until the meter reads 400 mmHg (544 cmH2O). When the pressure
reading is stable, press the TOT VOL INF and the J100 switches simultaneously for a minimum of one second to set
the 400 mmHg (544 cmH2O) calibration point.
14. Press the RUN/HOLD switch to return to test 13 and turn the pump OFF. Remove the IV infusion set (first bleeding off
any pressure).
15. Disconnect the battery pack from the battery connector.
16. Remove the test jumper cable and reassemble the pump.
17. Perform the 'Dry Set Pressure Verification' procedure as detailed in Chapter 3, 'Routine Maintenance'.
Calibration Procedures (continued)
Both Steps 12 and 13 must be performed to correctly set the calibration parameters. Performing
only one step will result in the message RECONFIG REQD when the pump returns to operation.

Rate Accuracy Calibration (Test 8)
There are two types of rate accuracy associated with the pump, these are System Rate Accuracy and Pump Rate Accuracy.
System Rate Accuracy is the rate accuracy of the pump when used with a standard "52" Series infusion set. Due to slight
variations in between sets, the system accuracy of the pump is ± 5%. Pump Rate Accuracy is the absolute rate accuracy of
an individual pump which can only be determined with the use of a characterised set.
The following procedure describes how to calibrate the Pump Rate Accuracy. For instructions on how to verify Pump Rate
Accuracy, see 'Rate Accuracy Verification' in Chapter 3, 'Routine Maintenance'.
Equipment required:
 Characterized set (191806)
 Stopwatch
 Class A burette (50 ml) with 0.1 ml
graduations
Preparation:
1. Set up the equipment as shown.
 The vertical distance from the
fluid level of the container to
the pump pressure transducer
should be 34 ±4 inches
 The burette zero line should
be within ± 2 inches from the
pump pressure transducer.
Verify that the inside of the
wall is free of droplets
 Ensure fittings are secure and
there is no leakage through
the 3-way stopcock
 Ensure that the air has been
purged from the characterised
set and all equipment
2. Close the set roller clamp.
3. Plug the pump into the AC mains
and turn the pump ON.
Characterised Sets (part number 191806)
 Must be used for rate accuracy calibration
 Sets are labeled with a serial number, a nominal volume and an expiry date (180 days from the date
the set was characterised)
 Handle sets with care at all times. Sets must not be pressurised. Prior to loading or removing from
the pump, manually open the auto-pinch-off mechanism. Do not stretch the set excessively
 Record the number of times each set is used in a log book. A set must not be used for more than 20
rate runs.
