The IVAC® Volumetric Pump - Models 571 and 572 automatically regulates the infusion rate of IV solutions using a linear
peristaltic, volume displacement mechanism to regulate fluid flow at the prescribed rate. The pump can be operated with
a Flow Sensor and is compact and robust enough for most patient situations.
The IVAC® 571 Volumetric Pump operates in primary infusion mode only.
The IVAC® 572 Volumetric Pump has a primary and secondary infusion mode.

removed. Refer all servicing to qualified service personnel.
This pump is protected against the effects of radio frequency emissions and is designed to be
M
fail safe if extremely high levels of interference are encountered. Should false alarm conditions
be encountered, either remove the source of the interference or regulate the infusion by another
appropriate means.
If the pump is dropped, subjected to excessive moisture, humidity or high temperature, or otherwise
suspected to have been damaged, remove it from service for inspection by qualified service
personnel.
Introduction and Start Up
When connected to an external power source, a three-wire (Live, Neutral, Earth) supply must be
used. If the integrity of the external protective conductor in the installation or its arrangement is in
d
doubt, the pump should be operated from the battery.
The English switch panel controls and indicators are described below. For information on overlays in other languages,
refer to the relevant DFU. See also Appendix B, 'Spare Parts Listing' for switch panel part numbers.

Operating on Battery Power
The pump operates on battery power when it is disconnected from the AC power. The battery power indicator, the
Information and Numeric Displays will flash whenever the pump is on battery power. In the event of a power failure, the
pump will automatically continue to operate on battery power.
Two alarms indicate the condition of the pump's battery:
LOW BATT alternating with the selected volume or pressure status. This indicates that approximately 30 minutes of
operating time remains on battery power
LOW BATT (constant). This indicates that the battery is discharged. Connect the pump to an AC power supply to
recharge the battery.
Note: The pump's battery is designed for limited duration use. Wherever possible, the pump should be used connected
to an AC power supply. If the pump is to be taken out of service for an extended period, it is good practice to charge the
battery periodically to ensure full capacity.
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.

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.
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.
Verifying a value in one mode while operating in another
1. Press and release the appropriate (current) mode switch. For example, SEC.
2. Within two seconds press the switch representing the information to be displayed. For example, PRI.
Changing the infusion manually to primary mode
1. Press the RUN/HOLD switch to set pump on hold.
2. Press the PRI switch; pump sounds a three beep verification tone and goes into PRIMARY mode.
Flow Sensor
A flow sensor (part number 180) is used to detect an empty solution container. It is connected to the drip chamber and
when a drop is detected in the drip chamber an illuminated ("0") appears in the Information Display.
When not in use, the flow sensor can be stored on the pump handle.
Pole Clamp Accessories
The following pole clamp accessories allow the pump to be mounted on conventional IV poles:
Universal Pole Adapter (part number 6767)
Pole Adapter (part number 5767A)*
Pole Clamp Accessory (part number BC100A)*
* must be used in conjunction with each other.
Refer to Chapter 6, 'Spare Parts Replacement Procedures' for assembly information.

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'.
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.

Vacuum Retention Verification (Test 27)
The pump's vacuum system can be tested and verified by performing the following Vacuum Leak Test.
Procedure:
1. Enter self-test mode and select test 27. Press the RUN/HOLD switch to enter the Vacuum Display mode and display
VAC MMHG.
2. Load an IV infusion set and close the door.
3. Verify that the numeric display shows a reading of -250 or more negative.
4. Allow the reading to stabilise for 5 to 10 seconds, then record the value, for example, -337.
5. After 30 seconds, verify that the vacuum value has not decreased by more than 5, for example -332.
If the pump fails this test:
Check the following things, replacing and repeating the test as necessary:
Face of the pressure transducer
Replace the test IV infusion set
Y-clip, door latch pin, door latch
Pressure transducer/vacuum assembly
Perform the 'Vacuum System Calibration' procedure, see Chapter 2. for instructions.
Without an IV infusion set loaded, turn the pump ON, set rate to 125 ml/h then press the RUN/HOLD switch.
Verify that the LOAD SET message is displayed.
With the pump running, open the door. Verify that the pump stops, alarms and the message DOOR is
displayed. Verify that the automatic pinch-off clamp has stopped the flow by checking that no drops are
falling in the drip chamber.
Load a fluid-filled IV infusion set. Turn the pump ON, set rate to 125 ml/h then press the RUN/HOLD switch
to start infusing. Tilt the drip chamber of the set to induce air bubbles into the IV infusion set. Verify that
when the air bubble enters the pump, the pump alarms, stops and displays the message AIR IN LINE. Turn
the pump OFF and remove the test loop.
Load an empty, air-filled IV infusion set. Turn the pump ON then press the RUN/HOLD switch to start the
pump. The pump should not run; verify that the AIR IN LINE message is displayed. If the pump does run,
refer to Chapter 4, 'Troubleshooting'.
Block the light in the flow sensor (with a finger or other suitable object) to simulate a faulty flow sensor.
Press the RUN/HOLD switch to resume infusing. After a short time, verify that the pump stops, alarms and
the display message alternates between FLOW and SENSOR.
Press the RUN/HOLD switch to place the pump on hold. Hold the VOL TO BE INF switch and press the K
unit switch until OFF is displayed. Press the RUN/HOLD switch to start the infusion. After approximately one
minute, close the roller clamp. Verify that the pump stops running, the alarm tone sounds and the display
message alternates between BOTTLE and CLAMP.
Press the RUN/HOLD switch to place the pump on hold. Set VTBI to 60 ml by first pressing the VOL TO BE INF switch then the
infusing. After approximately one minute, close the roller clamp to create an upstream occlusion.
Verify that the pump stops running, alarms and displays UPSTREAM OCCLUSION.

Battery Power Check and Operation Test
Before performing this test, it is recommended that the battery is charged to full capacity by
connecting the pump to AC mains for a minimum of 16 hours.
1. Remove power cord from the AC power socket.
2. Press the ON/OFF switch to turn the pump on. Verify that the battery indicator flashes on and off.
3. Set rate to 499 ml/h then press the RUN/HOLD switch to start the pump. Verify that the pumping indicator bar
appears on the Information Display and that it rotates rapidly.
4. (Optional) Verify that the pump continues to run for a minimum of 15 minutes without alarming LOW BATT.
5. Plug the power cord back in to AC power socket.
Flow Sensor Check
See 'Physical Inspection and Clean' for instructions.
Take an IV infusion set and cut the tubing a couple of inches below the drip chamber, discarding the drip chamber.
Connect the air pressure source to the freshly cut proximal end of tubing.
Insert the distal end of the modified set into a container of water.
3. Close the roller clamp. Adjust the air pressure to 10 psi.
4. Load the modified IV infusion set. Close the door then open the roller clamp.
5. Open the door and verify that (after an initial spurt of bubbles) no further bubbles are seen coming from the distal
end of the tubing into the water bottle.
If bubbles continue, replace the auto-pinch mechanism. Refer to Chapter 6, 'Spare Parts Replacement Procedures' for
When servicing the pump, the Mechanism Leak Test must be performed to verify the integrity of
the pumping mechanism.
Misalignment of the pumping mechanism can result in the pressure plate and the mechanism's cam
followers failing to pinch the IV infusion set tubing sufficiently, thereby allowing the pump to leak
fluid at low rates or when stopped.
Procedure:
1. Prepare a special Pressure Test Set as follows:
Take an IV infusion set and cut the tubing a couple of inches
below the drip chamber, discarding the drip chamber.
With a knife, carefully remove the membrane cover from the
white pressure sensing disc, see Figure 3-2. Ensure no membrane
(rough edges) remain—the surface of the pressure sensing disc
should be as flat as possible after the membrane is removed.
Cut out a piece of mylar to match the shape and size shown
below.

Remove the adhesive backing and firmly press the mylar onto the
surface of the pressure sensing disc so that it covers the vertical
slot and is centered on the disc. See Figure 3-3
The distal end (bottom) end of the set may be cut to adapt it for
connecting to the air pressure source.
Figure 3-2
Figure 3-3
2. Load the special pressure test set, with 15.0 psi (775 mmHg) air pressure at the distal end, into the pump and close the
door.
Change the special Pressure Test Set after 20 uses, or if signs of wear are visible on the silicone
section or if any leak in the set is observed.
3. Run the top end of the pressure test set into the water bottle and below the water level (as shown below).
4. Open the pressure test roller clamp to pressurise the set.
