IVAC® Volumetric Pump (Models 571 & 572) 5/104 1000SM00018 Issue 2
Introduction and Start Up
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.
Product Familiarity
Ensure that you are fully familiar with the pump by carefully studying the Directions for Use (DFU) prior to operation and
prior to attempting any repairs or servicing. As part of continuous improvement, product enhancements and changes are
introduced from time to time.

Introduction and Start Up
General Precautions
Prior to using this pump, carefully read the Operating Precautions described in the Directions for Use
(DFU).
This pump contains static-sensitive components. Observe strict precautions for the protection of
static sensitive components when attempting to repair and service the pump.
An explosion hazard exists if the pump is used in the presence of flammable anaesthetics. Exercise
care to locate the pump away from any such hazardous sources.
Dangerous Voltage. An electrical shock hazard exists if the casing of the pump is opened or
removed. Refer all servicing to qualified service personnel.
MThis pump is protected against the effects of radio frequency emissions and is designed to be
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.
)6 #
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.
dWhen 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
doubt, the pump should be operated from the battery.

Notes:
1) Without a flow sensor in use, a VTBI value must be entered,
otherwise, the pump will be unable to operate.
2) With a flow sensor in use, a VTBI value isn't required and
OFF can be selected if required.
Programming
Adjusting the maximum pressure limit
(Occlusion pressure alarm level)
1. Simultaneously press and hold the LIMIT PRES
switch whilst using the JK switches to adjust
the pressure limit.
2. Release the LIMIT PRES switch.
Note: Pressure value will be displayed in mmHg or in
cmH20 depending on unit selected. See 'Pressure
Unit Selector'.
Reading the pressure
1. Press and hold the READ PRES switch. Wait at least
10 seconds to allow reading to stabilize.
Note: Pressure value will be displayed in mmHg or
in cmH20 depending on unit selected. See 'Pressure
Unit Selector'.
Selecting alternating display of total
volume infused
1. Press and release the TOT VOL INF switch three
times within 2 seconds while the pump is infusing or
on hold.
On Model 572, the display will alternate between
primary or secondary infusion and total volume
infused.
On Model 571, the display will continuously
show the total volume infused.
Selecting alternating display of infusion
pressure
1. Press and release the READ PRES switch three times
within 2 seconds while the pump is infusing or on
hold.
On Model 572, the display will alternate between
primary or secondary infusion and infusion
pressure.
On Model 571, the display will continuously
show the infusion pressure.
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.
