Warnings and Cautions
Warnings tell you about dangerous
conditions, that could lead to death or
serious injury to the user or patient, that
can occur if you do not obey all of the
instructions in this manual.
1. WARNING:You should ensure that the
performance offered by the pump is fit for the
intended purpose. Failure to do so may result
in compromised function of the product,
patient injury or user injury.
2. WARNING: Do not use a faulty pump. If the
pump detects a fault when it is first turned on,
or if it develops a fault during operation then a
continuous system alarm sounds.The pump
must be referred to a suitably qualified
technician or returned to Smiths Medical in
order to have the fault rectified.
3. WARNING: Before using the pump, it should be
inspected for physical damage.The pump
should not be used if damage is evident, and
should be returned to service personnel for
repair before being returned to use. Failure to
do so may result in compromised function of
the product, patient injury or user injury.
4. WARNING: Do not use the pump if you detect
any cracks, chips and loose or bent parts, or
if the buttons do not move in and out freely
when they are pressed. Failure to do so could
cause inadvertent disconnection of the pumps.
5. WARNING:To avoid possible malfunction of the
pump, do not expose the pump to X- rays,
gamma rays or ionizing radiation, or to the RF
interference or strong electric/magnetic fields
emitted (for example) by diathermy equipment
or mobile telephones. If the pump is used in
the presence of, or in combination with
Magnetic Resonance Imaging (MRI) machines
it must be protected from the magnetic field
emitted by such equipment. Malfunction of the
pump can cause incorrect infusion or loss of
infusion resulting in patient injury or death.
6. WARNING: Do not push or pull on the pumps,
or the IV pole may tip over or the pumps fall
to the floor. Do not try to remove modular
connected pumps from the IV pole whilst they
are joined together. Either of these could
cause the administration set to separate from
the fluid container thus spilling the
medication, or the pumps themselves could be
damaged.
7. WARNING: Correct entry of data is essential in
order to ensure that the intended infusion is
performed. Before confirming any displayed
data when setting up an infusion, you should
ensure that it is correct. Failure to do so may
result in compromised function of the product,
patient injury or user injury.
8. WARNING: Dose-rate calculation requires
care in entering data. Refer to specific product
drug labelling for information on appropriate
administration techniques and dosages.
Entering incorrect data may result in patient
injury or death.
9. WARNING:When delivering drugs in the
epidural space, use only those medications
specifically indicated for epidural use.
Epidural administration of other drugs could
result in serious patient injury or death.
10. WARNING:The use of administration sets
incorporating injection sites could lead to an
improper or inappropriate infusion resulting in
serious patient injury or death.
11. WARNING: Failure to clearly identify the pump
and administration sets could lead to an
improper or inappropriate infusion resulting in
serious patient injury or death.
12. WARNING: Remove any air to prevent air
embolism.The presence of air within the
infusion can result in complications resulting
in patient injury or death.
13. WARNING: To avoid over infusion, do not
prime the infusion line when the admini-
stration set is connected to the patient. Over
infusion can result in patient injury or death.
14. WARNING:The Occlusion alarm level must be
checked before starting an infusion to ensure
that it is appropriate for the infusion. Failure
to do so may result in an unacceptably slow
time to Occlusion alarm, resulting in patient
injury or death.
15. WARNING: Prior to starting an infusion,
inspect the fluid path for a closed clamp or
any other obstructions or restriction. Failure
to do so may result in the infusion not being
delivered correctly, resulting in patient injury
or death.
16. WARNING: If using a blood pressure cuff above
the patient’s venipuncture site take extra care
in setting the Occlusion alarm pressures.
Failure to do so may result in unnecessary
Occlusion alarms, resulting in patient injury
or death.
Warnings

Volumetric Infusion Pumps
Warnings and Cautions
Smiths Medical
17. WARNING:The Occlusion detection system
measures downline pressure in the admini-
stration set, but does not detect infiltration. In
accordance with local protocol, you must
periodically inspect the patient’s infusion site
for signs of infiltration. Failure to do so may
result in an unacceptably slow time to
Occlusion resulting in patient injury or death.
18. WARNING: If an Occlusion alarm occurs,
immediately clamp the line to the patient. Then
inspect the fluid pathway to determine what
has caused the obstruction. An unintentional
bolus of medication can result in patient injury
or death.
19. WARNING: Do not run parallel infusion lines
below the pump. Delivering a Secondary
infusion means running a second line
above
the pump. Failure to do so may result in an
inaccurate delivery of medication, resulting in
patient injury or death.
20. WARNING: Check the Secondary set carefully,
since an occlusion above the pump on the
Secondary line could cause the Primary fluid
to be delivered instead of the Secondary
infusion. Administering the wrong medication
may cause serious patient injury or death.
21. WARNING:The Secondary volume to be infused
must match the amount of fluid in the
secondary container. Primary flow resumes
when the secondary container is empty. If the
volumes do not correspond, the wrong infusion
may be delivered which could cause serious
patient injury or death.
22. WARNING: Delivery rate for secondary
medication must not exceed 300 ml/hr, or fluid
may be delivered from both primary and
secondary container causing delayed delivery
of secondary medication and unintended
mixing of fluids. Failure to do so may result in
patient injury or death.
23. WARNING: Correct management of battery
charging, as described in this documentation
is essential to ensure that the pump can
operate on battery for the time specified.
Failure to do so may result in compromised
function of the product or patient injury.
24. WARNING: If a backup alarm sounds, the pump
should be immediately removed from the
patient and sent to be repaired by a Smiths
Medical qualified technician. Failure to do so
may cause patient injury or death.
25. WARNING: Failure to use the power cord
retainer means that the pump may be
accidentally or erroneously disconnected from
the mains. Although there is a battery backup
in case this happens, the battery may not be
charged sufficiently. Consequently, there is a
risk of the pump not functioning which could
lead to patient injury or death.
26. WARNING: Do not open the pump housing.
Refer all service faults only to qualified
technical personnel. Opening the pump
housing may cause electric shock leading to
patient or user injury or death.
27. WARNING:When the pump is carrying out an
infusion, to ensure that electrical safety is
maintained, only items of equipment that
conform to EN60950 are to be connected to the
RS232 connector situated at the back of the
pump, otherwise patient safety may be
compromised.
28. WARNING:While Smiths Medical have taken
all reasonable steps to ensure that the pump
operates correctly while under remote control,
it is the responsibility of the person who
designs and implements the controlling device
to ensure that the resulting system (pump and
controlling device) is fit for its intended
purpose. Failure to do so may result in
compromised function of the product, patient
injury or user injury.
29. WARNING: Use only Smiths Medical
administration sets with this product. Failure
to do so may result in compromised system
accuracy leading to complications resulting in
patient injury or death.
30. WARNING: Ensure that there is no clamp or
other obstruction in the administration set
above the pump. If the line is obstructed, there
will be no flow of fluid and air back to the
Primary fluid reservoir. In this case the pump
cannot eliminate the air from the line above
the pump and a pressure build-up may cause
fluid leakage. Failure to observe this warning
could lead to serious injury or death.

Functional inspections and tests
Perform the following tasks when you
have taken the pump out of the
packaging or when following the regular
testing described on page 9.
As you remove the parts from the
packaging, check that the parts match
the description on page 2.
Visual check
Check for damage:
• check for marks on the pump or
other signs of mechanical damage;
• check the appearance of the LCD
screen for damage, when the pump
is switched off;
• check the serial number and the
label as described on page 3.
If you are carrying out routine
functional checking, repair or replace
any parts that are damaged.
Additionally, check for:
• chipping or cracking of the housing
and the modular connector system;
• proper movement of the mechanical
parts;
• damage to the sleeve or plug on the
AC power cord;
• check that the AC power cord
retainer is fitted to prevent the cord
from being pulled out of the IEC
socket.
Power up and self test
Test that the pump is functioning
correctly.

Further testing
The above tests are basic tests and are
a subset of the acceptance tests
described in the Service Manual. Carry
out further tests as required by your
internal acceptance protocol.
Instrument Care
Periodic cleaning of the pump housing
and inside surface of the door is
recommended. Unplug the power cord

Technical User Manual Smiths Medical
Setting up
Battery charging
Before using the pump for clinical use,
connect the power cord to the AC mains
supply and charge for at least 10 hours.
Pump configuration
With version 0.71 of the pump
software, additional features can be
configured. The complete list of
parameters is shown in the table on
page 12. The features which are
enabled when the pump leaves the
factory are the same as the ones
enabled on previous versions of the
pump. This allows you to run the pump
as if it had been delivered from the
factory as a previous version, without
having to configure it.
When you have carried out the tests on
pages 4 to 7, if you decide to use
additional features, the pump must be
configured. See the description of the
Technician menu on page 12 for details
of how to enable and disable features
as required.
You may also need to set the date and
time using the Service Functions menu
as described on page 20.
Deciding on the configuration
In most cases, your hospital’s protocol
will have been agreed for the
configuration settings for the use of the
pump in particular locations.
When deciding on features to enable,
bear in mind that to have too many
features enabled may confuse the user
and also that with more parameters
enabled, it may take longer to reach the
one required when pressing the
Options key.
Enabling limits
When enabling limits, and deciding on
the protocol to be used, you should be
aware of the following:
• Primary limits can be enabled
independently of Secondary limits;
this is because rates for Secondary/
Bolus infusions may need to be
higher than Primary limits;
• if limits are enabled, you should
ensure that the clinical protocol
includes checking and/or amending
the values for the minimum and
maximum rate and maximum VTBI
limits using the Options key;
• if limits are enabled, the limits
remain at the pump default values
as described in the Specification
unless the operator has set limits
using the Options key;
• if limits are not enabled, then the
pump VTBI/rate limits are as
described in the Specification; the
operator cannot alter them;
• only Primary limits are displayed
during power up, even if both
primary and secondary limits are
enabled;
You cannot disable the ability to give a
Secondary infusion, although you can
disable the Bolus feature.
However, if Secondary infusions are not
used in a particular environment, you
could enable the Secondary limits on
the Technician Menu and then set the
Secondary max rate limit to 1mL/h.
You cannot set a maximum of zero, but
setting the lowest possible maximum
can reduce the risk of a Secondary
infusion being given.

Technical User Manual Smiths Medical
Menus
There are several menus on the pump,
some of which have an overlap of
features. This is to keep backwards
compatibility with pump software
versions before version 0.71.
Users familiar with previous versions
of the pump software can continue to
use a familiar menu to set up the
features of pump that existed before
version 0.71.
Which version of software is in the
pump?
You know that a pump has version 0.71
software (or later), if:
• the Secondary infusion key appears
as:
• the label on the right hand side of
the pump, as shown on page 4, lists
more than eight options;
• the Biomedical menu (menu item
number 9) shows V0.71, for
example:
TheTechnician menu
This menu is only present on pumps
with version 0.71 software and later.
You use the Technician menu to enable
the features of the pump that have
been introduced with version 0.71
software, as well as the features that
existed in earlier versions. These
features and their defaults are
described on page 13.
The Biomedical menu
This menu is the one that also exists in
versions of the pump before version
0.71. In previous documentation it has
also been called the “Biomedical
Special Functions”. As well as enabling
or disabling features, it also displays
data for fault finding and calibration.
Parameters on two menus
The common parameters on both the
Technician and Biomedical menus are:
• Rate Taper
• Volume Over Time
• Dose Rate Calculation.
Which menu should you use?
For the parameters that are on both
Technician and Biomedical menus, you
can use either menu. In most instances,
however,you will:
• use the Technician menu, where
parameters for all the features
appear, to configure the pump for
the user;
• use the Biomedical menu only when
you are servicing the pump.
The Service Functions menu
This menu contains a number of
functions for servicing the pump. It is
also where you set the time in the
pump.
The Special Functions menu
This menu is used to initialise the
pump when it is upgraded. A
description of its use is included in the
Service Manual and the Instruction
Worksheet for the 500/3000 Volumetric
Infusion Pump Software Upgrade Kit.

can continue to move through the list by
continuing to press the Options key
and the first item appears again when
you reach the end. You may find it
faster to switch off and start again.
To move through the list quickly, and
avoid going past the item you want, you
may also find it faster to count the
number of times you press the Options
key. The table on the next page has
been numbered to help you do this.
