Warnings
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 Graseby 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: 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.
6. 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.
7. 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.
8. 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.
9. WARNING: The use of administration sets
incorporating injection sites could lead to an
improper or inappropriate infusion resulting in
serious patient injury or death.
10. 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.
11. WARNING: Remove any air to pre vent air
embolism. The presence of air within the
infusion can result in complications resulting
in patient injury or death.
12. WARNING: T o avoid o ver infusion, do not
prime the infusion line when the administration set is connected to the patient. Over
infusion can result in patient injury or death.
13. WARNING: The Occ lusion 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.
14. WARNING: Prior to starting an infusion,
inspect the fluid path for kinks, a closed clamp
or other obstructions. Failure to do so may
result in the infusion not being delivered
correctly, resulting in patient injury or death.
15. 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.
16. WARNING: The Occ lusion detection system
measures downline pressure in the administration 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.
17. 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.
Volumetric Infusion Pumps
Warnings and Cautions
Graseby Medical Ltd.
18. WARNING: Do not run parallel infusion lines
below the pump. Delivering a Secondary
infusion means running a second line
the pump. Failure to do so may result in an
inaccurate delivery of medication, resulting in
patient injury or death.
19. WARNING: Chec k 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.
20. 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.
21. 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.
22. WARNING: If a bac kup alarm sounds, the pump
should be immediately removed from the
patient and sent to be repaired by a Graseby
Medical qualified technician. Failure to do so
may cause patient injury or death.
23. WARNING: F ailure to use the power cord
retainer means that the pump may be
accidentally or erroneously disconnected from
above
the mains. Although there is a battery backup
in case this happens, the battery may not be
charged sufficiently . Consequentl y , there is a
risk of the pump not functioning which could
lead to patient injury or death.
24. 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.
25. 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.
26. WARNING: While Graseb y Medical Limited
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.
27. WARNING: Use onl y Graseby 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.

New features of version 0.71 software
The information in this section is
intended for technicians and clinicians
already familiar with earlier versions
of the Graseby 500/505 volumetric
pump. It summarises the changes to
the pump that appear with version 0.71
of the pump software:
• new menu,
• new options,
• new features that the menu and
options provide.
To find out the software version of a
particular pump, check the instructions
label on the right side of the pump. If
there are more than eight options
listed, then the software version is 0.71
or later.
For full details on how to use the pump
see the Volumetric Instruction Manual.
For information on configuring the
pump, see the Technical User Manual,
and for more detailed technical
information, obtain a copy of the
Volumetric Service Manual.
New Menu
A Technician Menu has been introduced,
to simplify the configuration of each
pump. Some of the items on the
Technician Menu affect how the pump
behaves; others control the options that
appear to the pump user when they
press the Options button to show the
Options menu. The configurable items
on the new Technician Menu are shown
on page 12 of the Technical User
Manual.
If the Technician Menu settings are left
at their factory defaults, the pump
behaves as the previous version of the
pump.
New Options
The new options (and some of the
previous options) can be enabled on the
Technician Menu. This means that they
can appear when appropriate, but can
be disabled if not required. On the
instruction label on the pump, Options
numbered 1 to 8 are the ones that
appeared in previous versions of the
pump software. The additional new
options shown on the label are:
• Primary infusion Minimum
• Primary infusion Maximum
• Primary Max Volume to be infused
• Secondary/Bolus Minimum
• Secondary/Bolus Maximum
• Secondary/Bolus Max Volume to be
infused
• KVO Rate
• Drug Library to allow selection and
display of a drug label.
New features
The new menu and new options in
version 0.71 software provide a number
of new features. These fall into the
following broad areas:
• Infusion mode features
• Safety features
• Display features
• Servicing features.
Infusion mode features
Using the Technician Menu, the pump
can be configured:
• to stop at the end of a Secondary
infusion, or to continue infusing and
automatically switch to the
programmed Primary rate;
Volumetric Infusion Pump Instruction Manual
v
Contents
Graseby Medical Ltd.
• to allow a Bolus infusion to be
programmed where the volume
infused is deducted from the
primary infusion volume to be
infused; to highlight this feature,
the key previously called
“Secondary” is now called
“Secondary/Bolus”
• to allow the user to set a KVO rate
for an infusion, or remain at the
default rate configured for the
particular pump;
• to use the Occlusion Alarm level
specified for an infusion, or remain
at the configured default alarm
level;
• to allow access to a previously
programmed Dose-Rate Calculation
infusion when the pump is switched
on (Dose-Rate Calculation recovery),
or display the standard messages.
Safety features
• a timeout safety feature has been
added. This means that when
messages are not actioned within
the timeout period, for example
setting a value, the pump reverts to
the previous display.
• safety keypad lockout, this feature
is only activated when operating the
pump on AC power. It allows the
user to lockout the keypad after
setting the pump up for use, so that
it can be ready for infusion at a
later time.
Configurable safety features that can be
controlled on the Technician Menu are:
• automatic keypad lock after one
minute, to prevent malicious
tampering, and increase patient
safety;
• preset rate and VTBI limits, so that
Infusion Rate and Volume to be
Infused are limited to a suitable
range; this prevents values being
programmed accidentally which are
inappropriate for infusions in
particular environments (such as
epidural infusions, or paediatric
applications).
Display features
• configured parameters are shown on
the Message Display when the pump
is switched on.
Configurable display features that can be
controlled on the Technician Menu are:
• the backlight may be activated when
the keypad is touched, or kept on
permanently;
• one of 30 preset drug labels may be
selected and viewed as required
during an infusion;
• the display of micrograms (when
programming an infusion using
dose-rate calculation) can be shown
as ‘µg’ or ‘mcg’;
• the time display may include the
suffix GMT, or the suffix can be
suppressed if it is not appropriate.
Servicing features
On the Technician Menu, the pump can
be programmed with a pump ID to suit
the hospital protocol, and a service due
date:
• the ID, for example the serial
number of the pump, or an
alphanumeric pump name, is
displayed each time the pump is
turned on;
• when a Service Date is set, the date
is displayed each time the pump is
switched on. An alarm sounds when
the date is reached.

Introduction
Introduction to the 500/505 pumps
The Graseby Medical 500 and 505
Volumetric pumps are designed for use
in infusion therapy in both venous and
arterial infusions. They offer both
standard and optional features
bringing accurate fluid delivery to the
patient.
This makes them ideal for use in
general care, home care, and intensive/
critical care areas.
The Model 500 and Micro 505 pumps
are very similar in design. The
differences are in colour, graphics and
in the maximum rate and volume to be
infused that can be programmed for an
infusion.
The main features of the pumps are
described starting on page 1-3. For full
details on the differences between the
500 and 505, see the Specification
section at the end of this manual.
Read the entire contents of this
manual carefully before using the
pump.
Model 500 Volumetric pump
The Model 500 is designed for use in all
areas, as it can be programmed with an
infusion rate of up to 999 millilitres per
hour, and a maximum volume to be
infused of 9999 millilitres.
Micro 505 Volumetric pump
The Micro 505 is designed for use in
paediatric/neonatal environments and
for fluid restricted patients. It can only
be programmed with an infusion rate
below 100 millilitres per hour, and the
maximum volume to be infused is 999.9
millilitres.

Introduction
Epidural administration
Graseby Medical Ltd.
Both the Model 500 and the Micro
505 pumps may be used for epidural
administration.
Anaesthetics
Epidural administration of
anaesthetics is limited to short-term
(not to exceed 96 hours) infusion, with
indwelling catheters specifically
indicated for short-term delivery of
anaesthetic drugs.
Analgesics
Epidural administration of analgesics
is limited to use with indwelling
catheters that are specifically indicated
for short or long term delivery of
analgesic drugs.
To prevent infusion of drugs not
indicated for epidural use and to avoid
inappropriate delivery rates when
using the pump for epidural
applications:
• use the pump’s Maximum Rate
option, to set a maximum infusion
rate of 20 mL/h on a pump to be
used for epidural administration.
This feature is described fully in
Chapter 3, Options;
• do not use IV administration sets
which contain injection sites;
• differentiate the pump and IV set
being used for epidural delivery from
those being used for other routes of
administration. A yellow Epidural
Label Set for the Volumetric
Infusion Pump (part number TPF-
00306) is available from Graseby
Medical. The labels should be stuck
on the front, top and sides of the
pump to help staff to identify a
pump that is dedicated to epidural
application.
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.

Pump features
Introduction
The main features of the 500 and 505
pumps are listed below:
Easy to use features
The pumps have been designed to be
easy to use:
• they are easy to set up and operate,
yet with all the advanced features
typically associated with the more
complicated infusion systems;
• they have a straightforward keypad
and an easy-to-read message display;
• the unique air-in-line removal
system allows clearing of bubbles in
the line by simply opening and
closing the door: air is prevented
from going beyond the cassette; this
increases patient safety, minimises
the risk of infection and saves
operator time;
• they can be used at the bedside or as
transportable equipment; using the
internal battery which also switches
in automatically if the pump is
being used on mains power and this
is interrupted.
Use of administration sets
The pumps can only be used with
Graseby Medical administration sets.
These administration sets have the
following features:
• all Graseby Medical administration
sets incorporate a safety clip to
prevent accidental free flow when
the administration set is removed
from the pump;
• when used with Graseby Medical
blood administration sets the
pumps deliver blood and blood
products without significant
haemolysis of red blood cells.
Infusion mode features
• accurate (± 2%) fluid delivery;
• the pumps can be configured to stop
at the end of a Secondary infusion,
or automatically switch to infuse at
the programmed Primary rate;
• a Bolus infusion may be
programmed so that the volume
infused is deducted from the
primary infusion volume to be
infused;
• KVO rate may be specified for an
infusion, or remain at the default
rate for a particular pump;
• the pumps offer a quick rate change
feature for complete titration
capability;
• automatic delivery of a secondary
medication (if a secondary infusion
has been set up).
Safety features
The pumps have been designed with a
high emphasis on safety:
• there is an optional automatic
keypad lock which prevents
inadvertent operation and increases
patient safety;
• the keypad can also be locked
manually at any time;
• a pump may be configured so that
its Infusion Rate and Volume to be
Infused are limited to a suitable
range; this prevents values being
entered accidentally which are
inappropriate for infusions in
particular environments (such as
epidural infusions).
• the pumps have indicators that are
lit to show if they are running on
battery or mains;

Introduction
Graseby Medical Ltd.
• when using the battery, a test is
performed on power-up and the level
is shown on the display; manual
testing is also available;
• the pumps have an RS232 interface
allowing connection to a computer
for external monitoring.
Display features
Apart from the standard display,
pumps can be configured to show extra
information, either as a standard
message display or by pressing a key to
toggle the display.
Standard displays are:
• the volume infused in the current
infusion;
• the infusion rate;
• the Volume to be Infused in the
remainder of the infusion.
Additionally:
• the rate and volume to be infused
displays are automatically adjusted
to make them easy to read in any
light;
• the time remaining in the present
infusion may be viewed;
• the total volume of fluid delivered to
your patient since the totaliser was
last cleared to be viewed; also
displayed with the total volume is
the total time (hours and minutes)
that the pump has been in use since
the totaliser was last cleared;
Using configurable displays:
• the backlight may be activated when
the keypad is touched, or kept on
permanently;
• optionally, one of 30 preset drug
labels may be selected and viewed
as required during an infusion.
Occlusion Pressure features
These features increase safety in
infusing fluid, particularly in critical
care areas such as neonatal and
paediatric care:
• when setting occlusion alarms, three
standard occlusion alarm settings
between 100 and 500 mmHg can be
made; see the Specification section
at the end of this manual for full
details of the occlusion alarm
values;
• the occlusion pressure alarm setting
when the pump switches on is
configurable; you can change the
setting for a particular infusion
using the Occlusion Alarm
Setting key;
• when an occlusion alarm sounds, the
pumping mechanism backs off to
reduce downline back pressure and
bolus potential (bolus potential is
approximately 0.3 mL regardless of
the rate and the administration set
used);
• when an occlusion is detected, the
pump does not give an occlusion
alarm immediately, but only alarms
if the occlusion pressure continues
to exceed the occlusion threshold for
up to 10 seconds; however, if such
temporary occlusions persist, then
the occlusion alarm is generated;
this helps to avoid nuisance
occlusions.

Introduction
Special infusion features
The pumps have a number of special
infusion options:
• a Volume over time option allows
the user to set the volume to be
infused and total time for the
infusion, the pump automatically
calculating the infusion rate;
• a Dose-rate calculation option which
allows automatic calculation of the
infusion rate by entering infusion
dose; patient weight (kg or lbs); drug
amount in fluid container (in MG,
Gm or mcg units), and volume of
fluid in the container, in mL;
• a Rate Tapering option allows
automatic tapering of the infusion
rate (either up or down) for
administration of IV nutrition.
Multiple use features
When multiple infusion lines are
required, two or three pumps can be
fitted together:
• modular side rails and hooks mean
that one, two, or three pumps may
be connected to a single IV pole; this
provides space saving;
• the modular connection system has
a safety feature which ensures that
the first pump must be correctly
attached to an IV pole before the
second and third pumps can be
connected.
• special menus are provided to aid in
testing, troubleshooting and service;
• the last 200 events are recorded and
available on these menus;
• downloading of the pump history is
possible using the RS232 port with
a special optional kit (Part no 0150-
0673).
Together with the ability to configure
the pump using the Technician Menu,
these features offers greater
management flexibility.
Instructions for using these functions
appear in the Technical User Guide and
the Volumetric Service Manual.
Optional features
Some pumps are optionally fitted with
a Nurse-Call Feature which allows a
pump to be connected to a hospital
nurse call system and signal alarms
occurring in the pump.
Note: This feature is not available in
all countries.
Servicing features
The pumps have been designed with a
number of features for Biomedical
engineers:
• a Service Due Indicator, allows a
service date to be set, which is
displayed on power-up with an
alarm;

Operating the pump
Connecting the pumps to an IV pole
In use, Graseby Medical recommend
that the pump should be connected to a
suitably balanced IV pole using the pole
clamp as illustrated in the diagram on
the opposite page.
The diameter of the pole must be
between 1.2 cm and 3.8 cm (0.5 and 1.5
inches).
To provide maximum stability when
using the modular connection system,
ideally, the IV pole should have 6
wheels and a low centre of gravity. The
base diameter should be 56 cm (22
inches).
Attaching a single pump to an IV
pole
To attach the pump to a suitably
balanced IV pole:
1. Loosen the screw on the pole clamp.
2. Hold the pump by the handle and
slip the arms of the pole clamp onto
the pole.
3. Tighten the screw on the pole clamp
to firmly attach the pump to the
pole.
Attaching more than one pump to
an IV pole
When multiple infusion lines are
required, you can connect up to three
pumps to a single pole using the hooks
and rails that make up the modular
connection system.
As all pumps have connectors on both
sides, you can use any one as the centre,
left, or right pump.
This diagram shows how three pumps
may be connected together using the
Volumetric’s modular connection
system:
Inspecting the modular
connections
Before connecting the pumps, you must
check that the modular connection
parts are all in good condition:
1. Carefully inspect the modular
connection system for damage,
including cracks, chips, loose or bent
parts.
2. Press the disconnect buttons several
times to make certain that the
buttons move in and out freely.
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.

Graseby Medical Ltd.
How to connect pumps together
Once you have inspected the modular
connection system as described in the
previous section, connect the pumps as
follows:
1. Clamp the first pump to the IV pole.
This is now the "centre" pump.
Note: As you tighten the screw on the
pole clamp, you automatically adjust
the modular connection hook and
disconnect button. Once the pump is
securely attached to the pole, the hook is
in the correct position to allow you to
connect further pumps.
2. Take the second pump, grasping it
by the handle and hold it so that the
modular connector rails are directly
above or below the connector rails of
the centre pump.
3. Engage the edges of the modular
connector rails and slide the second
pump up or down until it is
connected to the centre pump. When
the connection is secure, you hear a
distinct click.
4. Before releasing the handle of the
second pump, double-check that the
connection is secure by moving the
pump up and down and exerting
pressure on the top of the pump.
To attach a third pump to the other
side of the first pump, repeat steps 2, 3
and 4.
Note: If the connection is loose, or the
pumps seem to wobble, disconnect
then carefully reconnect them,
making sure both edges of the
modular connectors engage. Do not
use pumps where the connection is
loose, but return them to a suitably
qualified technician for repair.
Moving an IV pole with pumps
connected
If you need to move the IV pole once the
pumps are attached, always ensure
that you grasp the IV pole with one
hand and steady the pumps with the
other hand if necessary.
Disconnecting modular
connected pumps
You must always disconnect modular
connected pumps one by one before
removing the centre mounted pump
from the IV pole.
Disconnect the left and right hand
pumps from the centre mounted pump
as follows:
1. Grasp handle of pump to be
removed.
2. Lift the pump slightly.
3. Press the disconnect button and
slide the pump up or down to
disconnect from the centre pump.
4. Place the pump in a location where
it will not be damaged.
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.

necessary, the pump can be run on its
internal batteries, see Using the pump
on batteries, later in this chapter.
message is displayed and the alarm
sounds. See Chapter 4, Troubleshooting
for more details on handling alarms.
Message Display at Switch on
The messages displayed when you
switch on the pump depend on which
features have been enabled on the
pump and whether or not it is
connected to the AC mains supply.
If all the pump options have been
enabled, the pump displays messages
to provide you with the following
information about itself:
• Pump Identifier
• Drug Label
• Primary Min Rate and Max Rate
• Primary Max VTBI
• Battery gauge (displayed only if the
pump is disconnected from the AC
mains supply)
• Service due date.
After switching on

Operating the pump
Switching off
Graseby Medical Ltd.
For safety reasons, the front door must
be properly closed and any infusion
must be on Hold before you switch off
the pump.
• If the pump is running an infusion,
press the Hold key;
• if the front door of the pump is open,
close it with the latch;
• then press the On/Off key.
Using the pump on battery
The pump contains an internal
rechargeable battery. However, in
everyday use, the pump should be
connected by its cord to a suitable AC
mains supply, if one is available. The
battery is then kept fully charged, and
will continue to be charged whilst the
pump is infusing.
The pump automatically uses the battery:
• if you switch on whilst the power
cord is unplugged, or
• if the AC power fails whilst the
pump is operating.
Switching on using the battery
When you switch on the pump, if it is
being powered by internal battery:
• you need to hold down the On/Off
key to turn the pump on. If the pump
is operating on the AC mains
supply, it switches on
instantaneously when you touch the
On/Off key;
• there is a short pause whilst the
pump carries out the Battery Test
and displays the Battery Gauge
screen to indicate the current
battery capacity:
Note: The battery is always tested
when the pump is switched on, even
though the Battery Gauge is not
displayed during Dose-Rate
Calculation, DRC Recovery or Rate
Taper infusion start up.
Testing the battery
At any time when operating on battery,
you can check the battery capacity by
carrying out the Battery Test described
in Chapter 3, Options.
Operating using the battery
During operation of the pump on
battery:
• the yellow Battery indicator is lit
• the Message Display light turns off
if the pump is left on Hold, unless
you have set the ‘Backlight on’
option, described in Chapter 3,
Options.
Low battery
When you switch on the pump, and
during operation, the pump warns you
when the battery capacity is low. If you
see the yellow Battery indicator
flashing whilst the pump is infusing,
you should plug the power cord into the
AC mains supply as soon as possible.

Graseby Medical Ltd.
Operating the pump
Low battery alarms
When approximately one hour of
operation remains, the pump sounds an
alarm and displays this message:
If you see this message, plug the power
cord into the AC mains supply as soon
as possible.
If you decide that you must continue to
use the pump on battery, another
alarm sounds approximately half an
hour before it is fully discharged.
This message is displayed:
It is essential that the pump is plugged
into the AC mains supply at this point.
Recharging the battery
To charge the battery, plug the power
cord into the AC mains supply.
It takes approximately 10 hours to
recharge a completely depleted battery.
Capacity
A new, fully charged battery will
operate the pump for approximately 6
hours at 100 mL/h (99.9 mL/h on Micro
505).
The battery may discharge more
quickly if the battery has aged and is in
a poor condition even though it was
recently charged.
Pump in storage
You should connect the pump to the AC
mains supply to charge the battery
every three months, even when the
pump is not in service. This helps to
maintain the life of the battery.
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 .

Sounds on the Volumetric
The Volumetric pump makes a 'click'
sound as you press each key. It also
sounds an audio alarm to alert you to a
condition that requires attention on the
pump: either an insistent (three-tone)
or non-insistent (two-tone) alarm. The
click and non-insistent alarm do not
Audio alarm
When the Volumetric pump requires
attention, it uses an audio alarm to
indicate that there is a problem.
Whilst sounding the alarm, it also
displays a message to explain the
problem. A full list of all the alarm
messages, their possible causes and
how to solve the problem is explained
in Chapter 4, Troubleshooting.
This section explains the different
types of alarm sounds made by the
pump.
You may hear three types of alarm from
the Volumetric:
• insistent
• non-insistent
• continuous (backup alarm).
Insistent alarm
This type of alarm indicates that fluid
delivery has stopped, or cannot be
started. It alerts you to a condition that
must be corrected before the infusion
can be started, or continued, for
example if an occlusion is detected.
The insistent audio alarm consists of
three tones: two high-pitched and one
low-pitched, repeated at two-second
intervals.
sound if the pump is switched on in
Quiet Pump mode. See next page. As a
further safety feature, the Volumetric
emits a high-pitched system alarm to
indicate a problem requiring the
attention of a Graseby Medical
qualified technician.
To silence an insistent alarm, press the
Silence or Hold key. The alarm will
recur unless you correct the problem as
described in Chapter 4, Troubleshooting.
This chapter describes each alarm, its
cause and action to take.
Non-insistent alarm
This type of alarm alerts you to a
condition that needs attention, but has
not caused the infusion to stop. For
example, you hear a non-insistent
alarm if the pump is running on
batteries and the batteries are low, or
if the infusion has switched to a KVO
rate.
The non-insistent audio alarm consists
of two tones, one high-pitched and one
low-pitched, repeated at two-second
intervals. To silence this type of alarm:
• press the Silence or Run key to
silence the alarm without stopping
fluid delivery;
• press the Hold key to silence the
alarm and stop fluid delivery.
Note: In Quiet Pump mode, there is no
audio alert for certain non-insistent
alarms. See the next page for more
details.

Volumetric Infusion Pump Instruction Manual
Graseby Medical Ltd.
Operating the pump
Continuous - backup alarm
In addition to the insistent and noninsistent operational alarms, the
Volumetric pump has a fail-safe
backup alarm system. This has a
distinctive high-pitched tone:
• should the audio alarm system fail,
then the pump sounds the backup
alarm, with a 1.5 second pause
between alarm tones;
Quiet Pump mode
In some circumstances, it may be
desirable to operate the Volumetric
without the associated sounds.
For safety reasons, you cannot turn off
the insistent or continuous alarms, but
if necessary you can operate the pump
without the key-press 'click' sound and
certain non-insistent alarms. This is
called a 'Quiet Pump' infusion.
To run a 'Quiet Pump' infusion:
1. Ensure that the pump is turned off.
2. Press Silence and keep it held
down.
3. Turn on the pump with On/Off.
The keypad click and non-insistent
alarm sound is now off. The pump
remains in Quiet Pump mode until you
switch off and then on again.
• should an electromechanical system
failure occur, the pump sounds the
backup alarm continuously.
If you hear the backup alarm sounding,
you should immediately remove the
pump from the patient and have it
repaired by a Graseby Medical
qualified technician.
Silent alarms in Quiet Pump mode
When running the pump in Quiet Pump
mode, certain alarms associated with a
Secondary infusion are silent. The
alarm is silent in the following
circumstances:
• when the pump automatically
switches from Secondary to Primary
when the Secondary infusion is
complete;
• when you program the Secondary
infusion, but press the Primary key
then the Run key without running
the Secondary infusion;
• when you press Run to start the
Secondary infusion with the Volume
to be Infused set to zero.
Alarms and computer control
If a pump is being run under computer
control, you can silence it from the
computer. However, you must resolve
the problem causing the alarm on the
pump.
Volumetric Infusion Pump Instruction Manual
WARNING: If a backup alarm sounds, the
pump should be immediately removed
from the patient and sent to be repaired
by a Graseby Medical qualified technician.
Failure to do so may cause patient injury
or death.

Primary and Secondary
For a Primary and a Secondary
infusion, two containers are used:
• one to deliver the Primary infusion,
for example, a hydration solution;
• a second to deliver an additional
infusion, for example an antibiotic
dose; this is sometimes called a
“piggyback” infusion.
The pump keeps separate totals for the
Primary and Secondary infusions: the
total infused in the Secondary infusion
is not deducted from the Primary
Volume to be Infused.
The pump can be configured to work in
one of two ways at the end of the
Secondary infusion: see Ending a
Secondary infusion, over the page.
For full details on how to set up a
Secondary infusion:

Operating the pump
Primary and Bolus
Graseby Medical Ltd.
With the pump configured to offer the
Bolus feature, you can carry out a Bolus
infusion as an alternative to the
Secondary infusion.
A Bolus infusion may be administered
at a different rate, with the volume to
be infused entered separately to the
Primary volume, just as for a
Secondary infusion.
However, for a Bolus infusion, the
Volume infused is deducted from the
Primary Volume to be Infused.
At the end of the Bolus, the pump
reverts to the Primary infusion at the
previously programmed Primary rate.
The Secondary Stop feature, if enabled
has no effect at the end of a Bolus.
When the Bolus feature is configured,
each time you press the Secondary/
Bolus key, the Message Display shows:
At this point, you would press 3 to
enter Rate and Volume to be Infused
for the Bolus, or to view the totals for
the Bolus infusion.
For full details on how to administer a
bolus infusion, see Running a Bolus
Infusion on page 2-31.
Ending a Secondary infusion
The Secondary Stop feature in the
Technician Menu controls how the
pump works when the Secondary
infusion is complete.
• With Secondary Stop disabled, the
pump automatically reverts to the
Primary infusion at the previously
programmed rate, so that there is a
continuous flow. When the Primary
infusion starts a non-insistent
alarm sounds.
• With Secondary Stop enabled, the
pump stops and sounds an alarm
until you manually silence it and
start the Primary infusion.

The effect of Options settings on
infusions
Some of the Options settings can affect
the way you program the infusion, what
you can do during the infusion, or the
way the pump behaves. For example, if
the pump has the appropriate Options
enabled on the Technician menu, you
may choose to:
• turn on the Message Display
backlight
• set the KVO rate
• select a Drug Label
• program a Dose-Rate Calculation,
Volume Over Time or Rate Taper
infusion.
Infusing with Rate and VTBI limits enabled
However, the settings which may most
affect the way you program an infusion
are Rate and VTBI limits. Such limits
restrict the values you can use during
an infusion and their use is described
below.
If you need to make any changes to
these Options settings, you must do so
before programming the infusion. See
Chapter 3, Options for full details.
If the features for setting limits are
enabled on the Technician Menu, the
limit values can be set or examined
using the Options key. They can be set
independently for Primary and
Secondary infusions and may not all be
enabled. If Primary Rate or VTBI
limits are enabled, you can also see the
settings displayed after the pump is
switched on.
When limits are enabled, you cannot
run an infusion with a Rate or Volume
to be infused set outside the limits.
Also, you cannot change the rate while
running to go outside the limits. If you
try to do this, or if you program a value
outside the limits and then press the
Run key, you see the message:
Volumetric Infusion Pump Instruction Manual
Wherever possible check or set the
limits before you program the infusion,
especially if you might have to give a
Secondary infusion or a Bolus. The
easiest way to check Primary infusion
settings is to look at the message
display when you switch the pump on.
To check Secondary infusion settings,
you must use the Options key. Setting
limits is described in Setting Rate and
VTBI limits on page 3-29 in Chapter 3,
Options.
Limits are enabled and set for a safety
purpose (for example, where the pump
is used for Epidural administration). If
you are likely to be in a situation where
you have to give an infusion in an
emergency, ensure that when a pump is
switched off, the limits are left with
safe value settings.

administration set following the
instructions provided with the set. As a
guide:
1. Remove the solution container from
its packaging and remove the cap
from the fluid outlet.
2. Remove the administration set from
its packaging and close the roller
clamp.
3. Remove the cap from the spike on
the administration set and insert
the spike into the fluid outlet on the
solution container.
4. Hang the container with the
administration set on the IV pole
and ensure that the container is the
correct height above the pump.
• prepare the solution;
• prime the administration set;
• load the administration set into the
pump;
• program the infusion;
• start the infusion.
Height of solution container above
the pump
If necessary, adjust the height of the
pole so that the bottom of the solution
container is between 15 cm and 30 cm
(between 6 inches and 12 inches) above
the top of the pump
On Model 500, 30 cm (12 inches) may be
required for rates over 500 mL/h.
On both Model 500 and Micro 505,
30 cm (12 inches) may be required when
using thick solutions and/or
60 drops/mL sets.
Note: A thick solution in this case may
be certain cytotoxic agents, lipid-based
fluids and other viscous solutions, for
example Total Parenteral Nutrition.
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.

Prime the administration set - Example
You must always follow the Instructions
for Use that accompany the
administration set to be primed. This
section shows an example to explain
the basic priming steps to be carried
out on an administration set without a
bi-directional check valve, filter,
injection site or c-clamp.
1. Squeeze the drip chamber and fill
until it is at least one third full. The
drip chamber may fill completely
during loading and/or an infusion.
This will not adversely affect the
fluid delivery or the operation of the
pump.
2. Hold the cassette inverted, so that
the roller clamp is above the
cassette, as shown here.
3. Slowly open the roller clamp to
allow the solution to flow through
and prime the cassette and the line.
You can control the flow by moving
the roller clamp as necessary.
4. When the entire set is primed, close
the roller clamp.
With the solution container hanging on
the IV pole and the administration set
spike inserted into the container, prime
the administration set as follows:
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.
WARNING: Use only Graseby 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.

Operating the pump
Security on the pump
Graseby Medical Ltd.
To prevent any tampering with the
keypad during the infusion, there are
two ways to secure the keypad:
• manual locking
• automatic locking.
Manual keypad locking
This safety feature is always available
on the pump, whether or not the
automatic keypad locking feature is
enabled.
To lock the keypad during an infusion,
press the grey Keypad lock button on
the rear of the pump. The Message
Display confirms that the keypad is
locked:
If you touch any of the keys on the
keypad once it is locked, the pump redisplays the message.
Safety keypad lockout
The saftey keypad lockout is only active
when operating the pump on AC power.
It allows the user to ‘lockout’ the
keypad, so that after setting up the
pump for use, it is ready for infusion at
a later time.
To set the saftey keypad lockout, switch
the pump off and connect to an AC
power supply. Then press the keypad
lock button once. If you now attempt to
switch the pump on, the keypad is
locked out and the pump inactive. The
pump can only be switched on by:
• pressing the keypad lock once and
then switching the pump on using
the On/Off key
• or by opening the door.
If the AC power supply is removed
during the ‘lockout’, the feature is
abandoned, pressing the On/Off key
switches the pump on. If the AC power
is removed and reconnected without any
user interface with the pump, the
lockout remains active. When the pump
is used on battery power this feature is
inactive.
Automatic keypad locking
Before starting the infusion, you can
enable the Autolock Keypad feature in
the Technician Menu.
With Autolock Keypad enabled, the
keypad locks automatically if you leave
the pump untouched for one minute.
If you touch a key, the Message Display
reminds you that the keypad has been
locked:
Unlocking the keypad
To unlock the keypad once it is locked,
press the grey Keypad lock button on the
rear of the pump:
• for a manually locked keypad, press
the button once;
• for an automatically locked keypad,
press the button twice.

Display the Drug Label
Operating the pump
The pump may be configured, in the
Technician Menu, to display the Drug
List.
If the Drug List is enabled, you can
display the Drug Label that was last
selected using the Options key.
To display the Drug label on the
Message Display for two seconds:
• press the * key.
For more information on Drug Labels,
see Chapter 3, Options.
Stop the infusion
To stop the infusion at any time:
• press the Hold key.
If an occlusion is detected
If an occlusion is detected, the Run
light remains lit, but the Pumping
indicator stops. The pump does not give
an occlusion alarm immediately, but
only alarms if the occlusion pressure
continues to exceed the occlusion
threshold for 10 seconds. This helps to
avoid nuisance occlusions.
However, the pump monitors any
temporary occlusions, and if such
occlusions persist, then the occlusion
alarm is generated.
If an occlusion is detected when the
occlusion alarm is set to Low, the pump
alarms immediately.
If an occlusion alarm occurs
If an occlusion alarm occurs,
immediately clamp the line to the
patient. Then inspect the fluid pathway
to determine what has caused the
obstruction.

Change the Occlusion alarm setting
You can check the current occlusion
alarm setting when an infusion is
running if you press the Occlusion
Alarm Setting key. You can change the
setting if you first put the infusion on
Hold, see steps in opposite column.
When you switch the pump on, the
Occlusion Alarm setting is always the
same, and is defined by the Technician
Menu configuration setting. You should
set the alarm to be appropriate for the
infusion before pressing Run.
The occlusion alarm setting determines
the amount of back pressure allowed
before the pump alarms. There are
three possible settings: Low, Medium
or High.
When an occlusion alarm occurs, the
pumping mechanism backs off to
reduce down-line pressure and bolus
potential (bolus potential is
approximately 0.3 mL regardless of
the rate and the administration set
used).
If there is no obvious reason for the
alarm, the message may occur because
you have not selected an appropriate
Occlusion Alarm Setting for the
infusion. If this is the case, you may
want to change the Occlusion Alarm
Setting.
To change the Occlusion Alarm Setting
during an infusion, whether or not an
alarm has occurred:
1. Press Hold to silence the alarm if
necessary, and stop the infusion.
2. Press the Occlusion Alarm
Setting key once to display the
current setting.
3. Press the Occlusion Alarm
Setting key repeatedly to display
the available settings.
4. When the correct setting is
displayed, press Run.
Note: A thick solution may be certain
cytotoxic agents, lipid-based fluids
and other viscous solutions, for
example Total Parenteral Nutrition.
Whilst the pump is infusing,
particularly at higher infusion rates, or
with thick solutions (see Note
opposite), or with small diameter
cannulas, you may see the following
alarm message:
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 alarm s, resulting in
patient injury or death.

Medium 5 psi, 259 mmHg, 34.5 kPa
High 10 psi, 517 mmHg, 68.9 kPa
WARNING: The Occlusion detection
system measures downline back pressure
in the administration 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.
Graseby Medical Ltd.
Operating the pump
Ending the Primary infusion
The pump warns you that the infusion
is complete when the Primary Volume
to be Infused reaches zero.
At this moment, the pump sounds a
two-tone alarm. You can decide to:
KVO infusion
If you press Silence to stop the alarm,
the pump continues to infuse at the
KVO (Keep Vein Open) rate. The KVO
rate is shown on the Rate display.
Depending on how the pump is
configured, the KVO rate may be:
• the default KVO rate of 3.0 mL/h,
• the programmed infusion rate if
that was less than 3.0 mL/h;
• the KVO rate specified for this
pump, see Specifying a different KVO
Rate, below.
The Message Display shows “KVO”, as
well as the combined Primary and KVO
volume infused, for example:
• silence the alarm and stop the
infusion - press the Hold key
• silence the alarm and continue to
infuse at the KVO Rate - press the
Silence key (see details below).
Specifying a different KVO rate
If the ‘KVO Rate Entry’ option has been
enabled in the Technician Menu, you can
use the Options key to specify a KVO
rate, before you start the infusion.
When you set the KVO rate you can go
to a maximum of 10 mL/h (on a 500
pump) or 3mL/h (on a 505 pump) or the
Max Primary Rate if one is also enabled
and set below these limits.
If the programmed infusion rate is less
than the set KVO rate, when the pump
goes into KVO, it will continue pumping
at the programmed lower rate.
For full details on how to set the KVO
rate, see Chapter 3, Options.
The pump continues to infuse at the
KVO rate. After six minutes, the two
tone alarm sounds again, as a reminder
that the KVO infusion is still running.
You can decide to:
• silence the alarm and stop the
infusion - press the Hold key
• silence the alarm and continue to
infuse at the KVO Rate - press the
Silence key.

About Secondary infusions
The pump has the facility for you to set
up and run a Secondary infusion, for
example, to:
• administer a dose of antibiotics to a
patient who is already receiving a
Primary infusion;
• administer a loading dose of a drug,
of a different concentration of the
same drug as in the Primary
container.
You use the Secondary/Bolus key to
program a Secondary infusion. The
Secondary volume infused is kept as a
separate total. It is not deducted from
the Primary Volume to be Infused.
Once you have started an infusion from
the Secondary set, the solution from the
Secondary container takes precedence
over the Primary infusion. For details
on what happens if the Volume to be
Infused is less than the contents of the
Secondary container, see page 2-27.
Secondary Rate and VTBI limits may
be set if enabled in the Technician
menu. See page 2-15 for more details.
Bolus feature enabled
If the Bolus feature has been enabled in
the Technician Menu, you can use the
Secondary/Bolus key to:
• run a Secondary infusion, where
the volume infused is not deducted
from the Primary Volume to be
Infused;
or alternatively,
• run a Bolus infusion, where the
volume infused is deducted from
the Primary Volume to be Infused.
Setting up a Secondary infusion
To set up a Secondary infusion, you
need a means of combining a Primary
and Secondary infusion. This may be
the combined Primary/Secondary (8C-
6200) IV Administration set from
Graseby Medical, product code 591.096.
Alternatively, use an administration set
with an injection site or Y-site (as
shown here) plus a Secondary
Administration set (not shown).
The basic steps for setting up a
Secondary infusion are described in the
following sections:
• lower the Primary solution container;
• prime the Secondary administration
set;
• connect the Secondary to the
Primary administration set;
• program the Secondary infusion
(with or without the Bolus feature
enabled);
• start the infusion.
2 — 26
Volumetric Infusion Pump Instruction Manual
Graseby Medical Ltd.
Operating the pump
Lower the Primary solution container
Open the packaging around the
Secondary administration set and find
the hanger that looks something like
this:
This should lower the Primary
container by approximately 20 cm
(eight inches). Make sure that the drip
chamber on the Primary container is
still at least 15 cm (six inches) above
the pump.
Take the Primary container from the IV
pole and use the hanger to suspend it
from the IV pole.
Prime the Secondary administration set
You must always follow the Instructions
for Use that accompany the particular
administration set to be primed. Each
set contains specific priming
instructions, and also gives details of
any warnings concerning the use of the
administration set.
WARNING: Do not run parallel infusion
lines below the pump. Delivering a
Secondary infusion means running a
second line
so may result in an inaccurate delivery of
medication, resulting in patient injury or
death.

following steps.
1. Insert the needle from the Secondary
set into the injection site on the
Primary set.
2. Keep the Secondary clamps closed
until you are ready to start the
Secondary infusion.
About the Secondary Volume to be Infused
Because the Secondary container hangs
on the IV pole at a higher level than the
Primary, the entire contents of the
Secondary container may be infused at
the end of the Secondary infusion. This
can happen even though the Secondary
Volume to be Infused is zero.
On a pump where Secondary Stop is not
enabled in the Technician Menu, you
must ensure that the amount that you
enter as the Secondary Volume to be
Infused is equal to the volume of fluid
in the Secondary container.
If the Secondary Stop feature is
enabled, the pump stops infusing and
sounds an alarm when the Secondary
infusion is complete and the Secondary
Volume to be Infused has been
delivered. You can then clamp the
Secondary set to prevent any more fluid
from being infused from the Secondary
container.
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.

appropriate to the rounded rate. For
example, if the volume entered is 14
mL and the time entered is 8 hours, the
actual rate calculated will be 1.75, and
then rounded to 1.8. The time then
automatically changes to 7 hours, 47

this against the Rate limit setting.
3. Check the value for the VTBI since
you may have accepted all values for
a previous Dose-Rate calculation
program and this will not have
updated the VTBI from the bag
volume.
4. If the VTBI or Rate limits are
acceptable, note all limits that are
set by using the Options key. Reenter Dose-Rate Calculation and
check if you have made a mistake in
programming the prescription.

Setting Rate and VTBI limits
Options
You can limit the infusion Rates and
VTBI (volume to be infused) values for
each pump. When you set up an
infusion, the pump rejects a Rate or
VTBI value that is not within the
Minimum/Maximum rate limits, or is
greater than the maximum VTBI.
For example, you should set a
maximum rate on a pump that is
intended for use in an Epidural
application, or set a maximum VTBI on
a pump to be used in a neonatal
environment. Setting rate limits is also
called Rate Capping.
Rate Taper, Volume Over Time and
Dose-Rate Calculation are also affected
by limit settings.
The following Options are used to limit
the infusion rates and volumes to be
infused on the pump:
For Primary infusions:
• Min Rate, Max Rate, Max VTBI.
For Secondary or Bolus infusions:
• Min S/B Rate, Max S/B Rate,
Max S/B VTBI.
To define the ranges, the items must be
enabled on the Technician Menu, and
then set using the Options key.
See page 3-32 for more details on how
limits affect programming an infusion.
The instructions on the following
pages explain how to set values for
the (Primary) Minimum and
Maximum Rate and Maximum
VTBI. Once you have understood
how to change these values, you
will find that you can set the
Secondary/Bolus minimum and
maximum rates in the same way.
Minimum and Maximum Infusion Rates
If the Primary ‘Min Rate’ and ‘Max
Rate’ are enabled in the Technician
Menu, their current settings are
displayed when you switch on the pump.
If the defaults have not been changed
(on a Model 500), the screen looks like
this:
The Secondary/Bolus Maximum and
Minimum rates are not displayed when
you switch on the pump, even if they are
enabled and set.

Entering rates
Rates must be entered as whole
numbers: they cannot include a decimal
point. If the Min Rate is set to zero,
there is no lower limit. The Max Rate
may be set to 999 (on a Model 500) or
99 (on a Micro 505).
Unless the display includes S/B,

Programming and running infusions with limits
If limits are set and you try to run an
infusion, the pump will prevent you
from running with a rate or VTBI value
entered outside the limits. This
includes special infusion modes such as
Volume over Time, Rate Taper and
Dose-Rate calculation. In the latter two
infusion modes, the pump behaves in a
slightly different way.
For Rate Taper, instructions on
programming with limits set are
described on page 3-16.
For Dose-Rate Calculation,
instructions on programming with
limits set are described on page 3-28.
If you change rates while running or put
the pump on hold and change the
volume, the limits are checked when
you press Run. The pump continues to
infuse at the previous rate when an
error is detected during a rate change
while running.
Rate limit settings also affect Quick
Rate changes.
When the pump detects a value which
is outside the set limits it sounds an
alarm and the Message Display shows:
Silence the alarm and enter a value
which is valid for the limits. The
previous value is restored to the LED
display.
If are using Quick Rate change, and try
to move outside the rate limits, the
pump will alarm with the limits
exceeded message, and the rate LED
will show the limit setting. If you are
changing the rate while the pump is
running, the infusion will continue at

KVO rate
Options
The pump automatically switches to a
KVO infusion when the programmed
infusion ends. The default rate for KVO
is 3.0 mL/h, or the programmed
infusion rate if that was less than 3.0
mL/h.
The KVO option, if enabled in the
Technician Menu, allows you to set a
different KVO rate.
The pump remembers the value entered
as described here, and uses it as the
KVO rate. You cannot set the KVO rate
to zero.
The range for the KVO rate must be
within the following limits:
500 0.1 to 10.0 mL/h
Micro 505 0.1 to 3.0 mL/h.
Setting a KVO rate
When you set the KVO rate, if the Max
Primary Rate is also enabled and set
below these limits, then that will define
the maximum KVO value you can enter.
If the programmed infusion rate is less
than the set KVO rate, when the pump
goes into KVO, it will continue pumping
at the programmed lower rate.
KVO rates cannot be changed when an
infusion is running, but if you press the
Options key, the current setting is
displayed.
1. Press the Options key until you see
the KVO rate display. The current
value flashes, showing that you can
enter a new value.
2. Enter the new KVO Rate using the
numeric keypad, then press * to
confirm.
If the rate is correct, press Options
to move on to the next Option.
In the unusual situation that the rate
you enter is not accepted, then the Max

The chapter contains two sections:
• warning messages with alarms,
divided into Continuous (backup)
alarm, Insistent alarms and Noninsistent alarms;
• warning messages with no alarms.
The chapter lists the possible causes
and recommended action to take for
each of the warning messages.
The chapter does not contain details of
the Volumetric pump System errors or
warnings that indicate a problem that
can only be solved by the Biomedical
engineering department, or by returning
to the distributor/factory. These are
described in the Volumetric Service
Manual.
Who should read this chapter
You should read this chapter to find out
how to solve any problems that arise
whilst you are using the Volumetric
pump.
You are likely to be in one of the
following groups:
• Biomedical engineering
department, needing to find out
what alarms may arise during the
normal operation of the pump
• People being trained, who have
access to the Instruction Manual as
additional training material
• People who have been trained, who
need a concise summary to remind
them of the Volumetric pump’s
alarms and a description of what to
do if the pump sounds an alarm.

Handling problems with the pump
Most problems in using the pump are
signalled by alarms whose
accompanying messages are described
in the rest of this manual.
You should also use your experience in
using the pump to take action if the
pump behaves as if it is faulty. Follow
the warnings and cautions on this page
to take appropriate action to send the
pump to a suitably qualified technician
for checking.
Pump will not switch on
If the pump does not switch on when
the On/Off key is pressed when
connected to an AC power supply.
Check that the keypad lockout feature
is not active, see Safety keypad lockout,
page 2-22.
CAUTION: Refer all service repair and
calibrations only to qualified technical
personnel. Unauthorised modifications to
the pump must not be carried out.
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.
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 Graseby Medical in order to have the
fault rectified.

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.
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.

Note: In Medium or High occlusion alarm settings, when downline pressure exceeds
the alarm threshold, the motor pauses, the Run key remains lit and the Pumping
indicator stops. If within 10 seconds the pressure drops back below the threshold,
pumping resumes and the alarm does not sound (if pressure remains high, the
alarm sounds). If repeated pressure spikes occur, causing the pump to enter this
filtering mode for a total of 30 seconds, measured over the last 4 minutes that the
pump was infusing, the alarm sounds. Occlusions detected in the Low occlusion
alarm setting cause an immediate alarm.
