Safety Warnings
• It is the responsibility of the care giver to ensure that the user can use this product
safely.
• Whilst the patient is unattended, safety sides should be used based on clinical
assessment and in line with local policy.
• Alignment of the bed frame, safety sides and the mattress should leave no gap
wide enough to entrap a patient's head or body, or to allow egress to occur in a
hazardous manner where entanglement with the mains power cable and tubeset or
air hoses may result. Care should be exercised to prevent occurrence of gaps by
compression or movement of the mattress. Death or serious injury may occur.
• Make sure that the mains power cable and tubeset or air hoses are positioned to
avoid causing a trip or other hazard, and are clear of moving bed mechanisms or
other possible entrapment areas. Where cable management flaps are provided
along the sides of the mattress, these should be used to cover the mains power
cable.
• Electrical equipment may be hazardous if misused. There are no user-serviceable
parts inside the pump. The pump's case must only be removed by authorised
technical personnel. No modification of this equipment is allowed.
• The mains power socket/plug must be accessible at all times. To disconnect the
pump completely from the electricity supply, remove the plug from the mains
power socket.

1. Introduction
About this Manual
This manual is your introduction to the Nimbus® 3 and
Nimbus 3 Professional systems. Use it to initially set up
the system, and keep it as a reference for day-to-day
routines and as a guide to maintenance.
About Nimbus 3 and Nimbus 3 Professional
Nimbus 3 and Nimbus 3 Professional are Dynamic
Flotation Systems for the prevention, treatment and
management of pressure ulcers.
Nimbus 3 and Nimbus 3 Professional systems comprise
a pump and mattress replacement which can be used on
standard hospital and normal domestic beds. Beds can
be adjusted or profiled with the mattress in position.
The Nimbus 3 Professional mattress has the following
additional features to enable the patient to be proned,
and to assist with pressure area and patient care
management:
• A Head Section Deflate Control to allow the three
head cells to be fully deflated.
• Individual Vent Valves to allow 16 of the 20 cells to
be independently deflated.
The Nimbus 3 and Nimbus 3 Professional mattresses
incorporate an advanced AutoMatt® sensor pad which
makes sure that the patient is automatically supported at
optimum pressures regardless of size, height, position or
weight distribution.
If cardiac arrest occurs, the Nimbus 3 and Nimbus 3
Professional mattresses can be deflated in less than 10
seconds to allow cardiac resuscitation procedures to be
performed.

Nimbus 3 Pump
The same pump is used on the Nimbus 3 and Nimbus 3
Professional systems.
The pump comprises a moulded case with non-slip feet
on the base and rear, and an integral carry handle.

Front Panel
The pump has two modes of operation:
• Dynamic mode that cycles the support surface
beneath the patient every 10 minutes providing
periods of pressure relief for the whole body.
• Static mode where the support surface remains
constant (all cells equally inflated).
The controls and indicators are located on the front
panel, and a sophisticated alarm system differentiates
between normal operation and genuine system faults. If
an alarm situation is detected a flashing indicator will
illuminate, together with an indication of the cause of
alarm, and an audible warning will sound.
The pump can be fixed to the foot end of a hospital bed
by the separate bed bracket. The bed bracket fits in the
pump handle and then clips onto most common bed
frames. The pump can also be stood on the floor, either
upright or on its rear cover.

The standard protective cover comprises a 2-way stretch
cover zipped to a durable anti-slip base. The zips are
protected by flaps to prevent ingress of contaminants,
and allow easy removal of the cover for cleaning.
Alternative covers with advanced properties, such as
Advantex® and eVENT®, are also available (Refer to
“Cover Specification” on page 30).
Cells
The Nimbus 3 mattress comprises 20 polyurethane (PU)
cells providing support to the user in either Alternating
or Static modes. The cells are grouped in four sections,
each of which has a specific function:
• The three Head cells remain at a constant pressure
for pillow stability and patient comfort.
• The eight Torso cells combine alternating and static
pressure characteristics to support patients fully in
both lying and sitting positions without the risk of
‘bottoming’.
• The four Thigh cells cycle dynamically to maximise
pressure relief.
• The five Heelguard® cells are specially powered to
maximise the pressure relief under the heels.

Page 10
AutoMatt
The advanced AutoMatt sensor pad is under the cells,
and makes sure that the patient is automatically
supported at optimum pressures regardless of size,
height, position or weight distribution.
CPR Control
The CPR (Cardio-Pulmonary Resuscitation) Control is
at the foot end of the mattress, and allows the air to be
evacuated in under 10 seconds.
Transport Control
The Transport Control is next to the CPR Control. When
operated, it seals the mattress so that air is not exhausted
when the tubeset is disconnected and also creates an
even pressure in all the cells.
Tubeset
The tubeset incorporates a flexible, compact anti-kink
tube that is resistant to crushing and any subsequent
obstruction of air flow. Each end has a quick-lock
system for easily connecting and disconnecting the air
supply at the pump and mattress.
Nimbus 3 Professional Mattress
The Nimbus 3 Professional mattress is of similar
construction to the Nimbus 3 mattress, with the addition
of a Head Section Deflate Control, individual Vent
Valves on 16 of the 20 cells and a Shoulder Support
Cell.

Head Section Deflate Control
Page 11
Head Section Deflate
Control
This is a two-position rotary-action control at the head
end of the mattress:
• Dynamic (Normal) Mode. The three cells in the Head
Section are inflated at a constant pressure and the
remaining 17 cells alternate.
• TriCell Head Section Deflate. The three cells in the
Head Section are fully deflated to assist with patient
care management, and the Shoulder Support Cell (the
fourth cell, next to the Head Section) is inflated to a
constant pressure to support the patient’s shoulders.
The remaining 16 cells alternate.
Cells
The Nimbus 3 Professional mattress has the same
number of cells as the Nimbus 3 mattress (20 cells). The
function of the first four cells at the head end of the
mattress is different on the Nimbus 3 Professional:
• The three cells in the Head Section are either fully
inflated or fully deflated, depending on the position
of the Head Deflate Control, to assist with patient
care management. The cells are specially powered to
enable them to be fully deflated.
• The single Shoulder Support Cell (the fourth cell,
next to the Head Section) has a shallow cutout in the
mid-section of the cell. This is to allow access to the
neck area for clinical procedures and to ensure the
smooth, uniform extension of the neck during
deflation. Its operation is controlled by the Head
Section Deflate Control: the cell is either fully
inflated to support the patient’s shoulders or
alternates (together with the remaining 16 cells).
• The remaining 16 cells (seven Torso cells, four Thigh
cells and five Heelguard cells) have the same basic
function as on the Nimbus 3 mattress.
Vent Valves
The seven Torso cells, four Thigh cells and five
Heelguard cells have individual Vent Valves to allow
each cell to be independently deflated, to assist with
pressure area and patient care management.

2. Clinical Applications
Indications
The Nimbus 3 and Nimbus 3 Professional systems are
indicated for the prevention and management of all
categories1 of pressure ulcer when combined with an
individualised monitoring, repositioning and wound care
programme.
The Nimbus 3 and Nimbus 3 Professional mattress is
designed for patients weighing up to 250 kg (550 lb).
The Nimbus 3 and Nimbus 3 Professional cushion is
designed for patients weighing up to 250 kg (550 lb).
Contraindications
Cautions
Do not use Nimbus 3 and Nimbus 3 Professional systems
for patients with unstable spinal fractures.
If patients have other unstable fractures, or conditions
which may be complicated by a soft or moving surface,
advice should be sought from an appropriate clinician
before use.
While the Nimbus 3 and Nimbus 3 Professional systems
have been designed to manage patients up to the weight
limits indicated above, those approaching this upper limit
are likely to have additional care and mobility needs and
may be better suited to a specialist bariatric system.
Active therapy (alternating) cushions may be unsuitable
for patients with poor sitting posture or pelvic deformity;
advice from a seating specialist should be sought.
Care of the patient
when sitting
Seated patients are at increased risk of pressure ulcers
particularly if they are immobile or have wounds over the
seating area. For optimal outcome, provide a pressure
redistributing seat cushion in a chair which promotes a
good sitting posture and has a level base seat to support the
cushion, in addition to an individualised repositioning
programme.
The above are guidelines only and should not replace clinical judgement.
The Nimbus 3 and Nimbus 3 Professional systems represent one aspect of a
pressure ulcer management strategy; if existing wounds do not improve or the
patients condition changes the overall therapy regimen should be reviewed by
the prescribing clinician.
Mattress and cushion combinations may have different upper weight limits.
Cushions should be used in combination with pressure-redistributing
mattresses to provide 24-hour therapy.

3. Installation
The Nimbus 3 and Nimbus 3 Professional systems are very simple to install
using the following guidelines.
Refer to Section 4, Page 11 “Controls, Alarms and Indicators” for a
comprehensive description of the controls and indicators on the pump and
mattress.
Preparing the Nimbus 3 and Nimbus 3 Professional Systems for Use
1. Remove the system from the packaging. You
should have the following items:
• Nimbus 3 pump, with integral mains power cord.
• Nimbus 3 mattress replacement or the
Nimbus 3 Professional mattress replacement.
• Bed bracket.
• Tubeset.
Installing the Nimbus 3 or Nimbus 3 Professional Mattress
1. Remove the conventional mattress from the bed
frame and check that there are no protruding bed
springs or sharp objects on the bed frame surface.
Heavily ridged bed baseboards may require special considerations for
correct system operation - consult your ArjoHuntleigh representative.
2. Unroll the mattress onto the bed base and make
sure that the CPR is at the foot end, and the CPR
label is hanging freely.
3. Attach the mattress to the bed frame using the hook
and loop securing straps.
If the bed can be profiled to any position (i.e. raised or lowered), attach the
mattress to the movable parts of the bed only.

seconds of normal pressure being detected the indicator
is switched off and the air supply restarted.
The LOW PRESSURE indicator is illuminated whenever
the pump detects low pressure within the mattress.
This may indicate that there is insufficient pressure to
support a patient or that the Transport control is turned
to the TRANSPORT position whilst the pump is on and
connected to the mattress.
The LOW PRESSURE indicator will be switched off
once normal pressure is reached.
Alarm
The pump unit incorporates a sophisticated alarm
detection system that differentiates between patient
movement and genuine alarm conditions.
Whenever an alarm condition is detected the red Alarm
triangle starts flashing together with an indicator of the
cause of the alarm. Additionally, an audible warning
will sound, which can be cancelled by pressing the
Alarm MUTE button (Refer to “Alarm MUTE” on
page 11).
The triangular Alarm symbol is displayed with one or
more of the following indicators:
12
Page 19
• LOW PRESSURE (Refer to “LOW PRESSURE” on
page 12).
• HIGH PRESSURE (Refer to “HIGH PRESSURE” on
page 12).
• PUMP FAULT (Refer to “PUMP FAULT” on
page 13).
• POWER (Refer to “POWER Fail” on page 13).
For all alarm conditions except Power Fail, once the alarm condition has
been detected and displayed, it can only be cancelled by switching the pump
unit off and then back on.
Refer to Section 8, Page 27 “Troubleshooting” for
possible causes of the above alarm conditions.
PUMP FAULT
The PUMP FAULT indicator is illuminated when an
internal pump malfunction is detected.
The fault can only be rectified by carrying out a service
on the pump.
POWER Fail
The POWER indicator will flash when a mains power
failure has been detected.
The alarm will continue until the mains power is
resumed or the pump is switched off using the POWER
switch on the pump control panel.
Service Indicator
The
symbol will be illuminated after a set number of
running hours to indicate that the pump is ready for a
service.
This service period is set to 12 months.
The pump will continue to operate normally even when the
illuminated.

CPR Control
Transport Control
Transport Control
This sets the mattress into TRANSPORT mode where the
support surface is equally pressurised and the pump and
tubeset can be removed. In this mode the mattress will
support the patient for up to 12 hours.
CPR Control
The CPR (Cardio-Pulmonary Resuscitation) Control
provides a means of rapidly deflating the mattress to
allow normal resuscitation procedures to be carried out.
The CPR control is used to deflate the mattress for packing and storage.
Additional Controls on the Nimbus 3 Professional Mattress
The following two controls are on the opposite side of
the mattress to the CPR/Transport Control:
Head Section Deflate
Control
This is a two-position rotary-action control at the head
end of the mattress:
• Dynamic (Normal) Mode. The three cells in the Head
Section are inflated at a constant pressure and the
remaining 17 cells alternate.
• TriCell Head Section Deflate. The three cells in the
Head Section are fully deflated to assist with patient
care management, and the Shoulder Support Cell
(next to the Head Section) is inflated to a constant
14

pressure to support the patient’s shoulders. The
remaining 16 cells alternate.
TriCell Head Section Deflate
Dynamic (Normal) Mode
16 Vent Valves
The seven Torso cells, four Thigh cells and five
Heelguard cells have individual Vent Valves to allow
each cell to be independently deflated, to assist with
pressure area and patient care management.

5. Operation
These instructions cover day-to-day operation of the system. Other operations, such
as maintenance and repair, should only be carried out by suitably qualified
personnel.
Refer to Section 4, Page 11 “Controls, Alarms and Indicators” for a
comprehensive description of the controls and indicators on the pump and
mattress.
Installing the System
Before using the Nimbus 3 or Nimbus 3 Professional
system make sure:
1. The system has been installed correctly in
accordance with Section 3, Page 7 “Installation”.
2. The CPR unit on the mattress is closed and locked
in position.
3. The Transport control on the mattress is set to
NORMAL.
4. If a Nimbus 3 Professional system is being
installed, make sure that on the mattress:
• All 16 Vent Valves are closed.
• The Head Section Deflate Control is set to
Dynamic (Normal) Mode.
Inflating the Mattress
1. Switch the pump POWER switch to ON.
The ON / RESET ALARM indicator below the
POWER switch should illuminate.
2. The pump will now run a self test for
approximately 3 seconds when all the indicators on
the front panel will be illuminated.
3. If the pump detects low pressure (e.g. a deflated
mattress) it will enter an inflation sequence with the
LOW PRESSURE and WAIT indicators illuminated.
4. Once normal operating pressure has been reached
both the LOW PRESSURE and WAIT lights will
extinguish.
It may take up to 15 minutes to inflate the mattress.
The three Head Section cells and the five Heelguard cells will inflate more
slowly than the rest of the mattress.
Testing the Power
Fail Alarm
The Power Fail Alarm is powered by a rechargeable
battery. The duration of the alarm will depend on the
level of charge in the battery.
16
Page 23
The battery may have become discharged or reached the
end of its life. It is therefore recommended that the alarm
is tested before the pump is used, as follows.
1. Connect the pump to the mains power supply,
switch ON and allow it to run for 10-15 seconds.
2. Remove the mains power at the wall socket without
switching the pump off.
3. The power fail alarm should operate within 10
seconds, as follows:
• The red Alarm triangle will flash.
• The POWER indicator will flash.
• An audible warning will sound.
4. The alarm will continue until the mains power is
resumed or the pump is switched off using the
POWER switch on the pump control panel.
5. If the alarm does not operate, run the pump for
approximately four hours to recharge the battery.
6. Retest the alarm after the battery has been
recharged. Allow the alarm to operate for
approximately two minutes to ensure that it has
been adequately recharged.
7. If the alarm does not operate for two minutes, call
the service engineer.
If the Power Fail Alarm does not operate after this test and a service
engineer has been called, the pump can continue to be used with regular
checks of the Power-On status.
All other alarms will continue to function as normal.
Deflating the
Mattress
To deflate and store the mattress, do the following:
1. Switch off the pump, and disconnect the pump from
the mains power supply.
2. Remove the tubeset from the pump and mattress
(Refer to “Disconnecting the Tubeset” on page 10).
3. Activate the CPR control.
4. Make sure the Transport control is set to NORMAL.
5. Roll up the mattress, starting at the foot end.
Make sure the mattress is dry before rolling it up.

System Optimisation
The Nimbus 3 and Nimbus 3 Professional systems
automatically compensate for patient weight
distribution and position, to optimise the pressure
relieving performance.
To make sure that the pressure relieving properties are not impaired, the
mattress cover must not be pulled tight and covering sheets should fit loosely
using the attached clips.
The system provides two modes of operation:
• Dynamic mode provides the optimum pressure
relieving performance and should be used in most
cases. In Dynamic mode the support surface beneath
the patient is cycled every 10 minutes.
• Static mode provides a stable, non-moving support
surface for instances where a dynamic support
surface is contra-indicated. In Static mode the
support surface remains constant (all cells are
equally inflated).
Nimbus 3 Professional
Mattress only
On the Nimbus 3 Professional system, the following
therapeutic positioning controls along the side of the
mattress offer further operating modes in combination
with the Dynamic pressure relief option, to assist with
pressure area and patient care management:
1. Head Section Deflate Control. This controls the
three cells in the Head Section:
• Dynamic (Normal) Mode, where the three Head
cells are inflated at a constant pressure and the
remaining 17 cells alternate.
• TriCell Head Section Deflate, where the three Head
cells are fully deflated, and the Shoulder Support
Cell is inflated to a constant pressure to support
the patient’s shoulders. The remaining 16 cells
alternate.
2. 16 Vent Valves.
The seven Torso cells, four Thigh cells and five
Heelguard cells have individual Vent Valves to
allow each cell to be independently deflated.
Selecting the
Operating Mode
• The pump defaults to the Dynamic operating mode
when switched on.
• Both Static and Dynamic modes of operation are
selected by the STATIC button on the front panel.
• When Static mode is selected the indicator on the
STATIC button illuminates.
18
Page 25
To change the operating mode:
1. To select Static mode from Dynamic mode press the
STATIC button once. An audible tone will sound
and the indicator on the button will illuminate to
show that the system is in Static mode.
2. To select Dynamic mode from Static mode press the
STATIC button once. An audible tone will sound
and the indicator on the button will extinguish.
Silencing Audible
Alarms
In its normal operating mode an audible alarm can only be silenced after an
alarm has occurred. An internal setting can be used to change the mode of
operation so that this button can pre-silence an alarm. Call your service
engineer if this option is required.
Comfort Control
The mattress cell pressure can be manually adjusted for
patient comfort using the rotary COMFORT CONTROL.
To change the comfort setting:
• Turn COMFORT CONTROL clockwise for a firmer
setting and counterclockwise for a softer setting.
• The mattress minimum pressure is maintained at the
chosen level.
The system automatically compensates for patient size, height, position and
weight distribution to provide optimum support regardless of the COMFORT
CONTROL setting.
Transport Control
Audible alarms can be silenced using the MUTE button.
To silence an alarm push the MUTE button once (the
indicator on the MUTE button will remain illuminated).
This seals the mattress and allows the removal of the
pump for patient transport. The patient will remain
supported by the mattress for up to 12 hours in Transport
mode. To set the Transport mode:
1. At the foot end of the mattress turn the Transport
control knob clockwise to TRANSPORT.
2. Turn the pump off and disconnect the tubeset.
If the Transport control is set to TRANSPORT with the tubeset connected and
the pump switched on, then the pump will indicate a Low Pressure fault
alarm.
To resume normal operation:
1. Re-connect the pump and tubeset to the mattress.
2. Turn the Transport control knob counterclockwise
to NORMAL.
