How to set up your mattress
01. Place the Series5 mattress on the bed frame
with the airline connectors at the foot end
of the bed.The mattress has a black bottom
cover that should be placed directly on the
bed frame, the mattress cover will have airline
connectors on the bottom left corner, make
sure this matches with the airline connectors
on the mattress.The blue top cover should
face upwards, with the foot icon at the
bottom of the bed frame.
02. Check the bed frame is appropriate for use
with the mattress, i.e. the length and width of
the mattress are appropriate for the frame.
Place directly on a healthcare bedframe only,
never on top of another mattress.
03. Hang the control unit on the foot board at
the end of the bed using fold-out hangers
(Figure A). Connect airlines to control unit by
pressing quick connector into port on the side
of unit.“Triangle” symbol should face front.
(Figure B) Audible “click” indicates secure
connection.
Pressapclosed.
NOTE: The hanger lock strip (included, item #
P10064, Fig. C) can be used to help hold control
unit more snugly in place on thin foot boards such
as those often found on home health care beds.To
use, place the strip in position around the hanger
hooks as shown in Figure D.
Figure E Figure F Figure G
Figure A Figure B
Figure C Figure D
04. Connect the ends of the air lines with two right
angle male connectors (Figure E) to the ports
on the side of the mattress. Ports (Figure F) are
locatedbeneathafabricap(FigureG)near
the left corner at the foot end of the mattress.
Ensure that the airlines are not kinked or
twisted. Press connectors into ports until you
hear an audible “click” for each.
05. Ensure that theToggle switch is in the
“Alternating Pressure” position.
WARNING!
Toavoidpotentialforinjurytopatient’sfoot,
the control unit should be positioned such
thehangersremainushtotheheadboard
and do not extend on to the sleep surface.
This may require use of the hanger lock strip.
See note above.
CAUTION!
Do not cut air lines to increase separation. If
additional separation is needed to connect
air lines to the mattress, gently pull airlines
away from one another to lengthen the split
06. Ensure that green On/Off switch at side of
control unit is “Off ”. Plug power cord into wall
outlet. Press On/ Off switch “ON”.
07. When power switch is turned to ON, the
unit will power up in “Auto Firm” mode and
beginperformingasystemcheck.Thisllsthe
airsystemcompletely,inordertoconrm
the proper connection and function of both
the mattress and the control unit prior to
a patient being placed on the surface. If the
mattress is completely empty of air, this can
take as long as 20 minutes.You must leave the
mattressforafull20minutestofullyinate
before using or trying to change the comfort
level setting.
08. System will remain in “Auto Firm” mode
until this process is complete. “Low Pressure”
indicator light and audible alarm will remain
on as well.Audible Alarm can be disengaged
during this process by pressing the Audible
Alarm On/Off button.
09. When system check is complete, the control
unit will revert to previous comfort level
setting and “Alternate” mode. Low Pressure
indicator light will turn off. System is now
ready to be set for the next user.
NOTE: If “Low Pressure” remains on after 30
minutes, call for service.
Never thread airline through mechanical parts
of the bed or bed rails where normal bed
movement may damage the airlines, power
cord or the control unit itself. Check to be
sure the motion of the bed does not interfere
with the airlines, power cord or plug.
Always plug the power cable securely into
the wall outlet. Make sure the wall-mounted
outlet will accommodate a heavy duty or
hospital-grade plug and that the outlet is in
good working order.The plug of the power
cordshouldttightlyintothewalloutlet.The
plug body, the wall outlet, and the wall plate
should not be cracked or chipped.The plug
blades should be securely retained in the plug
body.The ground pin of the plug should be
intact and secure.
Do not connect the power cord to an
extension cord or to a multiple outlet strip.
If the use of extension cords or multiple
outlet strips cannot be avoided, use only
heavy duty or hospital-grade connectors
that are approved by the facility engineering
department. Multiple outlet strips should be
mountedonaxedobjecttoreducethe
risk of liquid spills and physical damage. In
addition, if multiple-receptacle outlet boxes
are used, they also should be protected from
the risk of liquid spills and physical damage.
All extension cords and multiple outlet strips
should be tagged and inspected routinely.
Do not cover the power cord with a rug or
carpet. Rugs or carpets can prevent normal
airow,whichcanleadtogreaterheat
built-up.Placethecordinalowornotrafc
area. Check to be sure the motion of the
bed does not interfere with the bed’s power
cord or plug.

General directions
Electromagnetic or other interference
See Appendix A p23.
This equipment generates, uses and can radiate
radio frequency energy and, if not installed and
used in accordance with the instructions, may
cause harmful interference to other devices in the
vicinity.
However, there is no guarantee that interference
will not occur in a particular installation. If this
equipment does cause harmful interference to
other devices, which can be determined by turning
the equipment off and on, the user is encouraged
to try to correct the interference by one or more
of the following measures:
- Reorient or relocate the receiving device.
- Increase the separation between the equipment.
- Connect the equipment into an outlet on a
circuit different from that to which the other
device(s) are connected.
- Consult the manufacturer for help.
Power loss / patient transport
To seal air into mattress, simply disconnect the
quick connector from the control unit, and place
“transport”
Head-of-bed elevation
All support surfaces using air as a support medium
are designed for distributing pressures over the
bodyinaat,horizontalposition.Bendingthe
support surface and the body at the midpoint
when elevating the HOB concentrates the body

Series5 Mattress User Guide 13
weight over the centre of the surface, stressing
that small area.
This extreme change in dynamics creates a
challenge for all air support surfaces. Maximum
pressuremanagementbenetsarerealised
between zero and 30° HOB elevation. Beyond
30°, the amplitude of the changes in the air
cylinders begins to decrease in proportion to the
increased elevation of the HOB. Although the
mattress will maintain its support and therapeutic
capabilities up to and including 70° HOB, for
maximumbenetwerecommendthatany
pressure management surface be used with the
head of the bed elevated as little as possible, and
for limited periods at a time.
WARNING!
DO NOT MOVE USER ON MATTRESS
ONLY.
Mattress should not be used alone for user/
patient transport.
WARNING!
Lateral rotation mode should not be
used with head of bed elevated beyond
30°. Instead, select alternating pressure or
poweredotation(oat)mode.WithHOB
elevated, the alternating pressure mode can
facilitate maximum pressure management
effectiveness while minimising the possibility
of patient falls.
Troubleshooting patient complaints
Occasionally a patient will complain of feeling as if
they are “sinking into a hole”.
01. Sometimes this happens when the head of
the bed is elevated and the mattress is in
either lateral rotation or alternating pressure.
This sensation is a combination of the
deationofthecylindersduringtheircycle
and the increased weight of the patient on
the sacrum and pelvis when the head of the
bed is elevated.This demonstrates the need
to minimise elevation of the head of the bed.
To improve this situation decrease elevation of
the head of the bed.
02. Often patients complain when they are supine
or side-lying and are not used to the changing
pressures within the air system. Reassure the
resident that this is normal functioning, as the
cylindersalternatelyinateanddeate.The
“deated”tubesarenotfullydeated.Some
air is always maintained in them to prevent
bottoming out. After reassurance, patients get
used to the changing pressures
Bed linens
Useatsheets,knittedstretch-tsheets,ordeep-
pocketttedsheets.Useasfewlayersoflinens
or underpads beneath the patient as possible to
allow best possible envelopment, immersion and
pressure management performance.
Bed rails
Due to concerns over the possibility of patient
entrapment, OSKA recognises that the use of rails
of any length is a matter currently addressed by
laws/guidelines, and by individual facility protocol.
It is the responsibility of the facility to be in
compliance with these laws, which typically require
that decisions on the use of bed rails of any type
are based on assessment of the physical and
mental status of each patient individually. If bed-rails
are needed by the patient to prevent fall-related
injury,asdeterminedbythisfacilityassessment,we
recommend that the bed-rails be locked in the up
position at all times.We do not require use of bed-
rails unless the patient is deemed to be safer with
them than without them.
CPR
TodeatethemattressforCPR,simplydetachthe
mattress from the pump by unplugging the airlines
from the pump (see Figure B).
Storage and transportation
Store the mattresses in a clean, dry place. Once
the mattress is removed from the box, store in a
atpositionifpossible.Ifmattressmustbestored
onitsside,ensurethattheinationsystemisin
correct position within the mattress prior to placing
a user on the surface. Protect from damage. Avoid
temperature extremes (below freezing or above
48°C). Allow to acclimate to room temperature
before use. Do not stack more than 10 high.
Do not stack other equipment on top of the
mattresses.
Store the control unit in a clean, dry place,
protected from accidental damage or falls.
Avoid temperature extremes (below freezing or
above 48°C). Do not stack other equipment on
top of the control unit.
Avoid storage of other equipment on top of
the mattress.When removing the mattress from
storage,alwaysensuretheinternalinationsystem
is aligned correctly prior to placing a patient on
the surface.
CAUTION!
Be careful not to puncture the mattress with
needles or sharp instruments.This may result
in loss of integrity of the cover or internal air
system. Regularly inspect the mattress cover
for cuts, rips, cracks or tears. Do not use the
mattress if the cover is damaged.
For transportation, secure to prevent damage
or falls. For shipment, use box and packaging as
provided by the manufacturer.

Use in wound care
Use of Series5 mattress is only one element of
care in the prevention and treatment of pressure
ulcers. Frequent repositioning, proper care, routine
skin assessment, wound treatment and proper
nutrition are but a few of the elements required
in the prevention and treatment of pressure
ulcers. As there are many factors that may
inuencethedevelopmentofapressureulcerfor
each individual, the ultimate responsibility in the
prevention and treatment of pressure ulcers is with
the health care professional.

Series5 Mattress User Guide 15
Evacuation base
The Series5 comes with evacuation straps within
it‘s base.
It is very important that the safety equipment, as
well as the evacuation procedures, are well planned
and known in advance.
Thesecoverscansignicantlyhelpyoubeprepared
inthecaseofareorotheremergencywhenaless
mobile patient will need to be evacuated.
Handles appear on all 4 sides of the cover and the
velcroreevacuationstrapsarehousedsecurely
in pockets on the 2 longer sides with their ends
sticking out for easy access.These straps are used in
the case of an emergency to secure the patient to
the mattress before transporting them to safe area.
Evacuation instructions
• Let the patient know what is about to happen.
• Lower and lock the bed in position.
• Pull the velcro evacuation straps out of the base
and fasten.
• Using the outer handles at the foot end of the
mattress, turn it outwards from the bed.
• Carefully drag the mattress and patient down
ontotheoor.
• Use the outer handles at the foot end of the
mattress.The working position should be a little
bit leaning back.
Down the stairs
• Walking backwards, continue
until the main part of the
mattress slides pass the top
stair.
• Turn your back towards the patient and look in
the direction you are moving.
• Holding one hand on the stair rail and the other
hand on the middle handle of the mattress,
begin to pull.
• Walk down the stairs maintaining speed, without
running, is important.
Training/practise
To bear in mind when training.
Pulling down from the bed:
• Make sure the patient in the bed is not at the
very top of the mattress. If they are, it increases
the risk of hitting their head on the bed when
pulling down.
Pulling on the stairs:
• Practice this technique
by pulling an empty
mattress down the stairs.
• When training with a person on the mattress,
fasten a string or rope onto the handles at the
head end.This enables another person to then
walk behind the mattress and help out.
• Practicing on the stairs where an evacuation
may be necessary is advisable.
General:
• The purpose of the training is not to carry
it out at high speed, but to grasp the correct
technique.
Training covers:
• When the equipment is used to evacuate, heavy
strain is put on the seams and handles. Always
WARNING!
It is imperative that anyone performing an
evacuation must have acquired the necessary
training. Before commencing any evacuation
always check the equipment, cover and
mattress to ensure the evacuation can be
carried out safely.
Ensuring the mattress is safe to use for
evacuation is the user’s responsibility.
check the seams and handles at the end of
training. It is advisable to mark any equipment
used for training as “Training equipment” and
use it only for this purpose
Explanations
• Always use the velcro straps when evacuating
a patient to prevent the patient sliding/rolling
down from the mattress.
• Pulling at the foot end reduces the strain on the
puller, which means faster and safer evacuation
is possible.
• Pulling the mattress on the stairs is the hardest
part of the evacuation and should therefore be
practised carefully.
Keep the patients arms inside the velcro straps.This
prevents the user grabbing hold of something out
of fear.
Cleaning
V-Guard cleaning and aftercare guidelines
OSKA V-Guard technology covers are durable
but, as medical devices, they need treating with
great care.The surface is vapour permeable so it is
waterproof, but breathable to reduce sweating of
patient.This outer barrier must not be penetrated.
Even the smallest breach of this barrier will cause
uidtopenetratethemattress.
Therearespeciccleaningandcareinstructions
that need to be strictly adhered to prolong the life
of the product.
1. General directives
1.1 Abrasive cleaning agents should
NOT be used.
1.2 In addition, due to the range of cleaning
chemicals and conditioners being used,
customers should ascertain that any fabric
performs as expected, without any adverse
effect.
1.3 Some surface wrinkling may result from
cleaning procedures.This should have no
adverse effect on the fabric’s properties.
1.4 If customers have their own particular cleaning
methods that must be used and that are not
covered in this article, they should consult
OSKA for further direction and guidance.
2. Washing and disinfection
2.1 All polyurethane coatings need to be treated
with care when cleaning the surface. Many
industrial cleaning agents are extremely harsh
on the coating and can cause it to break down.
2.2 Forsupercialdirtuseadisposablewipeanda
warm solution of neutral detergent. Do not use
abrasive cleaners.
2.3 Disinfect in situ using 0.1% sodium hypochlorite
solution (1000ppm available chlorine).Wipe off
any residue with clean water.V-Guard covers
can tolerate 10,000ppm chlorine but using a
weaker solution of 1,000 ppm will reduce the
risk of a high concentrate being left on the
surface.
2.4 The fabrics are able to be washed in warm
soap water at up to 95°C.
2.5 All cleaning agents and disinfectants must be
thoroughly rinsed off and the item dried before
storage.
3. Drying
3.1 Spin and tumble dry on a low setting (not
more than 130°c.The fabric surface may
wrinkle but this will not impede function).The
operator ensures it is removed as soon as all

Air lter preventive maintenance
TheairlterfortheControlUnitshouldbe
checked routinely for signs of dirt or contamination.
The frequency for cleaning depends on the air
quality.Theairlterisaccessiblefromthebackside
oftheControlUnit.Asthelteriswhite,theneed
to clean is obvious. Simply turn the controller off
andremovetheplasticcover,removethelter,and
hand wash using warm water and mild detergent.
Rinse thoroughly and allow to air dry. Replace the
lterandtheplasticcover.
Delamination
Delamination is when the layers within the structure
of the mattress cover separate.This can be
caused by using incorrect chemicals or too high a
concentrate of cleaning chemicals on the surface.
How to prevent delamination
OSKA V-Guard Technology covers incorporate a
special layering system to make them much more
resistant to delamination than many other mattress
covers. However, to help prevent delamination:
01. Always abide by the cleaning instructions
02. Avoid using chemicals with too high
concentration.
03. Ensure cleaning chemicals are always
thoroughly rinsed off before allowing to dry
04. TheV-Guard covers can tolerate up to
10,000ppm chlorine but using a weaker
solution of 1,000ppm will reduce the risk of a
high concentrate being left on the surface
05. Ensure the covers are thoroughly dry before
using or storing the mattress
Strikethrough
Strikethroughoccurswhenthebresinthe
mattress covers start to break down. Small cracks
develop, which on inspection, may not be visible.
Thismeansuidsandothercontaminatescanpass
4.2 Avoid excessive pressure and always
thoroughly dry fabric before re-use or storage.
Do not fold away wet or store in damp
conditions.
4.3 Keepawayfromsharpobjects.
5. Damages and replacement
5.1 Regularly check the inside of the cover for any
signs of leakage
5.2 If the cover leaks then the waterproof barrier
has been broken and a new cover should be
purchased from OSKA
General guidelines
Do not puncture the mattress with needles
or sharp instruments.This may result in loss of
integrity of the mattress air system and will void
the warranty. Inspect the covers and zipper area
for signs of damage, puncture, or wear that could
resultinuidpass-through.Ifthecoverisstained,
soiled, or torn, inspect the internal components for
signs of contamination. If contamination is evident,
quarantine the mattress and remove from service
following infection control procedures.
The air control unit should be dusted every 30 days
and cleaned with a damp cloth and mild detergent.
Disconnect air lines from control unit and
use “transport” cap to seal air into mattress
(see PATIENT TRANSPORT page 11).Turn
unit off and unplug from wall before cleaning.
Wipe down with using damp sponge or
cloth that has been thoroughly wrung out to
remove excess liquid. Do not allow liquids to
penetrate the user panel.
through the cover and contaminate the core of the
mattress.
How to prevent strikethrough
Covers are most susceptible to strikethrough
damage when they are wet. During cleaning,
extra care should be taken to avoid abrasion of
the surface. OSKA V-Guard Technology covers
incorporate a special layering system to make them
much more durable than many other mattress
covers. However, to help prevent strikethrough:
01. Always abide by the cleaning instructions
02. Avoid using chemicals with too high
concentration.
03. Ensure cleaning chemicals are always
thoroughly rinsed off before allowing to dry
04. TheV-Guard covers can tolerate up to
10,000ppm chlorine but using a weaker
solution of 1,000ppm will reduce the risk of a
high concentrate being left on the surface
05. Ensure the covers are thoroughly dry before
using or storing the mattress
Routine inspection of power cord and safety tips
to prevent res
01. Assure that the electrical resistance of the
safety ground conductor and the level of
leakage current (line conductor-to-safety
ground and neutral conductor-to-safety
ground) meet applicable standards for
resistivity and leakage current. Protection
afforded by the ground pin is negated if the
receptacle is not properly grounded. If you
have questions about the adequacy of your
facility’sbuildingwiring,contactaqualied
electrician or consult the code authority in
your area.
02. Check all electrical outlets, including accessory
outlets for cleanliness, physical integrity and
functionality.The IEEE standard 602-1996,
section 4.2.2 advises that hospital-grade
outlets be used and that they should be
mounted with the ground pin or neutral blade
up to assure that any metal that may drop
between the plug and the wall will most likely
contact an unenergized blade.
03. Check the power cord to assure that contact
pins are straight and secure.
04. Routinely inspect the power cord for damage
sustained from crushing, pinching, shearing,
cutting, or from being worn through.They can
be damaged by bed movement, deterioration
from use or aging, or human or equipment
trafc.Thecord’sinsulationshouldbeintact
and there should be no evidence of bulging,
stretching, crimping, cracking, or discolouration,
especially at the ends, where the cord is
attached to the plug body and the control unit
05. Regularly inspect as parts of the bed frame,
motor,mattressandcontroller,andtheoor
beneath and near the bed for build-up of dust
and lint.
06. Inspect the cover of the control panel to
assure that the covering is not cracked or
damaged, allowing liquids or other conductive
material to penetrate to the switches.
07. Report any unusual sounds, burning
odours, or anything unusual to maintenance
personnel. Discontinue use of the power
cord immediately and contact OSKA for
replacement.
