2. Alternating Pressure Operation Principle
Patients who spend a lot of time in bed will often experience vascular compression on any part of their body where
there is a bony protrusion, such as the shoulders and sacrum. This can easily cause decubitus pressure ulcers to form,
leading to further complications such as infection.
The interleaved pressure relief areas on our alternating pressure support surfaces provide periodic relief from
vascular compression to the whole body by dynamically redistributing your patient’s weight, preventing and alleviating
decubitus pressure ulcers. For your patient’s comfort, the three-cell pillow zone at the head of themattress is designed
to provide static support for your patient’s head.
3. Guidelines
Always use pressure care systems under the advice of a suitably qualified medical professional. The patient’s pressure
ulcer risk assessment scores, weight and the handling considerations for caregivers should be considered to ensure
that the appropriate system is selected.

10. CPR Valve Operation (Mattresses only)
The CPR valve allows the mattress to deflate quickly when CPR is to be performed on the patient. The CPR valve is
located at the head end of the mattress. The system will operate normally when the CPR pull tag (Fig. 3) is securely
located in the CPR air outlet and will deflate when the CPR pull tag is pulled from the CPR air outlet.
Fig: 3
11. Installation
11.1 Mattresses
12.Unroll the mattress on the bed with the connector hoses at the foot end.
13.Secure the mattress to the bed base with the attachment straps.
14.Hang the control unit at the foot of the bed using the hooks
15.Connect the mattress hoses (Fig: 4) and power cable (Fig: 5) to the control unit then guide it along the bed to the
nearest plug socket and plug it in, taking care not to create a trip hazard.
16.Check that CPR tag is securely pressed down into CPR air outlet.
17.Switch on the rocker switch on the control unit. (Fig: 5)
18.Pump will flash all LEDS before defaulting to AS (Autoset) and dynamic mode
19.The pump setting is set to default to automatic –you do not need to enter the patient weight.
20.The mattress will take up to 45 minutes minutes to inflate. Cushions will take 10 minutes to inflate

Fig: 4 Fig: 5
WARNING:
The power cable must be installed to avoid interference with the articulated parts of the bed or the wheels and to
prevent personnel from tripping up. Failure to install the power cable correctly may result in risk of bodily injury
and/or material damage.
11.2Cushions
1. Place the cushion on the seat with hoses protruding from the back corner.
2. Hang the control unit on the back of the seat.
3. Connect the cushion hoses and power cable to the control unit then guide it to the nearest plug socket and
plug it in, taking care not to create a trip hazard.
4. Switch on the rocker switch on the control unit.
1. The cushion will take up to 5 minutes to inflate. Select the button with a cushion symbol if you want to pair
the pump up with an air cushion. This will ONLY work with the Andway Saiph cushion so please ensure you
use the correct cushion. WARNING> Do NOT use this cushion mode with the pump connected to a mattress –
the pressures will be incorrect and it will cause the pump to alarm

12. Bottoming Out Test
It is important to check that your patient has not bottomed out on the support system. This is where the patient’s
sacrum sinks too far into the mattress and contact pressure from the bed frame is exerted on the patient. To check
for this, slide two fingers between the air cells underneath the patient’s sacrum. The patient should be clear of your
fingers. If the patient has bottomed out, increase the pressure setting on the control unit then wait for 10 minutes
before repeating the bottoming out test. This test does not refer to cushion systems.
13. Settings & operation
13.1 Factory default settings
The default setting for the Polaris ll, Nexus, Tertius control unit is dynamic mode. The control panel on your Polaris
ll, Nexus, Tertius control unit will lock after 30 seconds of inactivity. You can unlock with a single press of the unlock
button and re-lock with a single press of the button (or it will lock automatically after 30 seconds)
The pump setting for patient weight and pressure is automatic. When you switch on, it will default to AS (AutoSet)
so you do not need to enter the patient weight. It will also automatically select Dynamic mode .
13.2 Clinician auto override. Item 1, Figure 2, Section 9
The default setting for the patients pressure setting is automatic. However if a trained clinician decides that his or hers
patients weight or body shape does not suit the automatic selection then they can override the AutoSet setting. Press
and hold the unlock button (Item 1 Figure 2 section 9) for 3 seconds until the lock button LED light goes out then use
the arrow button (Item 4 Figure 2 Section 9) to scroll through the choices available. The first choice is +l which is 10%
firmer than AS, if you press the up arrow again then +ll appears in the LED screen (item 8, Figure 2,Section 9) this is
20% firmer than AS. If you press the up arrow again then is goes to -ll which is 20% softer than AS, and if you press the
up arrow again then -l will appear in the LED screen which is 10% softer than AS. If you press the up arrow again you
return to AS the Automatic pressure setting for your patients weight. Please REMEMBER this setting is based on weight
ONLY and it cannot determine body shape. Short wide patients can require a different setting to say tall thin patients
to double amputees –even though they may weigh the same. A clinician should perform a hand test (section 12) to
determine if the patient is correctly supported.
13.3 Dynamic & Static (CLP) modes. Items 2 & 3, Figure 2, Section 9
The factory default setting for this pump is dynamic (alternating) which means that cells A will inflate for 5 minutes
followed by cells B inflating for 5 minutes whilst cells A are deflated. This is a 10 minute cycle. However a trained
clinician MAY choose static CLP therapy mode. This mode means that ALL the cells remain inflated with any dynamic
or alternating at much lower internal pressure. Press and hold unlock for 3 seconds until the LED light goes out and
then press the CLP therapy mode.
13.4 Care Mode (also known as FIRM or Nursing mode)Item 6, figure 2 section 9
The factory default setting for care mode is OFF. However this mode maybe selected for use when changing dressings,
toileting a patient and other general assistance. This mode will inflate the mattress to maximum and is very firm. The
mattress will NOT alternate Because of this, this mode will automatically switch OFF after 30 minutes use to protect
the patient and should NOT be reused straightaway unless by a trained clinician. To select this mode press and hold
UNLOCK for 3 seconds until the LED light goes out and then select Care. The Dymanic mode LED light will then goes
out. After 30 minutes the Care mode will automatically switch OFF and the Dymanic mode will come back resume by
default.

13.5 Upright boost. Item 7, Figure 9,Section 9
The factory default setting for upright boost is OFF. However this mode maybe selected for heavier patients, patients
who due to their body shape tend to sit lower in the mattress and double/single amputees to give them a boost when
the bed is profiled in sitting/eating/watching TV position. This mode gives about an extra 20% more internal pressure
to support the patient when they are in an upright position. To select this mode press the UNLOCK button for 3 seconds
until the LED light goes out. Then select UPRIGHT BOOST. The UPRIGHT BOOST LED light will light up. This mode has
NO time limit and will remain on until the clinician turns it off. To turn it off, press the uNLOCK button and press the
UPRIGHT BOOST once –and the LED light will go out.
13.6 Cushion mode Item 5, Figure 2, Section 9
The factory setting for this mode is OFF. However if you want select this mode Please read section 11.2 FIRST. You
must NOT use this mode unless the pump is connected to a Andway Saiph cushion . You can cause injury to the patient
if you use CUSHION mode whilst the pump is operating the mattress. To select this mode connect the pump to the
cushion as in 11.2 and then press the UNLOCK button for 3 seconds until the LED light goes out and then select
CUSHION mode. The CUSHION mode LED light will come on. There is NO time limit to this mode and it will remain in
CUSHION mode until the clinician changes it.
13.7 Unlock and factory re-set –Item 1, Figure 2, Section 9
The pump will automatically lock after 30 seconds of inactivity. The LED light will come on and none of the pump
functions will work when locked apart from the alarm mode. To unlock the pump press and hold the UNLOCK button
for 3 seconds. Then you make your function selection before the pump automatically locks after 30 seconds. The
UNLOCK buttons also acts as a factory re-set should you become confused about what is in the pumps memory mode
especially when you swap the pump to a new patient. To reset the pump back to factory settings switch the pump off
at the rocker switch on the side. Now press and HOLD the UNLOCK button and keeping holding it whilst you switch
the rocker switch back on. You will hear three rapid beeps –you may now release the UNLOCK button and the pump
is now reset to factory settings.
14. Alarms

•That the fuse in the power cable has not blown
•That the fuse in the IEC socket on the control unit has not blown
If one, or both, of the fuses has blown check the power cable for damage and replace it immediately if necessary.
If the fault persists, contact your Andway Spica distributor for service repair.

15. Replacing the Air Filter
The air filter must be replaced annually. To replace the air filter, remove the air filter cover (Fig: 8) from the back of
the control unit and replace the cotton filter inside after cleaning any residual dust from the air filter cavity and cover.
Fig: 8
16. Cleaning
16.1 On-site cleaning
When necessary the top cover and base can be cleaned and disinfected on site once the patient has been removed
from the mattress. The following on-site cleaning procedure is recommended for top cover and control unit. Note
that a summary of the below is printed at the foot end flap of the top cover. Do not immerse the control unit in
water.
1. Ensure gloves are worn and all disinfection and occupational health and safety protocols of the facility are
adhered to.
2. Wipe down with a clean cloth using a disinfectant solution comprising of warm water and a neutral detergent
or with a sodium hypochlorite solution (Chlorine 1000 ppm)
3. Proprietary disinfectants may be used provided manufacturer’s instructions are followed.
4. All cleaning agents and disinfectants must be thoroughly rinsed off and the surface dried before storage or
re-use. Failure to do this may result in the accumulation of reagent that could damage the polyurethane
coating, react with the bed frame or negate the bio-compatibility results of the fabric.
16.2 Machine washing / drying
The mattress cover and base can be machine washed. To machine wash the base - all cells and hoses must be
removed. Wash at a temperature up to 71°C (160°F), using normal detergents.
Dry the cover by air drying, spinning or tumbling at temperatures up to 130°C (266°F); do not mangle.
In washing machines, it may be difficult to fully soak the mattress cover. Also, spinning and tumbling may not
remove water trapped between layers. It may be helpful to interrupt the washing or drying cycles to alleviate this.
