4. Installation Guidelines

4.1 Installing Mattresses
NB. The power unit display default language is English, but can be changed to the language of your choice (please see ‘Setting/Changing Power Unit Display Language’ on page 7).

1. Remove any existing mattress from the bed frame (the QUATTRO mattresses are intended to completely replace the bed mattress).

2. Place the mattress on the bed frame. Ensure the mattress hose exits at the foot end on the right hand side and the coloured cover is uppermost (Fig. 1).

3. Secure the mattress to the bed frame using adjustable straps – pass straps around bed frame mattress platform and secure with the buckles (Fig. 2), allowing for moving components on electric bed frames. This is important as it stops the mattress becoming detached from the bed frame and causing possible injury to the patient. A strap extension kit is available for use with divan beds (part number 11062).
   
   

4. Suspend the power unit from the foot board of the bed having first adjusted the hanger brackets as follows:-
   a) Rotate each hanging bracket away from the pump.
   b) Position the brackets to hang the pump on bed.
   c) Fold the brackets towards the pump when not in use. Alternatively the power unit may be placed on the floor.
   

5. Attach the air supply hose to the power unit by aligning the black line on the air supply hose connector with the black line on the power unit connector and pushing together. Rotate the mattress hose connector clockwise until the green indicator fills the indicator hole on the power unit connector (Fig. 3).
   

6. Plug the smaller end of the power cord into the left hand side of the power unit, and the other end into mains outlet in wall. Ensure that the power cord and tubing cannot become trapped in the bed frame.

7.  Switch the power on at the outlet, and at the side of power unit adjacent to the power cord entry.

8. The system will display STARTING, then INITIALISING whilst the mattress inflates (this will take between 15 – 20 minutes).
   Note : It is important that during the INITIALISING phase the mattress connector is not disconnected from the power unit. If this is done, the power unit must be switched off, MUTE button pressed when the sounder is heard, the mattress connector re-engaged, and the power unit restarted. If UNCALIBRATED is displayed when switched on, the system will continue to operate but should be recalibrated as soon as possible.

9. When a bottom sheet is added to the mattress, ensure that it is left lose to allow the mattress surface to conform with the patient’s body as much as possible.

10.  Allow the mattress to inflate before positioning the patient on the mattress.

11.  Once inflated the system will automatically default to ACTIVE mode. CONTINUOUS LOW PRESSURE therapy can be selected via the THERAPY MODE button (please see THERAPY MODE on page 6). The comfort setting can be adjusted using the up and down arrow buttons (see COMFORT CONTROL on page 6). NB. The power unit will automatically lock 2 minutes after last button operation when running to prevent inadvertent operation of button functions (except MUTE), as indicated by ‘ ‘ on the display screen. Press and hold the MUTE/UNLOCK button until power unit beeps if further button operation is needed (i.e. change of therapy mode or comfort setting).

12.  Place the user manual in a safe place for future use.

4.2 Installing Cushion

The QUATTRO PLUS power unit can be used to operate the B.A.S.E. Sequential alternating air pressure cushion using an optional adaptor, as follows:-

1. Place the cushion on a chair, ensuring that it is placed the correct way up with the BACK labelling (if applicable) facing the back of the chair. Secure cushion to chair using adjustable straps, where available.
2. Connect the cushion adaptor to the power unit, rotating the adaptor clockwise until the green indicator fills the indicator hole on the power unit connector.
3. Connect the air supply hose from the cushion onto the adaptor, matching up the alignment markings (Fig. 4). Ensure that this has been correctly clicked into place, otherwise a leak may occur.

4. Attach the power cord, plug into the mains outlet and switch the power on at the side of power unit adjacent to the power cord entry.
5. Once inflated (approx. 5 minutes) increase the comfort control setting to SEATED using the UP arrow button. NB. If using the power unit from an operating mattress system, first press the MAX. INFLATE button to fully inflate the mattress, then rotate the air supply hose connector anti-clockwise and detach from the power unit to seal the air within the mattress to leave it fully inflated. To reconnect the mattress to the power unit after using the cushion, switch off the power unit and disconnect the cushion adaptor. Re-connect the mattress air supply tubing to the powerunit, and switch on the power unit (operation will automatically default to ACTIVE mode). NB. It should be noted that the use of an alternating air pressure cushion will increase the patient’s seated height by approximately 5cm, and care should be taken to ensure the patient’s comfort and security regarding height of foot and arm rests.

5. Operation Guidelines

5.1 Operation Controls
N.B. Before any operation buttons will function (except MUTE), the power unit must be unlocked – press and hold the MUTE/UNLOCK button until the power unit beeps and the lock symbol clears from the display screen. The operation buttons on the face of the power unit (Fig. 5) provide the following functions
**

THERAPY MODE
Pressing the THERAPY MODE button will toggle between ACTIVE (1 in 4 alternating air pressure cycle) and CONTINUOUS LOW PRESSURE therapy modes. The selected therapy mode is shown on the display screen. The default mode is ACTIVE therapy. To switch to CONTINUOUS LOW PRESSURE mode (once unlocked), press THERAPY MODE button for 2 seconds until an audible tone is heard. The system will then display ‘PLEASE WAIT’ and requires approximately 2 minutes to initialise
COMFORT CONTROL
Air pressure is regulated within each of the cells throughout the cycle so that support, posture and therapy are constantly maintained at optimum levels, in response to patient weight, movement and position. Equalisation of cell pressure automatically takes place at each stage of the alternating air pressure cycle, again to ensure precise pressure and therapy is provided. The automatic default comfort setting is MEDIUM. However, if the patient prefers a firmer or softer mattress, increase or decrease the comfort control setting accordingly (once unlocked) using the UP and DOWN arrow buttons (SOFT/MEDIUM/FIRM). The comfort setting is shown on the display screen. Check periodically to ensure patient support and comfort.

DATA (Used for accessing information only, does not affect mode of operation) Pressing the DATA button at any time switches the display into DATA mode. Use the up and down arrow buttons to scroll through the product data and user information set. Pressing the DATA button again returns the display to the previous mode.

**MUTE/UNLOCK
Press to silence the sounder and to clear the message from the display screen. The power unit will automatically lock 2 minutes after the last button operation when running to prevent the inadvertent operation of button functions (except MUTE), as indicated by ‘ ‘ on the display screen. Press and hold the MUTE/ UNLOCK button until the power unit beeps if further button operation is needed (i.e. comfort setting). The power unit will lock again 2 minutes after the last button operation. NB. After power failure/switching the power off, pressing MUTE cancels the system’s previous settings. When power returns the default setting of ACTIVE mode, MEDIUM comfort setting is invoked. (Note that previous settings are automatically cancelled if the duration between switch off and switch on is greater than 12 seconds. If power returns before a period of 12 seconds has passed and the MUTE button has not been pressed, the system will return to the previous mode of operation.)

MAX. INFLATE
Necessary for some nursing procedures, the MAX INFLATE mode inflates the mattress to maximum static pressure for a period of 15 minutes. After pressing the MAX INFLATE button (once unlocked**) to inflate mattress, the system displays ‘PLEASE WAIT’ followed by ‘READY’ and a 5 second audible tone when maximum pressure is achieved and ‘MAX INFLATE’ is shown on the display screen. After 15 minutes the system automatically returns to the ACTIVE mode of operation.

5.2 Setting / Changing Power Unit Display Language
The power unit display default language is English, but can easily be changed to the language of your choice, as follows:-
a) Plug the power cord into the power unit and into the mains outlet. Switch the power unit on with DOWN arrow button pressed at the same time. Once the power unit has started, release the DOWN arrow button. This enables you to enter the test menu. The power unit will display “TEST MODE CAL” (Fig. 6a).”

6. Care and Maintenance

6.1 Mattress – Exterior Components

• Always keep the cover as clean as is practicable. The material is waterproof and vapour permeable.
• Inspect top cover for signs of damage or wear which could result in the contamination of the interior, e.g. tears, holes, damage to seams or zips, underside staining, etc. The frequency of these checks should be at each decontamination process, i.e. between patients or patient occupancy (or weekly for longer term patients).
• Care should be taken to avoid puncturing cover with objects such as needles, scalpels, pat slides, acrylic nails, etc.
• The cover may be removed and cleaned in accordance with The Revised Healthcare Cleaning Manual June 2009 subject to the following action: Following the use of a detergent and or disinfectant solution the cover should be rinsed with clean water using a clean cloth and allowed to dry.
• Frequent or prolonged exposure to high concentrations of aggressive disinfectant solutions will reduce the useful life of the cover.
• Where high concentration disinfectants e.g. > 10,000ppm chlorine releasing agent (e.g. Haztab or bleach) or combined cleaning/chlorine releasing agent (e.g. Chlorclean, Actichlor) and detergent solutions are used to remove blood or other body fluids, covers should be thoroughly rinsed with clean water to remove any residues. This will help prevent any possible long term compatibility issues associated with disinfectant residues
• Alternatively disinfection may be achieved by laundering cover at temperatures not exceeding 650 C for 10 minutes or 730 C for 3 minutes which may include a chlorine rinse.
• Do not use abrasive cleaners, phenol disinfectants, solvents or alcohol-based cleansers, e.g. Dettol, Phenicol, Hibiscrub, Clearsol, Stericol, Hycoline, as these may destroy the cover materials (* see Care and Maintenance on
• Do not iron.
• Ensure that the cover is thoroughly dried before remaking the bed or placing in storage.

6.2 Mattress – Interior Components

• Check air cells and mattress/cushion interior for signs of damage or contamination, e.g. staining or evidence of fluid ingress. The frequency of these checks should be at each decontamination process, i.e. betweenpatients or patient occupancy (or weekly for longer term patients)
• Care should be taken to avoid puncturing air cells with objects such as needles, scalpels, pat slides, acrylic nails, etc.
• The individual cells can also be wiped clean with a mild disinfectant solution.
• All cells are replaceable and can be obtained easily from Direct Healthcare Group.
• The QUATTRO range of mattresses are fully launderable, but ensure the CPR device is fully closed (i.e. the dial of the CPR device is rotated clockwise until it ‘clicks’ into the closed position ), prior to laundering to prevent water entering the air cells / tubing.

6.3 Power Unit
Always disconnect the power unit from the electricity supply before carrying out maintenance, repairs, servicing or cleaning. To disconnect the power unit from the mains supply and thereby safely terminate operation of the device, remove the mains power cord from the mains outlet wall socket.

Electromagnetic Environment – Guidance

Field strengths from fixed RF transmitters as determined by an electromagnetic site survey,a should be less than the compliance level in each frequency range.b Interference may occur in the vicinity of equipment marked with the following symbol

Note 1 : At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people.

Field strengths from fixed transmitters, such as base stations for radio (cellular/ cordless) telephones and land mobile radio, AM and FM radio broadcast, and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the QUATTRO is used exceeds the applicable RF compliance level above, the QUATTRO should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the QUATTRO.b Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3 V/m.
