Intended Use This pressure redistribution mattress and pump is intended to be used in conjunction with an appropriately sized bed frame, as part of an overall pressure ulcer prevention program of care. It can be used safely in static mode (deflated) for static pressure redistribution, or in dynamic mode (inflated) should an alternating pressure support surface be required. This product has been designed to deliver effective pressure reduction to users, when the product is in normal use which is defined by Invacare ® Ltd as when the support surface is covered with a cotton, cotton combination or linen bed sheet, and any one of these would be the only item deployed between the support surface and the user.
1.3
Service Life We estimate a life expectancy of five years for these products, provided they are used in strict accordance with the intended use as set out in this document and all maintenance and service requirements are met. The estimated life expectancy can be exceeded if the product is carefully used and properly maintained, and provided technical and scientific advances do not result in technical limitations. The life expectancy can also be considerably reduced by extreme or incorrect usage. The fact that we estimate a life expectancy for these products does not constitute an additional warranty.
1.4
Guarantee We provide a manufacturer’s warranty for the product in accordance with our General Terms and Conditions of Business. Guarantee claims can only be made through the r elevant specialist dealer.

SECTION 2 – 2 – Basic Basic System Checks
Before commencing any service procedure, the following basic checks should be completed to ensure that the pump fault or failure is not due to an oversight on behalf of the user. 1. Inspect the power cord for any external damage. 2. Visually inspect the pump unit for any damage. Areas to check ar e: - The main case, hanging br acket, CPR connector, IEC power inlet and the display screen cover. 3. Set up the Active Pump and check the following 4. Ensure the power cord is firmly attached and the system is connected to a working power source. Figure 2.1 5. Check the Insert CPR connector is attached to the pump An automatic click will signify a secure connection. Figure 2.2

9. Monitor the pressures for at least one full cycle (10 minutes) 10. Finish testing by switching the pump off and disconnecting the test equipment. 11. If the air pressures fail to meet the specified requirements during the stage of pressure testing, firstly check for any leaks on the test equipment (connections/air cells). If your checks pass without any leaks detected please proceed to the Page 14 Service Procedure Flowchart (Pump is alarming with “Low Pressure” on the display screen) for further indication. Please note that the Air pressure is defaulted at 60mmHg if the pump is turned off and switched back on.
