INTRODUCTION
1 About This Manual
Arjo strongly recommend that their equipment is only serviced by trained personnel and provide
courses for customers who wish to become licensed to service their own equipment. In no event
will Arjo be responsible for any service performed by customers or third parties.
This manual contains information on maintenance, servicing, repair, troubleshooting and testing for the
range of pressure relief mattress and seat systems shown in Table 1. The information in this handbook
is limited to the mattresses and seat cushions. The pumps for this range of systems are described in the

2 General Description
The mattress replacement, overlays and seat systems identified in Table 1 are designed specifically to
aid in the prevention, treatment and management of pressure ulcers.
They are air-filled, alternating pressure mattress and seat systems powered by air pumps. Some of the
pumps provide an option of microprocessor aided control and sound alarm functions and have LED
indications on the front panel.
The mattresses can be used on standard hospital and normal domestic beds. The seat cushions can be
used on standard hospital and normal domestic chairs.

• Do not use or store the system in direct sunlight.
• Do not use phenol-based solutions to clean the system.
• Make sure the system is clean and dry before use or storage.
Electromagnetic Compatibility (EMC)
This product complies with the requirements of applicable EMC Standards. Medical electrical equipment
needs special precautions regarding EMC and needs to be installed in accordance with the following
instructions:
• The use of accessories not specified by the manufacturer may result in increased emissions by, or
decreased immunity of, the equipment, affecting its performance.
• Portable and mobile radio frequency (RF) communications equipment (e.g. mobile/cell phones) can
affect medical electrical equipment.
• If this equipment needs to be used adjacent to other electrical equipment, normal operation must be
confirmed before use.

3 Mattress Overlay Systems (OL)
A typical mattress overlay (OL) system is shown in Figure 1. It includes a base sheet, alternating and
static cells (which are individually replaceable), a cover, air inlet tubes (with connectors where
applicable) and a Cardiopulmonary Resuscitation (CPR) pull tag (also referred to as a Rapid Deflate
stopper). The cell configurations are detailed in Table 2.
The AlphaXcell Double Mattress system is a double inflatable mattress overlay, which provides static
pressure to one side and alternating pressure relief to the other side. The static and alternating sides of
the mattress can be set up on either side of the bed depending on customer requirements.
The Trancell system is an exception. The cells for the Alpha Trancell system are not individual
replaceable cells but are a one-piece manufactured item and can only be replaced as a complete item.

4 Mattress Replacement Systems (MR)
A typical mattress replacement (MR) system is shown in Figure 2. The MR systems are basically the
same configuration as the OL systems with the addition of a foam base which replaces the normal bed
mattress. The foam base provides a safety and transport function should the air supply fail or the
alternating cells deflate. The cell configurations are detailed in Table 2.

5 Seating Systems
A typical seating system is shown in Figure 3. The seat includes a base sheet, alternating cells, a cover
and air inlet tubes (with connectors where applicable).The cell configurations are detailed in Table 2.
