7. Installation and Set-Up
7.1 Setting up mattress
The mattress is designed to completely replace any existing mattress which may be in use on a bed.
Remove any existing mattress and ensure that there are no protruding parts or sharp objects on the
bed which could cause damage to the mattress. Lay the mattress on the bed patient surface ensuring
that the air pipe connector is situated on the bottom left hand side of the bed foot end (as viewed from
the foot of the bed).
The mattress can be used as a static mattress without the pump attached,
7.2 Setting up power unit
Whilst holding the power unit, unfold the hanging hooks on the rear of the power unit and hang it from
the beds footboard. If required the power unit can be placed on the floor at the foot of the bed.
Caution: Ensure that the power cable is routed in such a manner so that it cannot
be twisted, trapped, crushed or stressed.
7.3 Connecting mattress to the power unit
Remove the cover of the air pipe connector and connect the air pipe connector to the power unit and
then ensure that the air tubes are free from any kind of obstruction, and are not kinked.
Plug the power cable into a suitable electrical socket and switch ‘ON’ using mains power switch found
at the side of the power unit. All indicators on control panel will light up.The Standby indicator on the
control panel will light up.
Touch the Power button and the system will start inflation
Once the mattress is fully inflated, you can set the mattress to the appropriate setting suitable for the
patient.
Use the + and –buttons to set the patient weight in kg. if the patient weight is between 140 –244kg
set at the highest setting.
The pressure of the mattress can then be adjusted to suit the patient if required.
Caution: The power unit must only be connected to the mattress recommended by
the manufacturer. Do not use it for any other purpose.
Note: Ensure that the CPR valve is set to the closed position.

The Up and Down buttons allow carers to adjust pressures within a safe pre-set range to
provide patients with enhanced comfort or support whilst maintaining a very good level of
protection and therapy. Qualified clinical advice must always be taken before adjusting
mattress pressures.
The service user weight is selected using the +and -buttons to move the pressure by
one step at a time.
When touching the + button, the output pressure will increase to provide a firmer
mattress.
When touching the - button, the output pressure will be decreased to provider a softer
mattress.
