CairMax Duo
User Guide
System Preparation
Alternating Use
When clinically required, connect the control unit (if equipped) to
the mattress and operate the CairMax Duo in alternating (dynamic)
mode.
Once connected, allow up to 20 minutes for the air cells to inflate to
operational pressure. The patient may remain on the mattress when
transitioning from Static to Alternating operation.
1
Hang the control unit over the foot end of the bed, using the
inbuilt spring loaded hanging hooks. Ensure it is secure before
use; failure to do so could result in equipment damage.
2
Locate the umbilical air hose at the foot end of the mattress
(it may be stored in the cord retention loops alongside
the mattress). Connect the umbilical connectors to the
corresponding sockets on the side of the control unit. Listen for a
click as confirmation the connector is locked in place.
Straighten any twists in the umbilical air hose to ensure
uninterrupted air flow between the control unit and mattress.
Also ensure
the air hoses are not trapped between the mattress and bed.
Failure to do so could result in an under inflated mattress.
3
Feed power cord through the cord retention loops along the
side of the mattress base. Insert power cord plug into the side
of the control unit, then connect to an appropriate electrical
outlet and switch on mains power.
Ensure the power cord is not under strain; is free from
obstruction; and is stored safely so as not to be a trip hazard.
Periodically inspect the power cord connector for damage
– the plugs are made of transparent plastic for easy visibility.
4
On the control unit, press and hold the Power button for a
minimum of three seconds.
The Power indicator will illuminate green to indicate the system
is operational. While reaching initial operating pressure, all
five pressure setting indicators will flash green. Allow up to 20
minutes for complete inflation.
Once operating pressure is reached, both Alternate and Auto
indicators will illuminate to indicate both alternating mode and
automatic pressure setting are functioning.
