DYNA-FORM MERCURY ADVANCE
The mains plug should be turned off and removed from wall socket as a means of isolation.
Plug the mains cable into a suitable 230v mains socket and switch on the Control Unit using the on/off
switch.
After the Control Unit has been turned on both the "High "and the "Low" lights will fl ash together
intermittently until the Control Unit has attained its initial operating pressure. Once the Control Unit has
attained its initial operating pressure the "Low" light will stay on constantly and the mattress is ready for
use.
6.1 Low / High Settings
The Dyna-Form Mercury Advance Mattress, in Alternating Mode, has two pressure settings. The initial
setting that the control unit will revert to upon set up is "Low". The "Low" comfort setting is ideal for the
lighter patient or those who feel discomfort when on a normal alternating air type mattresses system.
However, for patients with existing pressure damage or those at Very High Risk, it is recommended that
dependant on the clinical judgement of the clinician, the "High" setting is activated by pressing the +/-
button once, which is located on top of the Control Unit.
In "High" Mode the Control Unit attains more of the characteristics of an alternating air mattress system
whilst still utilising the advantages of the static foam inserts. Repeatedly pressing the 'mode' button
enables the Low & High modes to be selected in turn.
6.2 CPR Deflation
The CPR system consists of a manually operated button located on the Air Inlet connector attached to
the Control Unit. By pressing the Red Button, which will release the connector locking system, the user
can remove the connector unit which will deflate the mattress air system back to that of a static foam
mattress.
Note: After a short period as the Mattress deflates the 'Low Pressure' Audible Alert is activated and can be
cancelled by switching the Control Unit off.
6.3 Terminating Operation
The active therapy can be terminated and returned to a static pressure redistributing mattress by
switching off the On/Off switch.
6.4 Troubleshooting
For assistance (if needed) in setting up, using or maintaining the Mercury Advance System, or to report
unexpected operation or events, please contact Direct Healthcare Group on the contact details on the
reverse of this manual.
5.4 Fire Evacuation System (If Applicable)
The Dyna-Form Mercury Advance can be fitted with an optional fire evacuation system. In the event of an
evacuation occurring, the following steps should be taken to provide the safest possible transport of the
user:
1. The Dyna-Form Mercury Advance Fire Evac system has clearly marked instructions on the foot and
head for ease of use.
2. Open the zips at the shortest ends of the mattress (head end and foot end) to gain access to the Fire
Evac harness system.
3. Pull out harnesses from the mattress and remove the patient securing straps.
4. Place patient securing straps around both the mattress and the patient, adjust the straps accordingly to
ensure the patient is secure.
5. Drag both the mattress and the patient on the floor to an area of safety.
