SERVICE MANUAL
The Dyna-Form Mercury Advance is a pressure relieving mattress suitable for use with patients at VERY HIGH RISK
of pressure ulcer damage.
Offering high levels of patient comfort, this unique system has the facility to “step up” to that of a dynamic mattress when clinically
required. Similarly, the mattress’s function can be downgraded as the patient’s condition improves.
These features make it particularly beneficial for use within the patient’s home or palliative care environment and help reduce
logistic and decontamination costs. The clinical benefits of a single system are equally applicable to those of a modern hospital
setting. A higher maximum weight capacity, up to 40 stone / 254kg, allows the product to meet the modern challenges of
those heavier clients. All component parts are interchangeable and replaceable, maximising product life and reducing
environmental impact.

1. Introduction
The Mattress consists of a foam head cell and series of 14 transverse air cells, each containing a unique
foam profiled insert, which are in turn held within a foam U Core, all protected by a vapour permeable
waterproof cover. The single head end cell and the formers consist of foam only. The transverse cells are
arranged into alternate pairs of A and B cells which are filled and emptied in sequence.
In Static Mode, the mattress attains the pressure reducing properties of the Dyna-Form Mercury
static foam mattress (details available on request), whilst in Alternating Mode the mattress is able to
offer similar properties to a pressure relieving dynamic system.
The digitally controlled Power Unit controls a pump that allows air to flow into, or out of the air cells
as required according to the operating mode selected. It also maintains the air pressure within the
mattress at the required level and controls the action of the audible/visual Audible Warning System in
the event of mains supply failure or over or under inflation pressure. A CPR Valve located at the pump
end of the umbilical hose permits the rapid deflation of the Mattress in an emergency.
2. Quick Reference Guide (Frequently used functions)
This is a quick reference guide for the Dyna-Form Mercury Advance System
Product Code MAT/MERADV/198/88/15
Power Switch Audible Warning Reset
The power switch simply switches the mains power to the pump on and off.
When the pump detects an Audible Warning condition, this can be silenced (see page 5)
and re-set by switching the pump off and then back on again.
CPR Valve
Please ensure that the CPR connector is always placed fully home, prior to inflating the mattress.
NB: The mattress will NOT inflate properly should this not be the case.
The CPR connector is only to be used in the event of a clinical emergency for priority use.
However, disconnecting this function will cleverly deflate air rapidly from the mattress in
readiness for transport / static mode.

4. Installation
4.1 Mattress (This is the applied part type BF)
Place the Dyna-Form® Mercury Advance Mattress directly on to the bed platform ensuring that the
Blue multi-stretch waterproof cover is on top and that the umbilical hose is located at the left hand
corner at the foot end of the bed. Note: The umbilical hose can be located inside the cover under
the “Open Here for Air Inlet” printed in the bottom left hand corner of the mattress.
Cover the Mattress with a loose fitting sheet.
Static Mattress Use
The Dyna-Form® Mercury Advance Mattress can be used as a pressure reducing mattress for
patients at High Risk of pressure ulcer damage without the need to attach the pump.
Alternating Mattress Use
If / When required, the Dyna-Form® Mercury Advance Mattress can be used as an alternating
mattress system by attaching the Dyna-Form® Mercury Advance Power Unit (Pump) system.
No other system should be attached to the mattress as the design settings and internal air
pressure properties of the Dyna-Form® Mercury Advance Power Unit (Pump) are specific to
this mattress only.
The Dyna-Form® Mercury Advance is a replacement mattress system and should NOT be placed
on top of any existing mattress.
The startup time from static to dynamic mode is immediate.
4.2 Power Unit (Pump)
Hang the Power Unit (Pump) onto the footboard. The mounting hooks swivel to suit the thickness
of the footboard or rail. Connecting the Umbilical Hose to the Power Unit (Pump), place the 3-pin
electrical plug into the wall outlet and switch on:
(a) Open the zip located at the bottom left hand side of the mattress and pull out the Blue Umbilical hose.
(b) A ttach the Blue Umbilical Hose to the Power Unit (Pump) by connecting the air connector
at the end of the Umbilical Hose to the air inlet connector at the bottom left hand side of the
pump. Ensure that the Red CPR Release button is located on top of the Air Inlet connector after
connection is complete.
(c) R e-close the zip as far as possible without clamping the Blue Umbilical Hose to ensure the
mattress and air cells are sealed within the cover.
(d) Shut down is the reverse of items a, b & c above.
5. Operation
Attach the mains cable to the pump by inserting the “kettle” type connector into the recess
located on the left hand side of the pump. The mains cable has been designed specifically as a
removable part to aid in easy replacement should it become damaged in use.
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 Power Unit using the
on/off switch.
After the pump has been turned on both the “High “and the “Low” lights will flash together
intermittently until the pump has attained its initial operating pressure. Once the pump has
attained its initial operating pressure the “Low” light will stay on constantly and the mattress is
ready for use.

DY N A - F O R M M E R C U RY A D VA N C E
5.1 Low / High Settings
The Dyna-Form® Mercury Advance Mattress, in Alternating Mode, has two pressure settings.
The initial setting that the pump 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
pump.
In “High” Mode the pump 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.
5.2 CPR Deflation
The CPR system consists of a manually operated button located on the Air Inlet connector
attached to the pump. 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 Warning is
activated and can be cancelled by switching the Power Unit off.
5.3 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 Services on the contact
details on the reverse of this manual.
6. Transportation
To change the location of the mattress, remove the Umbilical Cord and allow the mattress to
return to its Static Mattress form. Switch off the Power Unit (Pump) using the on/off switch and
disconnect the electrical supply cable from the mains socket. The mattress can now be moved to
a new location where it must immediately be reconnected to the mains electrical supply and the
Power Unit (Pump) switched back on. Once the Mattress has been refilled, the ‘Alternating’ mode
will automatically revert back to the Low setting and should be reselected to High should this be
desired by the clinician.
Warning: The Mattress will not ‘alternate’ when disconnected from the Power Unit (Pump)
and /or the mains electrical. Also refer to environmental conditions section at rear of this manual.
7. Warnings
Warning conditions are indicated by a flashing red display accompanied by an audible warning.
In each case the user should respond by turning the Power Unit’s switch off and investigating the cause.
7.1 High Pressure Warning
This condition could be caused, for example by a kinked Umbilical Hose or visitors,
and others, sitting suddenly on the Mattress.
