The Mercury Advance SMARTcare 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.

MERCURY ADVANCE SMARTCARE
1. Introduction
Mercury Advance SMARTcare is an innovative solution in the prevention and treatment of pressure
ulcers. It offers effective dual therapy in a single surface by combining advanced, clinically proven
technologies previously only available in separate hybrid surfaces. Advanced air displacement
technology incorporated into a unique 4 zone configuration now provides more effective pressure
redistribution.
When used in non-powered mode, clinically proven advanced air displacement technology
continually optimises and improves pressure redistribution in response to patient body weight and
movement. The unique ‘air only’ heel zone effectively offloads pressure on the vulnerable heel area.
When used in powered/dynamic mode Mercury Advance SMARTcare delivers pressure relief via
a series of connected alternating foam and air cells. Unencumbered by a top layer of foam on the
mattress, the unique ‘foam in air cell’ construction ensures the delivery of effective pressure relieving
therapy. Dependant on clinical judgement, the alternating function can be operated on either a Low or
High Pressure
The digital Control Unit controls air flow into, or out of the air cells as required according to the
selected operating mode. It also maintains the air pressure within the mattress at the required level
and controls the action of the Audible/Visual Warning System in the event of mains supply failure or
over or under inflation pressure.
2. Quick Reference Guide (Frequently used functions)
This is a quick reference guide for the Mercury Advance SMARTcare System
Product Code MAT1610001
Power Switch Audible Warning Reset
The power switch simply switches the mains power to the Control Unit on and off.
When the Control Unit detects an Audible Warning condition, this can be silenced (see page 5)
and re-set by switching the Control Unit off and then back on again.
CPR Tag and Dual Function Connector
Please ensure that both the CPR Tag located on the umbilical and the Dual
Function Connector are always placed fully home, prior to inflating the mattress.
NB: The mattress will NOT inflate properly should this not be the case.
The CPR Tag is only to be used in the event of a clinical emergency for priority use.
However, disconnecting this function will rapidly deflate air from the mattress
in readiness for transport / static mode.

This symbol when illuminated (the green indicator light) is used to indicate that the equipment is
on or ready for use.
When a patient requires more pressure in the cells, as they may be uncomfortable or feel as
though the support surface is too soft or unstable, then please select a “High” setting (pressure
26mmHg). This must only be used by a trained clinician as often too high pressures can further
agitate certain patient conditions.
When a patient requires less pressure in the cells, as they may be uncomfortable or indeed hyper
sensitive to cell movement or if the patient is still reddening further, then please select a “Low”
setting (pressure 18mmHg). This must only be used by a trained clinician.
This function is used to silence the Audible Warning. The LED will remain lit if the Audible
Warning has been silenced previously, however a fault is still detected. Refer to the power switch
in order to re-set fully. If the Audible Warning continues to sound repeatedly, along with an
illuminated light, then an engineer must be called.
This symbol indicates an “Audible Warning Failure”.
Please see troubleshooting guide below for how to re-set.

4. Installation
4.1 Mattress (This is the applied part type BF)
Place the Mercury Advance SMARTcare 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 Mercury Advance SMARTcare can be used as a pressure reducing mattress for patients at
High Risk of pressure ulcer damage without the need to attach the Control Unit. In this mode, the
Mercury Advance SMARTcare mattress will continuously offload pressures in vulnerable areas
such as the heels.
Alternating Mattress Use
If / When required, the Mercury Advance SMARTcare Mattress can be used as an alternating
mattress system by attaching the Dyna-Form Mercury Advance Control Unit.
No other system should be attached to the mattress as the design settings and internal air
pressure properties of the Dyna-Form Mercury Advance Control Unit are specific to this
mattress only.
The Mercury Advance SMARTcare is a replacement mattress system and should NOT be
placed on top of any existing mattress.
The start-up time from static to dynamic mode is immediate.
4.2 Control Unit
Hang the Control Unit onto the footboard. The mounting hooks swivel to suit the thickness of
the footboard or rail. Connect the umbilical hose to the Control Unit, place the supplied 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) Attach the blue umbilical hose to the Control Unit by connecting the Dual Function Connector
at the end of the umbilical hose to the air inlet connector at the bottom left hand side of the
Control Unit.
(c) Re-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 supplied mains cable to the Control Unit by inserting the “kettle” type connector into the recess
located on the left-hand side of the Control Unit. The mains cable has been designed specifically as a
removable part to aid in easy replacement should it become damaged in use.
Power cables not supplied by Direct Healthcare Group are not recommended for use with this Control Unit.
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 flash 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.

MERCURY ADVANCE SMARTCARE
5.1 Low / High Settings
The Mercury Advance SMARTcare 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.
5.2 Static Hybrid Mode
Should a patient show signs of no longer needing dynamic therapy and depending on clinical judgement, the
Mercury Advance SMARTcare System can be stepped down to a ‘foam in air’ static hybrid mattress.
To do this, turn off the Mercury Advance Mark II Control Unit and disconnect the Dual Function Connector
by pressing the red pump release button.
5.3 CPR Deflation
The CPR system consists of a manually operated tag located on the blue umbilical attached to the Control Unit.
Pulling the red CPR Tag will deflate the mattress air system back to that of a static foam mattress.
Warning: Removal of the Dual Function Connector alone will not expel air as quickly as the CPR Tag.
Do not rely on the Dual Function Connector for CPR, always use the CPR Tag to expel air from the mattress quickly.
Note: After a short period as the Mattress deflates the ‘Low Pressure’ Audible Warning is activated and
can be cancelled by switching the Control Unit off.
5.4 Troubleshooting
For assistance (if needed) in setting up, using or maintaining the Mercury Advance SMARTcare
system, or to report unexpected operation or events, please contact Direct Healthcare Group on the
contact details on the reverse of this manual.
6. Transportation
To change the location of the mattress, press the pump release button on the Dual Function Connector
and allow the mattress to return to its Static Mattress form. Switch off the Control Unit 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 Control Unit 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 Control Unit 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 Control 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.
7.2 Low Pressure Warning
This condition could be caused, for example, by incorrect fitting of the Dual Function Connector,
opening of the CPR Tag or a leak in the Mattress due to a cut or puncture.

Alternating Control Unit
The MAT1610001 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the system can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the system as recommended below, according to the maximum
output power of the communications equipment.

100 11.667 11.667 23.333
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be
estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.
