General Description
HE SAM e.p.s unit is a robust electrically powered fully portable medical suction pump intended for field
and transport use in both Medical facilities and out in the community. It is intended for intermittent operation
to remove secretions, blood or vomit from a patient’s airway to allow ventilation. It may be used continuously
– for the charge of the battery – where considered necessary. It may also be used in a fully occluded condition
for short periods (10 minutes max.) - continuous use in an occluded condition will impair its performance and
is not recommended.
It may be powered by an external DC or AC supply mains, or from its internal 12V battery. he battery may
be charged externally from an external DC or AC supply mains.
A single rotary switch allows the operator to select a number of pre-set vacuum settings between zero and
550+mmHg. Visual indication of settings and conditions is via LCD’s on the control fascia of the unit. A low
battery indicator light shows the status of the battery and there is a light to indicate when the unit is being run
from mains power. reatment can be provided during re-charging.
Higher vacuum levels are generally selected for oropharyngeal suction, and lower vacuum levels for tracheal
suction, children, and infants.
here are no contraindications.
Collection Vessel – the SAM e.p.s unit has been designed to accept a reusable collection vessel or various
disposable liner systems as shown in this manual. he collection vessel sits securely in a tilting cradle. he
standard unit is fitted with the SAM 1 reusable collection vessel. Only collection systems approved by MG
Electric can be used with the SAM e.p.s.
Tilting Cradle – When the unit requires setting on uneven terrain or surface the collection vessel and cradle
may be tilted through 30 increments to maintain a vertical or near vertical position for the vessel and thus
avoiding potential spillage or reduced capacity and allowing treatment to continue. he cradle may be
removed by tilting forward and pushing up from underneath. It should not be pulled from the top as this could
result in damage to the cradle.
Illumination Lamp – If the unit has to be operated in reduced light - the facility to illuminate the operating
area for a selectable period has been provided. he battery life will be reduced when the lamp is used.
Patient tubing and Catheter – Adjacent to the collection vessel is the location for storing tubing and catheter
– in their sterile packaging. These are not supplied with the unit - order MSP120 .

Contamination Defence Air Filter Assembly
A disposable hydrophobic air-filter capsule locates in the unit above the control
panel. his allows a clear flow of air whilst providing an excellent block against
accidental back flow. he Hydrophobic filter prevents costly pump damage or
contamination from liquids being passed through and ensures that jar overfilling
does not result in contaminants being ejected from the suction unit.
he connector, and ‘O’ rings are autoclavable. he filter capsule is disposable and
must not be autoclaved, but renewed in accordance with the recommendations
detailed in the ‘Daily Procedures’.
Fluid Collection Container
Caution! – All collection containers must be
securely mounted in the cradle. he SAM
e.p.s must be located on a firm stable
surface to avoid any spillage or falling.
he vacuum tube from the filter to the collection vessel
locates under the guide lip.
Standard - SAM 1
he SAM e.p.s is fitted with a reusable SAM 1 strong, self-
sealing autoclavable Polyester Carbonate (P.E.C.) collection
container as standard. here is an Overflow Protection float
valve inside the container, which reduces the chance of
liquid being drawn into the pump.
Overflow Protection Valve
he Overflow Protection valve in the SAM 1 is designed to shut off the vacuum to the collection container
when the fluid level reaches approximately 1000ml. When the valve operates, the SAM e.p.s must be switched
off and the full container replaced by an empty one.
It should be noted that even after the valve has shut off, fluid would continue to be drawn into the container
to an extent dependent upon the level of vacuum in the container at the time when the valve closes.
Warning: he overflow valve may not operate fully against frothing; this is why it is important to fit
a hydrophobic filter.
Disposable Liner Systems
he SAM e.p.s has been designed to accept various disposable liner systems. When fitted, protection of the
unit against overflow is entirely dependent upon the correct use of the appropriate liner in accordance with
the manufacturers instructions. Further information may be found in the maintenance and spares section of
this manual. Only collection systems approved by MG Electric can be used with the SAM e.p.s.
Hydrophobic Filters must be used
No liability can be accepted by MG Electric for units affected by the occurrence of overflow when Disposable
Liner Systems are being used.

Supply: 12-24Vdc±10% and 100-230Vac±10%, 50/60Hz.
Running current: 6A max.
Charging current: 1.5A Fast Charge
Fuse rating: 6A external/internal supply and battery.
4A Motor.
200mA Solenoid Valve.
Battery type: Nickel Metal Hydride re-chargeable, 12V, 4.5Ah
Power Supply
he mains input power supply accepts 80 to 264 Vac. at 50/60Hz. If ac. power is supplied to the unit then it
will always be used as the preferred power source during operation.
he unit will also accept a D.C. Input of either 12 or 24 volts. If this input is 12 volts then once again it will
be the preferred power source during normal operation. A 24 Vdc. external source can only be used to charge
the battery as the motor and solenoid valve are both rated at 12Vdc.
If either of the above sources is present then it will be used to charge the internal battery pack. he DC input
range for charging is 11 to 28 volts. hese inputs are fused at 6amps
Battery
he battery – when connected - will be charged when the unit is not in use and when an external power
source is available. When returned to the off state the unit will enter a fast charge condition, which charges
the battery pack. he battery is monitored throughout this process to determine when the battery is fully
charged. he fast charge is then terminated and replaced by a trickle charge to keep the battery fully charged.
he fast charge is terminated when the battery voltage fails to continue rising, thereby indicating that the
chemical process of recharging is complete. For further protection of the battery pack, fast charge will also
terminate if the battery temperature rises above 50 C or if the fast charge cycle has exceeded 3 hours. Again,
to protect the battery, fast charge will not start if the battery temperature is less than 11 C.
he battery fast charge circuit relies on monitoring the temperature of the battery. he fast charge circuit will
not operate should the thermistor connection (the black connector) from the battery not be connected.

If, during use, the battery voltage drops below 9 volts the pump, valve and ultra-bright LED are all turned off.
All four battery LEDs flash red 5 times at 1-second intervals to indicate this condition and the unit enters an
idle state until turned off. his is to protect the battery against over discharging. he battery is fused at 6amps.
In this event, the battery must be re-set by turning the unit OFF.

Operation and Maintenance Manual
Manual 156 - Issue 08 Page 15 of 28
he life of the battery is dependent on its ability to hold sufficient charge to operate the SAM e.p.s. he
chemical process of continual charge and discharge has an effect on that ability over a period. he battery in
time, will reach a point whereby it is unable to hold a sufficient charge to satisfactorily operate the unit and
achieve the performance outlined above. he battery must then be replaced.
Battery Storage
he battery can be stored in a charged or discharged state, and at temperatures between -20°C and +45°C
when installed in the SAM e.p.s. Heat can cause deterioration of the active chemicals and it is better to store
batteries in a cool, clean, dry, environment at a temperature between -20C and +20C. If the battery is to be
stored long-term without charging, changes may occur that can temporarily reduce the battery’s capacity and
voltage under load. Before returning a battery to service, it may be necessary to charge and discharge it, to
bring it up to capacity. If capacity remains low then the battery should be replaced.
Process Control and Service
he main PCB controls and communicates with the other two PCB’s via a single 16W ribbon cable.
he processor contains non-volatile memory that is used to store operational data. his data is divided into 2
sections – one that may be reset and another that remains for the life of the unit.
Data that may be reset includes operational time for each pressure setting, the time the batteries have been in
fast charge and the number of cycles. Data that may not be reset includes ‘life’ operational time of the unit
and the number of data resets.
his data is monitored by the microprocessor and when operation time exceeds 500 hours then the service
LED is illuminated. A service is also requested after 500 fast charge cycles. It should be noted that this does
not affect the performance of the unit in any way and is purely for indication
he data is accessed via the Data port on the main PCB. he Data Capture software MSP1456 is Windows
based and used to download and save this data. It may also be used to reset the data, thereby cancelling a
service request.
For non-windows based systems, a simple terminal emulator may be used to access the data. he Baud rate
is 9600, 8 data bits, no parity. o retrieve the data enter #PRIN followed by carriage return. o reset the data
enter #RESE again followed by carriage return.
Resetting the Unit
If the unit appears not to be functioning correctly, always after a battery disconnection or reconnection then
simply turning the control knob to the OFF position then ON and back OFF will result in a PCB reset.
If the unit still appears not to function correctly, it should be returned to a qualified technician for further
diagnosis.
