MGE UPS Systems SAM Operating And Maintenance Manual page 6

External Power – When illuminated - indicates that external power is connected. The unit may be used whilst
being charged but the charging process will provide trickle charge only.
Filter Housing – The unit MUST be fitted with a MGE Hydrophobic filter capsule to ensure proper protection.
Contamination Defence Air Filter Assembly
A disposable hydrophobic air-filter capsule locates in the unit above the control
panel. This allows a clear flow of air whilst providing an excellent block against
accidental back flow. The 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.
The connector, and 'O' rings are autoclavable. The 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. The SAM
e.p.s must be located on a firm stable
surface to avoid any spillage or falling.
The vacuum tube from the filter to the collection vessel
locates under the guide lip.
Standard - SAM 1
The SAM e.p.s is fitted with a reusable SAM 1 strong, self-
sealing autoclavable Polyester Carbonate (P.E.C.) collection
container as standard. There is an Overflow Protection float
valve inside the container, which reduces the chance of
liquid being drawn into the pump.
Overflow Protection Valve
The 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: The overflow valve may not operate fully against frothing; this is why it is important to fit
a hydrophobic filter.
Disposable Liner Systems
The 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.
Hose Connections for differing collection systems
The cradle may be tilted through 30 for easy removal and changing of the collection container and avoiding
potential spillage.
