Contamination Defence Air Filter Assembly
A sealed disposable hydrophobic air-filter capsule manufactured in high impact
polystyrene encapsulating a bonded micro glass fibre disc and micro-porous
membrane. 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 0.3-micron particle retention of the filter medium gives not less than
99.985% D.O.P.
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'.
Cleaning Procedure – SAM 1
The collection vessel is constructed from a Medical Grade Polyester Carbonate and is fully autoclavable. Due
to the many methods of cleaning and sterilisation and their effects, reference should be made to the
information sheet Flow-meter MO011 supplied. Solvent-based cleaning agents must not be used.
Overflow Protection Valve
The Overflow Protection valve 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 is recommended the container be replaced before reaching this
level.
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. To prevent frothing anti-foam
agent may be used. Liquid sucked through to the motor will cause damage and invalidate
the warranty.
Cleaning of the Case
The cradle may be removed by tilting forward and pushing up from underneath. It should not be pulled from
the top as this may cause the cradle to stick or result in damage to the cradle.
To clean the outside case of the SAM suction unit – disconnect the unit from the power supply - wipe over
with a clean damp cloth or use an appropriate mild disinfectant solution (following the manufacturers
instructions) - avoiding excessive moisture.
Do not wash the unit under running water or submerge it in water.
Tubing
The silicon tubing used in conjunction with this equipment
is a replaceable item. It should be changed regularly
according to the level of usage and where it has become in
any way contaminated or damaged.
Vacuum Filter Line
The silicon service tube must be connected between the
hydrophobic filter and the vacuum port on the collection
vessel. The tube has an elbow connector on one end for
fitting to the filter and a plain open end for fitting to the
'VACUUM' port of the collection vessel. The tube must be
located under the moulded lip on the rear of the cradle.
