2.4 AttachCassettetoPump
Insert the cassette onto the top of the pump, as shown. Align and
gently squeeze the tabs on the cassette to attach to the pump.
NOTE: Once the cassette has been properly placed on the
pump,free-ow(unimpededowduetoforcesnot
generated by the pump) cannot occur because the
cassette disc bottom has been snapped into place.
2.5 RemoveCassettefromPump
To remove the cassette, press both cassette release tabs at the same time
and lift the cassette off the pump.
CAUTION: Do not remove the cassette while the green run light is
blinking.Alwaysplacethepumpinpausemoderst.
Failure to do so will cause (1) part of the history to be
lost, (2) possible under-infusion, and (3) the pump to
sound an alarm when the pump attempts to infuse
medication.
NOTE: ThelterbondedtotheambIT
®
cassettetubingisanair-eliminationlter
(“AEF”). The AEF has two membranes. The larger membrane is a hydrophilic
membrane and the smaller membrane is a hydrophobic membrane. The
hydrophobicmembranewillnotallowwatertoowthroughit.However,in
conjunctionwithsomeotherliquids,suchasorganicliquids,watermaybe
permittedtoowthroughthehydrophobicmembrane.
NOTE: Whenthelterisdry,boththehydrophilicmembraneandthehydrophobic
membrane will allow air through. Once the hydrophilic membrane comes in
contactwithwater(is“wetted”)airwillnotowthroughthemembraneuntil
the bubble point is reached. (The bubble point is the pressure required to force
air through the wetted hydrophilic membrane).
NOTE: Due to the nature of the hydrophilic membrane, it is important to prime the
ambIT

lteredcassettewithoutgettingwaterinthelter.Thiswillallowairto
owthroughveryeasily.Oncethelteriswet,itmaybemoredifculttoprime,
becausetheairhasamuchsmallerareatoowoutof(airwillonlyowoutof
the smaller hydrophobic membrane).
