How to operate the pressure lever:
• release the tubing from pressure by pushing the
pressure
lever down
• start the pump and lift the pressure lever step by
step
until the fluid is aspirated and a smooth
flow
is achieved
• under certain circumstances (e.g. new tubing,
elevated
differential pressure, etc.) we recommend
the
user to lift the lever by just one more step
• never over-tighten the pressure lever |
Please
note:
• the setting
of the pressure lever determines the
occlusion
• the optimum
occlusion depends
on tubing
material,
inner diameter, wall
thickness, age of
tubing,
and application conditions
• as a side-effect
the occlusion setting also affects
the
flow rate |
|
|
•
this, however, should not encourage the user to
use
the pressure lever
for flow rate adjustments
because
long-term behaviour is not predictable
•
if, however, the occlusion setting is used to adjust
the
flow rate, the channel-to-channel flow rate
conformity
may lead to good results in the
beginning
of the operation, yet the individual flow
rates
may increasingly diverge at a later stage
•
for an optimum long-term flow rate stability and
channel-to-channel
conformity we suggest using
