K-375 Sealing between sample tube and splash protector
We recommend to replace the rubber sealing on the splash protector (connection to the sample
tube) every half year to avoid leakages.
NOTICE
Risk of device damage by overtightening the screw fitting.
• The screw cap shall only be tightened hand-tight.
• Use the open end spanner (11058252)
contained in the standard delivery of
the device to loosen the screw cap
holding the sealing.
• Unscrew the screw cap by hand.
• Carefully take the screw cap with the
sealing away from the device and
replace the sealing along with the inner
fixation ring.
• Reassemble in reversed order.
NOTE
Depending on sample throughput and instrument care it may be necessary to exchange this seal
more often. At least after around 1500 distillations an exchenge should be considered.
