• Pull the sealing cap out of the sampler
arm from below.
• When inserting the new sealing cap
from below take care to its orienta-
tion – the two fittings on top are not
arranged symmetrically. When the
sealing cap is inserted properly, both
fittings have to reach through the two
corresponding holes in the sampler
arm.
• The red hose belongs to the fitting with
the red marking, the white hose to the
one with the white marking.
• Retain the sealing cap from below
while reattaching the two hoses to
prevent it from slipping out again.
• Push a new dip tube as far as it will go
into the sealing cap from below.
• Move the sampler arm to the zero
position. (System Preparation 

NOTE
Depending on sample througput and instrument care, an exchange of the sealing cap should be
considered after around 2000 distillations. If steam leaks, the sealing cap needs to be exchanged
immediately.
