∙ 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.

position. (System Preparation
