First push the front-side hose out of
the valve...
... then press the black button down
and push the rear-side hose out
To dismantle the tubings,
pull the frontside hose sideways out of the valve,
then press the black button and
pull the rearside hose sideways out of the valve.
Carefully pull the steam equilibration vessel out of
the bracket to the front, and lay it aside along with the
tubing.
Pull the Novoprene hose that leads from the steam
equilibration vessel off the connector piece under the
roof of the housing.
Cut the new tubings in the same lengths as the old
ones and connect them.
On the old steam release tube there is a curved piece
of PTFE hose. It serves to convey the steam coming
out of the steam release tube to the outside. Take the
PTFE tube off and put it on the new steam release
tube.
Connect the Novoprene hose that will lead to the
connecting piece under the roof of the housing to
the rearside nozzle on top of the steam equilibration
vesssel, put the steam release tube on the frontside
nozzle and the hose leading to the distributor block to
the nozzle near the bottom on the right.
Gently push the steam equilibration vessel into the
bracket from the front. Pull it downwards far enough
to make a sufficient distance to the squeeze valves.
If too little space is left between the upper nozzles
of the steam equilibration vessel and the squeeze
valves, the valve cannot shut the tubes properly.
When doing a distillation, steam will escape through
the pressure outlet rather than get into the sample
vessel. Push the equilibration vessel downwards far
enough to leave a distance of about 3 - 4 cm from
the nozzles to the squeeze valve.
Push the hose that is connected to the frontside noz-
zle of the equilibration vessel into the frontside slot of
the left squeeze valve from the right.
Pressing the button of the squeeze valve, push the
hose connected to the rearside nozzle of the equili-
bration vessel into the rearside slot.
Connect the other end of this hose connection to the
non-return valve.
Push the hose that is connected to the bottom nozzle
of the steam equilibration vessel into the frontside slot
of the right squeeze valve from the right.
Connect the other end of this hose to the steam input
nozzle of the distributor head.
Pressing the button of the squeeze valve, push a
short piece of Novoprene hose into the rearside slot.
Fix the rear panel again, leading the PTFE outlet tube
through the boring.
