Warning
The instrument must only be used in a
fume hood which has the main power
interlocked to the air flow.
Equipotentiality
Terminals identified by the symbol,
bring the various parts of a system to
the same potential e.g. ground poten-
tial, when connected together. Note
that such a terminal must not be used
as a protective earth (ground) connec-
tion.
Hot Surface
Be careful! These surfaces may be very
hot.

11.4 Installation Instructions
The installation should be performed by a service
engineer authorized by FOSS Analytical AB.
The following text refers only to simpler installa-
tion operations and recommendations.
11.4.1 Fume Hood
The instrument should be installed in such a way
as to comply with the regulations issued by the lo-
cal authorities. The Extraction Unit must be in-
stalled in a well-ventilated fume hood (air flow at
least 0,5m/sec.). The Soxtec 2050 Control Unit
and the Soxtec 2050 Drive Unit are not intended
for use in potentially explosive athmosphere and
should therefore be placed outside the fume hood
or according to the instructions when the system
is placed on the laboratory bench. If the system is
installed with cables, wires or tubes passing
through a wall, the opening in the wall must be
sealed.
11.4.2 Installation /Changing
Seals
Note: Check that the hot plate is cold
before installing the seals.
1. Place the seal in your hand (ridge down-
wards).
2. Press the outer rim of the seal into the slot on
the bottom part of the Teflon adapter on the
condenser. Start from the back and work to-
wards the front.
3. Insert seals in all extraction positions.
11.4.3 Seals
The seals should be positioned in the bottoms of
the Teflon adapters, holding the condensers in the
Extraction Unit. The seals are available in choice
of four materials: Viton, Butyl, Teflon and Resell.
To select the correct material for different sol-
vents, please follow the recommendations in table
2.
