Changing the protection membrane
In case the hydrophobic protection membrane is dirty or overflowed so that the required flowrate is too short, it is advisable to exchange the
protective membrane incl. glass frit, PTFE flat ring and Viton O-ring (set I of spare parts, Part-No. 90F3530).
In case of interruption of the flow, the system has to be checked immediately!
During mountage attention must be paid to absolute cleanliness because impurities may impair the function of the LB-!
By touching the surface with your hand, the protection membrane will be destroyed!
Aggressive condensate possible. Wear safety glasses and protective clothes!
For changing the protective membrane, unscrew the lower part of the liquid stop with the aid of an open-jawed spanner SW17. After this,
take out the O-rings and the glass frit, clean the housing parts and remount the LB-1 as shown below.
For a perfect function it is necessary that the protective membrane is positioned with its surface with fibre glass structure
onto the flat side of the glass frit! When changing the O-ring on the upper part of the LB- (Part-No. 90F400), it is important
to draw up and not to roll up the O-ring. This way, a twisting and a respective leakage are avoided.

Connection of the gas sample line
The connections (3 x 1/8”NPT i) for the gas sample lines are marked on the type plate and in the above drawing. They are executed with
respective screw fittings (see also data sheet 7-1.1) which are screwed gastight into the LB-1 with the aid of PTFE tape.
