3.3.15 Mounting the WF Set (collection funnel for sample overflow)
To transport from the housing the liquid chemical waste from the measuring unit
separately from the sample overflow, install a second collection funnel (acces-
sory, WF Set). Via the second collection funnel, only the sample overflow from
the overflow vessels is transported out of the housing.
To collect and dispose separately of the chemical waste from the measuring
unit, a suitable (chemical resistant, winterproof) collecting container is required
additionally.
Scope of delivery

 Collection funnel
 Rubber cover for collection funnel
 3 plugs for the 3 openings of the rubber cover
 Sample overflow tube, transparent

Mounting
6 Put the waste tube (2) of the measuring unit into the collection funnel
through the small opening of the rubber cover (4).
The liquid in the waste tube must be able to flow freely (steady slope,
no kinking, no damage).
7 If all liquids are disposed of through a common return line:
Put the sample overflow tubes (3) of the overflow vessels into the col-
lection funnel through the big openings of the rubber cover (4).
8 Close any unused openings of the rubber cover (4) with the plugs pro-
vided so that the housing interior is protected against humidity.
1 Fix the fixing angle bracket at the front cable gland.
2 Insert the sleeve tube of the return line for the sample overflow into the
housing from the outside through the cable gland (9). Inside, the end of
the return tube should be flush with the cable gland (9).
