CAUTION
Acidic condensate in sample gas outlet - risk of blockage
Acidic condensate forms in the sample gas outlet.
b
Always lay the sample gas outlet line running downwards so that no condensate
can accumulate.
b
Lay the line end in a suitable disposal device (drain or condensate collection con‐
tainer).
b
Do not kink the line and protect against frost.
The analyzer is fitted with an outlet hose (DIN 8/10) about 30 cm long when delivered.
•
Lay the sample gas outlet in a suitable exhaust duct.
•
The sample gas outlet must be open to the ambient pressure.
Recommendation for lengthening the outlet hose:
To prevent the outlet line clogging, it is recommended to lay a (1) new line starting at
the sample gas outlet of the cell to the disposal location.
To do this, see figure 17, page 20:
1. Open cell cover (loosen 4 screws on the side).
2. Unscrew sample gas outlet line on the sample gas outlet (bracket piece).
3. Loosen fixing of sample gas outlet line.
