5.9.1
Fitting the counterflange on the duct
1
Tilt the flange with pipe slightly downwards (1° - 3°) and allow it to protrude approx.
30 mm into the duct so that any condensate can drain off.
2
Now fix the flange with tube properly to the gas duct. Make sure the flange alignment
does not change.
3
If necessary, attach duct insulation to protect the device from heat.
5.9.2
Installing the control unit
The lengths of the lines to the probe correspond to the project planning.
▸
Fit the electronics unit on the 4 fixing points according to the project planning.
DANGER: Hazard through hot, explosive or toxic flue gases
Hot and/or noxious gases can escape during assembly work on the gas duct depending
on plant conditions.
▸
Work on the gas duct may only be performed by skilled persons who, based on their
technical training and knowledge as well as knowledge of the relevant regulations,
can assess the tasks given and recognize the hazards involved.
▸
The system is switched off when working on the gas duct
or
▸
on the basis of a risk assessment, the operator determines the required safety
measures that must be observed when working with the system switched on.
NOTICE:
Device damage due to faulty/missing insulation when the measuring duct is
hot
▸
When the measuring duct is hot, design the insulation of the duct and the flanges so
that the radiant heat of the duct is not higher than the permissible maximum
temperature of the analyzer specification (see Technical Data).
Note:
The probe must not collide with other devices or installations.
Maintain minimum distances to adjacent
objects.
Install at eye level.
