Adjustment Of The Indicator Liquid Level; Operation; Operating Monitoring (See Sketch Chapter 6) - Igema G Installation And Operating Instructions Manual

8.3 Adjustment of the indicator liquid level

The level of the indicator liquid is adjusted during boiler operation at medium water level.
By repeatedly opening the regulating screw (r) for a short time, enough display liquid is
drained off at the drain opening (q) until the display corresponds to the water level of the
direct water level indicator.
If the deviation is greater, readjustment must be carried out in stages, i.e. with small pauses.
The indicator liquid to be drained off must be collected in a container, taking into account the
safety advice of the working material "indicator liquid". The marking of the working material
is visible on the container.
If, as a result of an error, too much liquid has been drained or too little
has been poured in, proceed as in point 8.2.

Operation

9.1 Operating monitoring (see sketch chapter 6)

The display liquid level must be compared with the water level on the direct water level
indicator at regular intervals.
If not matched, the following causes may occur:
•
Indicator valves (h, j) are not opened.
Open first indicator valve (h) and then valve (j).
•
Main shutoff valves (c, g) are not opened.
Close opened indicator valves (h, j). Opening valves in the following order: c, g, h and j.
•
Condenser (b) is not hot enough; no condensation.
Carefully turn vent plug (a) once and vent condenser (b). Firmly close vent plug again.
•
Operating errors in observing the sequence of opening the valves.
Drain the indicator liquid according to point 8.2.
Subsequent measures according to point 8.2 / 8.3.
•
Liquid level comparatively too high
Adjustment following to point 8.3.
Regularly check tightness of valves (c, g, h and j) and retighten stuffing box if necessary.
