8.2 Commissioning at the same time as the boiler
T
IP
This type of commissioning is recommended by Igema GmbH due to the lower stress on
the components.
Commissioning at the same time as the boiler must be carried out in the same way for all
gauge types. These steps describe the commissioning of a gauge of type LG40-CS with a
drain valve of type AV250 as an example.

Figure 1:
•
Close drain valve (pos. 11)
•
Open the shut-off valves (pos. 12, 13) as far as they will go.
The commissioning of the pressure vessel/boiler with the gauge can now be carried
out.
8.3 Commissioning under pressure and temperature loads
For this type of commissioning, the steps in the operating instructions for the gauge must be
followed. If an action step includes the instruction to close or open the valve, this must be
followed.

Other commissioning for double drain valves
The handling instructions in the operating instructions for the gauges must always be carried
out with both spindles in the case of double drain valves.
