Installation and operation instruction

GmbH can be commissioned to carry out the commissioning. In principle 
IGEMA GmbH recommends commissioning the indicator at the same time 
as the boiler (item 8.2). If it is not possible to commission the indicator 
according to item 8.2, the indicator can be commissioned with the boiler under pressure 
and temperature (item 8.3) 
All liquid level gauges are subjected to 100% pressure testing before delivery. In individual 
cases, material settling may occur during transport, longer storage or during assembly. All 
screw connections must therefore be checked for tight fit and appropriate torque (see following 
text). 
8.1 Before commissioning 
Before commissioning, the indicator must be checked for damage and all screw connections 
must be checked for tightening torque 
Md 
max
according to the table (see item 9.5)!
 
The union nuts of the valves must be tightened so that no leakage occurs at the spindle and 
the handwheel / hand lever can still be turned. 
 
Note! 
After commissioning, slight leaks can occur in the valves, but these will reappear 
after a short time due to temperature and pressure.

8.2 Commissioning of the indicator at the same time as the boiler 
 First make sure that the drain valve (4) is closed. Then open the shut-off 
 valves (2, 3) to the stop. The boiler can now be commissioned with the 
 indicator. After commissioning the indicator must be checked for function 
 and leakage. The specified torques and the described tightening 
 sequence (item 9.5) apply. 
8.3 Commissioning of the indicator, when the boiler is under pressure
