10.1.6 Unhooking the control panel
To make assembly e.g. installation of a charging pump easier, the control
panel can be unhooked.
1. Fold the control panel (KSF) down.
2. Unhook the straps on the left and right of the KSF.
Caution
Hold the KSF to make sure it does not flop forwards.
3. The KSF can be pulled out to the right.
4. Unhook the complete KSF to the right.
Important
Make sure that the KSF can be set down safely in an appropriate
place.
10.1.7 At the end of the maintenance work
Danger
Risk to life due to explosion, fire or escaping flue gas.
Before commissioning the boiler, the parts of the system
through which fuel and flue gas flow must be checked for leaks.
If there are any leaks in the pipelines, the seals must be
replaced. If there are any leaks due to defective components,
the components in question must be replaced.
After finishing the cleaning work, re-install the heat exchanger and
burner.
Check the nominal heat load and exhaust gas values.
