WARNING

Inspection and cleaning work with the boiler switched on
Serious injuries from automatic startup of the boiler and severe burns from hot

parts and the flue gas pipe are possible.

Therefore:

❒ Only carry out work on the boiler when the main switch is turned off
❒ Always wear protective gloves when working on the boiler
❒ Only operate the boiler using the handles provided
❒ Follow the procedure below when starting and finishing inspection and

cleaning work

Before starting any inspection and cleaning work:
1. Shut down the boiler according to procedure
2. Switch off the main switch on the control cabinet of the electrostatic precipitator

system and secure it against being switched on again

After inspection and cleaning work:

▪ Check that all covers and caps are closed
▪ Switch the main switch on the control cabinet of the electrostatic precipitator

system on again

▪ Turn on the main boiler switch and change to the desired mode
