Removing the burner
Danger
Contact with live components can lead to seri-
ous injury from electric current. Some compo-
nents on PCBs remain live even after the power
supply has been switched off.
■
Never touch the wiring chambers (control unit
and power supply connections).
■
When working on the appliance, isolate the
system from the power supply, e.g. at a sepa-
rate MCB/fuse or a mains isolator. Check the
system is no longer live and safeguard against
reconnection.
■
Prior to working on the appliance, wait at
least 4 min until the voltage has completely
dropped out.
