Danger
Escaping refrigerant can lead to explosions that
result in very serious injuries.
■
Always use
non-sparking
tools for all work.
■
Do not use any electrical tools, e.g. electric
drills or cordless screwdrivers.
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
wiring chambers.
■
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 that
it is no longer live. Safeguard against recon-
nection.
■
To avoid spark formation:
Prior to working on the appliance, wait at
least 4 min until the voltage has completely
dropped out.
