2.
Opening the wiring chamber.
3.
Check fuses. Replace if necessary.
Danger
Incorrect or improperly fitted fuses can lead
to an increased risk of fire.
■
Insert fuses without using any force. Posi-
tion fuses correctly.
■
Only use structurally identical types with
the same response characteristics.
Danger
Removing the fuse does
not switch the power
circuit to zero volt
. Contact with 'live' compo-
nents can lead to serious injury from electric cur-
rent.
Before working on the equipment, always
ensure that
the power circuit is also at zero
volt.
Appliance is too noisy
Possible causes:
■
Casing door is not closed tightly: See page 13.
■
Hydraulic lines and electrical cables are touching or
coming into contact with other components of the
heat pump, e.g. the casing.
