Checking MCB/fuses
MCB/fuses in the front wiring chamber
■ Power circuit MCB/fuse,
Compressor 1 and 2 (see separate
"Connection and wiring diagram"
sheet 2/sheet 3)
Subject to output of heat pump/com-
pressor, see chapter "Specification"
■ Power circuit MCB/fuse, system com-

Danger
Contact with 'live' components
can lead to serious injury from
electric current.
Before working on the equip-
ment, ensure that
the power cir-
cuit is also at zero volt.
Removing fuses does
not switch
the power circuit to zero volt
.
Appliance too noisy
Possible causes:
■ Transport bracket not removed
■ Doors at the front not properly closed
(turn quadrant key as far as it will go).
■ Hydraulic line touches the heat pump
casing.
■ Hydraulic line not connected free of
load and torque stress.
■ Anti-vibration elements for Victaulic
couplings missing.
