Checking MCB/fuses
MCB/fuses in the wiring chamber, front, see page: 38
and page 37.
■
Power circuit MCB/fuse, compressor 1 and 2 (see
separate "Connection and wiring diagram" sheet 11/
sheet 12 "11FC2"/"12FC2"):
Subject to heat pump/compressor output, see chap-
ter "Specification"
■
Power circuit MCB/fuse, system components (see
separate "Connection and wiring diagram" sheet 13
"13FC2"):
16 A
■
Control circuit MCB/fuse (see separate "Connection
and wiring diagram" sheet 13 "13FC6"):
6.0 A (slow), 250 V~
MCB/fuse in the wiring chamber, top, see page: 43
■
MCB/fuse F3 on main PCB:
6.3 A (slow), 250 V~
Max. power loss
≤
2.5 W
Danger
Contact with 'live' components can lead to seri-
ous injury from electric current.
Before working on the equipment, ensure also
that
the power circuit is 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 hydraulic connection
missing.
Dismantling / Disposal
Following expiry of the appliance's service life and
when replacing components, observe the statutory
regulations on dismantling, recovery and disposal.
Refrigerants may only be recovered and replaced by
professionals who are qualified and certified for this.
Used refrigerant must be recycled by correct and veri-
fied means.
The dismantling and disposal of components must be
carried out by type. The dismantling of refrigeration
systems may only be carried out by qualified professio-
nals. If permissible, components marked with the
"Green Dot" symbol can be disposed of via the dual
waste collection system [Germany]. Packaging such
as cardboard or foil should be disposed of via the dual
system or recycling trade.
The heat pump is filled with refrigerant R410A. Refrig-
erant R410A is a fluorinated greenhouse gas listed in
the Kyoto Protocol with a global warming potential
(GWP) of = 1925.
