Checking fuses
For fuse locations, see from page 28.
■ Fuse F1 is located on the mains ter-
minal of the heat pump control unit.
■ Fuse F3 is located on the main PCB.
■ Fuse F101 is located on the AVI PCB.
Fuses F1 and F3:
■ 6.3 A (slow, H), 250 V~
■ Max. power loss ≤ 2.5 W
Fuse F101:
■ 1.0 A (slow, L)
■ Max. power loss ≤ 2.5 W
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 current.
Before working on the equip-
ment, always ensure that
the
power circuit is also at zero
volt.
