Further details regarding the individual steps

Opening the heat pump

Danger
Contact with 'live' components
can lead to serious injury from
electric current.
■ Never touch the wiring cham-
bers (for heat pump control unit
and power supplies, see
page 19).
■ When working on the appli-
ance, isolate the system from
the power supply, e.g. at a sep-
arate MCB/fuse or a mains iso-
lator. Check the system is no
longer 'live' and safeguard
against reconnection.
Danger
The absence of component
earthing can result in serious
injury from electrical current and
in component damage in the
event of an electrical fault.
Always restore all earth connec-
tions.
