9. Preparation
9.1 Transport
!
CAUTION Injury
Observe the weight of the appliance.
Use suitable transport aids (e.g. sack truck) and
enough personnel for transportation.
!
Material losses
The appliance has a high centre of gravity and low over-
turning moment.
Safeguard the appliance against falling over.
Only set the appliance down on an even base.
!
Material losses
The appliance casing is not designed to withstand strong
forces. Incorrect handling can lead to material losses of
considerable extent.
Observe the information on the packaging.
Only remove the packaging shortly before installation.
Where possible, do not unpack the appliance until it has arrived
in the installation room.
For transport and handling leave the appliance in its packaging
and on the pallet. This enables brief horizontal transport and pro-
vides places to hold on to during transport.
If the appliance has to be unpacked before transportation, we
recommend using a sack truck. Pad the contact surfaces to avoid
damaging the appliance. Secure the appliance using a strap. Pad
the areas between the strap and the appliance, and avoid over-
tightening the strap. Where stairwells are narrow, you can carry
the appliance by the handles on the sack truck or trolley and the
foot of the appliance.
