Important handling instructions
• It is advised that two people are used to carry the carton from the
vehicle to the point of delivery.
• Once the carton is in the property, the outer carton is removed first.
Care should be taken when releasing the straps. If a sharp implement
is used make sure the outer carton is not pierced and that the
implement is used in such a way so that it may not cause personal
injury.
• All sharp objects must be covered or the blade retracted after use and
put away in a safe place. Care should be taken when lifting the
appliance from the base and the proper technique for safe lifting of
any heavy object should be strictly observed.
The appliance packaging and base tray are designed so that the
appliance can be tilted backwards onto the outer carton. The carton then
becomes a protective mat.

casing from damage during installation.
The front casing is secured with two screws which are critical to maintain
the case seal and to prevent unauthorised removal (electrical safety).
▶ Always secure the casing with these screws.
Removing the front casing during unpacking.
▶ Loosen the two screws [1] and lift the bottom of the casing clear of
the screws.
