Installing the outdoor unit
Transport
Danger
The outdoor unit is filled with refrigerant R290
(propane): Mechanical loading can lead to leaks
in the refrigerant circuit. Where leaks of refriger-
ant occur, there is the risk of explosion or
asphyxiation.
Prevent vibration during transport.
■
Position the outdoor unit carefully after trans-
■
port.
■ When being transported, protect the evapora-
tor on the rear side of the outdoor unit against
mechanical loading, e.g. with cardboard pack-
aging or bubble wrap.
Equipment damaged in transit should not be
■
used.
!
Please note
Shock, pressure and tensile loads can damage
the equipment.
Do not load the appliance top, front and side
■
panels as well as the evaporator on the rear
side of the equipment.
■ In order to avoid damage to the air outlet grill,
always fit the sack truck to the rear side of the
outdoor unit.
Do not damage the evaporator when doing so.
!
Please note
Scratches on the surface coating will lead to cor-
rosion.
■ Only remove the packaging from the outdoor
unit after transporting.
Protect the outdoor unit against direct contact
■
with tools and transporting equipment, e.g.
using cardboard packaging or bubble wrap.
!
Please note
Excessive tilting of the outdoor unit will lead to
equipment damage.
■ Max. tilting angle: 45°
■ Following transport, wait at least 30 min before
commissioning.
Handling using transport aids
Danger
If the transport aids are damaged, the outdoor
unit may fall. Should damage to the refrigerant
circuit occur, there is the risk of explosion or
asphyxiation.
Check transport aids for damage before han-
■
dling.
■ Note the weight of the outdoor unit: See chap-
ter "Weight of outdoor units".
Use the transport aids to lift and transport the outdoor
unit. Wear protective gloves.
The transport aids are each found in the mounting rail
under the outdoor unit. Because of the uneven weight
distribution, there are 4 transport aids on the right-
hand mounting rail.
