Unloading and handling
Note
Before unloading, check the consignment for damage.
Note down any damage on the delivery note and notify
the haulage contractor.
■
Lifting gear, such as slings and cross beams, must
be provided on site.
■
The lifting capacity of each sling and that of the cross
beam must be at least equal to the shipping weight.
See "Specification".
■
Only use suitable equipment for unloading the lorry;
see the following chapter.
!
Please note
Incorrect unloading and transporting can result
in damage to the appliance.
■

put weight on top of the appliance.
■
Protect the paint:
Wrap the lifting gear (such as ropes, cross
beams) and place padding between the heat
pump and lifting gear.
■
Observe correct weight distribution when lift-
ing. Due to the heat exchangers, the heat
pump's centre of gravity is at the back, by the
hydraulic connections.
■
To protect heat pump pipework:
Avoid bumps and shocks.
■
To protect the refrigerant circuit:
Avoid major slopes of the compressor.
