Unloading and handling

Note
Before unloading, have the recipient check the con-
signment 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
To prevent appliance damage, observe the fol-
lowing when unloading and handling the heat
pump.
■ Never put weight on top of the appliance.
■ To protect the paintwork, wrap the lifting gear
(such as ropes, cross beams) and place pad-
ding between the heat pump and lifting gear.
Observe correct weight distribution when lift-
■
ing. Due to the heat exchanger, the heat pump
centre of gravity is on the l.h. side.
■ Avoid impact and shocks to prevent damage
to the internal pipework of the heat pump.
■ To protect the refrigerant circuit, do not tilt the
compressor too far: Max. tilting angle of the
heat pump 30°.

No charging with oil or refrigerant required. The heat
■
pump has been charged with oil and refrigerant at
the factory.
