Operating ambient air temperature range:
Operating ambient temperature range (Heat pump only): 3 -
40 °C
Range of warehouse storage temperature: -20~60 °C
Set point for the hot water temperature: fixed at 60 °C
3.4 Storing and transportation
As a rule, the unit is to be stored and/or transported in its
shipping package in upright position and with an empty tank.
For transport over short distances, and provided due care is
taken, an inclination angle of up to 20° is permitted. Both
during transport and storage, ambient temperatures of - 20 to
+60 °C are permissible.
3.4.1 Transport using a forklift
When transported by a forklift, the unit must remain mounted
on the pallet. The lifting rate should be kept to a minimum. Due
to its top-heaviness, the unit must be secured against tipping
over. To prevent any damage, the unit must be placed on a level
surface!
3.4.2 Manual transport
For the manual transport, the wooden pallet can be used for
bottom part as long as the carrying straps are secure. Care
must be taken that the maximum permissible inclination angle
of 20° from vertical is not exceeded. If transport in an inclined
position cannot be avoided, the unit should only be taken into
operation one hour after it has been moved into it's final vertical
position.

In Combi Mode the appliance can operate
