Handling
2.1
Transport
• Lift cooling unit only by the casing or with two jack rings (M8)
• Transport the cooling unit only in condition of usage.
• Prior to transport remove the cooling unit and pack it separately
if the complete switch cabinet is to be transported.
Failure to observe these instructions will render the warranty
provisions null and void.

during storage.
• Store cooling unit only in condition of usage.
• The duration of storage amounts to 24 months. The maximum
duration of storage invalite not the respective valid warranty pro-

CAUTION:
After storage below the minimum operating ambient air
temperature it must be guaranteed before start-up, that the
cooling unit achieved permissible operating ambient air
temperature. (see Techn. data sheet)
Failure to observe these instructions will render the warranty
provisions null and void.
2.3
Unpacking
• Prior to and during unpacking make a visual inspection of the
cooling unit to see whether any damage has occurred during
transport. Especially pay attention to loose parts, dents, scrat
ches, visible loss of oil etc.
Any damage must be reported immediately to the forwarding
agent (follow the instructions in "Rules for Damage Claims").
Moreover, the latest edition of the "General Conditions for Sup
