  When units are delivered check whether any damage occurred during shipment. If there is damage to the surface 
or outside of a unit, submit a written report to the shipping company. 
  Check that the model, specifications and quantity of the units delivered are as ordered. 
  Check that all accessories ordered have been included. Retain the Owner's Manual for future reference. 
  Do not remove  any packaging before hoisting. If units are not  packaged or  if the packaging is damaged,  use 
suitable boards or packing material to protect the units. 
  Hoist one unit at a time, using two ropes to ensure stability. 
  Keep units upright during hoisting, ensuring that the angle to the vertical does not exceed 30°.
