Expansion Unit

CAUTION
HAZARD OF IMPROPER INSTALLATION Do not install supports in the expansion areas. Do not attach the expansion elements to the supports, as this results in the temperature-dependent expansion of the run not fully compensated. Attach one support in front of the expansion area and one behind it to ensure that the element is fixed correctly. Two support points are provided for each expansion unit. Do not remove the screws without having first installed the two elements adjoining the expansion unit in their final position. Failure to follow these instructions can result in injury or equipment damage.
