General information
The refrigerant provided by Société Trane or Trane UK
Ltd meets all the requirements of our units. When using
recycled or reprocessed refrigerant, it is advisable to
ensure its quality is equivalent to that of a new refrige-
rant. For this, it is necessary to have a precise analysis
made by a specialized laboratory. If this condition is not
respected, the Société Trane or Trane UK Ltd warranty
could be cancelled.
