the open at a location protected from the wind. Otherwise detector instabilities may occur.
Removing the transport protection
Types of transport protections
There are two types of transport protections:
 Furnace transport protection.
 Water trap transport protection
Purpose of the transport protections
The transport protections prevent...
 ... the furnace section from slipping on its rails while the analyzer is being transported.
 ... the loosely attached water trap from damages while the analyzer is being transported.
