8.2.2.3 Heated Line Connections
Heated DEF lines are required as standard to help prevent the fluid within the
lines from freezing during engine operation. The DEF lines are available in a
number of lengths as shown in table 8.5 The number of heated lines requiring
connection by the customer is dependent upon whether a remote PEU is
required. The heated lines are also voltage dependent and so must be
chosen to suit the overall system voltage (12 or 24V).
