INSTALLATION MANUAL
Notes regarding too high air temperatures in the air box:
If in case of high intake air temperature the max. air temperature in the airbox is
frequently or permanently above the limit, the arrangement of air intake has to be
improved or an intercooler has to be installed.
◆ NOTE: Intercooler is not in the supply volume.
Intercooler has to be installed between pressure side of turbo (2) and inlet (3)
into airbox.
16.2.2) Requirements on the intercooler:
- a minimum flow rate of 300 m

/h (390 yd
3
/h) has to be warranted for all
conditions
- the pressure loss must not exceed 15 hPa
■ CAUTION: No additional forces or moments are allowed on turbo charger
or airbox, therefore the intercooler has be supported inde-
pendent and free of vibrations.
