NOTE

Information concerning dimensions and positioning of the water connections is provided separately in the Index of dimensional diagrams.
 
Operating state preconditions for cleaning compressors with XC4
NOTE

In order to carry out a successful cleaning procedure that has been tested and is recommended by ABB Turbo Systems, the following preconditions must be met:
-Engine warm from running (engine under full loading as far as possible)
-High turbocharger speed
-Cleaning cycle started according to the following description in Procedure for wet cleaning with XC4

NOTE

If the cleaning container on the filter silencer is used, the detailed cleaning instructions provided on the plate (4) fitted to the filter silencer should be followed.

Use of cleaning container

-The Operating state preconditions for cleaning compressors with XC4
must be met before cleaning can begin.
-Open filling cap (5) on cleaning container (1).
-Fill with clean water.
-Screw filling cap (5) back into place.
-Open valve (6) for about 3 minutes.
-Close valve (6) and check that all the water has been sucked out.
-After cleaning, a waiting time of at least 5 minutes with the engine running must be allowed so that the turbocharger can dry.
 
NOTE

If the cleaning operation is unsuccessful, it can be repeated up to 2 times. If cleaning is still unsuccessful after three attempts and the engine operating values are unsatisfactory, we recommend that the turbocharger be checked and cleaned by an official ABB Turbo Systems service station.
