Intercooler
Maintenance
(by authorized specialist personnel)
In order to maintain the heat transfer effi-
ciency of the intercooler, it is necessary to
clean it at regular intervals which depend
on the quality of the coolant used.
For this purpose, dismantle the inter-
cooler. In almost all cases, it will suffice to
clean the individual parts in a hot alkaline
solution, e.g. a 3 to 5% P3-FD solution.
Should hard and firmly adhering scale de-
posits continue to exist a second treat-
ment should be made with a descaling
agent which will not corrode the cooler
core.
Use new gaskets when assembling the
cooler.
Be sure to clean the sealing surfaces
carefully before installing the gaskets.
Observe the specified pressure when
making the hydraulic test.
