5.3.4 Cleaning the SCROLL cooling fins 

This chapter provides information about cleaning the cooling 
fins in the SCROLL compressor 
 
 
The cooling fins of the SCROLL compressor are an integral part 
of cooling the compressor and must be checked and cleaned 
regularly. (see maintenance plan) 
 
 

Step 

Operation 

Disconnect the compressor from power and com-
pressed air system.  
Secure from unintentional restart. Allow the com-
pressor to sufficiently cool down. 

Remove the copper pipe connection between the 
compressor block (air end) and cooler 

Loosen the screws (Fig. 2) of the cooler fin cover 
and then remove the cover (Fig. 1).  

Loosen the lateral cover of the cooling fins (Fig. 3) 
from the compressor block. 

Thereafter, carefully blow out the cooling fins (Fig. 4) 
or clean with a cloth. 

Complete assembly in reverse order.  

Carry out a test run and a functional check.
