7.8 Replacement of the outlet pipe
Description
The outlet pipe (1) of the 2.2 kW compressor element (used on SF 2
+
) and of the 3.7 kW element
(used on SF 4
+
up to S/N API 744 000) contains a plastic insert (3).
Due to the heat of the compressed air, the plastic insert may become brittle after time. It is
recommended to replace the outlet pipe together with the insert when that is the case. Both parts
are available as a kit (outlet pipe set). Consult the Spare Parts List for part numbers.
The outlet pipe set contains two parts:
• The plastic insert (3)
• The metal outlet pipe (1)
