Malfunctions caused by residues.
Proper functioning is not guaranteed.
Visually check that there are no metal chips or other residues in the connections.
It is important that metal chips or other residues are blown out.
Install with suitable tools, if required.
Regarding screw connections, use a second spanner to brace against the connection nozzle.
Do not use unsuitable tools, such as pliers.

• Loosen the clamping ring
• Do not damage the O-ring, refurbish if required (oil new O-ring!)
• Fit the metal filter tray and the O-ring and manually tighten by rotating the clamping ring
in a clockwise direction

LEAK CHECK

Check the condition of the system:
• before initial start-up,
• after major changes,
• after repairs,
• after the system has been out of operation for more than one year.
Check the system with 1.1 x the operating pressure using air or an inert gas. The system is
leakproof if the test pressure does not drop after 10 minutes.
Prior to start-up, the oil system with GS Pro-Fi
subjected to leak testing. This may be performed within the framework of leak testing
pursuant to TRÖI and worksheet DWA-A 791, as well as function check of the oil system.
In the event of possible leaks, these must be eliminated, e.g. repeated assembly of the
connections using new gaskets, tightening of the screwed connections.
Observe the notice in MAINTENANCE!
