• Leaking into waste bottle during static cycle
If liquid drips into the waste bottle when the cell is under pressure and the
static valve is closed, the pressure relief valve is worn and must be replaced
(see Section 5.7
).
• Leaking into collection vessel during static cycle
If solvent leaks into the collection vessel during the static cycle, the static
valve seals are worn and the valve must be rebuilt (see Section 5.8
).
4.3 Gas Leaks
Gas leaks are usually audible. In addition, excessive gas consumption often
indicates a gas leak.
If you suspect a leak, check the following locations: gas supply, rear panel,
solvent reservoir, and interior connections. Listen for leaks and run your hand
over the area to feel for escaping gas.
If you find a loose connection, push the tubing firmly onto its fitting. If the fitting
or tubing continues to leak, replace it.
4.4 Stopped System
• Electrical cables improperly installed
Remove the right-side panel of the ASE 150 (see Section 5.4
). Check that all
electrical cables are seated properly in their connectors on the main PC board
(printed circuit board).
