The manually operated push button is replaced by the activator which reacts through its diaphragm, being triggered when a static head of 80mm has been built up in the grey water tank. The activator transfers the operating vacuum to the plunger diaphragm so that the discharge opens. After 3 seconds the activator shall close the supply of the operating vacuum to the discharge which immediately closes. When the liquid level in the tank has reached approx 80mm, the cycle is repeated. Flushing can occur onlywhen there is sufficient operating vacuum (> - 25kPa). Maintenance The vacuum interface unit does not require any regular maintenance. However, it is advisable for faultless longterm operation, that following actions are done. Every year: Check operation. Clean the tank by running clean water into the tank so that the emptying cycle is repeated many times (if there is a risk of sedimentation at the bottom of the tank, open and clean the tank). Check possible water leakages. Every five years: Open and clean the tank. Change the activator's level diaphragm ( ). Change the ventilator rubber diaphragm ( ). Change the mini-check ( ). Clean the non-return ( ) when applicable.

Discharge does not seal. does not operate. does not operate. Discharge is blocked. Remedy Check that mini-check (6) or vacuum hose are not blocked. Remove blockages from the hose. If mini-check is blocked, replace/clean it. Check that nozzles (17) are not blocked, clean as needed. Loose discharge and check whether rubber diaphragm (7) or suction pipe (8) is blocked. Remove blockages. Check adapter nuts (9) and hose clamps (10) tightness. Loose ventilator and check that float (12) and sealing surface (13) are clean. Clean if needed. Disconnect vacuum hoses (14) from discharge to see if seals. If remains open even when vacuum hoses are disconnected, loose discharge and check whether rubber diaphragm is blocked. Check that ventilator opens each time discharge operates. Check that vacuum hose (15) is connected to the ventilator. Check that ventilator pipe (16) is open. Replace activator. Remove blockages.
