The manuallyoperated push button is replaced by the activator which reacts through its diaphragm, being triggered when a statichead of 80mm has been built up in the grey water tank. The activator transfers the operating vacuum to the plungerdiaphragm so that the discharge valve opens. After 3 seconds the activator shall close the supply of the operatingvacuum to the discharge valve 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).MaintenanceThe vacuum interface unit does not require any regular maintenance. However, it is advisable for faultless longtermoperation, 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 manytimes (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 (5511200).• Change the ventilator rubber diaphragm (5990385).• Change the mini-check valve (5959902).• Clean the non-return valve (6540549) when applicable.
