Start-up
• Clean the bottom of the toilet bowl.
• Check the mini-check valve and the discharge valve are clean and working correctly.
• Check the water supply hose and the lter of the water valve are not blocked up.
• Check sufcient vacuum (-0.3 bar) is available.
• Open the water supply valve in the water supply piping.
• Press the toilet push button. Pressing the button starts the ushing sequence. The discharge valve opens and
the contents of the bowl are extracted by vacuum. At the same time the bowl is rinsed by water.
• When the discharge valve has been closed water level is restored in the bowl by the closing time delay of the
water valve.
Monitoring the vacuum toilet in the normal operation
• Check the water valve provides the rinse water to the bowl at the same time as the discharge valve extracts
the bowl contents when the push button is pressed.
• Check the push button returns to it´s non-activated state.
• Check after the discharge valve closes, the water valve continues to provide water to the bowl. If the water
valve time delay is correctly adjusted, there should be a pool of water at the bottom of the bowl.
• Check there are no water or air leaks.
! NOTE: Water consumption is dependent on the water supply pressure and the vacuum level.
Preparation for a toilet not to be used for a long period
• Close the water supply valve.
• Run a ush cycle by pressing the push button.
• Close the toilet seat cover.
