Cleaning the diaphragm trap
Clean the diaphragm trap at the recommended intervals.
Cleaning instructions:
• Use a mild, alkaline or slightly acidic cleaning agent.
• After cleaning, rinse with clean water to prevent the cleaning agent affecting the diaphragm.
• Remove deposits and contamination on the diaphragm by immersing it in lukewarm water and then rinsing
it with clean water.
• Do not use enzyme tablets or fragrance tablets. When these tablets dissolve and work in combination with
cleaning agents, they can form waxy deposits on the diaphragm. This prevents the diaphragm from closing
fully.
• Never use solvents.
• Never use strong acids with a pH < 1.
• Protect the diaphragm trap against direct exposure to sunlight.
Maintenance
We recommend visually checking the urinal at the intervals outlined below. If odours are starting to
accumulate persistently or the urine discharge is not sufficient, replace the diaphragm trap.
