Clean the grease separator
• Make sure that no more wastewater can be fed into it.
• Empty the system tank as described under “Emptying” (Chap5 on page 38).
• Disconnect the power supply.
•
Take both inspection covers off the system tank.
Do not clean the grease separator system using a water pressure of more than 5 bar and a water
temperature of more than 50°C. Do not use a high-pressure cleaner on seals. If soap is used for
cleaning, rinse out / extract the residue, as otherwise it could lead to functional problems.
• Clean all components with hot water.
• If present, clean the
SonicControl
sensor.
• Fit both inspection covers on the system tank.
•
Carry out the pressure test and subsequent functional check (see 3.4 Initial filling and pressure test on page
32)).
If all the system components are airtight the grease separator can be put into operation again.
