of their training, knowledge and practical experience, can guarantee that they carry out evaluations or tests in a
professional way in the respective field.
– Check on the inner walls of the sludge trap and the grease separator.

Clean the grease separator

• Make sure that no more wastewater can be fed into it.
• Empty the system tank as described under „Emptying" (Chap4 on page 13).
• 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 residues, as otherwise it could lead to functional problems.
• Clean all components with hot water.
• Fit both inspection covers on the system tank.
• Carry out pressure test and then a functional check (see 3.3 Initial filling and pressure test on page 12)).
If all the system components are airtight, the grease separator can be put into operation again.
