NOTICE
Risk of damages to the drum motor due to improper cleaning
4
Never use an acidic cleaner together with a chlorinated cleaner since the resulting
dangerous chlorine gases can damage stainless steel and rubber components.
4
Do not apply any acidic cleaners to aluminum or zinc-plated components.
4 Avoid temperatures over 55 °C so that no proteins can be deposited on the surface. Remove
greases at lower temperatures and with suitable cleaners.
4
Avoid water pressures over 20 bar so that no aerosols are created.
4 Maintain a distance of 30 cm between the nozzle and the surface to be cleaned.
4 Do not direct the nozzle directly onto the labyrinth and the seals.
4 Wipe off larger, loose contamination.
4 Pre-clean with water (20 bar, 55 °C).
4 Direct the nozzle down onto the surface at an angle of 45°.
4 For a more thorough cleaning, clean seals, grooves and other recesses with a soft brush.
4 In case of heavy contamination, use a soft brush and/or a plastic scraper together with
spraying water.
4
Clean for approx. 15 minutes using a cold alkaline or acidic agent.
4 Spray off cleaner with water (20 bar, 55 °C).
4 Disinfect with cold agents for approx. 10 min.
4 Spray off with water (20 bar, 55 °C).
4 After cleaning, check surfaces, grooves and recesses for residues.
For scale deposits, we recommend the use of an acidic cleaner 1 to 4 times per month.
If a cleaning with chlorine is permissible, we recommend alkaline cleaners and disinfectants. In
this case, the last disinfecting step can be omitted depending on the degree of contamination.
4 Observe the corresponding certificates at www.interroll.com.
