For safety reasons, all work in pits must be supervised by a person
outside the pit.
We recommend that you carry out all maintenance and
service work when the product is placed outside the pit.
Pits for submerged sewage and wastewater products may contain
sewage or wastewater with toxic and/or disease-causing
substances. Therefore all persons involved must wear appropriate
personal protective equipment and clothing, and all work on and
near the product must be carried out under strict observance of
hygienic regulations in force.
