Otto Dig a hole of appropriate dimensions and line a 10 cm thick sand layer at the bottom, grain size 0-5 mm, dampen the sand and level it. Connect the outlet pipe to an inspection chamber with a PVC Ø............. pipe. Connect the waste water col- lecting system to the inlet pipe by means of a PVC Ø............. pipe. Fill OTTO with clean water in order to correctly start the process. Use dampe- Particularly indicated for rain water coming from parkings and mechanical workshops, OTTO is installed between the waste water collecting system and the final discharge to prevent pollu- tion. After installing the plant, verify it under the hydraulic point of view by allowing inlet in. ned sand to fill the gaps around the tank. Build a 5 cm thick light concrete shell on top of the tank, or a reinforced concrete one, in case of drive-on surfaces. Do not forget walk-on and drive-on manholes for inspection. In standard version it is possible to cover the tank with no more than 50 cm thick earth layer. Periodically get a sample of the outlet analysed and evaluate if a cleaning of the system is neces- sary. Also periodically clean the sand trap. Clean the coalescent filter with pressurised water. All removed materials must be dealt with by specia- lised companies. walk-on cover cm 10 light concrete drive-on cover CLS rinforzato INSTALLER ENGINEER (SPECIFICATIONS) USER 44 I N S T A L L A T I O N I N S T R U C T I O N S a n n e x 1 sand cm 10 earth sand earth WALK-ON SOLUTION DRIVE-ON SOLUTION OTTO IS AN OIL AND HYDROCARBONS SEPARATOR WITH SAND TRAP,coalescent filter and automatic closing device. It is meant to be mainly used for rain water from parkings,from petrol stations,from mechanical workshops etc.In deeper detail it consists of: SEWAGE INLET ,with a T pipe to break the inlet flow SAND TRAP It is the first chamber and it is meant for heavier materials sedimentation. COALESCENT FILTER . It can improve the floating process efficiency by enabling smaller oil particles separation, in standard version it is made of plastic AUTOMATIC CLOSING DEVICE It is meant to automatically close the outlet pipe thanks to its particular shape.The outlet flow is stopped when the oil and hydrocarbons storage chamber is full. HYDROCARBONS STORAGE VOLUME It is a space where oil and hydrocarbons are collected until cleaning is performed. www.baygar.com
