Page 3: Maintenance And Replacement Instructions
1. Maintenance and replacement instructions The following described maintenance schedule should be performed by authorized service personnel or in some cases, by the owner themselves. The instructions mentioned must be followed strictly! Before working inside of the tank or on electrical equipment disconnect the power. Avoid direct skin contact with the greywater when cleaning the pre‐filter and the membrane(s). Please use rubber gloves! The following table represents an overview of regular maintenance and replacement intervals. Detailed descriptions are outlined in the corresponding chapters. Maintenance and/or check interval Replacement interval Pre‐filter Check and clean every 3 months ‐‐ Filtration / backwash pump Check every 6 months Replace after 20,000 hrs. running time Floating switch Check every 6 months ... - Page 4 1.1 Pre‐filter The pre‐filter should be checked every 3 months and cleaned every 6 months if necessary. The cleaning interval can then be extended depending on the build‐up of contaminants. The integrated non‐return valve must be checked twice a year and cleaned of any dirt or deposits. Newer Aqualoop versions are being installed with solenoid activated auto‐back‐flush kits attached to the pre‐filter. This means that maintenance is reduced but the pre‐filter should still be checked regularly in case of blockage. 1.2 Suction and backwash pumpset It is recommended that a function test of the pumps is carried out every six months. Each pump is started in the test menu 4. In the case where one pump should fail, the complete double pump unit should be replaced. It is suggested that the filtration and backwash pump set be replaced after 20,000 hrs running time. Please rerun the water‐tightness test to ensure there are no air leaks in the pipework after the replacement of the double pump unit (s. section 9.1). 1.3 Float switch It is recommended that a function test of each float switch is carried out every six months. The float switch is tested by manually inverting it into the two switch positions (Empty=lower position /Full=upper ...

Page 6: Mechanical Cleaning Of The Membrane
Replacing the filter element: It is recommended that the filter element(s) is cleaned or replaced depending on running time and the surrounding air quality. The filter element(s) should be checked every 6 months and should be replaced every 4 years. Detailed information can be found in the separate blower instruction manual (MEDO LA Blower) – available from your local Distributor. Replacing the piston set assembly: It is suggested that the Piston Set Assembly is replaced every 24 months or after 20,000 h depending on the performance of the blower´s pressure and airflow delivery. There is a groove on each Teflon seal of the piston indicating the degree of wear. If one or both grooves are worn away, replacement of the Piston Set Assembly is recommended. Detailed information can be found in the separate blower instruction manual which is included with the blowers. 1.6 Membrane 1.6.1 Mechanical cleaning of the membrane ... -
Page 7: Chemical Cleaning
Attention: a.) Do not loosen the large dark grey nuts located at the top to open the membrane. The reassembling of the cartridge is very difficult without specialised tools. b.) After cleaning please check, that the external ring is locked in the LOCK position! The hollow fibres are now exposed and can be carefully washed with a water jet. Note: Damaged or cracked fibers can simply be knotted by the Installer to seal them and the membrane will then pass the leakage test for quality assurance. 1.6.2 Chemical cleaning Chemical cleaning dissolves biological build‐up (fouling) and mineral deposits (calcium) accumulated on the hollow fibres. Chemical cleaning is done only if the flow is severely reduced < 0.22 L/min = (300 L/day/MEM).
