Page 2: Installation Instructions
INSTALLATION INSTRUCTIONS Dimensions Free membrane area: 0.2 m² Materials: Membrane: EPDM (ethylene propylene diene rubber) TPU (thermoplastic polyurethane) Base plate: Polypropylene (PP-GF) Frame: Polypropylene (PP-GF) Gaskets: EPDM The distance between the diffusers on the distribution pipe (connection hole axis) should be at least 280 mm and must not exceed 1,000 mm (differences possible on request). - Page 3 ® depending on version). The distribution pipes must be levelled to a maximum of ± 10 mm. For installation on round pipes with Supratec supporters, the pipe clamps must be tightened with torque of 10 Nm (M10); 20 Nm (M12). The surface pressure that this produces ensures that installation is distortion-free.
- Page 4 Type 'AS': Installation on round pipe The OXYFLEX - MF1100 type 'AS' membrane plate diffuser is attached to a round pipe made from stainless steel ® or plastic using a clamp saddle. Bore holes with a diameter of Ø 25 mm are drilled in a central position on top of the round pipe. The top part of the clamp saddle that is welded to the OXYFLEX - MF1100 membrane plate diffuser has a supply air pipe connection.
- Page 5 Type "SA": Fitting to square pipes with holes at side The OXYFLEX - MF1100 type 'SA' membrane plate diffuser is secured using side adapters to square pipes with ® two bore holes in the side. A flat gasket made from EPDM is inserted between the square pipe and the side adapter or the square pipe and the counter piece.

Deviating procedures are possible in consultation with Supratec. Bubble pattern The bubble pattern should be assessed no sooner than when the above-described run-in of the diffusers has been completed. - Page 7 (for more than 40 hPa compared to commissioning), Supratec should be consulted immediately. Particularly in the case of systems that are operated intermittently, there is a risk that damaged diffusers can allow the ingress of live sludge into the entire pipework system.
