The Milu In-wall Cistern is a standard in-wall cistern with Odourless by Expella pre-installed inside the cistern. The cistern must be installed by a qualified plumber in accordance with AS/NZS 3500. Installation requires the addition of an electrical power source for the Odourless by Expella system. Have a qualified electrician install a general power outlet (GPO) within 3.5 meters of cable length to the toilet. The location of the GPO should allow future access to the 12VDC power transformer.
Expella recommends that the Odourless by Expella system switches on with the Expella PIR Motion Sensor or with the bathroom light, it can also be shared with the exhaust fan switch or by a designated switch depending on your preference.
The Milu In-wall Cistern fits a 90mm wall cavity with 600mm stud spacing. It is suitable for timber studs only with a 90x45mm stud cross section. The Support Frame securely bolts to the wall studs (600mm spacing) and floor. It supports the weight and external loads for both the concealed cistern and wall hung pan. The Support Frame will transfer the loads from the toilet pan through to the attached wall. The wall must be built rigidly so that flexing is minimised under loading from the toilet. Failure to do so may lead to catastrophic failure of the wall and/or damaged tiles. The studded wall must be constructed using 90x45mm timber sections. Expella takes no responsibility for the construction of the wall. Consult your team of trades to ensure the wall is suitable prior to installation.
The Milu In-Wall Cistern is compatible with wall hung pans that have 180mm or 230mm mounting rod spacing. The cistern should only be used with Milu branded flush plates (see the range on Expella’s website), note that the flush plate requires a 30mm separation between the finished wall and the cistern.
A full installation manual is provided with the toilet suite and further information can be found on Expella’s website.
