Preparing the installation of the concealed Helty Flow CMV consists of three steps:

1. creating a rectangular hole in the wall as per the dimensions required by the type of machine to be installed (sheets available on the product page and in the reserved area);

2. installing the EPS housing in the wall (including external vents) and sealing the EPS housing border with flexible polyurethane foam;

3. inserting the CMV unit and connecting to the power supply; positioning the internal cover as selected (plexiglass or sheet metal cover).For more details see the instruction manual (also available in the reserved area).Significantly, the preparatory housing can be pre-integrated into the masonry during the construction phase and later completed with assembly of the CMV unit and cover.
