Page 3: Introductory Notes
INTRODUCTORY NOTES The MVDC & Sentinel Multivent units are designed for simultaneous extract ventilation of multiple wet rooms such as bathrooms, kitchens and toilets. The units use a highly efficient backward curved centrifugal motor impeller set and are designed for continuous 24-hour use. Depending on the model, they feature either 3 or4 settable speeds and can be configured to change speed based on a wide range of sensor or control inputs as depicted below SMV Plus... - Page 4 To maintain the IPx2 rating of the unit, the unit must NOT be mounted with the cover removal slots facing upwards, or at an angle where they are visible from above. All other orientations are acceptable. See the dimensional details below for the mounting hole positions. -Spigot diameters are 125mm...
