envirovent MEV Spider Mechanical Extract Ventilation Unit User Guide
What is it and why is it there?
The MEV is a centralised fan unit mounted in your loft space or cupboard that draws stale, moist air from your bathroom, kitchen, WC and removes it from the property through circular valves mounted in your ceiling.
How will it help?
It will prevent the build up of moisture in the house, remove steam/condensation and odours during bathing and cooking, prevent black mould forming on the walls, behind cupboards etc. It will also help stop the dampness that you can get in your cupboards and wardrobes, on your clothes and furnishings, caused by poor ventilation.
How do I control it?
The MEV Spider operates continuously 24 hours a day at a low rate known as ‘trickle’, to ensure your home is ventilated at the appropriate level. If your MEV is fitted with a humidity tracker the unit will automatically vary its extract rate when it senses increased moisture levels in the property. You can boost the system via the remote control or hard wired wall switch at any time.
For the wired switch, simply click the switch on to put the unit into boost and off to set the MEV back to normal running mode.
In the case of the remote control unit, once the push button is pressed the green LED light will illuminate to show you that the boost has been activated. The boost time is set to 20 minutes as standard. When the battery requires changing, unscrew the switch front cover. The battery is located on the back of the cover. Battery type – 3V Lithium, CR2032.
