  • Page 11: Individual Ventilation System

    3 Individual ventilation system How the individual ventilation system works. The extractor unit ventilates several rooms in the home through ducts fitted in the kitchen, the bathroom, the WC and all other ‘wet rooms’. These are connected to the central extractor fan system. To ensure there is a good distribution of air, valves are fitted to the openings of the ventilation ducts in the rooms to be ventilated. Air is extracted from the rooms through these valves, while fresh air from outside enters the home through openings, such as grilles in the walls and windows of living rooms and bedrooms.

    5 The Components of the CVE ECO 2 RFT Housing The housing of the CVE ECO 2 RFT is constructed to allow easy replacement of the parts, which makes maintenance and cleaning very simple. The unit can be mounted on the wall or ceiling using the mounting brackets provided. The unit has five air connections. The right port on the unit (1) [see diagram p.14] is the outlet funnel for air extracted and blown outside. The other four ports (2) [see diagram p.14] are for the removal of the air from the home. They are located as follows:...

Insert the screwdriver horizontally in the space provided on the top left and press open the cover. You can then remove the cover by hand. Note: Disconnect the unit from the mains supply before removing the front cover. The blue covers on the unit close off the unused air inlets to prevent leakage of air and ensure that maximum capacity is used.
