INSTALLATION
1. Position the MULTIVENT, taking into consideration the position of the rooms to be ventilated, the exhaust
position, the drainage position and the electrical services. Ensure there is adequate access for installation and
maintenance. Securely mount the MULTIVENT through the mounting brackets on the casing using the
appropriate anti-vibration mounts, screws, washers, rubber bushes etc.
2. Where the intake and exhaust ducts are to be connected to the MULTIVENT, remove the spigot caps, if 125mm
ducting is being used. If 100mm ducting is being used, peel out the centre of the cap with a screwdriver as
indicated and leave the cap surround in position. To connect ducting to the base intake, use a suitable adaptor
attached using the 4 holes provided.
3. Ducting passing through an unheated roof void should be insulated. Ducting runs should be as straight as
possible and intake ducting should slope downwards from Under the lid. Connect ducting to the MULTIVENT
spigots and to appropriate ceiling terminations.
4. Select the drain spigot required, remove the “Knockout” and connect a suitable drainage system.
