INSTALLATION
1. Position the MON-MEVH, 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 MON-MEVH 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 MON-MEVH, remove the spigot caps, if
125mm ducting is being used. If 100mm ducting is being used, peel out the center 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 MON-
MEVH spigots and to appropriate ceiling terminations.
4. Select the drain spigot required, remove the “Knockout” and connect a suitable drainage system.
