Vent-Axia Lo-Carbon Quadra HTP, Installation And Wiring Instructions, Page: 4 / 14

A. INSTALLATION
A Backdraught Shutter Assembly is supplied. It is packed inside the product during transport. It is
designed to block the duct when the fan is off in order to prevent cold draughts from outside
entering the building. If you are going to set the fan up to extract air continuously (constant trickle),
you do not necessarily need it. To use it, push it on to the end of the exhaust Spigot with the
hinges on the flaps vertical (
fig.1 ).
IMPORTANT: Be careful to avoid joists and hidden pipes or cables when cutting or drilling holes.
SURFACE MOUNTING (PANEL/CEILING)
1. Remove the Front Cover Assembly by slackening the 2 Cover Screws by 2 turns ( fig.2.) Lift
the Cover Assembly away from the bottom edge then the top edge .
2. Cut a

105mm hole and suitable screw holes in the panel, ensuring that there is sufficient
space for the product to be installed and that the optional Filter ( fig.3 ) could be removed for
cleaning. The cardboard fitment in the packaging can be used as a template.
3. Set-up the appropriate speed selection and other features as outlined in Section B SETUP.
4. Remove the small Internal Cover that covers the Terminal Block in the top right corner ( fig.3 ).
5. Attach the ducting to the Spigot and locate the Fan into the hole in the panel. Feed wiring
through the hole in the Chassis next to the Terminal Block as you do so.
(fig. 4)
6. Secure into position using appropriate screws and rawl plugs.
7. Select and follow the appropriate wiring diagram in Section C WIRING.
8. Replace the Internal Cover over the Terminal Block.
9. Ensure the Impeller rotates freely.
10. Replace the Front Cover Assembly and tighten the two screws.
11. Switch the mains power supply on and check the fan is operating correctly.
SURFACE MOUNTING (WALL)
For through-the-wall installations, a Wall Kit (25 41 02 White / 25 41 00 Brown) can be used.
1.
Remove the Front Cover Assembly by slackening the 2 Cover Screws by 2 turns ( fig.2.) Lift
the front assembly away from the bottom edge then the top edge.
2. Cut a

117mm hole through the wall, ensuring that there is sufficient space for the product to
be installed and that the optional Filter ( fig.3 ) can be removed for maintenance. The
cardboard fitment inside the packaging can be used as a template.
3. Insert the wall sleeve with the larger diameter sleeve on the room-side and cement the ends
into position flush with the wall faces. The wall sleeve should be angled downwards, away
from the Fan, to allow any condensation to drain to outside.
4. Outside Grille (available separately): Using the
Grille’s Back Plate as a template, mark the
fixing hole centres on the wall. Drill and plug the wall and fix the Grille into position. Ensure
the louvres are pointing downwards.
5. Set-up the appropriate speed selection and other features as outlined in Section B SETUP.
6. Remove the small Internal Cover that covers the Terminal Block in the top right corner ( fig 3 ).
7. Using the Fan Chassis as a template, carefully sliding the spigot into the Wall Liner, mark the
fixing hole centres on the wall.
8. Drill and plug the wall using the fixings provided.
9. Feed the wiring through the hole near the Terminal Block ( fig. 4) and secure the Fan into
position using the screws provided.
10. Select and follow the appropriate wiring diagram in Section C WIRING.
11. Replace the Internal Cover over the Terminal Block.
12. Ensure the Impeller (
fig.3 ) rotates freely.
13. Replace the Front Cover Assembly and tighten the two screws.
14. Switch the mains power supply on and check the fan is operating correctly
