Installation - Vent-Axia Lo-Carbon Scala Plus Series Installation And Wiring Instructions

DESCRIPTION
As standard, the Scala Plus is suitable for panel/wall installations, flush or surface mounting, either in a horizontal
or vertical plane. 100mm ducting (flexible or straight) can be attached using the supplied adjustable spigot,
providing rear or side exit options. For wall installations a Wall Kit (8000000002 White) can be used. An optional
filter is also available (8000000018).
A. INSTALLATION
PANEL MOUNTING (Surface)
1. Cut a 105mm∅ hole through the panel, ensuring that there is sufficient space for the product to be installed
and that the filter can be removed for maintenance.
2. Removing the grille, Firstly remove the front cover by carefully pulling each corner of the front panel until it is
free to be removed from the inner grille (Fig 1). Unscrew the two screws at the bottom of the inner grille. The
screws will remain in the inner grille but will be loose when the grille is ready to be removed (Fig 1). Lift the
inner grille from the bottom.
3. Remove the Spigot Ring from inside the carton and clip over the Spigot Adaptor making sure the lip on the
Spigot Ring locates firmly inside the groove on the Spigot Adaptor (Fig 2). Ensure that the Spigot Adaptor is
firmly located onto the Base Housing and the shutter is still securely fastened and fully functional.
4. Set-up the appropriate speed selection and other features as outlined in Section B SETUP.
5. Attach the ducting to the Spigot and locate into the hole in the panel ensuring the Skirt is located correctly into
the Base Housing. Secure into position using appropriate fixtures (Fig 3).
6. Ensure the Impeller rotates freely.
7. Select and follow the appropriate wiring diagram in Section C WIRING.
8. Replace the inner grille. Replace the front panel.
9. Switch the mains power supply on and check the fan is operating correctly.
PANEL MOUNTING (Flush)
1. Mark and cut a rectangular hole (190mm x 240mm) through the panel, ensuring that there is sufficient space
for the product to be installed and that the filter (If fitted) can be removed for maintenance. IMPORTANT: Be
careful to avoid joists and hidden cables.
2. Removing the grille, Firstly remove the front cover by carefully pulling each corner of the front panel until it is
free to be removed from the inner grille (Fig 1). Unscrew the two screws at the bottom of the inner grille. The
screws will remain in the inner grille but will be loose when the grille is ready to be removed (Fig 1). Lift the
inner grille from the bottom edge.
3. Remove the Spigot Ring from inside the carton and clip over the Spigot Adaptor, making sure the lip on the
Spigot Ring locates firmly inside the groove on the Spigot Adaptor (Fig 2). The Spigot can be repositioned for
side exit installations by removing the screw and sliding the spigot away from the rear of the Base Housing,
carefully observing the guide rails (Fig 4). The Spigot can then be rotated and repositioned for side exit using
the same guide rails and retaining screw (Fig 4). Ensure that the Spigot Adaptor is firmly located onto the
Base Housing in the required orientation and the shutter is still securely fastened and fully functional.
4. Remove the Skirt and pass the supplied screw fully through the flange of the base housing. Then attach the 3
supplied Panel Clips (Fig 5) and partially screw into place until they are properly retained (allowing enough
gap for the panel thickness).
5. Set-up the appropriate speed selection and other features as outlined in Section B SETUP.
6. Attach the ducting to the Spigot and locate into the hole in the panel, ensuring the cable is fed into the Base
Housing and the Panel Clips spring out behind the panel.
7. Secure into position by carefully tightening the Panel Clips. It may be necessary to hold the product centrally
in the hole while tightening so that no gaps are seen once the cover is on. IMPORTANT: If power tools are
used, set them to the minimum torque setting or preferably use a manual screwdriver. Do not over
tighten.
8. Ensure the Impeller rotates freely.
9. Select and follow the appropriate wiring diagram in Section C WIRING.
10. Replace the inner. Replace the front panel.
11. Switch the mains power supply on and check the fan is operating correctly.
WALL MOUNTING (Surface)
1. Cut a 115mm. ∅ hole through the wall, ensuring that there is sufficient space for the product to be installed
and that the filter (if fitted) can be removed for maintenance.
2. Insert the wall sleeve with the smaller diameter sleeve on the room-side and cement both 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 the outside wall.
3. Outside Grille: Using the Back Plate as a template, mark the fixing hole centres on the wall. Drill and plug the
wall and fix the Back Plate into position.
4. Fix the Outside Grille on to the Back Plate (screws provided). Ensure the louvres are pointing downwards.
For wall installations a Wall Kit (8000000002 White) can be used.
