Panel Mounting (Flush) - Vent-Axia Lo-Carbon SOLO Plus 427481A Installation And Wiring Instructions

PANEL MOUNTING (Flush)

1. Mark and cut a rectangular hole (190mm x 240mm) through the panel using the back page as a template,
ensuring that there is sufficient space for the product to be installed and that the filter can be removed for
maintenance. IMPORTANT: Be careful to avoid joists and hidden cables.
2. Removing the Front Assembly [A]. Firstly remove the Filter [B] (fig. 2.) by squeezing the clips and pulling. Insert
a small-bladed screwdriver into the slots as shown in figure 3 and push gently to release. Lift the front
assembly slowly from the bottom edge ensuring not to damage the sensor cable (TM model only) attached to
the front assembly and Base Housing [C] (fig. 3/4/11.). IMPORTANT: The cable for the PIR sensor (TM
model only) is not connected as supplied but can be removed by carefully unclipping the cable header
from the Front Assembly.
3. Remove the Spigot Ring [G] from inside the carton and clip over the Spigot Adaptor [E], making sure the lip on
the Spigot Ring locates firmly inside the groove on the Spigot Adaptor (Fig. 6.). 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. 8.). The Spigot can then be rotated and repositioned for side exit using
the same guide rails and retaining screw (fig. 9.). 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
supplied Panel Clips [F] (fig. 10.) allowing enough space between the clip and the flange for the thickness of
the panel (so that the clips can spring open behind the panel).
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 maybe 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 Front Assembly, ensuring that the PIR sensor cable (TM model only) is reconnected to the PIR
sensor PCB (fig. 11.).
11. Switch the mains power supply on and check the fan is operating correctly.
IMPORTANT: Please note that the T and HT(E) incorporate a switch on delay, which will start the fan after 2
minutes for the set timeout period. The delay is only activated via the LS and not via the pull-cord or humidity
sensor (if applicable). If the LS is switched off during the 2 minute period, the fan will remain off.
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 can be removed for maintenance.
2. Insert the wall sleeve with the larger 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.
5. Removing the Front Assembly [A]. Firstly remove the Filter [B] (fig. 2.) by squeezing the clips and pulling. Insert
a small-bladed screwdriver into the slots as shown in figure 3, and push gently to release. Lift the front
assembly slowly from the bottom edge ensuring not to damage the sensor cable (TM model only) attached to
the front assembly and Base Housing [C] (fig. 3/4/11.). IMPORTANT: The cable for the PIR sensor (TM
model only) is not connected as supplied but can be removed by carefully unclipping the cable header
from the Front Assembly.
6. Remove the Spigot Ring [G] from from inside the carton and clip over the Spigot Adaptor [E] making sure the
lip on the Spigot Ring locates firmly inside the groove on the Spigot Adaptor (Fig. 6.). Ensure that the Spigot
Adaptor is firmly located onto the Base Housing and the shutter is still securely fastened and fully functional.
7. Set-up the appropriate speed selection and other features as outlined in Section B SETUP.
8. Using the back page or the Base Housing [C] as a template, mark the fixing hole centres on the wall, carefully
sliding the spigot into the Wall Liner. Secure the Base Housing into position using the screws and fixings
provided ensuring the Skirt [H] is located correctly into the Base Housing (fig. 7.).
9. Ensure the Impeller rotates freely.
10. Select and follow the appropriate wiring diagram in Section C WIRING.
11. Replace the Front Assembly ensuring that the PIR sensor cable (TM model only) is reconnected to the PIR
sensor PCB (fig. 11.).
12. Switch the mains power supply on and check the fan is operating correctly.
IMPORTANT: Please note that the T and HT(E) incorporate a switch on delay, which will start the fan after 2
minutes for the set timeout period. The delay is only activated via the LS and not via the pull-cord or humidity
sensor (if applicable). If the LS is switched off during the 2 minute period, the fan will remain off.
For wall installations a Wall Kit (25 41 02 White / 25 41 00 Brown) can be used.
