Installing the Appliance
From Inside
1. Remove the grille, heat exchanger, from the
unit. Note: it is not necessary to remove the
fan assembly from the housing to carry out the
installation.
2. Slide the unit into the mounting hole and
ensure that the flange around its open end is not
held off the mounting surface by the threaded
bushes located in the flange. Remove the
housing assembly and if necessary clear the wall
to suit these bushes and the screws which will
project through them.
3. Offer the housing to the mounting hole. As the
housing is being located in the mounting hole,
feed the electrical supply cable through the entry
hole (located on the top right hand side of the
housing). Note: for the purpose of condensation
drainage a prop is fitted to the underside of the
housing to cause it to adopt a downwards tilt to
the outside wall.
4. Fix the housing assembly in the wall using suitable gap
filler between it and the mounting hole. The housing can
also be fixed to the wall through the holes in the side
using suitable wood screws and wall plugs. Make good
around the internal and external wall faces.
CAUTION:
Ensure the case does not distort
during fixing and making good.
From Outside
1. Offer the frame to the housing and mark its
fixing hole positions on the external wall face.
Remove the frame and drill the wall to accept
suitable wall fixing plugs.
2. Slide the frame over the housing and seal it
against the external wall face using silicone
sealant or mastic.
Fix it in position with suitable
screws.
