FITTING THE FAN TERMINAL (continued)
Fitting the fan terminal by recessing into the outer wall
If already fitted, remove the four long M4 screws from the top and bottom of the fan terminal. Fit
the terminal into the wall opening previously prepared, ensuring the flue tube seats correctly over
the terminal spigot. When correctly fitted, insert the four screws into the threaded inserts fitted
to the inside of the top and bottom of the terminal. Using a suitable screwdriver, continue to wind
in the four screws from the inside of the box until the fan terminal is held securely in the open-
ing. Alternatively, four holes may be marked in the sides of the fan terminal, and these drilled
through into the brick work. The terminal can then be secured with wall plugs and screws. Apply
a bead of silicone weather sealant, or similar suitable sealant around the top and side edges of
the frame to provide a good seal to the wall, eliminating water ingress.
Note: The recessed fan terminal MUST NOT be cemented into place within the outer wall. The
louvres in the sides of the fan terminal MUST be allowed to vent to the cavity to aid cooling
of components within.
With the terminal fixed into position the wires may now be connected. Attach the green earth wire
to the screw securing the fan earth wire. Fit the two three way connector to the relevant connec-
tors from the fan unit and pressure switch. Check that none of the wires can come into contact
with hot surfaces or moving parts of the fan. Use the cable tie supplied to secure the wires to the
terminal. With all the cables properly connected, fit the terminal cover ensuring the fan outlet is
clear, and secure with the four screws provided. Offer the wire terminal guard cage into position,
mark and drill the relevant mounting holes, and secure into place using rawl plugs and screws.
The terminal guard should be fitted at all times to comply with any byelaws in force.
