FITTING THE FAN TERMINAL ((continued)
Fittingg tthe ffan tterminal bby rreccessssingg iinto tthe oouter wwall
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 opening. 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.

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 connectors 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.
