This is a great manual. It was easy to read and very accurate. The size of the manual is small so email is no problem. I highly recommend it. The manual is very hard to find other than this website.
Whilst this is a photo copy, and some of the pages are a little askew, it was all readable and intact. A real bonus finding an old manual for a classic piece of kit that no other site had.
Great stuff.
It was easy done, and I got exactly what I was looking for.

Venting
The hood is more effective when used in the extraction setting (ducted to the outside). The ducting used must be manufactured from fire retardant material.
Ducting
The ducting must be fire retardant 125mm (5ins) in diameter and the length should be no more than: � 3 metres with one 90° bend � 2 metres with two 90° bend Bends of more than 90° will reduce the efficiency of the hood and reduce the airflow. 1. Remove the two screws on top of the canopy and secure the spigot, fit the spigot (A) on the rectangular air outlet on the top of the canopy using the two screws. Connect the ducting to the ducting spigot (A) using suitable clamps (not supplied). The charcoal filter is not required when installed for extraction. (To remove see maintenance and cleaning section).

3.
Recirculation
The charcoal filter must be fitted for recirculation. When the hood is installed in the recirculation mode, the air is recirculated into the kitchen through the two venting grilles located on either side of the lower Ushaped section.
To fit the recirculation mode
1. Fit the recirculation spigot (F) to the rectangular outlet on top of the canopy and push it down ensuring that the 4 lugs are fitted into the holes. Fit the charcoal filter inside the canopy.
