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.

The appliance may be placed in any room, provided the following precautions are taken. The appliance expels hot, very moist air. The rest of the house must be able to easily absorb this moisture. Normally, absorption is only possible in houses where there is very little humidity. Otherwise, the room must have ventilation towards the outside; generally, an open door or window is enough. The capacity of the venting circuit must be at least 150 m3/hour. Check that the air inlet and outlet vents are unobstructed. The best way of evacuating the moisture is through a vent hose to the outside of the building. Use the special 100 mm diameter flexible hose supplied with the appliance connected to one of the air outlet vents with the collar supplied. The unused outlets must be covered. Never connect the air vent hose into an existing discharge pipe or duct, as this could be dangerous, might disturb neighbours and could cause the dryer to malfunction. This product is supplied with a 2.50 metre vent hose, although the maximum length of the vent hose may be: 4 metres with no bends, or 2 metres with 2 bends. Advice: If the hose is long and the room temperature low, the moisture might condense to water inside the hose. This is an unavoidable natural phenomenon. To prevent this water from Iying in the hose or flowing back into the tumble dryer, it is advisable to drill a small hole (dia. 3 mm) in the lowest point of the hose and to place a small container below it.(See picture, point A).
Problems can be encountered in rooms fitted with a very powerful central extractor fan. If you find that drying times are too long, switch off the extractor or close its grille whilst the tumble dryer is in use. A highly effective solution is to simply poke the vent hose through a window or skylight. This might however cause problems in winter because the dryer will draw in very cold (and often also very damp) air through the open window, so increasing drying times and leading to very high energy consumption. If the dryer is fitted next to kitchen units, make sure that the vent hose is not squashed. If the hose is partially squashed, drying efficiency wlll be reduced, resulting in longer drying times and higher energy consumption. If the hose is completely squashed, the safety cutouts with which the machine is fitted may operate.
Condensation discharge through the vent hose
Condensation may be discharged either through a vent outlet provided at the back or through the left or right side outlet. The vent hose collar is placed in the rear vent outlet. Remove the collar by pulling it out of the vent outlet. Screw the collar to the vent hose. Fit the hose into the required vent outlet and place vent covers provided over the unused outlets.
The vent hose must not contain more than two bends when it is placed in position for operation.
Connect the other end of the hose to an opening in a door or window. Fit a suitable shield or point the hose downwards to prevent any rain water and wind from getting in. Rain and wind shields for placing over openings usually consist of valves or movable flaps. Periodically check the shield since strong winds and other factors (rust, dirt) can sometimes prevent it from opening, so causing problems with air venting. If you use a rain shield, check that the openings in it are large enough to allow air to escape. Openings which are too small restrict the flow of air. 4
You should NOT connect the flexible vent hose to, for example, a chimney or flue pipe designed to carry the exhaust from a fuel burning heating appliance.
