9.2 Cleaning the fans
The fans must be cleaned at least once a year. Clean the
fan blades with a grease solvent on a cloth (e.g. methylated
spirits) and compressed air if possible. NB! Do not use water.
To take out the top fan:
1. Pull out the electric quick-release contact for the fan
(see Fig. 26).
2. Press down the hook on the spring under the fan housing
and pull the housing sideways (see Fig. 27-1 and 27-2).
Then take the fan housing out of the unit. Take care not
to damage the seal when you pull the fan housing out.
To take out the bottom fan:
1. Pull out the electric quick-release contact for the fan
(see Fig. 26).
2. Undo the safety screw and pull the fan housing out
of the unit (see Fig. 27-1 and 27-2). Take care not to
damage the seal when you pull the fan housing out.
To put the fan back, follow points 1 and 2 in reverse order.
