Nilfisk Alto Centix 40 User Manual

Position the holder so that there is plenty of space above 
and below the place where the vacuum unit is to be located. 
Make sure there is a minimum of 500 mm free space above 
the Centix 20 container. Mark the positions for the four 
screw holes with a pen or similar. Then select appropriate 
screws and, if necessary, wall plugs for the type of wall 
surface to which the bracket is to be attached.  Drill the 
four holes for the mounting bracket. The diameter of the 
screw holes in the holder is 5 mm. Fit the mounting bracket 
with the large opening pointing upwards, see Fig. 1. Tighten 
the screws so that the holder is held fi rmly in place (screws 
provided).

The machine is connected with the suction pipe in the uppermost position and 
the exhaust pipe in the lower position. 
This connection should not be glued but can be taped when the unit is serviced at 
a later date. The suction pipe socket can be fi tted to two different points depending on 
the direction in which you would like to install the pipe system. 
To relocate the suction pipe socket, you need to do the following: 
1.   Release the suction pipe socket by unscrewing the four combination Torx screws 

with a Torx T20 or an ordinary screwdriver, Fig. 3.

2.   Pull the socket out of the machine, see Fig. 4.
3.   Loosen the plug blanking off the outlet to which you intend moving the suction 

pipe socket. Unscrew the four combination Torx screws. Remove the blanking plug 
from the machine.

4.   Adapt (move) the suction pipe socket to the new outlet. NB! The socket is marked ”Up”. 

Make sure the socket is fi tted with ÏUpÓ uppermost. Fasten the socket by fi tting and tightening the four screws, Fig. 5.

5.   Fit the blanking plug to the outlet previously occupied by the suction pipe socket. Use the four screws to hold it in place. The 

exhaust pipe must be fi rmly attached to the wall to ensure its connection with the socket does not loosen. Remember that 
you will need to be able to turn the bent pipe in different directions to ensure a suitable pipe layout.  Then connect up the 
exhaust pipe and muffl er, Fig 6. Fit the central vacuum cleaner so that the exhaust pipe is as short as possible, max. 10 met-
res. Take the surroundings into consideration when positioning the exhaust. For this reason, you should always fi t a muffl er. 

For additional information concerning the assembly and installation of the pipe system and low-current lead, please refer to the 
separate assembly instructions supplied with the pipe package.

Position the vacuum unit so that the mounting bracket is directly 
above the wall bracket, see Fig. 2. Lower the machine down on to 
the mounting bracket. Make sure the corresponding bracket on 
the machine is held fi rmly in place by the wall bracket.
