TiTre TiTre INSTALLING THE PIPING SySTEM
From DrY to wet
If you wish to replace your conventional (dry) vacuum to an Automatik system, please follow the instructions below.
1. The Automatik system must be installed near the sanitary sewer. If your previous unit was placed to one
end of the building, but the sewer is to the other end, the unit must be reinstalled at a closer range of the
main drain and the pipeline must change its direction as well (Figure E). This will prevent unwanted dust
to cling onto the pipe which will eventually clog the duct.
2. The pipes leading upwards must be slightly higher then the main pipeline to prevent liquids from flowing
back down (Figure C).
3. If short elbows was used to mount the pipeline, these must be taken off. The minumum cornering pipe
must be at least a medium elbow, but an 45 o pipe is recommended for all corners for an optimal efficiency.
4. The inclination of the main pipeline must tilt a little more then using an ordinary vacuum to facilitate the
flow of the liquids.
INSTALLING THE PIPING SySTEM
The following pages illustrate piping diagrams, typical installations and the parts that we recommend
for the optimum performance of your central vacuum system.

• An air outlet leading to outside must always be installed on your unit. Make sure that the evacuated
air does not lead under a carport.
• If your unit includes two motors, it is important to use metal piping and couplings for the air outlet.
• To determine where to locate the wall inlets, use the length of the vacuum hose as a basis, measuring
the furthest point from the wall where the wall inlets are to be installed. Do the same for all the wall
inlets until all areas of the house or building can be reached with the vacuum hose, by moving it from
one wall inlet to another; don’t forget to install one in the garage or outside to vacuum your car.
• If your walls are made of gypsum board, never install a wall inlet in the center of the wall. Drill the
holes for the wall inlets close to a wall stud or a door frame.
• Any screw length can be used if you install the piping as illustrated in Figure A.
• If you install the piping as illustrated in Figure B, make sure to position the small screw in the right place
to avoid that a longer screw goes through the piping.
• Always use a short elbow when connecting the wall inlets (Figures A and B) to prevent long objects (for
example, a pencil) that may have been vacuumed by mistake from blocking the piping further on.
