2AC9932-S INSTALLATION

• Repeat steps 1 to 5 to install the 2AC9932-S. Remember to connect the

2AC9932-M with the 2AC9932-S in parallel as illustrated.

24V wires are supplied with the units.

• Connect both units with the 24V wires to the low voltage block.

The following pages illustrate piping diagrams, typical installations and the parts

that we recommend for an optimum performance of your central vacuum system.

GENERAL INFORMATION

An air outlet leading outside must always be installed on a two-motor 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.

• If your walls are made of gypsum board, never install a wall inlet in the centre

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 piercing a hole through the pipe.

• 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.
