ducting and low voltage wiring are run together from
the power Unit to each valve location, in the most
direct line possible. the wiring can be looped or
terminated at each inlet valve
the amount of airflow that is achieved at the hose is
dependent on the efficiency of the layout of the pVC
ducting.
Keep the line as straight as possible and avoid using
tight 90° fittings (except at each inlet) and try to use
90° sweeps wherever possible.

It is recommended that you always use good quality
cable, and be careful to run and secure the cable in a
manner that will provide the best protection from future
damage. the cable is usually best run together with the
pVC ducting, and can usually be strapped to the ducting.
the cable will run from the motor to the first inlet valve
and then loops to the next inlet valve and so on. It is
recommended that the connections are made at the
inlet valves so they are accessible in the future, rather
that join the cable at pVC junctions that may be difficult
to access and to service in the future.
leave a certain amount of cable slack - too little can
be a problem with not enough cable to work with or not
enough for future rework of the connection but also too
much can be difficult to push back into the wall.
damaged or faulty cable, which is rare, can be
substituted by wireless switching devices if absolutely
necessary. ask your iCentral dealer about the VaC-292
Wireless Hose Kit.
