8.6 Instructions for Woodco systems installation

Pipe network
Pipe lengths, allowed between the different components of the vacuum unit, are indicative and pro­visional.
To do Woodco systems it is necessary to use strong and long-lasting installation material, available
in antistatic zync-coated pipes Ø 50 mm, or PVC installation material.
All connections must be watertight, in order to grant the maximum performance .
It is better to realize the pipe network in a straight line, because with many direction changes it is
necessary to realize a shorter pipe network.
Avoid networks with positive or negative traps.
For some connections it is possible to use spiral pipe, in antistatic plastic material, with smooth
internal walls. Radius of curvature for installation made with fl exible hose cannot be under 30 cm.
It is better to reduce to the minimum sections realized in fl exible hose, to optimize installation per-
formances. All pipes must be fi xed to walls or strong supports every 150 cm. Horizontal sections

must be made with spirit level, while vertical sections cannot be over 3,5 meters.

In case of connection between rigid steel pipes and fl exible pipes, the spiral inside the fl exible hose
must be connected to the steel pipe, to grant antistatic properties.
To avoid electrostatic charges, pipe network must be grounded, in accordance with current rules.

Warning
We recommend using only original pipes, connections and accessories as they have been realized
on this purpose.
Before installing and using Woodco system, we recommend to read this manual carefully and, in
case of doubts, please contact qualifi ed person.

Construction and installation of systems must be made according to safety rules related
to the place they are installed in.

WARNING: the system installation must be

made by qualifi ed personnel only.

9.1 Electrical connection

Before connecting the system to the electrical power supply check that the supply voltage correspon­ds to the required by the vacuum cleaner (see the identifi cation plate).

The manufacturer declines any responsibility for damages to persons and/or objects due to a con­nection to a non-complying electric wiring.
Follow the instructions (see picture page 22) detailed below to carry out the operation:

• Connect the input signal cable (MICRO LINE) to the Woodco Control Panel Micro Out (see ma-

nual)

• Insert the plug of the power supply cable from the central system in the electric inlet.

• Check that the electrical wiring of the house has been set up in compliance with the electrical

regulations in force.

• Do not power the system with supply voltage from provisional or temporary switchboards (for

example construction sites switchboards) to avoid possible damage to the electronic parts.

11.3 Dust collection, transfer and disposal

Where a separated refuse collection policy is in place, once removed from the vacuum cleaner,
the dust collected in dust bins and dust bags must be placed in the green “dry, non-recyclable
waste” bins.

11.4 fi lter cartridge maintenance

The fi lter cartridge can be restored as follows:

1A) blowing its surface with compressed air

1B) vacuuming its dirty surface with the vacuum unit, with a clean fi lter previously installed. In

this case, we recommend to shake the dirty fi lter, before vacuuming, to eliminate most of the
dusts that deposit between the folds.

N.B. Check the fi lter surface is not cut. If
this is the case, the fi lter cartridge should
not be used again and should be defi ni-
tely replaced.

ATTENTION
ALWAYS VERIFY THAT THE FILTER CARTRIDGE HAS BEEN CLOSED
CORRECTLY, A WRONG ASSEMBLY COULD DAMAGE THE PRODUCT.
DO NOT USE THE VACUUM CLEANER WITHOUT THE FILTER CAR­TRIDGE. ENSURE YOU HAVE REPLACED A SPARE FILTER CARTRID­GE BEFORE CARRYING OUT THIS OPERATION.

1C) washing it under fl owing water. Also in this case we recommend

to shake the fi lter before washing it in order to eliminate most of
the dusts that deposit between its folds.

ATTENTION: before replacing the fi lter cartridge back in the

system after washing, ensure it has completely dried. DO
NOT reassemble the fi lter if the surface is still wet or damp.

13 - SOUND EMISSION

A sound level measurement has been gauged by measuring the acoustic pressure and the sound
level of the vacuum cleaner. The test report is held at the producer headquarters.

14 - IDEAL LOCATION OF THE VACUUM CLEANER TO REDUCE SOUND

EMISSION

The following suggestions and measures will help reducing the sound emissions of the vacuum
cleaner:

• Fix the system to a solid wall (not to a cavity wall), preferably made of solid bricks.

• Avoid fi xing the system to an internal dividing wall, it is better to fi x it to an external perimeter
wall.

• You can also use sound-absorbing materials on the two side walls if these are very close to
each other; this will interrupt the sound wave and avoid resonance phenomena between the
two waves which could refl ect on the two opposite walls.

• You could possibly also soundproof the ceiling.

15 - VIBRATIONS

There is no contact between the hand, arm or body of the operator and the machine when vacuum
cleaning using the fl exible hose; for this reason there is no risk related to vibrations.
