Central vacuum systems

Basic planning information

Collect all the necessary data for the planning phase

•

Type of system (no of simultaneous operators in the whole building and on ever y floor)

•

Special requirements

- for the piping line

- for the position of the inlet valves

- for the position of the central vacuum cleaner

•

Voltage and power supply

•

Suction of liquids requested (yes/no)

•

Plan of the building (floor and section)

! WARNING !

The central vacuum systems Disan are planned to vacuum the domestic dust both in the domestic and professional sector.

Location of inlet valves on the plan

P L A N N I N G

•

Preferably point the compasses on the internal walls rather than on the perimeter ones in order to reduce the length of the tubes.

•

The convenience of the system is due to the limited number of inlet valves positioned in the right places. (We advise against installing one socket in each room).

•

Consider all the possible obstacles (such as walls, pieces of furniture etc.) which reduce the range of action of the hose.

•

Consider the difficulty of installing inlet valves on bearing walls or pillars.

Please notice:

•

We suggest to install a socket just at the bottom of the stairs to permit to clean it from the bottom to the top.

•

In the rooms which do not require frequent cleaning, such as the garage, the cellar etc., a 2 m flexible extension can be used (included in the

Deluxe kit of accessories) which extends the range of action to 9.5 m.

•

We suggest to install a socket in the garage and near balconies or floored entrances.

Planning the inlet valves

Using compasses, draw on the plan (preferably scale 1:100) circles with a radius of 7.5 m, as many as necessary to cover the surface (see example).

Please notice: 7,5 m corresponds to the standard range of action of the hose.

•

Avoid as much as possible large overlapping of the circumferences.

Planning of the tubing

Optimal suction depends on the tubing which should be as shor t and linear as possible. As a consequence, variations in the route should be avoided as much as possible.

•

If possible, the vertical descent should be at a central point of the house.

•

The tubing can be fitted under-track, inside the walls or on the false ceiling

•

When many simultaneous operators join together, install the reducer as in the drawing on page 6

Square inlet valves or rectangular are available and are compatible with the most popular brands on the market.

Location of the central vacuum cleaner

The central vacuum cleaner has to be located into the cellar, the storeroom, the garage or the hobbyroom, and in any case you have to guarantee a sufficient air-circulation for its cooling. Consider the acoustic and thermal emissions of the turbine motor.

•

The central vacuum cleaner should preferably be located at the lowest point of the tubing, in order to guarantee that even the heaviest vacuumed material is transported through the tubes to the central vacuum cleaner.

* the maximal simultaneousness of the floors can not be added

The horizontal pipe line on the floor requests a maximal diameter of 63 mm (2 operators working simultaneously). In the case it is necessary to vacuum on the same floor with more than

2 operators, split the pipe line on the floor into zones.

Central vacuum systems

•

In the big systems it’s advisable to have as many descents as the zones or the building floors and to connect them near the central unit. Install on every descent a sphere valve with manual closing.

This allows, in case of assistance on a line, the use of the rest of the system, helping any interventions.

Z 846

Z 848

In the 5,5 kW models besides the inspection cap install a by-pass valve.

The inspection cap makes easier an eventual assistance intervention.

The by-pass valve allows the cleaning of the piping. In this case the by-pass vale on the dust separator must be closed in order to allow the valve functioning on the line.

Ex. Of DS C03 100 modular range, for 3 operators working simultaneously (2 simultaneous operators on every floor)

In the case of a single descent the valve with manual closing is not necessary.

•

It is not advisable to install long horizontal lines of diameter 80 mm and 100 mm. If on these lines works a smaller number of simultaneous operators than that for which it was planned some clogging are possible.

In the cases in which the installation of these diameters is impossible to avoid, plan in the more distant point of the horizontal line a sweep TY in order to be connected to an inspection cap.

Ex. of installation of the inspection cap and the by-pass valve for modular models with 5,5 kW motors.

Planning of the water vacuum system

The water vacuum is possible thanks to its special accessory “wet pick-up” (code SZN348) to be dragged during the cleaning, or through an autonomous pipe line, which collects the water into a separator (code SZN361) placed near the central unit.

Central vacuum systems

•

Plan the inlet valves in the rooms where you intend to vacuum the water. Connect between them the inlet valves with a piping diameter 50 mm, to join to the pipe fittings equipped with the wet pick-up.

•

Plan a runner cap with a minimum diameter of

40 cm, to be placed in front of the separator, where the vacuumed water will be carried.

•

Connect the wet pick-up to the main pipe line of the system.

Please notice:

•

In the rooms where one intends to vacuum both dry and damp, install 2 separate inlet valves

•

The water vacuum system can be used only by a person at time

Characteristics of the fittings

In order to obtain maximum suction performances, the tubes have to be installed in an air-tight way.

Clutch fittings are not sufficiently tight in the long run and for this reason we advise against using them.

We strictly advice against:

• fittings with rubber gaskets or with O-rings

• spigot-and-socket joint fittings

• hot-welded fittings

Please notice: using the types of fittings listed above causes the following problems:

• depression reductions due to the progressive decrease in tightness of the rubber gaskets or

O-rings;

• clogging due to step-like obstacles or burrs inside the tubes;

• speed-reduction of the air-flow due to step-line obstacles or slight defects inside the tubes;

• whistles due to air-infiltrations inside the tubing caused by the progressive decrease in the tightness of the rubber gaskets or O-rings;

• whistles due to steps inside the tubes.

Use only 45 ° or 90° wide radius sweep.

“T” sweeps slow down the flow and cause clogging.

Z 166

NO

Use only 45 ° or 90° wide radius sweep ell.

Exception: there is only one 90

° (narrow radius) sweep ell: which is positioned behind the backup box.

Z 167

YES

NO

Please notice: planning the tubes so that the suction flow follows a horizontal or sloping route. Avoid long upwards suction flows.

Planning of the breather pipe

The central vacuum cleaners Disan have a correct air filtering, with environmental protection, and so the breather pipe is not strictly necessary. However, for hygienic reasons, we suggest to install it. The breather pipe shall have a larger diameter of the main line of the system.

Silencer

All the turbines used in the central vacuum systems

Disan are silenced with soundproofing materials at the end of the suction and of the delivery, in order to maintain a sound level lower than the levels previewed by the regulations.

The models DS Super Compact are equipped with an additional silencer, mounted on the internal part of the central unit.

Optional silencer are available in order to reduce the noisiness produced by the motors. The silencer must be mounted on the end of the breather pipe

(with whichever inclination), in order to allow the absorption of all the noises produced in the piping.

The zinc-coated silencer is available in the following models, to be chosen on the basis of the diameter used on the breather pipe.

• Zinc-coated silencer diam. 70/63 mm complete with 2 zinc-coated couplings

• Zinc-coated silencer diam. 100 mm complete with

2 zinc-coated couplings

Particular requirements of planning

In the case in which the piping crosses structures where there are dilatation joints or it connects 2 different structures use the following items:

• Dilatation joint in order to give flexibility to the piping

• Covering in thermal insulating material (normally used in the hydraulic field) to avoid condensate problems and to give flexibility to the piping in the case of settlings of the building or of the ground.

! WARNING !

Do not install external piping in contact with sunbeams and atmospheric agents. In these cases we advise to use zinc-coated stainless steel tubes.

Contact the technical office Disan.

If it is not possible to avoid the installation of external tubes, cover the tube with thermal insulating material

(normally used in the hydraulic field).

Central vacuum systems

Planning of the power mains

The power mains used for the control of the inlet sockets is 12 V (safety low-voltage) and permits to start the central vacuum cleaner through a contact on the sockets.

The covering supplied by Disan is fireproof according to IMQ standards; it has a 16 mm diameter, while the two internal cables have a 1 mm diameter.

The connections between the inlet valves are in parallel in the backup box with binding-screw.

Z 853

Systems up to 30 inlet valves

The connection is from inlet valve to inlet valve to the main electric junction box.

Systems with more than 30 inlet valves

We advise to split the system into zones or for floors, connecting them separately to the electric division box for 12V remote control wire. (code IE212) and to the main electric junction box. In this way it will be easier to find out any damage to the line (see drawing n the next page).

Use of the system with sequential starting device

This kind of system allows the sequential starting device of motors requested. It comes a real energy saving.

For the functioning of the sequential starting system, install inlet valves equipped with resistances (IS106) to be welded on the electrical cable at the output of the inlet valve. The connection of the line is always in parallel.

If the resistance is ordered with the inlet valve please add “R” at the end of the code of the valve.

Ex: SD310R. For the functioning of the sequential starting device system you need the special electronic control. For the functioning of the system it is necessary that both the resistances and the electronic control device are mounted.

Code IS02 device for models with 2 motors

(Mod. DS B02 and DS D02)

Code IS03 device for models with 3 motors

(Mod. DS C03 and DS F03)

Suggestions for extended systems

With the models DSA01 and DSB01 mount the resistances on the inlet valves and the electronic control device only when it is planned to extend the system.

With the models DSB02 and DSD02 we suggest to install at once the device for 3 motors.

CALCULATION OF THE MATERIALS/COST-ESTIMATE

Definition of the material needed for the tubing

The following table indicates the material needed approximately, based on the number of inlet valves established in the planning phase.

From these amounts the material about the diameters 63, 80 and 100 mm must be deducted which will be separately calculated on the plan.

Please notice: the calculation of the materials in the table is approximate. In case of special conditions in the distribution of the tubing (unusual routes) for instance if the central vacuum cleaner is positioned far away from the inlet sockets - please ask Disan’s technical office for advice.

Choice of the inlet valves and of the electricity plates

Choose the model of inlet valve based on the furniture. Please consider that the available inlet valves are similar to those of the most common brands of electric sockets (square or rectangular).

For systems for the industrial sector we advise the inlet valves with pin-jacks.

Please notice: for each type of inlet valve there is a backup box. Inlet valves and kits of cleaning accessories are interdependent.

See “Choice of the cleaning accessories” on page 16.

Choice of the central vacuum cleaner

Decisive factors in the choice of a central unit.

1. the number of operators working simultaneously

2. the pipe length.

If we consider that in normal condition every 1,000 m 2 of surface works 1 operator, the length of the tubes is lower than the vacuum power of the motors. In a building of 1,500 m 2 you need about

30 inlet valves and about 300 m of hose. Airlosses calculation are not requested if we consider this indication. If not so please contact the technical office Disan.

3. the quantity of dust that is vacuumed. In the buildings with many people (offices, banks, hotels, theatres, etc.) we advise dust container capacity in order to avoid many emptying.

Considerations about the number of operators working simultaneously needed

From the graph we can deduce that in normal conditions the attendants do not work simultaneously on the system.

If in a hotel work 6 attendants, on average the system is used by 4 operators at the most, while the other 2 persons do other works.

MAKING OF THE PIPING

General instructions

• The tubing should be installed together with or after the plumbing system in order to avoid changing of the route. The latter should be short and as much as possible.

• Unlike the plumbing system, the tubes of the suction system do not need any slopes.

• If obstacles are found, route and slope can be changed.

• The points of connection of the vertical column and of the breather pipe to the central vacuum cleaner are indicated in the paragraph “Location of the central vacuum cleaner”, on page 5.

Consider the air-flow

When you install the joints, follow the direction of the air-flow.

The joints installed and positioned in the opposite direction of the air-flow cause clogging and the slowing down of the flow itself.

Z 191

YES

NO

Laying of the tubing

The non-observance of the following instructions causes clogging, a reduction in the air flow speed and annoying whistling.

How to cut the pipes

Pipes must be cut using the pipe-cutter fitting this purpose (e.g. the Disan pipe-cutter code GE801 for diameters of 63 mm and pipe-cutter code GE803 for diameters up to 100 mm).

Then eliminate the slight defects inside the tube with a little knife or with glass-paper.

Cutting the tubes with the hacksaw causes irregular cuts and slight defects, which cause clogging.

Z 190 YES

Insert a secondary line into the main one

Laying and connection of the water vacuum system

• Insert tight the rubber couplings of the flexible tubes (connected to the water pick-up):

1. to the pipe fitting equipped to connect to the main line of the system.

2. to the pipe fittings equipped to connect to the line coming from the inlet valves for water suction

• Please pay attention that the water exhaust valve will be exactly positioned up to the runner cup in order to permit the perfect convey of the vacuumed liquids in the pipe.

Please notice: the rubber couplings could be inserted directly in the piping diameter 63 mm or with the reducers of the other diameters.

Z 857

Inlet valve for the water vacuum

Tubes and fittings are glued using a special adhesive

(cold gluing). The adhesive must be exclusively put on the “tongue” connectors/tubes.

If the adhesive is put on the “groove” connectors, this causes filaments inside the tube.

Please notice: when laying several fittings, we recommend - before gluing – to mark with a felt-tip pen the exact point (grading) where the fittings have to be connected. IMPORTANT! The adhesive reacts very quickly (approx. 20 seconds) after which it is impossible to move the glued fittings.

! WARNING !

Do not install external piping in contact with sunbeams and atmospheric agents. In these cases we advise to use zinc-coated stainless steel tubes.

Contact the technical office Disan.

If it is not possible to avoid the installation of external tubes, cover the tube with thermal insulating material

(normally used in the hydraulic field).

INSTALLATION OF THE BREATHER LINE

Installing the breather line towards the outside

Mount the silencer at the furthest point of the line in order to absorb as much noises as possible (see paragraph “Planning of the breather pipe” on page

8).

It is not advised to use too many sweep ells which could slow down the expulsion and consequently reduce the motor performances.

It is advised that the last meters (max. 5 m) of the breather line have a piping with a larger Ø in comparison with those of the pipes used for the vertical column. (see pages 8-9).

23

Central vacuum systems

LAYING OF THE ELECTRIC CONTROL LINE

The electric control line is installed in the following way: the electric cable coming out from the electrical junction box, which is placed near the central unit, is installed together with the tubing and is connected from one backup box to the other.

Fix the sheath to the tubes using the suitable wire clamps.

The backup boxes are connected by inserting the ends of the electric sheath pre-inserted into the two openings of the backup box.

Please notice: in order to allow future connection to the binding screw and to the inlet valve insert the electric cables for approx. 5 cm into the backup box and in the electric junction box.

TESTING

Testing occurs after completing the laying of the tubes and before laying the floor.

The purpose of the tests is in order to guarantee that the tubes are not damaged and that everything has been properly glued. Otherwise the system may not be air-tight.

This is very important because:

• even the smallest air infiltration into the tubing causes a reduction in depression values and airlosses;

• after the laying of the floors, it is very expensive to solve these problems.

Please notice: while laying the floors and plasters, be careful not to damage the pipe line.

1. Get the vacuum cleaner tester Disan (code GE815).

Disan’s testing kit includes the vacuum cleaner and all the fittings necessary for connection to the pipe line. If you use a traditional vacuum cleaner, ensure a perfect tightness using rubber couplings or similar devices.

Disan’s testing-kit is composed of:

1 powerful vacuum cleaner equipped with a premounted inlet valve.

1 vacuum gauge

1 stethoscope

3 PVC reducers 100-50 mm/80-50 mm/63-50 mm adapters

While the machine is working, read the depression value on the vacuum gauge.

Please notice: we suggest to measure the depression at every test, because it can change from site to site due to the different voltage.

Z 201

3. Insert the hose fitting into the end of the pipe line by using the most suitable fitting.

The end of the pipe line is the point where the central vacuum cleaner has to be connected.

Please notice:

• the vacuum cleaner must be connected to the pipe line so that there won’t be any possibility to have reduction of the depression value and airlosses.

• Disan’s vacuum cleaner tester is equipped with a thermostat which automatically switches off if the motor gets overheated. After cooling(8-10 minutes) the vacuum cleaner switches on again automatically.

Z 202

2. Measure the depression produced by the vacuum cleaner

Depression is measured by introducing the corresponding vacuum gauge (code GE800) into the end of the hose of the testing vacuum cleaner.

25

Central vacuum systems

4. Check the closing caps in the backup boxes

In order to carry out this part of the testing successfully, you need to make sure that all the 90° bends of the backup boxes are provided with the taps for the airtight closure of the system.

Z 203

6. Switch on the testing vacuum cleaner

Wait a few seconds so that the system creates the depression needed for the measurement. The vacuum gauge will indicate the exact depression value once the pointer has come to a standstill.

7. Measure the depression at the inlet valve

Check that the depression value measured at the inlet valve corresponds with that at the inlet of the testing vacuum cleaner. If the tubes and the fittings have been glued in a perfect way, the values will coincide.

Please notice: if the measured values do not correspond, there is an air infiltration in the tubing.

5. Insertion of the vacuum gauge

Insert the vacuum gauge directly into the inlet socket mounted on the vacuum cleaner.

Z 204

Location of losses

1. Locating the origin of the whistles

Follow systematically the pipe line and check if it is damaged. At the same time, listen if there are any whistles. If this check does not provide any successful result, use the stethoscope (part of

Disan’s testing kit) to listen systematically along the tubing for whistles; in particular where fittings and tubes have been glued. Even the minimum loss produces irritating noises!

2. Repair the tubing

If necessary, replace the tube or the fittings so that the tubing is perfectly tight.

Repeat the testing of the system.

After carrying out the test successfully, Disan suggests giving to the purchaser or to the chief of works a copy of the certificate (see second-last page of this handbook) and of the tubing distribution in order to avoid disputes or future liabilities.

On the systems with 2,2 kW motors the by-pass valve on the dust separator should be always closed.

•

The by-pass valve is used only on the systems with 5,5 kW motors, when on a motor just one operator is working. The excess of vacuum power is compensated by the by-pass valve Check that the valve is open and adjust eventually the bolt for a maximal efficiency.

Steps for the adjustment of the by-pass valve

1. with a wrench unscrew the bolt of the cover 1 and remove the metal cover and remove the soundproof cover 2.

3

4. remove one flexible hose from the inlet valve and check that the inlet valve starts working again

5. close the valve to the closing

6. reassemble the soundproof cover

By-pass valves adjustment

In the case that in the piping some by-pass valves will be installed for the self-cleaning of the lines, close the valve on the dust separator and adjust such valves as described in the paragraph “Check

of the functioning of the by-pass valve on the dust separator”.

Steps for the adjustment

1. After having removed the soundproof cover of the valve, start the system by inserting 2 flexible hoses into the inlet valves.

2. Adjust the valve as described in the paragraph:

“Check of the functioning of the by-pass valve on the dust separator”.

2. start the system by inserting the 2 flexible hoses into the inlet valves and vacuum by both of them.

3. adjust with a wrench the by-pass valve 3, by opening it until when an air infiltration could be heard

Testing of the inlet valves

Testing the inlet valves

•

Start the central vacuum cleaner up by inserting the vacuum gauge into whatever inlet valve of the system.

Z 214

•

Listen if there are any whistles due to losses of the inlet valves.

Whistles are due to:

1. an excessive screwing of the inlet valve into the backup boxes (see paragraph “Mounting and connection of the inlet valves”)

2. a damaged or incorrect mounting of the gasket.

Check if it is positioned correctly.

Z 215

After repairing, measure the depression again.

Final testing of the system

In this phase the installer tests the finished system.

Start the vacuum cleaner up by inserting the vacuum gauge into whatever inlet valve and measure the depression.

Please notice: if you use inlet valves with pin-jacks, the system can be started up creating a bridge with the two 12 V electric cables coming out of the central unit.

Wait a few seconds so that the system creates the depression necessary for the measurement. When the pointer has come to a standstill, read the exact value of depression.

Then check that the depression measured at the inlet valve corresponds with that measured at the inlet of the central vacuum cleaner.

These measures must correspond. Small differences in the value indicated in the “Technical data” sheet can derive from the voltage of the electric system and could be considered in the normal tolerance range. If the two values do not correspond, there is an air-infiltration in the tubing. Locate the origin of the loss by putting the stethoscope on the wall or on the floor along the tubing. An infiltration is present where you locate a whistle.

In case you notice whistles which aren’t caused by the inlet valves, locate the origin of those whistles by placing the stethoscope on the wall or on the floor along the tubing.

Practical testing of the functioning of the system

It is preferable that the customer himself cleans in order to check whether the suction system works perfectly.

ertification

The installing company

confirms the TESTING of the tubing in compliance with

Disan’s instructions.

Furthermore, it has been ascertained that:

1. no whistles are emitted by the tubing due to air-infiltrations

2. the depression measured at one inlet valve of the vacuum cleaning system corresponds with that measured at the testing vacuum cleaner.

Therefore any future damage is exclusively due to the intervention of a third party.
