1. Usages The Allaway Manta central vacuum cleaning system is intended for professional usage in places where large areas need to be cleaned, with equipment that is used for longer periods than normal domestic use, and where the systems have several simultaneous users. Typical usages include hotels, offices, sheltered homes, passenger ships, daycare centres, and schools.
3.2. System for several users Two basic points are used as the basis for the planning: 1) The amount of air vacuumed simultaneously by two users does not fit to one Ø 44 mm dust pipe. 2) If larger pipes were used for the dust piping, the flow rate would be insufficient with only one user. If the spaces to be cleaned are divided into cleaning areas according to the requirements of the usage situations, this will guarantee a sufficient flow rate in the dust piping in all usage situations.
The most important issue when planning a system for several users is to lead a separate Ø 44 mm dust pipe from the cleaning area to the central unit. The pipes from the various cleaning areas must not under any circumstances be connected before the Ø 75 mm central unit collector pipe. In buildings with several floors, the Ø 75 mm collector pipe of the central unit can be led vertically through the floors, or the Ø 44 mm dust pipes from the cleaning areas can be joined on their respective floors.
4. Technical information for the central units The temperature of the motor or turbine may rise to almost 80SDgrC. The turbine is equipped with thermal protection at 80SDgrC, at which temperature the protection will turn off the device. Allaway Manta 3000 The Manta 3000 central unit is designed for one user with the maximum distance of 70 metres between a wall inlet and central unit.

6. Location of the central unit Several factors affect the location of the central unit. The following section discusses the situation for one central unit. The same principles can be applied for solutions with several central units, if the total area to be cleaned is divided into separate areas for each central unit. At least the following issues must be considered when planning the system: 6.1.
7. Dust piping 7.1. Features of the dust pipes The design of the dust piping is crucial for the operation of the entire system. The size and flow properties of the Allaway dust pipes are developed to ensure a flow rate in the piping of at least 20 m/s in normal use. However, this requires that the equipment-specific maximum line lengths and numbers of users are not exceeded. At a flow rate of 20 m/s, the dust and even any heavier rubbish will be transferred all the way to the dust canister.
Always connect the elbow coupling to a dust pipe without a sleeve. The sleeve can be cut from an intact dust pipe using a fine-toothed saw or a pipe cutter. Carefully remove any cutting burr using a sharp knife or file. Chamfer the outer edges of the cut pipe end. 8.2. Supporting Support the pipes with pipe clamps or metal clamps. Support the pipes to the framework of the wall, floor, and ceiling. Select the supporting distance according to the structures.
8.3. Hung ceiling ung ceilings are recommended for the installation of the piping, because it decreases the risk of damage to the pipes during installation. The installation can also be organised flexibly according to the other stages of the work, decreasing the cost of installation. 8.4. Cast floor If the building will have a cast floor but no hung ceilings, the piping can also be installed in the casting. Be particularly careful not to damage the piping during the casting work.
9. Chanelling the exhaust air It may be useful to perform the installation of the exhaust air duct together with the ventilation work. Use a spiral-weld tube or other metal pipe for the exhaust air duct that leads out from the central unit.
10.1. Installation frequency and height The locations of the wall inlets should allow the entire area to be cleaned using a standard length suction hose assembly (8 or 10 metres). Use a thread or a piece of electric wire proportioned to the scale of the design and the length of the suction hose for planning. The thread will help you to view the reach of the suction hose, and enable you to define the locations of the wall inlets.
10.4. Installing the wall inlet to a slab wall using a mounting plate The wall inlets are easiest installed on hollow walls with a wood or metal frame. Follow these instructions for installing the wall inlets on slab walls: 1. Select the installation height for the wall inlet. Use the mounting plate to draw the numbered holes on the wall. Cut a hole in the wall. Use holes 1-4 as the corners. Drill the holes 5-8. 3. Push the elbow coupling of the wall inlet to a dust pipe without sleeve.
10.5. Beam thickness in flush mounting When flush mounting a wall inlet, the minimum distance between the external surface of the wall inlet and the front surface of the rear wall slab is 80 mm. DUST PIPE WITHOUT A SLEEVE Ø 44 ELBOW COUPLING MOUNTING PLATE WALL INLET SCREW Ø 2.9 SCREW Ø 2.9, COUNTERSUNK THE LENGTH OF THE SCREW IS DEFINED BY THE THICKNESS OF THE WALL MATERIAL. If the beam thickness is less than 80 mm, use a frame RST for raised installation.
10.6. Installing a wall inlet on cast walls or floors When installing a wall inlet in casting, use a mounting bracket and a protective cover to ensure the correct level of the wall inlet and to avoid concrete from entering the dust piping during installation. 1. Install the elbow coupling, low voltage piping, and protective cover on the mounting bracket. Tie the protective cover to the mounting bracket using special thread.
10.8. Surface mounting of wall inlets In surface mounting, mount the wall inlets according to this picture. Consider the wall material in the installation. 10.9. Shortening the coupling muff for the wall inlet If necessary, shorten the coupling muff for the wall inlet to the SURFACE MOUNTING BRACKET correct length, or use an extension if the coupling muff does not reach the elbow coupling. 11.
Follow these instructions to start and turn off the central unit when using RST wall inlets: 1. Push the suction hose coupling muff to the wall inlet. 2. Turn the red start-up ring to ON. The central unit is started. Turn off the central unit by turning the start-up ring to OFF. 12. Connecting the central unit to the dust piping Lead a separate Ø 44 mm dust pipe from each cleaning area to the vicinity of the central unit. Connect the pipes to a vertical Ø 75 mm collector pipe using a single branch (5).
14. The Manta APC 3 central unit The Automatic Power Control (APC) for the central unit is intended for increasing the power of the central unit automatically when more than one user enters the network. The control unit recognises the change when several wall inlets are opened. The motor operating speed increases to ensure sufficient power for all users. Three wall inlets can be used simultaneously, if they are on separate lines.
