Description of operation
                                                       The slot diffuser provides various modes of room ventilation
                                                       by various set up of movable part of the slot.

                                                       Horizontal airflow under the ceiling through a slot
                                                       system, (Fig. 4.)
                                                       When the slots are set up in this way, the air is discharged
                                                       from the slots at higher discharge velocities horizontally
                                                       with the ceiling along the entire length of the slot in the left
                                                       hand or right-hand direction. Passing out of the slot, the
                                                       fresh air flows in the horizontal direction under the ceiling
                                                       and gradually settles down over the workplace, which is
                                                       located at the more distant side of the slot. During such
                                                       slow sinking, the air heats up and no air draught is
                                                       perceived. This applies to the cold airflow, where flow
                                                       discharge range is relatively large. This option can be used
                                                       if there are no obstacles on the ceiling such as suspension
                                                       lamps, protruding ceiling, etc.

                                                       Alternating horizontal airflow under the ceiling
                                                       through a slot system, (Fig. 5.)
                                                       The feature of independent turning of individual slots
                                                       enables to set flow discharge direction combinations, with
                                                       the air flowing alternately to the right and to the left. To
                                                       maintain the flow discharge ranges for cold air given in the
                                                       technical documentation, it is necessary to meet the
                                                       requirement of generating a continuous flow in the slot in
                                                       the minimum length of 300 mm. In our case, a combination
                                                       of at least three slots located one after the other is used to
                                                       direct the flow discharge. The alternating horizontal cold
                                                       airflow option is used if there are obstacles on the ceiling
                                                       such as lamps that need to be by-passed, etc.

                                                       tem, (Fig. 6)
                                                       In this case, the slots are set up for an alternating oblique
                                                       discharge of warm air, when it is necessary to transport the
                                                       incoming air to the work zone along the shortest possible
                                                       path. When the air exits the slot in this way, it is possible to
                                                       adjust the directing blades so as to direct the outgoing air
                                                       to flow alternately to the right and to the left, while the
                                                       minimum flow width should be approximately 200 mm,
                                                       which is a combination of at least two subsequent slots.
                                                       With regard to the height of the ceiling and flow discharge
                                                       ranges, the discharge velocities in the slot are lower than
                                                       in the previous models.

Manufacturing the slot diffussers


Based on the manner of utilization, the following types of slot diffusers are marketed:


The IMOS- SV slot diffuser is composed of a cover grille made of unalloyed structural steel with a quality design with the
RALxxxx colour surface finish. The slots located in the cover grille openings are made of the PVC material of white or black
color, resistant to temperatures up to 80°C. It is recommended to use the slot diffusers in combination with the regulat-
ing component or air chamber.


The IMOS-SV P slot diffuser consists of a cover grille, one side of which has been designed to allow for connection of the
central or the left part of the slot diffuser. Its design corresponds with the IMOS- SV slot diffuser. It is recommended to
use it only in combination with the air chamber. If used in combination with the regulation component, it is necessary to
discuss this kind of design with the manufacturer.


The IMOS-SV S slot diffuser is composed of a cover grille, one side of which has been designed to allow for connection
to the right or the left part of the slot diffuser. Its design corresponds with the IMOS- SV slot diffuser and its combination
options are the same as for the right IMOS- SV P slot diffuser.


The IMOS- SV L slot diffuser is composed of a cover grille, one side of which has been designed to allow for connection
to the central or the right part of the slot diffuser. Its design corresponds with the IMOS-SV slot diffuser and its combina-
tion options are the same as for the right IMOS- SV P slot diffuser.


The regulating component (R) consists of a housing and spigot piece made from a zinc-coated steel sheet joined
together by spot welds. The inner part of the housing is filled with directing blades, the rotational movement of which is
controlled by leverages and their position is stabilized by a brake system. Both mechanisms are made of PVC material
resistant to temperatures up to 80 °C. A sealing material and flexible elements are stuck along the circumference of the
extension piece in order to connect the regulating component to the slot diffuser. The regulating component in combina-
tion with the IMOS- SV provides a convenient way of direct connecting to the air-conditioning duct.


The air chamber - (K). The air chamber, connecting socket and regulating damper are made of zinc-coated steel sheet.
Pins of the regulating component are made of an aluminum material and damper bearings of PVC material with thermal
resistance as given above. The parts of the air chamber are joined together by spot welds. A sealing material is stuck along
the circumference of the narrowed part of the chamber and flexible elements are fastened there to connect the regulat-
ing component to the slot diffuser. The air chamber is used in combination with the SV, SV P, SV S and SV L. It is
recommended to fasten it directly to a plasterboard ceiling.

                                 VI. MOUNTING AND MAINTENANCE
The SV-R slot diffuser
is in most cases connected to an air-conditioning duct, as shown in Fig. 19. Mounting consists of




Fig. 17. How to mount and adjust the IMOS SV - R slot diffuser.
To mount the diffuser, insert the IMOS SV-R slot diffuser into the air-conditioning duct. First, cut out an opening with the
dimensions on both sides exceeding the dimensions of the regulating component by 5 mm.. Then fasten it to the air-con-
ditioning duct using the M3x15 studs. Next, insert the IMOS SV cover grille into the regulating component. To set up the
device, insert a screwdriver into the first slot on the right or left-hand side. The screwdriver opens or closes the directing
lamellas and so sets the required air discharge. After the required parameters are achieved, turn the screw with the screw-
driver to lock the adjusted position. To make further adjustments and to change direction of the flow, turn the slots in the
required direction.
                                                                 The IMOS SV-K slot diffuser is fixed to an inter-ceiling in
Slot diffuser IMOS SV - K                                        most cases. To mount the IMOS SV-R slot diffusers, insert
                                                                 the air chamber into the inter-ceiling space, which can be
                                                                 made for example from plasterboard plates, see Fig. 18.
                                                                 To attach the air chamber to the ceiling, use four threaded
                                                                 rods of the M8 size, or another suspension material. To
                                                                 adjust the required height with respect to the inter-ceiling,
                                                                 turn the threaded rod towards the stud. Then you need to
                                                                 slide the connecting flexible pipe to the connecting socket
                                                                 and interlock against accidental release, using a stud and
                                                                 secure it by a PVC tape, for example. The last step to do is
                                                                 to insert a cover grille into the regulating component. To set
                                                                 up the device, insert a screwdriver or a rod into the slot in
                                                                 the middle of the slot diffuser. By moving the screwdriver to
                                                                 the right or to the left, the air control blade can be opened
                                                                 or closed and the required air discharge adjusted. After the
                                                                 required parameters have been set, it is possible to fine-
