10 TopVent V Use 1 Use 1.1 ntended use The TopVent V unit is used to heat high spaces in recirculation mode. Proper use also includes observance of the installation, commissioning, operating, and maintenance conditions (operating instructions) specified by the manufacturer as well as the consideration of foreseeable abnormal behaviour and residual dangers. 1.2 User group TopVent V units may only be installed, operated and maintained by authorized and trained skilled personnel. The operating instructions are for nglish-speaking operating engineers and technicians as well as specialists in building, heating and air technology. 1.3 Operating Modes TopVent V units have the following operating modes: Recirculation mode at low fan speed Recirculation mode at high fan speed Standby Off The application limits specified in the Section 'Technical ata' must be complied with. Any other use or any additional use counts as being improper. The manufacturer shall not be responsible for any damages that may result thereby. The standard version of the units is not suitable for operation in explosion-prone areas, in wet rooms or in rooms with a high dust incidence. 1.4 Residual dangers espite all of the precautionary measures taken, there are residual dangers; these are potential, non-apparent dangers, such as: anger when working on the electrical system. When working on the TopVent unit, parts (e.g. tools) can be dropped. Malfunctions due to defective parts anger from hot water when working on the hot water supply. 8

11 TopVent V onstruction and operation 2 onstruction and operation The TopVent V unit is used to heat in recirculation mode; it was developed specially for use in high halls. The unit is installed under the ceiling. t takes in room air, heats it in the heating coil and blows it back into the room through the Air-njector. Thanks to its high performance and efficient air distribution the TopVent V covers a large area. Therefore, compared to other systems, fewer units are needed to achieve the required conditions. 3 unit sizes, 2-speed fans, various coil types and a series of accessories make it possible to provide a customized solution for any hall. Special coils (hot water, steam, electric heating coils) are also available. 2.1 Unit construction The TopVent V consists of the heating section (with fan and heating coil) and the automatically adjustable vortex air distributor. oth components are bolted together, but can be dismantled separately again. eating section Air-njector ig. 1: omponents of the TopVent V 2.2 Air distribution with the Air-njector The patented air distributor called the Air-njector is the core element. The discharge angle of the air is set using the adjustable vanes. t depends on the air flow rate ( fan speed), the mounting height and the temperature difference between the supply air and room air. The air is therefore blown vertically downwards, conically or horizontally into the room. This ensures that with each TopVent V unit a large area of the hall can be heated, the occupied area is draught-free, the temperature stratification in the room is reduced, thus saving energy.

47 TopVent NV onstruction and operation 2 onstruction and operation eating section The TopVent NV unit is used for low-cost recirculation heating in high halls. t is installed under the ceiling. t takes in room air, heats it in the heating coil and blows it back into the room through the outlet nozzle. The air distribution cannot be regulated with the TopVent NV. The unit is therefore especially suitable for applications in which the comfort requirement is comparably minor (e.g. high-bay warehouses). Thanks to its high performance the TopVent NV covers a large area. Therefore, compared to other systems, fewer units are needed to achieve the required conditions. 3 unit sizes, 2-speed fans, various coil types and a series of accessories make it possible to provide a customized solution for any hall. Special coils (hot water, steam, electric heating coils) are also available. The TopVent NV consists of the heating section (with fan and heating coil) and the outlet nozzle. oth components are bolted together, but can be dismantled separately again.

Any other or any additional use counts as improper. The manufacturer shall not be responsible for any damages that may result thereby. The units are not suitable for operation in explosionprone areas, in wet rooms or in rooms with a high dust incidence. 2 onstruction and operation The TopVent commercial AU unit is for the purpose of ventilating, heating and cooling in fresh air, mixed air or recirculation mode; it was developed specially for use in hypermarkets and supermarkets. The unit is installed by means of its corresponding roof frame in the roof. epending on the position of the dampers it draws in fresh air and/or indoor air, filters, heats or cools it and blows it into the room through the Air-njector. Thanks to its high performance and efficient air distribution the TopVent commercial AU covers a large area. Therefore, compared to other systems, fewer units are needed to achieve the required conditions. Thanks to its installation in the roof the units do not protrude so far into the room and maintenance work can be performed from the roof without disturbing operations. 2.1 Unit construction The TopVent commercial AU consists of the following components: resh air roof hood (with 2 weather grilles, inspection door, 2 filters class 4 and a differential pressure control device for filter monitoring) Mixed air box (with fresh air and recirculation air dampers linked to move in opposite directions and an actuator) Roof frame eating /cooling section (with fan, heat exchanger and integrated condensate separator for the condensate incurred) Automatically adjustable vortex air distributor Air-njector The roof hood and the heating /cooling section are insulated to avoid condensation on the external surfaces. The components are bolted together, but can be dismantled separately again. 1.4 Residual dangers espite all of the precautionary measures taken, there are residual dangers; these are potential, non-apparent dangers, such as: anger when working on the electrical system.

The discharge angle of the air is set using the adjustable vanes. t depends on the air flow rate ( fan speed), the mounting height and the temperature difference between the supply air and room air. The air is therefore blown vertically downwards, conically or horizontally into the room. This ensures that with each TopVent commercial AU unit a large area of the hall is heated, the occupied area is draught-free, the temperature stratification in the room is reduced, thus saving energy. 61

78 TopVent commercial UM Use 1 Use 1.1 ntended use The TopVent commercial UM unit is used to heat and cool large spaces in recirculation mode. Proper use also includes observance of the mounting, commissioning, operating, and servicing conditions (operating instructions) specified by the manufacturer as well as the consideration of foreseeable abnormal behaviour and residual dangers. 1.2 User group TopVent commercial UM units may only be installed, operated and maintained by authorized and trained skilled personnel. The operating instructions are for nglish-speaking operating engineers and technicians as well as specialists in building, heating and air technology. 1.3 Operating modes TopVent commercial UM units have the following operating modes: Recirculation mode at low fan speed Recirculation mode at high fan speed Standby Off The application limits specified in the Section 'Technical ata' must be complied with. Any other or any additional use counts as improper. The manufacturer shall not be responsible for any damages that may result thereby. 2 onstruction and operation The TopVent commercial UM unit is for the purpose of heating and cooling in recirculation mode; it was developed specially for use in hypermarkets and supermarkets. The unit is installed with its corresponding frame on the roof. t takes in indoor air, heats or cools it and blows it back into the room through the Air-njector. Thanks to its high performance and efficient air distribution the TopVent commercial UM covers a large area. Therefore, compared to other systems, fewer units are needed to achieve the required conditions. Thanks to its installation in the roof the units do not protrude so far into the room and maintenance work can be performed from the roof without disturbing operations. 2.1 Unit construction The TopVent commercial UM consists of the following components: Recirculation roof hood (with inspection door) Roof frame eating /cooling section (with fan, heat exchanger and integrated condensate separator for the condensate incurred) automatically adjustable vortex air distributor Air-njector The roof hood and the heating /cooling section are insulated to avoid condensation on the external surfaces. The components are bolted together, but can be dismantled separately again. The units are not suitable for operation in explosionprone areas, in wet rooms or in rooms with a high dust incidence. 1.4 Residual dangers espite all of the precautionary measures taken, there are residual dangers; these are potential, non-apparent dangers, such as: anger when working on the electrical system. When working on the TopVent unit, parts (e.g. tools) can be dropped. Malfunctions due to defective parts anger from hot water when working on the hot water supply.

Roof hood insulated, easy to remove with 4 handles Roof frame: made of sheet steel (insulation on site) an maintenance-free, low-noise sickle fan with a low energy consumption ondensate separator: with condensate connection Air-njector: patented, automatically adjustable vortex air distributor for draught-free air distribution over a large area ig. 2: onstruction of the TopVent commercial UM 2.2 Air distribution by means of the Air-njector The patented air distributor called the Air-njector is the core element. The discharge angle of the air is set using the adjustable vanes. t depends on the air flow rate ( fan speed), the mounting height and the temperature difference between the supply air and room air. The air is therefore blown vertically downwards, conically or horizontally into the room. This ensures that with each TopVent commercial UM unit a large area of the hall is heated, the occupied area is draught-free, the temperature stratification in the room is reduced, thus saving energy. 77

Proper use also includes observance of the installation, commissioning, operating, and maintenance conditions (operating instructions) specified by the manufacturer as well as the consideration of foreseeable abnormal behaviour and residual dangers. 1.2 User group TopVent M units may only be installed, operated and maintained by authorized and trained skilled personnel. The operating instructions are for nglish-speaking operating engineers and technicians as well as specialists in building, heating and air technology. 1.3 Operating Modes TopVent M units have the following operating modes: resh air, mixed air or recirculation mode with low fan speed ( % fresh air) resh air, mixed air or recirculation mode with high fan speed ( % fresh air) Standby Off The application limits specified in the Section 'Technical ata' must be complied with. Any other or any additional use counts as improper. The manufacturer shall not be responsible for any damages that may result thereby. 2 onstruction and operation The TopVent M unit is used to ventilate and heat in fresh air, mixed air or recirculation mode; it was developed specially for use in large spaces. The unit is installed under the ceiling and connected to a fresh air duct. epending on the position of the dampers it draws in fresh air and/or indoor air, heats it in the heating coil and blows it into the room through the Air-njector. Thanks to its high performance and efficient air distribution the TopVent M covers a large area. Therefore, compared to other systems, fewer units are needed to achieve the required conditions. 3 unit sizes, 2-speed fans, various coil types and a series of accessories make it possible to provide a customized solution for any hall. Special coils (hot water, steam, electric heating coils) are also available. 2.1 Unit construction The TopVent M consists of the following components: Mixed air box (with fresh air and recirculation air dampers linked to move in opposite directions) ilter box (with two bag filters class 4) eating section (with fan and heating coil) Automatically adjustable vortex air distributor Air-njector The components are bolted together, but can be dismantled separately again. The units are not suitable for operation in explosionprone areas, in wet rooms or in rooms with a high dust incidence. 1.4 Residual dangers espite all of the precautionary measures taken, there are residual dangers; these are potential, non-apparent dangers, such as: anger when working on the electrical system. When working on the TopVent unit, parts (e.g. tools) can be dropped. Malfunctions due to defective parts anger from hot water when working on the hot water supply.

123 TopVent MK ontrol systems 6 ontrol systems or the TopVent MK there are components for control of the room temperature and of the air distribution that have been specially developed by oval and optimally matched to the units. You will find a detailed description of these components in Section L 'ontrol Systems' of this handbook. 6.1 Room temperature control TempTronic R This is a programmable, electronic temperature controller for fully automatic operation. ts control algorithm with fuzzy logic ensures extremely small control deviations and minimizes energy consumption. The TempTronic R makes it possible to set a fixed fresh air rate. 6.2 ontrol of the air distribution Automatic control by the TempTronic R The TempTronic R also controls the air distribution in accordance with changing operating conditions (i.e. depending on the speed level and on the temperature difference between the supply air and room air). Manual control by means of a potentiometer n applications in which the operating conditions only seldom change or when not such high comfort requirements are made, the air distribution can be manually controlled by a potentiometer. ixed setting n cases where the air distribution always takes place under the same conditions (constant supply air temperature, constant air flow rate), it can have a fixed setting. 6.3 omplete system iginet (detailed description on request) TopVent M units are ideally controlled by the iginet system. This system, which was developed specially for oval indoor climate systems assumes all the control and regulation functions. t regulates the room temperature, controls the air distribution and constantly optimizes the proportion of fresh air (i.e. only as much fresh air is blown in as the room temperature permits without additional heating or cooling). 121

158 TopVent Options 9 Recirculation silencer The use of a recirculation silencer for noise reduction is recommended mainly if the TopVent units are installed under flat, hard ceilings (e.g. made of concrete or sheet steel). The recirculation silencer is mounted on the unit and thus reduces the sound reflection from the ceiling. The insertion attenuation is 3 d(a) compared with the total sound power of the relevant TopVent unit. Mount the recirculation units as usual via the 4 fastening points in the heating or heating/cooling section (for example by means of the optional suspension set). The air outlet box replaces the Air-njector. The total height of the unit is consequently reduced; the weight remains roughly the same. o not arrange any suspension points in the recirculation silencer! The silencer is not suitable for bearing the weight of the TopVent unit!

This can happen in cooling mode or when admixing fresh air. n addition the noise level is reduced (very slightly). The following components can be insulated: Air-njector Mixed air box ilter box The heating/cooling section in the TopVent unit is insulated as standard. 10 Air outlet box The external dimensions of the TopVent units are not altered by the insulation. The increase in pressure loss due to the narrowing of the cross section is negligible. When using TopVent units in lowceiling spaces, an outlet box can be mounted in place of the Air-njector. This reduces the minimum mounting height by 1 m compared to the standard design. The air outlet box has horizontal air discharge grilles on all sides. The vanes can be manually adjusted without tools to adapt the air discharge angle to the local conditions. 156
