i. Instructions for unloading on the site as well as installation and connection i.1. Unloading on the site The air handling unit – AHU ‐ is delivered as one section or in several sections, which are to be assembled on site. The AHU is delivered on transport pallets, legs or on a base frame. Loading and unloading as well as transport on the site is possible by fork‐lift truck or by crane using suitable lifting straps. i.1.1 Unloading by fork‐lift truck. The forks of the truck must be sufficiently long to avoid any damage to the AHU underside. i.1.2 Unloading by crane AHU delivered on transport pallet must be lifted by straps as shown in the illustration. AHU delivered with legs must be lifted by straps secured to the legs as shown in the illustration. i.1.3 Transport of unit without base frame on the site Units without base frame are always delivered in sections with each section on a pallet. Sections can be transported on the site by hand manual forklifts. i.1.4 Lifting a unit with straps Use an appropriate lifting beam with a sufficient span to avoid that the straps touch and damage the drip nose profiles and the inspection side with handles, pipes and accessories – for example manometers, cabinets, tabs for measuring the pressure. 20 ...
i.1.5 Lifting a unit with preinstalled brackets on the base frame for lifting. Lifting beam and straps are not included in the delivery. i.1.6 Roof unit with bitumen roof Avoid damaging the drip nose profiles along the bitumen roof. Keep the protection profiles of Styrofoam on the unit until the installation has been completed. If the unit is lifted by straps, the straps must be kept away from the drip nose profiles by bars to avoid damage to roofing profiles. 21 ...
i.1.7 Roof unit with steel roof For units with steel plate roof, the steel plates are delivered uninstalled on a separate pallet. Do not step or walk on the plates. i.1.8 Pre‐assembly storage The AHU must be protected from the weather and accidental impact. Plastic packaging must be removed and the unit covered with tarpaulin or similar materials. In order to minimize condensation, sufficient air circulation must be ensured between the covering and the unit. i.1.9 Tilt less than 30˚ during transportation of the section with heat pump – DVU During transportation, the unit section ‐ DVU must always be in the upright position or tilted less than 30˚. If it is necessary to tilt the unit more than 30˚, the suction pipe of the compressor must point upwards to prevent the escape of oil from the compressor sump. i.2. Installation ‐ mechanical i.2.1 Free area in front of and above the unit Important! When positioning the unit on the site, it must be ensured that an area with the same width as the unit is kept free for service and inspection and also for replacement of fans and exchanger, if needed. The width of the free area must be at least 900 mm. Important! For safe access to the cabinet with electrical components, if the cabinet is placed on top of the unit, the free area from the upper edge of the cabinet to the ceiling must be at least 700 mm. i.2.2 Supporting surface The surface beneath the unit must be level, horizontal and vibration‐free. The surface must be able to withstand the load of the AHU. Weights of the sections are written in Annex 2. Remember! Duct work must be sound insulated and must not be mounted directly on beams, trusses or other critical building parts. i.2.3 Adjustable feet under legs or base frame and transport of sections Adjustable feet are provided in a carton box placed inside the unit. Adjustable feet are delivered for indoor units and not for outdoor units. Sections can be transported on the site by hand manual forklifts or similar. The frame profiles in the edges of the sections have carrying capacity for lifting by the hand manual forklifts. ...
i.2.4 Base frame assembly Base frame is delivered unassembled for the indoor units that are delivered in sections on pallets. Assembly of the base frame is illustrated on 4 pages in a manual in a plastic bag which is attached to one of the large base frame parts. The 4 pages with the illustration regarding the assembly of the base frame are also available in this user manual in annex 4 , 5, 6 or 7. There are two types of base frames: 1. 150 mm high base frames 2. 250 mm high base frames There are 4 different manuals and each of them illustrates the assembly of the 4 different types of base frames: 1. Manual about the 150 mm high base frames for AHUs in the sizes from DV 10 to DV 40. The name of this manual is – Base frame 150 DVZ 10 ‐ 40 2. Manual about the 150 mm high base frames for AHUs in the sizes from DV 50 to DV 150. The name of the manual is – Base frame 150 DVZ 50 ‐ 150 3. Manual about the 250 mm high base frames for AHUs in the sizes from DV 10 to DV 40. The name of the manual is – Base frame 250 DVZ 10 ‐ 40 4. Manual about the 250 mm high base frames for AHUs in the sizes from DV 50 to DV 150. The name of the manual is – Base frame 250 DVZ 50 – 150 Example of 250 mm high base frame for AHUs in the size from DV 10 ‐ 40 ...
i.2.5 Base frames for outdoor units Outdoor units must be installed on 250 mm high base frames and are always fitted to the AHU sections. Hot‐dip galvanized base frames are recommended for outdoor units. Systemair delivers these base frames without the above mentioned adjustable feet. i.2.6 Installation on the site of unit sections at the base frame when sections are delivered on pallets Lift up the section by hand manual forklifts to the level where the underside of the section is even with the overside of the base frame. 1. Pull the section to the correct position on the base frame by lifting straps – it is maybe necessary to support the section by heavy duty furniture trolleys (see the photos below) Example of heavy duty furniture trolley turned with the wheels upwards. Placed in this way on the forks of the hand manual forklifts the heavy duty furniture trolleys are suitable for safe and careful rolling of the unit sections over to the base frames. Example of very heavy duty furniture trolleys. Turned with the wheels upwards and placed on the forks of hand manual forklifts these heavy duty ...

2. Pull sections together with lifting straps. We recommend the below shown type of brackets because this type is not damaging the frame profiles of the units. An example of lifting strap is shown below. 3. Sections are mounted to base frames with long self‐drilling screws. The frame profile under the inspection doors is placed over the horizontal profile of the base frame. See the example on the photo below. 25 ...
i.2.7 Joining the AHU sections The sections must be placed on the base frame and if the unit is delivered with 100 mm legs, the sections must be positioned directly opposite each other. 1. Ensure that the internal factory‐fitted rubber sealing is undamaged 2. The sections are then to be positioned directly opposite each other. If the sections are built with legs, the adjustable feet can be used to get the sections parallel and at the same height. 3. Press the sections hard together so that the rubber profiles are so flat that the iron frames of the two sections are joined. Straps with tensioner as shown below are suitable for pressing the sections hard together. 4. The sections are then to be locked permanently together with the black plastic‐coated Systemair Disc‐Locks. The Disc‐Locks are delivered in a carton box placed inside the unit. Place each Disc‐Lock over the 2 factory fitted locking pins. The discs and locking pins are not reliable for pulling the sections together. They are only sufficient for keeping the sections well together, so just turn each disc gently with the supplied Allen key. Use a sequence where each disc is tightened with only one click at a time. If the unit is placed too close to a wall with no space left for the mounting of Systemair Disc‐Locks, brackets must be placed inside the unit to keep the sections permanently together (brackets for this purpose are not delivered by Systemair) i.2.8 Fitting the ductwork Flexible duct connections between AHU and ductwork must always be installed. Be sure that flexible duct connections are almost fully stretched. (Flexible connections are ordered as accessories and they are placed inside the unit). At the fan outlet on a centrifugal fan, the duct size should be as close to the outlet size as possible. Avoid blockage and turbulence at the fan outlet. i.2.9 Risk of stack effect by vertical ducts and wind pressure on louvers On special occasions stack effect – also called chimney effect – in the ducts create airflows that drives the ...
i.2.10 Remove transport brackets – when spring mounts are installed i.2.10.1 Impeller diameters 220 – 560 mm If the fans are installed on spring mounts the transport brackets must be removed after the installation of the air handling unit. Two transport brackets are fitted to the coil springs during transport and installation. Both transport brackets must all be removed to give the full anti‐vibration function to the coil springs. The transport brackets are made more visible with yellow labels. After removal of the transport brackets they must be disposed of safely. After disposal of the transport brackets the yellow label on the outside of the fan inspection door has no function and should be removed. 27 ...
i.2.10.2 Impeller diameters 630 – 1.000 mm If the fans are installed on spring mounts the transport brackets must be removed after the installation of the air handling unit. Four transport brackets are fitted to the coil springs during transport and installation. The four transport brackets must all be removed to give the full anti‐vibration function to the coil springs. The transport brackets are made more visible with yellow labels, as shown in the picture below. After removal of the transport brackets they must be disposed of safely. After disposal of the transport brackets the yellow label on the outside of the fan inspection door has no function and should be removed. 28 ...
i.2.11 Refitting of guards The guard is a safety guard installed inside the door. Tools are necessary for the removal of the guard. If the guard has been demounted during the installation on the site, the guard must be refitted before startup of the unit. Insert the edges of the guard in the frame profile in the groove that is in the frame profile, and connect both parts of the guard at the middle with 2 screws. Replace the vibration damping foam rubber list if it is damaged. i.3. Installation ‐ electrical i.3.1 Necessary overvoltage protection device, that leads lightning overvoltage to an earth lead on a safe way. The Installer and user must be aware of the fact that lightning strikes make a risk that requires installation of overvoltage protection devices to lead the lightning overvoltage to an earth lead in a safe way. Installer and user must take care of this according to local statutory requirements. i.4 Installation – Pipes for water – hot and chilled, valves and drains i.4.1 Description If ordered with the unit, the valves and valve motors are stored in a carton box placed inside the unit. Water trap(s) – standard or optional ‐ is (are) necessary to ensure escape of water from the tray under plate heat exchanger and (or) cooling coil. Water trap(s) is (are) stored in a carton box placed inside the unit. 29 ...
i.4.2 Pipe connections Connection pipes on heating‐ and cooling coils are provided with external thread. Drainage outlets on drip trays are provided with external thread. i.4.3 Possibility of extracting components from the unit Pipes and cables must not obstruct the inspection doors and components which can be extracted from the unit. Potential components for extraction are filters, fans and rotary heat exchanger. i.4.4 Pipe connections to batteries i.4.4.1 Heating coils Pipes for hot water must be protected by insulation against frost and loss of heat. Further protection against frost can be obtained by installing electrical heating wires around the pipes and under the insulation combined with temperature sensors and a control system. Pipes, insulation, electrical heating wires, control system for heating wires and circulation pump are not delivered by Systemair. i.4.4.2 Cooling coils If ordered with the unit, the valves and valve motors are stored in a carton box placed inside the unit. Pipes for cooling must be protected by insulation against condensation on the pipes and loss of cooling in the summer. Pipes and insulation are not delivered by Systemair. i.4.4.3 Rigid pipe mounting brackets for valves, circulation pumps and pipe system The coil and pipes from the coil are not constructed to withstand the weight and stress from valves, circulation pumps, long pipes and insulation of pipes. The system must be supported carefully in rigid pipe mounting brackets to roof, floor and walls. i.4.4.3.1 Pipe connection to heating coils The heating capacity of the coil with only 2 rows is independent of the connection of the hot water in equal flow or in counter flow to the direction of the air, but connection of the hot water to the pipe marked for inlet and the return water to the pipe marked for outlet is very important to ensure that the sensor for transmission of the water temperature really will be placed in a return circuit of the coil (Screw‐joint for the water temperature sensor is welded in the main collection pipe for return water). For the frost protection of heating coil, the water temperature in the coil is transmitted to the controller The controller always generates a signal to the valve motor that keeps a sufficient flow of hot water to protect the coil against frost. This frost protection is also activated when the running mode is “off”. Coils with 3 rows or more must always be connected in counter flow to the airflow. NOTE: If glycol is added, the glycol must be without additives and auto glycol must not be used.Automatic bleeding has to be installed at the highest point of the 2 pipes — supply or return pipe. If the heating battery is built with 3 or more rows, the water flow must be in counter flow to the direction of the air. ...
To protect against frost a temperature sensor for the transmission of an analog signal to the controller is placed in a pipe on the collection pipe for return water. The sensor must be fitted water tight with a cap in the pipe before water under pressure is in the battery. The pipe for the sensor is soldered on the collection pipe and it is important to hold contra on the pipe, when the cap is tightened. Battery seen from above. The sensor measures the water temperature of the water inside one of the small pipes for return water in the battery. The sensor reduces the area in this pipe and hereby also the flow of warm water in this pipe. The temperature in this pipe is reduced more than the temperature in all other pipes by the airflow through the battery. Because the lowest temperature in the battery probably is measured here, this system creates early and safe warning of frost. It is important that the cap is tightened sufficient to keep the sensor system fully water tight. i.4.4.3.2 Pipe connection to cooling coils for chilled water Coils with 3 rows or more must always be connected in counter flow to the airflow. NOTE: The glycol must be without additives and auto glycol must not be used. ...
i.4.5 Draining condensate water Drip trays for collection of condensate water are installed under plate heat exchanger and cooling coil. Each drip tray is provided with a drainage outlet. A water trap is always necessary. To avoid freeze ups and frost bursts of water trap and pipes, sufficient insulation is recommended and installation of heating between the insulation and water trap/pipes could even be necessary (insulation, heating and controller for the heating are not delivered by Systemair). i.4.6 Draining condensate water from plate heat exchanger Condensate from the plate heat exchanger is collected in the drip tray. Heavy negative air pressure in this section prevents the water from flowing out of the drainpipe. A water trap with sufficient closing level of the water is essential to ensure that condensate water flows out of the unit. The closing level of the water trap must be estimated correctly to ensure safe escape of the water (see the illustration and estimate the minimum closing level according to the table).The pipe diameter of the water trap and sewage system must be identical to the pipe diameter of the drainage outlet from the tray. A water trap is optional and installation of the water trap is not included. Remember to check that there is water in the water trap.

r.3. Filters – always replace filters with new filters with the same characteristics to maintain SFP value Filters in supply air and in extract air always have the same sizes of frames and the number of filters for supply air and extract air are always the same. REMEMBER to order filters for supply air as well as for extract air. To maintain the factory‐calculated SFP values for the air‐handling unit, it is very important that filters with the same characteristics for start pressure as well as lifetime replace factory‐mounted filters. To achieve the most favourable SFP values, the factory‐mounted filters represent the lowest achievable start pressure as well as the longest achievable lifetime. If other filters with higher start pressure and shorter lifetime replace the factory‐mounted filters, the user will experience smaller airflow and/or consumption of more electricity, and the SFPv value calculated by Systemair according to the Eurovent certification will not be achieved. Poor SFPv values will be detected by tests according to commissioning standards, DGNB, LEED or BREEAM sustainability standards and locally defined performance standards (the SFPv is with new clean filters). Filter frame for bag filters must be of NON‐PVC plastic to ensure safe disposal by incineration. For each individual air handling unit you will find the data for the factory‐mounted filters in Annex 2 that is always provided in a cover placed inside the air handling unit when the air handling unit is delivered to the final site. Annex 2 is also always available from Systemair if you can inform us of the production number of the air handling unit. The production number is always printed on the so‐called machine card that is attached to the unit. You will find an example of this machine card in section d.2.1 of this manual. The factory‐mounted filters comply with indoor air quality demands of customers and with the SFP values according to local legislation.

s. Instructions designed to enable adjustment and maintenance to be carried out safely, including the protective measures that should be taken during these operations s.1. Protective measures and additional protective measures Adjustment and maintenance must be done by skilled technicians – usually based on service contracts for some years or long‐term ESCO contracts. The units are provided with guards to avoid unintended hazards and injury because of rotating parts in the unit. The potential sources of harm are the fans with fast rotating impellers. Hazards from the impellers are obvious during operation, but when power is cut‐off, the impellers are still potential hazards due to after‐run for at least 20 seconds. Notice that even cut‐off the impellers are still potential hazards. The fan guard’s are the inspection doors and the doors are provided with locks. Inside the doors are additional protection installed – guards that only can be removed by use of tools. Other motor‐driven parts are dampers with damper motors and rotary heat exchangers, but the movement is so slow that guard measures are not necessary. Just keep your hands away from places with risk of injury. Use particulate respirator when filters are replaced. s.1.1 Necessary protection measures prior to start‐up. Ensure that all protection measures are installed correct before start‐up. s.1.1.1 Design of protection measures Inside the doors are additional protection installed – guards that only can be removed by use of tools. s.1.1.2 Configuration of frequency converters with installed guard A frequency converter is mounted beside the fan in some units. If the configuration of frequency is carried out with the fan in operation, the guard must be installed for safety reasons and a long cable must be installed between the frequency converter inside the unit and the control panel outside the unit. s.1.2 Safe adjustment and maintenance Before maintenance and repair, the unit must be switched off by switching off the automatic circuit breakers and block them by padlocks.. See the illustration below about how to place a padlock on each automatic circuit breaker. Note that lamps must be switched on during maintenance (lamps are an accessory – only installed, if ordered). Use cut‐resistant gloves for protection against injury from sharp metal plate edges.

Installation of steel roof in the sizes 10‐150 8.1 Overview Mount rails A1, B2, C3, D4, E5 on the unit for support of trapezoidal roof plates (mount also rails Y and Z on units of the size 30 and on units that are larger than size 30 longitudinally at the centre‐ line of the units). Place foam bands – P – on the horizontal rails A1, B2, C3 and D4 for support of roof plates. Calculate overhang of the roof at both ends of the unit and mount roof overhang profile – G1 on the first trapezoidal roof plate – F1 before the roof plate is mounted. Place and mount roof plates F1, F2, F3 and so on. Remember foam bands on the side laps between roof plates to prevent rainwater from passing through. Place roof overhang profile – G5 at the other end of the unit before the last roof plate is mounted. Mount sides and corners on the roof. Apply sealing where plates are joined to ensure water resistance ‐ even in stormy weather. 8.1.1 Mount rails. Units of size 10, 15, 20, and 25 Squeeze sealant in sufficient quantity between the underside of the rails A1, B2, C3, D4, E5 and the horizontal top side of the unit before the rails are mounted. This means that the rails are standing on 8—1 ...
sealant to achieve the tightest connection between rails and unit to prevent rainwater from passing under the rails and into the unit. Mount the rails A1 and B2 on the front side (the side with the inspection doors) – use the simple self‐drilling screws without the sealing washer – see the illustration of the screw below. Note: Rail B2 fits into the rail A1, and this offers the advantage that the rail B2 can be slid inside the rail A1 to adjust the length of rail B2 accurately to the length of the unit. In this way it is not necessary to spend time and effort cutting the rail B2. Mount the lower rails C3 and D4 on the back side of the unit. Note: Rail D4 fits into the rail C3, and this offers the advantage that the rail D4 can be slid inside the rail C3 to adjust the length of rail D4 accurately to the length of the unit. In this way it is not necessary to spend time and effort on cutting the rail D4. Mount vertical rail – E5 ‐ with the roof slope at each end of the unit It is important to place a screw in each hole – even though the number of holes for screws seems to be very large, a screw in each hole is necessary as the stress on the roof during stormy weather is extremely high. 8.1.2 Mount rails. Units of size 30 and units larger than size 30. On units of size 30 and on units that are larger than size 30, rails A1, B2, C3, D4, E5 must be mounted on the unit for support of trapezoidal roof plates, but also rails Y and Z must be mounted longitudinally at the centre‐line of the units to hold the trapezoidal roof plates. Squeeze sealant in sufficient quantity between the underside of the rails A1, B2, C3, D4, E5 and the horizontal top side of the unit before the rails are mounted. This means that the rails are standing on sealant to achieve the tightest connection between rails and unit to prevent rainwater from passing under the rails and into the unit. Mount the rails A1 and B2 on the front side (the side with the inspection doors) – use the simple self drilling screws without the sealing washer – see the illustration of the screw below. 8—2 ...
Note: Rail B2 fits into the rail A1, and this offers the advantage that the rail B2 can be slid inside the rail A1 to adjust the length of rail B2 accurately to the length of the unit. In this way it is not necessary to spend time and effort cutting the rail B2. Mount the lower rails C3 and D4 on the back side of the unit. Note: Rail D4 fits into the rail C3, and this offers the advantage that the rail D4 can be slid inside the rail C3 to adjust the length of rail D4 accurately to the length of the unit. In this way it is not necessary to spend time and effort cutting the rail D4. Mount vertical rail – E5 ‐ with the roof slope at each end of the unit. Mount the rails Y and Z on the unit with the centre‐line of the rails exactly over the centre‐line of the unit. It is longitudinal on the middle of the units to hold the trapezoidal roof plates. Notice, that rail Z fits over the lower rail Y, and this offers the advantage that the rail Z can be slided on the rail Y to adjust the length of rail Z accurately to the length of the unit. In this way it is not necessary to spent time and effort on cutting the rail Z. It is important to place a screw in each hole – even though the number of holes for screws seems to be very large, a screw in each hole is necessary as the stress on the roof during stormy weather is extremely high. 8.1.3 Roof overhang along the long sides of the unit The roof plates are longer than the width of the unit to ensure sufficient overhang along the sides of the unit. The overhang is 100 mm along each side of the smallest unit – size 10. The overhang is 150 mm along each side of the units – size 15, 20, 25. The overhang is 175 mm along each side of the biggest units – including size 30. 8.1.4 Calculation of the overhang at the ends of the unit. Mount overhang profile – G1. The roof must be between 200 and 400 mm longer than the length of the unit to secure a roof overhang between 100 mm and 200 mm at the each of the 2 ends of the unit, and the length of this overhang must be calculated before the first roof plate is mounted. 8—3 ...

The unit is delivered with 2 similar overhang profiles ‐ G1 and G5 ‐ one for each end of the roof. Mount one of the 2 roof overhang profiles – G on a trapezoidal roof plate. Use the self drilling, painted screws with sealing washers ‐ W ‐ see the illustration. Note: Foam bands ‐ P – are necessary between the overhang profile G1 and the roof plate F1. See the illustration. Self‐drilling, painted screws supplied with sealing washer for the mounting of the trapezoidal plate to the roof overhang profile. The total cover width of the trapezoidal roof plates always changes with the pitch of 205 mm between the trapezoidal ribs, making up a total length of the complete roof of ‐ for example 2100 mm, 2305 mm, 2510 mm and so on. We call this length of the total roof for RL and we call the total length of the complete unit for AL. The trapezoidal roof must always be longer than the unit, to obtain a reasonable overhang called – XX ‐ of the roof at both ends. In the table below you will find 40 different lengths of roofs (always changing with the 205 mm) and the lengths of units that are ideal for each of the 40 alternative roof lengths. Measure the total length – AL of the unit – for example 5000 mm between the 4982 and 5182 mm mentioned in the table below. 8—4 ...
8.1.5 Foam bands between rails and roof plates – mount roof plates. Place foam bands P between profiles A1, B2, C3, D4 and roof plates. The trapezoidal roof plates are mounted with the self‐drilling, painted screws supplied with sealing washer. 8.1.6 Foam bands between roof plates Mount the self‐adhesive foam band – O ‐ on the underlapping rib for water resistant and effective sealing due to the small slope of the roof. 8.1.7 Mount roof plates – some of them are overlapping by 2 ribs The width of each plate is always 1025 mm and some of the plates have to overlap by 2 ribs to achieve the optimal total length of the whole roof — see the illustration above. 8.1.8 Mount overhang profile – G5 on the other end of the unit. When the last trapezoidal plate (in this example F5) has been placed on the unit, the second roof overhang profile G5 must be pushed under the trapezoidal roof plate and mounted with the self‐drilling, painted screw with sealing washer. Mounting must be similar to the mounting of roof overhang profile under the trapezoidal roof plate at the other end of the unit. 8—6 ...
8.1.9 Mount side profiles and corners along the edges of the roof to protect persons Profiles N and O with the rectangular holes are for the long and lower side of the roof because rain can escape through the holes. Mount the profiles type N first and the profile O last because the profile O goes over the profile N. Mounted in this order, the profile O can match the end of the roof and the surplus length of the profile O will just cover part of the previous profile N. Mount the profiles L and M along the long and higher front side of the roof. Mount the 4 protection corners. 8.1.10 Apply sealing on plate joints to ensure water resistance. Finish installation of the steel roof by sealing all plate joints with silicone to prevent rainwater from passing into the unit. See examples below of joints to be sealed. 8—7 ...
