Indications of operating status as well as indication of faults are visible in a display and on LEDs at a hand terminal.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
j. Installation and assembly instructions for reduction of noise and vibration emissions Due to the design and construction of the units the (A) weighed sound pressure level from fans and other components do not exceed 70 dB (A) outside the units. Data about sound in annex 2. Installation of the units on springs will reduce the transmission of noise and vibrations to the building. Systemair does not deliver springs for this purpose.
k.4.1.1 Checklist prior to start‐up Is the unit assembled correctly with its functions in the correct order? See annex 2. Are the sections and ducts assembled correct? See annex i. Check that fans and anti‐vibration mounts are not damaged after transportation and installation. Is the rotary exchanger turning freely? Are safety guards installed correctly? If the unit includes integrated heat pump(DVU), check whether it is installed and supervised by qualified service personnel.
k.5.5 Speed control of fans k.5.5.1 Frequency converters inside the unit are IP 20 Fan motor revolutions are controlled by frequency converters. Shielded cable must be used between the frequency converters and the motors. k.5.5.2 Frequency converters on the unit are IP 54 Fan motor revolutions are controlled by frequency converters. Shielded cable must be used between the frequency converters and the motors. k.5.
If a person is hit by a unit that is dropped, this could in unfortunate circumstances lead to irreversible injury or death. Claim for reduction of danger: Correct handling during transportation is described in this manual. If lifted by fork‐lift truck the forks of the truck must be sufficiently long. Safety measures are also described in this manual by use of crane. Information about weight of each section is also visible. l.2 Common for all unit sections l.2.
l.5.1 Risk caused by maintenance and cleaning of attenuators Hazards/dangerous area: High concentration of dust on the surface of the baffles might be harmful to the health. Dangerous incident: To breathe in particles that is harmful to the health. Claim for reduction of danger: Risk only exists during maintenance and cleaning. This takes place at least one time every year. Use of particulate respirator is described in this manual.
l.7.2. Risk caused by permanent magnet motor Hazards/dangerous area: Rotation of the shaft generates electricity. This danger is always visualized by a yellow warning label on the inspection door where permanent magnet motors are installed. Dangerous incident: Persons touching conductive parts get electric shock, burns, heart flicker and so on. Claim for reduction of danger: By installation or repairs of conductive components, the shaft must be blocked to prevent any rotation. l.7.
l.9 Heat pump units type DVU l.9.1 Risk of high temperature Hazards/dangerous area: Condenser batteries and pipes can achieve temperature of 60 degree Celsius. Dangerous incident: Vurderet ud fra ISO 13732‐1:2006, der er umiddelbart ikke risiko for forbrændinger. (berøringstid 2,5 sek). Claim for reduction of danger: No. l.9.2 Risk caused by lightning strike Hazards/dangerous area: Lightning strike close to the machine.
o. The conditions of stability during use, transportation, assembly, dismantling when out of service The unit must always be handled in an upright position. Never tilt any section more than 15 degrees. If sections must be tilted more than 15 degrees, sections with fans or rotating exchangers that can be drawn out for service must be secured carefully.
r. Adjustment and maintenance operations Must be performed by skilled technicians. In connection with demands for compensation, Systemair must have full and unhindered access to all relevant reporting on service, repair, modification and use since the unit was transferred from Systemair to a transport company at the Systemair factory. It is a condition for compensation that maintenance outlined on the following pages has as a minimum been performed. r.1 Shutdown of the unit to a safe state.
r.2 Recommended maintenance intervals Function Maintenance Unit casing Cleaning of the unit casing. Control of rubber seals on doors and between sections. Control of filters. Change the filters when maximum pressure is exceeded. To maintain the calculated SFPv values, filters with similar performance must replace the factory‐mounted filters. Start pressures of factory‐mounted filters appear from.
Function Maintenance Dampers Test the operation. Visual inspection of seals and tightness when closed. Check the dirt accumulation and clean, if needed. Coils may only be cleaned by gentle vacuum cleaning or by gentle blowing of compressed air. Coils may only be cleaned by high‐pressure water if it is one of the very few special batteries that are ordered and built for this. Bleeding, if needed. Test of frost protection sequence Test of cirkulation pump Check dirt accumulation and clean, if needed.
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.
r.3.1 Bag filters – the number of filters and the sizes of the frames Size of air handling unit Numbers of filters and sizes of frames (Width x Height) in mm.
r.3.
r.3.3 Bag filters Release the bag filter cells by activating the handles and pull out the filter cells of the unit casing. The frame profiles are to be cleaned and all seals checked for damage. The handles and locking guide rails are also to be checked to ensure that they can operate unobstructed. The new filter bags must be pushed carefully into the unit in order to ensure that they are sealed properly.
r. 4.2 Dampers Rubber seals between the damper blades themselves and between the damper blades and the frame are to be checked once a year. These seals are not to be lubricated or treated in any other way. Each damper blade is connected by a pivoting system. The steel rods and brass bushes do not require lubrication. The damper blades are fitted with synthetic bearings requiring no lubrication.
r. 4.3.2 Motor and belt drive The bearings are factory lubricated and do not require any service lubrication. The belt drive is to be checked for correct tightness and that it is undamaged. On smaller AHU, the rotor is fitted with an elastic belt drive and supplied with a reserve belt on the rotor. This belt drive does not require service and cannot be shortened. A new belt can be fitted using specialist tools. On larger heat exchangers the rotor has a V‐ belt with a belt connector.
r. 4.5 Run‐around heat exchanger DVR A heat recovery system of this type consists of a heating coil in the supply air‐ flow and a cooling coil in the exhaust air‐ flow. After an extended running period (normally a few years) dust particles can accumulate on the surface of the coils. This can reduce the efficiency of the coils. Cleaning must be carried out with the utmost care to ensure that the coil fins are not damaged.
r. 4.6.3 Electeric heating battery Check that the built‐in safety thermostat with an automatic reset function and the overheat thermostat with manual resetting are fully operational. r. 4.7 Plug fans DVE Dust can accumulate on the fan impeller which can cause imbalance and vibrations. The fan impeller must therefore be checked once a year and cleaned, if necessary. Anti‐vibration mounts and flexible connections should be checked at the same time.
r. 4.9 Outdoor air section DVY Dust and dirt can accumulate in this section. Large inspection doors give access for cleaning.
r. 4.10 Heat pump unit – DVU‐HP Mandatory annual control must be done by certified technicians from a certified company. See further description in annex 10 and 11.
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.
s.1.3 Personal protective equipment for maintenance staff – health and safety Use the below‐mentioned personal protective equipment for maintenance: Cut‐resistant gloves for protection against injury from sharp metal plate edges. Use CE‐marked gloves for this purpose. Helmet Particulate respirator – maintenance free including foam face‐seal and adjustable pre‐threaded headbands – for replacing filters. Padlock for locking the above mentioned automatic circuit breakers. Permanent magnet motor.

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.
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.
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.
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.

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.
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.
