k.6.7 Fire alarm function k.6.7.1 External fire signal that indicate block or run The unit is available without components for this function. The controller is as standard configured for ordinary running when the contact is closed (NC). By open contacts the fans stop and the dampers close. If disconnected, fire is indicated and the unit will stop until the signal is re‐connected. On the site qualified technicians are able to change the configuration. k.6.7.
k.6.9.2 Control of heating capacity connected to unit without Systemair control system Electrical heater installed with separate controller beside the heater. The separate controller is designed for capacity conversion of the 0‐10 V control signal from the main control system. The heating capacity is adapted in steps. The electric heater is not supplied from the air handling unit cabinet as the cabinet is not designed to supply the heater with power.
k.6.12 Temperature sensors Four sensors are always delivered with each unit. See below where the sensors are placed; 1 sensor in the extract air, installed inside the unit 1 sensor in the outdoor air, installed inside the unit before the supply air filter on the cold side of the heat exchanger 1 sensor in the supply air to be placed in the supply air duct by the installer 1 sensor in the exhaust, installed inside the unit k.6.
k.6.19 Free cooling A temperature sensor has been installed inside the unit in the outdoor air entrance. If the outdoor temperature after midnight is below the room temperature set point and the actual average room temperature is above the set point temperature, the fans start during the summer to cool down the building during night hours. k.6.20 Alarm signal By alarm there are 24 V DC on terminals in the cabinet. Lamps and cables are not available from Systemair. k.6.
l.2.1 Risk caused by surfaces, edges and corners Hazards/dangerous area: Sharp edges on plates might occur inside the machines as well as sharp edges on frames of dampers. No sharp edges on the outside of the units. Dangerous incident: Cut fingers/hands. Claim for reduction of danger: Risk only exists during maintenance and cleaning. This takes place at least once every year. Use of gloves and helmet is described in this manual.
l.6 Filters type DVG – DVF l.6.1 Risk caused by missing change of filters Hazards/dangerous area: Missing change of filters and missing maintenance decrease the capacity and final consequence will be breakdown. Dangerous incident: By extensive lack of of filter change and maintenance the machine can break down. Claim for reduction of danger: In the manual is the method and schedule for change of filters and maintenance specified. l.6.
l.7.3 Risk of rotating impeller caused by stack effect (chimney effect). Hazards/dangerous area: On special occasions stack effect – also called chimney effect – in the ducts create airflows that drives the impellers by turned off motors. Dangerous incident: Injury of fingers, hands and arms. Claim for reduction of danger: Eliminate this airflow for supply air and exhaust air by dampers with spring return motors for automatic closing of the dampers by turned off fan motors and by power failure. l.
Installer and user must be aware of the fact that lightning makes a risk that requires installation of overvoltage protection devices to lead the lightning overvoltage to an earth lead on a safe way. The need for overvoltage protection devices depend on where the unit is placed in and on the building. Installer and user must take care of this according to local statutory requirements. Overvoltage protection devices are also described in section i.3.3.2 of this manual m.
o.2 Transport of section with heat pump unit 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. o.
Check that the automatic circuit breaker marked F5 is still switched on because the lamps inside the unit, and only those lamps, are connected to this switch. Switch on the lamps for light during the maintenance activities. Use the start‐up procedure described in section k, when the maintenance activities are completed.
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.5 Other functions to maintain r.5.1 The unit The unit should be cleaned once a year when operating with normal air quality for comfort ventilation with no special hygiene requirements. To clean the unit, dry it off with a dry cloth, or use water mixed with a non‐corrosive cleaning medium. Any corrosion i.e. at the filters should be cleaned off immediately, and the surface treated.
r.5.3 Rotary heat exchanger DVC r.5.3.1 Rotor The rotor is to be checked at least once a year to ensure that it can turn freely and easily. This can be done by removing the belt drive at the motor and then turning the rotor manually with a hand on the peripheral rotor casing. At the same time the brush seals are to be checked for damage. The bearings are factory lubricated and do not require any service lubrication. During operation the rotor can become dirty.
If there is dust on the edges of the plates, remove it with a soft brush. If grease or other such substances are present, then the edges must be washed using grease dissolving detergents. r.5.4.1 By‐pass damper The damper blades are fitted with synthetic bearings requiring no lubrication. Each damper blade is connected by a pivoting system. The steel rods and brass bushes do not require lubrication.
r.5.6 Heating coil DVH, cooling coil DVK and change over coil DVHK After an extended running period (normally a few years) dust particles can accumulate on the surface of the coil. This can reduce the efficiency of the coil. Cleaning must be carried out with the utmost care to ensure that the coil fins are not damaged. The piping system must be vented once a year as air in the system can significantly reduce the capacity of the coil. r.5.6.
r.5.8 Silencer DVD During operation dust particles can accumulate on the surface of the baffles. Silencers that are designed for dry and wet cleaning are fitted with baffles that can be extracted from the unit casing. Large inspection doors give access to easily extraction of the baffles. Baffles designed for dry cleaning can be cleaned using a soft brush or they can be vacuum cleaned. Baffles designed for wet cleaning can be washed down using a soft brush and soapy water.
r.5.10 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.

Annex 8. 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.

To ensure that the lifting of the heat exchanger takes place in a safe manner, and to avoid personal injury and damage to the heat exchanger, we refer to the following instructions. The Hoval Enventus product warranty applies only if the following instructions are followed.
9.3.3 Installation During installation, make sure that the exchanger stands flat so that the rotor is not “at an angle” in the casing. CSD 290 mm 290 mm 9.3.4 Installation of radial walls Uncontrolled movement of radial walls may cause serious injury. Secure the radial walls carefully while working. Boards can be used to secure them.
9.3.5 Measurement. The hub with radial walls must be aligned both vertically and horizontally with the casing. If measurement indicates that there are discrepancies, the radial walls, and possibly also the hub, will need to be adjusted. Start measuring at the upper radial wall. Measure the distances A and B between the radial walls and the casing at points 1, 2, 3 and 4. Measure similar points on the next radial wall.
9.3.6 Installation of rotor segment and periphery plates. . Uncontrolled movement of radial walls and segments may cause serious injury. Secure the radial walls and segments carefully while working. Use a rope or strap with a pulley for controlled rotation.
Make sure that the upper and lower edges of the segment are located within the bent edges of the radial walls. Tap gently with a rubber mallet to ensure that the segment is in the right position. 9.3.7 Installation, first periphery plate Position the first periphery plate. The side with a hole must face up. See figure A. Insert a bolt in the hole at the top edge of the periphery plate. See figure A. Do not tighten. Insert a bolt in the groove at the lower edge of the periphery plate.
9.3.8 Installation of next segment Rotate the hub, radial walls and segment in order to facilitate the positioning of the next segment. Use a pulley with a rope or strap for controlled rotation.
9.3.9 Installation, next periphery plate. Position the second periphery plate. The side with a hole must face up. See figure A. Insert a bolt in the hole at the top edge of the periphery plate. See figure A. Do not tighten. The lower edge of the second periphery plate must overlap the first periphery plate and be secured using the bolt installed previously. See figure B. Tighten the bolt at the overlap. See figure B. A B Fasten the periphery plates together with a clamp bolt. Do not tighten.
9.3.10 Preparation of segments and periphery plates The periphery plates must be mounted together for preparation of segments and periphery plates. If a standard bolt is insufficient for bringing together the first and last periphery plates, a threaded rod can be used as described below. Position the threaded rod and nut. Tighten until an overlap is achieved. Tighten the bolt in the overlap. Replace the threaded rod with clamp bolts.

9.4 Installation of motor that turns rotor and sensor for rotation Installation of rotor motor and sensor for control of rotation in DVC module after assembly of divided rotor Fig.
Fig.2 Fig. 1, 2 and 6 By delivery of a DVC module with divided rotor, the motor is installed before delivery to the customer. Fig. 2 Fig.3 Fig.4 Fig.5 The drive belt must be placed around the rotor and the ideal distance is 9 cm from the 2 sides of the rotor. The rotors are always 20 cm thick. The distance to the drive belt from a side of the rotor must be between 9–11 cm. from the 2 sides of the rotor. Fig.6 Fig.
Fig.7 Fig. 7 and 8 Sensor for control of rotation must be installed by the installer. Distance must be 1‐4 mm between sensor and rotor. Check that the brackets which are used for the assembly of the rotor segments do not hit the sensor. Fig.8 1 ‐ 4mm Fig.9 Fig. 9 Pay attention to the heights of the brackets which are used for the assembly of the rotor segments. Please turn the rotor by hand in order to verify that the sensor will not be hit by the brackets.
