5 2. rief esription of the Unit Casings of air handling units are made of galvanized steel sheets, whih are powder painted. Mineral wool is used for thermal insulation and sound attenuation. Unit over panels are 5 mm thik. The air handling units are intended for ventilation of medium-sized spaes (eg. single family houses, offies, et.), having operating ambient temperature and relative humidity. s standard, the unit is designed for indoor plaement. The operating temperature range for the unit is C C, outdoor air temperature. The air handling unit is not to be used to transport solid partiles, even not in areas where there is a risk of explosive gases. REGO is equipped with a rotary heat exhanger, RECU - with plate heat exhanger, whih may be replaed with summer assette, when reuperation is needless, air filters, an eletri or water heater, fans and automation ontrol system, to ensure safe and effiient operation of the unit. efore you open the door, the unit must be swithed off and the fans must have been given time to stop (up to 3 minutes). The unit ontains heating elements that must not be touhed when they are hot. To maintain a good indoor limate, omply with regulations and, to avoid ondensation damage, the unit must never be stopped apart from during servie/maintenane or in onnetion with an aident. If the unit is plaed in spaes with high humidity, ondensation might our on the surfae of the unit when outdoor temperatures are very low. Under onditions, when the outdoor air temperature is low and humidity is high, risk of heat exhanger frosting may appear. For this reason anti-frost protetion funtion is foreseen in the ontroller of the Komfovent air handling units. epending on the type of the reovery, different methods of anti-frost protetion are available: old air by-passing, or / and supply air fan speed reduing. For extremely low outdoor air temperature the dut mounted preheater is reommended. Counter ross flow heat exhanger is the mostly sensitive for low outside air temperatures, as the risk of frosting appears in the temperature range from 0 to -5 0 C and below. Standard aluminium ross-flow plate heat exhanger has better features, as the risk of freezing appears only at C. The lowest risk and the highest resistane to old outside air is a ompetitive feature of the rotary heat exhanger, as it is not freezing even at the temperatures of C if the humidity level of the air is appropriate. ir Handling Units Shemes REGO 00/500/700HE(HW)** - R* REGO 900/1200HE(HW) - R* REGO1600/2000/2500HE/HW - R* REGO 3000/000/500/7000HE/HW - R* U MLV we reserve the right to make hanges without prior notie. 5

10 EN The pipe work should be done in order to ensure the spae for maintenane and servie work. When arrying out the installation of heater pipes, make sure that hot water supply is ompletely disonneted. efore start-up of the air handling unit, the heater system should be filled in with water. Glyol is used in the air handling units with oil heat exhanger. Never pour glyol down a drain; ollet it in a reeptale and leave it at a reyling entre or the like. Glyol is highly dangerous to onsume and an ause fatal poisoning or damage the kidneys. Contat a dotor! void breathing glyol vapour in onfined spaes. If you get glyol in your eyes, fush them thoroughly with water (for about 5 minutes). *If water heater build in. When operating air handling unit in the temperatures lower than 0 C, it is neessary to use glyol additionally or assure the reversible heating agent temperature more than 25 C. It is important to maintain air heaters and oolers leanliness; that is to hange filters installed in the air handling unit on time. If the air heater or ooler gets dirty, to perform periodial leaning. utwork The air flows in/out air handling unit through dutwork. We reommend using galvanized steel (Zn 275 gr/m 2 ) dutwork, to ensure easy leaning and durability. It is neessary to use the dutwork system with low air flow rate and small pressure drop to have neessary air volume and low sound level and save the energy. The appropriate sound attenuators will redue the noise level of the fans in the premises. ll dutwork should be insulated with mm thikness insulation to avoid the ondensation. Note: temperature sensor 1 has to be mounted in the supply air dut under eletri heater (see the funtional diagram in Control System Eletrial Installation and Operation Manual). It is neessary to leave spae in straight air dut for sensor mounting and guarantee the spae for maintenane and servie work. Minimal spae between the unit and 1 sensor is the spae of double air dut diameter. utwork, steelwork and any other servies should not be supported off the unit. In dut system, for units with eletri air heater, use air losing damper without spring return mehanism. Final Inspetion fter installation of the unit, a thorough inspetion should be arried out. This should inlude inspeting the inside of the unit and removing debris and tools, whih may have been left behind by on site ontrators. Replae any panels, whih may have been removed and lose all aess doors, ensuring that the door sealing gaskets have not been damaged.. Maintenane It is reommended to arry out routine maintenane of the air handling unit REGO/RECU/OTK, 3 times per year. REGO 1200P use the key to open the door. o not release the door to swing freely, but open it slowly at a 90 degree angle. e areful while opening, beause logged filters might fall out. esides preventive maintenane inspetion, the following operations should be performed: 1. Rotary heat exhanger hek. Inspetion of the rotary heat exhanger is performed one per year. Free rotation of the rotary heat exhanger, ontinuity of the rotating belt, absene of damages of the rotor drums and the seal gasket are heked. It is neessary to hek the streth of belt. Free belt will slide and the effiieny of rotary heat exhanger will fall down. To reah maximal effiieny, rotor must turn at least 8 times per minute. Polluted heat exhanger will derease effiieny. Clean heat exhanger with an air blast or wash with tepid water. Chek out water falling on the eletri motor. 2. Plate heat exhanger hek. Inspetion and dedusting of the plate heat exhanger is performed one per year (it is removed from the unit and blown with an air blast or washed with tepid water). Note: plate heat exhanger may be replaed with summer assette, when reuperation is needless. 3. Fans hek (one per year). Polluted fans derease effiieny. efore performing any inspetion work, hek whether the unit is swithed off from the eletri power supply. 10 U MLV we reserve the right to make hanges without prior notie.
11 Fans should be arefully leaned with textile or soft brush. o not use water. o not break balane. Chek if diretion of fan turns is right, beause wrong diretion of turns gives only 30% rating. Chek if fan freely rotates and is not mehanially damaged, if impeller does not touh sution nozzles, fan does not spread noise, the pressure tubes are onneted to the nozzle (if it is required), mounting bolts are srewed. The rubber ouplings onneting the motor base and the unit should be visually inspeted for signs of wear and replaed as neessary. ny unusual noise or vibration when the fan is running should be immediately investigated, as this usually an indiation of wear or imbalane in the fan system.. ir heater hek. Reommended to perform periodial inspetion and leaning of heater. Chek the plates of water air heater. The air heater is leaned with hoover from supply air side or with air blast from exhaust air side. If it is very dirty, wash with tepid water, whih will not make orrosion of aluminium. Chek if position of return water temperature sensor is right. Chek if eletri air heater is properly fixed, wires onnetions are not damaged and heating elements are not bent. They an be damaged or bent due to uneven heat or uneven and turbulent air diretion. Chek if eletri air heater is lear of unneessary things and heating elements are not logged, beause this an ause unpleasant smell or in the worst ase dust an start burning. Heating elements an be leaned with hoover or wet textile. 5. ir damper hek (if it is required). Not fully opened outside air damper rises up the pressure in the system. Water air heater an freeze if outside air damper does not fully lose in not working air handling unit. Mounting and running of air damper should be heked and regulated. 6. ir filter logging hek. Change air filters when air filter logging is indiated. We reommend to hange filters at least twie per year: before and after heating season, or more*. Filters are one time used. We do not reommend leaning them. Stop the air handling unit before hanging filters. Pressure sensor Piture 7. Pressure sensor setting, whih indiates impurity of filters. Pressure sensor is set aording to EN 13779:2007 standard: 100 Pa for small systems, 150 Pa for big systems. Remove over from the pressure sensor and turn the ursor due to proper position. The indiator will turn on when filters will be logged. One of pressure sensors shown in Piture an be mounted in the air handling unit. Close the door after pressure sensor regulating proess. e sure that sensor does not indiate impurity of lear filters. Pressure sensors in the air handling units up to size 900 are regulated and set in fatory. * Clogged filters unbalane ventilation system, air handling unit uses more power.
