Proper execution and sizing of air connections are essentialfor ensuring correct operation of the unit and an acceptablelevel of silence in the room.When designing and creating ducts, consider PRESSUREDROPS, FLOW RATE and AIR SPEED which need to becompatible with the characteristics of the unit. Specialconsideration needs to be made for pressure drops that aregreater than the unit's static pressure, which would lead toa reduction in flow rate resulting in unit shutdown.the weight of the ducts must not be supported by theconnection flangesAIR CONNECTIONSplace anti-vibration joints between the ducts and theunitthe connection to the flanges and between the varioussections of the ducts must ensure an airtight seal,preventing leakage in delivery and return which wouldcompromise overall system efficiency.limit pressure drops by optimizing the path, the typeand number of curves and the branchesuse curves with a wide radius. Consider whether itmight be useful to equip them with deflectors(especially if the air speed is high or if curves are tight)FEATURES FOR DUCTS FOR TREATED AIR1. The inner surface of the duct must be smooth andwashable. It must not contaminate the air.2. Thermally insulate the ducts and the flanges so as toprevent loss of energy and condensation build-up.Proper distribution of air in the room is essential forensuring comfort levels.In the selection and positioning of grilles, outlets anddiffusers, the following are to be avoided:3. excessive air speed4. formation of stagnant zones and layering5. entry of cold air into the room6. formation of localized currents (due to uneven airdistribution)7. excessive variations in ambient temperature in thevertical and horizontal planes8. short circuiting of delivery air towards return airFor purposes of comfort, the following things need to beconsidered:9. air diffusers must be selected by checking the soundpower generated at nominal flow rate conditions10. the disconnections to the diffusers are to be madeusing flexible elements11. the return grilles must be amply sizedM23740N6-03 01/10/07 page 12

Byacting on trimmer TR1 anticlockwise the control power of the motor and consequently the flow rate of the unit are reduced (1/4turn is equal to approximately -40 AC). By acting on the trimmer clockwise the flow rate at minimum speed can be increased.Check that the air flow rate is the unit nominal one (see general technical data).ATTENTION: by changing one of the 3 possible speed modes of the motor the other two are automatically altered. Wetherefore recommend checking that voltage and minimum speed do not fall below 110V AC. The air flow rate at minimumspeed must not be less than the one shown in the table.These operations must be performed when the unit has been permanently installed (with all the system accessories, filter,grilles, ducts, etc.) and with the aid of instruments suitable for the measurement of flow rate and voltage (anemometer andmultimeter).Size 21-25 31 41 51 71800 m 3 /h 1000 m 3 /h 1200 m 3 /h 1400 m 3 /h 2000 m 3 /hFlow rate222 L/sec 277 L/sec 333 L/sec 388 L/sec 555 L/secThe 3 speed board can be coupled to:HID-E1 3 SPEED SELECTORSelection of the 3 speed: MIN – MED – MAXSUMMER / WINTER manual changeM23740N6-03 01/10/07 page 14

ROUTINE MAINTENANCEBEFORE UNDERTAKING ANY SORT OF MAINTENANCE OR CLEANING, DISCONNECT THE ELECTRICAL POWERSUPPLY TO THE UNIT, AND ENSURE THAT OTHER PEOPLE CANNOT RE-CONNECT IT .All equipment is subjected to wear out.The maintenance makes :1. keeps the unit efficiency2. the components last longer3. keeps their efficiency and limits breakdownsTherefore, it is fundamental to perform periodical checks: afew controls can be performed by the user(AUTONOMOUS MAINTENANCE) and they are mainlycleaning activities; otherwise, controls have to beperformed by specialized technicians (INSPECTIONS).The machine should have a log book used to keep track ofthe performed controls. This will make fixing upbreakdowns easier.Take note of the date, type of control (autonomousmaintenance, inspection or fixing up), description of thecontrol, actions taken and so on.Parts subject to intervention:• AIR FILTERS• CONDENSATE DISCHARGE• ROOM AIR TREATMENT COIL• STRUCTURESERVICES• EXTERNAL FANS• DUCTING• FANS WITH BELT DRIVE• ELECTRIC ELEMENTSIt is very important for the air treatment coil to be able tooffer maximum thermal exchange. Therefore, the unit mustalways operate with the filters installed and clean.Cleaning and replacement of filters are very important interms of health and hygiene.Operation with clogged filters leads to a reduction in the airflow rate, resulting in malfunctions and unit shutdowns. Itmay even cause the unit to break down.AIR FILTERSHow often the filters need to be checked depends on thequality of outdoor air, unit operating hours, dust andnumber of persons in the rooms.As a guideline, cleaning should ideally take place betweenweekly and monthly. It is advisable to start with frequentchecks, and to adjust the frequency based on how muchdirt is discovered.PLEATED FILTERS1. Remove the closing doors2. Carefully extract the filter so that no dust reaches theparts below3. Wash the filtering mattress in warm water with acommon detergent.4. Carefully rinse it under water while preventing to pourwater in the room5. Dry the filter6. Reinsert it to its seat7. Reassemble the closing doorsOld filters, washing residuals and residual parts must bedisposed of, according to the law in force.CONDENSATE DISCHARGEDust and deposits could cause obstructions.Clean the tank, pour some water into the tank and check water flows normally.M23740N6-03 01/10/07 page 29

Check that theROOM AIR TREATMENT COILSTRUCTUREATTENTION: accidental contact with the fins of theexchanger may cause small cuts. When performing thefollowing steps, use protective gloves.The finned surfaces of the cooling coils and especially thecondensation collection trays are the places where microorganismsand moulds most easily flourish. It is thereforevery important to clean regularly with suitable detergentsand disinfect with appropriate products as necessary.panelling is fastened correctly. Poor fastening may giverise to malfunctions and abnormal noise and vibration.DUCTINGCheck the fixing screws and the operation of the anti-vibration devices in order to prevent the transmission of vibrations in theroom.ELECTRIC FANSMake sure that the fans and the relative protection grids are well fixed.Check, if possible, the unbalances of the electro-fan evident by noise and anomalous vibrations. Verify that the terminalprotection covers are closed and the cable holders are properly positioned.FANS WITH BELT DRIVEBELTThe tension of the belt can be adjusted by the worm screwon the slide connected to the electric motor, using a socketwrench or spanner.The belt is tensioned correctly when the tolerancesdefined in the enclosed sketch are respected.The tension of the belt should be checked after around 10hours of operation.L = distance between pulleysF = belt profile force SPA 2,8..3,6 KgD = elastic deviation = L x 0,0015PULLEYSAvoid the following situations:Avoid the following situations:1. Not sufficient tension, which causes slipping andoverheating and, as a consequence, the reduction ofservice life.2. Too much high tension, which subjects the belt to highstresses and, as a consequence, the reduction of unitlife and an excessive stress on bearings andsupports.3. Belt lifted from the groove4. Belt that reaches the bottom of the groove.5. Belts of different length (only in the case of coupledbelts).1. Pulleys not aligned.2. Pulleys not parallel.3. dirty pulleys; dust, grease, dirt deposited betweenthe surfaces of the belt and of the pulleys canmake the system operate in anomalousconditions.4. Pulleys not straight.5. Pulleys too small.6. Pulleys broken.7. Pulleys off-centre or unstable.8.

PERIODICAL VERIFICATIONS to be executed withthe frequency indicated by the Manufacturer (see theMAINTENANCE INSPECTIONS paragraph)PUT AT RESTIf a long period of inactivity is foreseen, for example thewinter for the cooling unit, the following is recommended:• to turn the power off in order to avoid electrical risks ordamages by lightning strike• to avoid the risk of frosts as shown in the HYDRAULICCONNECTIONS section, and, in particular- to empty or add glycole in the plant sectionssubjected to temperatures below zero- to empty or add glycole in the water heating coils,also in summer- to power antifreeze resistances if present.If the period of inactivity is particularly long or in the eventof extremely low temperatures, the external fans can beblocked temporarily; therefore, it is recommended toswitch them on every month in order to avoid seizures orelectrical overloads when the unit will be switched on.The restarting of the unit has to be carried out by qualifiedpersonnel, in particular, after the winter break for coolingunits or when seasonal switching should be performed.When restarting, refer to the SWITCHING ON section.Schedule technical assistance in advance to avoid hitchesand be able to use the installation when necessaryM23740N6-03 01/10/07 page 31

TROUBLESHOOTINGTHE OPERATIONS MUST BE CARRIED OUT BY TECHNICAL QUALIFIED PERSONNEL HAVING THE REQUISITESUNDER LAW REQUISITES AND IN CONFORMITY WITH THE SAFETY REGULATIONS IN FORCE.THE INTERVENTIONS WITHIN THE WARRANTY PERIOD WILL BE CARRIED OUT BY AUTHORIZED SERVICECENTERS.BEFORE RESETTING AN ALARM, IDENTIFY AND ELIMINATE ITS CAUSE.REPEATED RESETS MAY CAUSE SERIOUS DAMAGES.In certain machine configurations, some safeties may be placed in series and lead back to a single input on the electronicmodule.Therefore, check on the electrical diagram whether the device to which the alarm corresponds has other devices orsafeties connected in series.Below is a list of the possible causes of alarms.M23740N6-03 01/10/07 page 32

DECOMMISSIONING OF THE UNITDISCONNECTING THE UNITThe units must be disconnected by authorised personnel,who before proceeding must first read the Residual Riskssection in this manual.Before disconnecting the unit, the following must berecovered, if present:• the refrigerant (if the circuits cannot be isolated):the refrigerant must be removed using suctiondevices operating in a closed circuit, so as toensure that none of the compound is releasedinto the atmosphere.• the antifreeze in the circuits: when removing thisfluid, make sure that it does not leak and that it isnot released into the environment. The antifreezefluid must be stored in special containers.When recovering the substances present in the unit, allmeasures must be taken to avoid damaging persons andthings and polluting the surrounding area.Awaiting dismantling and disposal, the unit can also bestored outdoors, as bad weather and rapid changes intemperature will not cause damage to the environment, ifelectric, cooling and hydraulic circuits of the unit areintegral and closed.DISMANTLING AND DISPOSALTHE UNIT MUST ALWAYS BE SENT TO AUTHORISEDCENTRES FOR DISMANTLING AND DISPOSAL.When dismantling the unit, the fan, the motor and the coil,if operating, may be recovered by the specialist centres forreuse.All the materials must be recovered or disposed of incompliance with the corresponding national standards inforce.For further information on the decommissioning of the unit,contact the manufacturer.2002/96/CE DIRECTIVE REV.1 DEL29/01/07ATTENTION: This document contains important informationfor the disposal and/or recycling of the unit. Before installingthe unit, carefully read the use and maintenance manualincluded with it. Carefully conserve all of the documentationfor the entire life cycle of the unit.With the aim of protecting the environment, all of our unitsare produced in compliance with Direttiva 2002/96/EC onwaste electrical and electronic equipment (WEEE).The potential effects on the environment and on humanhealth due to the presence of hazardous substances areshown in the use and maintenance manual in the sectionon residual risks.Information in addition to that indicated below, if required,can be obtained from the manufacturer/distributor/importer,who are responsible for the collection/handling of wasteoriginating from equipment covered by 2002/96/EC. Thisinformation is also available from the retailer who sold thisappliance or from the local authorities who handle waste.The 2002/96/EC directive is applicable only in theEuropean Community and must always be complied withunless otherwise directed by the legislation of singlenations.In all member states, there are fines for fines for violation ofthe contents and requirements of this directive.If the equipment is sold outside the European Community,only local standards need to be complied with.Directive 2002/96/EC requires disposal and recycling ofelectrical and electronic equipment as described therein tobe handled through appropriate collection, in suitablecentres, separate from collection for the disposal of mixedurban waste.This type of separate management aims to reduce thewaste composed of electrical and electronic equipment byproviding for it during the design phase and by promotingre-use and recycling.The 2002/96/EC directive also includes as objectives thereduction in use of hazardous substances in electronic andelectrical equipment and the improvement of participation,as far as the environment is concerned, of individualsinvolved in the life cycle of said equipment.To distinguish the units that are covered bythe 2002/96/EC directive, they are marked bya symbol which indicatesseparate collection.This symbol shows a waste bin on wheelswith a bar through it (as shown in attachment4 of the directive).The user must not dispose of the unit at the end of its lifecycle as urban waste. It must instead be handed over toappropriate collection centres as set forth by currentstandards or as instructed by the distributor.If disposaltakes places at the same time as delivery of a newelectrical or electronic equipment for the same family, theproduct may be collected directly by the distributor..M23740N6-03 01/10/07 page 33
