START-UP 66.6 REMOTE CONTROLSCheck that the remote controls (ON-OFF etc) areconnected and, if necessary, enabled with the respectiveparameters as indicated in the ELECTRICALCONNECTIONS section.Check that probes and optional components areconnected and enabled with the respective parameters(ELECTRICAL CONNECTIONS section and followingpages)6.7 EVAPORATOR WATER FLOW-RATECheck that the difference between the temperature ofexchanger return and supply water corresponds to poweraccording to this formula:unit cooling power (kW) x 860 = Dt (°C) x flow rate (L/h).The cooling power is shown in the table of the GENERALTECHNICAL DATA included in this manual, referred tospecific conditions, or in the tables on COOLINGPERFORMANCE in the TECHNICAL BULLETIN referred tovarious conditions of use.Check for water side exchanger pressure drops:Determine the water flow rate.Measure the difference in pressure between exchangerinput and output and compare it with the graph on WATERSIDE EXCHANGER PRESSURE DROPSThe measurement of pressure will be easier if pressuregauges are installed as indicated in the DIAGRAM OFSUGGESTED WATER CONNECTIONS .Absorptions of the different electric loads (compressors,fans, pumps etc)Temperatures and flows of the different fluids (water, air)both in input and in output from the unitTemperature and pressures on the characteristic points ofthe refrigerating circuit (compressor discharge, liquid,intake)The measurements must be kept and made available duringmaintenance interventions.6.10 CE 97/23 PED DIRECTIVE97/23 CE PED DIRECTIVE gives instructions for installers,users and maintenance technicians as well. Refer to localactuation norms :Briefly and as an example, see the following :COMPULSORY VERIFICATION OF THE FIRSTINSTALLATION:only for units assembled on the installer’sbuilding site (for ex. Condensing circuit + directexpansion unit)CERTIFICATION OF SETTING IN SERVICE:for all the unitsPERIODICAL VERIFICATIONS:to be executed with the frequency indicated bythe Manufacturer (see the MAINTENANCEINSPECTIONS paragraph6.11 OPERATING AT REDUCED LOAD6.8 CONDENSER WATER FLOW-RATECheck that the difference between the temperature ofexchanger return and supply water corresponds to poweraccording to this formula:unit cooling power + power absorbed by compressors (kW)x 860 = Dt (°C) x flow rate (L/h).The data is shown in the table of the GENERAL TECHNICALDATA included in this manual, referred to specific conditions,or in the tables on HEATING PERFORMANCE in theTECHNICAL BULLETIN referred to various conditions of use.Check for water side exchanger pressure drops:Determine the water flow rate.Measure the difference in pressure between exchangerinput and output and compare it with the graph onWATER SIDE EXCHANGER PRESSURE DROPS.The measurement of pressure will be easier if pressuregauges are installed as indicated in the DIAGRAM OFSUGGESTED WATER CONNECTIONS .The units are equipped with partialization steps and they can,therefore, operate with reduced loads.However a constant and long operation with reducedload with frequent stop and start-up of the compressor/s cancause serious damages for the lack of oil return.The above-described operating conditions must beconsidered OUT of standards.In the event of compressor break, due to the operating in theabove-mentioned conditions, the guarantee WILL NOT BEVALID and Clivet spa declines any responsibility.Check periodically the average operating times and thefrequency of the compressors starts: approximately theminimum thermal load should be such as to need theoperating of a compressor for at least ten minutes.If the average times are close to this limit, take the propercorrective actions.6.9 START-UP REPORTIdentifying the operating objective conditions is useful tocontrol the unit over time.With unit at steady state, i.e. in stable and close-to-workconditions, identify the following data :Total voltages and absorptions with unit at full load19

8MAINTENANCE8.1 GENERAL8.6 WATER EXCHANGERMaintenance must be done by authorized centres or byqualified personnelThe maintenance allows to:maintain the unit efficiencyreduce the deterioration speed to whom every equipmentis subject over timeassemble information and data to understand the state ofthe unit efficiency and avoid possible damages8.2 INSPECTIONS FREQUENCYThe inspections should be carried out at least every six monthsThe frequency, however, depends on the use.In the event of frequent use it is recommended to planinspections at close intervals:frequent use (continuous or very intermittent use, nearthe operating limits, etc)critical use (service necessary).8.3 UNIT BOOKLETIt’s advisable to create a unit booklet to take notes of the unitinterventions.In this way it will be easier to adequately note the variousinterventions and aid any troubleshooting.Report on the booklet:datatype of intervention effectedintervention descriptioncarried out measures etc.It is very important for the exchanger to be able to provide themaximum thermal exchange. Therefore, it is essential for theinner surfaces to be clean of dirt and incrustations.Periodically check the difference between the temperature ofthe supply water and the condensation temperature. If thedifference is greater than 8°C–10°C it is advisable to clean theexchanger .The cleaning must be effected :with circulation in the opposite direction respect the normalonewith speed at least 1,5 times higher than the nominal onewith a suitable product moderately acid (95% water +5% phosphoric acid)after washing, rinse with water to inhibit the residues ofdetergent8.7 CIRCULATING PUMPSCheck :no leaksbearing status (anomalies are marked by abnormal noisesand vibrations)The closing of the terminal cover blocks and the correctcable gland positioning8.4 PUT AT RESTIf a long period of inactivity is foreseen:Turn off the power in order to avoid electrical risks ordamages by lightning strikesavoid the risk of frost (empty or add glycol to the parts ofthe system exposed to temperatures below zero, maintainpowered any anti-freeze resistances )It’s recommended that the starting-up after the stoppingperiod is performed by a qualified technician, especially afterseasonal stops or seasonal switch.When restarting, refer to what is indicated in the START-UPsection.Schedule technical assistance in advance to avoid hitchesand to guarantee that the system can be used when required.8.5 WATER FILTERCheck that no impurities prevent the correct passage of water.34

RESIDUAL RISKS 11GeneralIn this section the most common situations are signalled. Asthese cannot be controlled by the manufacturer these couldbe a source of risk situations for people or things.Danger zoneThis is an area in which only an authorised operator maywork.The danger zone is the area inside the unit which isaccessible only with the deliberate removal of protections orparts thereof.HandlingThe handling operations, if implemented without all of theprotection necessary and without due caution, may cause thefall or the tipping of the unit with the consequent damage,even serious, to persons, things or the unit itself.Handle the unit following the instructions provided in the presentmanual regarding the packaging and in compliance withthe local regulations in force.Should the gas refrigerant leak please refer to the refrigerant"Safety sheet".InstallationAn incorrect installation of the unit could cause water leaks,condensate accumulation, leaking of the refrigerant, electricshock, bad functioning or damage to the unit itself.Check that the installation has been implemented by qualifiedtechnical personnel only and that the instructions contained inthe present manual and the local regulations in force havebeen adhered to.The installation of the unit in a place where even infrequentleaks of inflammable gas and the accumulation of this gas inthe area surrounding the area occur could cause explosionsor fires.Carefully check the positioning of the unit.The installation of the unit in a place unsuited to support itsweight and/or guarantee adequate anchorage may cause thefall or the tipping of the unit with the consequent damage tothings, people or the unit itself.Carefully check the positioning and the anchoring of the unit.Easy access to the unit by children, unauthorised persons oranimals may be the source of accidents, some serious.Install the unit in areas which are only accessible to authorisedperson and/or provide protection against intrusion intothe danger zone .General risksSmell of burning, smoke or other signals of serious anomaliesmay indicate a situation which could cause damage to people,things or the unit itself.Electrically isolate the unit (yellow-red isolator).Contact the authorised service centre to identify and resolvethe problem at the source of the anomaly.Accidental contact with exchange batteries, compressors, airdelivery tubes or other components may cause injuries and/orburns.Always wear suitable clothing including protective gloves towork inside the danger zone.Maintenance and repair operations carried out by nonqualifiedpersonnel may cause damage to persons, things orthe unit itself.Always contact the qualified assistance centre.Failing to close the unit panels or failure to check the correcttightening of all of the panelling fixing screws may cause damageto persons, things or the unit itself.Periodically check that all of the panels are correctly closedand fixed.If there is a fire the temperature of the refrigerant could reachvalues that increase the pressure to beyond the safety valvewith the consequent possible projection of the refrigerant itselfor explosion of the circuit parts that remain isolated by theclosure of the tap.Do not remain in the vicinity of the safety valve and neverleave the refrigerating system taps closed.Electric partsAn incomplete attachment line to the electric network or withincorrectly sized cables and/or unsuitable protective devicescan cause electric shocks, intoxication, damage to the unit orfires.Carry out all of the work on the electric system referring to theelectric layout and the present manual ensuring the use of asystem thereto dedicated.An incorrect fixing of the electric components cover mayfavour the entry of dust, water etc inside and mayconsequently can electric shocks, damage to the unit or fires.Always fix the unit cover properly.When the metallic mass of the unit is under voltage and is notcorrectly connected to the earthing system it may be assource of electric shock and electrocution.Always pay particular attention to the implementation of theearthing system connections.Contact with parts under voltage accessible inside the unitafter the removal of the guards can cause electric shocks,burns and electrocution.Open and padlock the general isolator prior to removing theguards and signal work in progress with the appropriateshield.Contact with parts that could be under voltage due to the startup of the unit may cause electric shocks, burns andelectrocution.When voltage is necessary for the circuit open the isolator onthe attachment line of the unit itself, padlock it and display theappropriate warning shield.Moving partsContact with the transmissions or with the fan aspiration cancause injuries.Prior to entering the inside of the unit open the isolatorsituated on the connection line of the unit itself, padlock anddisplay the suitable sign.Contact with the fans can cause injuries.Prior to removing the protective grill or the fans, open theisolator on the attachment line of the unit itself, padlock it anddisplay the appropriate warning sign.41

11RESIDUAL RISKSRefrigerantThe intervention of the safety valve and the consequentexpulsion of the gas refrigerant may cause injuries andintoxication. Always wear suitable clothing including protectivegloves and eyeglasses for operations inside the danger zone.Should the gas refrigerant leak please refer to the refrigerant"Safety sheet".Contact between open flames or heat sources with therefrigerant or the heating of the gas circuit under pressure(e.g. during welding operations) may cause explosions orfires.Do not place any heat source inside the danger zone.The maintenance or repair interventions which include weldingmust be carried out with the system off.Hydraulic partsDefects in tubing, the attachments or the cut-off parts maycause a leak or water projection with the consequentdamages to people, things or short-circuit the unit.42
