4.1 HEALTHANDSAFETYOFWORKERS

TheEuropeanCommunityhasadoptedanumberofdirectivesonworkplace’shealthandsafety,whichinclude89/391/CEE,

89/686/CEE,2009/104/CE,86/188/CEEand77/576/CEEdirectives.Everyemployershallimplementsuchprovisionsandensure

thatworkersrespectthem:



Donottamperwithorreplacepartsoftheequipmentwithoutthespecificconsentofthemanufacturer.The

manufacturershallhavenoresponsibilitywhatsoeverincaseofunauthorisedoperations.



Usingcomponents,expendablematerialsorsparepartsthatdonotcorrespondtothoserecommendedbythe

manufacturerand/orlistedinthismanualmaybedangerousfortheoperatorsand/ordamagetheequipment

Theoperator’sworkplacehastobekeptclean,tidyandfreefromobjectsthatmaypreventfreemovements.

Appropriatelightingoftheworkplaceshallbeprovidedsoastoallowtheoperatortocarryouttherequired

operationssafely.Poorortoostronglightingcancauserisks.

Ensurethatworkplacesarealwaysadequatelyventilatedandthataspiratorsareworking,ingoodconditionandin

compliancewiththerequirementsofthelawsinforce.

TheunitoperateswithR410Arefrigerantgas,whichisagreenhousegasaccordingtotheF‐gasRegulation(EU)517/2014

(mandatoryintheEuropeanarea).ThisRegulation,amongtheprovisions,requiresalloperatorsinterveningingreenhousegas

systemstobeinpossessionofacertificateissuedorrecognizedbythecompetentauthority,attestingtoasuccessfulcompletion

ofanexaminationentitlingthemtocarryoutsuchwork.Inparticular:

Devicecontains3kgormorethan3kgofthetotalamountofrefrigerantgas:CategoryIcertificate.

TherefrigerantR410Aingaseousformisheavierthanairandtendstoconcentratehighlyinlittleventilatedenvironmentswhena

leakoccurs.Itsinhalationcancausedizziness,suffocationandcandeveloplethalgasifitbecomesincontactwithopenflamesor

hotobjects,(pleaseseeparagraph4.4“REFRIGERANTSAFETYDATASHEET”).

WearappropriatePersonalProtectiveEquipment(PPE)specifically,glovesandgoggles

Ensurethattheworkplaceiswellventilated.Donotworkinclosedroomsorditcheswithweakaircirculation.

Donotworkontherefrigerantnearopenflamesornearhotparts.

Avoidanyrefrigerantleakageintotheenvironmentandpayparticularattentiontoleakagefrompipesand/or

fittingsafterevacuatingtherefrigerantcircuit.

4.2 PERSONALPROTECTIONEQUIPMENT

Whenoperatingandmaintaining,the“i‐SHWAKV4”units,pleaseadoptthefollowingpersonalprotectiveequipment.



Protectiveclothing:Maintenancemenandoperatorshavetowearprotectiveclothingthatcomplieswiththebasic

operationefficiencyoftherefrigeratingcomponentsandoftheentiresystem.

6.1 FRAME

The“i‐SHWAKV4”unitsareallmadeofhot‐galvanisedthicksheetmetal,paintedwithpolyurethanepowderenamelsat180°Cto

ensurethebestresistanceagainstatmosphericagents.Theframeisself‐supportingwithremovablepanels.Allscrewsandrivets

foroutdoorinstallationsareingalvanizedstainlesssteel.Theindoorunitsalsohaveaself‐supportingstructuremadeofgalvanized

steelwithremovablepaintedpanels.

6.2 REFRIGERANTCIRCUIT

TherefrigerantcircuithasbeenmanufacturedbymeansofinternationalprimarybrandscomponentsandaccordingtotheUNIEN

13134ruleconcerningweldingprocedures.TherefrigerantgasusedintheseunitsisR410A.Therefrigerantcircuitincludes:4way

reversecyclevalve,electronicexpansionvalve,liquidseparator,liquidreceiver,valvesformaintenanceandcontrol,pressure

safetydevice(highpressureswitch),pressuretransducerstoaccuratelycontroltheevaporatingandcondensingpressures,filters

forthrottlingvalvetoavoiditsclogging,SAEvalvesforliquidandgasline.

6.3 COMPRESSORS

TheemployedDCinvertercompressorsaretwinrotaryhermetictype,designedespeciallytobeusedwithR410refrigerant.The

compressorsareallsuppliedwiththermaloverloadprotectionandaremountedonarubbermaterialactingasshockabsorbers.

Thecompressorsaremountedinaseparatechamberinordertobeseparatedfromtheairflowforreducingnoisesandarealso

suppliedwithcrankcaseheaterwhichoperatesinordertoavoidtheoildilutionwhichmaycauseseizureofthecompressor.The

crankcaseheaterstartswhenthecompressorremainsofffordurationnolessthan30minutesandwhenthedischarge

temperatureisunder20°C(withhysteresisof2.0°C).Whenthecompressorrestarts,thecrankcaseheaterwillstopoperation.We

recommendtoturnontheunitandtoputitinstandbymodeatleast6hoursbeforethefirststart‐up.

Theinspectionofthecompressorcanbemadethroughthefrontpaneloftheunitthatallowthemaintenanceofthecompressors

eveniftheunitisworking.

6.4 AIRSIDEEXCHANGERS

Theairsideexchangersaremadeupofcopperpipesandaluminiumfins.Thediameterofthecopperpipesis9.52mm,the

thicknessofthealuminiumfinsis0,1mm.Thepipesaremechanicallyexpandedintothealuminiumfinstoimprovetheheat

exchangefactor.Thegeometryofthesecondensersguaranteealowairsidepressuredropand,then,theuseoflowrotation
