


Fillingisdoneusingwaterandantifreeze.Therecommendedantifreezeispropylene
glycolthatisnon‐toxic.
Quantityofpropyleneglycolshalldependuponfrostconditions.

14

Fillingofthecollector(s)withwaterandantifreezeshallbedoneinthemorningorin
theafternoonduringsummermonths,inordertoavoidformingofairbubblesdue
tooverheating,thuscausingairtrapping,becausethenthesystemwouldnotbe
properlyventilatedanditispossibletoretainwhichwouldreduceperformance.
Fillingupofthecollector(s)istobedonewithlowflow,toletliquidtocomeout
fromtheoppositecopperpipeforbetterventilation.
Thefillingwithantifreezeistobedoneaccordingtotheinstructionsofthe
antifreeze(seetable)i.e.accordingtotheexteriortemperature▫Cunderwhichthe
systemisfunctioning.

8.VENTILATION


Specialattentionisneededtoprovideadequateventilationforthecollector(s)sothe
systemrunswithoutproblems.
Letthehotwater‐liquidtoflowfromtheoppositesiteofthefilling.Donotfillthe
systemwhenthecollectorhasbeenexposedtosunformorethan15mininsummer
monthsandmorethan30mininothercases,becauseoverheatingwouldcausethe
formationofbubblesinthecollector’sloopresultinginmalfunctioning.


10.LIGHTNINGPROTECTION

Incasethecollector,isplacedonthehighestpartofthebuildingasusual,special
measuresforlightningprotectionshallbetakenaccordingtothepertinent
regulations.Onelightingrodshouldbeconsideredtoinstall.Ifthereisready–made



11.ANTIFREEZEPROTECTION

Dependingontheplaceofthecollector(s)installationtherearepotentialfreezing
conditionsthatcancausedamagetothecollectorandthepiping.
Thustheuseofpropyleneglycolasantifreezefortheprotectionofthecollector(s)
andpipingisobligatory.
Thefollowingtablegivesthenecessaryvolumeratioofantifreeze(water‐antifreeze

12.MAINTENANCEREQUIREMENTS

12.1General
Thecollector(s),asallotherdevices,needsbasicmaintenancetoensureconstant
andhighperformanceatalltimes.
Therearevariousactionsthatcanbedonebytheuser;otheractionsmustbecarried
outbythemanufacturer’slicensedservicecrew.
Forhighperformanceandlongservicelifeoftheentirewaterheating‐distribution
installation,maintenanceisrequiredandfortherestofinstallation(boiler,piping,
controlsystems).

12.2Regularmaintenancebytheuser
Itispreferredthattheusercheckstwiceperyeartheplacewherethecollector(s)is
placedandvisuallycontrolsthecollectorandtherestofthecomponents.
Morespecifically:
‐checktheleaksincollector’spipingandtheleaksincomponents
‐checkforanycondensationofthecollector
‐checktheinstallationofthecollectoronthemountingkitandthescrewsonthe
mountingkitinordertofindanyloosescrewsbecauseofthewindetc.
‐ifforanyreasonthereisaneedtofilltheclosedsystemofthecollectorwithwater,
youshouldalsoaddantifreezetoretaintheratioaccordingtotableNo.1
‐Observeanyprobablecrackingofthecollector’sglass
‐Observetheclarityoftheglass
‐Observetheconditionofthepipinginsulationconveyingwaterfromthecollectorto
theboiler

Cleaningofthecollector’sglass,whenrequired,isbestdonewithouttoomuchsun.
Itisrecommendedthataskilledauthorizedtechnicianvisitstheinstallationinall
othercases.
Incaseofglasscracking,theglassshouldbereplacedimmediatelybecausethereis
riskofcollectorcorrosion.

12.3Maintenancebyservicecreweverythreeyears
Itisrecommendedthatthefollowingcontrolsshalltakeplaceperiodicallyevery
threeyearsbyalicensedteam:
‐checkglass(cleaning,cracking,shadingofcollector)
‐checkcollector’ssupportonthemountingkit
‐checkwater‐tightnessofcollectors
‐checkinsulationofcollector
Itisrecommendedthatthelicensedteamfillinaprintedformquotingthefollowing:
‐worksdone
‐spareparts
‐possibledamages

13.TROUBLESHOOTING–PROBABLECAUSE–SOLUTIONS

Troubleshooting Probablecause Solutions
Wheninstalledthereisno
hotwater.
Thesolarwaterheater
reachestheoptimum
performancetwodays
aftertheinstallation.
Duringthesetwodays,it
isrecommendedtoavoid
hotwaterconsumption,
evenifthereissunshine.

Pleasewaituntilnextdays
noon(sunshineobligatory)
Eventhough,awholeday
haspassed,nosufficient
hotwater.
1)Thereisairtrappedin
thecollectorclosedcircuit

2)Thereisaleakagein
theclosedcircuit.
1)Ventilationneeded.


2)Checktheleakageand
fillclosedcircuitwith
water
Thoughbeforetherewas
hotwater,nowthereis
not.
1)Watermixturebetween


2)Valvesproblem

3)Theconsumptionofhot
waterisbiggerthanthe
appliance'scapacity.
Hugehotwater
consumptionduringthe
night.
1)Checkthevalvesand
setoffthesolarwater
heatervalves.
2)Callinstallatorsto
checkifthevalvesare
damaged.
Coldwatertabsgivehot

Valvesorhydraulic
problem.
Checkthehydraulic
installation.Ensurethat
thesupplyofhotwateris
notconnectedtoasupply
ofcoldwater.
Hotwaterexists,but
thereisasmallleakageon

Probablythereisa
