Safety instructions
1. Readandstrictlyfollowthisinstallationandoperatinginstructionstoensurea
longlifeandreliablecylinderoperation.
2. Themanufacturerofthiscylinderwillnotbeliableforanydamagesduetothe
failuretofollowtheinstallationandoperationinstructions.
3. Thecylindermustnotbeinstalledinroomswherethetemperaturemaydrop
below0°C.
4. The cylinder installation and the initial start-up, as well as all electrical and
hydraulicworkmustbeperformedbyaqualiedprofessionalinstaller-instrict
accordancewithassemblyandoperatinginstructions.
5. Thecylinderisdesignedforstandingverticalinstallation-screwonthreefeet.

Connection to the central heating system
Cylindermustbettedtothecentralheatingsystem
bypipeunions3/4″.Acut-offvalvesmustbeinstalled
beforethepipeunions.Aowrateofheatingwatermust
behighenoughtomaximisecylinder’sefciency(see
technicaldatatable).Itconcernstheforcedcirculation
installation(withacentralheatingwaterpump).
Connection to the water system
Connectiontothewatersystemmustbeperformedaccordingtobindingnormsof
hydraulicinstallation.Thecylinderisapressureappliancedesignedforconnectionto
thewatersupplysystemwherethewaterpressuredoesn’texceed0,6MPa.Ifthewater
pressureexceeds0,6MPa,thepressurereducingvalvebeforecylindermustbetted.
Pleasefollowthewaterconnectioninstructionsbelow:
- installtheT-connectionwith6barsafetyvalve(e.g.ZB-4)tothettingofcold
water inlet [ZW]. It’s forbidden to install a cut-off valve (or any ow reducer)
betweentankandthesafetyvalveandonitsoutlet.Thesafetyvalvemustbe
installedinsuchaplaceastoquicklyletyounoticetheoutgoingwater,
- installthecylinderequippedwiththesafetyvalvetothewatersystem,
- installthecut-offvalveoncoldwatersupplypipe.
Hotwateroutletshouldbeledtotheconnection3/4″intheupperpartofthecylinder.
Every cylinder is equipped with connection 3/4″ intended for its installation to the
DHWcirculation.

Start-up
Beforethestart-upclosethedrainingconnectione.g.byscrewingthevalveinand
makesurethattheinstallationprocedureshavebeencarriedoutinaccordancewith
theregulationsincludedinthismanual.
Cylindermustbelledwithwater:
- turnonthevalveoncoldwatersupplypipe,
- turnonthehotwateroutletvalve(wateroutowwithouttheairbubblesindicates
thatthetankisfull),
- turnofftheoutletvalves.
Turnonthevalvesconnectingcylinderwiththecentralandthesolarcollectorheat-
ingsystem.Checkforwaterandheatingmediumleaks.Checkoutthesafetyvalve
performanceinaccordancewithvalvemanufacturer’sinstruction.
Operation
Followtheguidelinesbelowforsafetyandtrouble-freecylinderoperation:
• Checkoutthesafetyvalveperformanceonceevery14days.Donotusethe
cylinderifthewaterdoesnotcomeout(itindicatesthatthevalveisbroken).
• Cleaninsideofthecylinderperiodically.Thefrequencyofcleaningdependson
thedegreeofwaterhardness.Thecleaningshouldbedonebyaqualifiedperson.
• Thewearconditionoftheanodemustbeinspectedannually.
• Theanodemustbereplacedonceevery18months.
- anoderodreplacement[3]:takeoffanode’sblank[10],takeoutaninsulation
ring,turnoffthecut-offvalveoncoldwatersupplypipe,turnonthehotwater
valve(mixertap),turnthedrainvalveon,drainasmuchwaterasyouneed
toeasilyunscrewtheanoderod(avoidingroomooding).Removethecork
andunscrewtheanoderod.
• Heatupthewaterabove70°Cperiodicallyforhygienereasons.
• Failuresormalfunctionsnotifytotheseller.
• Insulatetheoutletpipeandheatingcoilconnectionpipestominimisetheheat
loss(recommended).
Aboveactivitiesarebeyondof the scope of warranty service (shouldbedoneby
theuser).

Cylinder emptying
Inordertoemptythecylinder:
• turnoffthevalveswhichconnectcylinderwithcentralheatingsystem,
• turnoffthevalveonthecoldwaterinlet,
• turnonthedrainvalve.
