1. Read and strictly follow this installation and operating instructions to ensure
alonglifeandreliablecylinderoperation.
2. The cylinder’sinstallation and the initial start-up, as well as all electrical and
hydraulicworkmustbeperformedbyaqualiedprofessionalinstaller.
3. The device needs to be equipped with an additional safety valve (opening
pressure 0,6MPa) in order to protect it from the excess pressure.
4. Thecylindercanonlybeusedonconditionthatithasbeenproperlyinstalled
andthatitisintechnicallysoundcondition.
5. Priortorstcommissioningandaftereachstorage’semptyingitisnecessaryto
ventthecylinderinaccordancewiththepoint‘Start-up’.
6. Thetankisequippedwithamagnesiumanode-anadditionalprotectionagainst
corrosion.Theanodeisanoperatingpart,therefore,itisexposedtowear.The
condition of the magnesium anode should be controlled every 12 months,
however, it is due to be replaced with a new one every 18 months.
7. Donotusethecylinderifyoususpectthatthesafetyvalvemaybefaulty.
8. Appropriate precaution must be taken when using hot water. Temperature of
waterover40°Cmaycausehotfeelingandcanbedangerousforchildren.
9. Notethatwheninusecylinder’stting(tapandpipes)warmsup.
10. Cylindermustbeequippedwithsafetyvalve(includedintheinstallationset).
11. Ifsystem’spressureishigherthan0,6MP,pressurereducingvalvemustbetted
betweencoldwaterinletandsafetyvalve.
12. Ratedtemperatureofwaterinthecylindershouldnotexceed80°C.
Thecylinderissuitableforttinganimmersionheaterwiththermostate.g.GRW1.4,
GRW2.0.Theimmersionheatermustbettedinlieuofcork1½″.
Amaximumlengthofimmersionheater:360mm.

Connection to the central heating system
Cylindermustbettedtothecentralheatingsystembypipeunions1″.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).
ModelSN.Pisequippedwithaheatingcoilplacedintherightpartofthecylinder,
whereasmodelSN.Lintheleftpartofthecylinder.
Heatingcoilenablesco-operationwithe.g.centralheatingboilerorsolarcollectors.

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)andthedrainvalve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acut-offvalveonthecoldwaterinlet.
Hotwateroutletshouldbeledtotheconnection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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heatingmediumandsolarcollectorsvalves.Checkforwaterandheat-
ing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qualiedperson.
• Thewearconditionoftheanodemustbeinspectedannually.
• Theanodemustbereplacedonceevery18months.
- anoderodreplacement[2]:takeoffanode’sblank[1],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.
