1 GENERAL SAFETY INSTRUCTIONS
To ensure safe use of the sauna, please read these safety instructions rst!

2 AURA HEATER
3 HEATER ASSEMBLY AND INSTALLATION
Heater assembly
1. Store the heater in its original package in an upright position and in a
warm and dry location until it is installed.
2. The package includes the heater, thermostat sensor, electronic
controllerandtherequiredcables.Inspecttheheatercomponents
visually. If you notice any discrepancies, please contact the store from
whichyoupurchasedtheheater.Donotexposeheaterpartstoblows
anddentingwhentakingitoutofthepackage.Thesauna’soorsurface
shouldalsobeproperlyprotectedbeforeyoubegintheinstallation.
3.Donotlifttheheaterbythejacket.
4.Anelectricianshouldconnectthewiresbeforetheheaterisinstalled.If
theheateristobeembeddedinthebenchstructure,itmustbelowered
throughthebenchesbeforemakingtheelectricalconnections.Ifneeded,
thepositionoftheheatercanbene-tunedbyusingtheadjustablelegs.
Observethesafetydistancesbetweentheheaterandanyinammable
materialinaccordancewiththetableonpage6.
5.Theheaterisinstalledsothatitleansagainstawallusingthebracket
provided(seethedimensionsonpage8).
6.Tofacilitateinstallation,adjusttheheater’sfeetsothattheyextendout
by8–9cm(atleastby5cm).Installtheheaterontheoorandadjustthe
feet so that the heater stands upright.
NOTE!Removeallplasticlmbeforeusingtheheater.

INSTALLATION AND OPERATING INSTRUCTIONS AURA 12/2022
Stacking the stones
Thesuitablestonesizeis5–10cmindiameter.
Use protective gloves.
• Only use stones with rough cutting surfaces,
intendedforsaunaheaters.Suitablestone
materialsincludeperidotite,olivinediabase,and
olivine.
• The use of ceramic “stones” and soft soapstone
objectsisforbidden.Itmaydamagetheheating
resistors.
• Rinse any dust o of the heater stones before
stacking them in the heater.
When stacking the stones inside the Aura heater,
ensure that the resistors remain upright and
straight.Donotbendtheresistorssothattheyare
in contact with the metal structures of the heater.
NOTE! Do not remove the bands around the
resistors. If there are two bands, one of them is
located at approximately 20 cm from the bottom
and another approximately 10–15 cm from the
top. They keep the resistors apart from each
other and prevent them from deteriorating
prematurely.
Ensuresucientaircirculationaroundtheresistors
byleavingspacesbetweenthestonesstacked
betweentheresistors.Ifthestonesarestacked
too tightly in the middle section, it will extend the
heating process and may result in the premature
failure of the resistors.
Theresistorsshouldbesurroundedbystonesonall
sides.
Note! Ensure that the resistors do not touch the
heater’s frame anywhere. There must always be
a stone between a resistor and the frame.
Donotmakeaheapofstonesontopoftheheater!
Do not use the heater without the stones!
Dentscausedbytheuserarenotcoveredby
Mondex’swarrantyorotherproductliability.When
stackingthestones,becarefulnottodentthe
heater’s metal surfaces to avoid damaging them.

5 GENERAL INSTRUCTIONS FOR USERS OF AURA HEATERS
Note
Electricalconnectionsmayonlybemadebyanelectricianwithavalidinstallationauthorisation
accordingtothecurrentregulations.TheAuraelectricheaterissuitableforuseinafamilysauna,one
(1)heaterpersaunaroom.Retaintheinstallationandoperatinginstructionsforfurtherreference.
Installation cable
UserubbercableH07RN-Fasaconnectioncable.
Additional connection options
Controlofelectricheatingwiththeheater:Theelectricheatingcontrolcableisbroughtdirectly
totheheater’sjunctionboxandfurthertotheheater’sterminalblockwitharubbercablethatis
dimensionallyidenticaltotheincomingcable.
NOTE! Failure to observe the connection instructions may cause a re hazard!
NOTE! Remove all plastic lm before using the heater!
6 THINGS TO KEEP IN MIND WHEN USING THE HEATER
First heating
Duringtherstheating,theresistorsmayemitfumes.Therefore,ensurethattheroomisproperly
ventilated. NOTE! Please also read the user instructions for the controller!
Sauna room
Alwayscheckthesaunaroombeforeswitchingtheheateron!Alwaysmakesurethatthetimerhas
switchedthepoweroafterthesettimeperiod!
Temperature control
Thetemperatureisadjustedatthecontroller(seepage12).Theactualheatingtimedependsonthe
dimensions,structureandthermalinsulationofthesauna.Thetemperatureinthesaunaroomcanbe
maintainedatthedesiredlevelwiththethermostat.Ifthetemperatureofthesaunaroombecomes
dangerouslyhighforanyreason,theoverheatingprotectorwillswitchtheheater’spowero.The
causeofoverheatingmustalwaysbeinvestigated.Thepowercanbeswitchedonagainbypressingthe
overheatingprotectorresetbutton(seepage17).
Heating time
Anexcessiveheatingtimeconsumesenergyanddoesnotimprovethesteamingproperties.Thebest
steamisachievedbykeepingthesauna’sheatingtimerelativelyshort,atabout30–60min.,according
tothesizeofthesaunaandtheheater’spower.Thesizeofthesauna,theglassdoor,windows,or
materials used may require a longer heating time.
Water thrown onto the heater
Werecommendusinghandwarmwater.Thewatershouldbefreshhouseholdwater.Throwingthe
water onto the heater sides / lower stones generates softer steam. If you want steam that feels hotter
and more intense, pour plenty of warm water on top of the heater all at once. Do not use sea water or
chlorinated water.

NOTE!Keepinmindthattheadjustablefeetaddtothetotalheightoftheheater.
Sauna room structure
The sauna and its ceiling, in particular, should have good thermal insulation, as heat tends to escape
throughtheceiling.Duetothemoisture,werecommendthatyouusealuminiumpaper.Thesizeofthe
heatershouldbeselectedaccordingtothesizeofthesauna(incubicmetres).Inadditiontocalculating
thepowerneedfortheregularsaunastructure(glasswool–foil–wood),thefollowingshouldbetaken
into consideration. If the sauna has any uninsulated wood, tile or concrete surfaces or the walls are
madeoflogs,theheaterpowerneedstobeincreased.Foreveryuninsulatedsquaremetre,theheater
powerneedincreasesbythesameamountasifincreasingthespacevolumeby1.2m3 andontimber
surfacesby1.5m3.Thefactorforglasssurfaces(glasswalls,doorsanduninsulatedstonesurfaces)is
also 1.2 m3 persquaremetre.Inborderlinecases,youshouldchooseaheaterwithhigherpower.
Thesaunaneedsecientventilationforagoodoxygenlevelandasucientamountoffreshair.
The air in the sauna needs to change at least 6 times per hour. For a sauna with an electric heater,
mechanicalventilationisthemostconvenientventilationmethod.Thesupplyairshouldbeprovided
throughaninletlocated500mm,ataminimum,abovetheheater,eitheronthewallorintheceiling.
NOTE:thedistanceofanundirectedinletairvalvefromthetemperaturesensormustbeatleast1,000
mm,whilethedistanceofaninletairvalvedirectedawayfromthesensormustbeatleast500mm.
Theexhaustvalveshouldbeplacedontheoppositewall,asfarawayfromtheheaterandascloseto
theoorlevelaspossible.Itishighlyrecommendabletoinstallanexhaustairvalveintheceilingaswell
for an easier removal of moisture after sauna sessions.
Formoreinformation,refertotheconstructioninstructionsandbuildingregulations.

Whenpurchasingspareparts,pleaserefertothename,power,serialnumberandmanufacturingdate
of the heater to ensure you receive the correct parts.
NATURAL STONE AS MATERIAL
Smallpebblesorpiecesmaycomeothenaturalstoneusedintheheater.Asthisisnotafailureof

CHANGING THE HEATER STONES
Re-stacktheheaterstonesandreplaceanyerodedstonesannually,moreoftenifusedintensively
(everythreemonthsincommercial/professionaluse).Thegoodconditionandproper,spacious
