1.0 IMPORTANT INSTALLATION
POINTS
1.1 The Supreme stores and dispenses water at or close to boiling
point at all times it is switched on. Due caution must be taken
when choosing a location for the product to minimise misuse.
Locate the unit over a draining board NOT over the sink or basin.
1.2PushtconnectorsDONOTgripchromedorstainlesspipe.
1.3 The Supreme is a vented water heater. The vent pipe must never
be blocked or obstructed, it must be a minimum of 15mm outside
diameterpipe.Wheretheventpipelengthexceeds3mthepipe
diameter should be increased. The vent pipe must be laid to a
continuous fall and discharge in a safe, visible position; it must
dischargeviaatundishornishaminimumof20mmabove
a draining board. The vent pipe material must be capable of
conveying boiling water. The vent pipe must never be connected
directly to a soil pipe.
1.4WhereverpossibletheSupremeshouldbesupplieddirectlyfroma
rising main. If fed from a cold water feed cistern, the cistern must
complywiththeWaterRegulationsGuide(clauseR27.2).
It should be noted that water quality may be reduced when
supplied from a cistern and additional forms of water pretreatment
may be necessary.
1.5 In hard water areas, heated water will produce limescale which will
be deposited within the heater. If this is not regularly removed it
willimpairtheoperationoftheheater.Whererapidandexcessive
scale build up is likely to occur the use of a proprietary scale
reducingdevicemaybebenecial.
1.6 The installation must be carried out in accordance with the
relevant requirements of:
•TheappropriateBuildingRegulationseitherTheBuilding
 Regulations,TheBuildingRegulations(Scotland)orBuilding
 Regulations(NorthernIreland).
•TheWaterFittingsRegulationsorWaterByelawsinScotland.
1.7TheSupremewilladjustforambient(room)temperaturesof
between1°Cand40°C.
1.8Whennotinusecaremustbetakentopreventitfreezing;if
thoughttobefrozenitmustnotbeswitchedon.Itmustbeleftto
thaw and must then be thorougly inspected to ensure it is totally
thawed and undamaged.
1.9Theunitisnotsuitableforinstallationinanareawhereawaterjet
could be used.

2.0INSTALLATION-MOUNTING
2.1 The Supreme must be vertically wall mounted using the bracket
supplied. Special precautions may be required for the protection
ofchildrenand/orinrmpersons.
2.2 Figure.1 details the outside dimensions of the Supreme unit.
A template is supplied to aid positioning the heater. It is
recommended that the unit is positioned above a draining board. If
this is not possible consideration should be given to any spillages
that may occur under the heater. A drip tray is available as an
accessory(HeatraeSadiaCodeNo.95970123).Theheater
shouldbepositionedataheighttosuittheitemsbeinglled
(asks,pans,cupsetc.).Thisislikelytopositionthebaseofthe
unit 250mm above the work surface.
2.3Sufcientroomshouldbeleftaroundtheheaterforaccessfor
maintenance and servicing. The top should not be covered as this
willreducetheefciencyoftheSupreme.
2.4Ensurethatthewallcansupportthefullweightoftheunit(see
TECHNICALSPECIFICATIONS)andthattherearenohidden
services(electricity,gasorwater)belowthesurfaceofthewall.
2.5Usingthetemplatemarkthexingpositionsandwaterandvent
entrypoints.Drillandplugthexingpositions.Fixthemounting
brackettothewallusingthetwoNo.12x2”screwsprovided
(conrm suitability of all screws and plugs for use with the
wall, if unsuitable due to wall type provide alternative xings).
2.6 If rear entry services are to be used the necessary holes for these
should be prepared prior to hanging the unit onto its bracket.
2.7Removethefrontcoverby:unscrewingthecoverxingscrews
bottom and top. Hang the Supreme onto the wall mounting
bracket.SecureanchorpointtothewallwiththeNo.8x1”long

7.0COMMISSIONING
7.1TheelectroniccontrolsystemoftheSupremehasaself
commissioning and calibration function. Once the heater is
installed and all services have been connected the unit should
requirenofurtheradjustmentbeforeuse.
7.2Checkthatallelectrical,waterandventpipeconnectionshave
been made and are secure.
7.3Replacethecoverandsecurewiththexingscrews.Ensurethe
tank discharge tube is centrally located in the outlet spout. Turn on
water and electrical supply.
7.4TheREADYindicatorwillashtoindicatetheunitisinits“self-
commissioning”mode.Thewaterintheunitwillnotbehotenough
touseatthisstage(DONOTDRAWANYWATEROFFWHILST
COMMISIONING).
7.5TheREADYindicatorwillcontinuetoashuntiltheunithas
reachedboilingandhas“self-calibrated”.AtthispointtheREADY
indicator will remain illuminated. If for any reason the calibration
procedure is interrupted it will restart after a short delay but may
result in the calibrated temperature being too low. If this occurs
switch the electrical supply OFF for several seconds and then
switchON.Thecalibrationsequencewillreset.Waitforthe
READYindicatortoremainilluminated.
7.6Theunitisnowreadytouse,however,itisrecommendedthatthe
rstfewllsbedrawnoffanddiscardedtoensurethefreshnessof
the water.
7.7Thetapsealingwasherpressurehasbeenalreadyset.Ifthetap
dripsaftercommissioningadjustthespringtensionsothatthe
handleisjustloose.
a)Removethetapbezelafterremovingthetwoscrewssecuring
it. Note: to remove the bezel the handle will have to be
operated. This will cause water to discharge from the outlet.
b)Tightenthetapheadworknut(turnclockwise)untilthehandleis
justloose.Replacebezelandsecuringscrews.Note: excessive
adjustment will dismantle the tap, if heated this would result
in the uncontrollable release of boiling water.
7.8Checkforleaks.

11
8.0 MAINTENANCE
NOTE: Maintenance must be carried out by competent persons.
Competent - i.e. trained, experienced, qualied.
Disconnect the electrical supply before removing the cover.
WARNING: electronics control by switching ‘N’ (neutral), in some
instances neutral terminations will be at 230 volts with respect to
earth.
Maintenance instructions are available from the Heatrae Sadia Ser-
viceDepartment.Telephone08448711535,Fax08448711543.
8.1 The Supreme incorporates an electronic scale conditioning
function which will reduce the rate of scale deposition in hard
water areas. However, some deposits may still occur in the
storage tank; these should be periodically removed.
8.2 The amount of usage of the unit will also determine the quality
of scale build up. A regular inspection of the tank every 6 to
12 months will provide longer life of the product and optimum
performance(removalofthesteamplateassemblywillgiveacess
tothestoragetank).
8.3 The front cover and spout will require a periodic wipe to clean any
marks/splashes from use.

11.4 TheSupremeisttedwithtwoindicatorstogiveavisual
indicationoftheunit’sstatus.
   ON Willbeilluminatedaslongastheelectricalsupplyto
the Supreme is switched on.
   READY Whenfullyilluminatedindicatesthatthestoredwater
is hot enough to use.
11.5 Ifthestoreofhotwateriscompletelywithdrawn,theowrate
fromtheoutlettapwillreducetothellingrateoftheheater.
Thisslowowrateallowstheincomingwatertobeinstantly
reheated, it does not indicate a fault with the water heater.
11.6 If the Supreme is not used for a few days the water may
become“stale”.Intheseinstancesitisadvisabletodrawoff
the contents and discard the water at least twice to remove the
“stale”water.Thiswillensurethat“freshly”boiledwaterisused
to make your drinks etc.
11.7 Similarly,ifleftunuseditispossiblethatsomescaleresidue
will collect in the outlet tap. This will cause the outlet water
toappear“milky”forashortwhile.Ifthisconditionoccurs
itisrecommendedthattherstfewcupsaredrawnoffand
discarded.
