1.0 GENERAL INSTALLATION
POINTS
1.1 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 pre-treatment may be
necessary.
1.2 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.
1.3 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.

2.0 INSTALLATION - LOCATION
2.1 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. It is
recomended that the unit be mounted in such a manner that the
operator can stand directly facing the unit with the controls at a
recommendedheightfromtheoortothedraw-offtapof1200mm
+/- 100mm.
2.2Sufcientroomshouldbeleftaroundtheheatertoallowaccessfor
maintenance and servicing.
2.3 Install the unit on a surface suitable for near boiling temperatures
and the working weight of the unit.

4.0 INSTALLATION - WATER SUPPLY
4.1AWRASlistedisolatingvalveshouldbettedtothecoldsupplyto
facilitate servicing the heater.
4.2 Before connecting the unit the supply pipe must be thoroughly
ushed out to ensure that foreign matter does not block or enter
the solenoid valve.
4.3 The unit must be connected to a potable water supply using the food
grade hose provided, in a manner which complies with UK water
regulations. The hose should be connected to a ½” (15mm) drinking
water supply via an appropriate isolating valve. The supply must
provide a constant pressure of between 20 KPa and 1000 KPa (0.2
to10Bar),viaanisolatingstopcockttedneartheunit.
4.4 If the water supply contains excessive solids in suspension it is
recommendedthatanemesh“inline”waterlteristtedinthe
pipe work after the stop cock. Failures due to scale and sediment
are not covered by the warranty.
5.0 INSTALLATION - VENT PIPE
NOTE: It is not advisable to create a permanent connection to the
vent which cannot be removed if maintanence is required.
5.1 Thevent/overowpipemustbeextendedandlaidwithacontinuous
fall, discharging to a safe and visible point. The pipe should not be
directly connected to a closed waste, as taste problems may occur
and should never be allowed to become blocked or restricted. One
way this could be connected is via a tundish arrangement. The
vent pipe material must be capable of conveying boiling water. If
themachineisoperatedwithouttheoverllpipebeingextendedas
advised, any subsequent damage incurred will be the responsibility
of the installer.

7
6.0 INSTALLATION - ELECTRICAL
REQUIREMENTS
6.1 Theunitissuppliedwithattedplugandleadandshouldbeplugged
into a 240v 13A electrical socket, capable of carrying a load of 3kW. If
the supply cord is damaged it must be replaced by the manufacturer,
itsserviceagent,orsimilarlyqualiedpersonsinordertoavoida
hazard.
6.2 The installation of a residual current device (RCD) having a rated
residual operating current not exceeding 30 mA is advisable.
6.3 This appliance must be earthed.
6.4 The installation, supply cable and circuit protection must conform
to the latest BS7671 ‘Requirements for electrical installations’ (IEE
Wiring Regulations).
6.5 IftheSupremeisnotusedforsignicantperiodsoftimerunningcosts
can be reduced by switching the unit off. It is recommended that this is
done automatically by incorporating a suitable timeswitch in the supply
to the unit. The use of accessory No. 95 970 124 is recommended. The
timeswitch can then be set to switch the unit on for a suitable period
to allow it to heat up before it is next to be used. NOTE:If a timeswitch
is used, it must be capable of switching 13 Amps resistive load.

7.0 COMMISSIONING
7.1 Check that all electrical, water, and vent pipe connections have been
made and are secure.
7.2 Turn on the water supply and then switch on the electrical supply.
Ensure that the On/Off switch is in the On position. (Located at the
rear).
7.3 TheWait/Readylightwillashyellow(indicatingbelowtemperature)
andtheunitwillslowlyllwithwater(1.2L/Min).Whenwaterpasses
the low level sensor (just below tap level) the element will also be
energised. When the normal operating water level is reached the
solenoid will be disabled and the element will continue to heat the
unit until the full operating temperature has been reached. At this
point the Wait/Ready light will show solid orange indicating that the
unit is full and up to temperature.
7.4 Check for leaks.
Subsequent Use
7.5 Aftertheunithasnishedthecommissioningcycle,andwateris
drawn from the tap, water will be replaced in short cycles (small
amount of water and then heat). The solenoid and element will never
be on at the same time unless the unit is switched off and on again
(re-setting commission mode). In normal use the unit will always be
at operating temperature indicated by the Wait/Ready light showing
asolid(notashing)colour.Whentheunitisfullandready,thelight
will be orange and when the unit is only part full the light will be
yellow.

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 240 volts with respect to
earth.
8.1 The production of scale is a natural phenomenon and commonly
occurs in hot water systems. The nature of the scale produced and
its rate of formation varies widely throughout the country.
8.2 To ensure continuous, reliable operation, the unit should be regularly
de-scaled by a suitably qualied engineer. Suitable chemical de-
scalants must only be used if the manufacturers recommendations
are strictly adhered to. This is to prevent health and safety issues,
taste problems and potential damage to the appliance. Misuse of
such chemicals is not covered by the product warranty.
8.3 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.
8.4 The amount of usage of the unit will also determine the quantity 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).

11
9.0 SERVICE
9.1 When the green service indicator light on the front of the unit is
showing solid colour, the machine has been starved of water for in
excess of 20 minutes and the solenoid valve has been disabled to
prevent damage to the solenoid coil through overheat. To re-energise
the solenoid, the unit must be disconnected from the electrical supply
andthenswitchedbackon,afterrstreinstatingthewatersupply.
9.2 Iftheunitrequiresservicingtheserviceindicatorwillashasequence
of light pulses. A 2 times or 3 times light pulse generally indicates
that the low or normal level sensors require de-scaling.
9.3 A 4 times light pulse means the water level has reached the high
level sensor and the likelihood is that the normal level sensor requires
de-scaling,orthemachinehasover-lledduetodebristrappedin
the solenoid valve. The debris can be removed by drawing plenty of
water from the dispense tap, causing the solenoid valve to operate
andushouttheobstruction.Themachinewillresetitselfoncethe
problem has cleared. If this does not rectify the problem, turn off
thewatersupplyandremovetheexiblehosetocheckfordebrisin
thesolenoidvalve’slter.Theunitcanbeusednormallywhilethe
serviceindicatorisashinga4timespulse.Forfurtherassistance,
contact the Heatrae Sadia Service Department, telephone [phone]
1535, fax [phone].
9.4 To gain access to internal components, the lid must be removed.
The lid ‘pops’ off in an upward motion. Beneath the lid there are four
screws holding the steam trap in place. Removing these will allow the
steam trap to be removed and access to the tank will be gained.
To gain access to the rear components the rear panel must be
removed which is held in place by six screws.
NOTE: Whenever the body lid has been removed from the unit a new
lid gasket may be required to ensure a steam-tight joint. Damage to
the unit caused by a poor lid seal is not covered by warranty.

12
9.5 Scale deposits should be removed from all internal surfaces,
particularly the heating element, thermistor, and level sensors by
gently tapping or scraping. If the deposits are soft, use a nylon
padandushout.Abrasivecleaningmaterialscontainingscouring
powders and detergents must not be used, as such materials can
cause taste problems.
9.6 Suitable chemical de-scalants must only be used in accordance with
the manufacturers recommendations. This will prevent health and
safety issues, taste problems, and potential damage to the appliance.
All trace of these chemicals must be removed from the appliance
before re-commissioning the unit . Misuse of such chemicals is not
covered by the product warranty.
IMPORTANT Before re-commissioning the unit, it is important that all
scale and moisture is removed from the level sensor insulating
gaskets to avoid a false signal being transmitted through the scale
to the unit body. Failure to remove this scale and/or moisture could
cause the sensor to indicate to the PCB that water is covering the
element, whether or not water is present. In this situation the PCB
could energise the element causing failure. If in doubt, protect the
elementbyhandllingwithwatertothelevelofthedraw-offtap
before switching on the electrical supply to the unit.
9.7 General function
  The printed circuit board (PCB) controls the heating and lling
functions of the unit by monitoring the thermistor and level sensors.
The PCB also controls the external light unit to indicate the current
state of the appliance. Red and yellow LED’S on the circuit board
indicate whether the PCB has energised the element or solenoid
respectively.
Should an element fail and need to be replaced, it may be necessary
to replace the lid gasket to ensure a steam-tight joint. Note: the
element has a permanent ‘Live’ feed, and the ‘Neutral’ is switched.

13
9.8 Printed Circuit Board replacement (PCB)
In the event of a PCB failing and a replacement being required, full
instructions will be supplied. It is important to note however, that the
Triac PCB must be securely mounted against the copper heat-sink
to ensure reliable heat dissipation. Heat transfer compound is also
supplied with all replacement circuit boards.
9.9 Adjusting the Water Temperature Set Point
The temperature potentiometer (Pot) is pre-set at Heatrae Sadia and
will only require adjustment in exceptional circumstances. Contact
Heatrae Sadia for advice.
Water boils at different temperatures depending on barometric
pressure. The temperature should not be tuned higher than 98°C,
or over boiling may occur during low barometric pressure conditions
causing the unit to trip the overheat cut-out device.
9.10 On / Off Switch
The On / Off switch is positioned at the rear of the machine. When
in the off position the unit will cease to function & the light on the
fascia will go out.
NOTE: This switch must not be used to isolate the electrical supply for
servicing / maintenance. When maintaining / servicing the unit the
power cord must be removed from the mains supply.
