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 fit 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 finish 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 (see Supreme
Maintenance Plan). Where rapid and excessive scale build up is
likely to occur the use of a proprietary scale reducing device may
be beneficial.
1.6 The installation must comply with the relevant sections of the
Water Regulations, Building Regulations and BS 7671 (IEE
Wiring Regulations) in force at the time.
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.

5
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 infirm persons. The appliance is not intended
for use by young children or infirm persons without supervision.
Young children should be supervised to ensure that they do not
play with the appliance.
2.2 Fig.2 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 filled (flasks, pans, cups etc.). This is likely to
position the base of the unit 250mm above the work surface.
2.3 Sufficient room should be left around the heater for access for
maintenance and servicing. The top should not be covered as
this will reduce the efficiency 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 fixing positions and water and vent
entry points. Drill and plug the fixing positions. Fix the mounting
bracket to the wall using the two No.12 x 2” screws provided
(confirm suitability of all screws and plugs for use with the
wall, if unsuitable due to wall type provide alternative
fixings).
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 fixing screws
(two at the bottom), hinging the cover slightly forward and then
lifting it clear. Hang the Supreme onto the wall mounting bracket.
Secure anchor point to the wall with the No.8 x 1” long screw
(provided).

4.0 INSTALLATION - WATER SUPPLY
4.1 Select appropriate push fit connector for chosen entry position:
Bottom entry water - 15mm x 15mm 90° elbow.
Rear entry water - 15mm x 15mm straight.
Note: stainless or chromed pipes do NOT provide secure
connections with push fit fittings (use copper pipe at joints).
4.2 Push the connector fully home (28mm engagement) onto the
solenoid valve inlet spigot. To remove a push fit connector the
collar (collet) should be pushed towards the body of the fitting
whilst pulling the connector off the pipe.
4.3 If the inlet pipe run is horizontal and beneath the unit ensure it
does not prevent access to the case screws.
4.4 Connect the inlet pipe to the push fit connector ensuring it is fully
pushed home (28mm engagement). After connection DO NOT
make soldered joints in the pipework close to the heater, as the
heat may damage the connector or the water heater itself.
4.5 A WRAS listed isolating valve should be fitted to the cold supply to
facilitate servicing the heater.
4.6 Push fit connectors are supplied to allow either bottom or rear
entry of services. If a combination of entry points are required an
additional connector will be required as follows:
Bottom inlet, rear vent 15mm x 15mm elbow
(Heatrae Sadia part no. 95 607 510)
Rear inlet, bottom vent 15mm x 15mm straight
(Heatrae Sadia part no. 95 607 509)
5.0 INSTALLATION - VENT PIPE
5.1 Select appropriate push fit connector for chosen entry position:
Bottom entry vent - 15mm x 15mm straight
Rear entry vent - 15mm x 15mm 90° elbow
5.2 Push the connector fully home (28mm engagement) onto the vent
pipe connection.
5.3 Connect the vent pipe to the push fit connector ensuring it is
pushed fully home (28mm engagement). Refer to the vent pipe
requirements detailed in IMPORTANT INSTALLATION POINTS.
If a bottom entry vent pipe is used the pipe must terminate below
the unit, in a safe visible position. After connection DO NOT make
soldered joints in the pipework close to the heater, as the heat
may damage the connector or the water heater itself.

6.0 INSTALLATION - ELECTRICAL
REQUIREMENTS
WARNING: This appliance must be earthed. It is suitable for a.c.
supply only. Disconnect the electrical supply before removing
the cover. Installation must be in accordance with the current
local Wiring Regulations.
6.1 Supremes must only be connected via Fixed Wiring (a plug and
socket must not be used).
6.2 A double pole isolating switch, with a contact separation of at least
3mm in both poles, should be incorporated in the electrical supply.
The supply should be fused 13 Amp.
6.3 The nominal cross sectional area of the supply cable must be a
minimum of 1.5mm2.
6.4 The outer sheath of the cable must be secured using the cable
clamp provided, unless using rear cable entry.
6.5 Strip the outer sheath from the cable for a maximum of 60mm.
Prepare and consolidate the ends and connect the cable to the
terminal block as follows:
BROWN or RED wire to terminal marked L.
BLUE or BLACK wire to terminal marked N.
GREEN/YELLOW or GREEN wire to terminal marked
If using “Twin and Earth” cable the bare earth wire must be
sleeved.
6.6 If Supremes are to be unused for significant periods of time
running costs can be reduced by switching the units off. It is
recommended that this is done automatically by incorporating a
suitable timeswitch in the supply to the unit. The use of Heatrae
Sadia 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: A
timeswitch must be capable of switching 13 Amps resistive load.

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 fixing 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 flash 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.
7.5 The READY indicator will continue to flash 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
first few fills 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.

8.0 MAINTENANCE
NOTE: Maintenance must be carried out by competent persons.
Competent - i.e. trained, experienced, qualified.
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
Service Department. Telephone [phone] , Fax [phone]
8.1 The electronic control system of the Supreme has a self-
diagnostic feature which determines if the unit is operating
satisfactorily. It will automatically calibrate for water quality and
temperature.
8.2 If steam or boiling water discharges from the vent pipe the
Supreme will switch off. A critical fault would render the unit
unsafe to use and so will deactivate both the element and
solenoid valve.
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.

11.0 USER INSTRUCTIONS
11.1 Once installed the filling and heating cycles of the Supreme are
completely automatic.
11.2 To dispense water, a suitable container having been placed
under the outlet spout, the tap handle should be pulled down
and towards (or pushed away from) the user. The water
dispensed will at all times be boiling or close to boiling point so
due caution must be taken when using the product, especially if
it is likely to be used by children, aged or infirm persons.
11.3 The tap handle is spring loaded so that when released it will
spring back to the “off” position (no flow).
11.4 The Supreme is fitted 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 flowrate
from the outlet tap will reduce to the filling rate of the heater.
This slow flowrate 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 first few cups are drawn off and
discarded.

17
