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 the draining board NOT over the sink or
basin.
1.2 The Supreme is a vented water heater. The vent pipe must never
be blocked or obstructed. The vent pipe 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. The vent pipe material must be capable of
conveying boiling water. The vent pipe must never be connected
directly to a soil pipe.
1.3 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 Supply (Water Fittings) Regulations
1999, Schedule 2, Section 7 , Paragraph 16.
It should be noted that water quality may be reduced when
supplied from a cistern and additional forms of water
pretreatment may be found to be necessary.

2.0 INSTALLATION - MOUNTING
2.1 The Supreme should be vertically wall mounted using the bracket
supplied. Special precautions may be required for the protection
of children, aged or infirm persons.
2.2 Fig.2 details the outside dimensions of the Supreme unit. A
template is also supplied printed on the packaging 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 ( eatrae
Sadia Code No. 95.970.123). The heater should be positioned at
such a level that suitable tea, coffee, etc. making utensils can be
placed under the outlet spout (approximately 250mm above the
work surface is suggested).
2.3 Sufficient room should be left around the heater for access for
maintenance and servicing. Do not block the air flow louvres at
the top and bottom of the backplate as this will restrict the cooling
air flow through the unit.
2.4 Ensure that the wall can support the full weight of the unit (see
TEC NICAL SPECIFICATIONS) and that there are no hidden
services (electricity, gas or water) below the surface of the wall.
2.5 Mark the fixing positions and water, vent and electrical supply entry
points. Drill and plug the fixing positions. Fix the mounting
bracket to the wall using the two No.12 x 2” screws provided.
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.

5.0 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.
5.1 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.
5.2 The nominal cross sectional area of the supply cable should be
1.5mm2 minimum.
5.3 If using bottom cable entry, the thinned section in the backplate
should be removed using a pair of pliers. Any sharp edges should
be smoothed with a file. The outer sheath of the cable must be
secured using the cable clamp provided. It is not necessary to
clamp a rear cable entry.
5.4 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.
5.5 If the Supreme is to be unused for significant periods of time (e.g.
overnight or at weekends) 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 eatrae 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: The timeswitch must be capable of switching
13 Amps resistive load.

6.0 COMMISSIONING
6.1 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.
6.2 Check that all electrical, water and vent pipe connections have
been made and are secure.
6.3 Replace the front cover and secure with the fixing screws. Turn on
water and electrical supply.
6.4 The ON indicator will flash to indicate the unit is in its “self-
commissioning” mode. After a while the ALF FULL indicator will
illuminate to indicate the unit is half full of water. After a further
period the FULL indicator will illuminate to indicate the unit is full of
water. The water in the unit will not be hot enough to use at this
stage.
6.5 The ON indicator will continue to flash until the unit has reached
boiling and has “self-calibrated”. At this point the TEMPERATURE
READY indicator will illuminate and the ON indicator will stop
flashing and remain illuminated.
6.6 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.

7.0 MAINTENANCE
NOTE: It is recommended that any maintenance be carried out by
competent persons. Disconnect the electrical supply before
removing the cover.
Maintenance instructions are available from the eatrae Sadia Service
Department. Telephone [phone] , Fax [phone]
7.1 The electronic control system of the Supreme has a self-diagnostic
feature which determines if the unit is operating satisfactorily. If it
is not operating correctly the nature of the fault is ascertained and
a fault mode is indicated.
7.2 If steam or boiling water discharges from the vent pipe the
Supreme will switch off. Other critical faults are indicated by the
indicators flashing. The cause of the fault will be indicated by
which is flashing (see Section 8.0 FAULT FINDING). A critical fault
would render the unit unsafe to use and so will deactivate both the
element and solenoid valve.
7.3 The Supreme incorporates an electronic scale conditioning
function which will reduce the rate of scale deposition in hard
water areas. owever, in extreme circumstances some deposits
may still occur in the storage tank, these should be periodically
removed.

10.0 USER INSTRUCTIONS
10.1 Once installed the filling and heating cycles of the Supreme are
completely automatic.
10.2 To dispense the water the tap handle should be pulled down and
towards the user, a suitable container having been placed under
the outlet spout. 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.
10.3 The tap handle is spring loaded so that when released it will
spring back to the “off” position (no flow).
10.4 The Supreme is fitted with four indicators to give a visual
indication of the units status.
ON Will be illuminated as long as the
electrical supply to the Supreme is
switched on.
TEMPERATURE READY When illuminated indicates that the
stored water is hot enough to use.
ALF FULL When illuminated indicates that the
unit is at least half full.
FULL When illuminated indicates that the
unit is at its full capacity.
In addition to the above the indicators will alert the user to a fault
condition on the unit as follows (refer to the Fault Finding chart for
possible causes):
ON light flashes. Unit has not filled within a programmed time
limit.
TEMPERATURE READY light flashes. A temperature control fault
has occurred.
ALF FULL light flashes. alf full level sensor malfunction.
FULL light flashes. Full level sensor malfunction.
The above faults may be critical to the safe operation of the unit,
so the electronic unit will deactivate the element and solenoid
valve. The nature of the fault should be ascertained and rectified
before further use.
11991 36005826 XPRESS 8/8/03 7:37 AM Page 14 (Black plate)

15
10.5 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.
10.6 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.
10.7 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.
