BOIL AND CHILL MODEL (INCLUDING BOIL AND AMBIENT)
1.0 INTRODUCTION
Thank you for purchasing a Heatrae Sadia Aquatap unit. This unit is manufactured to the highest
standards and has been designed to meet all the latest relevant constructional and safety specications.
The Aquatap unit must be installed (see sections 3.0, page 7 to 9.0, page 14), commissioned (see
section 10.0, page 15) and maintained (see section 12.0, page 20) by a competent person. Please
read and understand these instructions prior to installing your Aquatap unit. Following installation
and commissioning of the unit, the operation of the Aquatap should be explained and demonstrated
to the user. Instructions for use are explained in section 11.0, page 19. These instructions should
be left with the user for future reference.
This appliance can be used by children aged from 8 years and above and persons
with reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, if they have been given supervision or instruction concerning use of the
appliance in a safe way and understand the hazards involved. Children shall not play
with the appliance. Cleaning and user maintenance shall not be made by children
without supervision.
IntelliboilTMPlus is a patented control system for managing the efciency of the Aquatap’s boiling cycle.
It regularly brings the contents of the water container to boil in response to ongoing user demand.
However, when there has been no draw off for a period of one hour, IntelliboilTMPlus steps back the
stored water temperature. This avoids unnecessary boiling - possibly for a number of hours or even
days - until there is renewed user demand. When this occurs, the boiling cycle resumes.
The appliance is intended to be used in commercial applications such as (but not limited to):
• Hotel conference suites
• Waiting rooms
• Staff room kitchens/rest rooms

3.0 IMPORTANT INSTALLATION POINTS
3.1 The Aquatap unit must be installed in accordance with the relevant requirements of:
• The appropriate building regulations by application of either The Building
Regulations (England and Wales), The Building Regulations (Scotland) or
The Building Regulations (Northern Ireland). In territories other than those listed
the local regulations in force must be complied with.
• The Water Supply (Water Fittings) Regulations (England, Wales and Northern
Ireland) or The Water Byelaws in Scotland.
3.2 The Aquatap stores and dispenses water at or close to boiling point whilst
switched on. Due caution must be taken when choosing a location for the product to
minimise any possible misuse. The dispenser tap should be located so that it
discharges over a sink or mounted on its own purpose designed drip tray (available as
an accessory, product code 95970138).
3.3 The Aquatap is a vented water heater. The vent pipe must never be blocked,
obstructed or removed. Warning: In the event of a unit malfunction, steam may vent
from the vent pipe for a short period of time (see g. 5, page 11 for position of vent
pipe).
3.4 Wherever possible the Aquatap should be supplied directly from the cold mains
supply. 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 pre-treatment of the water
supply to the Aquatap (eg, ltration) may be necessary.
Note: In order to meet the minimum supply pressure requirements of the Aquatap,
any cold feed cistern must be a minimum of 5 metres above the unit.
3.5 In hard water areas, heated water will produce limescale which will be deposited in
the heater. If this is not regularly removed it will impair the operation of the Aquatap
unit. Where rapid and excessive scale build up is likely to occur, the use of a
proprietary scale reducing device on the water supply to the unit may be benecial.
3.6 The unit must not be installed where it is liable to freeze. If the unit is thought to be frozen
it must not be switched on. It should be allowed to thaw and must then be thoroughly
inspected to ensure it is undamaged.
3.7 The unit is not suitable for installation in an area where a water jet could be used.
3.8 The water chiller must be installed and commissioned in accordance with
SuperChill 30B Fitting Instructions and User Guide 36006126.

4.2 Refer to g. 1, page 4 for dimension details of the Aquatap water heating unit and the
relative positions of the water and electrical connections.
4.3 The Aquatap heater unit must be located beneath the dispensing tap.
It must be possible to connect the exible hoses and electrical connection cable from the
dispensing tap to the OUTLET and VENT connections on the Aquatap unit. The pipes
must not be lengthened. The dispenser tap can be positioned so it discharges into a sink
or mounted on its own purposed designed drip tray (available as an accessory, product
code 95970138).
4.4 Sufcient room should be left around the unit to allow access for maintenance and
servicing (see g. 1, page 4). Two of the case xing screws are located on the top
rear edge of the unit; it must be ensured that these can be accessed in order to facilitate
removal of the front cover for maintenance and servicing. An ambient temperature
between 5ºC and 35ºC is required in the cupboard housing the Aquatap water heating
unit. Air circulation must be provided so air can ow through the cupboard (see diagram
below). If adequate air circulation is not provided this will cause calibration problems
and the Aquatap water heating unit will not function correctly.
4.5 The Aquatap water heating unit is supplied with a moulded plug tted to a 1.2 metre
electrical supply cable. If the cable needs to be lengthened this must be completed by a
qualied electrician. Refer to section 9.0, page 14 - INSTALLATION – ELECTRICAL
REQUIREMENTS for full details of the electrical installation.

5.0 INSTALLATION - WATER SUPPLY
5.1 The INLET connection to the Aquatap water heating unit is located on the top rear
of the unit (see g. 1, page 4). It is threaded ½” BSP male parallel at faced tting.
Any connection must use a suitable WRAS listed sealing washer. It is not possible
to make a compression connection directly to the INLET connection.
5.2 A WRAS listed isolating valve must be tted in the cold water supply to the unit to
facilitate servicing the heater.
5.3 Install Filter kit as per lter instructions 36005847
5.4 If using hard piping, ensure this is not routed where it may impair access to the case
xing screws or prevent access and/or removal of parts for servicing or maintenance.
5.5 The use of a WRAS listed exible braided hose assembly is recommended for the nal
connection to the heater to allow for easy access/removal should it be required.
5.6 The hot OUTLET connection from the Aquatap water heating unit is located on the top
rear of the unit (see g. 1, page 4). It is a hose spigot to which the exible hot
supply hose to the dispensing tap is attached. Refer to section 8.0 INSTALLATION –

10.7 The “READY” indicators will continue to ash until the heater unit is full and has self -
calibrated to the correct boiling temperature. At this point, the “READY” indicators will
stop ashing and remain illuminated. If the calibration procedure is interrupted the light
will continue to ash until the unit has calibrated. Wait until the ready indicators remain
illuminated before use.
Do not draw any water off during the self - commissioning mode.
10.8 The Aquatap heater unit and dispenser tap should now be ushed to remove any
installation residues and pasteurise the surfaces in contact with the water.
10.9 To dispense hot water press the button marked “SAFETY” on the dispenser tap (the
safety button must be released before the dispense button can be activated. You have a
5 second window in which to start dispensing) followed by the HOT water button (red).
The hot water dispensing button must remain pressed for the water to ow. If released,
it will be necessary to press the “SAFETY” button again before more water can be dis
pensed. To dispense chilled/ambient water, press the CHILLED/AMBIENT button (blue).
The safety button does not have to be pressed for chilled/ambient water. If both the
CHILLED/AMBIENT and HOT water buttons are
pressed simultaneously the CHILLED/
AMBIENT button will always take preference.
10.10 Following ushing, it is recommended that the
power is switched off and the Aquatap casing
removed to check for any internal leaks.
Always disconnect the electrical supply
before removing the cover.
If there are no leaks evident, replace and secure
the front casing. Switch on the electrical supply.
The “READY” indicator will illuminate on the Aquatap unit and
dispenser tap. The “READY” indicators will ash for a short time as the unit re-calibrates
and checks the correct ll level. When the “READY” indicators stop ashing and remain
solid, the Aquatap unit will be ready for use.
10.11 After commissioning, the following should be explained to the user:
• Correct operation of the Aquatap water heater and dispensing tap.
• Advise the position of the water and electrical isolation points.
• How to identify if there is a malfunction of the unit. Explain that in the event of a
malfunction of the unit or dispenser tap, any maintenance or servicing must only
be carried out by a competent installer.
• Explain the necessity for regular maintenance of the system to ensure continued
safe and efcient operation.
• Draw the users attention to section 11.0, page 19 of these instructions which
detail the correct use of the system.

11.0 USER INSTRUCTIONS
11.1 Once installed and commissioned, the lling and heating cycles of the Aquatap are
completely automatic.The indicator lights on the dispensing tap will indicate the status
of the system. If the “READY” light is ashing this indicates that the unit is
self-calibrating. The Aquatap will enter this mode after any period of the electrical
supply being switched off. DO NOT draw off water whilst the “READY” light is
ashing. When the “READY” light stops ashing and remains illuminated, the unit will be
ready to dispense boiling water.
11.2 Hot water drawn from the dispensing tap will at all
times be 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 inrm persons.
11.3 Hot water cannot be dispensed unless the safety
lock is turned off. The button marked “SAFETY”
should be pressed before the hot water dispensing
button.The dispensing button must be held in the
pressed position to continue dispensing. If it is
released, the “SAFETY” button must be pressed
again before more hot water can be dispensed.
If either the HOT button or CHILLED/AMBIENT button is pressed, the other button will
not activate.
11.4 Ambient/chilled water is dispensed by pressing the CHILLED/AMBIENT water
dispensing button. The safety button does not need to be pressed for dispensing
chilled/ambient drinking water.
11.5 In the unlikely event that the full store of hot water is completely drawn off from the
Aquatap, the pump will stop and ow from the dispenser will be interrupted. Should
this happen, the “READY” indicator will ash. After a few minutes, the unit will have
re-lled to a level where hot water can again be drawn off. This will be indicated by the
“READY” indicator remaining lit. If air becomes captive in the pump, operate the dispense
sequence to remove the air trapped in the pump. It does not indicate a fault with the
heater.
11.6 If the Aquatap is not used for a few days, the stored water may become “stale”. In
these instances it is advisable to draw off and discard the entire contents to ush
through the “stale” water. This will ensure that freshly boiled water is available for
dispensing.
11.7 Occasionally some scale residue may be drawn from the unit with the dispensed water
which could cause the water to appear “milky” for a short while. This is completely
harmless and will quickly clear if left to stand. Alternatively a few cups of water can be
dispensed and discarded until the water ows clearly.

10.12 The commisioning record should be completed (see section 15.0, page 31).
10.13 These instructions should be left with the user for future reference.

12.0 MAINTENANCE
Note: Any maintenance on the Aquatap water heater, dispensing tap or SuperChill 30B
must be carried out by competent persons. A competent person will be trained, experi-
enced and qualied to work with this type of appliance.
Always disconnect the electrical supply before removing the cover.
Any water contained in the water heater may be very hot. Exercise caution when
removing.
Warning: The electronics control by switching the neutral (N). In some
instances, neutral terminations will be at 230 - 240V~ with respect to earth.
12.1 The Aquatap 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.
12.2 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 access to the
storage tank).
12.3 Periodic cleaning of the screen vent lter within the inlet pipe will prevent debris
collecting which could result in reduced performance.
