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
TheAQUATAP unit must be installed (see Sections 3.0, page 7 to 9.0, page 14), commissioned (see
Section 10.0, page 14 ) and maintained (see Section 12.0, page 18) 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 17. These instructions should
be left with the user for future reference.
This appliance is not intended for use by persons (including children) with reduced physical, sensory
or mental capabilities, or lack of experience and knowledge, unless they have been given supervision
or instruction concerning the use of the appliance by a person responsible for their safety. Children
should be supervised to ensure that they do not play with the appliance.
IntelliboilTMPlus
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:

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 such 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 FIG. 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
be reduced when supplied from a cistern and additional pre-treatment of the water
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
3.6 The AQUATAP unit will adjust for ambient air temperatures of between 1°C and 40°C
3.7 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.
3.8 The unit is not suitable for installation in an area where a water jet could be used.

4.0 INSTALLATION – MOUNTING THE WATER HEATING UNIT
4.1 The AQUATAP water heating unit is free standing and must be mounted on a level
surface. If being mounted in a cupboard, on a shelf or false base, ensure that
the supporting surface can carry the full weight of the unit (see TECHNICAL
SPECIFICATIONS Section 2.0, page 4)
4.2 Refer to FIG. 1, page 4 for details of the dimensions 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

DISPENSING TAP MOUNTING below for full details of how to mount and connect the
dispensing tap to the water heating unit.
6.2 The VENT will ensure that any excess steam or pressure is safely vented to
atmosphere in the event of a fault with the unit. IT MUST NOT BE BLOCKED,
OBSTRUCTED, DISCONNECTED OR REMOVED.
7.0 INSTALLATION – DISPENSING TAP MOUNTING
7.1 The dispensing tap supplied is suitable for mounting onto a worktop or counter
surface. It should be positioned such that it discharges into a sink or drip tray (FIG. 6,
page 11 for tap dimensions). A purpose designed drip tray is available as an
accessory (order Product Code 95970138). If this is used, then the instructions
supplied with the drip tray accessory should be followed.
7.2 Cut a 35mm diameter hole in the position selected through the worktop or counter
surface or use the template provided if using the drip tray. NOTE: Do not mount the
dispenser directly onto a stainless steel sink.

7.4 Ensure the sealing washer provided is correctly located on the base of the tap. A light
application of clear silicon sealant on the base of the tap and the sealing washer will

8.0 INSTALLATION – DISPENSING TAP CONNECTION
8.1 The hot supply hose should be connected to the OUTLET hose spigot of the AQUATAP
water heating unit. The hose should rise continuously from the heater to the tap without
kinks or twists. If necessary it can be cut to a shorter length, but it should never be
lengthened. The hose should be secured in place on the spigot using the clips provided.
Warning, only use the hose supplied with the unit or a temperature rated WRAS
approved hose. Spare hose and clips can be ordered, part number 95 607 364.
8.2 The VENT hose should be connected to the VENT hose spigot of the AQUATAP water
heating unit. The hose should rise continuously from the heater to the tap without kinks
or twists. If necessary it can be cut to a shorter length, but it should never be lengthened.
The hose should be secured in place on the spigot using the clips provided.

The electrical supply cable must be connected to the electrical supply via a double pole
isolating switch with a contact separation of at least 3mm in both poles. The electrical
supply should be fused 13 amp.
9.4 The AQUATAP dispensing tap must be connected to the water heating unit by means of
the black sheathed control cable. The cables from each unit are terminated in a mating

be reduced by switching the unit off. It is recommended that this is done automatically by
incorporating a suitable time switch in the electrical supply to the unit. A suitable time
switch is available as an accessory (order Product Code 95970124) which can be
set to switch the unit on for a suitable period of time to allow it to reheat before it is next
used. NOTE: If selecting an alternative time switch it must be capable of switching
a 13 amp resistive load.
10.0 COMMISSIONING
10.1 The AQUATAP heater incorporates an electronic controls system which has a self
commissioning and calibration function. No installer or user adjustment is necessary
before use.
10.2 Check that all electrical, water and vent pipe connections have been correctly made and
are secure.
10.3 To remove the main cover, unscrew the fascia securing screw and remove the fascia,
remove two top cover securing screws and four cover securing screws. The cover
can now be pulled back from the heater assembly. Caution should be taken here as the
wires, make sure the LED with the orange wire is at the top and the LED with the
blue wire is at the bottom.
10.4 If the cover has been removed, this should be replaced and secured with the supplied
AQUATAP heater.
10.5 Once commissioned it is advisable to insulate both hot and cold hoses.
