Instantaneous Inline Water Heater
IN30
v21.3.1
Overview
Thank you for purchasing an Ara Instantaneous Water Heater. Instantaneous water heaters
are very energy ecient as they only consume energy when they are in use, so have no
standing losses. The IN30 is intended for light hand washing at a single basin and must be
used with a spray head tap.
Key Features
• Hot water for light handwashing at a single basin only
• Bare wire heating system gives fast heat up time
• Heats the water instantly as it ows through the unit
• Energy ecient – no standing heat losses
• Compact space saving design
• Energy saving – only uses the power required to deliver the chosen temperature
• Not suitable for use with thermostatic mixing valves or taps or to supply a mixer tap
The appliance must only be connected to a single phase supply.
Isolate electrical and water supply before installation.
Electrical installation must be carried out by a qualied electrician in accordance
with the latest edition of the IEE wiring regulations.
Only connect the appliance to a power supply that conforms to the specication
stated on rating plate.
The appliance must be earthed at all times.
The appliance must be permanently connected to the electrical supply through
an isolating switch with a contact separation of no less than 3mm in all poles.
Important Safety Points
Please fully read these instructions before commencing installation and follow to ensure
that installation and operation are simple and safe.

Do not use the appliance if there is any possibility of the water supply being frozen.
Never remove the cover of the appliance without rst isolating it from the electrical
power supply.
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.
The supply cord cannot be replaced by the user. If the supply cord is damaged the
appliance should be returned to the manufacturer or an authorised service agent
for replacement.

1. Installation
4
Choosing Heater Location
• Consider the risks and consequences posed by any potential leak from the product or
supply pipework in the future. Avoid installation in areas where the consequences of
a leak could be unusually severe e.g. above computer equipment.
• Consider the potential for the pipework or heater freezing and take preventative
action if required e.g. pipe lagging.
• It is advised that the heater be located as close as practical to the hot water outlet in
order to avoid unnecessary heat losses through the pipework and improve delivery
performance.
Removing and Mounting the Bracket
• The unit must be installed upright with the inlet and outlet at the top. Ensure the
bracket orientation corresponds with the unit.
• Mark and drill two holes using the bracket as a template. Use the supplied wall plugs
and screws to attach the bracket to the wall.
• Push the unit rmly onto the bracket to complete mounting.
Always ensure there are no hidden cables or pipes before commencement of
drilling.
This heater should not be installed in a location where the risk of freezing cannot
be managed.
The heater is not suitable for use with thermostatic mixing valves or taps or to
supply a mixer tap.
2. Plumbing Connection
Flush supply pipes to remove any debris before connecting the heater to the water
supply.
This unit is intended to be permanently connected to the mains water supply and
should not be connected by a detachable hose-set.
The water resistivity must not be less than 1300 Ωcm @15 C.
• The maximum water supply temperature for this heater should not exceed 30°C.
• Using the supplied washer with gauze, make a connection from the incoming
cold-water supply to the inlet side of the heater (blue collar). It is recommended a
service valve (not supplied) is tted on the incoming supply to facilitate any future
maintenance.
• Make a connection from the outlet side of the heater (red collar) to the hot water tap.
• The supplied 1.6 l/min (litres per minute) ow restrictor must be tted to the hot
water tap (compatible hot water tap required).
• Turn on the cold water supply and open the hot water tap. Allow the water to ow for
several minutes to purge all air from the heater. This step is required every time the
heater has been drained for any reason, such as routine maintenance.
• Close the hot water tap and check all connections are watertight under pressure.

3. Electrical Connection
Before switching on power to the unit the system must be full of water and tested
for leaks.
Electrical installation must be carried out by a qualied electrician in accordance
with the latest edition of the IEE wiring regulations.
The heater must be earthed.
Isolate electric and water supply before electrical installation.
Ensure all wiring provisions meet the specications of the heater as stated on the
rating label and ‘Specication’ section of this manual.
• Make connection to the electrical supply from the heater via an appropriately rated
fused spur using the cable supplied.
• Connection should be made as follows:
Green/Yellow earth wire to the terminal marked “ E” or
Brown/Red live wire to the terminal marked “L”
Blue/Black neutral wire to the terminal marked “N”

4. Operation
• Once installed and the power and water are connected, the unit requires no further
user interaction.
• To operate open the outlet. As water begins to ow through the unit heating will
commence automatically.
• An element on LED indicator will illuminate when water is owing through the unit.
• The heating performance of the heater is based on ow rates, the slower the ow
the higher the temperature uplift. The delivered temperature is the incoming water
temperature plus the temperature uplift (ow dependent).
• A ow restrictor is supplied with this heater which, when tted into the nozzle of a
tap will ensure a steady ow rate of 1.6 l/min is maintained. With this a temperature
uplift of 27°C is achieved.
• The incoming water temperature can uctuate dependent on time of year in the UK.
Winter may result in incoming temperatures below 10°C, whereas summer water
temperatures can be upwards of 15°C. It is imperative this is taken into account.
• For example the heater could deliver 42°C water in the summer (with an incoming
water supply temperature of 15°C). The same product with the same ow rate would
only be able to deliver 37°C in winter (due to a lower incoming water temperature
of 10°C). The delivered temperature will be even lower if the incoming water supply
temperature is less than 10°C.
Before switching on power to the unit the system must be full of water and tested
for leaks.
This water heater is for low ow hand washing at a single basin only.
Instantaneous heaters only heat water as it passes through the tank. Because the
maximum power of the heater is xed there is a limit to the rate at which hot water
can be delivered.

5. Cleaning and Maintenance
To clean the heater cover only use a clean damp cloth, do not use abrasive
compounds.
Electrical and plumbing components should be inspected on a regular basis by a
suitably qualied/competent person.
• Always disconnect the power before commencing any cleaning or maintenance.
• Never open the cover of the heater without rst isolating the mains power supply.
• If the ow rate drops on the heater, check the spray head and inlet gauze (tted to
the inlet plumbing connection) and clear any debris/ descale as required.
• The spray head of any tap connected to the heater should be routinely checked for
scale build up and any scale removed as necessary.

7. Troubleshooting
Problem Likely Fault(s) Solution
The LED element on indicator
light is on but the heater cannot
achieve a suitable temperature
for hand washing (water is too
cold)
Flow rate is too high Check the supplied ow
restrictor is tted in the tap
The heater will not operate (no
LED element on indicator) whilst
water is owing
Flow rate is too low Check a minimum ow of 1.2 l/
min is delivered at the outlet.
The heater will not operate (no
LED element on indicator) whilst
water is owing
Incoming water pressure is too
low
Ensure a minimum 0.05MPa
(0.5bar) pressure
The heater will not operate (no
LED element on indicator) whilst
water is owing
No power to the heater Check power supply
