Aquila
Instantaneous Inline Water Heater
IN96T
v23.10.9

Overview
Thank you for purchasing an Aquila Instantaneous Inline Water Heater. This 9.6 kW
appliance is to be used for hand washing at up to 2 basins, or for a single light shower, or
light dish washing. Instantaneous water heaters are energy ecient as they only consume
energy when in use, so have no standing losses. The IN96T is mains pressure with external
electronic temperature control. Bare wire heating systems oer rapid heat up times and a
near instant supply of hot water.
Conrm that the ow rate and temperature performance is adequate for your application
using the tables provided. This appliance is not suitable for use with thermostatic mixing
valves or taps or to supply a single lever mixer tap.
Please read and follow these instructions to ensure that installation and operation are as
simple and safe as possible.

1. Installation
Do not locate the appliance where the consequences of a water leak could be
unusually serious.
This appliance should not be installed in a location where freezing can occur.
This appliance is not designed for outdoor use or use in damp environments.
• When choosing a location for the appliance, consider the visibility of any leak that
might arise. This is particularly important when locating in a concealed area such as a
cupboard.
• The appliance must be mounted horizontally with the inlet and outlet connections at
the bottom of the appliance (see diagram 1).
Wall Mounting
Diagram 1
• Before attaching the appliance to the wall, consider the wiring route to the appliance.
The electrical cable can enter through the opening in the back for concealed cabling.
Knock out panels in the top right hand corner of the back plate and front cover are
available for side entry.

Ensure there are no hidden cables or pipes before commencement of drilling.
• Remove the front cover from the appliance by means of the single screw located
between the inlet and outlet ttings. The cover will lift rst from the bottom and then
unhook from the top. Carefully release the PCB lead from the main unit to completely
uncouple the cover.
• It is advised that the appliance be located as close as practical to the hot water outlet
in order to avoid unnecessary heat losses through the pipework.
• Once the preferred location has been decided, oer the appliance to the wall. Ensure
the appliance is level and mark the hole locations onto the nal mounting surface
(see diagram 1).
• Take the appliance away from the mounting surface and drill the holes marked from
the previous step.
• Insert wall plugs and oer the appliance back up to the mounting surface. Locate the
screws through the unit and into the wall plugs and screw down securely.
2. Plumbing Connection
The resistivity of the water supply must not be less than 1300 Ωcm.
Do not use a supply with incoming water temperatures greater than 60˚C.
Only connect this appliance to a water supply that meets the min/ max pressures
specied in the specications section of this manual.
This appliance is intended to be permanently connected to the water mains and
should not be connected by a detachable hose-set.
• Ensure the following criteria are met for the water supply:
Minimum ow = 2.5 l/m
Pressure min/ max = 0.1 Mpa / 0.75 Mpa
Water resistivity = ≥1300 Ωcm
• Suitable for use with pre-heated water e.g. solar heating systems to a maximum of
60°C.

• Make the plumbing connections as indicated on the front cover of the appliance:
Inlet (cold mains)
Outlet (hot tap/ outlet)
• It is strongly recommended that a service valve be tted close to the appliance on the
cold feed, this will aid future maintenance.
• The inlet is the right hand pipe and the outlet the left, when viewed from the front.
• Turn on the cold mains feed and draw water through the appliance for several
minutes by opening the hot outlet. Ensure a smooth ow of water from the outlet
to conrm all air is purged from the system before closing the tap and carefully
inspecting all connections to ensure water tightness. This step is required every time
the appliance has been drained for any reason, such as routine maintenance.

Flush supply pipes to remove any debris before connecting the appliance to the
water supply.
All pipework should be adequately earthed.

3. Electrical Connection
Do not commence electrical installation before connecting the appliance to the
water supply and verifying there are no leaks or air gaps.
The appliance must be permanently connected to the electrical supply through
an appropriately rated isolating switch with a separation in all poles.
Only connect the appliance to an electrical supply that meets the specication
detailed on the rating label.
The appliance must be earthed.
• Connection to the appliance terminal should be made as follows:
Earth cable to the terminal marked ‘E’
Neutral cable to the terminal marked ‘N’
Live cable to the terminal marked‘L’

4. Operation
• Once installed and connected to the electrical supply the appliance is ready for use.
• Once turned on the appliance will automatically power up when it detects a ow of
water through it (min 2.5 l/m).
• Due to the nature of instantaneous heaters, water is only heated as it passes through
the tank. Because the maximum power of the appliance is xed there is a limit to the
rate at which hot water can delivered.
Controls
1 - Memory (record/ recall temp setting)
2 - Increase temperature setting
3 - Decrease temperature setting
4 - Power on/ o
Selecting a temperature
• Turn on the appliance using the power on/ o. On rst installation the temperature
setting will default to 38°C. To adjust the temperature press the up/ down buttons
until the desired target temperature is displayed.
• To store a frequently used temperature setting, press and hold the“M”button. This
stores the current temperature and allows it to be recalled at any time by pressing the
“M” button.
Setting the maximum ow rate
• The ow rate is shown on the front display of the appliance in L/ MIN. If the desired
temperature cannot be met at the current ow rate the temperature display will ash
to indicate this. Adjust the ow down using the dial on the front of the appliance until
the temperature display stops ashing.
• Incoming water temperatures can vary depending on the time of year. For this reason
the maximum ow rate may need adjusting down in order to maintain a suitable
temperature during colder periods.
• The appliance has memory recall, it will revert to its previous operational state
following a power interruption.
• Once the desired temperature is selected the
appliance will manage the power in order to
ensure the temperature is not exceeded. The
current power usage is displayed by the lines at
the bottom of the display.

5. Cleaning and Maintenance
Never remove the cover of the appliance without rst isolating from the electrical
power supply.
The appliance should only be installed and maintained by a competent person in
accordance with any local electrical and plumbing regulations.
Do not use abrasive chemicals or cloths to clean this appliance.
Isolate the appliance from the electrical and plumbing supply before performing
any maintenance task.
The appliance should be drained if it will be switched o or unattended for
any length of time, particularly during the colder months of the year where the
possibility of freezing temperatures exists.
Ensure any future maintenance or modications to the plumbing system also
complies with the guidelines in these instructions.
Keep records of maintenance and ensure any future occupier of the building is
fully aware of the content of these instructions.
• Visually inspect the appliance and its immediate surroundings regularly for any signs
of water escape that might indicate the product may be nearing the end of its natural
life.
• Use a soft damp cloth when cleaning, avoid excessive use of liquids.
• Check outlet of any tap connected to the heater at regular intervals and remove any
build up of scale that might obstruct the ow rate of water through the appliance.
Overheat Protection
• In the unlikely event of a malfunction, the appliance is tted with a manual reset
thermal cutout. This is located under the cover near the top of the heating chamber.
To reset press the push button located in the centre of the device.
• Once reset, operate the appliance and ensure there is no underlying fault which is
causing the water to overheat.
