Thank you for purchasing a Hyco instantaneous water heater. Instantaneous
water heaters are very energy efficient since they only consume energy
when they are used and so have no standing losses. The IN96T is a mains
pressure multipoint instantaneous water heater with electronic temperature
control, designed for handwashing at one or two basins, dishwashing at
a single sink and can also be used for a single shower. Bare wire heating
systems offer rapid heat up times for a near instant supply of hot water.
Please read and understand these instructions before commencing
installation, and leave them with the user when installation is complete.
1. Impo tant safety points
•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 qualified electrician in accordance
with the latest edition of the IEE wiring regulations.
•Only connect the appliance to a power supply that conforms to the specification
stated on the 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.
•Do not use the appliance if there is any possibility of the water supply being frozen.
•Never remove the cover of the appliance without first 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.
•Do not use a supply with incoming water temperatures greater than 600C.

2. Installation
Wall Mounting
• Do not install in areas where there is a risk of water freezing in the heater.
• Do not install the heater where the consequences of a leak could be unusually
severe. (eg above computer equipment)
• When choosing a location for the heater, consider the visibility of any leak that
might arise. This is particularly important when locating in a concealed area such
as a cupboard.
• The heater must be mounted horizontally with the inlet and outlet connections
at the bottom of the heater (see diagram below).

Before attaching the heater to the wall, consider the wiring route to the heater.
The electrical cable can enter the heater through the opening in the back for concealed
cabling. Knock out panels in the top right corner of the back plate and front cover are
available for side entry.
Remove the front cover from the heater by means of the single screw located between
the inlet and outlet fittings.The cover will lift first 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 heater 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, offer the heater to the wall. Ensure the
unit is level and mark the hole locations onto the final mounting surface (see diagram
on previous page).
Ensure there are no hidden cables or pipes before commencement of drilling.
Take the heater away from the mounting surface and drill the holes marked from the
previous step.
Insert wall plugs and offer the heater back up to the mounting surface. Locate the
screws through the unit and into the wall plugs and screw down securely.
Pl mbing
Ensure the following criteria are met for the water supply:
•inimum flow = 2.5L/min
•Pressure in/ ax = 0.1 pa/0.75 pa
•Water resistivity = ≥1300 Ωcm
Suitable for use with pre-heated water e.g. solar heating systems to a maximum
of 600C.
Flush supply pipes to remove any debris before connecting the heater to the
water supply.

ake the plumbing connections as indicated on the front cover of the heater:
• Inlet (cold mains)
• Outlet (hot tap/outlet)
The inlet is the right hand pipe and the outlet the left, when viewed from the front.
The supplied gauze should be installed into the cold inlet side of the plumbing.
All pipework should be adequately earthed.
It is recommended a service valve be fitted on the cold feed to facilitate
future maintenance.
Turn on the cold mains feed and draw water through the heater for several minutes by
opening the hot outlet. Ensure a smooth flow of water from the outlet to confirm all air
is purged from the system and check for leaks on all connections. This step is required
every time the heater has been drained for any reason, such as routine maintenance.

Electrical
Do not commence electrical installation before connecting the heater
to the water s pply and verifying there are no leaks or air gaps.
Electrical installation must be carried out by a qualified electrician in
accordance with the latest edition of the IEE wiring regulations.
Electrical supply should be capable of isolation via a double poled switch.
The heater must be earthed.
Isolate electric and water supply before electrical installation.
Refer to the rating label on the heater to ensure correct specification
of installation.
Connection to the heaters 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’

3. Ope ation
•Once installed and connected to the electrical supply the heater is ready for use.
•Once turned on the heater will automatically power up when it detects a flow of
water through it (min 2.5L/m).
•Due to the nature of instantaneous heaters, water is only heated as it passes
through the tank. Because the maximum power of the heater is fixed there is a
limit to the rate at which hot water can delivered.
Selecting a temperat re
Turn on the heater using the Power On/Off.
On first installation the temperature setting will default to 380C.To adjust this press the
up/down buttons until the desired target temperature is displayed.
To store a frequently used temperature setting, press and hold the “ ” button. This
stores the current temperature and allows it to be recalled at any time by pressing the
“ ” button.
Controls:
1. emory (record/recall temp setting)
2. Increase temp setting
3. Decrease temp setting

Setting the maxim m flow rate
The flow rate is shown on the front display of the heater
in L/min. If the desired temperature cannot be met at
the current flow rate the temperature display will flash
to indicate this. Adjust the flow down using the dial on
the front of the heater until the temperature display
stops flashing.
Once a desired temperature is selected, the heater will manage the power in order to
ensure the temperature is met.The current power usage is displayed by the lines at the
bottom of the display.
Incoming water temperatures can vary depending upon the time of year. For this
reason the maximum flow rate may need adjusting down in order to maintain
a suitable temperature during cold periods.
Overheat Protection
In the unlikely event of a heater malfunction, the unit is fitted with a manual reset
thermal cut-out. 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.
Never remove the cover of the appliance without first isolating it from the
electrical power supply.
Only reset the unit once the cause of the overheat is understood and eliminated.
4. Maintenance
Always disconnect the power before commencing any cleaning or maintenance.
Never open the cover of the heater without first isolating the mains power supply.
To clean the heater 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 qualified/competent person.
