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.
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.
Removing and Mounting the Bracket
• Use a at headed screwdriver or similar, place it into the lug on the bracket (between
the inlet/outlet connections, see diagram 1) and then gently lever the bracket away
from the heater.
• To remove the bracket fully from the unit pull down at the bottom of the bracket.
• When retting the unit to the bracket reverse the process.
• Before attaching the bracket to the wall, consider the wiring route to the heater. The
bracket on the heater has an additional knock out section to allow the wire to exit
from either the left, right or top of the bracket depending on wiring requirement.
Always ensure there are no hidden cables or pipes before commencement of
drilling.

Diagram 1
• The unit can be installed with the inlet and outlet at the top or at the bottom. Ensure
the bracket orientation corresponds with the unit. When installed with the inlet and
outlet at the bottom of the heater the electronic temperature display will rotate
automatically.
• 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 (see Diagram 1).
• Ret the unit to the bracket to complete mounting.
Cable defaults out of the right hand side when viewed from the front and installed with the inlet/
outlet at the top of the unit. Supplied pre knocked out but can be changed if desired.

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 qualied 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 specications of the heater as stated on the
rating label and ‘Specication’ 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
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.
• Turn on the heater using the on/ o touch screen (see diagram 3). It will automatically
begin heating when it detects a ow of water through it.
• On rst installation the heater requires an initial 12 seconds (approx) of continuous
water ow through the unit to start heating.
• When the water ow is turned on using the outlet/ tap, the heater will display the
current water temperature. The electronic temperature display will only operate
whilst water is owing through the heater.
• Whilst water is owing through the heater, the target temperature can be adjusted
using the left / right hand touch screen adjustments. After a second or two the heater
will go back to displaying the current water temperature and the new setting is
stored.

Diagram 3

• Once the target temperature is set the heater will aim to reach it and will never
exceed it.
• 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.
• If there is a power interruption the heater will recall the last selected temperature.
When power is restored the heater must be turned back on using the bottom on/
o touch screen. Following this, it will again require 12 seconds (approximately) of
continuous water ow through the unit to start heating.

• Press down on the ribbed area of the cover and move towards the wall.
• Apply pressure to the rear of the cover until the front lifts.
• Remove the cover by pulling it forwards.
• Adjust the screw to the desired setting. Turn anticlockwise for maximum water ow.
Turn clockwise to reduce the water ow.
Adjusting Water Flow Rate
Diagram 4
A ow restrictor is supplied and must be tted to the outlet/tap attached to this heater.
This is the best way to control the performance of this product and so adjustment of
the ow rate should not be necessary except in areas with notably high incoming water
pressures.

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 qualied/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.
