• The Aquapoint must be permanently connected to the supply through an
isolating switch with a contact separation of at least 3mm in all poles.
• To protect the Aquapoint, a circuit breaker must be tted with a rating
suitable for the nomi nal current of the Aquapoint.
• The cross sectional area of the connection cable must be appropriate for
the power rating and location of the Aquapoint.
• The connecting cable must be adequately secured.
• This Aquapoint must be earthed at all times.
• Check that the power supply is switched off prior to electrical connection.
• The Aquapoint, its wiring and piping must not be modied in any way.
• Do not remove the cover whilst the Aquapoint is connected to the electricity
supply.
• In case of malfunction isolate the power supply immediately. In case of
leaks also isolate the water supply. Repairs must only be carried out by a
competent person.
• Do not reset the over temperature cut-out until the cause of its operation
has been diagnosed and necessary repairs have been undertaken.
• Do not use the Aquapoint if it is suspected of being frozen. Switch off the
electrical supply if water ceases to ow and do not switch on again until a
competent person has checked that it is safe to do so.
• The heater should be visually inspected regularly. This is particularly
important if its located in a cupboard, roof space or any other concealed
location. If there is any sign of leaks or seepage the Aquapoint should be
isolated from the water supply and switched off from the electrical supply
until a competent person has investigated the cause.
• Do not block or restrict the discharge from any safety valve.
• Do not tamper with any safety valve.
• The Aquapoint must not be subjected to pressure exceeding 6 bar.
• If water discharges from any safety valve switch off the electrical supply to
the Aquapoint, isolate the water supply and contact a competent person
familiar with unvented systems.
• Temperatures in excess of approximately 43°C are perceived as hot,
especially by children, and may cause a feeling of burning. Please consider
using the temperature controls.
• This Aquapoint must not be used by any person (inclu ding children) with
limited physical, sensorial or mental abilities or failing experience and/or
knowledge unless they are supervised by a person responsible for their
safety or have received instruction about how to use the Aquapoint, and
that are aware of the potential hazards.
• Children should be supervised in order to make sure that they do not play with,
use, clean or maintain the Aquapoint.
• In a closed, pressurised system of installation, it is obligatory to install a
safety valve on the inlet pipe with a rated pressure of 0.6 MPa (6 bar),
0.9 MPa (9 bar) or 1.0 MPa (10 bar) (see the label), which prevents the
elevation of pressure in the boiler by more than 0.1 MPa (1 bar) above the
rated pressure.
• Water may drip from the outlet opening of the safety valve, so the outlet
opening should be set to atmospheric pressure.
• The outlet of the safety valve should be installed facing downwards and in
a non-freezing area.
• To ensure proper functioning of the safety valve, the user should perform
regular inspection and maintenance to remove lime scale and make sure
• Do not install a stop valve between the water heater and the safety valve,
because it will impair the pressure protection of the Aquapoint.
• The Aquapoint is equipped with an additional thermal cut-off for protection
in case of failure of the operating thermostat. In this case, however, the
temperature of the water in the heater can reach up to 130°C according to
the safety standards. During the water supply installation, the possibility of
temperature overloads should be taken into account.
• If the Aquapoint is to be disconnected from the power supply, please drain
any water from the heater to prevent freezing.
• Water from the Aquapoint that is installed vertically on the wall can be
drained through the heater’s inlet pipe. For this purpose it is advisable to
install a T- piece with an outlet valve between the inlet pipe and safety
valve.
• Please do not try to x any defects of the Aquapoint on your own.

Installation
• The Aquapoint shall be installed as close as possible to the outlets.
• When installing the Aquapoint in a room with a bathtub or shower, take into account the
requirements dened in IEC Standard 60364-7-701 (VDE 0100, Part 701).
• The Aquapoint has to be tted to the wall using appropriate wall screws with a minimum
diameter of 8mm.
• A wall with a poor load-bearing capacity must be properly reinforced where the Aquapoint
will be installed.
• The AP4 model may only be mounted vertically.
• To facilitate future service interventions, you are advised to install the heater in accordance
with the installation measurements (see Fig. 3 and Fig. 7).
• The water heater connections for the inlet and outlet of water are colour-coded. The inlet
of cold water is marked with blue colour, while the hot water outlet is marked with red
colour.
• The water heater can be connected to the water supply in a closed-circuit pressure system
enables several points of use.
• In a closed, pressurised system (Fig. 4) pressurised mix taps should be used at the outlet
points.
• To ensure safe operation of the heater a safety valve should be installed on the inlet
pipe to prevent elevation of pressure for more than 0.1 MPa (1 bar) above the nominal
pressure.
• The outlet opening on the safety valve must be equipped with an outlet for atmospheric
pressure.
• The heating of water in the Aquapoint causes the pressure in the tank to increase to the
level set by the safety valve. As the water cannot return to the water supply system, this
can result in dripping from the outlet of the safety valve.
• The drip can be piped to the drain by installing a tundish just below the safety valve.
• The drain installed below the safety valve outlet must be piped down vertically and placed
in an environment that is free from the onset of freezing conditions.
• To avoid water dripping from the safety valve, an expansion tank should be installed on the
inlet pipe of the heater with the capacity of at least 5% of the heater volume.
• To ensure proper operation of the safety valve, periodical inspections must be carried out
to remove limescale and make sure the safety valve is not blocked.
• To check the valve, open the outlet of the safety valve by turning the handle or unscrewing
the nut of the valve (depending on the type of the valve).
• The valve is operating properly if the water comes out of the nozzle when the outlet is
open.
Do not t an isolation valve between the Aquapoint and
pressure relief valve
Before connecting it to the power supply, the Aquapoint must
be lled with water
• When lling the heater for the rst time, the tap for the hot water on the mixing tap must be

Functioning of the heater in the SmartEco mode
• This mode is appropriate especially if you have well-established hot water consumption
habits (e.g. showering every day at approximately the same time).
• To start the heater in the SmartEco mode, you rst have to start recording. During the
recording time, the electronic regulator remembers your habits and takes them into
account while heating the water after the recording period has ended.
• The recording takes place for 7 days. The SmartEco mode reduces the consumption of
electrical energy.
• Pressing button will begin the recording of your habits.
• The green control light will ash during the recording period.
• Once recording concludes after 7 days, the recording regime will begin running
automatically.
• The green control light will light up when the heater is functioning in the SmartEco mode.
• By pressing again, you can switch off the recording or the SmartEco function.
• The heater resumes to the basic mode of operation. The water is heated to the set
temperature.
• The SmartEco function can be resumed by pressing button .
• If the regime has already been recorded (if the recording was not interrupted), the regime
will begin running and the green control light will light up.
• If the recording was interrupted, a new 7 day recording period will begin and the green
control light will again begin ashing.
• If the electronic regulator has recorded the regime but the user's hot water consumption
habits have changed, a new recording period must be started. It can be started by holding
button .
If the water in the heater does not reach 65°C for 14 consecutive days, the anti-legionella
function heats the water to 70°C and maintains this temperature for 120 minutes.
