1. INTRODUCTION
1.1. Accessories
The electric water heater, or boiler by accumulation under
pressure, is provided with basic elements for its installation,
such as:
• Insulating sockets.
• Safety valve.
These accessories are included within the packaging.
1.2. Placement
In order to fix the heater to the wall, you will have to use suitable
rawlplugs, screws, or other fittings to support the weight of the
heater when it is full.
1.3. Location
It is essential that the heater
is situated as near as possible
to the place where hot water
is required. In this way, water
temperature loss in the
pipework can be avoided.
Leave a minimum space of 500
mm below where the pipes
exit the heater to allow access
for maintenance and repair
and any necessary future
maintenance operations
150 mm
100 mm 100 mm
540 mm

D Series with DELTA Ultimate technology
Do not install the heater horizontally with the wall supports
horizontal or over the oor.
1.4. Water system installation
WARNING TO THE INSTALLER: the insulating sockets provided
with the heater must be placed on the entrance and exit pipes to
eliminate the risk of galvanic pairs as teon is used in the thread
of the pipes.
A- The heater MUST be installed with the security tting that comes
with it. No water system accessory may be placed between the
security tting and the cold water pipe (stop cock, anti-return, etc).
The security tting drainage outlet MUST be connected to a
water drainage pipe that has to have a diameter that is at least
equal to the diameter of the pipe connected to the boiler, with
a continuous inclination, open to the atmosphere and with a
minimum distance of 20 mm. During the warm-up time the water
expands producing a drip (approximately 3% of its capacity during
each heating cycle). This is not a cause for concern because it
is a normal phenomenon. Please ensure that the water drainage
conduct pipe is protected from frost. To drain the heater, lift the
handle of the security tting. It is also necessary for this handle to
be periodically checked to avoid blockage by, for example: mud
deposits, limescale deposits, etc.
B- When the pressure of the network is higher than 5 bars, it is
necessary to install a pressure reducer as near as possible to
the meter.

1.5. Electrical installation
The appliance requires a single-phase 230 V supply. It is
necessary to check carefully that the supply voltage agrees
with the required voltage of the appliance. The heater does not
need installation requirements outside the norm, therefore it is
suitable for installation in accordance with the Electrotechnical
Low Voltage Regulations.
The power supply will have to be wired through a omnipolar
interrupter, circuit breaker or contactor. The installation must
be protected with fuses of a rating that corresponds with the
intensity absorbed. The socket must be placed in such a way
that when the heater is installed the plug is accessible. An
earth connection must be included throughout the electrical
installation. In order to ensure this connection the plug comes
provided with the relevant contact. It is important that the style
of any other plug used is the same type as the one provided
with the appliance.
The electrical system of the premises or house must be
checked to ensure that it is equipped with an “EARTH” wire.
This appliance complies with the regulations on radio-electric
disturbances and interferences.
NOTE: All maintenance and replacement of the ttings is
prohibited (including the feed cable), unless it is authorised by
the Technical Assistance Department.

1.6. Safety
This water heater can be used by children aged 8 years and above
and persons with reduced physical, sensory or mental capabili-
ties or lack of experience and knowledge if they are supervised or
have been given instruction concerning use of the appliance in a
safe way and understand the hazards involved. Cleaning and user
maintenance shall not be made by children without supervision.
Children must be supervised at all times to ensure that they do not
play with the product.
2. USE
2.1. Operation
Filling. Once the heater has been installed, open the stop cock.
Then open the hot water taps. When the water begins to come out
of them the heater is full. Close the taps and check thoroughly that
there are no leaks in the installation. Do not connect the heater to
the mains supply before ensuring that it is full of water.
Electrical connection. Plug in the heater, switch on and leave the
appliance connected to the electricity supply. Once a certain
amount of hot water has been used, the thermostat switches the
heating element back on.
Draining. In prolonged periods without use, and if there is risk of
frosts in the premises where it is installed, the heater must be
drained. It is possible to do this using the safety valve.
In all cases:
• Cut the current

10
• Close the tap where water enters the Installation.
• Drain through the safety group using the lever.
