1. INSTALLATION
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
Figure 1 - Minimum margins for
servicing and repairs.
150 mm
100 mm 100 mm
540 mm
H C

500 mm below where the pipes exit the heater to allow access for
maintenance and repair and any necessary future maintenance
operations.
Do not install the heater horizontally with the wall supports
horizontal or over the floor.
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 teflon is used in the thread
of the pipes.
A- The heater MUST be installed with the security fitting that comes
with it. No water system accessory may be placed between the
security fitting and the cold water pipe (stop cock, anti-return, etc).
The security fitting 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 fitting.
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.

SYGMA
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 fittings 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 capabilities
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

7
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

8
SYGMA
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
• Close the tap where water enters the Installation.
• Drain through the safety group using the lever.

temperature indicated on the TFT screen, a percentage value
is displayed. This represents the heating progress towards this
target temperature.
5. OPTIMIZER ENERGY PLUS
This product includes Optimizer Energy Plus Rointe technology to
efficiently manage the energy consumption of the water heater.

15
Optimizer Energy Plus is a technology that bases its operation on
thousands of micropulses being sent to the heating elements to keep
a stable water temperature with a consumption as low as posible.
When the symbol replaces the , then the Optimizer Energy
Plus technology is working.
6. MAINTENANCE
The heater does not need any special maintenance, except an annual
inspection of the magnesium anode. In order to clean it rub with a soft
cloth or damp sponge. Do not use abrasives or detergent.
The electric water heater guarantee is 7 YEARS for the water tank and
2 YEARS for the electronics from the date of purchase. If the water
heater breaks down during this guarantee period the entire appliance
will be replaced. In the Canary Islands, the water tank is guaranteed
for 3 YEARS.
In order to guarantee the life of the water heater, it is a requirement
that the user agrees to an annual inspection of the magnesium anode
to check for erosion. Where erosion is excessive, it should be replaced.
Our guarantee will be applied with the express condition that the
electrical heater has been well installed by QUALIFIED FITTERS and
with the PROTECTIVE SOCKETS which are provided with the appliance
and that there has been an initial inspection of the anode.
Excessive heating by a possible failure of the thermostat is protected
by the safety limiter that cuts the two phases and leaves the heater
without electrical supply. Should this occur, call the Technical
Assistance Department to arrange repair.
IMPORTANT - Never remove the connections cover without first
unplugging the heater from the mains.
