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.
•The operating principle of this equipment is directly linked to high temperatures and
pressures, so all processes that involve contact with the equipment must be prepared with
care to avoid risks of burns and material projection.
•The heating of other fluids than drinking water is not allowed.
Every process that the supplier believes to be conducive to harmful danger
and/or material damage will be signalled with a danger sign.
To better characterize the danger, the symbol will be followed by one of these
words:
•DANGER: when there is the possibility of harm to the operator and/or
people in the vicinity of the equipment.
•WARNING: when there is the possibility of material damage to the
equipment and/or attached materials.

3. Specifications
3.1. Running Principle
1. The cooling fluid (R134a) is compressed in the high efficient compressor, raising its pressure
and temperature;
2. In the condenser (not in direct contact with the water), the heat energy in the cooling fluid is
transmitted to the water in the water storage heater;
3. The condensate fluid (high pressure) runs from the expansion valve which is responsible for
easing the its pressure;
4. The fluid absorbs heat energy from the environment by flowing through the evaporator with
the help of a fan;
The R134a is a HFC fluid, thus not harmful to the ozone layer. It has great
chemical and thermal stability, low toxicity, non-inflammable, and is compatible
with most materials.

3.5. Safety and Control Devices
3.5.1. High/Low Pressure Switch
In case of running outside the range of pressures recommended and defined by the supplier, the
equipment will switch off and indicate error in the electronic panel.
3.5.2. Safety Thermostat
The safety thermostat is set by the supplier to ensure that the water temperature in the storage water
heater does not exceed the standard value. If the temperature exceeds this value, the thermostat
switches off the backup electrical heater. Switching on is done manually by qualified staff, after
analysing the reasons for the switch off.
3.5.3. Temperature Probe
The purpose of the temperature probe is to measure the temperature values of water in the storage
water heater in order to control the system.
3.5.4. Protection against Corrosion (if applicable)
Besides being resistant to corrosion (stainless steel), the storage water heater has in addition a
magnesium anode that should be checked periodically according to information by the installer.
3.5.5. PT Safety Valve
The PT valve (combined safety valve of temperature and pressure) is placed on top of the storage
water heater and its purpose is to limit the pressure/temperature of the water inside the storage water
heater. This valve has been previously calibrated to prevent the water temperature from exceeding
99º C and pressure from exceeding 10 bar. If any of these figures is reached, the valve will open and
release water until the temperature and pressure inside the storage water heater are within the
calibrated range.
The PT valve (combined safety valve of temperature and pressure) is placed on top
of the storage water heater and its purpose is to limit the pressure/temperature of the
water inside the storage water heater. This valve has been previously calibrated to
prevent the water temperature from exceeding 99ºC and pressure from exceeding 10
bar. If any of these figures is reached, the valve will open and release water until the
temperature and pressure inside the storage water heater are within the calibrated
range.
This safety device is already incorporated in your equipment. The installer must make sure that the
draining of the PT valve is done according to the standards.
Remember that:
•In the horizontal installation, the water outlet nozzle must not be turned downside up to prevent
the accumulation of waste in the device.
AVISO

Technical Manual

AQUAPURA SPLIT
•Discharge must be done so that the normal running of the valve is not stopped and without
risk for people or to materials.
•Discharge must be visible and into a suitable collection pipe.
•Discharge must be done into a suitable container
3.5.6. Expansion Vessel (1)
The expansion vessel is a device whose purpose is to compensate for the increase in water volume
due to temperature rise.
The placement of this device is a recommended procedure for a correct installation
of the equipment.
Installation of this device is the responsibility of the installer.
As a general rule, it is installed in the cold water pipe.
3.5.7. Safety Group (1)
The safety device allows the system to be protected against anomaly situations: cold water supply,
hot water flowing back, emptying of the storage water heater and high pressure. The valve is
calibrated to activate at 0.7 MPa).
To drain the water in the storage water heater, you should close the supply valve and open the
discharge valve.
The safety valve discharge pipe must beopen into the atmosphere, because the valve may dripwater
or even discharge water.
The safety valve must be opened regularly to remove impurities and check that it is not blocked. The
discharge pipe must be installed in a vertical position. The discharge pipe must be installed upright
away from a cold environment.
3.5.8. Pressure Reducing Valve (1)
The pressure reducing valve must always be installed upstream from the safety device, and ready to
activate in situations when the pressure in the circuit exceeds 3 bar (0,3MPa). This valve comes with
a pressure gauge.
__________________________________________________
(1) Parts not supplied by the manufacturer. They must be installed by the installer.

WARNING
It is necessary to install a safety device at the cold water inlet of the appliance.
The safety device must be in compliance with the standard EN 1487:2002,
maximum pressure 7 bar (0.7 MPa) Water must not be stopped from flowing
from the safety device to the deposit by any sort of accessory.
The safety device must be connected with piping whose diameter is not less
than the cold water inlet coupling. The discharge must be connected to a
sewage siphon or, if this is not possible, elevated to a distance of at least 20mm
from the pavement to allow visual inspection;
To prevent high pressure from main water supply, install a pressure reduction
valve set to 3 bar (0.3 MPa).
The Manufacture is not responsible for damage related to not following these
recommendations/ warnings.

•Shelter the equipment in places susceptible to ice formation
•Choose the position closest to the main points of use;
•Always insulate the pipes;
•The temperature around the equipment must not exceed 40 °C;
•The water heater should never be placed outside, also avoiding exposure to sunlight.
•Make sure that the support surface is sufficient to accommodate the weight of the water-filled
water heater.
•In order to guarantee accessibility to the equipment for maintenance or any other need, the
schematic cluttering distances must be respected:
