3. Specifications
3.1. Running Principle
The heater-pump AquaPura Split employs
environmental air to heat sanitary water.
The cooling fluid in the heater-pump runs a
thermodynamic cycle that enables the
transference of energy from the environmental air
to the water contained in the storage water
heater.
G-i The air from the environment is forced
through the external unit of the device by a fan.
1-2 When it crosses the evaporator, the cooling
fluid collects the heat from the environmental
heat.
2-3 The compressor aspirates and compresses the
cooling fluid and raises the temperature to a quite
high degree.
3-4 The heat produced by the compressor is
transferred to the condenser that remains in
contact with the sanitary water in the storage
water heater.
4-1 The cooling fluid expands when going through
the expansion valve, and is now ready to collect
the energy present in the environmental air in the
evaporator.

Technical Manual
3.5. Safety and Control Devices
3.5.1. Pressure gauge of high/low
pressure
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.
Should the temperature exceed this value, the
thermostat switches off the support resistance.
Switching on is done manually by qualified staff,
after analyzing the reasons for the switch off.
3.5.3. Temperature Sensor
The temperature sensor has the purpose of
measuring the values of temperature of inlet
external air into the circuit. When these figures
are below or above the limits for running the
equipment, the electric resistance is activated
instead of the heat-pump.
3.5.4. Protection against corrosion
The storage water heater in this equipment can
be of two types: Stainless steel or Enamelled.
Besides being resistant to corrosion, the storage
water heater has in addition a magnesium anode
that should be checked periodically according to
information by the installer.
3.5.5. TPR Safety Valve
The TPR 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 TP valve is place on top of the
storage water heater and the
valve temperature probe must be
completely submerged.
This safety device is already incorporated in your
equipment. The installer must make sure that the
draining of the TPR 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.
WARNING
Incorrect
Correct
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.

Technical Manual
3.5.6. Dielectric Socket
Your AquaPura Split equipment contains two
dielectrics sockets. These sockets prevent electron
exchange between the pipes of water inlet and
outlet and the storage water heater itself. This is
another way to create protection against
corrosion that could take place between these
points (Aand B).
So the installer must tighten the sockets (C) in the
water inlet and outlet (Aand B), before attaching
the piping (D), as demonstrated in the following
sequence:

3.5.7. Expansion tank (1)
The expansion tank is a device whose purpose is
to compensate the increase in water volume due
to temperature rise.
Installing this device is
recommended procedure for a
correct installation of the
equipment.
Installing this device is the
responsibility of the installer.
As a general rule it is installed in
the cold water pipe.
3.5.8. Safety Device (1)
The safety device allows the system to be
protected against anomaly situations: cold water
supply, hot water flowing back, emptying the
storage water heater and high pressure. The valve
is calibrated to activate at 0.7 Mpa.
In order to drain the water in the storage water
heater, you should close the supply valve (4) and
open the discharge valve (5).
The safety valve discharge pipe must be open into
the atmosphere, because the valve may drip
water 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 and not kept in a frozen
environment.
3.5.9. Pressure Throttle Valve (1)
The pressure throttle 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. This valve comes with
a pressure gauge.
__________________________________________________
