•A cooling system, at the top, responsible for transferring heat from ambient air to sanitary
water;
2.2. 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. TRANSPORT
WARNING
The equipment must be carried in an upright position.
The equipment must be raised and lowered with extreme care, to avoid impact
that could damage the material.
Make sure the belts and/or transportation straps do not damage the material.
Always use suitable means to transport the material (pallet lift, forklift, etc.)
The equipment must be transported in its original package to the place of installation.
The packages contain the following information symbols:
Fragile, handle with extreme caution
Keep the package dry
Make sure the arrows are always up
Do not stack packages
4. INSTALLATION
4.1. Safety and Control Devices
4.1.1. 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.
4.1.2. 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.
4.1.3. 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.
4.1.4. Expansion Vessel*
The expansion vessel is a device whose purpose is to compensate for the increase in water volume
due to temperature rise.

Technical Manual
13
MONOBLOC
4.1.5. Safety Group*
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 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. The discharge pipe must be installed upright
away from a cold environment.
4.1.6. Pressure Reducing Valve*
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.
*Parts not supplied by the manufacturer. They must be installed by the installer.
Installing this device is recommended as mandatory for the proper 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.

4.2. Positioning
WARNING
Before starting to assemble the equipment, check the support capacity of the
wall and the material it is made of, considering the weight of the equipment
filled with water.
When placing the equipment in its position, bear in mind possible future interventions.
Make sure that there is at least the following free space around the equipment:
Adjust the levelling feet of the equipment. An inclination angle of up to 1º tilting backwards is
acceptable.
WARNING
If equipment tilts other than back-
wards, this will cause condensates
to deposit in the tank.

4.3. Air Inlet/Outlet Installation
4.3.1. Installation without Ducts
The AquaPura Monobloc equipment must be
in- stalled in a place that is not too heated, and
may be used for dehumidifying and cooling
these rooms (e.g., laundries, cellars, etc).
Distance between the top of the unit and the
ceiling must be no less than 600mm.
If the distance between the unit and the
ceiling is less than 600mm, two elbow-type
joints must be installed as shown in the
following picture.
4.3.2. Installation with Ducts
The AquaPura Monobloc is prepared to install ducts with diameter of 125 mm and 150 mm, in its air
intake and extraction zones:
As the AquaPura Monobloc absorbs heat during its operation, the air flow (inlet/out-
let) must be directed to unheated areas. The equipment will cool the room where it
is placed and so if it is installed in heater rooms, the air flow must be directed to
other rooms and/or the outside.

If ducts are used, directing the air flow to areas that do not require heating, there are some options:
Using Outside Air
If outside air is used, the unit may be
placed either in a heated room or in an
unheated room.
Using Ambient Air
The monobloc unit may also be placed in a heated room, but the air flow must be directed to an
unheated room. Bear in mind that because of air flow, cooling the unheated room can affect the
adjacent heated rooms.

Using Ambient and Outside Air
A branched duct can be used to inflate air into the equipment. So you can get hot air in the summer,
from the outside, and hot air in the winter from an unheated room.
Ducts used to direct the airflow are not included in the equipment, and it is up to the
installer to install them, if necessary, to comply with the manufacturer’s
recommendations.
Diameter of pipes must be of 125 mm or 150mm.
Pipes must not exceed 20 m in length.

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 20 mm
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.

4.5. Thermodynamic Group Access
To access the equipment machine it is necessary to remove the helmet (covering the upper part). If
the installation local has space restrictions that do not allow the helmet to be removed from above
and whose possible access to the machine is only frontal, the following disassembly and assembly
procedure must be followed:
1. Disengage the air insufflation and extraction ducts from the top of the equipment;
2. Unscrew the two fastenings on the front of the equipment, lift the helmet slightly and turn the helmet
180º;
3. Unscrew 2 of the fasteners (on the same side) from the helmet union;
4. With the helmet open, rotate again 180º to remove the helmet from the front.
5. To assemble the helmet, exactly the same steps mentioned must be carried out in reverse.

MONOBLOC
4.6. Condensates
During operation, condensation may occur. These condensates are collected in the drip tray and
drained through a hole at the back of the tray. The installer must connect the condensate hose
supplied by the manufacturer and direct the condensates to the drainage system or drainage siphon.
WARNING
The condensate hose must not be bent/pressed and must be placed where it
best suits the proper flow of condensates.
4.7. Electrical Connections
The thermodynamic equipment must be plugged to the power supply only after filling the storage
water heater. The thermodynamic equipment comes with a mains cable, to be connected to an
earthed monophase voltage (230VAC/50HZ). The connections must comply with the standards of
installation in effect in the territory or country where the thermodynamic equipment has been installed.
The installation includes:
• Bipolar circuit-breaker with connection cable with section equal to or exceeding 2.5 mm
• Protection differential circuit breaker of 30 mA
If the power supply cable is damaged, it must be replaced by the manufacturer, by its custom-
er service, or by staff with similar training.
