a good knowledge of standards and local regulations, as well as experience of this type of equipment.
This appliance has not been designed for use by persons (including children) with reduced physical, sensorial or
mental faculties or by persons without any experience or knowledge of heating systems, unless they act under the
safety and supervision of a responsible person or have received prior training concerning the use of the appliance.
Children should be supervised to ensure that they do not play with the appliance.
The unit should be handled using lifting and handling equipment appropriate to the unit's size and weight.
Any wiring produced on site must comply with the corresponding national electrical regulations.
Make sure that the power supply and its frequency are adapted to the required electric current of operation, taking
into account specific conditions of the location and the current required for any other appliance connected to the
same circuit.
The unit must be EARTHED to avoid any risks caused by insulation defects.
It is forbidden to start any work on the electrical components if water or high humidity is present on the installation site.

1.3. EQUIPMENT SAFETY DATA
Safety Data R410A
Toxicity Low
In contact with skin Skin contact with the rapidly evaporating liquid may cause tissue chilblains. In case of skin contact
with the liquid, warm the frozen tissue with water and call a doctor. Remove contaminated clothing
and footwear. Wash the clothing prior to re-use.
In contact with eyes Vapours have no effect. Liquid splashes or sprays may cause freeze burns. In these cases rinse your
eyes with running water or with a solution for eye lavages for at least 10 minutes. Immediately
apply to a doctor.
Ingestion In this case, burns may result. Do not attempt to make the patient vomit. If the patient is conscious,
rinse the mouth with water. Call a doctor immediately.
Inhalation In case of inhalation, move the patient to an area with fresh air and provide oxygen if ne-
cessary. Perform artificial respiration if the patient has stopped breathing or lacks air. In
case of cardiac arrest, perform external cardiac massage. Call a doctor immediately.
Further Medical Advice Exposure to high concentrations can be dangerous for individuals with cardiac problems, as the
presence of catecholamines such as adrenalin in the bloodstream may lead to increased arrhyth-
mia and possible cardiac arrest.
Occupational exposure
limits
R410A: Recommended limits: 1,000 ppm v/v 8 hours TWA.
Stability Stable product
Conditions to avoid Increased pressure due to high temperatures may cause the container to explode. Keep out of
the sun and do not expose to a temperature >50°C.
Hazardous reactions Possibility of dangerous reactions in case of fire due to the presence of F and/or CI radicals
General precautions Avoid the inhalation of high concentrations of vapours. The concentration in the atmosphere
shall be kept at the minimum value and anyway below the occupational limits. Since vapours
are heavier than air and they tend to stagnate and to build up in closed areas, any opening for
ventilation shall be made at the lowest level.
Breathing protection In case of doubt about the actual concentration, wear breathing apparatus. It should be self-
contained and approved by the bodies for safety protection.
Storage Preservation Refrigerant containers shall be stored in a cool place, away from fire risk, direct sunlight and all
heat sources, such as radiators. The maximum temperature shall never exceed 50°C in the storage
place.
Protection clothes Wear boots, safety gloves and glasses or masks for facial protection.
Behaviour in case of
leaks or escapes
Never forget to wear protection clothes and brething apparatus. Isolate the source of the leakage,
provided that this operation may be performed in safety conditions. Any small quantity of
refrigerant which may have escaped in its liquid state may evaporate provided that the room is
well ventilated.In case of a large leakage, ventilate the room immediately. Stop the leakage with
sand, earth or any suitable absorbing material. Prevent the liquid refrigerant from flowing into
drains, sewers, foundations or absorbing wells since its vapours may create an asphyxiating
atmosphere.
Disposal The best procedure involves recovery and recycle. If this is not possible, the refrigerant shall be
given to a plant which is well equipped to destroy and neutralise any acid and toxic by-product
which may derive from its disposal.
Combustibility features R410A: Non-inflammable at ambient temperatures and atmospheric pressures.
Containers If they are exposed to the fire, they shall be constantly cooled down by water sprays.
Containers may explode if they are overheated.
Behaviour in case of fire In case of fire wear protection clothes and self-contained breathing apparatus.

5. PRODUCT PRESENTATION
The new family Aqu@Scop Advance Split DCI R410A covers a capacity range from 5 to 14 kW, developed in
4 different sizes.
This system comprises an outdoor unit connected via refrigerating water pipes and electric cables to an indoor
hydronic module that can be fitted to a water circuit to fulfil building room heating and domestic hot water needs.
To satisfy different application, hydronic module has been developed in 2 versions: first one is an heating/cooling
version with auxiliary back-up electrical heater for “stand alone” application; second one is an heating only version
(without electrical heater) that can be fitted in an existing heating system with a 2nd heat generator (for example
a fossil fuel boiler)
The outdoor unit has been optimized for heating application, in order to reach high COP level for radiator, fan coil
and floor heating applications. The feed water temperature of the heat pump to the system can be chosen between
35°C (LT), 45°C and 55°C (MT). Defrost algorithm optimization and blue fin coil on whole range are other 2 key
factors that permits very high performances also at lower outdoor ambient temperature, down to -15°C. The system
is optimized for average climate at +2°C ambient.

11. INSTALLATION
The unit is not designed to withstand weights or stresses from adjacent equipment, pipe work or
constructions. Any foreign weight or stress on the unit structure could lead to a malfunction or a
collapse with dangerous consequences for personnel and property. In such an event, the warranty
shall be null and void.
Unit operation depends on air temperature. Any recycling of air extracted by the fan lowers the air intake
temperature across the exchanger fins and alters the standard operating conditions.
The outdoor unit must be installed outdoors with sufficient surrounding clearance to enable unobstructed air
circulation through the appliance and access for maintenance work.
In the case of the unit being sited in areas exposed to high winds, you must avoid the wind hitting the fan blowing
surface areas directly to avoid any risk of recycling cooled air. Strong wind can disrupt exchanger ventilation and
create de-frosting problems.
The arrows show the direction of air circulation through the appliance. (Refer to Fig. § CLEARANCE).
Depending on temperature and outdoor air humidity conditions, water vapour contained in the air can condense
on the finned heat exchanger and even form ice under low outdoor temperature conditions (around < 5°C). This
condensate water and defrosted water runs off via outlets provided under the exchanger. To facilitate water evacuation
and to avoid ice remaining in the unit in winter conditions, we recommend the use of the shock-absorbing pad
kit to raise the unit to a height of around 10 cm above the ground. In this way, condensate and defrosted water
can run off freely and be absorbed into the ground or channelled to a basin built under the appliance in order to
protect the environment.
In order to contain noise levels, we equip our appliances with quiet fans and encase the technical compartment in
sound-proofed panels. However, noise levels can be reduced even further by following a few installation precautions:
²Do not install the appliance near a bedroom window. Avoid locating the appliance in a corner
(increased reverberated noise).
²Install the rubber pads supplied or anti-vibration pads (available as an option) under the appliance.
²Do not join the concrete slab supporting the appliance to the structure of the dwelling (structure-
borne noise transmission)

11.1.1.3. HOW TO REDUCE NOISE POLLUTION
The unit can be installed in geographic regions where outdoor temperatures below -15° C are rare and of short
duration throughout the year. We advise against installing the unit at heights above 1000m as a decline in
performance is to be expected.

11
11.1.2. CLEARANCE
When choosing the location for the appliance, take care to leave sufficient free clearance on all sides to ensure
easy access for maintenance work. The minimum free clearance dimensions indicated must be observed to ensure
both proper system operation and allow access for maintenance and cleaning.
11.1.3. ATTACHMENT TO THE GROUND
The unit location dimensions are indicated on the figure below. A slope of 1 cm/m should be created to assist
rainwater drainage.
Vibration dampers must be fitted during installation to overcome any risks of vibration being transmitted due to
direct contact with a rigid support surface.
The appliance should be mounted 10 cm above the ground on a level, rigid and preferably concrete
surface.

11.2. INDOOR UNIT
11.2.1. SITING THE INSTALLATION
The unit has been designed for indoor applications and must be sited in a location protected from bad weather
and without any risk of freezing during winter months. The premises must be clean, dry and properly ventilated.
The appliance must be sited with its anti-vibration pads on a level, solid and preferably masonry, floor.
If there is a possibility of the indoor temperature falling below 1°C, you must take every precaution to provide anti-
freeze protection for the hydraulic circuit (addition of mono-propylene glycol)
When choosing the location for the appliance, take care to leave sufficient free clearance all around to ensure
easy access for maintenance work. The minimum free clearance dimensions indicated must be observed to ensure
both proper system operation and allow access for maintenance and cleaning.

12. HYDRAULIC LINKS
When choosing and installing water pipes, you must consult and observe all current local standards, regulations
and instructions.
12.1. GENERAL RECOMMENDATIONS
You must design the pipe network with the minimum number of bends and keep the number of changes in height
to the strict minimum. This will reduce installation costs and ensure optimum system performance. The pipe network
must include:
²Stop cocks to isolate the hydraulic circuit during maintenance.
²Manual or automatic bleed valves at the highest point on the water circuit.
²A suitable system for maintaining water pressure in the circuit (all Aqu@Scop Advance Split DCI
models have an internal expansion tank).

14
When installing Aqu@Scop Advance Split DCI appliances in existing water circuits, a sludge trap and a removable
mesh filter should be installed upstream of the appliance.
To avoid all risks of foreign object ingress and to preserve the performance of the machine, IT IS
NECESSARY TO INSTALL THE WATER FILTER ACCESSORY at the inlet of the machine.
To ensure that the system operates correctly you must use suitably sized and properly routed pipes for the hydraulic
links between the Heat pump and the mains network.
The volume of water in the installation must be sufficient to avoid short defrosting cycles and to operate without
any loss of comfort. To ensure the Aqu@Scop Advance Split DCI functions efficiently, available installation
water volume must be:
12.1.1. EXPANSION TANK
Aqu@Scop Advance Split DCI units are equipped with an expansion tank with the following volumes and pre-
pressurisation pressures:
It is important to make sure that the pressure in the water supply
system is sufficient to enable the installation to be filled correctly.
It is necessary to ensure that the expansion tank is sufficiently
large for the installation.
1. Check of the required volume
2. Adjustment of the pressurisation pressure
When water circulation through heat emitters can be interrupted (thermostatic radiator valves closed) or the heating
supply halted, you must ensure that:
²The heat pump maintains its nominal water flow.
²The heat pump works in a loop with a useful volume that complies with the required minima.
The use of a 3-speed circulation pump enables water flow through the appliance to be adapted to pressure losses
in the system. Refer to water flow graph.

Layout 3: radiator application or underfloor heating application with individual room regulation
This layout is also recommended for heating installations with wide operating water flow variations (radiator
thermostatic valves present in the system). Minimum system volume is guaranteed by a mixing tank (10). Take care
when calculating the volume of water in the installation and only take account of 50% of the mixing tank's volume.
Example: For a useful volume of 100 litres the actual mixing tank volume will be 200 litres.
The flow regulating valve (10) is used to balance the flow in heating mode and domestic hot water production
mode to always ensure optimum Aqu@Scop Advance Split DCI operation.

12.2.2. AQU@SCOP ADVANCE SPLIT DCI WITH BOILER
To ensure optimum operation, the Heat Pump must always be connected to the radiator or under-floor heating
return water pipe via a secondary circuit to avoid affecting the water flow in the existing heating network. This type
of layout meets the following three criteria:
²Constant water flow to avoid any major changes in water temperature to the condenser.
²High water flow so that the Heat Pump delivers its heating capacity with a low temperature variance.
²Lowest possible water temperature even when the boiler is in use, in order to improve the Heat Pump's
COP and increase the number of operating hours.
We recommend the fitting of a zone valve to avoid heat losses via the boiler when the Heat Pump is working on
its own.
All system devices should be of a suitable size to limit pressure losses
Water flow within the heating circuit is normally driven by the circulation pump already present in the installation
(recommended solution) or by the Heat Pump's circulation pump. In this case, you must ensure that the circulation
pump generates sufficient water pressure.
The heat pump is equipped with a 10 litre expansion tank. Ensure that the size is adequate for both the volume of
water in the installation and its operating water temperature.
COMMENT: WALL-MOUNTED GAS-FIRED BOILER with domestic hot water production and a
single circulation pump used for both heating and domestic hot water:
DO NOT FIT A ZONE VALVE
