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.

SEE APPENDIX
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. § Floor location).
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 assist drainage and
to prevent frozen water remaining in the appliance in winter, we recommend that the unit is installed at a height
of around 10cm off the ground and placed on plastic blocks or other suitable supports (damper feet proposed as
an accessory). 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 areas where outdoor temperatures fall below 1°C, the system can be equipped with a condensate anti-freeze
protection system (e.g. a heated pipe sheath).
To reduce the noise level, our machines are equipped with quiet fans and a soundproofed compressor.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.
²Use flexible hoses (available as options) for connections between the appliance and the mains water
network.
²Do not join the concrete slab supporting the appliance to the structure of the dwelling (structure-
borne noise transmission)

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
²You 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:
²A vibration elimination system (e.g.: link hoses available as an accessory) on all pipes connected to
the appliance in order to reduce vibrations and noise transmitted to the building fabric.
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 DCI models
have an internal expansion tank).
²The installation of thermometers and pressure gauges on the heat exchanger inlet and outlet to
facilitate day-to-day controls and system maintenance.
When installing Aqu@Scop Advance 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 (supplied) 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 DCI functions efficiently, available installation water
volume must be:
12.1.1. EXPANSION TANK
Aqu@Scop Advance DCI units are equipped with an expansion tank with the following volumes and pre-
pressurisation pressures:
6 12 16
Volume l 3 5
Pre-pressurisation pressure bar 0.5 2
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
6 12 16
available water volume l 140 190 250
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. Pump delivered set to position MV for model 6 and to GV for models 12 and 16). Refer to water
flow graph.

This layout is recommended for heating installations with wide operating water flow variations (radiator thermostatic
valves present in the system). We strongly recommend including the buffer tank (2) as it guarantees that the heating
loop capacity is higher than the minimum volume when the maximum number of thermostatic valves are closed.
The flow regulating valve (11) is used to balance the flow in heating mode and domestic hot water production
mode to always ensure optimum Aqu@Scop Advance DCI operation.

12.3. ANTI-FREEZE PROTECTION
We recommend that the installation is protected against freezing by adding anti-freeze.
The chart below indicates the concentration of anti-freeze to be used relative to the minimum outdoor temperature
reached.
Using untreated or inadequately treated water in this appliance can lead to a build-up of limescale,
algae or sludge deposits and cause corrosion and erosion. As the manufacturer is not aware of
the components used in the hydraulic network, or of the quality of water used, the installer or the
owner should contact a specialised water treatment company. This issue is particularly important
and every care should be taken to ensure that circuit water is properly treated in order to avoid
problems associated with incorrect water distribution. A clogged water network will systematically
lead to premature wear of the appliance's components.
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 (11) is used to balance the flow in heating mode and domestic hot water production
mode to always ensure optimum Aqu@Scop Advance DCI operation.

12.5. CONNECTION TO THE CENTRAL HEATING LOOP
You must check water tightness and the cleanliness of the installation before connecting the Aqu@Scop Advance DCI.
For the Aqu@Scop Advance DCI's WATER INLET and OUTLET connections, you must install manual stop
cocks with the same diameter as the main pipe work. This will enable maintenance work to be carried out on the
Aqu@Scop Advance DCI without having to bleed the entire system.
A link valve with pressure tap kit is available.
The Aqu@Scop Advance DCI must be protected by a water filter. Connect this subassembly to the water inlet
of the unit, taking care to maintain the strainer of the water filter downwards. A sludge trap should be fitted in the
event of high sludge build-ups.
WARNING!
Take care not to damage the hydraulic pipe links by applying too much tightening pressure.
Use a second wrench to compensate for the tightening torque.
You should always use a counter-wrench for tightening valves.
12.6. HEAT INSULATION
To guarantee proper energy efficiency and compliance with current standards, water pipes passing through
uninhabited zones should be properly lagged to retain heat.
To achieve correct insulation with conductivity of 0.04 W/mK, lag the pipes with insulating material with a radial
thickness between 25mm and 30 mm.
12.7. FILLING THE SYSTEM WITH WATER
All installation works must be completed and the system cleaned and drained, before filling the water circuit in
accordance with current best practices. The system should be filled to obtain a service pressure not exceeding 2.5
bars.
The water supply should come either from the mains network or from the Heat Pump or from any other point on
the installation.
Check that the automatic bleed valve operates correctly.
You must completely bleed the circuit of all air to ensure efficient operation.
Close the inlet water valve once the hydraulic circuit is filled correctly.
12.8. WATER FLOW CONTROLLER
A paddle type water flow controller is fitted to the water circuit connected to the condenser. The purpose of this
safety component is to ensure that a minimum water flow is established before the unit is started up.
The appliance is equipped with a set of safety devices including a safety valve set at 3 bars and a manual pressure
relief valve.

14. ELECTRICAL CONNECTIONS
WARNING
Before carrying out any work on the equipment,
make sure that the electrical power supply is
disconnected and that there is no possibility
of the unit being started inadvertently.
Non-compliance with the above instructions
can lead to injury or death by electrocution.
The electrical installation must be performed by a fully qualified electrician, and in accordance with local electrical
standards and the wiring diagram corresponding to the unit model.
Any modification performed without our prior authorisation may result in the unit’s warranty being declared null
and void.
The power supply cable section must be sufficient to provide the appropriate voltage to the unit’s power supply
terminals, both at start-up and under full load operating conditions.
The power supply cable shall be selected in accordance with the following criteria:
1. Power supply cable length.
2. Maximum unit starting current draw – the cables shall supply the appropriate voltage to the unit
terminals for starting.
3. Power supply cables’ installation mode.
4. Cables’ capacity to transport the total system current draw.
Short circuit protection shall be provided. This protection shall comprise fuses or circuit breakers with high breaking
capacity, mounted on the distribution board.
If the local control includes a remote ambient terminal, it shall be connected with shielded cable and shall not
pass through the same conduits as the power supply cables as the voltages induced may create reliability faults in
the unit’s operation.
WARNING!
On-site wiring must be performed in accordance with the wiring diagram present in the appliance's
electrical connection box.
Mains power supply cables to the appliance must have copper conducting cores and be sized in
compliance with currently applicable IEC standards.
The installer must make sure that the installed power, the amperage and type of the protections and
the cross-section of the cables are sufficient to avoid an overload, and tripping of the installation
to protection mode.
The appliance must be grounded via a terminal block located inside the electrical connection box.
The power supply must not fluctuate by more than 10 %.
