The installation, commissioning and maintenance of these units should be performed by qualified personnel having

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.

1.2. WARNING

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:

² Do not install the appliance near a bedroom window. Avoid locating the appliance in a corner

(increased reverberated noise).

² Install the rubber pads supplied or anti-vibration pads (available as an option) under the appliance.

² Do 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.

2. Attach the outdoor unit to the ground or to its wall bracket.

11.1.4. CONDENSATE EVACUATION

Direct the condensation water towards the wastewater or storm water network.

To ensure effective condensate run-off when connecting to a drain, the pipe should be directed downward towards

the drain at a slope of 2.5 cm/m.

When the installation is completed, test the run-off to ensure that the water runs freely to the drain.

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:

² Stop cocks to isolate the hydraulic circuit during maintenance.

² Manual or automatic bleed valves at the highest point on the water circuit.

² A 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:

² The heat pump maintains its nominal water flow.

² The 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:

² Constant water flow to avoid any major changes in water temperature to the condenser.

² High water flow so that the Heat Pump delivers its heating capacity with a low temperature variance.

² Lowest 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
