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 contact 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 necessary. 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 arrhythmia 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.

English
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 degradation with dangerous consequences for personnel and property. In such an event, the
warranty shall be null and void.
Caution
The unit base shall be arranged as indicated in the manual. There could be a risk of personal injury
or damage to property in the event of the unit being incorrectly supported.
Caution
Unit operation depends on air temperature. Any recycling of air extracted by the fan lowers the air
intake temperature across the exchanger ns and alters the standard operating conditions.
Caution
Do not expose the SysAqua to rejections from chimneys or vents. Fumes charged with soot or
grease as well as acid rejections are likely to clog or damage the condenser irreversibly. This would
cancel the warranty.
Caution
12 SysAqua
9. INSTALLATION
9.1. SITING THE INSTALLATION
The SysAqua must be installed outdoors with sufcient 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. Exchanger fan operation can be
disrupted by strong winds, which can cause de-icing problems and fan malfunctions.
Depending on temperature and outdoor air humidity conditions, water vapour contained in the air can
condense on the nned 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 aid
water run-off and avoid frozen water remaining in the appliance in winter, we recommend that it is mounted
at a height of around 10cm off 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 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, Not supplied).
In orderto contain noise levels,we equip our applianceswith 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 window.
²Do not install the unit in enclosed or conned yards, narrow locations where noise may be reected
on walls
²Avoid 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).
²Electrical and hydraulic connections to the unit must be exible to avoid transmitting vibrations.

9.2. CLEARANCE
When choosing the location for the
SysAqua, take care to leave sufcient
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.
9.3. ATTACHMENT TO THE GROUND
The surface of the oor or structure located under the SysAqua must be at, and with sufcient strength
to withstand the unit's weight with its full liquid load, and occasional presence of maintenance equipment.
For normal applications,
rigidity of the SysAqua
and the positions of
supports allow for an
installation minimizing
vibrations. However, the
installers can use anti-
vibration rubber pads
(supplied in option).
The SysAqua does not require anchoring on the foundations, except in regions exposed to a high earthquake
risk or if the device is installed on a high level on a steel frame.
When tting anti-vibration pads, refer to the manual supplied with the kit.

10. HYDRAULIC LINKS
10.1. MAIN HYDRAULIC CIRCUIT
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:
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.
²A balancing valve on the water outlet pipe in order to control the water ow balance.
²Stop cocks to isolate the hydraulic circuit during maintenance.
²Manual or automatic bleed valves at the highest point on the water circuit.
²Draining connectors at all low points to allow complete circuit draining
²A circulation pump guaranteeing ow and manometric height necessary for the operation of the
SysAqua unit.
²A diaphragm expansion tank tted with a safety and draining valve must be visible.
²A low water pressure sensor to secure the water pump against cavitation if the water pressure in the
circuit decreases.
²The installation of thermometers and pressure gauges on the heat exchanger inlet and outlet to
facilitate day-to-day controls and system maintenance.
²An element ensuring ground continuity of all piping. An unbalance of grounding connection points
can cause corrosion problems due to electrolytic phenomena.
10.2. ANTI-CLOGGING PROTECTION
By default, the SysAqua plate exchanger
would be clogged soon after start-up.
Proper operation of the SysAqua would
be disturbed by the reduced water ow. In
case of insufcient water ow, the plate
exchanger would be damaged IRREVERSIBLY.
The mesh size of the lter must be lower than
800 µm.

English
Before lling the installation, check it and remove any contamination such as sand, stone, welding
chips and other materials likely to damage the SysAqua.
Caution
15SysAqua
For refrigeration only units, the total volume on the level of the primary water circuit must never below:
²application air conditioning
3.5 L/kW refrigeration power
²application process
10 L/kW refrigeration power
10.3. MINIMUM WATER VOLUME REQUIREMENTS
To ensure that the system operates correctly you must use suitably sized and properly routed pipes for the
hydraulic links between the SysAqua and the mains network. Proper operation of the regulation and safety
devices is ensured only when the water volume is sufcient.
10.3.1. SYSAQUA COOLING ONLY VERSION
For reversible units, a water volume equivalent to 12.5L/kW is recommended, which provides for a sufcient
energy reserve to ensure defrosting cycles without discomfort for the end user.
If the total volume of the primary hydraulic circuit does not allow to reach these recommendations, a buffer
tank must be added to the installation to increase the water volume up to the value required.
If the unit runs with a low volume of water (with air treatment plant…) or if it is used for industrial processes,
a buffer tank is compulsory to guarantee sufcient thermal inertia and satisfactory temperature stability.
10.4. MAXIMUM WATER VOLUME REQUIREMENTS
The maximum water volume is limited by the sizing of the unit's expansion tank and/or the expansion tank
present in the facility's hydraulic circuit. Expansion tanks must be sized according to the glycol percentage
in the hydraulic circuit.
Fully rinse all water pipes before nal connection to the SysAqua.
When using an off-the-shelf acid rinsing solution, implement a temporary branching around the SysAqua to
prevent damaging internal components (particularly the plate exchanger, ow switch, pump...).

English
For Heatpump models, if the outdoor temperature is likely to fall below +1°C, provide a system to
prevent the condensates from freezing (e.g. heating cord).
Caution
THE USE OF A GLYCOL-BASED SOLUTION IS THE ONLY EFFECTIVE FROST-PROTECTION MEANS
Caution
Never ll the hydraulic circuit with pure glycol. Maximum glycol concentration is 30%. The water
and glycol mixture must be precisely prepared before lling the hydraulic circuit. If the mixture is
too much concentrated, the hydraulic could be damaged and the unit SysAqua should not perform
normally. In this case, unit guarantee will be cancelled.
Caution
The glycol percentage in the installation's hydraulic circuit must be entered in the ILTC regulation
upon start-up. This parameter setting changes the safety and alarm triggering threshold limits. An
incorrect value may cause malfunctions and a destruction of the unit's heat exchanger.
Caution
Avertissement
It is strongly recommended to post, on the electric box of the unit, glycol type and concentration in
the hydraulic circuit.
16 SysAqua
10.6. FROST PROTECTION
If the SysAqua is exposed to ambient temperatures between 0°C and -18°C, protect the water circuit
against frost.
Draining the water circuit is not recommended for frost protection, for the following reasons:
²The water circuit will rust, which will shorten its lifetime.
²Water will remain at the bottom of the plate exchangers and freezing may cause damage.
The glycol-based water solution must be sufciently concentrated to ensure appropriate protection and
prevent ice from forming at the minimum outdoortemperatures planned for the installation. Take precautions
when using non inert MEG antifreeze solutions (Mono Ethylene Glycol or MPG Mono Propylene Glycol). With
this type of antifreeze solution, corrosion may occur in the presence of oxygen.
Contact glycol resellers to ensure that its characteristics are compatible with environmental directive
applicable on site (this is not under manufacturer responsibility).
The glycol-based solution slightly modies the installation's performance, particularly in terms of load loss:

English
The SysAqua must not run on a network with open loops, likely to cause incidents related to
oxygenation, or with non treated table water.
Caution
If the water circuit is to be drained for a time exceeding one month, the circuit must be fully
charged with nitrogen to prevent any risk of corrosion by differential venting.
Caution
The manufacturer is not liable for recommendations in terms of water treatment (call a specialized
company).
However, this matter has a critical nature, and particular care must be given to ensure that the type
of treatment applied is effective.
The liability of the manufacturer or its representative will not be sought when non treated water
or non compliant quality water is used.
Caution
17SysAqua
10.7. WATER QUALITY
The water must be analyzed; the hydraulic network system installed must include all elements necessary
for water treatment: lters, additives, intermediate exchangers, drain valves, vents, check valves, etc.,
according to the results of the analysis.
Using improperly treated or non treated water in the SysAqua may cause scaling, erosion, corrosion or
algae or sludge deposits in the exchangers. Refer to a specialist skilled in water treatment to determine
any treatment to apply. The manufacturer will not be held liable for damages caused when non treated or
improperly treated water, demineralized water, salty water or sea water are used.
Apply the following guidelines :
²No NH4+ ammonium ions in the water, highly detrimental to copper. <10mg/l
²Cl- chloride ions are detrimental to copper with a risk of puncture by picking corrosion. <10mg/l.
²SO42- sulphate ions may cause perforating corrosion. < 30mg/l.
²No uoride ions (<0.1 mg/l)
²No Fe2+ and Fe3+ ions, particularly in case of dissolved oxygen. Fe< 5mg/l with dissolved oxygen
< 5mg/l. The presence of these ions with dissolved oxygen indicates corrosion of steel parts, likely
to generate corrosion of copper parts under Fe deposits, particularly in the case of multitubular
exchangers.
²Dissolved silica: silica is an acid element of water and may also cause corrosion. Content < 1mg/l.
²Water hardness: TH > 2.8K. Values between 10 and 25 may be recommended. This facilitates scaling
deposits likely to limit copper corrosion. Excess TH values may lead to clogging the pipes.
²TAC<100
²Dissolved oxygen: Prevent any sudden change in the water's oxygenation conditions. Also, avoid
deoxygenating water by sparging inert gas as well as overoxygenating it by pure oxygen sparging.
Disturbing oxygenation conditions destabilizes copper hydroxides and particle salting-out.
²Electrical Resistivity - Conductivity: The higher the resistivity, the slower the corrosion. Values above
3000 ohm/cm are preferred. A neutral environment favours maximum resistivity. For electrical
conductivity, values around 200-600 S/cm can be recommended.
²pH: neutral pH at 20°C (7 < pH < 8)

English
The water inlets and outlets must be connected as described on the labels afxed near the
connections.

When two or three units are connected in parallel, it is recommended that the return circuit connections are
reversed (Tickelman loop system) in order to reduce the pressure loss in each unit’s circuit.
Always check that the manual or automatic air drains are installed at all the high points of the hydraulic
network.
Install a balancing valve on the water outlet pipe to control the water ow balance.
To guarantee proper energy efciency 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.
10.8. HEAT INSULATION
10.9. FILLING THE SYSTEM WITH WATER
It is important to ensure that the mains water supply pressure is sufficient to fill the installation.
Once the installation is complete and after having clean and rinsed out the circuit network, you must ll
the water circuit in accordance with current professional standards until you obtain the service pressure
which will be:
0.5 bar < Service Pressure < 2.5 bars.
When the hydraulic pump option is selected, a
safety valve is mounted (factory assembled) at the
Aqualogic water inlet to prevent from over pressure in
the circuit. The installer has to put a pipe at the safety
valve outlet for water evacuation.
A 3,5 bars safety valve is mounted in the unit when hydraulic options are selected (single or double pump).
