not respected.
If you meet a problem, please call the Technical Department of your area.
If possible, assemble the compulsory or optional accessories before placing the appliance on its nal location
(see instructions provided with each accessory).
In order to become fully familiar with the appliance, we suggest to read also our Technical Instructions.
The information contained in these Instructions are subject to modication without advance notice.
Hazardous reactionsPossibility of dangerous reactions in case of fire due to the presence of F and/or CI radicals.
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.
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.
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.
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.
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.
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.
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.
In case of doubt about the actual concentration, wear breathing apparatus. It should be self-contained
and approved by the bodies for safety protection.
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.
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.
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.
Containers
Behaviour in case of fireIn case of fire wear protection clothes and self-contained breathing apparatus.
If they are exposed to the fire, they shall be constantly cooled down by water sprays.
Containers may explode if they are overheated.

9. INSTALLATION
11SysAqua
Caution
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.
9.1. SITING THE INSTALLATION
The SysAqua must be installed outdoors with sufcient surrounding clearance to enable unobstructed air
circulation through the appliance and access for maintenance work.
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.
9.1.1. PREVAILING WIND
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.
English
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.
9.1.2. CONDENSATE WATER MANAGEMENT IN HEATING MODE
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, these 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 antifreeze protection system (e.g. a heated pipe sheath, Not supplied).
9.1.3. HOW TO REDUCE NOISE POLLUTION
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 window.² Do not install the unit in enclosed or conned yards, narrow locations where noise may be reected
on walls.
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).
² Electrical 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 sufcient
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.
Caution
When several SysAqua units are installed, ensure proper clearance is implemented around the
condensers specic to each machine.
9.3. ATTACHMENT TO THE GROUND
The surface of the oor or structure located under the SysAqua must be at, and with sufcient strength
to withstand the unit's weight with its full liquid load, and occasional presence of maintenance equipment.
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.

10. HYDRAULIC LINKS
Caution
When choosing and installing water pipes, you must consult and observe all current local standards,
regulations and instructions.
10.1. MAIN HYDRAULIC CIRCUIT
Caution
The mains hydraulic circuit will provide a constant water ow on the refrigerating uid/water plate
exchanger and in case of load variation.
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 A vibration elimination system (e.g.: link hoses) on all pipes connected to the appliance in order to
reduce vibrations and noise transmitted to the building fabric.
² A balancing valve on the water outlet pipe in order to adjust the water ow.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 Draining connectors at all low points to allow complete circuit draining.
English
² A circulation pump guaranteeing ow necessary for the operation of the SysAqua unit.² A diaphragm expansion tank tted with a safety and draining valve must be visible.² A low water pressure sensor to secure the water pump against cavitation if the water pressure in the
circuit decreases.
² The installation of thermometers and pressure gauges on the heat exchanger inlet and outlet to
facilitate day-to-day controls and system maintenance.
² An element ensuring ground continuity of all piping. An unbalance of grounding connection points
can cause corrosion electrolytic.
Caution
The expansion tank must be dimensioned to be able to absorb an expansion corresponding to 2%
total volume of water contained in the installation (exchanger, piping, installations and buffer tank,
if present).
Caution
THE WARRANTY DOES NOT COVER DAMAGE DUE TO CORROSION RESULTING FROM ELECTROLYTIC

10.2. ANTI-CLOGGING PROTECTION
Caution
To avoid any risk of foreign bodies entering the appliance and to guarantee operating performance,
IT IS IMPERATIVE TO INSTALL WATER FILTER on the SysAqua inlet pipe.
Failing that, SysAqua's heat plate exchanger would clog up soon after being commissioned. Proper
operation of the SysAqua would be disturbed
by a reduced water ow or the partial
blockage of certain heat plates. The heat plate
exchanger could be IRREVERSIBLY damaged if the water ow were not sufciently high.
A link smaller than or equal to 800µm is
recommended
Caution
THE MANUFACTURER'S WARRANTY IS VOID IF THE FILTER SUPPLIED WITH
THE SYSAQUA IS NOT INSTALLED TO PROTECT THE APPLIANCE

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 sufcient.
For refrigeration only units, the total volume on the level of the primary water circuit must never below:
² application air conditioning
3.5 L/kW refrigeration power
² application process
10 L/kW refrigeration power
For reversible units, a water volume equal to 12.5 L/kW is recommended, so that energy reserves are full
enough to ensure the defrosting cycle without any 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 sufcient 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.
The expansion tank should be installed at the pump suction, and the pressure inside will be adjusted by
taking into account the whole hydraulic circuit.
The volume of the expansion tanks selected with Single pump and double pump options are :

10.5. RINSING THE CIRCUIT
Caution
Before lling the installation, check it and remove any contamination such as sand, stone, welding
chips and other materials likely to damage the SysAqua.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
If the SysAqua is exposed to ambient temperatures between 1°C and -18°C, protect the water circuit
against frost.
Caution
THE USE OF A GLYCOL-BASED SOLUTION IS THE ONLY EFFECTIVE FROST-PROTECTION MEANS
The glycol-based water solution must be sufciently concentrated to ensure appropriate protection and
prevent ice from forming at the minimum outdoor temperatures 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).
Caution
The glycol percentage in the installation's hydraulic circuit must be entered in the 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.
Avertissement
It is strongly recommended to post, on the electric box of the unit, glycol type and concentration in
the hydraulic circuit.
English
The glycol-based solution slightly modies the installation's performance, particularly in terms of load loss:
5 > T > 00 > T > -5-5 > T > -10-10 > T > -30
10203045
1.0701.1601.2351.368
1.0151.0501.0851.169
0.9950.9850.9700.949

1.0051.0301.0671.162
0.9910.9770.9450.894
Example for a solution with 20% Mono Ethylene Glycol:
² Increase the pressure drop : with glycol = 1.160 x without glycol² Increase the owrate : with glycol = 1.050 x without glycol² Decrease the capacity : with glycol = 0.985 x without glycol
Draining the water circuit is not recommended for frost protection, for the following reasons:
² The water circuit will rust, which will shorten its lifetime.² Water will remain at the bottom of the plate exchangers and freezing may cause damage.
Caution
Never ll the hydraulic circuit with pure glycol. Maximum glycol concentration is 45%. 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
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).

16 SysAqua
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.
Caution
The SysAqua must not run on a network with open loops, likely to cause incidents related to
oxygenation, or with non treated table water.
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 :
² No NH
+
ammonium ions in the water, highly detrimental to copper. <10mg/l
4
² Cl- chloride ions are detrimental to copper with a risk of puncture by picking corrosion. <10mg/l.
2-
² SO
sulphate ions may cause perforating corrosion. < 30mg/l.
4
² No uoride ions (<0.1 mg/l)² No 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.
² Dissolved silica: silica is an acid element of water and may also cause corrosion. Content < 1mg/l.² Water hardness: Values between 10°fH and 25°fH may be recommended. This facilitates scaling
deposits likely to limit copper corrosion. Excess TH values may lead to clogging the pipes.
² TAC<100² Dissolved 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.
² Electrical 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.
² pH: neutral pH at 20°C (7 < pH < 8)
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.

17SysAqua
10.8. HEAT INSULATION
To guarantee proper energy efciency 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.
10.9. FILLING THE SYSTEM WITH WATER
Caution
FILLING OR DRAINING THE WATER CIRCUIT MUST BE PERFORMED BY SKILLED PERSONS USING THE
APPROPRIATE DEVICES ON THE EXTERNAL HYDRAULIC CIRCUIT BY THE INSTALLER.
It is important to ensure that the mains water supply pressure is sufcient to ll 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 bar
A 3.5 bar safety valve is mounted in the unit when hydraulic options are selected (single or double pump).
English
Always check that the manual or automatic air drains are installed at all the high points of the hydraulic
network.
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.
UNIT 1
VR
VV
UNIT 2
VR
Install a balancing valve on the output pipe to adjust the water ow.
Caution
The water inlets and outlets must be connected as described on the labels afxed near the
connections.
VV
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.

17.3. MAINTENANCE PROCEDURES
17.3.1. REFRIGERANT CIRCUIT
This equipment must be submitted to sealing checks minimum once per year, by a professional authorized
to perform such an operation. Refer to national requirements for the frequency of these checks.
Caution
Never use the compressor as a vacuum pump to drain the installation.
17.3.1.1. REFRIGERATING FLUID CHARGE
Run the unit in refrigerating mode to determine whether the group's charge is correct by checking actual
sub-refrigeration.
17.3.1.2. COMPRESSOR OIL
Oil for refrigeration equipment is light and transparent. It maintains its colour for a long operating period.
As a refrigeration system designed and installed properly will run without problem, the compressor oil does
not require replacement, even after a long operating period.
Blackened oil has been exposed to impurities in the refrigeration piping system, or excess temperatures
on the compressor backow side, which inevitably degrades oil quality. Blackening oil or degradation of its
qualities may also be caused by humidity in the system. Change the oil when its colour changes or when it
is degraded.
In this case, before restarting the unit, the refrigeration circuit must be emptied.
Caution
Compressors use polyester oil. During maintenance interventions on the compressor, or if the
refrigeration circuit has to be opened in any point, do not forget that this type of oil is highly
hygroscopic, and avoid exposing it to the atmosphere during long periods, which would require to
change the oil.
Warning
Protect the SysAqua frame so as to get back oil that could ow out accidentally.
17.3.1.3. FILTER DRIER
Refrigeration circuits are tted with lters drier.
The uid indicator is used to check the refrigeration ow and humidity rate of the refrigerating uid. The
presence of bubbles indicates that the lter drier is clogged or the charge insufcient.
If you notice that air bubbles are still there even after the lter has been replaced, this means the device
has lost part of its cooling product in one or several places, which will need to be detected and repaired.
The glass window contains a colour indicator. Comparing the indicator colour with the scale present on the
glass window allows to calculate the humidity rate of the refrigerating uid. If excessive, change the lter,
run the system for one day, then check the humidity rate again.
A humidity rate within the preset limits requires no further intervention. If the humidity rate remains too
high, change the lter drier again, start the unit, and run it for another day.
Page 45
43SysAqua
17.3.1.4. AIR COOLED CONDENSER
Caution
Fin edges are sharp and can cause injury hazard. Avoid contact with them.
Condenser coils are composed of copper tubes and aluminium ns. In case of leaks due to damage or
shock, the coils must be repaired by one of the authorized Support Centres. To guarantee the best possible
operation of the condenser bank, the condenser surface must be maintained as clean as possible, and it
must be void of foreign materials (leaves, wires, insects, slag, etc.). A dirty coil will see its absorbed electrical
power increase. In addition, condensation pressure could increase and trigger a high pressure alarm.
Clean the air exchanger using a special product for aluminium-copper coils and rinse with water. Do not use
hot water nor steam, as these may increase the refrigerating uid's pressure.
Caution
Avoid damaging the aluminium ns during cleaning. Never use pressurized water without a wide
diffuser. Concentrated and/or rotating water jets are strictly forbidden.
17.3.2. HYDRAULIC CIRCUIT
17.3.2.1. PLATE HEAT EXCHANGEUR
English
Verify the pressure difference between the inlet and the outlet of the heat plate exchanger. If the water
pressure and ow rate values do not correspond to the pressure loss curves available in § HYDRAULIC
PUMPS CURVES, page XI , the heat plate exchanger may be foul up. To clean it, use a non corrosive
solvent to remove calcareous deposits. The equipment used for the external water ow, the quantity of
solvent and safety measures applied must be approved by the company supplying the cleaning products, or
the one performing these operations.
17.3.2.2. PROCEDURE TO SWITCH FROM ONE PUMP TO OTHER
The procedure to switch from one pump to the other is the following
in case of pump 1 failure (for example) :
1. Turn the main power switch of the SysAqua in position OFF
2. Close the upstream and downstream valves of the
pump 1 (see photo)
3. Open the upstream and downstream valves of the
pump 2

44 SysAqua
17.3.3. WINTER PROTECTION
In winter, after a general stoppage of the installation or a regulation malfunction, the water contained in the
hydraulic circuit may start freezing.
To prevent any problems if the hydraulic circuit is not glycolated, it is recommended to fully drain any circuits
not used and to pressurize them with nitrogen or protect them by adding an anti-freeze solution or other
measures.
The concentration of anti-freeze solution must be regularly and carefully checked before each winter
season.
Caution
The manufacturer waives any liability for damage of a plate exchanger caused by water freezing
of water contained inside does not engage the responsibility of the manufacturer with respect to
this incident (low winter temperature or water start temperature below 5°C in summer mode).
CAUTION
BEFORE CARRYING OUT ANY OPERATION ON THE EQUIPMENT, CHECK
THAT THE ELECTRICAL POWER SUPPLY IS SWITCHED OFF AND THAT IT
CANNOT BE SWITCHED ON INADVERTENTLY.
IT IS RECOMMENDED THAT THE DISCONNECT SWITCH BE PADLOCKED
