9. INSTALLATION
9.1. SITING THE INSTALLATION
The SYSAQUA BLUE must be installed outdoors with sufcient surrounding clearance to enable air to circulate
freely through the appliance and to allow 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 at the nned battery. Exchanger fan
operation can be disrupted by strong winds, which can cause de-icing problems and fan malfunctions.
Depending on outdoor temperature and air humidity conditions, water vapor contained in the air can
condense on the nned heat exchanger and even form ice at low outdoor temperatures (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. This will allow the water to run off freely and be absorbed into the
ground or channeled to a basin built under the appliance in order to protect the environment.
In areas where outdoor temperatures drop below 1°C, the system can be equipped with a condensate anti-
freeze protection system (e.g. a heated pipe sheath, optionally available).
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 taking 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 bounce off
walls.
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 building structure (structure-borne
noise transmission).
²Electrical and hydraulic connections to the unit must be exible to avoid the transmission of
vibrations.
9.1.1. PREVAILING WIND
9.1.2. CONDENSATE WATER MANAGEMENT IN HEATING MODE
9.1.3. REDUCING NOISE POLLUTION
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
damage, which could prove hazardous to personnel and property. In such an event, the warranty
shall be voided.
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 BLUE to rejections from chimneys or vents. Fumes charged with soot
or grease as well as acid rejections are likely to permanently clog or damage the condenser. This
would void the warranty.
Caution
As per standard EN378-1 §5.1, the SYSAQUA BLUE unit is a category A installation in terms of access and a
class III installation in terms of location.

9.2. CLEARANCE
9.3. ANCHORING TO THE GROUND
The surface of the oor or structure located under the SYSAQUA BLUE must be at, and strong enough to
withstand the unit's weight with its full liquid load, in addition to the occasional presence of maintenance
equipment.
For normal applications, rigidity of the SYSAQUA BLUE and the positions of the supports allow for an
installation that minimizes vibrations. However, the installers can use anti-vibration rubber pads (supplied
as an option).
The SYSAQUA BLUE only needs to be anchored to the foundations in regions exposed to a high earthquake
risk or if the appliance is installed at a high level on a steel frame.
When tting anti‑vibration pads, refer to the manual supplied with the kit.
When several SYSAQUA BLUE units are installed, ensure proper clearance is implemented around the
condensers specic to each machine.
Caution
SYSAQUA BLUE 35B SYSAQUA BLUE 35B
WITH BUFFER TANK
The unit is equipped with a R290 refrigerant leak
detection card enabling it to be shut down and for
the hydrocarbon to be expelled into the atmosphere
(before reaching the uid ammability limit). To
ensure this, two apertures are present on the frame:
the rst, equipped with an extractor fan, sucks
outside air into the frame and the second expels
waste air into the atmosphere.
These minimum clearance dimensions must be complied with to ensure correct operation of the unit, to
enable the unit to be accessed and maintained, and, above all, to guarantee the safety of personnel.
During installation, it is important to leave sufcient
clearance around the SYSAQUA BLUE.

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 hydraulic
components generating pressure drops 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) 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 adjust the water ow.
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 necessary for the operation of the SYSAQUA BLUE 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 gages 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 electrolytic corrosion.
10.2. ANTI-CLOGGING PROTECTION
Failure to install a water lter would result in clogging of the SYSAQUABLUE's heat plate exchanger soon after
commissioning. Proper operation of the SYSAQUA
BLUE would be disturbed by a reduced water ow
or the partial clogging of certain heat plates. The
heat plate exchanger could be IRREVERSIBLY
damaged in the event of inadequate water ow.
A mesh size of smaller than or equal to 800µm is
recommended
The mains hydraulic circuit will provide a constant water ow on the refrigerating uid/water plate
exchanger and in case of load variation.
Caution
When choosing and installing water pipes, you must consult and observe all current local standards,
regulations and instructions.
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
PHENOMENA.
Caution
To avoid anyrisk of foreign bodies entering the appliance and to guarantee operating performance,
IT IS IMPERATIVE TO INSTALL A WATER FILTER on the SYSAQUA BLUE inlet pipe.
Caution
THE MANUFACTURER'S WARRANTY IS VOID IF THE FILTER SUPPLIED WITH
THE SYSAQUA BLUE IS NOT INSTALLED TO PROTECT THE APPLIANCE
Caution

English
14 SYSAQUA BLUE
Before lling the installation, check it and remove any contamination such as sand, stones, welding
chips and other materials likely to damage the SYSAQUA BLUE.
Caution
For refrigeration only units, the total volume at the primary water circuit must never be below:
²air conditioning application
3.5 L/kW refrigeration power
²process application
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 BLUE 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 BLUE COOLING ONLY VERSION
10.3.2. SYSAQUA BLUE HEAT PUMP VERSION
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 these recommendations to be adhered
to, 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 adequate temperature stability.
10.4. MAXIMUM WATER VOLUME REQUIREMENTS
The maximum water volume is limited by the size of the unit's expansion tank and/or the expansion tank
present in the installation's hydraulic circuit. Expansion tanks must be sized according to the percentage of
glycol in the hydraulic circuit.
Fully rinse all water pipes before nal connection to the SYSAQUA BLUE.
When using an off-the-shelf acid rinsing solution, implement a temporary branching around the SYSAQUA
BLUE to prevent damaging internal components (particularly the plate exchanger, ow switch, pump...).
10.5. RINSING THE CIRCUIT
Optional internal water tank:
²SYSAQUA BLUE 35B 100L
The volume of the expansion tanks selected with single pump and double pump options are:
The expansion tank should be installed at the pump suction, and its pressure will be adjusted by taking into
account the whole hydraulic circuit.

15SYSAQUA BLUE
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 45%. The water
and glycol mixture must be precisely prepared before lling the hydraulic circuit. If the mixture is too
concentrated, the hydraulic circuit could be damaged and the SYSAQUA BLUE unit will not perform
normally. In this case, the unit warranty will be automatically voided.
Caution
The percentage of glycol 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 destruction of the unit's heat exchanger.
Caution
10.6. FROST PROTECTION
If the SYSAQUA BLUE is exposed to ambient temperatures between 1°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 service life.
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 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 the environmental directive
applicable on site (this is not the manufacturer's responsibility).
The glycol‑based solution slightly modies the installation's performance, particularly in terms of load loss:
Minimum outdoor temp. °C 5 > T > 0 0 > T > -5 -5 > T > -10 -10 > T > -30

Example for a solution with 20% Mono Ethylene Glycol:
²Increase the pressure drop: with glycol = 1.160 x without glycol
²Increase the owrate: with glycol = 1.050 x without glycol
²Decrease the capacity: with glycol = 0.985 x without glycol

Warning
It is advisable to clearly record the type of glycol used, as well as the glycol concentration, on the
electric cabinet.

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 untreated water in the SYSAQUA BLUE may cause scaling, erosion, corrosion or
algae or sludge deposits in the exchangers. Refer to a water treatment expert to determine any treatment
required. The manufacturer will not be held liable for damage caused when untreated or improperly treated
water, demineralized water, salt water or seawater 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 pitting. <10mg/l.
²SO42- sulphate ions may cause pitting corrosion. < 30mg/l.
²No uoride ions (<0.1 mg/l)
²No Fe2+ and Fe3+ ions, particularly in the 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: Values between 10°fH and 30°fH may be recommended. This facilitates scaling
deposits likely to limit copper corrosion. Excess TH values may lead to clogging of 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 sparging pure oxygen.
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 favors maximum resistivity. For electrical
conductivity, values around 200-600 S/cm can be recommended.
²pH: neutral pH at 20°C (7 < pH < 9)
The SYSAQUA BLUE must not run on a network with open loops, likely to cause incidents related
to oxygenation, or with untreated ground water.
Caution
If the water circuit is to be drained for a period of longer than 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 regarding water treatment (call a specialized
company).
However, this matter has a critical nature, and particular care must be taken to ensure that the type
of treatment applied is effective.
The manufacturer or the latter's representative will not be held liable when untreated water or
non-compliant quality water is used.

When two or three units are connected in parallel, it is advisable to reverse the return circuit connections
(Tichcelmann loop) in order to reduce the pressure loss in each unit’s circuit.
Always check that manual or automatic air drains are installed at all the high points of the hydraulic network.
Install a balancing valve on the output pipe to adjust the water ow.
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 sufcient to ll the installation.
Once the installation is complete and after cleaning and rinsing 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
When the hydraulic pump option is selected, a safety
valve is mounted (factory assembled) at the Aqualogic
water inlet to prevent overpressure in the circuit. The
installer must install a pipe at the safety valve outlet
for water evacuation.
A 3.5-bar safety valve is mounted in the unit when the hydraulic single pump option is selected.
The water inlets and outlets must be connected as described on the labels afxed near the
connections.
Caution
THE WATER CIRCUIT MUST BE FILLED AND DRAINED BY SKILLED PERSONS USING THE APPROPRIATE
DEVICES PROVIDED ON THE EXTERNAL HYDRAULIC CIRCUIT BY THE INSTALLER.
