1.4. 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 breathing 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.
2. Inspection and storage
At the time of receiving the equipment carefully cross check all the elements against the shipping documents in order to ensure
that all the crates and boxes have been received. Inspect all the units for any visible or hidden damage.
In the event of shipping damage, write precise details of the damage on the shipper’s delivery note and send
immediately a registered letter to the shipper within 48 hours, clearly stating the damage caused. Forward a copy of
this letter to the manufacturer or his representative.
Never store or transport the unit upside down. It must be stored indoors, completely protected from rain, snow etc. The unit
must not be damaged by changes in the weather (high and low temperatures). Excessively high temperatures (above 60°C)
can harm certain plastic materials and cause permanent damage. Moreover, the performance of certain electrical or electronic
components can be impaired.

8.2. Refrigeration specifications
8.2.1. Refrigerant circuit diagram
See appendix
8.2.2. Refrigerant charge
CAUTION This equipment contains fluorinated gas with greenhouse gas effects covered by the Kyoto agreement.
The type and quantity of refrigerating fluid per circuit are indicated on the product plate.
The installer and end user will get informed on local environmental regulations for the installation, operation and disposal of the
equipment ; more particularly, for the collection of substances hazardous for the environment (refrigerating fluid, oil, antifreeze,
etc.). A refrigerating fluid, whatever it is, must not be vented. Refrigerating fluids must be handled by skilled personnel.
CAUTION
ECOi-W units use the R410A fluoro-carbonated fluid, belonging to group 2 as defined in directive 2014/68/
UE. Considering the maximum operating pressure of these units (42 bar g), they integrate category 2 (or
lower) components as defined in directive 2014/68/UE.
8.2.3. Fluorocarbon gas regulations
The EC No. 517/2014 regulation covering fluorinated greenhouse gases requires of refrigeration equipment operators to
comply with the following five obligations:
1. Installation, servicing, maintenance as well as checking the sealing must be carried out by qualified personnel.
2. The fluorinated gas must be recovered during servicing and maintenance as well as the end of the installation.
3. All the necessary measures must be taken to prevent the leakage of fluorinated gases and any leaks must be repaired as
rapidly as possible.
4. Regular checks on any leaks must be performed according to the following conditions:
- for equipment containing fluorinated greenhouse gases in quantities greater than or equal to the equivalent of 5 tonnes
of CO2but less than the equivalent of 50 tonnes of CO2: at least every twelve months or, if a leak detection system is
installed, at least every twenty-four months
- for equipment containing fluorinated greenhouse gases in quantities greater than or equal to the equivalent of 50 tonnes of
CO2but less than the equivalent of 500 tonnes of CO2: at least every six months or, if a leak detection system is installed,
at least every twelve months
- for equipment containing fluorinated greenhouse gases in quantities greater than or equal to the equivalent of 500 tonnes
of CO2: at least every three months or, if a leak detection system is installed, at least every six months.
5. A document grouping a description of all the operations carried out on the cooling circuit must be drafted and conserved.
CAUTION
Non-compliance with one of these obligations constitutes an offense and can result in financial penalties.
Furthermore, compliance of the equipment with the fluorinated gases regulation must be proven to the
insurance company.
8.2.3.1. Calculating greenhouse gas quantities
Greenhouse gas quantity (kg of CO2) = Quantity of gas (kg) x gas’ GWP
Quantity of greenhouse gas expressed in weight (kg) and CO2 equivalent
Quantity of gas: amount of gas contained in the machine in kg (see ID plate)
GWP (Global Warming Potential) of the gas contained in the machine (see ID plate)

9. Installation
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 ECOi-W must be installed outdoors with sufficient surrounding clearance to enable unobstructed air circulation through
the appliance and access for maintenance work.
CAUTION Do not expose the ECOi-W to emissions from chimneys or vents. Fumes charged with soot or grease as
well as acidity are likely to clog or damage the condenser irrevocably. This would void the warranty.
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.
CAUTION 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.
9.1.1. Condensate water management in heating mode
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 aid water run-off and avoid frozen water remaining in the
appliance in winter, we recommend that it is mounted at a height ≥100mm above the ground or supporting structure. In this
way, 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, optional accessory not supplied with the standard unit).
9.1.2. 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:
• Do not install the appliance near a window.
• Do not install the unit in enclosed or confined yards, narrow locations where noise may be reflected on walls.
• Install rubber pads or anti-vibration pads (available as an option) under the appliance.
• Do not join the concrete slab supporting the appliance to the structure of the dwelling (structure- borne noise transmission).
• Electrical and hydraulic connections to the unit must be flexible to avoid transmitting vibrations.

15
9.2. Clearance
When choosing the location for the ECOi-W, 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.
CAUTION When several ECOi-W units are installed, ensure proper clearance is implemented around the condensers
specific to each machine.
9.3. Attachment to the ground
The surface of the floor or structure located under the ECOi-W must be flat, and with sufficient strength to withstand the unit’s
weight with its full liquid load, and occasional presence of maintenance equipment.
For normal applications, rigidity of the ECOi-W and the
positions of supports allow for an installation minimizing
vibrations. However, the installers can use anti-vibration
rubber pads (supplied optionally).
The ECOi-W 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 fitting anti-vibration pads, refer to the manual supplied with the kit.

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 main hydraulic circuit will provide a constant water flow on the refrigerating fluid/water plate exchanger
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 help to reduce installation costs and ensure optimum system performance. The pipe network must include:
• A 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.
• A balancing valve on the water outlet pipe in order to adjust the water flow.
• Stop cocks to isolate the hydraulic circuit during maintenance.
• Manual or automatic bleed valves at the highest points on the water circuit.
• Drain points at all low points to allow complete circuit draining
• A circulation pump guaranteeing flow necessary for the operation of the ECOi-W unit. This may be a pump fitted within the
unit.
• A diaphragm expansion tank fitted with a safety pressure relief valve and draining valve must be visible.
• A low water pressure sensor (available as option), to secure the water pump against cavitation if the water pressure in the
circuit decreases.
• The installation of thermometers and pressure gauges on the heat exchanger inlet and outlet to facilitate day-to-day controls
and system maintenance.
• An element ensuring ground continuity of all piping. An unbalance of grounding connection points can cause electrolytic
corrosion.
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.
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 ECOi-W inlet pipe.
Failure to install the filter to the inlet of the ECOi-W
could result in blockage within the plate heat
exchanger. Should there be insufficient water flow rate,
it may result in IRREVOCABLE damage.
A filter mesh ≤800µm is required.
CAUTION The manufacturer’s warranty is void
if the filter supplied with the ECOi-W is not installed to protect the appliance.

17
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 ECOi-W and the main network. Proper operation of the control and safety devices is ensured only when the water
volume is sufficient.
For cooling only operation, the total volume on the level of the primary water circuit must never below:
• application air conditioning
- 3,5 L/kW refrigeration power
• application process
- 10 L/kW refrigeration power
When utilising heating mode, a water volume equal to 6,5 L/kW is recommended, so that energy reserves are 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 or volumiser
must be added to the installation, to increase the water volume up to the minimum required value.
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 or
volumiser is compulsory to guarantee sufficient thermal inertia and satisfactory temperature stability.
A buffer tank can be required to increase the water volume of the whole hydraulic circuit in the system, so as to reach the
minimum water volume requested.
Internal buffer tank:

Minimum water volume in the system L935 1000 1106 1268 1415
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:
140 150 170 190 210
Volume of the expansion tank supplied with hydraulic options L25 25 25 25 25
10.5. Rinsing the circuit
CAUTION Before filling the installation, check it and remove any contamination such as sand, stone, welding chips
and other materials likely to damage the ECOi-W.
Fully rinse all water pipes before final connection to the ECOi-W.
When using an off-the-shelf acid rinsing solution, implement a temporary branching around the ECOi-W to prevent damaging
internal components (particularly the plate exchanger, flow switch, pump...).

18
10.6. Frost protection
10.6.1. Water loop glycoling
CAUTION The use of a glycol-based solution is the only effective frost-protection means
The glycol-based water solution must be sufficiently concentrated to ensure appropriate protection and prevent ice from
forming. 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 directives applicable on site (this is
not under manufacturer responsibility).
CAUTION
Glycol concentration in the installation’s hydraulic circuit must be entered in the controller upon start-up.
This parameter setting changes the safety and alarm triggering threshold limits. An incorrect value may
cause malfunctions and potential 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.
Glycoling the water loop worsens slightly the performances, in particular the pressure drops. The hereunder table gives
corrective factors with respect of type and concentration of the glycol. For instance, the 20% MEG glycoling will:
• Increase the pressure drop: with glycol = 1,160 x without glycol
• Increase the flow rate: with glycol = 1,050 x without glycol
• Decrease the capacity: with glycol = 0,985 x without glycol

Water flow 1,005 1,030 1,067 1,162
Thermodynamic power 0,991 0,977 0,945 0,894
Draining the water circuit is not recommended for frost protection, for the following reasons:
• The water circuit will rust, which will shorten its lifetime.
• Water will remain at the bottom of the plate exchangers and freezing may cause damage.
CAUTION
Never fill the hydraulic circuit with pure glycol. Maximum glycol concentration is 45%. The water and glycol
mixture must be precisely prepared before filling the hydraulic circuit. If the mixture is too concentrated, the
hydraulic circuit components may be damaged and the ECOi-W unit may not perform normally. In this case,
unit warranty will be void.
CAUTION For Heat pump models, if the outdoor temperature is likely to fall below +1°C, provide means to prevent the
condensates from freezing (e.g. heating cord).
10.6.2. Outer air protection
In case of negative temperatures, the water loop must be protected against icing when the unit is off. Concentration must
comply with the temperature level:
Minimum outer air temperature °C 5 > T > 0 0 > T > -5 -5 > T > -10 -10 > T > -27
MEG concentration % 10 20 30 45
MPG concentration % 10 20 30 45

19
10.6.3. Leaving water protection
In case of low temperature setpoint or reduced water flow, the water loop must be protected against icing during the operation
of the unit. Concentration must comply with the minimum water temperature of the installation. The choice of the type of glycol
shall take in consideration the increase of pressure drops.
For instance, we recommend to protect a -10°C setpoint down to -18°C. Using MPG, that protection is achieved with a 35%
concentration.
10.7. Water quality
The water must be analyzed; the hydraulic network system installed must include all elements necessary for water treatment:
filters, additives, intermediate exchangers, drain valves, vents, check valves, etc., according to the results of the analysis.
CAUTION The ECOi-W must not run on a network with open loops, this is likely to cause incidents related to
oxygenation, or with non treated table water.
Using improperly treated or non treated water in the ECOi-W may cause scaling, erosion, corrosion, 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:
• No NH4
+ammonium ions in the water, highly detrimental to copper. <10mg/l
• Cl- chloride ions are detrimental to copper with a risk of puncture by pitting corrosion. <10mg/l.
• SO4
2- sulphate ions may cause perforating corrosion. < 30mg/l.
• No fluoride ions (<0,1 mg/l)
• 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.
• Dissolved silica: silica is an acid element of water and may also cause corrosion. Content < 1mg/l.
• 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.
• TAC<100
• 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.
• 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.
• 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.

20
10.8. 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 resistivity 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 sufficient to fill the installation.
Once the installation is complete and after having clean and rinsed out the circuit network, you must fill 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).
Always check that the manual or automatic air purge valves 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
(Tichelmann loop system) in order to reduce the pressure loss in each unit’s circuit.
Install a balancing valve on the output pipe to adjust the water flow.
CAUTION The water inlets and outlets must be connected as described on the labels affixed near the connections.
When the hydraulic pump option is selected, a safety valve
is mounted (factory assembled) at the Aqualogic water inlet
to prevent over pressurising the circuit. The installer must
install a drain pipe at the safety valve to allow for removal of
water.
