The SYSCOIL COMFORTmust not run on a networkwith open loops, likelyto 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
11SYSCOIL COMFORT
8.6. 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 SYSCOIL COMFORT 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: 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 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 < 9)

9.3. ELECTRICAL CONNECTIONS

English
Manufacturer or its representative cannot be held responsible for accidents resulting from
incorrect or non-existent earthing.
Caution
The electrical heating resistances must never operate without ventilation.
Caution
Do not connect several units to a single ventilation speed selector or regulation thermostat
without using auxiliary relays.
Check that the current absorbed by the motors is compatible with the cut-out capacity of the
control device contacts.
Caution
13SYSCOIL COMFORT
If the local control includes an remote ambient temperature sensor and/or a set temperature adjustment
module, these shall be connected with shielded cable and shall not pass through the same conduits as the
power supply cables as the voltages induced may create reliability faults in the unit’s operation.
Before making the connections, be sure that the available power supply has the same voltage and phase as
that shown on the fan coil unit nameplate.
Each fan coil unit is supplied with a terminal strip located on the opposite side of piping connections.
Line and low voltage wiring must be done in accordance with electrical code whichever is applicable.
Earthing of unit is imperative.
Note: if electrical wiring or conduit comes through the oor, they must be tight along their passage through
the oor.
9.4. OPTIONAL ELECTRIC HEATER
On request, all fan coil units can be factory mounted with an electric heater.
Do not install the electric heater on existing unit without using the supply air grilles resistant to high
temperature.
Factory-tted electric heating batteries are equipped with an automatic and manual reset temperature
limiting safety device in compliance with IEC 66375.
9.5. CONTROLS
As standard, the units are supplied without regulation equipment.
However, certain control devices (fan speed selector, remote thermostat, etc.) can be supplied according to
request.
If a TRM remote temperature regulation thermostat is supplied, it must only control a single unit. If this
is not the case, you must include a relay box in the circuitry.
