1.3. EQUIPMENT SAFETY DATA
Safety Data R407C
Toxicity Low
In contact with skin
Liquid splashes or sprays may cause freeze burns. Unlikely to be hazardous by skin absorption.
However, R407C may be slightly irritant and, if liquid, it has a strong degreasing effect. Flush contaminated skin
areas with running water. If it comes into contact with fabrics, the liquid refrigerant will cause them to freeze
and adhere to the skin. Carefully remove the contaminated clothing since it might adhere to the skin and cause
freeze burns. Contact a doctor if the affected skin areas are reddened or irritated.
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 Very unlikely to occur. If this should be the case, it may cause freeze burns. Never induce vomiting. Keep the patient awake. Make him rinse his mouth with running water and make him drink about 1/4 of a litre.
Immediately contact a doctor.
Inhalation
R407C: High concentration levels of its vapours in the air can produce an anaesthetic effect, including the loss of
consciousness. Particularly severe exposures may cause heart arrhythmia and sometimes prove to be also fatal.
At high concentrations there is a danger of asphyxia due to a reduced oxygen content in the atmosphere.
In these cases take the patient to the open air, in a cool place and keep him at rest. Administer oxygen, if
required. Apply artificial respiration if breathing has ceased or if it has become irregular. In case of heart failure
immediately apply cardiac massage. Immediately contact a doctor.
Further Medical Advice
A symptomatic and supportive therapy is generally suitable. A heart sensitisation has been observed in some
cases, as a result of exposures to particularly high concentrations. In the presence of catecholamines (such
as for example adrenaline) in the blood flow, it has increased the irregularity of the cardiac rhythm and then
caused the heart failure.
Long-term exposure R407C: A lifetime study which has been conducted on the effects inhalation may have on rats at 50,000 ppm has shown the onset of benign tumours of the testicle. These remarks suggest that there is no danger for
human beings if they are exposed to concentrations below the occupational limits or equal to them.
Occupational exposure
limits R407C: Recommended limits: 1,000 ppm v/v 8 hours TWA.
Stability R407C: Not specified.
Conditions to avoid Use in the presence of exposed flames, red heat surfaces and high humidity levels.
Hazardous reactions Possibility of violent reactions with sodium, potassium, barium and other alkaline substances.
Incompatible materials: magnesium and all the alloys containing over 2% of magnesium.
Hazardous
decomposition
products R407 C: Halogen acids deriving from thermal decomposition and hydrolysis.
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 45°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 R407C: Non flammable in the atmosphere.
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.

Water circuit heat pumps are usually installed in conjunction with an air blowing duct. A return air duct may
also be required. All ductwork shall be compliant with best air conditioning engineering practices.
The air blowing duct system normally consists of a exible connector mounted on the unit, a bridging
section to link to the size of the main duct, a short section of straight duct, an elbow without a damper and
a main duct with spurs equipped with distribution grilles as illustrated in the drawing below. The sum total
of the bridging section angles must not be higher than 30°, otherwise there will be signicant performance
losses.
Do not connect the main duct directly to the unit without a bridging section to reduce the duct size to that of
the unit’s connection collar. In the event of using metal ducts, only the sides of the elbow section and all the
spur duct sections should be covered with breglass sound insulation for reducing the noise level. Fibreglass
duct panels are more sound absorbent and may enable the exible canvas connection to be eliminated.
The duct network must be laid out to avoid any rectilinear runs betweens the heat pump outlet and the air
distribution outlets.
The return air intake ducts can be connected to a grille/lter located at the base of a wall, then directed via
hollow partitions towards a ceiling mounted plenum or via ceiling mounted grilles. The ceiling grilles must
not be located directly below the air conditioning unit.
The return air intake duct can be connected directly to the standard lter bracket. (Lateral lter removal
advisable).
Do not drill panel screws directly into the unit’s casing for connecting the blowing and return air intake ducts,
especially on the air return side, as there is a risk of damaging the condensate recovery tray and the battery.

The ow / static pressure adjustment is made with the aid of a variable pulley. When adjusting this pulley,
it is important to ensure that the belt is positioned properly. The pulleys / belt assembly must be aligned
perfectly and the belt tensioned in accordance with best practices.
11.2. FILTER ACCESS
Each unit is supplied with a connection frame also serving as the lter support. This enables to lter to be
removed from the side without having to dismantle the duct or the connection frame.
An outdoor air intake (new air) may be required for ventilation. The blown air temperature must be
controlled in order to avoid the temperature of the mixture of outdoor air and return air at the heat pump
inlet exceeding the appliance’s operating limits. It is also common practice to shut down ventilation during
periods of inoccupation (night time setting of the set temperature).
Each appliance’s ventilation system is generally a sub-system within the building, with its own distribution
duct network. The simple introduction of outdoor air into each return air plenum, quite close to the unit’s
return air intake is sufcient and recommended. New air should not be introduced directly into the appliance.
Provide for a sufcient distance to ensure effective mixing of the outdoor air with the return air. (Refer to
the § OPERATING LIMITS, page 9).

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
THE WARRANTY DOES NOT COVER DAMAGE DUE TO CORROSION RESULTING FROM ELECTROLYTIC
PHENOMENA.
Caution
The SYSHRW must not run on a network with open loops, likely to cause incidents related to
oxygenation, or with non treated table water.
Caution
12. HYDRAULIC LINKS
12.1. 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 SYSHRW 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)
