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.

or damage to property in the event of the unit being incorrectly supported.
Caution
1. The installer must ensure that access under the suspended ceiling is provided, and that sufcient
space is provided for the suspension angle brackets, the duct attachment collars and the water and
electrical connections.
2. Provide space under the unit for a siphon on the condensates drainage pipe. Do not install the unit
on top of pipe work.
3. Each unit is suspended from the ceiling on four threaded rods. The rods are attached through the
shock mounts to the corners of the unit by suspension angle brackets.
Warning! Do not use rods of a diameter smaller than that stated below. The rods must be solidly
anchored to the ceiling and to the ceiling joists.
4. Each unit is supplied with a set of pre-tted suspension angle brackets and a tting kit contained in
the pouch with the technical manual. The kit comprises 4 shock mounts, 4 washers, 4 nuts and 4
locknuts.
5. Arrange the threaded rods in accordance with the dimensions stated below. The use of nuts and

17SYSHRW
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.
