1.3. EQUIPMENT SAFETY DATA
Safety data R513A
Toxicity level Low.
In contact with the skin Dermal contact with the rapidly evaporating liquid can cause frostbite to the tissue. In the event of contact with the liquid, warm the frozen tissue with water and notify a physician. Remove
contaminated clothing and shoes. Wash clothes before reuse
In case of eye contact Steam has no effect. Splashing or splashing liquid can cause burns. Clean immediately with eye drops
or clean water for at least 15 minutes. Seek medical attention urgently.
Ingestion Burns can occur if this happens. Do not induce vomiting. When the patient is conscious, wash the
mouth with water. Seek medical attention urgently.
Inhalation If inhaled, move to fresh air and give oxygen if necessary. Perform artificial respiration if the patient is no longer breathing or is short of air. In the event of cardiac arrest, perform external CPR. Seek
immediate medical attention.
Other medical advice Cardiac sensitivity may, in the presence of circulating catecholamines such as adrenaline, lead to
increased arrhythmias and subsequent cardiac arrest if exposed to high concentrations.
Occupational exposure limits R513A: Recommended limit: 1,000 ppm - 8 hours.
Stability Room temperature stable product
Conditions to avoid Pressure build-up due to high temperatures can cause the container to explode. Protect from sunlight
and do not expose to a temperature >50°C.
Dangerous reactions Possibility of dangerous reactions in case of fire due to the presence of F and/or CI radicals
General precautions Avoid inhaling high concentrations of vapors. Atmospheric concentrations should be minimized and kept as far as possible below the occupational exposure limit. Steam is heavier than air and
concentrates at a low level and in small places. Exhaust ventilation at the lowest levels.
Respiratory protection If there is any doubt about the air concentration, breathing apparatus approved by the health services
should be used. These devices will contain oxygen or allow better breathing.
Storage The containers must be placed in a dry and cold place away from any risk of fire, direct sunlight and
away from any heat source such as radiators. Temperatures should not exceed 50°C.
Protective clothing Wear coveralls, impermeable gloves and goggles or a face shield.
Procedure in case of spillage or
a leak
Make sure that everyone wears the appropriate protective clothing and respirators. If possible isolate
the source of the leak. Encourage evaporation of small spills provided there is adequate ventilation.
Large spills: ventilate the area. Contain spill with sand, earth or other suitable absorbent material.
Prevent liquid from entering drains, sewers, basements and manholes as the vapor can create a
suffocating atmosphere.
Waste disposal Preferably to be recovered and recycled. If this is not possible, ensure that they are destroyed in an
authorized area able to absorb and neutralize acids and other toxic manufacturing products.
Fire fighting data R513A: Non-flammable at ambient temperatures and atmospheric pressures.
Containers Containers exposed to fire must be kept cold by means of water jets. Containers may burst if
overheated.
Fire protection equipment In case of fire, wear self-contained breathing apparatus and protective clothing.

10.1. SITING THE INSTALLATION
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
This equipment is designed EXCLUSIVELY for INDOOR installation.
In general, sheltered locations such as garages, roof space, etc, do not provide sufcient protection against
extreme temperatures and/or humidity and may be harmful to the unit’s performance, reliability and service
life.
1. To avoid any damage, this equipment must not be used to supply heating or cooling during building
work.
2. Check that the voltage, the number of phases and the capacity of the unit comply with the
installation plans.
3. Check the size of the unit in relation to the plans to ensure that the unit will be installed in the right
location.
4. Take particular care over the location and routing of the water pipes and the condensate drainage
pipe as well as the electrical wiring. The location and routing of these items must be clearly indicated
on the plans.
5. It is always advisable for the heat pump installer to consult with all the various entrepreneurs
responsible for the pipe work and electrical installation on the site.
6. We advise the installer to cover the appliances with a plastic sheet to protect it during the nal
building work.
This is particularly important if work such as spraying the joists with re retardant, sanding, spray
painting and plastering has not been completed.
The unit must be installed on a rm level foundation, of adequate strength to support its full operating
weight.
1. Install the unit in a location allowing easy removal of the lter and the access panels to the
electrical box/compressor and fan by leaving sufcient free space for servicing personnel to
perform maintenance and repairs. Leave sufcient space for the water and electricity connections.
2. The unit must be pitched slightly towards condensate drain outlet to provide positive drainage of
condensates.
3. We recommend the installation of a siphon on the condensate outow to avoid unpleasant odours
travelling back up the pipe.
4. All electrical and ductwork connections to the unit must be made via exible connections to prevent
transmission of vibration.
5. In addition to the service clearances noted on the dimension sheet it is essential that provision is
made for adequate and safe service access.
The units are designed to be installed in a controlled environment. Each unit should be located on the
installation plans. Inspect the carton for specic tagging numbers and references (models, size, left hand
or right hand). The supply, return and condensation piping should be located accordingly making sure the
piping will t into the connes of the fan coil chassis and cabinet.

Correct water treatment is critical, and particular care must be taken to ensure that the type of
treatment utilized is appropriate.
The recommendations of a company specializing in such matters must be sought and applied.
The manufacturer or their representative cannot be held liable in the event of the use of water
that is untreated or of nonconforming quality.
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 WARRANTY DOES NOT COVER DAMAGE DUE TO CORROSION RESULTING FROM ELECTROLYTIC
PHENOMENA.
Caution
The SYSCW-AR 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 SYSCW-AR 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)

12.2. RECOMMENDATIONS FOR HYDRAULIC CONNECTIONS
1. It is recommended that all units are connected to a water supply and return pipe system of
the Tickelman Loop type. The Tickelman Loop system is self-balancing and thus only requires
manual balancing if a large number of units with different ow and pressure loss characteristics
are connected to a single hydraulic loop. A very simple way of checking the hydraulic balance
is to measure the temperature difference between the water connections. To ensure a correct
water ow, the difference must be in the region of 3 to 7 °C in Cooling mode and 2 to 5°C in
Heating mode.
A system with two parallel pipes can also operate in a perfectly adequate manner, but it is more
difcult to achieve, and to maintain, balance.
2. Never connect a unit to the water supply and return lines without completely cleaning
and flushing out the hydraulic loop beforehand. After performing these operations, the
units must be connected, with all valves completely open, ready for the system to be lled with
water.
3. Water exchanger clogging reduces efcient appliance operation. We recommend the installation
of a strainer lter (Ø 0.8mm) on the appliance's water inlet pipe. The lter must be installed if
the water circuit cannot be cleaned. This lter should be installed between two cut-off valves
and it must remain easily accessible for the user so that it can be checked at regular intervals.
4. Steel, copper or P.V.C. pressure pipes may be used.
5. It is advisable to make the unit’s water supply and return conveyance lines with short lengths
of high-pressure hose, as they form excellent shock absorbers for unit operating noise and
hydraulic pressure surges.
One of the hose ends must be tted with a rotating connector to facilitate removal for
maintenance. Rigid pipes can be connected directly to the unit, but this is not recommended
due to their inability to absorb vibrations and noise.
Rigid pipes must be equipped with removable connectors to facilitate future removal of the unit
from its location.
6. Certain exible hose threaded connectors are supplied with sealing paste. If this is not the case,
use Teon tape to create a tight seal.
7. Each unit must be equipped with isolation valves on the water inlet and outlet pipes. The return
isolation valve is used for both cutting off the water supply and balancing the installation’s
water ow. As it is used to establish the balance of the ows, it must be equipped with a
lockable position end stop. This end stop ensures that, after the valve is closed, it can only be
re-opened as far as the position required to maintain a balanced water ow.

8. Use steel, copper or P.V.C. pipes for the condensates drainage pipe. Each unit is supplied with a
connector for condensates drainage.
9. No point of the condensates drainage pipe work should be located above the level of one of
the units’ condensate drainage outlet connection.
10. The circuits’ high points must be bled of air.
11. Comply with current regulations in terms of dielectric isolation of the connectors and the pipe
work.
1. Before commissioning an appliance for the rst time, the water loop must be cleaned and rinsed out
to remove any dirt and manufacturing debris.
If the appliances are equipped with isolation valves (either electric or pressostatic), the water
supply and return conveyance circuits to and from each machine must be connected to each other.
This will avoid any dirt being introduced into the units.
Flushing water through the units is acceptable if they are not
equipped with water ow control devices.
2. The system must be lled from the mains water supply. All air
bleeds must be open during lling. Close the air bleeds once
the system is lled.
The installer must start the main circulation pump with the
water top-up tap on the pressure reduction valve in the open
position. Check the air bleeds by increasing order of height to
ensure water ows freely throughout the entire system.
Power supply to the cooling tower must be shut down, and the
water loop temperature regulation thermostat must be set at
27 °C.
As the water circulates through the system, the installer must
seek out and repair any possible pipe work leaks. The drain
cocks, on the lowest points on the circuit, must be open for
ushing out and chasing out any impurities. Ensure that the
mains water valves are adjusted to allow water to enter at the
same speed as it exits. Check the pump inlet pressure gauge
and manually adjust the compensating valve to maintain the
same pressure before and after the opening of the drain taps. Flushing must be performed for at
least two hours, or longer if necessary, until clear and clean water is obtained at the drain taps.
3. Stop the additional heating and the water circulation pump. Open all the bleed points and the drain
taps to empty the system completely. The short-circuited water supplies and returns must now be
connected to the units’ inlet and outlet connections. It is recommended to use Teon tape on the
pipe connector threads. Do not use sealing paste on the hoses’ rotating connecters.
4. Formerly, sodium tri-phosphate used to be recommended as a cleaning agent for ushing.
However, nowadays numerous countries forbid the introduction of phosphates into their wastewater
networks. Therefore, it is now recommended that the system is ushed out with hot water (30 °C).
5. Fill the system again with clean water. Test the water acidity level (litmus paper), and treat as
required to obtain a slightly alkaline water quality.
At this stage, the recommended percentage of anti-freeze can be added. Use commercial quality
anti-freeze specically intended for air conditioning systems. Do not use automobile radiator anti-
freeze.
6. On the main electrical cabinet, adjust the heater set temperature point at 20 °C and the cooling
tower set temperature at 30 °C. Connect the power supply to all motors and start the circulation
pumps.
When the normal ow level has been reached through all components, including the cooler (irrespective
of the season) and when the air is bled form the system and the loop temperature has stabilised, each
appliance is ready to be checked, tested and started for balancing the air and water ows.
12.3. RECOMMENDATIONS FOR CLEANING AND FLUSHING OUT THE SYSTEM
