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.

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, electricity
and duct connections.
2. 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.
3. Provide space under the unit for a siphon on the
condensates drainage pipe. Do not install the unit on
top of pipe work.
4. 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.
5. 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.
6. Arrange the threaded rods in accordance with the dimensions stated below. The use of nuts and
locknuts is recommended for attaching the suspension rods to the unit as the unit’s vibrations may
loosen a single nut. The installer is liable for any damage in the event of this recommendation not
being followed.
7. To facilitate drainage, the unit must be angled in both
planes towards the condensates drainage pipe. (Slope
minimum: 2 %)
It is also possible to use a

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.

11.4. FILTER ACCESS
The lter can be removed either from the side 1or from the top 2without having to dismantle the connection
duct.
The units can be delivered congured either for frontal air return, known as "In LINE" or for side air return. It
is also possible to modify the return air conguration onsite by proceeding as follows:
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 7).
11.5. VENTILATION
1. Remove the access panel 1.
2. Remove the air return panel 2.
3. Fit the return air panel 2in the location
previously occupied by the access panel 1.
4. Ret the access panel 1.

13. HYDRAULIC LINKS
13.1. 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 SYSLOOP EVO 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)
THE WARRANTY DOES NOT COVER DAMAGE DUE TO CORROSION RESULTING FROM ELECTROLYTIC
PHENOMENA.
Caution
The SYSLOOP EVO must not run on a network with open loops, likely to 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.

13.2. 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. The condensates drainage line must comprise a siphon and run from the unit on a downward
slope of at least 2%. Generally, the siphon is connected directly to the unit’s condensates
drainage outlet. A length of plastic pipe can be used between the siphon and the condensates
drainage line.
A complete condensates drainage system with copper or P.V.C. pipe can also be used.
Screw-on connectors shall be tted to facilitate drainage pipe removal if copper pipe is used for
the drainage pipe work.
10. No point of the condensates drainage pipe work should be located above the level of one of
the units’ condensate drainage outlet connection.
11. The circuits’ high points must be bled of air.
12. 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.
