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.

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.

11.3. 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).
