4.1 Safety Considerations RXYMQ-M
Please read these SAFETY CONSIDERATIONS carefully before installing air conditioning equipment, and be sure to install it
correctly. After completing installation, make sure the unit operations properly during startup operation.
Instruct the customer how to operate and maintain the unit.
Always use a licensed installer or contractor to install this product. Improper installation can result in water or refrigerant leakage,
electrical shock, fire, or explosion.
Meaning of danger, warning, caution and note symbols.
DANGER .............. Indicates an imminently hazardous situation which, if not avoided, results in death or serious injury.
WARNING ............ Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION ............. Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It
may also be used to alert against unsafe practices that may cause property damage.
NOTE.................... Indicates a statement of company policy directly or indirectly related to the safety of personnell or pro-
tection of property.
DANGER
• Refrigerant gas is heavier air and replaces oxygen. A massive leak can lead to oxygen depletion, especially in base-
ments, and an asphyxiation hazard can occur leading to serious injury or death.
• Do not ground units to water pipes, telephone wires or lightning rods because incomplete grounding could cause a
severe shock hazard resulting in severe injury or death, and to gas pipes because a gas leak could result in an explo-
sion which could lead to severe injury or death.
• Do not install unit in an area where flammable materials are present due to risk of explosion resulting in serious injury
or death.
• Any abnormalities in the operation of the air conditioner such as smoke or fire could result in severe injury or death.
Turn off the power and contact your dealer immediately for instructions.
• If the refrigerant gas leaks during installation, ventilate the area immediately.
Refrigerant gas may produce toxic gas if it comes in contact with fire such as from a fan, heater, stove or cooking
device. Expo-
sure to this gas could cause severe injury or death.
• After completing the installation work, check that the refrigerant gas does not leak.
Refrigerant gas may produce toxic gas if it comes in contact with fire such as from a fan, heater, stove or cooking device. Expo-
sure to this gas can cause severe injury or death.
• Do not install the unit in an area where flammable materials are present due to risk of explosion resulting in serious
injury or death.
• Safely dispose of the packing materials.
Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries.
• Tear apart and throw away plastic packaging bags so that children will not play with them.
Children playing with plastic bags face danger of death by suffocation.
WARNING
•
Perform installation work in accordance with this installation manual.
Improper installation may result in water leakage, electric shocks or fire.
• Be sure to use only the specified accessories and parts for installation work.
Failure to use the specified parts may result in water leakage, electric shocks, fire or the unit falling.
• Install the air conditioner on a foundation strong enough to withstand the weight of the unit.
A foundation of insufficient strength may result in the equipment falling and causing injuries.
• Do not remove the front panel because some parts inside are dangerous to touch. In addition, some parts may be
damaged by touching. For checking and adjusting internal parts, contact your dealer.
• Carry out the specified installation work after taking account of strong winds, typhoons or earthquakes.
Improper installation work may result in the equipment falling and causing accidents.
• Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried out by
qualified personnel according to local laws, regulations and this installation manual.
An insufficient power supply capacity or improper electrical construction may lead to electric shocks or fire.
• Make sure that all wiring is secured, the specified wires are used, and no external forces act on the terminal connec-
tions or wires.
Improper connections or installation may result in fire.
• When wiring the power supply and connecting the remote controller wiring and transmission wiring, position the
wires so that the electric parts box lid can be securely fastened.
Improper positioning of the electric parts box lid may result in electric shocks, fire or the terminals overheating.

- The installer and system specialist must follow proce dures to prevent leakage according to local regulations or standards the following standards may be applicable if local regulations are not available 29
- The vrv system like other air conditioning systems uses r 410a which is an entirely safe non toxic non combustible refrigerant nevertheless care must be taken to ensure that air conditioning facilities are installed in rooms large enough to ensure that in the unlikely event of a major leak the maxi mum concentration level of refrigerant gas is not exceeded maximum concentration level the maximum charge of refrigerant and the calculation of the maximum concentration of refrigerant is directly related to the humanly occupied space in to which it could leak the unit of measurement of the concentration is lb f 29
