DANGER
!
•
Hitachi is not able to foresee all the circumstances which may result in a potential danger.
•
Do not pour water in the indoor or outdoor unit. These products are fitted with electric components.
If water comes into contact with electric components, it will cause a serious electric shock.
•
Do not handle or adjust the safety devices inside the indoor and outdoor units. The handling or
adjustment of these devices may result in serious accident.
•
Do not open the service cover or access panel of the indoor and outdoor units without disconnecting
the main supply.
•
In the event of fire, switch off the mains, put out the fire immediately and contact your service
supplier.
•
Check that the earth cable is correctly connected.
•
Connect the unit to a circuit breaker of the specified capacity, refer to "6.1 General Information" for
details.
•
The storage of equipment should be in accordance with the manufacturer's instructions.
•
Do not install pipe work with diameters that are not specified for that model.
•
Do not ground units to water pipes, gas pipes, telephone wires, or lightning rods as incomplete
grounding can cause a severe shock hazard resulting in severe injury or death. Additionally, grounding
to gas pipes could cause a gas leak and potential explosion causing severe injury or death.
•
Do not install unit in an area where flammable materials are present due to risk of explosions that can
cause serious injury or death.
•
Safely dispose all packing and transportation materials in accordance with federal/state/local laws or
ordinances. Packing materials such as nails and other metal or wood parts, including plastic packing
materials used for transportation may cause injuries or death by suffocation.
•
Refrigerant gas is heavier than air and replaces oxygen. A massive leak can lead to oxygen depletion,
especially in basements, and an asphyxiation hazard could occur leading to serious injury or death.
•
If refrigerant gas leaks during installation, ventilate the area immediately. Refrigerant gas may
produce toxic gas if it comes into contact with fire. Exposure to this gas could cause severe injury or
death.
