1. SAFETY CONSIDERATIONS
Read these
SAFETY CONSIDERATIONS for Installation
carefully before installing air conditioning equipment. After
completing the installation, make sure that the unit operates
properly during the startup operation.
Instruct the customer on how to operate and maintain the
unit. Inform customers that they should store this Installation
Manual with the Operation Manual for future reference.
Always use a licensed installer or contractor to install this
product. Improper installation can result in water or refrigerant
leakage, electric shock, fire, or explosion.

DANGER
•
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.
•
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.
•
If refrigerant gas leaks during installation, ventilate the
area immediately. Refrigerant gas may produce toxic gas
if it comes in contact with fire. Exposure to this gas could
cause severe injury or death.
•
After completing the installation work, check that the
refrigerant gas does not leak throughout the system.
•
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.
WARNING
•
Only qualified personnel must carry out the installation
work. Installation must be done in accordance with this
installation manual. Improper installation may result in
water leakage, electric shock, or fire.
•
When installing the unit in a small room, take measures
to keep the refrigerant concentration from exceeding
allowable safety limits. Excessive refrigerant leaks, in the
event of an accident in a closed ambient space, can lead
to oxygen deficiency.
•
Use only specified accessories and parts for installation
work. Failure to use specified parts may result in water
leakage, electric shocks, fire, or the unit falling.
•
Install the air conditioner or heat pump on a foundation
strong enough that it can withstand the weight of the unit.
A foundation of insufficient strength may result in the unit
falling and causing injuries.
•
Take into account strong winds, typhoons, or earthquakes
when installing. Improper installation may result in the unit
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, state and national
regulations. An insufficient power supply capacity or
improper electrical construction may lead to electric
shocks or fire.
