Read these Safety summary carefully before installing an air conditioner or heat pump. After completing
the installation, make sure that the unit operates properly during the startup operation. Inform users that
they should store this 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.
•
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.
•
Do not install the unit in the following places. It may cause a fire, deformation, corrosion or failure.
○ Places where oil (including machinery oil) may be present in quantities.
○ Places where a lot of sulfide gas drifts such as in a hot spring.
○ Places where flammable gas may generate or flow.
○ Places where strong salty wind blows such as coast regions.
○ Places with an atmosphere of acidity or alkalinity.
•
Do not install the unit in the place where silicon gas drifts. If the silicon gas attaches to the surface of
heat exchanger, the fin surface repels water. As a result, drain water splashes outside of the drain pan
and splashed water runs inside of electrical box. In the end, water leakage or electrical devices failure
may occur.
•
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.
•
Do not pour water in the indoor or outdoor unit. This product contains electrical components and if
wet, can cause serious electrical shock.
•
Do not open the service cover or access panel for the indoor or outdoor unit without turning OFF the
main power supply.
•
Do not touch or adjust safety devices inside the indoor unit or outdoor unit. If these devices are touched
or readjusted, it may cause a serious accident.
•
Use an ELB (Earth Leakage Breaker). In the event of fault, there is danger of an electric shock or a fire if
it is not used.
•
For installation, firmly connect the refrigerant pipe before the compressor starts operating.
For maintenance, relocation and disposal, remove the refrigerant pipe after the compressor stops.
•
Do not perform a short-circuit of the protection device such as the pressure switch when operating. It
may cause a fire and explosion.
