Safety precautions
·Failing to properly secure electrical cover or service panel may result in fire or electric shock.
·Cut off the main power supply before the installation of indoor electronic PCB or wiring. Otherwise,
it may cause electric shock.
·Equipment shall be in accordance with the state provisions for installation wiring.
·Carefully select the outdoor unit installation location in order to avoid people or other small animals
contact with electrical components, please keep the outdoor unit of the surrounding environment
clean and tidy.
·When installing or relocating equipment, make sure that no substance other than the specified
refrigerant (R410A) enters the refrigerant circuit.
Presence of foreign substance such as air can cause abnormal pressure rise, mal function, or an
explosion.
·Perform grounding
Do not connect the earth wire to a gas pipe, water pipe, lightning rod, or telephone earth wire.
Defective grounding may cause electric shock.
·Do not install the equipment in a location where there is potential for an flammable gas leak.
Flammable gas leaks in the area surrounding the equipment may cause an explosion.
·Tighten flare nuts with a torque wrench as specified in this manual.
If tightened too tight, a flare nut may break after a long period and cause a leakage of refrigerant.
·Install an earth leakage breaker depending on the installation place (humid location).
Failing to use earth leakage breakers in a humid environment may cause electric shock.
·Perform drainage/piping work securely according to the installation manual.
·If there is a defect in the drainage/piping work, water could drop from the unit and household goods
