SAFETY PRECAUTIONS
This air conditioner uses new refrigerant HFC(R32).
Since the max. working pressure is 4.3MPa (R22: 3.1MPa), some of the piping and installation and service tools are special.
This air conditioner uses power supply:
Please read these SAFETY PRECAUTIONS carefully to ensure correct installation.
• Be sure to use a dedicated power circuit, and do not put other loads on the power supply.
• Be sure to read these SAFETY PRECAUTIONS carefully before installation.
• Be sure to comply with SAFETY PRECAUTIONS of installation manual, because it contains important safety issues. Definitions
for identifying hazard levels are provided below with their respective safety symbols.
!
WARNING:
Hazards or unsafe practices which COULD result in severe personal injury or death.
!
CAUTION:
Hazards or unsafe practices which COULD result in minor personal injury or product or property damage.
•
Please carefully file indoor and outdoor unit manual away for future reference.
• Installation should be performed by the qualified personnel. Incomplete installation may cause damage by fire, electric shock, drop
or water leakage.
• Perform the installation securely by referring to the installation manual. Incomplete installation could cause a personal injury arising
from fire, electric shock, the unit falling or leakage of water.
• Install the air conditioner on a solid base that can support the unit weight. An inadequate base or incomplete installation may cause
injury due to unit falling off from the base.
• Wiring must be done by a qualified electrician. All the electric works must be performed in accordance with national wiring
regulations and local electrical codes.
• Use the specified type of wire for electrical connections safely. Firmly clamp the interconnecting wires so that their terminals receive
no external stresses.
• For wiring, use a cable long enough to cover the entire distance with no connection, and don't connect multiple devices to the same
AC power supply. Otherwise, it may result in bad contact, poor insulation, unallowable current, and thus result in a fire or electric
shock.
• After all installations are completed, check to make sure that no refrigerant leakage occurs. If the refrigerant gas leakage to the
interior, and the heater, stove flame touching it, will generate harmful substances.
• If the power supply circuit capacity or electrical work is not in place, it may cause a fire or electric shock.
• Attach the electrical cover to the indoor unit and the service panel to the outdoor unit securely.
• If the electrical covers on the indoor unit or the service panel of the outdoor unit are not attached securely, it could result in a fire
or an electric shock due to dust, water, etc.
• Please be sure to cut off the main power supply before the installation of indoor electronic PCB or wiring. Otherwise, it will cause
electric shock.
• Pay attention to protecting the outdoor machine installation location. Avoid people or small animals contact with electrical
components. Please keep the surrounding environment of the outdoor unit clean and tidy.
• When installing or relocating the unit, make sure that no substance other than the specified refrigerant (R32) enters the refrigerant
circuit.
• Any presence of foreign substance such as air can cause abnormal pressure rise or an explosion.
