DANGER
Do not perform installation work, refrigerant piping work, drain pump, drain piping and electrical wiring
connection without referring to our installation manual. If the instructions are not followed, it may result in
a water leakage, electric shock or a fire.
Use the specified non-flamable refrigerant (R410A) to the outdoor unit in the refrigerant cycle.
Do not charge material other than R410A into the unit such as hydrocarbon refrigerants (propane or etc.),
oxygen, flammable gases (acetylene or etc.) or poisonous gases when installing, maintaining and moving
These flammables are extremely dangerous and may cause an explosion, a fire, and injury.
Do not pour water into the indoor or outdoor unit. These products are equipped with electrical parts.
If poured, it will cause a serious electrical shock.
Do not open the service cover or access panel for the indoor or outdoor units without turning OFF the main
power supply.
Do not touch or adjust safety devices inside the indoor unit or outdoor units. If these devices are touched
or readjusted, it may cause a serious accident.
Refrigerant leakage can cause difficulty with breathing due to insufficient air. Turn OFF the main switch,
extinguish any naked flames and contact your service contracto , if refrigerant leakage occurs.
Make sure that the refrigerant leakage test should be performed.
Refrigerant (Fluorocarbon) for this unit is incombustible, non-toxic and odorless.
However if the refrigerant is leaked and is contacted with fire, toxic gas will generate
Also because the fluorocarbon is heavier than air , the floor surface will be filled with it, which could
cause suffocation.
The installer and system specialist shall secure safety against refrigerant leakage according to local
regulations or standards.
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.
Do not install the outdoor unit where there is high level of oil mist, flammable gases, salty air or harmful
gases such as sulfur.
For installation, firmly connect the refrigerant piping befor the compressor starts operating.
For maintenance, relocation and disposal, remove the refrigerant piping after the compressor stops.
Do not perform a short-circuit of the protection device such as a pressure switch when operating.
It may cause a fire and explosion.
