l
Do not perform the 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, an electric shock or a re.
l
Use the specied non-ammable refrigerant (R410A) to the outdoor unit in the refrigerant cycle.
Do not charge the unit with materials other than R410A, such as hydrocarbon refrigerants (propane or
etc.), oxygen, ammable gases (acetylene or etc.) or poisonous gases when installing, maintaining and
moving the unit. These ammables are extremely dangerous and may cause an explosion, a re, and an
injury.
l
Do not pour water into the indoor unit or outdoor unit. These products are equipped with electrical parts.
If water is poured, it will cause a serious electrical shock.
l
Do not open the service cover or access panel for the indoor or outdoor unit without turning OFF the main
power supply.
l
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.
l
Refrigerant leakage may lead to insufcient air and cause difculty with breathing. Turn OFF the main
switch, extinguish all naked ames and contact your service contractor, if refrigerant leakage should occur.
l
Make sure that the refrigerant leakage test has been performed.
Refrigerant (Fluorocarbon) for this unit is non-ammable, non-toxic and odorless.
However if the refrigerant should leak and contact with re, toxic gas will be generated.
Also because the uorocarbon is heavier than air, it settles near the oor, which could cause suffocation.
l
The installer and system specialist shall secure safety against refrigerant leakage according to the local
regulations or standards.
l
Use an ELB (Earth Leakage Breaker).
If it is not used, there is danger of an electric shock or re in the event of a fault.
l
Do not install the outdoor unit where there is high level of oil mist, ammable gases, salty air or harmful
gases such as sulfur.
l
For installation, rmly connect the refrigerant pipe before the compressor starts operating.
For maintenance, relocation and disposal, remove the refrigerant pipe after the compressor stops.
l
Do not perform a short circuit of the protection devices such as the pressure switch during operation.
It may cause a re and an explosion.
l
Do not alter the product and the electrical wiring. It will cause a serious accident.
