WARNING
Ask a qualifi ed technician to perform the installation.
A faulty installation carried out by the customer himself/herself may cause a water leakage, electric shock or fi re.
Perform the installation properly by following this Installation Manual.
Otherwise, a faulty installation may cause water leakage, electric shock or fi re.
Be sure to always use the parts accessories or the specifi ed parts for installation.
Failure to use the specifi ed parts may cause the equipment to fail, water leakage, electric shock or fi re.
Install the equipment in a location that is out of reach of children.
During installation and relocation of air conditioner, do not allow air or any substances other than the specifi ed refrigerant
(R410A) to enter the refrigerant cycle.
Air or any other substances entered in the refrigerant cycle may cause abnormally high pressure in the refrigerant cycle,
which could result in explosion or personal injury. For additional information, refer to the R410A MSDS.
Ventilate the area if there is a refrigerant leak while performing the installation.
If the refrigerant gas comes into contact with an open fl ame, it can generate toxic fumes.
Be sure to check that there are no refrigerant leaks after installation is completed.
If there is refrigerant gas leak indoors and comes into contact with an open flame from such sources as a fan heater,
Bunsen burner, or stove, it can generate toxic fumes.
When installing this system in high humidity locations, install using Ground fault equipment breakers (often referred to in
other countries as an ELCB earth leakage current breaker) to reduce the risk of leaking current which may result in electric
shock or potential fi re.
CAUTION
Do not install in a location where there is risk of leaking fl ammable gas.
In the event that a gas leak should occur, gas build up around the equipment can cause fi re.
It is not necessary to provide drainage for Branch box.
This equipment is for indoor use only.
Secure the fl are nuts according to the specifi ed method such as using a torque wrench.
Over-tightening the fl are nuts can result in cracking or breaking after a long period of time, and thus cause a refrigerant
leak.
