Safety precautions
SEVERE WARNING SIGNS
Consult qualied installer or dealer for installation.
When installation is done by unqualied person, problems such as water leakage, electric shock or re may occur.
Installation work must be done properly according to this installation manual.
When installation is not done properly, it may cause water leakage, electric shock or re.
When installing the unit in a small room, take measure to keep the refrigerant concentration from exceeding allowable
safety limits in case of refrigerant leakage. Consult the dealer for precautionary measure before the installation.
When refrigerant leaks and exceed dangerous concentration level, it may cause suocation accidents.
If any gas or impurities, except R-410A refrigerant, come into the refrigerant pipe, serious problem may occur and it
may cause injury.
Use the supplied accessories, specied components and tools for the installation.
Do not use the pipe and the installation product used for the R-22 refrigerant.
Failure to use the specied components can cause product fall down, water leakage, electrical shock, and re. (The pipe
and are components used for R-22 refrigerant must not be used)
Install the outdoor unit on a hard and even place that can support its weight.
If the place cannot support its weight, the outdoor unit may fall down and it may cause injury.
Check the following before installation and service work.
Before welding, remove dangerous and inammable things that may cause an explosion and re around the work.
Before welding, remove the refrigerant from inside the pipe or the product.
- If you perform welding while refrigerant is in the pipe, it may increase the pressure of the refrigerant and cause the pipe
to burst. If the pipe bursts or explodes, it may cause severe injury to the installer.
When welding, use the nitrogen gas to eliminate oxidation inside the pipe.
Do not modify the product on your own.
Potential risk of electric shock, re, product failure or injury.
Fix the outdoor unit securely on foundation to resist strong wind or earthquake.
If the outdoor unit is not properly xed, it turns over and accidents may occur.
Electric work must be done by qualied persons, complying the national wiring regulations and installed according to
the instruction stated in the installation manual with leased circuit.
Capacity shortage on the leased circuit and improper installation may cause electric shock or re.
Make sure to perform grounding work.
Do not connect the ground wire to a gas pipe, water pipe, lightning rod or telephone grounding. Improper grounding
could cause electric shock.
