Safety Precautions

 WARNING

• After connecting all wires be sure to shape the cables so that they do not put undue stress on the electrical covers, 

panels or terminals.

Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, fire or equipment damage.

• When installing or relocating the system, be sure to keep the refrigerant circuit free from all substances other than 

the specified refrigerant (R410A), such as air.

(Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise which may result in rupture, resulting 
in injury.)

• During pump-down, stop the compressor before removing the refrigerant piping.

If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed, 
causing abnormally high pressure which could lead to equipment damage or and personal injury.

• During installation, attach the refrigerant piping securely before running the compressor.

If the refrigerant pipes are not attached and the stop valve is open during pump-down, air will be sucked in when the compressor is run, 
causing abnormally high pressure which could lead to equipment damage and personal injury.

• Be sure to install a ground fault circuit interrupter breaker.

Failure to install a ground fault circuit interrupter breaker may result in electrically shocks, or fire personal injury.

 CAUTION

• Do not install the air conditioner where gas leakage would be exposed to open flames.

If the gas leaks and builds up around the unit, it may catch fire.

• Establish drain piping according to the instructions of this manual.

Inadequate piping may cause water damage. 

• Tighten the flare nut according to the specified torque. A torque wrench should be used.

If the flare nut is tightened too much, the flare nut may crack over time and cause refrigerant leakage.

• Do not touch the heat exchanger fins.

Improper handling may result in injury.

• Be very careful about product transportation.

Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dangerous.

• Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shelter by small 

animals.

Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep the area around 
the unit clean.

• The temperature of refrigerant circuit will be high, please keep the inter-unit wire away from copper pipes that are 

not thermally insulated.

• Electrical work must be performed in accordance with the NEC/CEC by authorized personnel only.
