,/h, When you see this symbol on
the unit and in instructions or manuals, be alert to the potential for personal injury. Understand these signal words: DANGER, WARNING, and CAUTION.
These words are used with the safety-alert symbol.
DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies hazards which could result in personal
injury or death. CAUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage. NOTE is used to
highlight suggestions which will result in enhanced installation, reliability, or operation.
• Before installation, please read these precautions for safety carefully.
Be sure to follow the precautions provided here to avoid safety risks. The symbols and their meanings are shown below.

New refrigerant
air conditioner
installation
* THIS AIR CONDITIONER
USES THE HFC REFRIGERANT
(R410A), WHICH DOES NOT DESTROY THE OZONE LAYER.
R410A refrigerant is affected by impurities such as water and oils because the pressure of R410A refrigerant is approx. 1.6 times of refrigerant R22.
ALSO NEW OILS ARE USED WITH R410A, THUS ALWAYS USE NEW REFRIGERANT PIPING AND DO NOT ALLOW MOISTURE OR DUST TO
ENTER THE SYSTEM.
To avoid mixing refrigerant and refrigerant machine oil, the sizes of charging port on the main unit is different than those used on R22 machines and
different tools wilt be required.
* EQUIPMENT
DAMAGE
HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
Do not bury more than 36 in. (914 mm) of refrigerant pipe in the ground. If any section of pipe is buried, there must be a 6 in. (152 mm) vertical rise to
the valve connections on the outdoor units. If more than the recommended length is buried, refrigerant may migrate to the cooler buried section during
extended periods of system shutdown. This causes refrigerant slugging and could possibly damage the compressor at start-up.
....
FOR USE BY QUALIFIED PERSONS ONLY.
TURN OFF MAIN POWER SUPPLY BEFORE ATTEMPTING ANY ELECTRICAL WORK. MAKE SURE ALL POWER SWITCHES ARE OFF.
FAILURE TO DO SO MAY CAUSE ELECTRIC SHOCK.
CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING CABLE IS CONNECTED WRONGLY, ELECTRIC PARTS MAY BE
DAMAGED.
CHECK THAT THE EARTH GROUND WIRE IS NOT BROKEN OR DISCONNECTED BEFORE INSTALLATION.
....
DO NOT INSTALL THE UNIT NEAR CONCENTRATIONS
OF COMBUSTIBLE GAS OR GAS VAPORS.
FAILURE TO FOLLOW THIS INSTRUCTION CAN RESULT tN FIRE OR EXPLOSION.
TO PREVENT OVERHEATING THE INDOOR UNIT AND CAUSING A FIRE HAZARD, PLACE THE UNiT WELL AWAY (MORE THAN 2 M) FROM
HEAT SOURCES SUCH AS RADIATORS, HEATERS, FURNACE, STOVES, ETC.
WHEN RELOCATING THE AIR CONDITIONER, BE VERY CAREFUL NOT TO MIX THE SPECIFIED REFRIGERANT (R410A) WITH ANY OTHER
GASEOUS BODY INTO THE REFRIGERATION CYCLE. IF AIR OR ANY OTHER GAS IS MIXED WITH THE REFRIGERANT, THE GAS PRESSURE
IN THE REFRIGERATION CYCLE BECOMES ABNORMALLY HIGH AND IT RESULTINGLY CAUSES BURST OF THE PiPE AND INJURIES ON
PERSONS.
....
IN THE EVENT OF REFRIGERANT LEAKAGE DURING INSTALLATION, ALLOW FRESH AIR INTO THE ROOM IMMEDIATELY. IF THE
REFRIGERANT GAS IS HEATED BY FIRE OR OTHER MEAN, IT GENERATES POISONOUS GAS.
