• For the refrigerant recovery work (collection of refrigerant from the pipe to the compressor), stop the
compressor before disconnecting the refrigerant pipe.
If the refrigerant pipe is disconnected while the compressor is working with the valve open, the compressor sucks air
and the refrigeration cycle is over pressurized, which may cause a burst or injury.
• Before carrying out the installation, maintenance, repair or removal work, set the circuit breaker to the OFF
position.
Otherwise, electric shocks may result.
• Do not touch the aluminum fin of the unit. You may injure yourself if you do so. If the fin must be touched for
some reason, first put on protective gloves and safety work clothing, and then proceed.
• Install the air conditioner securely in a location where the base can sustain the weight adequately. If the
strength is not enough, the unit may fall down resulting in injury.
• Install a circuit breaker that meets the specifications in the installation manual and the stipulations in the
local regulations and laws.
• Install the circuit breaker where it can be easily accessed by the agent.
• Under no circumstances the power wire must not be extended. Connection trouble in the places where the
wire is extended may give rise to smoking and/or a fire.
• Upon completion of the installation work, tell the user where the circuit breaker is located. If the user does
not know where the circuit breaker is, he or she will not be able to turn it off in the event that trouble has
occurred in the air conditioner.
CAUTION
• This air conditioner adopts the HFC refrigerant (R410A) which does not destroy ozone layer.
• The characteristics of R410A refrigerant are; easy to absorb water, oxidizing membrane or oil, and its pressure is
approx. 1.6 times higher than that of refrigerant R22. Accompanied with the R410A refrigerant, refrigerating oil has
also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating
oil does not enter the refrigerating cycle.
• To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging port of
the main unit and installation tools are changed from those for the conventional refrigerant.
• Exclusive new tools are required for the R410A refrigerant.
• For connecting pipes, use new and clean piping designed for R410A, and make sure that water or dust does not
enter.
• Tighten the flare nut with a torque wrench in the specified manner.
Excessive tightening of the flare nut may cause a crack in the flare nut after a long period, which may result in
refrigerant leakage.
• Wear heavy gloves during the installation work to avoid injury.
