CAUTION

Hold the torque wrench at its grip, keeping it at a right angle with the pipe, in order to 
tighten the 

fl

 are nut correctly.

Tighten the 

fl

 are nuts with a torque wrench using the speci

fi

 ed tightening method. 

Otherwise, the 

fl

 are nuts could break after a prolonged period, causing refrigerant to 

leak and generate hazardous gas if the refrigerant comes into contact with a 

fl

 ame.

When the 

fl

 are nut is tightened properly by your hand, hold the body side coupling with a 

separate spanner, then tighten with a torque wrench.

CAUTION

Be sure to install the pipe against the port on the indoor unit and the outdoor unit 
correctly. If the centering is improper, the 

fl

 are nut cannot tightened smoothly. If the 

fl

 are nut is forced to turn, the threads will be damaged.

Do not remove the flare nut from the indoor unit pipe until immediately before 
connecting the connection pipe.

Do not use mineral oil on 

fl

 ared part. Prevent mineral oil from getting into the system 

as this would reduce the lifetime of the units.

4.4. Installing heat insulation

Install the heat insulation material after performing a refrigerant leak check (see the Instal-
lation Manual for the outdoor unit for details).

COUPLER HEAT INSULATION

•  Insulate by the coupler heat insulation (Accessories) around the gas pipe and liquid 

pipe of indoor side.

•  After installing the coupler heat insulation, wrap both end with vinyl tape so that there is 

no gap.

• After af

fi

 xing the coupler heat insulation, secure it with 2 binders, one on each end of 

the insulation.

•  Make sure that the binders overlap the heat insulation pipe.

And 

fi

 nally 

fi

 x connection pipe (Liquid) to connection pipe (Gas) by rolling vinyl tape over 

coupler heat insulation (Gas) and coupler heat insulation (Liquid).

 

CAUTION

After checking for gas leaks (refer to the Installation Manual of the outdoor unit), 
perform this section.

Install heat insulation around both the large (gas) and small (liquid) pipes. Failure to 
do so may cause water leaks.
