However, for existing ceilings, install fresh air inlet component kit and branch duct before installing the unit. As for the parts to be used for installation work, be sure to use the provided accessories and specified parts designated by our company.
Page 123 Installation of indoor unit EDUS281120_a <Ceiling work> (1-3)Adjust the unit to the right position for installation. (Refer to “4. PREPARATIONS BEFORE INSTALLATION-(1)”.) • Using the Installation guide (15) allows you to check the positions from the underside of the unit to the lower ceiling surface.
Page 124 EDUS281120_a Installation of indoor unit CAUTION • Use a pipe cutter and flare suitable for the type of refrigerant. • Apply ester oil or ether oil around the flare section before connecting. • To prevent dust, moisture or other foreign matter from infiltrating the tube, either pinch the end or cover it with tape.
Page 125 Installation of indoor unit EDUS281120_a Not recommendable but in case of emergency You must use a torque wrench but if you are obliged to install the unit without a torque wrench, you may follow the installation method mentioned below.

Page 126 EDUS281120_a Installation of indoor unit CAUTION CAUTION TO BE TAKEN WHEN BRAZING REFRIGERANT PIPING “Do not use flux when brazing refrigerant piping. Therefore, use the phosphor copper brazing filler metal (BCuP-2/B-Cu93P-710/795) which does not require flux.” (Flux has extremely harmful influence on refrigerant piping systems. For instance, if the chlorine based flux is used, it will cause pipe corrosion or, in particular, if the flux contains fluorine, it will damage the refrigerant oil.) •...
